Abstract: An apparatus for insertion into an inflatable sports ball, the apparatus comprising a plate comprising a valve wherein the valve comprises an aperture for selective communication of air, a circuit board comprising a transmitter and a battery electrically connected to the circuit board.

Abstract: An apparatus for permitting electrical connection between the exterior of an inflatable sports ball and electronics located inside the inflatable sports ball is provided. The apparatus comprises a support member, the support member having separate first and second through-holes provided therein for respectively connecting the exterior of the inflatable sports ball with the interior of the inflatable sports ball. An electrical connection port is located in the first through-hole of the support member for permitting an electrical connection to be made through the first through-hole. An air valve is located in the second through-hole of the support member, the air valve comprising an aperture for selective communication of air.

Abstract: A power resistor for use in an automotive battery diagnosis circuit. The resistor includes a length of conductive material stamped to form a ribbon, which has formed along its length pins arranged perpendicular to the length of the ribbon and in a plane perpendicular to the stamping direction. The pins are arranged to provide in use means for electrical connection and mechanical fixation to the circuit.
