Abstract: A closed-loop temperature controller employing at least two sensors: a control temperature sensor and a safety sensor at the heat-transfer element. The heat-generating element is separated from the controlled mass/volume by a transport delay so that the mass or volume that is being heated or cooled is located in a vessel which is located remotely from the heat-transfer unit. Thermally conducting fluid flows through a conduit that connects the heat-transfer unit to the vessel. Upon fluid flow interruption or control sensor removal, the temperature controller quickly detects thermal runaway before the safety sensor has reached the critical temperature. In heated systems, the temperature controller will therefore minimize direct damage and/or overshoot damage caused by excessive heat. It will also maintain the heater's output at an elevated, but non-damaging level to enable a fast recovery to the original setpoint temperature after the nonlinearity subsides.

Abstract: The present invention measures jump heights using an IMU sensor module slipped in a pocket of a removable side ankle mount clip placed over any low, mid or high tops ankle athletic running shoe. A micro-processor in the IMU sensor module converts analog jump height data collected with real time digital signal processing to digital data sent to specialized algorithms loaded in a RF paired smartphone to refine the digital data to accurately calculate the height of the jump. The clip has two downward spaced legs joined by a curved arch at the top with a first leg being flexible and fitting snugly against a wearer's ankle below the fibula bone with the curved arch resting over the shoe's collar. The second leg has a foot extending outwardly from the curved arch to form a pocket with a top opening to receive and snugly hold the module.

Abstract: An athlete wearing footwear measures jump heights with a motion sensor mounted on the footwear over toes of the athlete. By sensing vertical jump start motions the sensor detects jump start and finish times of ?4 g start and ?4 g landing. The sensor, a body wearable mems sensor developed by JAWKU, L.L.C., has a previously installed generic factory scale calibration factor. The athlete replaces this calibration factor with a new calibration scale factor selecting an “absolute” external reference device which measures jump height. This device measures several jump heights then inputted to an algorithm app in the sensor to calculate the new calibration scale factor customized to the actual athlete. The motion sensor has built in programming apps to periodically receive an upgraded factory scale calibration factor which upgrade is based on an ever increasing data pool of jump heights.
