    Abstract: There is described a method as well as a device for motion detect ion in an optical sensing device, such as an optical mouse. A photodetector array comprising a plurality of pixels is used to detect successive light intensity patterns of an illuminated portion of a surface with respect to which a measurement of relative motion is to be determined. Light intensity between neighbouring pixels is compared in order to determine edge direction data descriptive of light intensity differences between the pixels, such data including (i) a first edge condition, or positive edge, defined as a condition wherein light intensity of a first pixel is less than light intensity of a second pixel, and (ii) a second edge condition, or negative edge, defined as a condition wherein light intensity of the first pixel is greater than light intensity of the second pixel. Through comparison of this edge direction data with edge direction data determined from a previous illumination (or by comparing data extracted from this edge direction data) a measurement of the relative motion of the optical sensing device with respect to the illuminated portion of the surface is determined.

    Abstract: A tiled display device is formed from display tiles having picture element (pixel) positions defined up to the edge of the tiles. Each pixel position has an organic light-emitting diode (OLED) active area which occupies approximately 25 percent of the pixel area. Each tile includes a memory which stores display data, and pixel driving circuitry which controls the scanning and illumination of the pixels on the tile. The pixel driving circuitry is located on the back side of the tile and connections to pixel electrodes on the front side of the tile are made by vias which pass through portions of selected ones of the pixel areas which are not occupied by the active pixel material. The tiles are to formed in two parts, an electronics section and a display section. Each of these parts includes connecting pads which cover several pixel positions. Each connecting pad makes an electrical connection to only one row electrode or column electrode. The connecting pads on the display section are electrically connected and physically joined to corresponding connecting pads on the electronics section to form a complete tile. Each tile has a glass substrate on the front of the tile. Black matrix lines are formed on the front of the glass substrate and the tiles are joined by mullions which have the same appearance as the black-matrix lines. Alternatively, the black matrix lines may be formed on the inside surface of an optical integrating plate and the tiles may be affixed to the integrating plate such that the edges of the joined tiles are covered by the black-matrix lines. A cathodoluminescent tile structure is formed from individual tiles that have multiple phosphor areas, a single emissive cathode and horizontal and vertical electrostatic deflecting grids which deflect the electron beam produced by the single cathode onto multiple ones of the phosphor areas.

    Abstract: There is described a method, a sensing device as well as an optical pointing device including a sensing device for comparing light intensity between pixels. Light intensity between pairs of pixels of a photodetector array is compared as follows. First and second output signals generated by the photosensitive elements of a first and a second pixel of each pair are integrated over time to respectively provide first and second integrated signals. Integration of the first output signal is interrupted at the end of a first time period and the resulting first integrated signal is stored. Integration of the second output signal is continued until the end of a second time period and the resulting second integrated signal is compared to the stored first integrated signal to provide an output signal representative of an edge condition between the first and second pixel.

    Abstract: The present invention is directed toward an improved heater chip for an ink jet printer. The heater chip has a diamond-like-carbon coating that functions as the cavitation and passivation layers of the heating elements on the heater chip. To improve the efficiency of the heater chip, the diamond-like-carbon coating is surrounded by a material that has a lower thermal conductivity than diamond. This surrounding layer limits thermal diffusion from the heating elements into the heater chip. A smoothing layer of tantalum is deposited over the diamond-like-carbon layer to insure that vaporization of the ink occurs at the ink's superheat limit. The diamond-like-carbon layer is preferably less than 8700 Angstroms in thickness such that less than 1 microjoule of energy is required to expel of ink droplet having a mass between 2-4 nanograms.

    Abstract: A dynamoelectric machine has a stator member, a rotor member, a first shroud and a second shroud. The first shroud and the second shroud members are mounted to the rotor adjacent respective first and second end portions of the rotor for rotation with the rotor. The first and second shrouds extend radially over and are spaced from the respective radially extending first and second end portions of the rotor to respectively define radial inlet and outlet paths therewith. The first and second shrouds each have a first radially inner end adjacent and spaced from the shaft to define a gas inlet or outlet, respectively, and a second radial outer end mounted to the rotor adjacent and spaced apart the ventilation ducts for communicating gas between the ventilation ducts and the inlet and outlet paths. The second outlet shroud is spaced further from the shaft than the inlet shroud so as to facilitate the gas flowing in the inlet shroud and out the outlet shroud during normal machine operation. Fan motors are provided at the inlet and outlet of the shrouds to direct gas flow. The present invention provides for an improvement in windage loss by angularly accelerating the gas prior to entering the ventilation ducts of the rotor and an additional improvement by partially reclaiming energy at the outlet shroud energy by angularly decelerating the gas flow.

    Abstract: A display device having features which enhance the contrast of displayed images includes a pixel structure that defines an active pixel area and an inactive pixel area. The display device may be an emissive device such as an OLED or electroluminescent device, a transmissive device such as a liquid crystal light-valve device or a reflective device, such as a Bistable, Reflective Cholesteric (BRC) liquid crystal device. The ratio of the active pixel area to the total pixel area is less than 50 percent. The display device includes a transparent cover plate having a black matrix formed on the viewer side of the cover plate. The display device may be a tiled display in which case the black matrix is formed on an integrator plate to which the individual tiles are bound to form the complete display device. For reflective or emissive display materials, the display device includes an electronics section including a circuit board which provides driving signals for the pixels of the display device. The electronics section is bound to the display section by an adhesive. To provide a light-absorptive background for the active pixel elements, the circuit board or the adhesive are colored black. The individual pixel elements of the display device include four sub-pixel components separated by portions of the inactive pixel area, which four sub-pixel components together define the active area of the pixel. A lens system is provided on the viewer surface of the display to concentrate light emitted by the active area of the pixel elements into a smaller area, thus decreasing the aperture of the display. Areas between the lenses on the viewer surface of the display are coated with a black material to form a black matrix. A black material is selectively deposited on the front cover plate before applying the metal row electrodes to prevent the row electrodes from providing a reflective surface to the viewer.
