  • Method of making and using an apparatus for a locomotive micro-implant using active electromagnetic propulsion
    Patent number: 11979028
    Abstract: Described is a locomotive implant for usage within a predetermined magnetic field. In one embodiment magnetohydrodynamics is used to generate thrust with a plurality of electrodes. In another embodiment, asymmetric drag forces are used to generate thrust.

  • Navigation data processing with filtering for refined position determination
    Patent number: 6144918
    Abstract: Consistent with one embodiment of the invention, a GPS signal processing system uses a behavior observer to monitor user dynamics and to aid a time-varying-gain filter arranged to perform continuous position and speed estimates. The behavior observer consists of a fast observer and a signal detector. The fast observer tacks user maneuvers. The signal detector compares outputs of the fast observer and the time-varying-gain filter to determine user dynamics and corrects operations of the time-varying-gain filter. Tracking ability is improved without degradation in steady-state position accuracy.
