Abstract: Systems, apparatuses, devices, and methods for monitoring mobility aids are provided. An example apparatus includes a wheel attachment assembly, a motion sensor, and a transceiver. The wheel attachment assembly is configured to removably attach to a wheel of a mobility aid. The motion sensor is configured to measure rotation of the wheel attachment assembly. The transceiver is in electronic communication with the motion sensor and configured to transmit data based on measurements from the motion sensor. An example system includes a monitoring device and a stationary communication node. The monitoring device is configured to removably attach to a mobility aid and includes a transceiver and a motion sensor configured to measure motion of the monitoring device. The stationary communication node is configured to communicate with the monitoring device. An example method generates alerts based on data from an attachable monitoring device.

Abstract: A software testing system for testing software module responsiveness to string input tokens having lengths which span a range of integral values. The system can include a range bounding processor configured to probe the software module across a communicative coupling with string input tokens having selected ones of the lengths without probing the software module with string input tokens of all of the lengths which span the range of integral values.

Abstract: Microwave signals are coupled from a microwave module to a microstrip transmission line, each installed on a chassis plate. The microwave signals are fed through the bottom or side of the microwave module using a feedthrough pin mounted in the module. The feedthrough pin extends from the microwave module interior into a channel defined in the chassis plate and to a microstrip line on the opposite side of the plate. An electrically conductive gasket is placed about the feedthrough pin between the microwave module and chassis plate to reduce signal leakage and enhance ground continuity. An insulating sleeve is installed about the feedthrough pin in the chassis plate channel and provides a nominal clearance (e.g., 0.005 inches) within that channel to allow for manufacturing and assembly tolerances and to enable feedthrough impedance to be substantially insensitive to the position of the feedthrough pin and insulating sleeve within the channel.
