Reader O f f er Exploring through-wall presence detection This month, Novelda is giving away two full XeThru Inspiration kits worth 1499 US Dollars each, for EETimes Europe’s readers to experiment first hand with its XeThru technology. Based on the use of radio waves, rather than infrared, ultrasound or light, the company’s X2M1000 Inspiration modules can detect presence just from the chest movement while breathing, and measure both the rate and depth of breathing, allowing breathing patterns to be tracked in real-time for a plethora of presence and health-care monitoring applications. The technology ‘sees through’ a variety of objects including lightweight building materials, duvets and blankets to provide non-contact sensing at a range of up to several metres, within a 60° field of view. The XTIK Inspiration Kit offers a quick start for proof of concepts and prototyping. It includes two X2M1000 Inspiration modules (50x70mm), two USB communication boards, the XeThru Explorer software for module configuration, data logging and visualisation, and a programmer unit in case the firmware needs to be updated. Each package comes in a practical briefcase with room for additional hardware.

The unit provides a single, quick, test to show the health of the battery at variable loading conditionings for Impedance, Voltage, Temperature and Current measurements (simultaneously or independently) with user-friendly software. The 107x220x55mm unit finds application in the field management of almost any battery, including UPS back up batteries in telecom industrial systems, renewable energy power plants (solar, water, wind), marine, aerospace, military, automotive and the like. Providing abundant data logging and accurate trend analysis the unit has an internal SD Card back-up to store up to 100,000 (100K) data. Data is available in both text and graphic mode. The WENS 900 battery quality analyser is designed for measuring the internal resistance, open-circuit voltage and terminal temperature of secondary batteries, including Lead Storage Cells (Lead -Acid batteries), nickel-cadmium batteries, lithium-ion batteries and nickel-metal hydride batteries. It has an AC four-terminal method to measure the internal resistance by eliminating lead resistance and contact resistance to get the accurate results which are simultaneously displayed along with voltage and temperature. There are 99 sets of composite comparator functions, which can be set at resistance and voltage values to get reliable detection of battery deterioration. Integral with the unit are pin type leads, supplied as standard, for easy contact with the battery electrodes to get a more accurate connection. 4-terminal measurement is possible and there is a clip type lead with temperature sensor and a clamp adaptor for DC current measurements. Aspen Electronics www.aspen-electronics.com SDK targets InfoADAS development Carmakers increasingly complement traditional in-vehicle infotainment (IVI) features and functions through Informational Driver Assistant Systems (InfoADAS). The latter add functions such as surround view, pedestrian and lane detection with the overarching goal to make dri-ving safer. Since these functions are typically camera-based, they generate huge amounts of data that of course have to processed. To support these development, Texas Instruments has introduced a Software Developers Kit (SDK) custom-made for InfoADAS. TI’s InfoADAS SDK enables developers to xtend investments in infotainment with the addition of innovative InfoADAS use-cases to enhance the driver’s awareness of the conditions inside and outside the vehicle, without compromising the performance of either IVI or InfoADAS systems. In addition it helps developers to reshape traditional infotainment architectures by integrating additional functions on TI’s DRA7xx “Jacinto 6” infotainment processors. Functions and options of Informational ADAS With the increasing deployment of cameras and sensors in vehicles to make the driving experience safer, there is a need to collect, analyze and display further information to the driver without significantly increasing overall R&D investments or bill-of-materials (BOM). The InfoADAS SDK provides scalability across high-level operating systems (HLOS) and “Jacinto 6” devices for reuse of existing designs and resources. It can also be used as a pluggable InfoADAS subsystem to existing head unit applications. To act as a reference for customer’s productized algorithm development, the InfoADAS SDK includes sample vision algorithms to demonstrate the framework capabilities, and also includes hooks to extend the framework for higher-level application features such as park guide overlays. In addition to the existing HLOS SDK supported on the “Jacinto 6” platform and Vision SDK dedicated to control safety functions supported on the TI TDAx processors, the delivery of the InfoADAS SDK unifies the software architecture across TI’s automotive processors, “Jacinto” and TDAx, for easy integration and scalability. The DRA7xx family of processors provides a hardware- and software-compatible platform capable to augment existing infotainment products with informational ADAS features. To enable InfoADAS, there is no hardware change required besides upgrading the system to route cameras to the processor. This allows customers to leverage cameras both inside and outside the vehicle together with existing infotainment platforms.
