  • Patent number: 11970111
    Abstract: A vehicular exterior rearview mirror assembly includes a mounting arm and a mirror head at one end of the mounting arm distal from an attachment portion of the mounting arm that is configured for attachment at a vehicle. A mirror reflective element is fixedly attached at the mirror head. An innermost side of the mirror reflective element is attached at a front side of an attachment plate. The mirror reflective element moves in tandem with movement of the mirror head relative to the mounting arm when the driver of the vehicle operates an electrically-operable actuator. The attachment plate includes wall structure that extends from the front side of the attachment plate and circumscribes and spans the perimeter circumferential edge of the glass substrate and does not encroach onto and does not overlap the front surface of the glass substrate of the exterior mirror reflective element.

  • Patent number: 11970113
    Abstract: A vehicular vision system includes a forward-viewing camera located behind and viewing through a vehicle windshield, a rearward-viewing camera located at a rear of the vehicle, and a common image processor operable for processing captured image data. A video display screen is located within the interior cabin of the vehicle viewable by a driver of the vehicle. The common image processor processes first image data captured by the forward-viewing camera to detect at least one vehicle present exterior the equipped vehicle. Responsive to the vehicle being shifted into a reverse gear and while the driver is executing a reversing maneuver, video images derived from image data captured by at least the rearward-viewing camera are displayed by the video display screen.

  • Patent number: 7674680
    Abstract: The invention is directed to a device for regulating the flow of electric current with high dielectric constant gate insulating layer and a source and/or drain forming a Schottky contact or Schottky-like region with a substrate and its fabrication method. In one aspect, the gate insulating layer has a dielectric constant greater than the dielectric constant of silicon. In another aspect, the current regulating device may be a MOSFET device, optionally a planar P-type or N-type MOSFET, having any orientation. In another aspect, the source and/or drain may consist partially or fully of a silicide.

  • Patent number: 6081875
    Abstract: A backup system and method provides for creation of a reconciled snapshot backup image of a database while the database, residing on a disk array system, is in use by users. A backup computer running a commercial backup utility is connected between the array system and a tape storage system. While the backup is underway, write requests to the database are suspended until the data currently in those data blocks is copied and stored in an original data cache. The disk system address of the copied block and a pointer to the location of the block in the cache are stored in a map. The backup utility incrementally reads portions of the database from the disk system and forwards those portions to the tape system. Prior to each portion being forwarded to the tape system, all data blocks in the portion which have an address that corresponds to the address of a block in the cache are discarded and replaced with the data from the cache for that address.

  • Patent number: 5677677
    Abstract: The difference between the temperature of a heat exchange medium leaving the evaporator unit of a chiller and the temperature of the refrigerant in the evaporator unit is monitored relative to a real time alarm limit for this temperature difference. The real time alarm limit is computed from time to time by a microprocessor. The value of the computed alarm limit will vary with the cooling load being experienced by the chiller's evaporator unit.

  • Patent number: 5546073
    Abstract: The electrical current drawn by a drive motor for the compressor unit of a chiller is monitored relative to a real time alarm limit for this electrical current. The real time alarm limit is computed from time to time by a microprocessor. The value of the computed alarm limit will vary with the cooling load being experienced by the chiller's evaporator unit.

  • Patent number: 5539382
    Abstract: The difference between the temperature of refrigerant leaving the condenser unit of a chiller and the temperature of water leaving the same condenser unit is monitored relative to a real time alarm limit for this temperature difference. The real time alarm limit is computed from time to time by a microprocessor. The value of the computed alarm limit will vary with the cooling load being experienced by the chiller's evaporator unit.

  • Patent number: 5539385
    Abstract: Refrigerant pressure in the condenser unit of a chiller is monitored relative to a real time alarm limit for the refrigerant pressure. The real time alarm limit is computed from time to time by a microprocessor. The value of the computed alarm limit will vary with the cooling load being experienced by the chiller's evaporator unit.

  • Patent number: 4453963
    Abstract: A method and apparatus for controlling the delivery of gobs to each section of a multiple section glassware forming machine to assure that no one section can authorize the delivery of a gob of molten glass to any other section. The invention discloses means for monitoring the time of occurrence within a machine cycle of the delivery enable pulse from each section and for determining whether this delivery enable pulse occurs within a predetermined time window. In the event either the leading or trailing edge of this pulse occur outside predetermined time windows, the gob interceptor associated with the machine is activated to reject the gobs intended for that section. The invention also discloses means for monitoring the motion of a gob interceptor to provide assurance to an operator that the interceptor has moved to either a delivery or intercept position in a timely manner.
