摘要： A WWAN printed circuit antenna includes three monopole antennas in the printed circuit board. Signals are fed in from the feed monopole antenna. The first and second radiating monopole antennas are actuated by the feed monopole antenna in an electromagnetic coupling way. Therefore, a three-dimensional structure derived from the planar inverted-F antenna can be replaced, and the limitation of space usage can be overcome.

摘要： An optical projection apparatus includes an illumination system, a projection lens unit, a reflective light valve, a first beam breaker and a second beam breaker. A light beam is provided by the illumination system. The projection lens unit and the reflective light valve are disposed on the transmission path of the light beam, and the reflective light valve is disposed between the illumination system and the projection lens unit. The first beam breaker and the second beam breaker are used to cut into the transmission path of the light beam from different directions to block a part of the light beam, and part of the light beam passes through the first beam breaker and the second beam breaker. The darker image projected by the optical projection apparatus has higher contrast and better uniformity.

摘要： The invention is directed to a card edge connector. The card edge connector is electrically connected to a first circuit board for insertion of a second circuit board therein such that the second circuit board can electrically connect with the first circuit board. The second circuit board is secured within the card edge connector by means of an interference device disposed on one side of a support arm of the card edge connector. The top side of the interference device is at a height higher than the surface of the second circuit board. When the user desires to remove the second circuit board from the card edge connector, a force can be applied to the interference device to cause the two support arms to expand slightly outward, thereby permitting removal of the second circuit board and also eliminating the risk of easy breaking of free ends of the support arms associated with conventional card edge connectors.

摘要： A power conversion device includes a DC-DC converter, a DC-AC inverter and a relay. The DC-DC converter leads in a DC from an external solar panel and transforms the DC into a direct voltage. The DC-AC inverter transforms the direct voltage from the DC-DC converter into an alternating voltage and connecting to an external electric load via electric load output ends. The relay includes a coil connected to an external commercial power line via commercial power input ends, and conductive contacts actuated by the coil and serially-disposed between the commercial power input ends and the DC-AC inverter, and with the commercial power line electrifying the coils, the conduction control is formed therebetween, preventing the electric energy of the solar energy generation from inversely transmitting to the commercial power line when interrupting the commercial power service.
