20090274041 | Fast feedback contention-based ranging procedure in wireless communications systems - A fast feedback mechanism is provided in a contention-based ranging procedure. A Subscriber Station (SS) initializes a ranging procedure by sending a ranging code on a selected ranging opportunity for resource access to a Base Station (BS) on a shared ranging channel in a previous uplink frame. The SS also starts a time associated with the ranging code. In response to all received ranging opportunities, the BS broadcasts an acknowledgement (ACK) in a subsequent downlink frame. The ACK comprises a reception status message that indicates the decoding status of the ranging opportunities. With the novel fast feedback mechanism, when ranging collision or failure occurs, upon receiving the reception status report, the SS will proceed with the next round of contention without continuing wait for the entire timeout period. As a result, the total latency due to the ranging collision or failure is reduced. | 11-05-2009 |

20120069548 | STRUCTURE OF BACK LIGHT PLATE - A back light plate includes a plurality of light bars of high light transmittance. The light bars are juxtaposed to form a flat plate like or a grating like light emission structure. Each light bar has opposite ends to which light sources, such as light-emitting diodes, are mounted. Light emitting from the light sources can transmit through the light bar to form a uniform luminous cylinder and thereby constituting a wide span of backlighting. This arrangement saves the number of light-emitting diodes used, makes the manufacturing easy, and provides a simple and convenient-to-carry-out manufacturing process as compared to the conventional manufacturing processes of large-sized thin back light plate, so as to lead to a significant reduction of manufacturing costs. | 03-22-2012 |

20080308257 | Heat dissipating assembly - A heat dissipating assembly for dissipating heat of a heat source is provided. The heat dissipating assembly includes a body, at least one circulation pipe, and a working fluid. The body has a chamber defined therein and least one pipeline formed in a wall of the body. The body further has at least one first orifice in communication with the chamber of the body, and at least one second orifice in communication with the pipeline. The circulation pipe has two end portions respectively connected to the first orifice and the second orifice. The working fluid is accommodated in the chamber of the body, wherein the working fluid flows into the circulation pipe through the first orifice, and flows into the pipeline through the second orifice to flow back to the chamber of the body, thereby forming a two phase circulation loop. | 12-18-2008 |
