This Satechi 72W USB-C car charger is one of these devices

Previously, I had covered the use of high-capacity USB-C Power-Delivery-compliant powerbanks that serve as an external battery pack for your laptop or tablet. Now I am looking at the idea of USB-C Power-Delivery-compliant car chargers that do the same thing but work from your vehicle’s or boat’s DC power infrastructure.

You may think about using the computer’s AC-based charger along with an inverter but this can be too cumbersome to deal with. As well, there are inefficiencies that this approach comes with due to converting the electric current twice – from 12-24 volts DC to 110-250 volts AC in the inverter then down to 5-12 volts DC in the AC-powered charger for your laptop to use.

But there are a few car chargers compliant to the USB-C Power Delivery standard that put up at least 45 watts. There are even some that can put up at least 60 or 65 watts, if not 90 watts in order to cater towards the more powerful computers that are appearing.

Even something like this Dell XPS 13 can be used in the car from the vehicle’s power supply without the need for an inverter if you are using a USB-C PD car charge with at least 45W

All of these plug in to a vehicle’s or boat’s DC accessory power outlet, commonly known as a “cigar-lighter” socket due to the use of these sockets for a “push-in” thermal cigar lighter. But most of these will work between 12 volts to 24 volts DC, allowing for use in large trucks, buses, large boats and the like that work on 24V. The vehicle will have to be wired for negative earthing which has been the accepted standard for vehicle wiring since the late 1960s.

You may also find that some portable solar-power setups pitched at campers will offer 12-volt DC power through the “cigar-lighter” accessory socket, so you could run your equipment from solar power while in the bush.

Some of these chargers have a standard USB Type-A socket to supply power for charging smartphones, mobile-platform tablets or accessories using the traditional USB charging cable. It is of importance if you are using something like a Mi-Fi router or a mobile printer or scanner.

What can you do with these chargers? You can top up a laptop’s battery while you are driving so as to have more power on hand when you are at your destination. This will please field workers who are more likely to work in rural or remote settings where there isn’t the likelihood to have AC power readily available.

If you are a passenger and you use your laptop or tablet while travelling in a vehicle or boat, these adaptors ae still relevant as a way to save battery runtime. For example, you may be catching up with some work while you are being driven to an appointment or a kid may want to play a game or watch a video to while away that long car trip.

Even at your destination, you may find that you want to “spin out” your laptop’s or tablet’s battery runtime by running it from your vehicle’s or boat’s DC power using one of these adaptors.

For mobile workers whose vehicle is their office, it may be about doing some of the site-based “homework” on a laptop or tablet. But you don’t want to run the computer’s battery down deeply during, say, sending off some email or editing pictures.

This may also appeal to motorhome or boat users whose vehicle’s or craft’s main supply of auxiliary power is the 12-volt or 24-volt DC power available from an accessory power socket. Here, a lot of these users would be relying on a laptop or tablet for communications or entertainment while they are travelling.

What I also see of this is newer compact yet powerful power-supply designs also affecting this class of power supply. This is with more of these car chargers providing USB-PD-compliant power of at least 90 watts from 12-24 volts DC power sources including some that provide two or more “rails” of USB-C PD-compliant power from the same power input.

So at least keep an eye out for USB-C PD-compliant car chargers that put up at least 45W, if not 65W, of power and consider them as a viable laptop accessory if you think of your ultraportable laptop being used on the road.

My Comments

Recently  Dell has released the XPS 17 laptop which is capitalising on what their XPS range of laptops is all about – a premium-positioned value-for-money range of ultraportable or “thin-and-light” laptop computers.

Here, the Dell XPS 17 is a 17” slimline desktop-replacement laptop that appeals to those of us who value the larger screen size for content creation. A review published by the Australian described it as being fit for use at work or home or in a hotel room rather than being always taken around a conference or university campus. I would sum this up as simply where you don’t expect to carry it around many times in a day.

The baseline variant which has an Intel Core i5 CPU, 8Gb RAM, 512Gb solid-state storage and Full HD non-touch display also uses Intel UHD integrated graphics as its graphics infrastructure. This is while the other configurations use NVIDIA Geforce GTX 1650 Ti graphics infrastructure with 4Gb display memory along with the Intel Core i7 CPUs.

But, like the rest of the lineup, it has four Thunderbolt 3 over USB-C sockets which allows it to be used with an external graphics module. This is something I appreciate for those of us who may want to save money in the initial purchase of one of these machines but can look towards saving towards purchasing an external graphics module that has the graphics power that suits our needs at a later time.

Two of the higher-end variants have a 4K UHD touch display which would have appeal towards content creation and make best use of the screen size. The only limitation about this would be that the laptop will be more thirsty when it comes to battery runtime. For some people especially content creators, this may be a non-issue if the Dell XPS 17 is expected to be used primarily on external power.

What is happening with Dell and their XPS laptop product lineup is that they are creating Windows-based computers that answer what most of us are after while delivering a very well-built product. They are even getting to a point where they can provide a viable Windows answer to the Apple MacBook lineup.

Qualcomm Announces First 5G Snapdragon 6-Series Mobile Platform (Press Release)

My Comments

5G mobile broadband technology will be coming to an affordable smartphone near you thanks to a new chipset that Qualcomm has now launched.

This chipset, known as the Qualcomm Snapdragon 690 chipset doesn’t just have a 5G modem for this class of product but also has processing power to handle some high-end tasks like 192 megapixel high-resolution photography or 4G HDR videography. There will also be support for Wi-Fi 6 (802.11ax) and Bluetooth 5.1 technology along with support for improved artificial-intelligence / machine-learning. It is although Qualcomm haven’t built mmWave support in to the 5G mobile broadband modem.

The silicon is being rolled out at the moment and will have a low bill-of-materials price compared to premium or midrange chipsets that Qualcomm offers. This will mean that a finished Android smartphone product would be expected to retail between USD$300-USD$500 before any telco subsidies. This is compared to the Apple iPhone SE which is a4G only product going for USD$400.

Phones based on this chipset will typically be manufactured by the likes of LG, Motorola, HMD Global (Nokia), Sharp, TCL (Alcatel) and the like. This will include various original-equipment-manufacturers who specialise in selling products under a private-label agreement with the distributor, retailer or telco.

The coronavirus plague, with the various event and business shutdowns associated with it, has  thrown a spanner in the works regarding bringing 5G mobile broadband in to the mainstream. As well there hasn’t been much market interest in newer smartphone technology and there would be a strong market for affordable smartphones thanks to people concerned about how much they spend, forced by the COVID-19-driven financial downturn.

But this chipset may also be about allowing manufacturers to take less of a gamble when it comes to creating a smartphone or tablet product that embodies a unique form of innovation or answers a particular market’s needs. An example that could come to mind would be a smartphone that has its radio circuitry optimised for long-range reception and pitched for rural and remote areas. Similarly, LG could pull it off again with a smartphone that has a DAB+ digital-radio tuner that would have a greater zone of relevance thanks to more European countries running DAB+ digital radio full time.

What is being highlighted here is that Qualcomm is making it feasible to provide 5G mobile broadband technology at a price affordable for the masses.

My Comments

The 5G mobile broadband specification is surfacing this week in an “Always Connected PC” form factor with integrated mobile broadband thanks to Lenovo.

The computer will be the Lenovo Flex 5G also known as the Yoga 5G in some markets and is a 14” 2-in-1 convertible laptop. This uses ARM RISC silicon in the form of a Qualcomm Snapdragon 8cx CPU and Qualcomm Adreno 680 graphics infrastructure. It will be delivered with the ARM-compiled build of Windows 10 Pro. Its display is a 14” Full HD LED LCD and will come with 8Gb RAM and 256Gb SSD storage.

Lenovo Yoga 5G convertible notebook press image courtesy of LenovoThe use of a Qualcomm Snapdragon 8cx as the Lenovo Flex 5G’s CPU is primarily about implementing CPU technology that has higher performance compared to what is offered in a smartphone or mobile-platform tablet. This is due to the computer being in a larger chassis and not having the thermal constraints associated with the kind of housing a smartphone would have.

For connectivity, the 5G mobile broadband modem supports mmWave and sub 6GHz bands, similar to what is expected in the latest high-end smartphones. As well, it can connect to Wi-Fi 5 (802.11ac) networks and Bluetooth peripherals up to the Bluetooth 5.0 specification. Lenovo expects the Flex 5G to run on its own battery for 24 hours before needing to be charged.

Of course, due to the use of ARM RISC silicon, the Windows ARM build will be running Windows software that isn’t compiled for ARM RISC microarchitecture in an emulation form. This may be seen to yield compatibility issues for some software like games or device drivers.

Initially it will be offered in the USA through Verizon for USD$1400 or USD$58.33 per month as part of a contract. But Lenovo is forging partnerships with other telcos in other markets like EE (UK), Sunrise (Switzerland) or CMCC (China) as well as offering it direct through its Website later this year.

What I see of this is that Lenovo being the first to offer 5G mobile-broadband integration in a regular computer. There will be issues with having to support certain markets’ and telcos’ mobile-broadband needs such as Telstra’s wish to support proper performance in regional, rural and remote areas of Australia when they sell any mobile-broadband device. This will mean having to vary the device to suit these requirements.

At the moment, I see this class of computer appealing towards mobile professionals and nomadic users who prefer to use mobile broadband as the preferred Internet connection away from the office.

White Paper

My Comments

Telstra has fronted up with their latest premium portable mobile broadband router for the 5G mobile-broadband infrastructure. But this “Mi-Fi” known as the Telstra 5G Wi-Fi Pro ticks all the boxes as far as being future-proof is concerned.

Here, on the WAN (Internet) side, this device supports 5G with mmWave technology while on the LAN (local network) side, it works on the latest Wi-Fi 6 standard for 2.4GHz and 5GHz bands thus bringing your mobile network up to date with the latest standards.Of course it can work with existing 4G LTE networks and exploits what Telstra has to offer in this context.  This has a 4500mAh battery that can be removed and can run for nine hours providing full data transfer. It can be charged via a USB-C connection according to the QC 3.0 protocol and the open-frame Power Delivery 2.0 protocol, meaning you can charge it with your brand-new Ultrabook’s charger or run it for a long time using a USB-C PD powerbank.

The Telstra 5G Wi-Fi Pro costs AUD$599 straight up. Or you could buy this device on a post-paid Telstra service plan for AUD$24.95 / month on 24-month plan plus mobile data plan the cost of the mobile-broadband data service.

What is this mmWave 5G mobile broadband all about?

The mmWave 5G mobile broadband technology is an extremely-high-frequency variant of 5G mobile broadband technology which works between 24GHz to 100GHz. Telstra’s initial trial run of this technology at Gold Coast worked on 26GHz. The same technology has been sued with various fixed point-to-point wireless links and satellite-Internet services but is use as a mobile broadband technology is what is being identified here.

Due to the very short wavelength, mmWave 5G technology will have a short operating range of a few hundred metres from the base station. This means that to cover a significant area, the service provider will need to install many “femtocell” base stations across the area and they will typically operate at a signal strength similar to a Wi-Fi access point or router. It means that the electromagnetic energy levels are 1000 times below the maximum energy level expected for safe operation.

Therefore mmWave 5G technology is pitched for operating environments where there is a high concentration of users so as to avoid “loading” very few base stations with many users, thus denying the users adequate bandwidth. This is a situation most of us will have experienced when attempting to benefit from an Internet resource on our mobile devices while on a packed commuter train.

Here, you will see this technology be used at busy public-transport interchanges including airports; event venues like convention centres or sports stadiums; or shopping centres. You may even find it being used in high-rise residential, commercial and hotel developments where there is expected to be many people within the development.

At the moment, Telstra has to license the necessary spectrum in order to set up a mmWave 5G service and will need to see other devices come on board prepared for this technology.

mmWave 5G mobile broadband will simply be pressed in to service as a complementary technology to the existing 5G mobile broadband technologies. In this case it is about highly-concentrated operating environments with many devices.

The two-box voice-driven home assistant setup is being made real with Bluetooth

Bang & Olufsen Beosound A1 2nd Generation Bluetooth smart speaker that works with a smartphone or similar devicce to benefit from Amazon Alexa

B&O Beosound A1 (2nd Gen) Announced With Alexa Integration | Ubergizmo

My Comments

At the moment, there is the latest generation of the Bose QuietComfort 35 noise-cancelling Bluetooth headset that implements a software link with the Google Assistant voice driven personal assistants through its own app. Now Bang & Olufsen have come up with the Beosound A1 Second Generation battery-operated Bluetooth speaker that has integration with the Amazon Alexa voice-driven home assistant platform.

But what are these about?

Bluetooth smart speaker diagram

How the likes of the B&O Beosound A1 work with your smartphone, tablet or computer to be a smart speaker

These are purely Bluetooth audio peripherals that connect to your smartphone which links with the Internet via Wi-Fi or mobile broadband. This is usually facilitated with a manufacturer-supplied app for that device that you install on your smartphone or tablet. You will also have to install the client software for the voice-driven assistant platform if your smartphone or tablet doesn’t have inherent support for that platform.

The Bose solution primarily used their app to “map” a secondary function button on the headset to activate Google Assistant. Then the B&O approach had the Beosound A1 and your smartphone or similar mobile-platform device work together as if it is an Amazon Echo.

Why do I see this as a significant trend for “smart-speaker” and allied device use cases, especially as Google, Amazon and the Voice Interoperability Initiative want to extend their voice-driven assistant platforms to setups based around Bluetooth audio peripherals. Here it underscores the reality that the highly-capable host devices will have Internet connectivity via a mobile-broadband connection or a local-area network.

One is to allow manufacturers to provide a highly-portable approach towards using Alexa or Google Assistant while on the move. Similarly, this approach will appeal to those in the automotive and marine infotainment sector with the idea of end-users bringing their own Internet connection with them while in their car or boat but wanting to use their preferred voice-driven assistant platform there.

Some technology manufacturers may look at the idea of a two-piece setup with a specially-designed Bluetooth speaker that links with a device that is normally connected to the Internet like a set-top box or router and both devices working in a smart-speaker capacity. Here, it can be about a cost-effective smart-speaker platform or to enable the use of battery-operated devices that use battery-efficient technologies.

After what Bose and B&O are doing, it could be about bringing the idea of a two-box smart-speaker setup for voice-driven assistant platforms opening up some interesting pathways.

My Comments

Of late, the personal-IT press have identified a 13” ultraportable laptop computer that has set a benchmark when it comes to consumer-focused computers of that class. This computer is the Dell XPS 13 family of Ultrabooks which are a regular laptop computer family that runs Windows and is designed for portability.

What makes these computers special?

A key factor about the way Dell had worked on the XPS 13 family of Ultrabooks was to make sure the ultraportable laptops had the important functions necessary for this class of computer. They also factored in the durability aspect because if you are paying a pretty penny for a computer, you want to be sure it lasts.

As well, it was all part of assuring that the end-user got value for money when it came to purchasing an ultraportable laptop computer.

In a previous article that I wrote about the Dell XPS 13, I compared it to the National Panasonic mid-market VHS videocassette recorders offered since the mid 1980s to the PAL/SECAM (Europe, Australasia, Asia) market; and the Sony mid-market MiniDisc decks offered through the mid-late 1990s. Both these product ranges were worked with the focus on offering the features and performance that count for most users at a price that offers value for money and is “easy to stomach”.

Through the generations, Dell introduced the very narrow bezel for the screen but this required the typical camera module to be mounted under the screen. That earnt some criticism in the computing press due to it “looking up at the user’s nose”. For the latest generation, Dell developed a very small camera module that can exist at the top of the screen but maintain the XPS 13’s very narrow bezel.

The Dell XPS 13 Kaby Lake 2-in-1 convertible Ultrabook variant

The Dell XPS 13 is able to be specified with the three different Intel Core CPU grades (i3, i5 and i7) and users could specify it to be equipped with a 4K UHD display option. The ultraportable laptop will have Intel integrated graphics infrastructure but the past two generations of the Dell XPS 13 are equipped with two Thunderbolt 3 ports so you can use it with an external graphics module if you want improved graphics performance.

There was some doubt about Dell introducing a 2-in-1 convertible variant of the XPS 13 due to it being perceived as a gimmick rather than something that is of utility. But they introduced the convertible variant of this Ultrabook as part of the 2017 Kaby Lake generation. It placed Dell in a highly-competitive field of ultraportable convertible computers and could easily place a focus towards “value-focused” 2-in-1 ultraportables.

What will this mean for Dell and the personal computer industry?

The question that will come about is how far can Dell go towards improving this computer. At the moment, it could be about keeping each generation of the XPS 13 Ultrabook in step with the latest mobile-focused silicon and mobile-computing technologies. They could also be ending up with a 14” clamshell variant of this computer for those of us wanting a larger screen size for something that comfortably fits on the economy-class airline tray table.

For the 2-in-1 variant, Dell could even bring the XPS 13 to a point where it is simply about value for money compared to other 13” travel-friendly convertible ultraportables. Here, they would underscore the features that every user of that class of computer needs, especially when it comes to “on-the-road” use, along with preserving a durable design.

Other computer manufacturers will also be looking at the Dell XPS 13 as the computer to match, if not beat, when it comes to offering value for money in their 13” travel-friendly clamshell ultraportable range. This can include companies heavily present in particular market niches like enterprise computing who will use what Dell is offering and shoehorn it to their particular niche.

Best value configuration suggestions

Most users could get by with a Dell XPS 13 that uses an Intel Core i5 CPU, 8Gb RAM and at least 256Gb solid-state storage. You may want to pay more for an i7 CPU and/or 16Gb RAM if you are chasing more performance or to spend more on a higher storage capacity if you are storing more data while away.

If there is an expectation to use your XPS 13 on the road, it would be wise to avoid the 4K UHD screen option due to the fact that this resolution could make your Ultrabook more thirstier to run on its own battery.

The 2-in-1 convertible variant is worth considering if you are after this value-priced ultraportable in a “Yoga-style” convertible form.

Conclusion

What I have found through my experience with the Dell XPS 13 computers along with the computer-press write-ups about them is that Dell has effectively defined a benchmark when it comes to an Intel-powered travel-friendly ultraportable laptop computer.

Product Review–Brother DSMobile DS-940DW mobile scanner

Introduction

I am reviewing the Brother DSMobile DS-940DW Wi-Fi mobile scanner which is a highly-portable pure-play document scanner pitched towards the mobile office.

This battery-powered mobile scanner can scan to a regular computer via a USB connection or via a Wi-Fi link , whether you are using the one it creates or an existing small or home Wi-Fi network. As well, you can use it to scan documents to your iOS or Android mobile device using a Wi-Fi link, either one it creates or an extant small network.

As well, you can use it offline to scan documents to a removable microSD card so you can then download them as files to your computer at a later stage. In this case, you can remove the card and install it in your computer’s SD card reader to get at your documents or while you have the scanner connected to your regular computer you see that SD card as a removable storage device with all your scanned documents.

The clamshell design makes it easy to remove jammed paper.

The Brother DSMobile DS-940DW Wi-Fi mobile scanner is powered from an internal rechargeable battery or an external USB-based power supply which you have to provide. That could be through your computer, a USB charger or a USB powerbank. But the same USB power supply also charges the battery whether you are running the scanner or not.

Connectivity and Setup

The Brother DS-940DW mobile scanner has an easy-to-find slider switch on the right-hand side that selects between SD card operation, direct USB connection and Wi-Fi network connection. This makes it easier for the user to switch between the mode appropriate to their scanning needs, be it to scan to their laptop via USB or to their mobile device via Wi-Fi or simply to scan to the installed SD card.

Direct connection

You connect the scanner to the host computer or a power supply using a USB 3.0 or USB-C cable with a USB 3.0 microB plug on it

If you intend to use the Brother DS-940DW scanner with your regular computer via USB, you connect it to the host computer using a USB 3.0 cable supplied with the scanner.

But if your computer is equipped only with USB-C connectors like some new Ultrabooks or you use a USB-C charger to power your scanner, you would need to purchase a USB Type-C to  USB 3.0 microB cable (OfficeWorks Australia, Office Depot USA, B&H Photo Video USA,Walmart, Amazon) rather than use the supplied USB Type-A cable.

In this case, if you did use the scanner offline and scanned documents to an SD card installed within the machine, the SD card will be presented to your computer’s operating system as another logical storage volume. This is similar to what happens when you are using a USB memory stick or an SD card reader.

Wi-Fi network connection

It is easy to change between WI-Fi, dirrect or offline scanning at the flick of a switch

The scanner can be connected to the computer via a USB cable or via a Wi-Fi network, whether one that it creates or an existing small network. But setting it up to work with an existing Wi-Fi network requires you to work it as its own Wi-Fi access point then log in to a specified Web page which has a “Wireless Setup Wizard” to associate it with the existing network. You can use WPS-based push-button or PIN setup if your access point or router supports these methods. For this function, there is a hardware button located on the side of the scanner near the operation mode switch.

I am identifying the issue of having this mobile scanner on an existing small Wi-Fi network due to the idea of setting up these mobile devices as part of a mobile network where there are more than two devices to be on that network. It is in addition to having this same device work as part of your home or small-business network.

When the Brother DSMobile DS-940DW mobile scanner is connected to the host computer via USB, it exposes a Mass Storage device class for the internal microSD card reader. This is in conjunction to vendor-specific devices that depend on the host computer running a Brother-supplied driver and scan-monitor software.

There is a default arrangement that if you enable Wi-Fi mode on the scanner, it will check for previously-configured networks before it goes to own-access-point mode which is indicated by a steady Wi-Fi light. Successful connection to a previously-configured network is simply identified by a steady Wi-Fi light after a bit of flashing.

Software installation

If you are setting the Brother DS-940DW mobile scanner to work with your regular computer, you would need to install the drivers from the Brother support Website for this machine to work. You will also be supplied with the Brother iPront&Scan software which can do most of the essential scanning tasks.

Brother throws in complementary software like a business-card scanning app so you can scan your pile of customers’ or business partners’ business cards in to a contact-management database. This is software you can install when you download the driver and software package or install at a later date.

Mobile users will need to install the Brother iPrint&Scan app from their mobile platform’s app store. Here, they will need to use this simple software to scan the documents in to their device and “take them further” as they see fit.

Document Handling

Scanning a standard A4 or letter document page

The Brother DSMobile DS-940DW can only handle one page at at time but can scan both sides of that page at once. The double-sided scanning approach is similar to some of Brother’s multifunction printers that use single-pass duplex scanning.

When you scan a document, you need to make sure that the black paper guide is lined up against the original document’s edge before you start the scanning process. Here, you are making sure that the document isn’t skewing or likely to jam.

To deal with paper jams, you press the front of the scanner above the document-feed slot in order to expose the scanning heads to remove the misfed original. Here, the “clamshell approach” makes it easier to rectify any paper jams.

Ready to scan an ID card of standard “credit-card” thickness and with embossing – it can.

The Brother DS-940DW was able to scan ID cards, even those with embossed characters properly. I would see this as being important where users have to scan them to prove a customer’s identity during an “on-the-road” transaction.

Walk-up functions

The Brother DS-940DW has a built-in SDHC-compliant microSD card drive so you can scan documents offline to a microSD card. This is presented to the host computer as a standard USB Mass Storage Device and you use your operating system’s file manager to get at your scanned files which exist on that SD card.

I wouldn’t really expect this to work properly with the idea of showing your scanned photos through a smart TV or similar device that has its own USB port. It is because most of these dedicated-purpose devices don’t do a good job at handling multiple-function devices connected to their USB ports thanks to their firmware not supporting USB hubs as a device class.

Computer functions

I have used the scanner with the Brother iPrint&Scan software and found that it is competent as a basic scanning package whether to store the scan to your computer’s file system or to an online storage service.

At the moment, the Brother iPrint&Scan desktop scanning software works on a “pull-scan” approach where you have to start the scanning job from the software rather than a “push-scan” approach pressing the machine’s START/STOP button to initiate the scan job. This is due to the scan monitor software associated with the machine and providing this functionality not installing properly. I have addressed this issue previously on this site due to various scan-monitor programs taking time to respond properly when you start a scan job on the printer or scanner, with the idea of operating systems undertaking this role.

The Brother DSMobile DS-940DW network mobile scanner works with the Brother iPrint&Scan mobile app available on both the Apple and Google app stores. Here, it worked properly where you can simply save the scan to your mobile device or share it with other apps that handle the supported file types using the “share to” shortcut that iOS and Android provide.

Scan speed and quality

The machine can scan the pages you feed through it quickly and yields a high-quality reproduction of these pages. I had tried it with an ordinary A4 document, a snapshot photo, two till receipts and two ID cards and this was proven for each of them. With the photo, there wasn’t any difference with the colour saturation that was yielded.

If you are scanning till receipts with the scanner, it is a good idea to set the machine or your scanning software to scan the receipt single-sided. This will avoid problems with reverse-side text that may “come through” during the scan which may be a problem with receipts coming from devices that are loaded with “branded” paper that has advertising material printed on the back.

Limitations And Points Of Improvement

A key issue that I found with the Brother DS-940DW mobile scanner was a poor user experience when I enrolled it with an existing Wi-Fi home network from my smartphone. This could be improved upon through having a native mobile platform app for configuring this scanner’s network connectivity. It can include the ability to transfer a network’s connection details that are stored in your mobile device to the scanner as part of configuring that device.

For those of us who use a regular computer and the scanner’s Web user experience for configuring it to work with an existing Wi-Fi network, that user experience could be improved with an indicator that highlights successful connection to that network. As well, a hardware switch could be used to toggle between the scanner’s own network and an existing network, which may come in handy for troubleshooting or if you don’t want to use an existing network that you set up the scanner for.

It could also benefit from the full set of USB 3.1 specifications including the Type-C connection and USB Power Delivery for quick charging. Most likely I would see Brother offer this connection in a newer portable printing devices as the USB Type-C connection becomes the norm for portable computer equipment.

I also see the Brother DSMobile DS-940DW network mobile scanner being an ideal device to implement Mopria Scan driver-free scanning technology (Mopria Alliance press release PDF) which is currently implemented as an app for Android devices.

As well, it could support a transparency-scanning mode that capitalises on the single-pass auto-duplex scan method. Here, one of the scanning heads could simply be a white backlight while the other simply reads the image on the film. This would come in to its own with a wide range of applications like photographers with their negatives and slides, the medical profession with their film-based X-rays or businesses who have archived documents using microfilm and similar technologies.

Conclusion and Placement Notes

I do see the Brother DSMobile DS-940DW network mobile scanner as an agile highly portable pure-play document scanner that can answer many different needs. Here, it works well with anyone whose office is the driver’s seat of a car or the back of a van and can even answer the requirements to use mobile-platform devices as one’s primary workplace technology.

It is easy to consider a mobile scanner, especially a network-capable machine, to be a toy but I do see the Brother DSMobile DS-940DW mobile scanner as a tool. This is more so for mobile workers who need to scan receipts for work transactions incurred while travelling or to scan documents such as work authorisations and customer ID at the customer’s premises.

The fact that you can switch between scanning to an SD card, a USB-connected host or a Wi-Fi-connected host using a hardware switch makes the job of selecting the right mode for the job easier. For example, a mobile professional could switch the scanner over to “scan-to-card” mode and scan the fuel receipt to an SD card installed in the unit and serving as a “digital receipt shoebox”. Then they scan that work authorisation that their customer had signed when they visited and use the Wi-Fi link with their iPad running an email app to send the signed authorisation to their office.

Reverse image searching–a very useful tool for verifying the authenticity of content

Tineye reverse image search

Tineye – one of the most popular and useful reverse image search tools

Article

How To Do A Reverse Image Search From Your Phone | PCMag

My Comments and further information

Increasingly, most of us who regularly interact with the Internet will be encouraged to perform reverse-image searches.

This is where you use an image you supply or reference as a search term for the same or similar images on other Internet resources. It can also be about identifying a person or other object that is in the image.

Increasingly this is being used by people who engage in online dating to verify the authenticity of the person whom they “hit” on in an online-dating or social-media platform. It is due to romance scams where “catfishing” (pretending to be someone else in order to attract people of a particular kind) is part of the game. Here, part of the modus operandi is for the perpetrator to steal pictures of other people that match a particular look from photo-sharing or social-media sites and use these images in their profile.

It also is being used as a way to verify the authenticity of a product being offered for sale through an online second-hand-goods marketplace like eBay, Craigslist or Gumtree. It also extends to short-term house rentals including AirBnB where the potential tenant wants to verify the authenticity of the premises that is available to let.

As well, reverse image searching is being considered more relevant when it comes to checking the veracity of a news item that is posted online. This is very important in the era of fake news and disinformation where online images including doctored images are being used to corroborate questionable news articles.

How do you do a reverse image search?

At the moment, there are a few reverse-image-search engines that are available to use by the ordinary computer user. These include Tineye, Google Image Search, Bing Visual Search, Yandex’s image search function and Social Catfish’s reverse-image-search function.

Dell Inspiron 14 5000 2-in-1 at Rydges Melbourne (Locanda)

A regular computer like this Dell Inspiron 14 5000 2-in-1 makes it easier to do a reverse image search thanks to established operating system and browser code and its user interface.

The process of using these services involves you uploading the image to the service including using “copy-and-paste” techniques or passing the image’s URL to an address box in the search engine’s user interface. The latter method implies a “search-by-reference” method with the reverse-image-search site loading the image associated with that link into itself as its search term.

Using a regular desktop or laptop computer that runs the common desktop operating systems makes this job easier. This is because the browsers offered on these platforms implement tabs or allow multiple sessions so you can run the site in question in one tab or window and one or two reverse-image-search engines in other tabs or windows.

These operating systems also maintain well-developed file systems and copy-paste transfer algorithms that facilitate the transfer of URLs or image data to these reverse-image-search engines. That will also apply if you are dealing with a native app for that online service such as the client app offered by Facebook or LinkedIn for Windows. As well, Chrome and Firefox provide drag-and-drop support so you can drag the image from that Tinder or Facebook profile in one browser session to Tineye running in the other browser session.

But mobile users may find this process very daunting. Typically it requires the site to be opened and logged in to in Chrome or Safari then opened as a desktop version which is the equivalent of viewing it on a regular computer. For Chrome, you have to tap on the three-dot menu and select “Request Desktop Site”. For Safari, you have to tap the upward-facing arrow to show the “desktop view” option and select that option.

Then you open the image in a new tab and copy the image’s URL from the address bar. That is before you visit Google Image Search or Tineye to paste the URL in that app’s interface.

Google has built in to recent mobile versions of Chrome a shortcut to their reverse-image-search function. Here, you “dwell” on the image with your finger to expose a pop-up menu which has the “Search Google For This Image” option. The Bing app has the ability for you to upload images or screenshots for searching.

Share option in Google Chrome on Android

If you use an app like the Facebook, Instagram or Tinder mobile clients, you may have to take a screenshot of the image you want to search on. Recent iOS and Android versions also provide the ability to edit a screenshot before you save it thus cutting out the unnecessary user-interface stuff from what you want to submit. Then you open up Tineye or Google Image Search in your browser and upload the image to the reverse-image-search engine.

How can reverse image searching on the mobile platforms be improved

What can be done to facilitate reverse image searching on the mobile platforms is for reverse-image-search engines to create lightweight apps for each mobile platform. This app would make use of the mobile platform’s “Share” function for you to upload the image or its URL to the reverse-image-search engine as a search term. Then the app would show you the results of your search through a native interface or a view of the appropriate Web interface.

Share dialog on Android

A reverse-image-search tool like Tineye could be a share-to destination for mobile platforms like iOS or Android

Why have this app work as a “share to” destination? This is because most mobile-platform apps and Web browsers make use of the “share to” function as a way to take a local or online resource further. It doesn’t matter whether it is to send to someone else via a messaging platform including email; obtain a printout or, in some cases, stream it on the big screen via AirPlay or Chromecast.

The lightweight mobile app that works with a reverse-image-search engine answers the reality that most of us use smartphones or mobile-platform tablets for personal online activity. This is more so with social media, online dating and online news sources, thanks to the “personal” size of these devices.

Conclusion

What is becoming real is reverse image searching, whether of particular images or Webpages, is being seen as important for our security and privacy and for our society’s stability.

It is worth enquiring about the kind of Wi-Fi Internet service at your hotel or holiday rental you intend to stay at

Article

Harbourside Apartments - one of those serviced-apartment blocks that could benefit from DLNA

If you do value online connectivity, it is worth asking your hotel, motel, holiday rental or similar accommodation about that Wi-Fi Internet service they offer

Ask About A Hotel Or Airbnb’s WiFi Before You Book | Lifehacker

My Comments

When you book that hotel, motel or holiday-rental house like an AirBnB, it may be worth inquiring about the kind of Wi-Fi service the venue has. This is more so where they advertise the availability of Wi-Fi as a headline feature.

In some of these venues, you may come across situations that may impact your online life during your stay.

For example, you may come across a short-term holiday rental that is set up with an el-cheapo Internet-service plan where there isn’t much in the way of included data allowance and the use of multimedia content like Netflix, Internet radio or YouTube; or IP-based voice and video telephony by guests may chew through this allowance. Similarly, the facility may only be provided with a connection that doesn’t have much in the way of bandwidth, a reality with properties located out of major towns.

Hotels and similar locations can have their fair share of Wi-Fi Internet limitations. For example, they could include baseline Wi-Fi Internet for one device as part of the accommodation deal but charge extra for higher bandwidth or concurrent use of more devices. Or you may find that it is an optional extra that is charged for separately.

Similarly you may find that the hotel’s Internet service underperforms during peak occupancy especially when many guests are streaming online multimedia content like Netflix concurrently.

Some of us may see this as a deal-maker or deal-breaker when it comes to booking that accommodation facility depending on what level of priority we give to Internet access while on the road. It may be more important when we engage in videocalling as a way to “touch base”, upload photos to an online album or social media, or enjoy online video content during the evening. As well, it can be of concern where multiple people like a family are using the connection concurrently.

The venue may also see your interest in its guest-access Internet as a way to improve their offering especially when they are in a position to “re-contract” their Internet service to a better tariff. If they are in a truly-competitive market, they could easily end up placing the service on a tariff that offers a “better bang for the buck”. This is by offering more bandwidth and data usage (where applicable) for the same amount that they previously paid or for less.

As well, it may appeal to rental-premises owners who want to see value in renting out their short-let venue for longer periods at a time. It can also help them to court the business community who may use these places as a base to stay while doing business in the local area.

It is still worth it to raise questions about the Internet service you may end up with while on the road. This is because it can benefit both you and the venue owner in various ways.
