Abstract: A ground-based computing system receives data of performance parameters for like components disposed on like aircraft, and determines corresponding levels of degradation and rates of change of degradation for the respective like components. A fleet-level of degradation for groups of like components is generated based on analysis of the combined degradations of the like components in the respective group and models of components revised. A predicted time for maintenance for each like component is determined based on the corresponding at least one of the RUL and SOH of the like component, thereby enabling cost effective maintenance determinations for components based on a fleet-level information. The ground-based computing system transmits a modified component model to the like aircraft to replace a prior version of the component model which is used to generate on-board degradation analysis, thereby enhancing the accuracy of on-board degradation analysis based on fleet level data.

Abstract: The weight sensor vehicle security device comprises a vehicle and a security circuit. The security circuit measures the weight of the operator. The operator enters a security code into the security circuit. The operator then enters a security code. The security circuit compares the measured weight of the operator to a weight of the operator that is associated and stored with the security code. If the measured and stored weights match, the security system enables the operation of the vehicle. After the vehicle travels a previously determined distance, the security circuit repeats the procedure. If the measured and stored weights do not match, the security system disables the operation of the vehicle.
