Abstract: An antenna correcting system is provided. The antenna correction system compares amplitudes of antenna signals that are emitted or received respectively by a plurality of antenna units with each other to select one of the amplitudes as target amplitude. The antenna correction system corrects the amplitude of each of the antenna signals according to the target amplitude. As a result, the amplitudes of the antenna signals are the same as each other or approximate to each other. After the amplitudes of the antenna signals are corrected, the antenna correction system compares phases of the antenna signals with each other to select one of the phases as a target phase. The antenna correction system corrects the phase of each of the antenna signals according to the target phase. As a result, the phases of the antenna signals are the same as each other or approximate to each other.

Abstract: An electrical connector includes an insulative housing with plural passageways arranged in a hexagonal dense manner. Plural signal contacts and grounding contacts are disposed in the corresponding passageways, respectively, in a mixed manner wherein each pair of signal contacts are surrounded by eight grounding contacts. Some grounding contacts are aligned with one another along a row direction and linked together via a transverse bar, and a pair of extensions extend from the two opposite ends of the transverse bar in a column direction perpendicular to the row direction so as to have the pair of signal contacts essentially fully enclosed and shielded within a region with the boundary defined by a combination of the grounding contacts and the transverse bars.

Abstract: A bi-display mode liquid crystal display comprises a top and a bottom transparent substrate that are arranged in a parallel way, and between the two transparent substrates are a liquid crystal layer, a semi-reflector and a color filter sequentially, in addition, a top and a bottom polarizer are set on the outer surface of the top and the bottom transparent substrate respectively; by setting the semi-reflector upon the color filter, it makes the light not pass through the color filter and increase the reflection rate. Therefore, the present invention not only provides a reflective mode of high brightness gray scale display, but has a transmissive mode of beautiful color, and has the advantage of power saving and easy to use.

Abstract: A triggerable, pipelined 40-bit high speed accumulator includes trigger and continuous modes which can be operated at 50 MHz clock frequency. The high speed accumulator can be combined with static random access memory (SRAM) so as to be applied to digital frequency synthesizer, function generator and arbitrary waveform generator, etc. The high speed accumulator has two operation modes-trigger mode and continuous mode. Under trigger mode, the accumulator waits for a trigger signal to initiate its operation, while under continuous mode, the accumulator works without any trigger signal.
