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.

Abstract: A meter value that reflects the amount of genetic material stored in a reserve is stored in a database for each reserve in a bank. Meter values allow a user to track the amount of genetic material in the reserves of a bank without needing to physically measure or disturb the reserves unnecessarily. As users withdraw and deposit genetic material from and into a reserve, the meter value is changed to reflect the change in the amount of genetic material in the reserve. In certain embodiments, the use of meter values enables accurate and instant accounting of a large number of reserves of genetic material for a large number of individuals. Users and/or individuals may be notified when a meter value falls below a threshold. Notifications may prompt a user to generate additional genetic material from biological sample or an individual to provide additional biological sample.
