Title: Cursor pointing device in vibration control
Inventor: CHEN SHOEI-LAI
IPC: G06F3/02
Filed: 2004-02-11
Abstract: A cursor pointing device can be operated on a surface or a space to control the cursor on a computer display. A vibration sensor is used as a sensor to detect and translate the two-dimensional motion of the cursor pointing device. The vibration sensor is a two-axis accelerometer. When there is a movement of the cursor pointing device, a positioning signal can be generated by calculating the acceleration and the direction of the movement to be sent to the computer.

Title: Voltage dimmable led display producing multiple colors
Inventor: COLEY CRAIG J
IPC: H05B44/00
Filed: 2002-09-04
Abstract: Multi-color illumination for a single display 110 is achieved by utilizing a n array 104 of white light emitting diodes to produce illumination optically filtered by separate filters 107a-107d to produce the two or more desired output illumination colors at a desired luminance when the full rated voltag e is applied to the light emitting diodes 104. Since all of the light emitting diodes 104 have the same bandgap, voltage-controlled dimming produces unifor m luminance changes for all colors as the voltage is reduced. A single voltage - controlled dimming driver circuit design 200 and a single control voltage ma y therefore be utilized to achieve desired and uniform dimming characteristics independent of output illumination color.

Title: Multi-mode terminal in a wireless mimo system with spatial multiplexing
Inventor: WALLACE MARK S
IPC: H04B7/04
Filed: 2003-10-24
Abstract: A user terminal supports multiple spatial multiplexing (SM) modes such as a steered mode and a non-steered mode. For data transmission, multiple data streams are coded and modulated in accordance with their selected rates to obtain multiple data symbol streams. These streams are then spatially processed in accordance with a selected SM mode (e.g., with a matrix of steering vectors for the steered mode and with the identity matrix for the n on- steered mode) to obtain multiple transmit symbol streams for transmission fr om multiple antennas. For data reception, multiple received symbol streams are spatially processed in accordance with the selected SM mode (e.g., with a matrix of eigenvectors for the steered mode and with a spatial filter matrix for the non-steered mode) to obtain multiple recovered data symbol streams. These streams are demodulated and decoded in accordance with their selected rates to obtain multiple decoded data streams.
