Abstract: The positionable towing hitch includes a first beam supporting a movable housing assembly and a second beam assembly movable in the housing. The first beam protrudes out of the housing for mounting to a hitch receiver of a vehicle. A first beam driver assembly is coupled to the first beam to selectively extend and retract the housing with respect to the first beam in a horizontal direction. A second beam driver assembly is coupled to a second beam to selectively raise and lower the second beam with respect to the housing in a vertical direction. A ball mount bracket is fixed to the second beam for mounting a ball mount thereon to move with the second beam. The movements of the housing and the second beam facilitate positioning of the ball mount for connection to a trailer to be hitched.

Abstract: The tactile directional guide system provides directional information in the form of vibrations for use during emergency evacuations and the like. The tactile directional guide system includes a vibrational module adapted for mounting on a support surface, such as the floor or wall of a hallway or corridor, as non-limiting examples. The vibrational module includes a plurality of members linearly arrayed along a longitudinal direction and a plurality of vibrators respectively coupled to the plurality of members. A controller is in communication with the plurality of vibrators and is configured to selectively sequentially actuate the plurality of vibrators in either a forward longitudinal direction or a rearward longitudinal direction to provide a tactile directional output.
