  • Patent number: 6771675
    Abstract: Digital signals from a group of three or more circuits (104, 105, 106) are used to create an encoded or combined signal on a common transmission line (108). The encoded signal is then decoded at each different circuit to produce or recreate the digital signal asserted by each different circuit in the group. The encoded signal comprises a signal included in a set of unique signal values, with each signal in the set corresponding to a different combination of digital signals asserted by the group of circuits. Decoding the encoded signal at each circuit (104, 105, 106) in the group involves comparing the encoded signal to a particular reference voltage from a set of reference voltages. A particular reference voltage used in this comparison may be selected using one or more digital signals already decoded from the encoded signal.

  • Patent number: 6683449
    Abstract: An electrically conductive strap is connected to an electrically conductive first connector at one end and connected to an electrically conductive second connector at the other end. Both connectors are mounted on the substrate so that the connected strap extends over a portion of the mechanical component, or otherwise cooperates with the mechanical component, to secure the mechanical component in the desired position. Also, the connection between the strap and the first connector electrically couples the strap to the first connector while the connection between the strap and the second connector electrically couples the strap to the second connector. At least one of the connectors, the first connector for example, is also electrically coupled to a first reference voltage preferably available on the substrate. The electrical condition of the second connector may then be used to indicate whether the strap and therefore the mechanical component is in place on the substrate.

  • Patent number: 6643972
    Abstract: A device for throwing a cast net that facilitates the throwing and improved deployment of said cast net. The device is predominatly disc shaped and contains a multiplicity of radial openings that span an area from near the periphery of said disc to a central portion of the disk. The device is attached to a typical cast net by passing the individual draw strings from the central hub of the net, down through the separate radial openings in the disc shaped device, to the weighted peripheral line of the cast net. The device provides the means for imparting a uniform centrifugal motion to the weighted cord of a typical cast net, then allows the draw strings to freely slide through the device while the net expands. After net deployment, the device then allows the draw strings to move from a point near the circumference of the device to a central portion of the hub of the device upon retrieval.
