Abstract: A head unit system for controlling an object includes a head unit device that include shear thickening fluid (STF) and a chamber configured to contain the STF. The chamber further includes a set of gates between a front channel and a back channel. The set of gates includes a bypass opening set. The head unit device further includes a piston housed at least partially radially within the chamber. The set of gates is configured to control flow of the STF between the front channel and the back channel to control rotational movement of the object.

Abstract: A lamp socket adapter/converter has a main body with a medium screw-base male lamp connector on a lower end and a mount on an upper end. Standoffs extend from the mount parallel and spaced from a central axis. A printed circuit board has holes engaged with medial portions of the standoffs, and a mounting plate fixed to a female bi-pin socket is engaged with the terminal ends of the standoffs. Circuit components on the circuit board convert the electricity present at the lower end lamp connector to a different form of electricity provided to the bi-pin socket. Potting material surrounds an upper portion of the mount, the printed circuit board, the circuit components, the mounting plate and a lower portion of the bi-pin socket.
