Abstract: A head-coupled display device for use in presenting electronically generated visual images to a viewer. The device includes a headpiece worn by a viewer, and an image display screen mounted in the headpiece for presenting electronically generated images. A fresnel lens is positioned adjacent the screen for focusing images from the screen at a selected position for viewing as a virtual image. The lens has a set of concentric converging rings whose surface curvatures act to minimize rectilinear distortion of the virtual images perceived by the viewer over the entire field of view of the image.

Abstract: A display adapted for use in head mounted display systems. The display includes an array of reflecting pixels, a first light source for illuminating the array of reflecting pixels, and a mask screen located between the light source and the array of reflecting pixels. The mask screen includes a plurality of mask elements, one mask element corresponding to each of the pixels. The mask elements have a first state in which the mask element is transparent and a second state in which the mask element is opaque. The state of the mask element is determined by a potential generated by the corresponding pixel. Each of the pixels includes a reflector for reflecting light from the first light source into a cone having an opening angle and an axis which depends on the position of the pixel in the display and on the telecentricity of the imaging optic. In the preferred embodiment of the present invention, each of the reflectors is an off-axis portion of a diffractive micro Fresnel mirror.

Abstract: An apparatus and method a method for performing two-pass real time video compression is provided. Tactical decisions such as encoding and quantization values are determined in software, whereas functional execution steps are performed in hardware. By appropriately apportioning the tasks between software and hardware, the benefits of each type of processing are exploited, while minimizing both hardware complexity and data transfer requirements. One key concept that allows the compression unit to operate in real time is that the architecture and pipelining both allow for B frames to be executed out of order. By buffering B frames, two-pass motion estimation techniques can be performed to tailor bit usage to the requirements of the frame, and thereby provide a more appealing output image.

Abstract: The present invention relates to a projection type image displaying apparatus capable of displaying larger picture images which are bright, uniform and after-image-free.

Abstract: An AC plasma panel display includes front and back panels that respectively support a first parallel electrode pattern and a second orthogonally oriented, parallel electrode pattern. The electrode patterns define a display area and both patterns are covered by dielectric layers. A dischargeable gas is positioned between the dielectric layers in the known manner. Driver circuitry is coupled to both electrode patterns for creating a spatially continuous gas discharge along at least one continuous electrode of one electrode pattern and across the entire display area. The driver circuitry scans the spatially continuous gas discharge across remaining parallel electrodes of the one electrode pattern so as to scan the entire display area. A further electrode is in DC conductive communication with the gas and is positioned outside of the display area but in contact with the spatially continuous gas discharge during its scanning action.

Abstract: A finger rest structure of computer mouse, including a housing having a profile substantially suitable for manual operation of a user and a finger rest unit including at least one rest plate transversely projecting from a lateral side of the housing for a finger to rest thereon. Two rest plates are respectively disposed on left and right sides of the housing near front and rear ends. Alternatively, the rest plate is integrally connected along the rear side and a part of lateral side of the housing. Alternatively, the rest plates are pivotally and foldably connected with the housing or disposed at two ends of a rotary plate which is rotatably disposed under the housing, whereby the rest plate can be selectively extended or retracted. The rest plate serves to bear most of the weight of the hand and reduce the frictional force of the hand against the table face.

Abstract: A system and method for optically, serially transmitting data to a remote device using an interlaced display device. The data bits to be transmitted are ordered so that the bits are received in proper temporal order by the remote device. At least one of the data bits can be transmitted using the even-numbered horizontal scan lines of the interlaced display device. If all of the data bits can not be transmitted using the even-numbered horizontal scan lines of a usable transmission area, then at least one of the data bits can be transmitted using the odd-numbered horizontal scan lines of the interlaced display device. The binary data bits can be represented by illuminated and non-illuminated horizontal scan lines. An optical detector in the remote device can be used to receive the pulses of light, representing the data bits to be transmitted, from the horizontal scan lines.

Abstract: Disclosed is a method to image events with a camera having a focal plane ay of sensors on a charge coupled device whose parallel vertical registers clock signal charges to a horizontal register. The method includes sending a first clock signal to first gates on vertical register zones proximal to the sensors, and sending a second clock signal to second gates on distal vertical register zones remote from the sensors. A first transfer pulse on the first clock signal causes first signal charges in the sensors to transfer to the proximal zones, and then the first signal charges dissipate into the substrate of the charge coupled device. A second transfer pulse of the first clock signal occurs at a predetermined interval after the first transfer pulse and second signal charges transfer to the proximal zone. The second signal charges are clocked off the charge coupled device to become part of a video signal.
