Title: Overshoot control and damping circuit for high speed drivers
Inventor: HOJABLI PEYMAN
IPC: H03K17/16
Filed: 1999-06-21
Granted: 2003-09-01
Abstract: An overshoot and damping control circuit for high speed L-R-C drivers. By properly configuring four transistors in conjunction with a high speed driver, negative feedback can be utilized to generate a spike of current to correct for overshoot which results when driving an inductive load with high speed signals. This same configuration also provides the additional benefit of providing a signal which dampens the ringing which results from driving an inductive load with a high speed signal.

Title: Spreader for multiple data rates
Inventor: NIEGEL MICHAEL
IPC: H04J13/00
Filed: 1999-07-20
Granted: 2001-05-01
Abstract: The present invention relates to spreading data of a plurality of digital communication channels having different data rates with code sequences having different lengths. The inventive circuit allows to use a single hardware unit for spreading communication channels having different data rates, e.g. in a CDMA telecommunications system. This is achieved by processing either a single symbol and a corresponding long code in appropriate storage means for a channel with a lowest rate or to process a plurality of symbols and corresponding shorter code sequences of communication channels having higher data rates. Thus, a joint chip rate after spreading is obtained using a single hardware structure.

Title: Metallization process for growing high-quality copper with a high selectivity
Inventor: CHEN SHENG-SHIUNG
IPC: H01L21/768
Filed: 1999-08-24
Granted: 2001-07-01
Abstract: A metallization process comprises forming a trench in the insulator layer; uniformly depositing a barrier film layer on the insulating layer and on the surface of the trench by chemical or physical vapor deposition; forming a seed layer suitable for forming a copper film on the surface of the barrier layer, so that the seed layer is easy to be adhered. In order to restrict the formation area of the subsequent conductive film, the present invention removes the seed layer located above the insulating layer in advance. For example, the seed layer located above the insulating layer is removed by chemical mechanical polishing process, while the seed layer located on the surface of the trench is reserved. Finally, the copper is formed by ECD manner. The copper is selectively formed on the region of the trench, and has a flat metal surface.

Title: Method to compensate for the color no uniformity of color display
Inventor: WEN SHENG-FA
IPC: G09G3/20
Filed: 2000-01-06
Granted: 2002-03-21
Abstract: The present invention relates to a method to compensate for the color no uniformity of color display. If the color coordinates of the primaries of each pixel in the display are not the same, the expressed color will be non-uniform. A set of virtual primaries can be selected from the distribution of primary color coordinates, so that the primaries of each pixel (or called initial primary) can generate this virtual primary. Replacing the virtual primary by the initial primary can make the expressed color of display be uniform, since the color coordinates of the virtual primary of each pixel are the same. This method is called virtual primary method. To describe this method, a light-emitting diode display is used as an example. Let the tri-color stimulus of the LED of the initial primaries in a pixel be equal to the tri-color stimulus of the virtual primaries, the formula to convert the inputted signal into modulated signal of LED can be obtained from this condition. The system constructed from this formula can resolve the non-uniform color problem of LED display without rigorous selection to LED to ensure the uniformity of color.

Abstract: A device network (10) to process signals has target devices (12, 14), selecting devices (16) that are movable relative to the target devices (12, 14), and controllers (18). The controllers (18) are in communication with the target devices (12, 14) and the selecting devices (16).

Each of the selecting devices (16) also has a signal processor to generate a control signal having the position and orientation data. This control signal is then transmitted by a transmitter, via a radio frequency channel (24a), to a controller (18a). Upon receiving the control signal, the controller (18a) determines whether, for example, a target device (12a) has been selected by a selecting device (16a) by comparison of the orientation data with a derived orientation based on the position data and the known position of the target devices.
