  • Patent number: 6813537
    Abstract: In an electrical apparatus wherein electrical devices are interconnected by coupling connectors and a desired interconnection of devices is achieved by an intended interconnection of mating components of coupling connectors, identification elements in one mating component of each connector produce identification signals representing identity of the mating component. Decoding means responsive to the identification signals produce an error signal representing an interconnection of connector components differing from the intended interconnection and, means responsive to the error signal effects a response when the actual interconnection of components differs from the intended interconnection of components. Responses are, advantageously, activation of an error indicator, inhibition of application of power to affected devices, or, with program controlled systems, display of a text error message, facilitation of user intervention for error correction, or automated re-programming to overcome interconnection errors.
    Type: Grant

  • Patent number: 6674006
    Abstract: An assembly for electrical distribution includes not less than six conductors, the assembly defining a distribution portion and a source application portion, load connecting portions of the conductors being arranged in overlying layers in the distribution portion of the assembly. The load connecting portion of each conductor includes at least one load connection portion projecting beyond the overlying layers of the assembly whereby each load is connected between two conductors at the distribution portion of the assembly. The source connection portion of each conductor having at least one connection element, the source connection portion of each conductor being electrically isolated from the source connection portions of all other conductors.

  • Patent number: 4437240
    Abstract: An optically coupled in-process gaging system is disclosed for use with numerically controlled machine tools wherein a battery-powered gage unit is enclosed in a housing adapted for retention in an automatic NC program controlled selection from the NC tool magazine. The gage unit can be placed in a machine tool device, such as a spindle, whose movement is directed by the NC program to place a gage transducer of the gage unit in contact with a workpiece to perform dimensional gaging. The gage unit converts an electrical transducer signal into an infra-red optical FM signal for wireless transmission to a receiver unit coupled to a microcomputer-based control unit.
