  • Patent number: 5857183
    Abstract: A database co-processor for efficient sequential data retrieval from a relational database is provided which is adapted for connection to a host system via a two-way bus. The database co-processor includes an interface unit connected to receive and transmit data over the two-way bus and a database engine connected to the interface unit by input and output bus means. The database engine includes a relevant field selection unit for storing selection criteria relevant to a database query raised by the processor. A comparator which is incorporated into the database engine compares input candidate data received on the input bus in accordance with the selection criteria and produces a result. The database engine further includes a storage medium for the storage of output candidate data received on the input bus.

  • Patent number: 5821575
    Abstract: A field effect transistor structure having a first type conductivity semiconductor body disposed on an insulator and having formed in different regions of the semiconductor, a source region and a drain region of the opposite type conductivity to the first type, a gate electrode adapted to control a flow of carriers in a channel through the semiconductor body between the source and drain regions, and a Schottky diode contact region between the semiconductor body and one of the source or the drain regions. With such an arrangement, the Schottky diode, when forward biased provides a fixed voltage, about 0.3 volts, between the semiconductor body and one of the source or the drain regions.

  • Patent number: 5797023
    Abstract: An apparatus is described to provide a fault tolerant power-on of a computer system, using a BIOS memory containing a primary power-on system level configuration program for a computer system and a separate memory which contains a subset of the primary power-on system level configuration program. The subset program is accessed automatically, without human intervention, responding to a checksum detector of the BIOS memory data.

  • Patent number: 5401193
    Abstract: Apparatus for patching cables includes a panel 10, FIG. 2 having a patch side for exposing patching connectors, and a punch-down side opposite the patch side for exposing punch-down terminals associated with the connectors. A bracket 12, FIG. 2 supports the panel in a vertical position with the patch side exposed to users. Pivots attach one edge of the panel to the bracket so that the panel can be tilted about the pivot into a position in which the patch side is no longer exposed to users and the punch-down side is exposed to users. There is a supporting surface 40, FIG. 2 for supporting the patch side, when tilted, sufficiently to permit punching down of wires on the punch-down side. The panel may include color coded marking on the patch side for classifying the connector application.
