  • Patent number: 10429036
    Abstract: The invention described herein is a very thin flat panel LED luminaire, including a flat baseboard, a flat reflection panel, a flat acrylic panel, a flat diffusion panel, LED bar, and aluminum encasement frame which combines with the baseboard to form the chassis for the luminaire. The LED bar is placed along either or both sides of the stack. The acrylic panel is printed with a mesh-like mask pattern of dots in a pattern in which the density of the pattern is decreases the farther away from the LED bar the pattern is, differentially coupling the light from the point source LED bar from the reflection panel into the flat acrylic panel so that illumination across the luminaire is substantially uniform.

  • Patent number: 7487488
    Abstract: A mechanism is disclosed for assigning repeaters to signal paths in an integrated circuit design. The mechanism involves reserving, in a first metal layer of the integrated circuit design, metal tracks for routing signals. Access points to a plurality of repeaters are reserved in a second metal layer of the integrated circuit design. Each access point is associated with a particular repeater. The design may have other layers between the second metal layer and a region reserved for the repeaters. The number of repeaters may be based on the number of metal tracks that are available to route signals through the first region. Signal paths are assigned routes that comprise at least a portion of one or more of the metal tracks. A route from signal paths requiring a repeater to access points to a particular repeater is determined. Thus, the signal paths are assigned to a repeater.

  • Patent number: 5905656
    Abstract: The present invention discloses a system and method for controlling the dispensing of a fine liquid for coating or other applications, by detecting the volume of liquid dispensed when coating a single workpiece and sending a signal to a controller to disable the dispensing when an insufficient volume of liquid is being dispensed. In a preferred embodiment, the fine liquid is spin-on-glass (SOG) used in semiconductor processing machinery during wafer fabrication and the the SOG volume dispensed when coating a semiconductor wafer is measured using a weight measurement instrument, e.g., an electronic scale capable of 0.1 gm. accuracy, which outputs a weight signal that is input, along with a dispenser condition signal from the SOG dispensing machine, to a programmable logic controller (PLC). A set point is selected to produce a desired weight of dispensed liquid, e.g., 1.7 gms. when 2 ccs. are desired, and is programmed into the PLC.

  • Patent number: 5363844
    Abstract: In an NMR system a respiration monitor provides a visual feedback to the patient which enables the patient to perform a series of breath-holds with the patient's diaphragm positioned at the same reference point. This enables NMR data to be acquired over a series of breath-holds without introducing blurring or image artifacts. Between breath-holds a navigator pulse sequence is used to gather NMR data from which diaphragm position is measured, and during each breath-hold the pulse sequence is changed to gather NMR image data.

  • Patent number: 5252951
    Abstract: An advanced user interface for use with a computer system operating on an integrated operating environment. The integrated operating environment allows a plurality of application programs to be running simultaneously, one of which is designated the active application program to which all input data is directed. The advanced user interface allows a user to select among user-friendly input devices to operate any application program according to his individual preferences without change to the application program code. The advanced user interface includes alternate input modules which translate the input signals transmitted from the various input devices into input messages useable by the rest of the interface. The advanced user interface also includes interface profiles which contain mappings of the input messages against corresponding commands useable by the application programs, the integrated operating environment or other modules of the advanced user interface itself.
