The hydraulic controlling module includes a reversing valve connected to the cylinder. The PLC controlling module is connected to the reversing valve and adapted to output a control signal to locate the reversing valve in a first open position or a second open position. When the reversing valve is in the first open position, the reversing valve allows the high pressure oil to flow into the cylinder from the hydraulic controlling module, thereby to causing the piston module to push the dam to cut the gate mark; when the reversing valve is in the second open position, the high pressure oil flows back to the hydraulic controlling module.

Abstract: Disclosed herein is a system and method for downlink beamforming that takes into account imperfect channel state information (CSI) at the transmitter when determining the steering vector used in the beamforming process. The steering vector is calculated to increase the ratio of the average power of a desired signal component to the sum of the interference power of other wireless terminals, referred to as the signal-to-leakage ratio. By accounting for imperfect CSI when calculating the steering vector, the bit-error rate for a given signal-to-noise ratio is decreased. Also disclosed is a power allocation method that improves performance of the system by increasing the signal-to-interference-plus-noise ratio for all of the wireless terminals currently communicating with the base station. The power allocation similarly decreases the bit-error rate for a given signal-to-noise ratio, especially at high signal-to-noise ratios.

Abstract: This invention relates to a monolithic folded F-P cavity used for semiconductor laser, which is composed of a monolithic optical element. The monolithic optical element is made of the material having low propagation loss for a certain spectrum range. Light entering through an input/output coupling surface of the monolithic optical element is reflected several times between the input/output coupling surface and at least two high reflection surfaces within the monolithic optical element, and then at least one part of the light exits through the input/output coupling surface along the path which is collinear with the incident light but in an opposite direction. By means of integrating reflecting and coupling parts of the folded F-P cavity within a single monolithic optical material, this invention greatly improves the reliability of the F-P cavity, and has other advantages, such as insensitive to outside interferences, smaller size, simpler structure and easy usage. A semiconductor laser using the monolithic folded F-P cavity is also provided.
