  • Patent number: 6988816
    Abstract: An apparatus and method are provided for providing substantially uniform illumination. The apparatus includes an elongate reflector housing with an inner surface having a substantially constant profile in cross section which is generally concave, an optical center being defined at a geometric focus of the profile of the inner surface. In a preferred embodiment, substantially uniform illumination is achieved by providing an elongate light source positioned within the elongate reflector housing such that a geometric center of the light source is situated preferably spaced outwardly from the optical center of the housing, away from the inner surface of the housing.
    Type: Grant

  • Patent number: 6179654
    Abstract: A cord set including a housing and a coupling mechanism adapted to couple the housing to a structure. The cord set includes a first cord having a first end connectable to a power source and a second end connected to a plug. The cord set also includes a second cord having a first end connectable to the electrical device and a second end connectable to the plug. The housing includes a body defining an axis, an outer surface and a cavity. A first embodiment of the coupling mechanism includes axially spaced ribs extending from an outer surface of the housing body and a snap ring connectable to the structure and the housing. A second embodiment of the coupling mechanism includes a peg protruding from the housing and a lock nut with a detent for coupling the peg to the lock nut. Finally, a third embodiment of the coupling mechanism includes a saddle and cup each having a ridge that cooperates with the axial spaced ribs to couple the housing to the automobile body.

  • Patent number: 6171118
    Abstract: The present invention includes a plug assembly and cord set for use with an automobile accessory that is mounted to an automobile body. The plug assembly includes a plug body having a contact surface, electrical contacts coupled to the plug body and projecting from the contact surface, and a protector cap that accommodates the contacts and protects the contacts from the surrounding environment when the protector cap is in its closed position. The protector cap includes a contact cavity and a cap seal surface surrounding the contact cavity at an open end thereof. The protector cap is coupled to the plug body for pivotal movement between an open position and a closed position wherein the electrical contacts are disposed within the contact cavity and the cap seal surface engages the contact surface to seal the contact cavity when the protector cap is in its closed position.

  • Patent number: 5885098
    Abstract: A cord set for electrically connecting an electrically powered device to a power source. The cord set includes a plug, a receptacle defining an axis and an axial passage extending through the receptacle to accommodate the plug, and coupling means extending axially from the receptacle for coupling the plug to the receptacle. The present invention is also directed to a cord set receptacle that defines an axis and an axial passage extending through the receptacle to accommodate a plug and coupling means extending axially from the receptacle for coupling the plug to the receptacle.
