Title: LED chess set
Inventor: SUN CHING-CHERNG
IPC: A63F3/02
Filed: 2008-06-26
Abstract: This invention discloses a light emitting diode (LED) chess set. When a chess piece of the chess set is placed on a chessboard, a power supply element in the chessboard will supply power to an LED in the chess piece to emit light, so that the chess piece gives a light emitting effect. When a player removes a chess piece from a square of the chessboard for a next movement of the chess piece, a control element in the chessboard will identify an identification element of the chess piece through a sensing element on the square to determine any possible next movement of the chess piece on the chessboard and drive the LEDs in the corresponding squares of all suggested movements to emit light. The light-emitting square guides and suggests players to make the next movement of a chess piece and improve a beginner's memory on the rules of chess.

Title: Feedback and rate adaptation for MIMO transmission in a time division duplexed (TDD) communication system
Inventor: XU HAO
IPC: H04L25/03
Filed: 2008-08-13
Abstract: Techniques for sending a MIMO transmission in a wireless communication system are described. In one design, a transmitter sends a first reference signal to a receiver. The receiver selects a precoding matrix based on the first reference signal and in accordance with a selection criterion. The receiver estimates noise and interference at the receiver and determines channel quality indicator (CQI) or modulation and coding scheme (MCS) information based on the precoding matrix and the estimated noise and interference. The receiver sends the CQI or MCS information and a second reference signal to the transmitter. The transmitter selects the precoding matrix based on the second reference signal and in accordance with the same selection criterion used by the receiver. The transmitter then sends a MIMO transmission to the receiver based on the CQI or MCS information obtained from the receiver and the precoding matrix selected by the transmitter.

IPC: H01L21/30
Filed: 2009-01-22
Abstract: This invention relates to a tin/silver bonding structure and its method. It primarily utilizes tin and silver as a bonding layer between wafers. The stress released by inter-diffusion bonding between tin and silver is greater than the stress released by inter-diffusion bonding between gold and silver as known in the prior art.

Title: Light source for illumination and the pattern inspection apparatus using the same
Inventor: NOMOTO KENTARO
IPC: G01B11/30
Filed: 2009-02-09
Abstract: The subject of the invention is to provide a means for illuminating any point within a photographing field at the same incident angle, and a pattern inspection apparatus capable of determining whether pits are good or not. To solve the problem, plural LEDs are arranged along an LED support part (3), and the illumination beams are emitted from the LEDs in parallel, thereby constituting each planar light source a-h incident at a specific angle <theta> to the photographing field (R). The field for arranging the LEDs is larger than the photographing field (R). The illumination beams are emitted from the eight planar light sources a-h in a parallel way, thereby entering the whole photographing field (R) at a specific angle <theta>. Therefore, at any point on BAC within a photographing field (R), illumination beams of the same angle are incident with the same intensity from all directions, resulting in the same condition for any point on the photographing field. Therefore, it is able to determine whether the whole field under inspection is good or not based on the brightness (luminescence) difference of the pits.

IPC: F16B5/02
Filed: 2009-04-01
Abstract: The present invention provides a fastening device, which includes a butt sleeve, a fixing element, an external casing pipe, and a spring. The front end of butt sleeve is formed with a fastening portion, and the rear end on the other side away from the fastening portion is formed with an annular protrusion portion, so that the fastening portion of butt sleeve is firstly inserted into a combination aperture formed on the surface of a first sheet block, and fastened into an integral body by using the solder paste from a reflow process. Next, the spring is covered on a pre-specified position of a stem body of the fixing element. Furthermore, the external side of fixing element is positioned by a stop formed by alignment compression of more than one annular resist portions on the front opening of external casing pipe formed by plastic injection molding with the annular protrusion portion of butt sleeve. This configuration prevents problems, such as discoloring, softening, etc. occurred on the external casing pipe due to over-heating when the external casing pipe goes through a reflow oven. Meanwhile, the spring can be prevented from the problem of high temperature annealing, thereby ensuring good elastic deformation functions. Furthermore, the butt sleeve can be connected to a material belt so that the production line will not be interrupted, and the invention has the advantages of being convenient in the retrieval of components, mass production, increased yield, and reduced production cost.
