Abstract: A combination heat sink and electromagnetic interference shield device is provided for a point of distribution card of a television receiver. The combination POD card heat sink and EMI shield device includes a combined thermal transfer and electromagnetic conduction portion that provides thermal and EM coupling or contact between an enclosure of the POD card and the metal control module enclosure of a television. Configured metalwork of the combination heat sink and EMI shield device provides conduction of heat from the POD card to provide the heat sink and short circuiting of developed currents to provide EMI shielding. The combined thermal transfer and EM conduction portion provides a low impedance connection between the POD card and the surrounding module metalwork of the television. This low impedance path provides a short for circulating current in the exposed metalwork that diminishes or essentially eliminates EMI.

Abstract: A projection display is provided with a light engine including a damped piezo-electric smooth picture actuating device. The light engine comprises a mirror and an actuator for positioning the mirror. The actuator includes a tilting means that couples the actuator to the mirror. The tilting means has damping material attached thereto. The damping material may be a polymeric material.
