摘要： A control system for a cooling fan of a laser printer enables selection of fan speed based on the actual degree of usage of the printer. The system provides first and second sets of fan speeds where each set contains information corresponding to a plurality of fan speeds. Information regarding the current operational condition of the fuser of the printer is periodically obtained, preferably during a preset interval. The fan is then operated at one of the fan speeds of the first or second set of fan speeds, with the selection of the first or second set and the selection of one of the fan speeds based on the current operational condition of the fuser. In this manner, the speed of the fan is substantially continuously controlled based on the operational condition of the printer.

摘要： A phase spatial light modulator composed of a first liquid crystal cell and one or more additional liquid crystal cells. Each of the liquid crystal cells is positioned so that their extraordinary optical axis (N.sub.e) lies orthogonal to the next liquid crystal cell, and the group of cells is positioned along the optical axis of light emitted by an image source. The modulator, or scanner, thereby capable of steering substantially 100% of unpolarized light therethrough. The modulator intended for use within a display system additionally composed of an image source, driver/control circuitry and an optical magnification system. In operation, an external stimulus is applied, such as a voltage supplied by an external power source, thereby spatially changing the phase of light emitted therethrough. The scanning action enhances display resolution of the generated resultant image without an increase in the number of pixels of the image source.

摘要： A phase spatial light modulator composed of a liquid crystal cell and a reflective element. The modulator capable of receiving and modulating substantially 100% of unpolarized light impinging thereupon. The modulator intended for use within an electro-optical system additionally composed of a light source, driver/control circuitry and an optional optical magnification system. In operation, an external stimulus is applied, such as a voltage supplied by an external power source, thereby changing the phase of light emitted therethrough, generating two beams of light traveling in different directions. The first beam of light impinges upon the reflective element and is reflected to travel in the same directional path as the second beam of light.

摘要： A method of fabricating an active matrix LED array includes forming layers of material on a substrate, which layers cooperate to emit light when activated. Row and column dividers are formed in the layers to divide the layers into an array of LEDs arranged in rows and columns. One FET is formed on the row dividers in association with each LED and a source of each FET is connected to an anode of the associated LED. Row and column buses are formed on the row and column dividers, respectively, and the drain of each FET is connected to an adjacent row bus with the gate of each FET being connected to an adjacent column bus. A cathode for each LED is connected as a common terminal for all of the LEDs in the array.

摘要： A phase spatial light modulator composed of a liquid crystal cell having molecular orientation recorded during the fabrication process as a direct result of a photochemical reaction exerted upon the liquid crystal material, a mechanically-induced change of a liquid crystal alignment layer, or by varying a plurality of polymer materials that compose the liquid crystal alignment layer, thereby affecting the liquid crystal material contained within the cell. The modulator, or scanner, thereby capable of altering the phase, thus steering light passing therethrough. During operation, the liquid crystal molecules deflect the light beam passing therethrough based on their orientation as recorded during fabrication when the applied voltage is "OFF" or in an altered state when the applied voltage is "ON".
