Latest Patents

One of his most recognized patents is the "Reactionless, Momentum Compensated Payload Positioner." This invention is designed to be mounted on a supporting body, providing momentum compensation for oscillatory and scanning payloads. It effectively suppresses reactions in the supporting body that occur when the aiming angle of the payload is altered. The payload positioner features a gimbal assembly with at least two axes of rotation, including elevation and azimuth.

The invention incorporates a pair of reactionless drive modules that allow for the rotation of the payload around both axes. Each module consists of a housing, a main drive shaft connected to the payload, a DC electric motor for rotating the drive shaft, and a flywheel. The flywheel counter-rotates with respect to the main drive shaft, effectively eliminating reaction torques in the supporting body as the payload's aiming angle changes. This innovative design also provides momentum compensation to the payload, significantly reducing gyroscopic effects during rotational movements.
