Abstract: The apparatus provides a proper step width for patients during gait training with neurological disorders, such as spasticity or paraparesis of the lower extremities. The apparatus provides proprioceptive feedback through the ankles during gait training with an assistive device (cane, walker, or parallel bars). The apparatus can be adjusted to different step widths depending on the patient and the physical therapist's recommendation. The result would be an improvement in the patient's gait pattern over time (with less risk of injury to the patient) and an improvement in the method used by the physical therapist for gait training for this problem.

Abstract: A directional ordnance for a missile. The missile contains circuitry to determine the direction of a target relative to the missile and to selectively detonate directing charges to force the blast from the warhead towards the target. The circuitry for determining the direction of the target includes two transmit antennas, each transmitting a different pseudo noise sequence, and two receive antennas; each coupled to a receiver which can determine the level of each pseudo noise sequence at each receive antenna. The relative strengths of the different pseudo noise sequences tell the direction of the target relative to the transmit and receive antennas.

Abstract: A monopulse receiving arrangement is shown to comprise orthogonally polarized and electrically separate monopulse antenna arrays, one such array being made up of juxtaposed slotted waveguides and the other being made up of at least one monopulse array of dipoles printed on a dielectric material.
