Abstract: Devices, systems, and techniques are described to detect when a power transmitting and receiving system is in an inefficient position, which may cause a thermal response that less desirable than a more efficient position. The system may power transmitting device configured to wirelessly transfer electromagnetic energy to a power receiving device. Processing circuitry of the system may compute a target output power deliverable by the power transmitting device for a first duration and control the power transmitting device to output the target output power based in part on a heat limit. The processing circuitry may further calculate an energy transfer efficiency to the power receiving unit, update an adjustment factor based on the calculated energy transfer efficiency, and apply the adjustment factor to the heat limit for a subsequent duration.

Abstract: Systems and methods are disclosed for monitoring corrosion of a structure by using the structure itself as part of the electrochemical measurement. According to some implementations, linear polarization resistance (LPR) sensor devices for direct monitoring of corrosion on a structure are presented. According to certain innovations herein, a sensor device may include three electrodes, such as a counter electrode, a reference electrode, and a working electrode comprised of the structure being monitored. In further embodiments, each electrode may be configured on a polymer flexible substrate cable such as polyimide, with each electrode fabricated from a noble metal, for example, gold-plated copper, or metal systems in which the exterior surface will not oxidize from environmental exposure.

Abstract: Disclosed are systems and methods for prognostic health management (PHM) of electronic systems. Such systems and methods present challenges traditionally viewed as either insurmountable or otherwise not worth the cost of pursuit. The systems and methods are directed to the health monitoring and failure prediction of electronic systems, including the diagnostic methods employed to assess current health state and prognostic methods for the prediction of electronic system failures and remaining useful life. The disclosed methodologies include three techniques: (1) use of existing electronic systems data (circuit as a sensor); (2) use of available external measurements as condition indicators and degradation assessor; and (3) performance assessment metrics derived from available external measurements.

Abstract: A filter press cloth hanger for a filter press comprising two arms joined at their upper ends by a pivot bolt which extends through platelike members welded to the tops of the arms. Each arm is similar in construction and comprises the hollow tubular outer wall in which slides a spring loaded rod. The rod carries at its lower end outside the arm a latching plate, which has a keyhold aperture, designed to fit over the end of a suspension member for a filter plate. The rod carriers at its free end within the hollow tubular outer wall, a stop member, which is screwed to the end of the rod and prevents the rod from being completely withdrawn from the tube. The stop is also profiled to prevent rotation of the rod within the arm and bears on one end of a compression spring which biases the rod in the arm. The pivot bolt carries a roller, which can run along a support bar, extending the length of the side bar filter press on which the hanger is to be used.
