Abstract: An integrated circuit die may have a processor and a spatial light modulator formed in the same die. An opening may be provided in an interposer to allow light to reach the spatial light modulator. A plurality of bump bonds may space the interposer from the die region including the processor. Thus, a display may be formed in an integrated fashion with a processor.

Abstract: An integrated circuit may have a spatial light modulator formed on one side of a semiconductor support and a microprocessor formed on the opposite side. The microprocessor and the spatial light modulator may communicate with one another through electrical connections which extend completely through the semiconductor support. The microprocessor may be contacted using bump packaging techniques.

Abstract: An electronic system includes an antenna, a time of day circuit, a second circuit and a processor. The antenna receives a first indication of a time of day, and the time of day circuit is adapted to furnish a second indication of a time of day. The second circuit is adapted to calibrate the time of day circuit based on the first indication, and the processor is adapted to use the second indication to time stamp operations of the system.

Abstract: A projection display system may be mechanically perturbed to remove or reduce speckle. In addition, pixellation effects may also be removed or reduced. By mechanically disturbing a portion of the system, for example using a wobble perturbation, the speckle effects may be temporally smeared so that they become invisible to the user. In one embodiment of the present invention, a folding mirror may be mechanically perturbed, using a plurality of piezoelectric actuators, at frequencies in the ultrasonic range.

Abstract: A close-up imaging device may take advantage of the pinhole effect that may be achieved with complementary metal oxide semiconductor imaging arrays. In particular, a high magnification optical lens may be placed at a distance from the imaging array which is less than the focal length of the device. In this way, a relatively compact, low cost imaging device may be used for close-up imaging applications such as fingerprint scanning or text reading.

Abstract: In calibrating displays, analog information may be converted into digital information to control the display. The requirements of the analog to digital converter may be decreased by decreasing the necessary dynamic range for the analog to digital converter. This may be done by developing a first calibration signal indicative of a first plurality of pixels of the display and developing a second calibration signal indicative of a second plurality of the display. The first and second signals may be subtracted from each other and that signal may then be converted to a digital signal with reduced dynamic range requirements for the analog to digital converter.

Abstract: A projection system includes display panels, optics and an adjustment device. Each display panel is adapted to modulate a different beam of light to form an associated modulated beam of light. The optics are adapted to form an associated image of each modulated beam of light, and the adjustment device is adapted to position one of the display panels to adjust convergence of the images.

Abstract: A system includes an array of pixel cells, column lines, storage elements and decoding circuitry. The pixel cells are arranged in rows and columns and the column lines are associated with the column pixel cells. The storage elements are associated with a row of the pixel cells. The decoding circuitry is adapted to storage charges on the column lines and after the storage, transfer the charges from the column lines to the storage elements.

Abstract: An extended color polymer display has light emitting elements of more than three colors. Tricolor color spaces are selected for color transformations from known color spaces such as sRGB. The color transformations may take into account not only the best implementation of the color scheme but also considerations related to computational complexity and power consumption reduction.

Abstract: A luminosity channel may be provided in an electro-optic projection display by beam splitting the incident light source into first and second polarization beams. One polarization beam may be used to illuminate the three modulators for the three primary color channels. The other beam may be utilized to illuminate a white light modulator which provides a luminosity channel. The two beams may be recombined to produce the final image. As a result, in some embodiments, higher resolution, or wider color gamut, and better image quality may be achieved without unduly effecting the light efficiency of the display.

Abstract: A system for measuring the convergence alignment may include an optical system arranged to preferentially image and magnify the regions of a display screen outside the area normally viewed by users. That area may include convergence targets which may be associated with each corner of the display. That information may be provided as a unified image to an imaging sensor which may thereafter be utilized to analyze the information and if desired, make appropriate corrections.

Abstract: Rotational motion about at least two different axes may be resolved to measure the direction, magnitude and pivot point of the rotational displacements In some embodiments, these measurements may be made by a device which may be integrated into a silicon substrate using conventional silicon processing techniques. For example, a pair of accelerometers may be formed by a pair of cantilevered beam arrays. Rotational displacement of a camera imaging sensor, for example, may use such accelerometers integrated into the same silicon substrate forming the imaging sensor.

Abstract: A lens cover for a digital camera provides a diffused light source for calibration purposes which approximates a flat field light source. In this way, digital cameras may be calibrated in the field under user control. The diffuser may be in the form of a light transmissive hologram. The hologram may have formed thereon a plurality of light diffusing shapes. The camera may be calibrated either by itself or advantageously when connected to a host computer. The user may be prompted through the calibration sequence.

Abstract: The degradation of less than all of the pixels of a polymer display may be monitored and the uniformity of the display may be adjusted by either overdriving a given pixel or reducing the light output of other pixels in the display. In this way, the display's lifetime may be maximized without incurring pixel non-uniformity. In addition, the characteristics of the display may be monitored over time in order to provide the user with an early warning of imminent display failure.

A valve on the air tank is opened automatically when the tank is threaded to a rigid fitting carried on the mask. The valve body is equipped with a rupture film which ruptures to vent excessive pressure in the dispensing system.
