06/12/12 — ChronicleHerald—An abandoned coal mine near Springhill, Nova Scotia was the test site this winter for an underground robot communications system developed by Ultra Electronics Maritime Systems Inc. of Dartmouth, Nova Scotia. “We wanted to validate the capabilities of the system under the most realistic conditions possible,” Steve Parsons, business development manager at Ultra, said Monday in an interview. It was a first-time demonstration of wireless through-the-earth command and control of a remotely operated robotic vehicle, Parsons said. “It’s the first time the capabilities of this technology have been successfully placed on a robot,” he said. “There are a few other…

06/05/12 — MicroStrain—LXRS Lossless Data for Wireless Sensor NetworksMicroStrain's new "lossless" wireless communication protocol (patent pending) supports scalable networks of high speed sensor nodes without data loss due to temporary radio frequency (RF) fading, multipath, or interference. MicroStrain’s users have previously enjoyed a typical RF packet success rate of 99 percent - not bad.  But now, with MicroStrain’s new LXRS “lossless” protocol, wireless sensor networks can deliver 100 percent reliable data throughput under most operating conditions. • Lossless wireless communication protocol providing 100 percent packet success rate • Extended Range radio link to 2 kilometers • Scalable wireless sensor networks supporting continuous,…
