QuickLogic offers sensor hub for mobile devices Former FPGA vendor QuickLogic has developed a sensor hub IC that provides multi-axis context awareness at approximately 1 percent of a mobile phone’s system power budget. This allows sensors to be always-on and to be ready to sense when a phone has been picked up and to be switched on automatically, the company said. The ArcticLink 3 S1 integrates a combination of hard logic and reprogrammable fabric. The Sensor Manager block communicates with multi-axis sensors such as accelerometers, magnetometers, gyroscopes, ambient light sensors, and pressure sensors, sampling and buffering multiple seconds of the sensor data. It is a microcoded state machine and features an I2C controller. The Flexible Fusion Engine (FFE) is intended to filter and interpret sensor data before sending information up the line to the host application processor. The FFE is a microcoded finite state machine plus microcontroller ALU for processing sensor data. When coupled with the FreeMotion software from Sensor Platforms this allows the delivery of such functions as: change detector, pedometer and background magnetometer diversity. As well as the sensor hub IC QuickLogic provides a software tool for developers to define, simulate and map their algorithms to the FFE. QuickLogic Corp. www.quicklogic.com Colour light measurement sensor targets process automation EMX Industries has introduced the LEX-1000 colour light measurement sensor, designed to provide fast, high-resolution comparative measurements of the colour characteristics of a variety of light sources and illuminated objects. The introduction of colour light sensing technologies within industrial automation environments allows personnel to conduct real-time verifications of colour accuracy, quality and consistency for manufactured light sources and illuminated products, with increased throughput and improved sorting and production efficiencies. In contrast to traditional optical colour sensors that measure the light reflected from a target, the LEX-1000 proprietary optics focus the light emitted by the product onto a sensitive RGB photodiode, where it is then read and analysed for its respective red, green and blue (RGB) composition. The RGB reading is then automatically compared to pre-programmed parameters. If readings of all three colours fall within these parameters, the Reader O f fer To win: four RX62N evaluation platforms To offer you a good start in 2014, Renesas Electronics Europe is giving away four demonstrations kits worth 325 Euros each, for EETimes Europe’s readers to win. Designed as an evaluation and demonstration tool for the company’s RX62N microcontrollers, the RX62N RSK (part number R0K5562N0S000BE) provides users with a powerful debug and demonstration platform targeted at common applications. The board will also be a useful platform for evaluating the Renesas suite of development tools for coding and debugging, using the High-performance Embedded Workshop (HEW) IDE as well as programming the device using the on-board SEGGER J-Link JTAG debugger. The kit includes a CPU Board, a detachable LCD display module, a detachable AD adjustment shaft, the E1 Emulator, a connection cable (USB Cable, User Interface Cable), and a multi-region 12V power supply. The package is completed with a quick start guide and a CD-ROM including the user manual, tutorials, the HEW IDE, a C/C++ compiler package for the RX family (evaluation version) and an E1/E20 emulator debugger. Check the reader offer online at www.electronics-eetimes.com LEX-1000 sensor issues a discrete signal to indicate a colour proper match. Supplied PC-based ColorMax Windows application software provides comprehensive sensor configuration capabilities, file management and real-time analysis and evaluation, displaying the measured values as bar graphs (for absolute values) or pie-charts (for relative value). The sensor is supplied with the software, mounting hardware, interface cables, 12–30 VDC power supply, and an I/O board with status indicators. The LEX-1000 works with a variety of user-supplied light sources and provides four unique programmable colour recognition channels; three 0–5 V analogue outputs for red, green and blue (RGB); four discrete outputs; and USB or RS-232C serial data output. Tolerance is programmable from 0.5% to 50%, highspeed sampling frequency is 20 kHz, and the recommended operating distance is from 50mm to 600mm, depending upon source intensity. The sensor offers a fast response time, programmable averaging for 1 to 64 readings, a teach function for RGB values from 1%–100%, and external triggering. Operator lockout prevents unauthorized changes. Additional features include reverse polarity and overcurrent protection, an operating temperature range of -10° to +55°C, and an IP67-rated M30 316 stainless steel housing with a 12-pin IP67-rated connector and glass lens/window for enhanced survivability within demanding environments.
