Title: In-home theater surround sound speaker system
Inventor: RUZICKA JEROME E
IPC: H04N7/24
Filed: 1997-07-25
Granted: 2000-06-21
Abstract: An apparatus for realistically reproducing sound, particularly for sound based on a stereophonic signal having dialog and effects and associated with an accompanying video image. The apparatus includes a front speaker located in proximity to the video image for providing acoustic output based upon a summation signal of the component left and right (L+R) channels of the audio signal. A rear speaker located to the rear of the viewing area provides acoustic output based upon a difference signal, (L-R) or (R-L), between the left and right channels. Left and right speakers located to the respective left and right sides of the viewing area. The left and right channels speakers reproduce in one embodiment the respective left and right channels of the audio signal and in a second embodiment reproduce a difference signal, (L-<beta>R) or (R-<beta>L), where <beta> is a gain which may vary or may be a value fixed between zero and unity. Output to the left and right speakers is band limited to substantially filter out frequency components below a predetermined threshold. A bass speaker may also be provided to output the low frequency components of a (L+R) summation signal. The (L+R) summation signal input to the front speaker assists in localizing dialog to the video image. The (L-<beta>R) or (R-<beta>L) difference signal substantially removes dialog sound so that the side and rear speaker output primarily comprises sonic ambience and surround sound effects. Band limiting the left and right speakers further assists in localizing dialog to the video image. Alternatively, in yet another embodiment, a monophonic signal may be applied to at least one embodiment of the system to enable production of a spatially enhanced surround sound effect.

Title: Laser machining method
Inventor: YUYAMA TAKAYUKI
IPC: B23K26/382
Filed: 1997-12-06
Granted: 2001-07-21
Abstract: The present invention provides a spacing hole machining method of printed board for the purpose of high quality and good productivity. During the laser machining of compound materials such as those mixed with epoxy resin or glass epoxy resin (tempered epoxy resin of glass fiber) of glass cloth (glass fiber cloth), it is necessary to shorten the mutual reaction time to get high quality machining results, a certain number of waiting time is required to cool down the machining material in the irradiated interval between the pulsed beams. But in order to increase the productivity, it is necessary to shorten the cooling time. In the present invention, a laser beam with a prespecified oscillation frequency is divided into an arbitrary number of pulses to be irradiated to all holes in an area of hole opening, and this step is repeated until the irradiation reaches a desired number of pulses, whereby an interactive time can be decided according to the number of divided pulses and a cooling period of time can be obtained, and also the number of pulses per one division is set to be a plurality of pulses, which allows an etching rate to be increased, so that the number of pulses required for machining can be reduced as compared to the case where all the holes are irradiated by laser pulses one by one.

IPC: G09G3/32
Filed: 1998-01-26
Granted: 2001-06-16
Abstract: A controller stores image signals Sp represented as binary values for every unit of frame. The controller divides one frame into a plurality of sub-frames representing an image by image data of two gradation levels, in accordance with respective figures of the stored image signals Sp for one frame. The image data of two gradation levels for each of the sub-frames is written into capacitors Cp from a drain driver, for every row. When the image data is ""1"", a drive transistor is turned on. A common driver applies a voltage of a predetermined level for every sub-frame, to control the voltage applied between electrodes of an organic EL element. As a result, the organic EL element emit light with brightness which differs between sub-frames. Images of the sub-frames are visually synthesized, so that gradation is expressed in one frame.

Title: Video camera system
Inventor: NEWMAN EDWARD GEORGE
IPC: G03B3/12
Filed: 1998-11-02
Granted: 1999-06-11
Abstract: This invention involves the use of a body worn mobile computer with a video camera to allow image alignment. Quite frequently a video camera user cannot look directly into the camera because of some obstruction. In these cases, in order to be sure the camera is pointed in the right direction and toward the object to be captured by the image, a head mounted display worn by the user and connected to a computer can simplify this process. An example of where this system can be used is when the camera operator is located in the rear of a crowd watching a parade. He or she can hold the camera viewer above the crowd and view the image in their head mounted display thereby moving the camera viewer in the desired direction. The visible image can then be simultaneously displayed to the wearer (or user) and stored or recorded on the wearable computer or even transmitted via the computer peripherals to a remote location.
