In accordance with one embodiment of the invention, an electrical adapter system comprises an electrical adapter and an electrical fixture. The electrical adapter provides an electrical connection to an Edison screw socket. The electrical adapter includes an Edison screw base, a voltage converter circuit, and a first electrical connector part.
The Edison screw base is configured to receive a primary voltage from a voltage source. The adapter receives the primary voltage, for example 120 VAC, from an Edison screw light bulb socket and converts the primary voltage using the voltage converter circuit as required to supply a secondary, typically lower, and optionally variable voltage required by the electrical fixture.
Voltage converter circuit is configured to convert the primary voltage to the secondary voltage. The voltage converter circuit may be a switched mode power supply such as a buck converter.
The first electrical connector part is configured to be detachably coupled to a second electrical connector part of an electrical fixture configured to be powered by the secondary voltage. The first electrical connector part and second electrical connector part form a two part correlated magnetic electrical connector connecting the electrical adapter and electrical fixture.
Under one arrangement, the two parts of the correlated magnetic electrical connector to have a fixed position when magnetically aligned. For example, the two parts are fixed (i.e., unable to move) within the electrical adapter and electrical fixtures. In another arrangement, at least one of the two parts of the correlated magnetic electrical connector can move within a bounded area(s) within the electrical adapter and/or the electrical fixture. A moveable part of the correlated magnetic electrical connector may be located to a position and then held in that position by a lock, which may be some mechanical means such as a set screw. Generally, any of various well known mechanical means can to “lock” and “unlock” a connector in accordance with the invention.
In an exemplary embodiment, the electrical adapter comprises a driver circuit and the electrical fixture comprises a light emitting diode (LED) lamp, where the driver circuit can provide a variable secondary voltage enabling control over the LED lamp brightness and power consumption.
In another embodiment, an electrical fixture and/or an electrical adapter (or stackable adapter) may comprise one or more of an audio input device (e.g., a microphone), an audio output device (e.g., a speaker), a video input device (e.g., a movie camera), a video output device (e.g., a display), a radar (e.g., an ultra wideband radar), an environment sensor (e.g., a temperature, moisture, carbon dioxide, radon, smoke, or other sensor), a network communications device (e.g., a communications repeater device, a network router, or a communications portal), a security sensor (e.g., a motion sensor, infrared sensor, optical sensor, or other sensor), a light fixture (e.g., Christmas tree lights), a timer device, a remote control repeater device, or a rechargeable battery (e.g., to enable emergency lighting).
In a further embodiment, an electrical fixture and/or an electrical adapter (or stackable adapter) may function as part of a communication system, a person/object/animal tracking system, a security system, an environment control system, a environment monitoring system, a gaming system, an automation system, or a media (e.g., audio, video) delivery system. For example, an electrical adapter could include Blue Tooth or WiFi communications capabilities.
Under one arrangement, an electrical fixture and/or an electrical adapter (or stackable adapter) comprises at least one of a transponder, a transmitter, a receiver, or an antenna. Under another arrangement, an electrical adapter conveys communications signals via a wiring infrastructure to which an electrical outlet or an electrical fixture having an Edison screw light bulb socket is interfaced or otherwise connected. Under still another arrangement, an electrical adapter conveys tracking signals (e.g., time-domain reflectometry signals) via such a wiring infrastructure.
The magnetic sources employed in the invention may be permanent magnetic sources, electromagnets, electro-permanent magnets, or combinations thereof. Magnetic sources may be discrete magnets or may be printed into magnetizable material.

The coding may cause certain rotational alignments where a repel force is produced. Generally, all sorts of magnetic behaviors can be prescribed using correlated magnetics coding techniques. The coding pattern used in FIG. 5B comprises two concentric circles of maxels oriented in a radial pattern, where the two concentric circles each correspond to six code modulos of a Barker 3 code.
