Abstract: The object of the present invention is to provide an antenna pair that has the advantages of easy installation and improved gain. According to the present invention, the antenna pair consists of two slot antennas formed on a metallic strip and sharing a common portion of the strip as the grounding unit. The grounding portions of the antennas join together to become the grounding unit so as to increase the effective antenna aperture for both of the antennas and to raise their gains. As the antennas are combined into one, it is more manageable and handy for installation. The grounding unit can be further extended to allow greater improvement. The strip on which the slot antennas are formed is curved to have the antennas orthogonal to each other. The orthogonality brings about the space diversity effect and prevents the occurrence of any null in the radiation pattern of the antennas.

Abstract: To suppress light loss without deteriorating resolution of a projected image, light is first polarized and separated by a polarizing beam splitter. Green light is separated from a light flux emitted by the polarizing beam splitter by a dichroic mirror having a green light reflection property. A light flux containing blue and red light, which is transmitted by the dichroic mirror, is separated into red light and blue light by a dichroic prism. Resultant color light is modulated and reflected by reflection light valves, returned to the corresponding dichroic mirror or dichroic prism, and combined by the dichroic mirror and the dichroic prism. Resultant combined color light is projected via the polarizing beam splitter and a projection lens. The dichroic prism transmits s-polarized light having wavelengths less than a wavelength substantially within a wavelength band of green light and reflects s-polarized light having larger wavelengths.

Abstract: A three electrode plasma display panel (PDP) operates in concurrent sustain and addressing periods, rather than separating the sustain and addressing periods. Because of this concurrent operation, a PDP with a brighter display is produced. Crosstalk between sustain electrodes and the column electrodes of non-selected rows is mitigated by implementing column voltages such that there is no difference in crosstalk brightness levels in non-addressed pixels in the on state compared to non-addressed pixels in the off state. This is accomplished by choosing column voltages that are approximately symmetric about one-half of the sustain voltage.

Abstract: An active matrix display that does not require a transistor or similar current switching device at each pixel.

Each pixel further includes a thermoelectric heat transfer circuit which transfers heat to or from the sensor in an amount which varies in response to the video signal. Consequently, the video signal controls the temperature of the sensor within a pixel's temperature-controlled current source, which controls the current flow through the pixel's field emitters.

The time duration of the inverse image portion is shorter than the time duration of the image portion by an amount proportional to the increased magnitude of the additional electric fields.

Abstract: This invention provides a method and apparatus to selectively compress digital image data for the supply of that information to digital display screens or storage. The invention utilizes a digital input containing a non-linear representation between the value and the intended intensity and linearizes this into a higher order number. If the higher order number is below at least a first threshold, it is transmitted or stored on a lower order data system noting that the higher order bits or channels should all be zero. If the higher order value is above the threshold, the highest order bits of that value are transmitted or stored on the lower order data system so that only the lowest order bits are lost. The received input from the lower order data system can then be decoded and the data sent to drive a digital display or otherwise utilized.

Abstract: A method and apparatus for clipping an object element include processing that begins by ascribing barycentric coordinates to each original vertices of an object-element wherein each barycentric coordinate is a weighting factor with respect to a corresponding original vertex. The processing continues by obtaining clipping distances for each original vertex with respect to a clipping plane.

The determination of the new vertex is based on the barycentric coordinates of the original vertices defining the edge and the clipping distances. Having determined the barycentric coordinates for the new vertices corresponding to a clipping plane, the process is repeated for each of a plurality of other clipping planes that intersect the object-element.
