Patent ID: 7264515

Claim:
Apparatus comprising at least one electrically operated device comprising a jewelry item including a light emitting diode and having a threaded mounting surface and a central contact surface coaxial with the threaded mounting surface, a power supply having first and second output terminals, a display panel, and at least one connector attached to the display panel, wherein each of the at least one connector includes: a housing including a cylindrical mounting surface extending outward around an axis, including threads for engaging the threaded mounting surface of the electrically operated device, wherein the threads of the cylindrical mounting surface are configured to move the electrically operated device along the axis of the cylindrical mounting surface through a first distance with each revolution of the electrically operated device around the axis of the cylindrical mounting surface in engagement with the threads of the cylindrical mounting surface; an electrical contact surface, coaxially disposed with the threaded and electrically conductive cylindrical surface and resiliently mounted to be held outward and to move inward along the axis of the cylindrical mounting surface through an engagement distance exceeding the first distance; a first wire electrically connected to the housing and to the first output terminal of the power supply; and a second wire electrically connected to the electrical contact surface and to the second output terminal of the power supply, and an orientation of each of the at least one electrically operated device is adjusted by rotating the electrically operated device with the threaded mounting surface of the electrically operated device engaged by the threads of the cylindrical mounting surface of the connector and with the central contact surface of the electrically operated device engaging the electrical contact surface of the connector.
