摘要:
The invention provides a method and device for cooperative relay with multiple relay stations in the wireless telecommunication network. To be specific, according to the invention, in single-hop or multi-hop relay telecommunication link, the relay device and other relay devices within the same hop select space diversity or space multiplexing to carry out cooperative relay operation according to the processing indicating information from the base station, thus obtaining space diversity gain and space multiplexing gain.

A fast method of transforming competent cells is described. The competent cells are thawed at room temperature or in a water bath. Plasmid DNAs and competent cells are mixed together, then the mixture is subject to heat shock treatment. After plating the mixture on a low-temperature selective medium by a low-temperature plating tool, the competent cells are cultured on the selective medium.

A processing system includes an arithmetic logic unit (ALU) sub-system that allows data associated with a prior instruction to be preserved for use with a next instruction or subsequent instruction without having to reload the value using an intermediate register. The ALU sub-system includes a pair of ALUs communicatively cross-coupled with a pair of accumulators. The processing system also includes a data selector coupled to the ALU sub-system for use with memory contention prediction. The data selector includes a constant generator that controls storage of data associated with a previous instruction in a bypass element, and a selector to choose between data from a databus element and data stored in the bypass element.

Disclosed is a wireless communication system comprising a plurality of antennas, a plurality of base stations, each base station being adapted to connect to one or more of the antennas over an available spectrum, and a wireless switching module. The wireless switching module is adapted to allocate one or more portions of the available spectrum to each antenna dependent on a compatibility constraint on the antennas, and assign each antenna for connection to a base station.

The present invention provides a handover control method in a wireless access system, a relay station and a base station for performing handover control in a mobile multi-hop relay wireless access system such that the wireless access system is enabled to cover a wider area. To achieve the above object, the present invention provides a handover control method in a wireless access system, wherein the wireless access system comprises a mobile station and a base station, which receive and send message via a wireless channel, and further comprises a relay station for forwarding message from the mobile station and the base station under control of the base station, characterized in that the method comprising a relay station measure and arbitration step in which the relay station measures the message and arbitrates whether to relay the message, and a base station measure and handover step in which the base station measures the message and arbitrates whether to perform handover.

A method for manufacturing trench MOSFET device with low gate charge includes the steps of providing a substrate of first conductivity type; forming an epitaxial layer of first conductivity type on the substrate; forming a body region of second conductivity type in the epitaxial layer, the body region extends downwards from the surface of the epitaxial layer; forming a plurality of trenches in the epitaxial layer, the body region having the trenches formed therethrough; forming a first insulating layer on the body region and on an inner surface of each trench; forming a ploy-silicon spacer on the first insulating layer on an inner side-wall of each trench; filling a dielectric structure in the lower portion of each trench; and filling a ploy-silicon structure on top of the dielectric structure in each trench. Through the trench MOSFET device, the gate capacitance and resistance thereof are reduced so the performance is increased.

FIG. 1 is a perspective view of the wheel rim, showing my new design; FIG. 2 is a front view thereof; and, FIG. 3 is a side view thereof. The broken lines in the drawings are for illustrating portions of the wheel rim and form no part of the claimed design.
摘要:
A disposable pre-filled syringe has a protecting tube, a medication filling tube, a separating plug, a pushing module, and a needle module. The medication filling tube is made of chemically inert material and is mounted in the protecting tube. The separating plug is mounted in an end of the medication filling tube. The pushing module is slidably inserted into the medication filling tube opposite to the separating plug. The needle module is mounted on an end of the protecting tube.
