Latest Patents
One of Witman's latest inventions is a drone load release system. This system features a drop kit that attaches to a pair of parallel Picatinny rails on a drone. It utilizes drop mechanisms that hold one side of a load-bearing basket, while the opposing side is pivotally secured to a goggle plate. The drop mechanisms employ a drop cam that rotates between open and closed positions. When the drone reaches a designated location, a signal activates motors associated with the drop mechanisms, allowing the basket to release its load.
Another significant invention is the ground drone-based sports training aid. This electrically driven drone travels along a programmed path that corresponds to a pass catcher's travel during a play. It matches the speed and run cuts of the pass catcher, with the play communicated wirelessly from a handheld device. A target on the drone allows a quarterback to throw a football at it, refining their timing and accuracy. Sensors track the football's and quarterback's trajectories, collecting data for analysis by the coaching staff.
