Navigation & geolocation Standalone IMU unit has on-board Kalman filter OxTS and Colibrys jointly announced the xOEMcore IMU/INS, integrating high-grade MEMS inertial sensors from Colibrys in a small board package. The xOEMcore is the first standalone IMU on offer from OxTS, although the custom built system has been a major part of existing products like the xNAV series. The unit not only packs 6-axis gyros and accelerometers on a miniature OEM board, it also houses an on-board processor running the Kalman filter. This enables users to get the raw IMU measurements like a standard IMU, or they can pair the raw measurements with an external aiding device such as GNSS receivers so the xOEMcore takes care of the sensor data fusion. OxTS www.oxts.com Bluetooth Smart beacon integrates tri-axial accelerometer A few months after releasing the EMBC01, a multi-protocol proximity beacon, EM Microelectronic has released the EMBC02, a Bluetooth Smart beacon that integrates a 3-axis accelerometer in a sleek, weatherproof (IP-64) housing. By attaching EMBC02 to objects or people, both, proximity and motion, can be monitored by a smartphone or tablet application. The EMBC02 can be programmed to transmit proximity and identification data, like standard beacons, but it can also provide motion data (movements, vibrations, acceleration) as well as specific motion-based alarms based on accelerometer data, originating from shock, free-fall or taps. The accelerometer allows to maximize battery life by “beaconing” data only when required, e.g. while in motion, or when an alarm condition occurs. While the EMBC01 Bluetooth Smart proximity beacon can operate for more than 12 months on a single CR2032 coin cell, the EMBC02 offers even longer battery life with optimized usage scenarios where the beacon sleeps (or transmits infrequently) until the accelerometer detects movement. The device is FCC/CE/IC certified, includes a multi-function button for input and two LEDs for user feedback. EM Microelectronic www.emmicroelectronic.com Colibrys launches vibrational gyroscope Swiss MEMS manufacturer Colibrys SA has launched a gyrometer based on vibrating technology that can achieve low noise and short-term stability. The GS1000 gyrometer, based on a resonant system thay is an alternative to a fiber optic gyroscope (FOG), offers a noise figure of 0.015 degrees per second from 0.1Hz to 100Hz. In addition, Colibrys said that in june 2015 it plans to offer a vibration sensor that will surpass all existing MEMS for low frequency sensing. In general Colibrys provides high-end capacitive accelerometers and gyros resistant to harsh environments. Since its spin off from CSEM (Neuchatel, Switzerland) in 2001, Colibrys has delivered more than 8 million MEMS devices. The company moved to Yverdon-les-Bains, Switerland in 2013 as it became a wholly-owned subsidiary of Sagem, now Safran. During the relocation Colibrys acquired a 6-inch wafer fab. The company announced that it was in production at Yverdon-les-Bains in September 2014. “We are ready to speed-up our growth and to address the new market needs on the long term,” said Patrick Gougeon, CEO of Colibrys, in a statement. “These two last years, we have managed to implement strong structural changes in a record time. Thanks to a clear product development roadmap, we are confident to ensure and reinforce our position as a leader of high performances MEMS sensors.” Colibrys SA www.colibrys.com Radio modules and extended API supports swarm location services Offering significant extensions, the latest swarm API version 2.1 from Nanotron directly supports the ability to extract precise individual positions from a completely mobile swarm of radio devices in real-time. It allows users for the first time to write their own location engine based on time of flight ranging which is also known as collaborative location. For machine to machine (M2M) applications the latest API version now provides both text-based and binary host interface formats, extended control of general purpose I/O pins and an wireless extension for remote configuration and management of the swarm bee LE module allowing fully autonomous wireless configuration without the need for a local host controller. Dr. Thomas Foerste, Vice President Sales and Marketing of nanotron, points out that “customers want to further costreduce and simplify how location-awareness can be utilized and leveraged. This has been the driver for a very much enhanced API.” Swarm bee LE radio modules together with the new swarm API create a platform for tags and locationaware wireless sensors. By using both products customers obtain all the necessary functionality for a stand-alone solution. If required extra application intelligence might be added through a host controller deployed along with the swarm bee LE module. “API v2.1 enhancements facilitate customers to very rapidly use the swarm bee LE platform to develop their own customized products with any form factor and with any required functionality” said Thomas Foerste. Nanotron’s swarm products pave the way for exploring swarm intelligence to increase safety and productivity. Swarm bee LE is an autonomous swarm radio module with very low energy (LE) consumption. Nanotron utilizes its proven Chirp radio technology for this device. Chirp radios provide robust and reliable radio links required in industrial applications. The company’s patented SDS-TWR ranging method allows for concurrent communication and positioning without infrastructure. The swarm bee LE device combines accurate and precise location information with 3D acceleration sensing in a low-cost wireless module. The module supports collaborative location required for collision avoidance solutions (CAS) and high-throughput positioning needed for tracking.
