Latest Patents

One of Rawls' latest patents is the Park Lock Solenoid. This invention features a solenoid for a park lock mechanism, which includes an annular frame with a reduced diameter at one end. The design incorporates a bobbin with a coil wound around it, projecting outward and defining an integral bearing. A magnetic permeable sintered metal bushing is positioned between the integrated bearing and the annular frame. The plunger within the bobbin allows for sliding movement and has sections for connecting to a shifter. The solenoid operates in two conditions: one where the shifter is locked and another where it is unlocked through magnetic force. A manual release mechanism is also included for operation without power.

Another significant patent is the Haptic Solenoid System. This system consists of a supporting surface and a touch screen member mounted to a plastic frame. The frame has a vibration transmitting slot and at least two mounting slots. It features a pair of L-shaped poles, one stationary and the other movable, with a winding mounted on the stationary pole. The design allows vibrations from the movable pole to be transmitted to the touch screen member, enhancing user interaction.
