Abstract: A protective heat sink for an electronic component dissipates heat generated thereby. A first heat conductive member is mounted to the top side of the electronic component. A protective cap having an aperture formed therein is mounted on the printed circuit board such that it extends over the electronic component and the first heat conductive member. A second heat conductive member is mounted to the first heat conductive member and extends through the aperture in the cap such that heat generated by the electronic component is transmitted to the first heat conductive member and then dissipated to the environment by the second heat conductive member.

Abstract: An improved strain relief device is connectable to a cable end portion to resiliently resist both bending and torsional loads imposed thereon. The strain relief device is formed from a resilient material and includes a tubular body portion which receives and is fixedly secured to the cable end portion to be protected. Projecting radially outwardly from the outer side surface of the tubular body are a circumferentially spaced series of elongated, resilient rib members which extend lengthwise in a direction parallel to the axis of the strain relief body. The ribs taper radially outwardly along their lengths and collectively function to progressively resist both bending and torsional loads imposed upon the cable end portion in a manner maintaining a generally linear relationship between the bending and torsional loads on the cable end portion and the resulting axial lengths of the strain relief body portion being bent or twisted.

Abstract: An improved air distribution system for cooling electronic components mounted on printed circuit boards. The system includes an air plenum chamber of rectangular cross section. Openings are formed in the side walls of the chamber to permit air under pressure from within the chamber to flow outwardly in a direction substantially normal to the outer surfaces of the side walls and over the components to be cooled. A baffle in the form of a thin sheet of metal is mounted in the plenum substantially parallel to the side walls to divide the interior into two substantially equal portions. A large number of small round holes are formed through the baffle the area of the holes occupying substantially 36 percent of the total area of the baffle. An air pump supplies air under pressure to the interior of the plenum chamber.

Abstract: Golf club head apparatus is disclosed which includes a curved top portion with a concave portion beneath the curved top portion and internally adjustable weights are disposed adjacent the face of the club head.
