摘要： The present invention describes a technique for achieving high peak power output in a laser employing single-stage, multi-pass amplification. High gain is achieved by employing a very small “seed” beam diameter in gain medium, and maintaining the small beam diameter for multiple high-gain pre-amplification passes through a pumped gain medium, then leading the beam out of the amplifier cavity, changing the beam diameter and sending it back to the amplifier cavity for additional, high-power amplification passes through the gain medium. In these power amplification passes, the beam diameter in gain medium is increased and carefully matched to the pump laser's beam diameter for high efficiency extraction of energy from the pumped gain medium. A method of “grooming” the beam by means of a far-field spatial filter in the process of changing the beam size within the single-stage amplifier is also described.

摘要： The present invention discloses a burr removing apparatus including a base for placing the compact disc on, and a pressing apparatus equipped on the base and corresponding to the inner circle of the compact disc for moving up and down to eliminate a bur at the inner circle of the compact disc. An upper and a lower inhaling apparatus are respectively equipped in the pressing apparatus and the base, and extend respectively to the surfaces of the pressing apparatus and the base. The upper and lower inhaling apparatus have the upper and lower inhaling holes to inhale the bur eliminated. The present invention eliminates and inhales the redundancy before bonding the discs, so the smoothness of the disc can be improved to avoid the bubbles while bonding, and providing a disc with good mechanical properties and weather-resistance.

摘要： A display FIFO memory management system and method includes a programmable FIFO emulator for emulating a drain and fill time of the display FIFO memory to automatically predict a number of register entries remaining in the display FIFO memory at each predefined clock cycle. A programmable timer/counter has programmable precision to accommodate varying bandwidths of display screen display modes and is used to determine the number of entries remaining so that the emulator can accommodate varying screen display modes. A FIFO controller controls the timing of fetching display data from memory to fill the display FIFO memory based on the prediction of the number of remaining register entries in the display FIFO by the programmable emulator.

摘要： A method and apparatus for sequencing memory accesses in a video graphics system such that page faults are effectively hidden is accomplished by receiving a memory access request from one of a plurality of clients, where the plurality of clients includes both linear clients and tiled memory clients. The clients access data stored in a memory that includes at least two banks. Once the memory request has been received, it is evaluated based on other pending requests in order to determine the optimal ordering pattern for execution of the memory requests. The optimal ordering pattern typically includes sequencing alternating accesses between the two banks of the memory such that when a page fault is occurring in one bank of the memory, a memory access is occurring in the opposing bank. Once the ordering of the memory requests has been performed, the requests are executed.

摘要： An engine ignition control method and system for controlling ignition timing that computes a predicted crankshaft angular velocity based on prior computed and verified crankshaft angular velocity and acceleration and determines a capture window of the next crankshaft position sensor pickup signal for the verification of the predicted crankshaft angular velocity. The ignition control system also utilizes both crankshaft position pickup signals and the intake manifold air pressure measurements for determining the stroke of the combustion cycle in turn providing more accurately timed signals for the fuel injection and ignition systems. During engine starts, the engine ignition control system performs a series of continuous spark-triggering, determines if each spark-triggering being at the correct or incorrect point in the combustion cycle by detecting if there is any engine acceleration and adjusts the generation of the signal for the next spark-triggering accordingly.
