摘要： A key structure includes a substrate, a key cover positioned on the substrate, a first fixed contact, a second fixed contact and a conductive portion. The key cover includes a first movable contact, a second movable contact and a fixed portion. The first movable contact, the second movable contact and the fixed portion are located at inner surface of the key cover. The first fixed contact, the second fixed contact and the conductive portion are electrically positioned on the substrate and correspond to the first movable contact, the second movable contact and the fixed portion. When the key cover deforms, the first movable contact and the second movable contact move toward the substrate, the second movable contact and the first movable contact electrically contact the second fixed contact and the second fixed contact to generate a first command signal and a second command signal.

摘要： Design techniques and their circuit designs for versatile and scalable video coding are proposed, in which the inner product operation in the transform coding expression is taken apart into a series of add and shift operations, and the expression is partitioned into several sub-expressions. Taking each order of the add-and-shift series as a clock period, several adders/subtractors and a shift accumulator are used to carry out corresponding additions/subtractions and shift operations to finish the inner product operations. The calculating result is accumulated until all the orders are finished. The final accumulated value is the output of the transform coding. Data throughput rate can thus be enhanced to save the power consumption of the circuit system. Moreover, a dynamic guarded computation method and a switching power suppression technique are provided to further lower the power consumption.

摘要： An optical projection apparatus is provided, where a reflective light valve, a light deflecting device and a lens set are arranged on an optical path of the light beam providing by an illuminating system. The light deflecting device is located between the illuminating system and the reflective light valve, and the lens set is located between the reflective light valve and the light deflecting device. When the light beam is incident to the reflective light valve through the light deflecting device and the lens set, the light beam is converted into sub-image beams, and then the sub-image beams are reflected to the lens set. The projection lens set arranged on an optical path of the sub-image beams has a pupil located on the light deflecting device. The lens set converges the sub-image beams on the pupil and then the sub-image beams are incident to the projection lens set for imaging.
