Dr. Eri Takahashi is founder and CEO of EcoHarvester, green-technology startup, winner of the 2008 UC Berkeley Venture Lab Prize and 2009 NASA Innovation prize at the Rice Business Plan competition. In this episode hosted by William Lumpkins, Senior Member of IEEE, Dr. Takahashi presents her patented energy-harvesting technology that allows humans to power remote switches and controls using kinetic energy, reducing the need for batteries. Combining deep expertise in electronic design and energy-harvesting technology with an award-winning design team, BonsaiLight creates wireless light switches and controls that are battery-free and elegant in design and can operate with Bluetooth and other RF standards to eliminate the need for multiple standards in a system.

G-ONE makes ripple light which is a radio frequency controlled LED lighting system. G-ONE Inc is a Japanese company. The lighting system can be controlled through a mobile device such as an Android device. The protoypes have AAA batteries and the final version will have built in batteries with a battery life of 6 hours and potentially being rechargeable.
Mark Orvek, Linaro VP of Engineering chats with Joakim Bech, Tech Lead Security Working Group; and Deepak Saxena, Tech Lead Kernel Working Group about the work that their teams are focusing on in 2014.
Linaro and ARM engineers talk about their current activities to integrate power management into the Linux scheduler. By integrating cpuidle and cpufreq mechanisms into the scheduler, they hope to work with the community to create an energy-aware scheduler as an alternative to the current performance-oriented scheduler. This work will require improvements in other parts of the scheduler such as better description of processor topology, load estimation in the scheduler and better tools to measure the performance impact of changes to the scheduler.
Linaro is working on implementing ACPI for general purpose servers using the ARMv8 architecture. This has been controversial as it is a competing technology to FDT which has been used now for the 32bit ARM world.
ACPI has been chosen on for the general purpose servers to allow standard distributions such as RHEL and Ubuntu server to boot on hardware which they have no special support in the same way as x86 world. ACPI is used to abstract the hardware to the level the standard distribution can boot to the point it can be useful.
There is a large overlap between FDT and ACPI but they actually do things a different way. FDT is currently holding fast the the mobile and tablets market for ARM. But with Intel implementing ACPI phones and tablets nothing is certain for the future.
Linaro’s validation team demonstrates using LAVA for native toolchain builds and “hack” sessions on Arndale Octa and APM X-Gene ARMv8 platforms
Linaro’s automated validation architecture (LAVA) is typically used to execute automated tests to validate Linaro’s engineering output. However, LAVA has recently integrated features to automate builds and provide secure remote interactive sessions to developers. Linaro’s lab lead Dave Pigott shows a native toolchain build orchestrated by LAVA. This technology enables developers to validate the toolchain on many ARM processor designs as well as other architectures. Tyler Baker a technical architect at Linaro explains how LAVA abstracts the image deployment, boot process, and installation of software needed to support these “hack” sessions.
Samsung’s new CMOS image sensor technology, ISOCELL, substantially increases light sensitivity and effectively controls the collection of electrons, resulting in higher color fidelity even in poor lighting conditions. By incorporating ISOCELL, the image sensor will have 30 percent decrease in crosstalk; 30 percent increase in full well capacity; and 20 percent wider chief ray angle. Using the new technology with 1.12µm ISOCELL pixels, Samsung is introducing two new CMOS image sensors —16 and 13Mpixel.
The 16Mpixel ISOCELL imager provides a wider, clearer viewing experience to mobile device users by implementing a 16:9 aspect ratio, allowing for full-size, high-resolution images and video to be displayed on screen without field-of-view (FOV) loss. This high-speed sensor captures full FOV 16:9 full HD (1080p) video at 60fps, and for the first time in the industry, enables continuous shooting of all 16Mpixels at 30fps. Samples of the 16Mpixel ISOCELL CIS are available now and scheduled for mass production in the first quarter of 2014.
Samsung’s new 13Mpixel ISOCELL CIS features Smart Wide Dynamic Range (WDR) technology, which allows users to capture images at 30fps. With a mosaic pattern of multiple exposures, images are then processed with an advanced algorithm for wider dynamic range. This enables users to capture details clearly in both bright and dark areas even in high contrast lighting conditions. This Smart WDR feature is based on Samsung’s advanced 65nm stacked process, where the pixel array is attached right on top of the logic circuit. Samsung’s 13Mpixel product is sampling now and is scheduled for mass production in the second quarter of 2014.
Samsung shows the Exynos 5 used for advanced Android Set-top-box systems, showing multi-window, content sharing, camera integration, supporting everything in the house through this Samsung Octa Core set-top-box and Android. Gaming, advanced VOD and more. 4K video playback also supported and more.
Samsung offers its first wireless connectivity solution, S5N2120, for the growing Internet of Things (IoT) market. This solution supports IEEE 802.11 b/g/n Wi-Fi 2.4 GHz, and has an extremely small footprint, which is essential for a wide array of applications.
This solution features an integrated micro control unit (MCU) with a power amplifier, power management, audio codec and direct microphone functions. With this MCU, OEM customers can easily reconfigure their existing designs to add Wi-Fi connectivity functions. This allows for a shorter development lead-time and less engineering resources are required.
This flexibility along with excellent performance and a small footprint is optimal for battery-constrained applications such as Wi-Fi speakers, headsets, remote controls, digital & sports cameras, smart heating/cooling meters, sensors and other types of IoT or M2M applications. Samsung’s new Wi-Fi connectivity solution, S5N2120, is currently sampling and scheduled for mass production in the second quarter of 2014.
Using Widcon, the latest and future Samsung ARM Processors and memory are stacked directly through TSV (Through Silicon Via) technology, this is the next step after Package-on-Package (PoP) designs where there is a circuit board between the processor and memory, thus data had to move through wires. In the new Widcon Processor and Memory package from Samsung, this means data can move through each ball and memory bandwidth becomes wider up to and beyond 17GB/s. This structure also brings better energy efficiency. Higher bandwidth allows application processor to perform maximum performance even at low clock speed. Moreover, superior thermal dissipation comes from TSV structure also enables the new Exynos 5 Octa processor and likely future Exynos6 to maximize the full potential performance of the processor at a lower power consumption.
