Abstract: A method for ensuring verifiable parking of micro-mobility vehicles in designated locations through centralized or decentralized systems. The invention seeks to solve situations of scattered and disorderly parking of micro-mobility vehicles. Through sensing devices, the main system receives information of a parked vehicle within a designated space, which may include vehicle features or alphanumeric code, and processes the data for verification via machine learning or other techniques. Upon verification of the proper parking of a vehicle, a ledger logs the corresponding user with the parking event. Cryptocurrency tokens may be distributed to users or operators upon verification of proper parking, depending on whether the vehicle is owned by the user or part of a shared fleet.

Abstract: An improved microsystems testing and characterization system which allows the system user to identify specific structures, and thereby to initiate an automated testing sequence to be applied to that structure or a series of structures. The integrated control system that governs the present invention automates the power supply to the device under test, the precision motion control of all components, the sensor operation, data processing and data presentation. Therefore operation is autonomous once the microstructure is in place and the testing sequence is specified. The integrated testing system can be used to perform tests on an entire wafer or on a single die.

Abstract: A microelectromechanical power relay uses mercury, or a similar liquid metal with high surface tension, as a flexible non-degrading contact mechanism. The basic systematic requirements for the micro-relay include large current carrying capacity, high speed, use of control voltages readily available in the given application, and an acceptable hold-off voltage. The preferred embodiment of the present invention includes the novel configuration of a liquid metal current carrying switching device.

Abstract: This invention relates to an apparatus for making highly sensitive differential measurements of acceleration. The vibration sensor includes the use of moveable gate field effect transistors to sense the motion of a cantilever beam relative to the motion sensed by a reference structure, it also includes an actuator element formed by a pair of electrodes actuating electrostatically on the beam. A feedback control loop is also included for force balance operation resulting in a very wide dynamic range for the sensor.
