If you have owned a Nikon digital camera, you may have dealt with the Ultra Accessory Connector (UAC) as a method to tether your camera to your computer for, perhaps, downloading. This would typically be facilitated using a USB to UAC cable that came in the box with your camera.
Apple is resurrecting this connector as part of its MFi (Made For iOS) accessories program for iOS devices. There was a lot of confusion in the computing press regarding this connector because it could be about a different socket existing on a subsequent iPhone or iPad, or devices and accessories not working unless “you get with the program” – be part of the Apple ecosystem.
But the Ultra Accessory Connector is about how its use as an intermediary or accessory-side connector on a pair of headphones. It is being called on because an increasing number of newer smartphones and ultraportable laptops won’t be equipped with the traditional 3.5mm headset jack where you can connect a wired headset.
There is also the same appeal where headphones will have integral digital-analogue audio circuitry and there has to he a way to connect these to your smartphone if you are going the “wired” path. It is something very familiar to those of us who use a USB headset with our computers or a Bluetooth headset or audio adaptor with our smartphones. Here, manufacturers will see better digital-analogue circuitry and / or sound-processing technology such as microphone arrays, accessory-side sound-tuning and active noise cancellation as a way to differentiate their product ranges more effectively and innovate their products.
It will still be feasible to keep a level playing field for headphones that use USB or other wired digital links.
The approach that is being pushed here is for a headset or pair of headphones to have the UAC connection as an accessory-side connection. Typically this will be as a “lump” on the headphone cable like what is used for remote control or a microphone, which comes apart. On the other hand, the most probable implementation for a pair of traditionally-styled “cans” would be a socket installed on one of the earcups similar to what happens for detachable-cord implementations. The headset would then be supplied with one or more application-specific connection cables that have a UAC-connector on the accessory side and the appropriate connector (Apple Lightning, USB-A, USB-C or 3.5mm phone plug) on the equipment side. There is also a goal to have such cables also available through the aftermarket thanks to accessory suppliers like Belkin.
The UAC connection is meant to facilitate a digital connection that works with USB or Apple Lightning norms along with the standard stereo analogue connection. Here, it means that an accessory cable can exist which has the traditional 3.5mm phone plug on it to allow use with equipment that still maintains this connection. This includes still being able to use the 6.35mm headphone jack adaptor to connect your headpbones to hi-fi equipment or the two-pin airline adaptor to plug in to your aeroplane seat’s in-flight-entertainment connection. It also encompasses the goal with the Apple Lightning and USB-C standards to provide analogue pass-through from equipment-side digital-analogue circuitry to cater for the cheaper headset designs.
In the digital context, this can mean that the sound processing circuitry can present itself to Apple’s iOS devices or “open-frame” USB Audio implementations properly as the equipment expects. Apple still sees this as being important because their newer MacBook laptops are being equipped just with USB-C connections and MacOS is still providing class-driver support for USB-Audio devices. But most other regular-computer and mobile operating systems are providing a similar level of support for USB Audio.
But what needs to happen in both camps is for proper operating-system-level support for audio input and output in both the communications and multimedia contexts, along with accessory-side remote control for call management, media transport control and volume control at least. It may also include the ability to use a basic display on the accessory to show information like current time, incoming calls and messages and media-play details, something that can earn its keep with in-line remote-control accessories.
The UAC connection type can lead to the idea of “feature modules” or “enhancement modules” that add extra functionality to or improve the sound quality of existing UAC headphones. For example, they could offer:
a highly-strung DAC circuit as an upgrade path for better sound quality with premium headphones;
a Bluetooth adaptor to add Bluetooth wireless functionality to a set of existing wired “cans”;
an advanced remote control with display so you can keep your device in your pocket;
or an extended-power module which allows you to use external battery packs to obtain long operating times out of your smartphone and advanced headset.
What the UAC connector that Apple is pushing for is the ability to headset manufacturers to continue to work on feature headsets that can work across all of the computing platforms. As well, I also see the UAC connector as a pathway to innovation because manufacturers will be encouraged to work on features that work across all phone platforms. This is more so as we invest in the premium headsets to go with our smartphones and computers so we can listen to music or watch those videos while we are on the train.
A very dominant usage case being highlighted for laptops and 2-in-1 computers is the creation of a fully-fledged workstation at your main workspace or game-playing space. This involves connecting the portable computer to at least one larger-sized screen along with a desktop-grade full-size keyboard and mouse. Such workstations may even be the place where you connect extra non-portable storage devices like USB hard disks or optical drives or connect to your network via a blue Ethernet cable rather than the Wi-Fi wireless connection for improved reliability.
USB Type-C or Thunderbolt 3 ports will be seen as the way to connect expansion docks, peripherals and the like to your laptop
The USB-C connector and its higher-speed variant, the Thunderbolt 3 connector have been valued as a way to provide a single-cable connection option between your laptop and the normally-sessile peripherals once you used an expansion module, commonly known as a docking station or dock. Here, you would connect all the peripherals to this expansion module then connect your laptop computer to that same device via USB-C or Thunderbolt. This is also underscored by a significant number of these devices being equipped with USB Power Delivery to power the portable computer from that same device, underscoring that “one cable to connect” goal.
Let’s not forget that some manufacturers are integrating this “dock” functionality in to some of their display monitors so that these screens are where you can connect your keyboard, mouse and external hard disk.
Lenovo had pitched the ThinkVision P24h and P27h monitors which have a qHD (2560×1440) display resolution and an sRGB high colour gamut “out of the box”. These monitors, with the super-narrow bezel, implement a USB-C connection to the host computer facilitating a DisplayPort 1.2 connection, the data connection, and a Power Delivery connection with a power budget of 45W, along with a four-port self-powered USB hub.
LG’s 32″ 4K monitor with HDR10
LG had teased a 32” 4K monitor which has the narrow bezel and can handle HDR10 video but also offer this similar USB-C connectivity and USB hub. They also tweaked the monitor’s integral speakers for that bit of extra “kick” from the bass. They also are pleasing the gamer clans by offering the UltraFine 34” 5K and 4K UHD gaming monitors with features like AMD’s FreeSync technology and 1ms motion-blur reduction.
Dell had advanced a range of monitors including the UltraSharp 32” 8K UHD model and the 27” Ultrathin monitor which has its electronics housed in its base. This monitor implements USB-C connectivity to the host along with a QHD display.
It’s not 4K resolution in this Dell 32″ monitor, it is 8K resolution
They even advanced the 24” Touch monitor with an integral 10-point touchscreen along with the 24” Video Conferencing Monitor which has an integral Full-HD IR Webcam that has a privacy shutter. This monitor’s camera also adds on support for facial-recognition login under Windows Hello while the sound is catered for with a pair of 5-watt speakers and a noise-cancelling microphone built in.
Dell’s slimline 27″ monitor with its electronics in its base
Even households aren’t left out with a range of monitors from Dell that are designed with aesthetics and high-grade on-screen experiences. For example, the Dell 24 and 27 monitors (S2418HX / S2718HX) implement the ultra-narrow-bezel design being implemented in most of Dell’s laptops and all-in-ones plus the ability to support HDR along with Waves.Maxx sound tuning.
For those of us who have a screen that currently “ticks the boxes” for our computing experience at our desks, most of the manufacturers are offering highly-capable Thunderbolt 3 and USB-C docks. Remember that you can daisy-chain 6 Thunderbolt-3 peripherals from the same Thunderbolt-3 bus, which can open up a range of possibilities.
For example, Lenovo and Dell are offering these expansion modules as part of their official accessory lineups. Lenovo’s contribution is in the form of the ThinkPad Thunderbolt 3 dock (US279) with video connectivity in the form of 2 DisplayPort, HDMI and VGA ports; 5 USB 3.0 ports; audio jack for those speakers; a Gigabit Ethernet port; and USB Power Delivery for the host computer with a power budget of 60 watts. There is a USB-C variant that offers similar functionality for computers not equipped with Thunderbolt 3 connectivity. But Belkin have previewed the Thunderbolt 3 version of their original Thunderbolt 2 Express Dock, which will have 3 USB-3 connections, 2 Thunderbolt 3 / USB-C connections, two audio connections, a DisplayPort video connection and a Gigabit Ethernet connection. This device can supply a USB Power Deliver power-demand of 85 watts, again reducing the need for extra power supplies for your computer.
In the last post I wrote about CES 2017, I had cited Zotac’s external “card-cage” graphics module which uses Thunderbolt 3 connectivity as a way to enhance their “midget PC” product. This isn’t the only product of its kind to appear at this show. MSI also premiered the GUS (Graphics Upgrade System) “card-cage” external GPU system. This is styled for gaming and is a refresh of their original GUS external graphics module that they launched in 2012, but implementing the Thunderbolt 3 standard. It has a 500W power supply and USB 3.0 Type-C and Type-A connections.
Beyond the docking stations or, should I say, expansion modules, there have been a few other computer accessories with one being of note in the form of a Kingston 2Tb USB thumb drive.
The home network
A key trend affecting the home network this year at the CES 2017 is the concept of distributed Wi-Fi wireless systems. This consists of kits that use multiple devices to spread the Wi-Fi network’s coverage over a large area. They have appeared because most householders have run in to issues with their home network’s Wi-Fi wireless segment not providing reliable wireless coverage everywhere in their house.
They are typically based on a single chipset and most of them implement a dedicated wireless backhaul between the slave devices and the master access point. A significant number of these devices implement a “mesh” topology where there is a “root” node that works as a router along with multiple access point “nodes” that connect with each other and the “root” node to provide Wi-Fi coverage, using multiple backhaul connections for load-balancing, fail-safe operation and increased bandwidth. Other systems implement the traditional router and range-extender method with a single upstream connection but have a simplified setup method and properly-simple roaming between the access points.
The problem with these systems is that you have to use equipment that is offered by the manufacturer as part of that same system. This means that there isn’t any of the interoperability available which, at the moment, is stifling innovation.
Qualcomm launched their Wi-Fi mesh chipsets which can implement Bluetooth, CSRMesh and Zigbee also to support the “Internet Of Things”. The software is based also around a dedicated software framework and cloud-services. But these systems also support wired backhauls and multiple-hop mesh setups.
D-Link Covr router and wireless extender package
D-Link had premiered the Covr distributed Wi-Fi system which consists of a router and a wireless extender that implements the automatic setup and simplified roaming. For those of us with existing home networks, they also offered a Covr HomePlug system consisting of two wireless access points linked by a HomePlug AV2 powerline backbone. Another example that purely uses a Wi-Fi backbone is the NETGEAR Orbi which implements a router and a satellite extender device.
On the other hand, Linksys provided a true-mesh setup in the form of the Velop Wi-Fi system that implements multiple nodes. The Velop system even is able to work with Amazon’s Alexa voice assistant such as controlling the guest Wi-Fi network or asking Alexa to quote your network’s credentials. Click or tap on this link to see a Linksys YouTube video which explains what Velop is about if you can’t see it below.
As well, Linksys have launched the WRT32X Gaming Router which implements the Rivet Networks Killer Wi-Fi chipset similar to what is implemented in the Dell XPS 13 Kaby Lake Ultrabook. Here, it is optimised to work with client devices that implement the Rivet Networks Killer chipsets but is a 3×3 802.11ac MU-MIMO system that supports 160kHz bandwidth. There is also the EA8300 Max-Stream AC2200 Tri-band MU-MIMO Gigabit Router which is a more affordable device based on a 2×2 802.11ac three-radio design. Both these routers are equipped with Gigabit Ethernet for LAN and WAN (Internet) connections.
Linksys even offered a WUSB400M dual-band MU-MIMO 802.11ac USB wireless network adaptor as a way to retrofit your existing laptop or desktop computer for the new-spec Wi-Fi segments. This network adaptor connects to the host computer via USB 3.0 and can work at a 2×2 AC1200 setup.
What Linksys have been offering is a representative of another trend affecting the home network’s Wi-Fi segment where Wi-Fi network infrastructure hardware is working on a simultaneous three-band approach, operating on the 2.4GHz, 5.0GHz and 5.8GHz wavebands at the same time. As well, Wi-Fi repeaters are even being setup to implement the 5GHz bands as the preferred backhaul. Amped Wireless is another company also offering the three-band Wi-Fi network-infrastructure equipment in the form of a router and an extender.
NETGEAR Nighthawk S8000 Gaming And Media Switch – for the home network or home entertainment unit
NETGEAR’s not silent here with the Nighthawk S8000 Media Switch which is a media-optimised Ethernet switch implementing some of the quality-of-service technologies in their managed switches but optimised for household use. As well, this house-friendly switch can support functions like link-aggregation for increased throughput on supported devices like desktop computers and NAS units with two Gigabit Ethernet connections supporting this mode.
This is also intended to complement the Nighthawk X10 gaming and media router which has an integrated Plex Media Server for USB Mass-Storage devices connected to this router’s USB ports. It is also one of the first few home routers to offer 802.11ad WiGig (60GHz) same-room wireless network LAN segment capable of a throughput three times that of the fastest 802.11ac Wi-Fi network; along with the 802.11ac 4×4 MU-MIMO three-band Wi-Fi wireless LAN segment.
As well, there are 8 Gigabit Ethernet ports which can also support port-trunking for failover or high-throughput operation like the Nighthawk S8000 switch along with the WAN (Internet) side being looked after by a Gigabit Ethernet connection. The processing horsepower in this performance router is looked after by a 1.7GHz four-core CPU and it can support VLAN setups of the port or 802.1q tag variety.
Both these devices are pitched at “core” online and VR gaming enthusiasts with those hotted-up gaming rigs along with people who are in to streaming 4K ultra-high-definition TV content. But they can also earn their keep with those of us who run our businesses from home and want “big-business-grade” connectivity for IP-based communications or cloud computing.
Another trend that is surfacing is security-optimised broadband routers for the home network. These offer the “unified threat management” abilities associated with business-grade Internet setups but in a manner that appeals to the ordinary household. The latest from this class of network-Internet “edge” device is the Norton Core router. This device implements content-filtering and security software that is also focused towards the Internet-of-Things devices in your household due to the increased awareness of security risks and poor software maintenance practices associated with these devices.
The self-updating router works with Symantec’s DNS service to prevent DNS hijacks as well as implementing deep-packet inspection on unencrypted traffic to screen for malware and network intrusions. As for encrypted traffic, the Norton Core router will inspect packet headers for and connections of this traffic class. It also comes with Norton Core Security Plus endpoint-protection software which is a variant of the business-grade Security Premium endpoint software and can be run on 20 devices running either Windows, MacOS, iOS or Android but the router is dependent on this endpoint software for the full protection..
Lenovo Smart Storage home NAS
Most of the network-attached-storage units were focused on the “personal cloud” trend with the device being the centre of your data-storage universe while software and services work to locate these devices from afar. Similarly, some of them are using rich media servers which can do things like obtain further data about your media content. One of these devices is one that Lenovo launched called the Smart Storage 6Tb NAS which implements facial image recognition along with event-driven recognition to make it easier to identify and organise pictures of people just like what Facebook and Windows Photo Gallery were about. This unit has 802.11ac 2×2 Wi-Fi for portable use but can be connected to your home network via an Ethernet cable.
The next article about the 2017 CES will be highlighting the trends affecting home entertainment including the new smart TVs that will be showing up.
I am reviewing the Dell AE2 Performance USB Headset which is a USB-connected gaming headset designed by SteelSeries on behalf of Dell.
This is a practice that a lot of manufacturers, distributors and retailers in the computing and consumer-electronics game have been involved in where they ask someone else to design and make the product to be sold under the client’s name. Infact, most of the Japanese consumer-electronics names had engaged in the practice themselves, either making “white-label” products for other companies to sell under their own labels or being the companies who called on others to design and build products.
One of the ways you would know that this headset was a SteelSeries design was the speaker cloth on the earcups had the label “Acoustics by SteelSeries” written on it. As well, I had a look through the product documentation and it required me to install the SteelSeries Engine software to be installed on my computer so I could gain more control over the headset.
applies to circum-aural or supra-aural designs
Primary sound path
Microphone integrated in left earcup
Active Noise Cancellation
Connection for main operation
USB Audio via Type-A
The headset itself
The Dell AE2 Performance USB Headset is designed like most circum-aural headsets and implements the USB bus as its way of connecting to host devices. As to appeal to the gaming community, each earcup has a glowing white ring which illuminates when you have the headphones plugged in to your computer. But, as I have said later on in the review, you can determine whether this glowing occurs or not or what colour is used thanks to a configuration program called SteelSeries Engine.
I have done most of the reviewing of this headset without using the SteelSeries Engine control software, which would represent requirements where you can’t or don’t want to add extra software to your computer to gain more out of these headphones.
Connectivity and Functionality
How the Dell AE2 headset connects to your computer
The Dell AE2 Performance Headset connects to USB-equipped computing devices using its USB Type-A connector and presents itself to them as a USB Audio input and output device. Windows 10 was able to even identify this headset as headphones and give this device priority over existing default audio devices like integrated speakers in a monitor or laptop. The headset has a maximum rated power draw of 150mA which means it shouldn’t place much demand on your laptop’s battery power as well as being able to work comfortably on a four-port bus-powered USB hub being used by input devices.
I had tried using this headset with my Samsung Galaxy Note 4 Android smartphone by connecting it to the phone via a USB OTG cable. Here, it would work as a USB Audio device but I had found that this functionality didn’t extend to communications tasks like using the phone. Here, I would communicate with the caller via the smartphone’s speaker and microphone rather than through the Dell USB headset. The USB-based audio device as a mobile-phone accessory is becoming a reality thanks to USB Type-C connectivity and manufacturers doing away with the 3.5mm audio jack on their phones.
You can run the SteelSeries Engine 3 software on your Windows or Macintosh computer, which effectively allows you to gain more control over the headset. This program offers a DTS Headphone 7.1 surround decoder for headphone applications, a five-band graphic equaliser, a microphone-optimisation program along with the ability to control the lights on the earcups. You could even have the lighting change colour based on games events which works for some games thanks to API hooks that SteelSeries have published for game studios to use.
This program works properly as advertised and you don’t need to have it running all the time you use the headphones, which can be a boon for those of us who use laptops while on battery power.
SteelSeries design highlighted in earcups
These headphones are very comfortable to wear for a significant amount of time thanks to the circum-aural design and the fact that your ears are not touching anything hard. As well, they don’t feel sticky after that long time of use because of assuring some airflow around the foam surrounds.
The Dell AE2 Performance USB Headset is able to handle music in a similar manner to most circum-aural headphones by being able to put up some good bass response. It was also able to work well with the vocals and other instruments but you may experience a bit of reduction of higher frequencies – it is not really something with hi-fi credentials for listening to detailed music.
Glowing ring on earcups
I have also tried these headphones with some video content in the form of watching an Inspector Morse episode (Sins Of The Fathers) from a DVD using my desktop computer. Here, the dialogue came across very clearly and I was able to hear the sound effects distinctly with the added bass response doing some justice to certain effects like the rumbling heard in the brewery that was part of the story. There were a few brewery scenes in that same show which represented a sound presentation not dissimilar from what would be expected from a lot of action-based computer games with people traipsing around the factory, the rumbling of machinery and the music score, with the Dell AE2 Performance USB Headset handling them very well.
I had placed a call using Skype to someone I know and they had noticed that I was able to come across very clearly with the headset while I was able to hear them very clearly. The Dell AE2 headset can earn its keep as a communications headset for VoIP softphones and similar online calling platforms, especially if they implement high-quality voice codecs.
Noise Reduction and handling of noisy environments
The Dell AE2 headset offers a significant amount of noise reduction which can be a boon for those of us who are commuting or working in a noisy office. It may not be as effective as active noise cancellation but can suit most of us in these environments.
Limitations and Points Of Improvement
One of the problems that will need to be answered with these USB headsets is for all mobile operating systems to treat them as headsets when they are connected to mobile devices.
Another desirable feature would be to have a hardware switch on the headset that turns the lighting on and off so you can be able to reduce your laptop’s battery drain when you run them and avoid the need to run a configuration program to achieve this goal. As well, headsets of this kind could benefit from a volume control on the earcups that controls the host system’s volume using the standard USB protocols.
Similarly, Dell and SteelSeries could implement a USB Type-C detachable connection so that they can be provided with a detachable cable allowing them to last longer by allowing you to replace damaged cables. This would also cater towards the newer USB Type-C direction as more of the computers come with this connection.
Personally, I would position the Dell AE2 Performance USB Headset more as suitable as a general-purpose computer headset for applications where you want to hear your computer software’s audio privately but are not expecting to pay attention to how music comes across through them. This is rather than just as something for chatting during games or hearing games effects privately and intensely.
The Dell AE2 Performance USB Headset also represents a newer trend for headphone construction where there is emphasis on “digital to the earpiece”, which can open up many points of innovation like optimised sound or active noise cancellation. The USB connectivity allows for this to work for wired-headset setups including allowing the host device to actually power the headset.
Previously, the USB standard has become effectively a “DC power supply” standard for smartphones and tablets. This has avoided the need to end up with a desk drawer full of power supplies and battery chargers with the associated question of which one works with which device. It has also led to various points of innovation like USB external battery packs and multiple-outlet USB “charging bars”. Similarly, gadgets like lights, fans and cup warmers have also appeared that can be powered from a computer’s USB port or a USB charger.
There was also the environmental view that we will see less chargers destined to landfill when devices are finally retired or less need to supply chargers with mobile phones. But a common reality is that most of these USB chargers end up being kept near or plugged into power outlets around the house more as a way of allowing “convenience charging” for our gadgets.
But the problem has surface where particular USB chargers don’t do the job properly when charging particular devices, especially high-end smartphones or tablets. Here, you need to be sure that you use something like a 2.1A charger for these devices and have them connected using a cable known to work.
The new USB Type-C standard is bring this concept as a low-profile connection for newer smartphones along with using the USB Power Delivery standard to extend this convenience to larger tablets and laptops. But there have been situations where substandard USB Type-C leads and chargers have been appearing on the market placing our new gadgets at risk of damage due to them being improperly powered.
Now the USB Implementers Forum have brought forward a certification program for USB Type-C chargers and leads with this program augmented by a logo. What will happen is that a charger or external battery pack will have to show this logo and state its power capacity in watts so you can be sure it will charge your Ultrabook or 2-in-1 as well as your smartphone.
What should be required is that the logo and the power output is stamped on the charger body itself and also a colour code is standardised for the power output. Having such a colour code could be useful when recognising which charger from a bunch of chargers could handle your gadget or which one is the right one to buy when you look at that display rack.
At least something is being done to make it easier to be sure we end up with the right USB Type-C power-supply device for that 2-in-1 Ultrabook or smartphone without the risk of the computer not charging or being damaged.
I had come across in my email a Kogan ad where they were offering a highly-capable USB dock with integrated video support for 2 displays. Here, they are offering the product for AUD$120 including tax but excluding shipping.
This device has 2 USB 3.0 ports and 4 USB 2.0 ports, which can come in handy with a mix of USB input devices and USB storage devices along with an integrated USB sound module and USB-Gigabit-Ethernet network adaptor.
For video, there is a DVI connection and an HDMI connection for displays that work to DVI or HDMI specifications. From the manufacturer’s site, there is also meant to be a DVI-VGA adaptor so you can use it with that VGA-only display or projector. This functionality is supported according to Displaylink standards for USB-video adaptors.
It is targeted at laptop users who use current-spec laptops but want to maintain a desktop workspace with “full-bore” peripherals like full-sized input devices or larger monitors, let alone a reliable Ethernet or HomePlug AV500 connection to the network. Here, the idea is that a person who uses a “work-home” laptop can quickly connect and disconnect the laptop to and from this expansion module using one plug while all the peripherals are in place, connected to this device.
In some cases, it can also be of benefit to those of us who use small desktop computers like all-in-ones or “Next Unit Of Computing” devices where there isn’t much in the way of connectivity; or for those of us who carry around a laptop that doesn’t have much in the way of external-device connectivity but don’t want to worry about losing adaptors left right and centre when you move from place to place.
In the early 1980s, an electronics company tried out a common application for bone-conductivity personal audio technology by selling to a mail-order gadget-supply company and to Radio Shack (Tandy) an AM/FM stereo headphone radio that implemented this technology. This radio, known as the “Bone Fone” and powered by 4 AA batteries, dropped around your neck like a shawl and used bone-conductivity technology to bring your favourite broadcast’s audio to your ears. You were able to hear your music privately through the sound being transduced through your neck clavicle bone to your ears.
It was found to be heavy but the technology has resurfaced in another application that would be seen to be popular. This time it is a pair of sunglasses that use an integrated Bluetooth headset that exploits this technology. These Zungle Panther sunglasses, modelled on the Oakley Frogskins, don’t require you to wear headphones or an earbud to hear your music or caller due to this technology. Rather they use your skull bone as the transducing surface.
These glasses link to your smartphone using Bluetooth 4.1 technology as a way to save battery runtime for both devices. They also implement a jog wheel to allow you to control audio playback as well as implementing a noise-cancelling microphone when you make and take calls or ask something of Siri, Google Now or Cortana.
For their power, the bone-conducting Zungle Panther glasses implement a 300mAh battery that uses the same microUSB charging connectivity as most of the current Bluetooth headsets.
Because of what they do, they may be considered to be bulky like a set of 3D glasses used for watching a 3D movie at the cinema but they weigh in at 45g. They were found to earn their keep for cyclists and other road users who want to keep their ears open to hear for traffic.
There is actually a Kickstarter campaign to get the bone-conductivity glasses idea off the ground with a starting price of US$99.
Lenovo Yoga 900 – can benefit from the Minix Neo-C USB-C Multiport Adaptor
Minix, a computer manufacturer based in Hong Kong, has released a USB Type-C expansion module that has the same calibre as most of the current-issue ultraportable computers that it is targeted for.
The Minix Neo-C USB-C Multiport Adaptor has a high-quality metal finish to complement the Apple MacBook 12, the latest HP Spectre and most of the high-end Ultrabooks and 2-in-1s that have the USB Type-C connector. There are three different finishes available to match the finishes that the MacBook 12 is available in – a “space grey”, silver or gold finish.
Available with HDMI for the current and latest displays
It has 2 USB 3.0 Type-A connections along with a card reader for SD and microSD memory cards which come in handy with your Android mobile phone or digital camera’s “film”.
.. or VGA for older displays and projectors
There is also a Gigabit Ethernet socket so that you can connect your ultraportable to a wired Cat5 Ethernet or HomePlug powerline network. But this requires you to download and install a software driver for the network-adaptor functionality to work – the operating-system vendors and the USB-IF need to define a class driver for network adaptors.
The device comes in two variants – one with a VGA connector that works to Full HD resolution and can earn its keep with that economy data projector; and one with an HDMI connector that works to 4K HDR resolution which I would consider more “future proof”. Of course, you can connect your ultraportable’s charger or a USB-C peripheral to the USB-C socket on this expansion module.
You can connect your Ethernet or HomePlug network to your laptop here
You have to connect your laptop’s USB-C charger to this device rather than run it just from your laptop if you are using it to connect a large USB storage device like a USB hard disk or USB optical drive to that laptop.
One of the use cases that Minix were pitching included the ability to fill in your ultraportable’s missing functions and connections. This is important where an increasing number of these computers omit connections like USB Type-A ports, video ports or SD card slots in order to preserve their slimline look and lightweight build. In some cases, your computer may have an SD card slot but it may have malfunctioned and you still need SD-card capabilities for something like your digital camera. The small size and lightweight design of this expansion dock may allow you to stuff it in your briefcase.
Another use case that has been highlighted is using the Minix Neo-C as part of creating your “primary” workstation at your home or your office. It is a practice that I have noticed a lot of people do when they want to use a laptop or ultraportable computer as their main or sole “regular-platform” computer. Here, you connect a full-size keyboard, mouse, large monitor and, perhaps, a USB external hard disk or optical drive to the laptop computer and set up a dual-screen computing arrangement when you work at that workstation. This device simplifies the connectivity procedure and requirements down to one cable that you connect and disconnect from your laptop computer while all the peripherals are connected to the expansion dock.
There are a few reasons why I like the Minix Neo-C USB-C expansion dock. One of these is that it is presented in a manner that complements all of the current-issue premium ultraportable computers. This is more so where the manufacturers are placing equal importance on the looks of these computers to convey the position that these computers are pitched for. Another of these is that it has enough connectors to suit most applications whether to deal with the MacBook 12 that has no other connections or to provide extra connectivity for computers that already have other connections. Similarly the small size can go well for those of us who want to have a small expansion dock in our laptop bag or briefcase to connect to an external monitor or wired network segment or add that USB peripheral.
Belkin have launched a USB-C car charger that can charge up one of the newer smartphones, tablets or ultraportable laptops that are powered through the USB Type-C connector, which is becoming the trend for today’s portable computing equipment. This also comes in handy if a passenger wants to use that tablet or 2-in-1 during that car journey without compromising the device’s battery runtime. Think of activities like being on the Internet or even viewing online video material to while away the journey would be considered risky for your 2-in-1’s battery.
One may think that the Belkin USB-C car charger that plugs in to the cigar-lighter socket in the car and sells for US$50 is too expensive for this class of device but there is more to it to assure that the device it is connected to is properly and safely powered so it lasts a long time.
This car charger implements advanced universal-supply circuitry to stabilise its output current, which prevents the power surges associated with starting up the engine from getting to the equipment it supplies. As well, this circuitry matches the power supply to the equipment’s needs to prevent any risk of damage the that equipment.
It is also compliant to USB-PD to assure proper power supply to one of the new smartphones, tablets or ultraportable computers and can supply a load of up to 27 watts. The requirement for power supplies and cables to be compliant to this standard has come about because of the market’s awareness of substandard USB cables and power supplies placing the expensive personal-computing and communications devices we have at risk of damage. Here, Amazon have tightened their rules regarding the purchasing of USB accessories where they won’t procure these accessories for sale through their channels unless they are certified compliant by USB-IF.
The supplied cable which has a USB Type-C connector on each end has a length of 4 feet or 1.2 metres which would reach from the dashboard to the back seat of most cars or the first row of seats in a vehicle with multiple rows of seats. Of course, you could use it with existing smartphones and tablets when you use a USB Type-C adaptor cable – a USB-C to Micro USB cable for most Android and Windows devices or a USB-C to female USB-A cable along with an Apple Lightning cable or an Apple USB-C to Lightning cable for your iOS devices.
This USB-C car adaptor could earn its keep with powering or charging the newly-released portable computing equipment on a long journey so you have enough power to use it at the destination.
Increasingly Google is encouraging companies involved in consumer audio-video to integrate Google Chromecast audio or video functionality in to their devices. This avoids the need to purchase and install a Chromecast dongle to benefit from audio and video streaming from online services.
Sonifi brought this concept in to the hotel scene so you can lie on your hotel-room bed and watch Netflix managed by your Android phone while Vizio, Sony and Philips are implementing it in to their TVs. Google even implements this concept in to their Google Fiber TV set-top boxes so that you don’t need a Chromecast dongle for this functionality. But Vizio has taken things further with Google Cast for Audio by offering this functionality in their latest range of sound bars.
Typically, you may think that a company may offer this function just to one soundbar or speaker base in their lineup but Vizio has offered it across the board for their up-and-coming SmartCast soundbars. These will work as Google Cast Audio devices where they can play online audio sources like Pandora or Spotify rather than being a “soundbar + Chromecast” device that adds Chromecast to your TV.
One article sees these soundbars as an answer to the Sonos multi-room sound system and nothing is further from the truth thanks to Google’s latest Chromecast software. Here, you could gang these speakers together in a “party mode” or have them playing different programs in a similar way to what you can do with Sonos. Let’s not forget that you can have something like Spotify or Pandora playing and the music isn’t interrupted if a call comes in or one of your phone’s apps throws a notification signal. It also means that the ringtone or the notification sounds don’t blast through your Google Cast setup’s speakers.
As for the price, the cheapest unit, which is a 38” 3.0 setup costs US$180 while the most expensive models being the 45” 5.1 setup that comes with surround speakers and a slim subwoofer runs for US$500.
Who knows who will launch the first stereo or home-theatre receiver or stereo system that has integral Google Cast functionality or if an existing multiroom audio platform will end up with Google Cast integrated in to it.
You could be soon able to equip your existing laptop or 2-in-1 with the same kind of fingerprint scanner as the Lenovo ThinkPad Helix 2
An increasing number of business-focused Windows laptops are being made ready for Windows Hello which is the password-free login ability that Windows 10 offers. This allows for facial recognition or fingerprint recognition as an alternative to keying in that Windows password.
But what if you have that tower desktop, all-in-one or existing laptop that has no RealSense camera or fingerprint reader. Normally, you would think that you were cut out of this feature.
At the Computex 2016 “geek-fest” in Taiwan, there were two aftermarket USB accessories that bless these computers with Windows Hello login abilities. One of these is a webcam that is compliant to Intel RealSense specifications which opens up the path for facial recognition, while another of these is a USB fingerprint-reader dongle that is very similar to a Bluetooth or wireless-peripheral-transceiver dongle and plugs in to the side of a laptop computer.
These peripherals would be a step in the right direction for small businesses and consumers if they were sold at reasonable prices and were made available at most electrical stores, computer stores and the like, rather than just being sold to value-added resellers that cater to big businesses.
A solution I would like to see especially for desktop users or people who set up primary workstations would be a fingerprint reader integrated in to a keyboard or mouse. This could be offered as a differentiating feature for business and gaming peripherals. Similarly, a standalone desktop fingerprint reader could be offered as a way to have your existing workstation or “gaming rig” working with Windows Hello. Similarly, a fingerprint reader could be offered as a “short-form” device that can be integrated in to the PC cases that tend to modified by gaming enthusiasts.
Similarly, more manufacturers and resellers could contribute to this class of device in order to allow more of us to benefit from Windows Hello.
