Title: Method and apparatus for calibrating a tiled display
Inventor: CHEN CHUNG-JEN
IPC: G09G3/34
Filed: 1999-09-23
Abstract: A display system that can be calibrated and re-calibrated with a minimal amount of manual intervention. To accomplish this, one or more cameras are provided to capture an image of the display screen. The resulting captured image is processed to identify any non-desirable characteristics, including visible artifacts such as seams, bands, rings, etc. Once the non-desirable characteristics are identified, an appropriate transformation function is determined. The transformation function is used to pre-warp the input video signal that is provided to the display such that the non-desirable characteristics are reduced or eliminated from the display. The transformati on function preferably compensates for spatial non-uniformity, color non- uniformity, luminance non-uniformity, and other visible artifacts.

Inventor: NOLL CHARLES G
IPC: H05F3/06
Filed: 2001-06-13
Abstract: An ionizer creates a corona current distribution having a balanced flow of positive and negative ions in a variable ion mobility gaseous environment. The balanced flow of positive and negative ions are directed toward a workspace or target located in the gaseous environment and downstream from the ionizer. The ionizer includes a corona electrode, a counterelectrode, a corona-free dc bias electrode, and a control circuit. The corona electrode has a negative polarity. The counterelectrode has an ion collecting surface.  The corona-free dc bias electrode has a positive polarity. The control circuit controls the output of the corona-free electrode so as to cause a balanced flow of positive and negative ions to be emitted from the ionizer and directed towards the workspace or target. In this manner, a static-free environment is created at the workspace or target.

Title: Space-time processing for wireless systems with multiple transmit and receive antennas
Inventor: VALENZUELA REINALDO A
IPC: H04B7/08
Filed: 2001-06-19
Abstract: Signals are developed for use in a wireless system with multiple transmit and multiple receive antennas so that even in the face of some correlation the most open-loop capacity that can be achieved using a substantially open-loop system with a channel of that level of correlation is obtained. In accordance with the principles of the invention, the signals transmitted from the various antennas are processed so as to improve their ability to convey the maximum amount of information. More specifically, the data to be transmitted is divided into M+1 substreams, where M is the number of transmit antennas. Each transmit antenna is supplied with a combination signal that is made up of a weighted version of a common one of the substreams and a weighted version of a respective one of the substreams that is supplied uniquely for that antenna, so that there are M transmit signals. A receiver having N antennas receives the M transmit signals as combined by the channel and reconstitutes the original data therefrom. This may be achieved using successive decoding techniques. Advantageously, the capacity, i.e., the . rate of information that can be conveyed with an arbitrarily small probability of error when the instantaneous forward channel condition is unknown to the transmitter, is maximized.
