Wireless power receiver IC charges mobile devices quickly Toshiba Electronics Europe has launched a wireless power receiver IC that will enable mobile devices to be charged wirelessly as fast as if they were connected to the charger via a cable. The TC7764WBG supports a maximum power output of 5 W and is compliant with the Qi standard’s low power specification V.1.1.2, defined by the Wireless Power Consortium (WPC). Wireless power transfer allows adoption of a fully insulated case free of exposed charging ports, an advantage that is stimulating demand for waterproof and dustproof portable products, such as smartphones and tablets. However, wireless charging has not always been as fast as charging by cable. To overcome this difference, Toshiba has optimised the circuit design of the TC7764WBG so that maximum output power is increased to 5 W and a maximum power conversion efficiency of 95% is achieved (excluding the influence of the power signal receiving coil and tank capacitor). This enables mobile devices to be charged wirelessly as fast as if they were connected to a cable charger. The IC integrates a Qi protocol authentication circuit for power transfers, foreign object detection functions, under-voltage lockout and over-voltage lockout functions for the external power supply bypass option as well as thermal shutdown functions. The IC comes in a 2.4x3.67x0.5mm WCSP28 package. Toshiba Electronics Europe www.toshiba.semicon-storage.com Control systems optimized for the Industrial Internet of Things NI has announced embedded systems hardware based on the open, flexible LabVIEW reconfigurable I/O (RIO) architecture. This hardware includes the high-performance CompactRIO Controller for integrators with rugged, industrial applications, Controller for FlexRIO for designers with high-performance embedded applications and Single-Board RIO Controller for designers who require more flexibility in their embedded applications. These controllers integrate the latest embedded technologies from Intel and Xilinx to deliver unparalleled performance and flexibility, empowering system designers and machine builders to address the most demanding control and monitoring challenges. The controllers are fully supported by LabVIEW software, the LabVIEW FPGA Module and NI Linux Real-Time, now based on Security-Enhanced Linux, which enables advanced security features for Industrial IoT applications. NI www.ni.com Wireless occupancy sensors deliver Smart LED lighting flexibility Dialight has unveiled a wireless occupancy sensor which is a battery-powered plug-and-play sensor that speeds and simplifies installation to provide maximum lighting control flexibility and energy savings in industrial applications. Designed to integrate seamlessly with any Dialight smart lighting system, the wireless sensor can be placed virtually anywhere within a facility, without the need to install or move cabling, for nearly unlimited lighting control options. A single sensor can be programmed to control multiple lights and groups of lights, eliminating the need to install a sensor on every light. Using Pyroelectric InfraRed (PIR) technology, each sensor can instantly switch a single light or a group of lights from off to on or from a dimmed state to on when motion is detected for full visibility and brightness only when needed, greatly reducing on-time and power consumption. Multiple sensors can be linked to a single Dialight gateway to manage several (or up to 100) nodes (sensors and lights) from a single wall controller. Programmable dimming and customizable timeout options allow facilities to configure fixture on-time for each sensor at oneminute intervals. Lights can be programmed to remain on for up to 30 minutes once motion is no longer detected and then dim or turn off instantly. Each light and sensor in the network can be securely monitored and configured remotely from anywhere through the Dialight cloud-based gateway portal using a tablet, laptop or smartphone. Featuring 10-year lithium batteries and a self-healing 2.4 GHz IEEE 802.15.4 mesh networking system, the occupancy sensors are available in two lens types. A wide-angle lens detects motion up to 30 feet at a 120-degree angle, while a long-range lens detects motion up to 100 feet away at a narrow 10-degree angle, best suited for wall mounting and aisle coverage. Dialight www.dialight.com New GPU cores for Qualcomm’s Snapdragon processors Qualcomm Technologies has unveiled its next-generation visual processing technology with new versions of its graphics processing unit (GPU) and image signal processing (ISP) unit, which the company believes will deliver significant advancements in performance, power efficiency and user experience to its Snapdragon processors. The Qualcomm Adreno 5xx GPU architecture is claimed to deliver increased speed and efficiency over the previous generation and supports highdefinition mobile graphics while introducing general-purpose compute co-processing for exceptionally low power consumption. The first two GPUs available on the new architecture, the Adreno 530 and Adreno 510, will be available integrated within the forthcoming Snapdragon 820 and Snapdragon 620/618 processors. In addition, Snapdragon 820 will also debut the new 14-bit Qualcomm Spectra image signal processing (ISP) unit, designed to support superior DSLR-quality photography and enhanced computer vision. The Qualcomm Spectra ISP is expected to deliver superior image quality, with more natural skin tones via advanced, 14-bit dual ISPs supporting up to 3 simultaneous cameras and up to 25 megapixels at 30 frames per-second with zero shutter lag. It features a flexible hybrid autofocus framework and multi-sensor fusion algorithms for next generation computational photography.
