MicroStrain lands $730,000 Phase II SBIR for energy harvesting RFIDs on Army helicopters

first_imgSource: MicroStrain, Inc. Williston. 9.23.2010 The US Army recently awarded MicroStrain, Inc. a Phase II SBIR contract to continue to develop a comprehensive and wirelessly networked health management capability that can be embedded directly into rotorcraft components. Providing the technology to manage the health of rotating helicopter structural components is expected to significantly reduce operational costs, increase mission readiness, and enhance safety.MicroStrain’s Phase II SBIR effort includes a demonstration of embedded energy harvesting radio frequency identification (EH-RFID) nodes with capabilities of unique identification, performance monitoring, on board storage of component usage history, and remaining useful life.Bridging the gap between design assumptions and actual usage, MicroStrain’s wireless energy harvesting sensors will continuously measure the loads on critical rotating helicopter structures during flight. By converting ambient strain and vibration energies into power, the sensors don’t require battery maintenance.The EH-RFIDs will be compatible with existing wireless sensor data aggregators (WSDAs), which feature an open architecture interface to HUMS boxes. EH-RFID nodes will also be designed to perform autonomously on aircraft which may not have an installed HUMS system. Steve Arms adds, ‘One of the unique aspects of our Army Phase II SBIR effort is that the EH-RFID sensor nodes will be designed to consume very little energy. This facilitates continuous operation using highly miniaturized energy harvesters, which greatly reduces the barriers to embedded sensor installation.’The development of usage tracking RFID nodes with energy harvesting capabilities will represent a major advance by enabling significant cost savings and opening up many new applications in structural health monitoring and machine condition based maintenance.MicroStrain, Inc is a privately held corporation based in Williston Vermont. MicroStrain produces smart, wireless, micro-miniature displacement, orientation and strain sensors. Applications include advanced automotive controls, health monitoring, inspection of machines and civil structures, smart medical devices and navigation/control systems for unmanned vehicles, and energy harvesting technologies.last_img read more

Mason City woman pleads guilty to federal charges of stealing drugs from patients

first_imgMASON CITY — A Mason City woman accused of federal charges of stealing drugs and illegally accessing patient information has pleaded guilty.32-year-old Samantha Rogers pleaded guilty on Monday in US District Court in Cedar Rapids to the charges of acquiring a controlled substance by fraud, wrongfully obtaining health information for personal gain, and making false statements related to health care manners. Federal authorities say the charges stemmed from activity between October of 2017 and May of last year.According to the criminal complaint, Rogers was fired in January 2017 from the IOOF home after allegedly being caught on video taking prescription pills from the purse of another employee. She continued to be employed at Mercy-North Iowa when a nursing aide reported pain pills missing from her purse in May 2017.Rogers then was accused of accessing patient records after being hired to work at Northern Iowa Therapy in Waverly in September 2017 in attempts to obtain or steal prescription medication. She’s suspected of taking a patient’s unused Percocet and of breaking into another patient’s home in Forest City in a search for drugs.No sentencing date has been scheduled.last_img read more
