Abstract: A stimulation system for a patient is provided. The system comprises: at least one implantable device comprising at least one implantable antenna; and an external device comprising at least one external antenna, wherein the at least one external antenna transfers power to the at least one implantable antenna. The at least one implantable device delivers therapy to the patient. A patient attachment device or body covering positions the at least one external antenna relative to the patient.

Abstract: A device to induce rotation of aircraft landing wheels is disclosed, using only the force of oncoming air to bring them up to synchronous ground (landing) speed during approach to landing. A complete, independently operating system with its own sensors, microcontroller, motors and control linkages, which does not interface with any of the aircraft's instumentation or systems, continually measures the actual ground speed of the aircraft during final approach, transmitting this flow of data to a microcontroller for continuous translation into required RPM for each tire diameter and monitors the precise RPM of each landing wheel through non-contact photo-tachometers whose outputs are multiplexed into the microcontroller. The system provides continuous control over the RPM of each landing wheel through air intake ducts with servo motor driven inlet vanes gating incoming air to the wheel-mounted impellers.
