Jen Costillo of Lab 126 discusses the Android sensor subsystem at the Android Builder Summit in February 2012. Abstract: This lecture will arm Android device architects with the tactical knowledge they need to navigate the Android Sensor subsystem and make knowledgeable design choices to improve user experience and improve battery performance. The talk will address: Hardware architecture and trade-offs including latency, power, and software architecture implications: Wake up events and power considerations Gesture Detection Algorithm processing location and considerations Testing methodologies (Creating tools to aid develop and collect data. This talk targets the kernel/firmware developer responsible for the sensor architecture. They should be familiar with kernel drivers, embedded systems, hardware bring up, Android services, and the C language. You can also download the presentation slides on linuxfoundation.org website.

Bump In Host on Android – IPv4 to IPv6 Translation – Android Builder Summit
Yonghui Wang, representative of China Mobile to the Linux Foundation, gives a presentation about BIH (Bump in the Host) protocol at the Android Builder Summit in February 2012. Abstract: BIH or Bump-in-the-host realizes a host-based IPv4 to IPv6 protocol translation mechanism that allows a class of IPv4-only applications that work through NATs to communicate with IPv6-only peers on Android. The host on which applications are running may be connected to IPv6-only or dual-stack access networks. BIH hides IPv6 and makes the IPv4-only applications think they are talking with IPv4 peers by local synthesis of IPv4 addresses. China Mobile has released an open source implementation of the protocol. The presentation slides has not available for this talk. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.

Shenzhen Wabook EPC1029 ARM Netbook Runs Android 2.3 / 4.0
Shenzhen Wabook Technology, a manufacturer with a factory based in Zhuhai, China, showcases their Wabook Netbook at Cebit 2012. The Wabook EPC1029 is a netbook running Android 2.3 (upgradable to Android 4.0) on a Rockchip RK2918 (ARM Cortex A8) @ 1.0 GHz. The device features a 10.1″ TFT LED display (16:9 aspect ratio) with a resolution of 1024×600, 3 USB host ports, Ethernet. No other technical specs are available yet. Only Android is available, but it might be possible to hack Ubuntu or another distro to run on it. You can watch the video below by Charbax of armdevices.net to see the device. Don’t worry pink is not the only color as white and black are also available. The price for 1,000 pieces (MOQ) is 93 USD and it takes around 25-30 days to get your order. They have already sold tens of thousands to a company in France. With […]
Huawei M2M Solutions: Android Rear-View Mirror, Smart Grid and more
Huawei is exhibiting their Machine to Machine (M2M) solutions at Cebit 2012 until March 10, 2012. They are showcasing Smart Meter solutions with home energy gateways, smart gas meters, smart electric meters, in-home displays.. all communicating via Zigbee. Their solution is currently being implement in the UK market. They are also exhibiting diverse modules (mainly based on Freescale i.MX5 processor) featuring Huawei 3G technology that could be used in tablets among other things. But the thing is really found interesting was their M2M solutions for the auto industry especially the Android car rear-view mirror where you can have the left half of the rear-view mirror displaying a menu so that you can access apps such as GPS maps, control your music or your phone and see information about your car. Here are some details above this rear-view mirror: Samsung SP5V210 Cortex A8 Processor 4.3″ TFT capacitive touchscreen – Resolution: 800×480 […]
Valueplus Tizzbird Stick N1: Android 4.0 HDMI/USB Media Player Dongle
Valueplus, a Korean company specialized in “media application products”, is currently showcasing the Valueplus Tizzbird N1 at CeBit 2012, in Hanover, Germany on March 6-10 2012.

The device also has built-in Wifi 802.11n for network connectivity. The way it works is you plug the stick into the HDMI port of your TV […]
Samsung Exynos 5250 Dual-core Cortex A15 and GAIA SMDK Development Board
Samsung showcased its new Exynos 5250 Dual-core Cortex A15 processor at Mobile World Congress as well as the corresponding Samsung Exynos 5 GAIA SMDK Development board. Announced in November 2011, the new Samsung Exynos 5250 processor features 2 Cortex A15 clocked at 1.7 GHz or 2 GHz, with a Mali-T604 GPU and support for dual-channel 800 MHz LPDDR3 RAM that allows for a data bandwidth of up to 12.8 GB/s. The processor is manufactured using 32-nm HKMG (High-K Metal Gate) technology that reduces leakage by 30% proving lower power consumption. Samsung claims the new Exynos 5 processors are twice as fast and consume twice as less power than its previous Exynos 4 application processor based on Cortex A9. This seems to confirm TI OMAP 5 vs. Nvidia Tegra 3 benchmark results. The Exynos 5250 supports embedded DisplayPort (eDP) interface up to WQXGA resolution (2560×1600), which is handy for Samsung since […]
Microsoft Unveils Windows 8 Consumer Preview at MWC 2012
Earlier this month, Microsoft announced they would be releasing Windows 8 Consumer Preview at the end of February, and they have done so yesterday with an official announcement at Mobile World Congress 2012, in Barcelona, Spain. During the event, they showcased ARM tablets based on Nvidia Tegra 3, Qualcomm Snapdragon S4 and Texas Instruments OMAP 4/5, as well as tablets, ultrabooks, laptops and touch PCs based on Intel meldfield and clove trail. All those devices are reference platform for developers and not actual products although Microsoft expect manufacturers to use those reference designs to build their products. The Touch PC used a an interesting screen which could be positioned vertically (like a normal screen). horizontally (like a surface PC) and at an angle for use cases such as an architecture reading a plan or an artist drawing a painting. They also showcased a very large touchscreen that could be used by […]
