NAVIGATION & GEOLOCATION LEDs tap indoor location technology for social shopping By Paul Buckley The next generation of LED lighting fixtures that communicate with shoppers’ smart devices while in-store, enabling retailers ability to understand the precise location of shoppers using an opt-in application powered by ByteLight on their smartphones and tablets. The solution combines Visible Light Communication (VLC), Bluetooth Low Energy (BLE) and inertial device sensors, and supports any Android or iOS application on a smart device equipped with a camera and/or Bluetooth Smart technology. The comprehensive approach enables retailers to reach a broad number of shoppers across the largest area - from the parking lot to anywhere in the store there is LED light. As a result, retailers can achieve continuous ROI on their conversion to GE LED lighting while providing a strategic platform for the connected retail store of the future. To help retailers increase in-store traffic and basket size, GE and ByteLight are connecting smart LEDs to digital marketing platforms to deliver contextually relevant content and create social shopping experiences. For example, welcome repeat customers with personalized shopping lists as they approach the store front, then provide an easy-to-follow map to optimize their shopping time; offer coupons and promotions based on shoppers how LEDs can go beyond the traditional ROI of energy and maintenance savings to fundamentally change the way people shop by combining data with location, said Jerry Duffy, General Manager, Global Product Management at GE Lighting. ByteLights technology ensures a cost-effective approach for indoor location by not requiring additional hardware infrastructure beyond the lights themselves. ByteLight was the first company to combine Visible Light Communication (VLC), Bluetooth Low Energy (BLE) and inertial device sensors, to determine the precise location and direction of shoppers in the aisle. Launched in 2011, ByteLights patented LED indoor location technology uses existing lighting infrastructure rather than requiring additional equipment like beacons, bringing faster ROI to LED deployments. It determines the precise location and direction of shoppers anywhere there is light with accuracy within three feet and reaches every connected shopper that has a mobile device equipped with a camera and/or Bluetooth Smart technology. Bluetooth beacon draws less than 20μA average EM Microelectronic’s COiN Bluetooth beacon is a low power solution that can be deployed anywhere iBeacon technology is used, but which also supports wireless sensor networking and many other applications over Bluetooth Smart wireless communications. COiN consumes less than 20μA average in a typical application, resulting in more than 18 months’ operation from a single CR2032 battery, which is included in the beacon. It also contains a built-in pushbutton switch, thus guaranteeing that your beacons have a full charge when they are deployed. Integrated red and green LEDs provide users with feedback about the device’s operating mode. EM Microelectronic www.emmicroelectronic.com position and direction in the aisle combined with shopping history; present customer reviews, play product information videos and connect on-demand with virtual associates to make brand choice easier. The use of GEs LED fixtures for location-based services brilliantly demonstrates Accelerometer designed for emergency call activation STMicroelectronics NV (Geneva, Switzerland) has developed a three-axis accelerometer that can measure a full-scale range of +/-24g and qualified to AEC-Q100 reliability stress tests. The unit has a digital output and can be used to trigger an automated cellular call to emergency services giving the location and severity of the collision as part of mandated emergency call procedures. The AIS3624DQ has a selectable full-scale range of 6g, 12g or 24g and 16-bit data output. It is housed in a QFN24L package that measures 4mm by 4mm by 1.8 mm and is currently available as engineering samples. Examples of emergency call systems that are becoming mandatory for new vehicles include Onstar in the United States, eCall in the European Union and ERA Glonass in Russia. STMicroelectronics NV www.st.com to provide new location-based services have been revealed by GE Lighting and ByteLight. Using GE LED infrastructure the innovative solution features GEs Lumination LED Luminaire - IS Series and ByteLights indoor location technology. ByteLights indoor location technology embedded inside GE LED fixtures provides the Magnetic position sensors with on-chip compensation AMS has introduced a family of magnetic position sensors that perform dynamic angle error compensation on the sensor chip. AMS AG (Unterpremstaetten, Austria), formerly known as Austriamicrosystems, has introduced a family of magnetic position sensors for angle detection that perform dynamic angle error compensation (DAEC) due to propagation delay on the sensor chip. The ability to output a compensated reading, provides a high accuracy down to +/-0.17 degree at 14,500 revolutions per minute and allows users to dispense with error compensation that is conventionally done in software in a separate DSP chip or in a host processor. The “47 series” are based on Hall effect principles with four sensors on the die so that the direction and speed of rotation can be married.
