  • Publication number: 20190262201
    Abstract: A patient support apparatus may include a support surface configured to conduct air along a top face of the support surface so that heat and moisture from a patient lying on the support surface are drawn away from the top face of the support surface. An opening may be formed in a side of the support surface. A cavity may extend from the opening into the support surface. An inlet port may be positioned within the cavity and fluidly coupled to the top face. A blower assembly may be configured to position within the cavity. The blower assembly may have an outlet port that couples to the inlet port when the blower assembly is positioned within the cavity. The blower assembly may conduct air through the inlet port to the top face of the support surface.

  • Patent number: 8344970
    Abstract: A transistor control circuit (74) comprises a source-gated thin film transistor (70), an input for receiving a drive voltage representing a desired control of the source-gated transistor and a current source (82) for causing a known current to pass through the source-gated transistor (70). A first capacitor (78) stores a resulting gate-source voltage of the source-gated transistor when the known current is passed through the source-gated transistor. The drive voltage is modified using the resulting gate-source voltage, and the modified voltage is used in the control of the source-gated transistor. This control can provide a translational shift in the operating characteristics of the transistor, and it has been found that this can compensate for ageing of the transistor, for non-uniformity between different devices, and for temperature variations.

  • Patent number: 7982178
    Abstract: A photo transistor has an active region spaced from a source by barrier. A drain is laterally spaced from the active region. Light incident on the active region creates electron-hole pairs. Holes accumulate at the barrier and modulate the effective barrier height to electrons. A gate reset voltage then is applied to gate which lower the barrier allowing the holes to escape.

  • Patent number: 7763938
    Abstract: A transistor has a source electrode (22) on the opposite side of a semiconductor body layer (10) to a gate electrode (4) insulated from the body layer (10) by gate insulator (8). The source electrode (22) has a potential barrier to the semiconductor body layer (10), for example a Schottky barrier. At least one drain electrode (54) is also connected to the semiconductor body layer (10). A suitable source-drain voltage and gate voltage depletes the region of the semiconductor body layer adjacent to the source electrode (22), and then source-drain current is controlled by the gate voltage.

  • Patent number: 7569435
    Abstract: A method of making a source-gated transistor is described, in which a gate (4) is provided on substrate (2) followed by gate insulator (6) and semiconductor layer (8). The layer is patterned to align the source with the gate (4) using photoresist (12) and back illumination through the substrate (2) with the gate (4) acting as a mask. The distance between source and drain may also be self-aligned using a spacer technique.

  • Patent number: 7502001
    Abstract: In an active matrix display, each pixel has a storage capacitor for storing a voltage to be used for addressing a drive transistor. A discharge transistor is provided for discharging the storage capacitor thereby to switch off the drive transistor. The timing of this is controlled by a light-dependent device which is illuminated by the display element. The drive transistor is controlled to provide a constant light output from the display element, and the duration is controlled in dependence on the data voltage. Optical feedback is used to alter further the timing of operation of the discharge transistor to provide ageing compensation of the display element and compensation for changes in the drive transistor.

  • Patent number: 7106297
    Abstract: A color display device based on dielectrophoresis is described. The device includes a dielectrophoretic mixture comprising semi-insulating particles of each of the subtractive primary colors cyan (32), magenta (34) and yellow (36) in a semi-insulating liquid (24). The dielectrophoretic frequency characteristics of the particles are the same or similar for particles of the same color but different between the three colors. In particular, the transition frequency (f0) is different for each color, or two colors may have the same transition frequency (f0) if one has a reversed sense dielectrophoretic frequency characteristic. Also the speeds of the particles are the same for particles of the same color but different between the three colors. The pixels are driven with alternating voltages of different frequencies (f1, f2, f3, f4) and duration determined such that different proportions of the different colors of particles are moved, dependent upon their transition frequencies and speeds.

  • Patent number: 6806654
    Abstract: A matrix display has pixels 2 each including a programmable memory element 30 arranged in parallel across capacitance 28. The voltage on the capacitance controls a display element 25. The arrangement can be run in a normal mode, with all of the memory elements 30 in a high resistance state so that the matrix display can be driven dynamically. Alternatively, in a static (low power) mode of operation, the memory elements 30 are programmed with a static image which may be displayed without driving the data lines 6.

  • Patent number: 6738031
    Abstract: A matrix array display device has an array of pixels on a substrate which each have a display element, such as an electroluminescent display element. An associated control circuit including a storage capacitor and a light sensing element are connected thereto for regulating charge stored on the capacitor and responsive, for example, to light emitted from the display element so as to regulate operation of the display element. The light sensing elements include thin film semiconductor devices each having a strip of semiconductor material with laterally-spaced, doped, contact regions and the associated storage capacitor is formed by a conductive layer extending substantially transversely of the strip over one contact region with intervening dielectric material. A predetermined relationship between the storage capacitor and photosensitive device characteristics is then ensured even though dimensional variations in component layers may occur due to manufacturing tolerances.

  • Patent number: 6693610
    Abstract: An active matrix electroluminescent display device in which the drive current through an electroluminescent display element (20) in each pixel (10) in a drive period is controlled by a driving device (22) based on a drive signal applied during a preceding address period and stored as a voltage on an associated storage capacitor (36). In order to counteract the effects of display element ageing, through which the light output for a given drive signal level diminishes over time, the pixel includes electro-optic discharging means (40) coupled to the storage capacitor and responsive to the display element's light output to leak stored charge and to control the integrated light output of the display element in the drive period. For improved control, the discharging means is arranged to rapidly discharge the capacitor at a controlled point in the drive period, upon the drive of the display element falling to a low level. A photoresponsive transistor can conveniently be utilised for this purpose.
