Abstract: A power and data housing assembly includes a housing body configured to retain and support an electrical device assembly in the form of a radio frequency (RF) transmitter. The RF transmitter is configured to emit a transmitted RF signal that contains one of data transmissions and power transmissions, and acts as a repeater and/or range-extender or signal redirector for directing wireless power and/or data signals into regions of work areas that otherwise would receive only marginal signals, or none at all.

Abstract: A wireless electrical power transmission system includes a panel having a recessed area for receiving a wireless power transmitter, such as an electric field resonant transmitter. The panel has a first outer surface and a second outer surface opposite the first outer surface, with a thickness defined between the first and second outer surfaces. The recessed area is formed in the first outer surface, and the recessed area has a depth that is less than the thickness of the panel. Electrical wiring is coupled to the wireless power transmitter and passes through an opening formed in the panel, which opening is accessible from the recessed area, and the electrical wiring is in communication with an electrical power source.

Abstract: An electrical power unit is positionable in or along a work surface and includes a housing with a movable cover that is positionable in open and closed positions at an upper region of the housing. The cover defines an interior region in which a wireless power transmitter is mounted. A lamp unit is disposed in the housing or the cover. The lamp unit is configured so that emitted light is visible from outside the power unit when the cover is closed. The wireless power transmitter is operable to selectively illuminate the lamp unit when the wireless power transmitter is energized. Optionally, at least one direct-contact electrical or data receptacle is provided at the housing, and may be arranged or positioned so that it is accessible at least when the cover is in the open position.

Abstract: A visual indicator system including a communications module, a processor, and a visual indicator. The communications module is able to wirelessly receive a condition report from a wirelessly connected device. The processor is able to select a status in response to the condition report received by the communications module. The visual indicator is able to visually indicate a status based upon a selected visual configuration of the visual indicator. The processor is also able to select a particular configuration for the visual indicator based upon the selected status.

Abstract: A data-secure electrical connector is operable to provide electrical power to a portable electronic device via a connector that is capable of transmitting electrical power and electronic data to the device, but without establishing an electronic data connection with the device, while providing an indicia to a user when the data-secure electrical power connection has been made.

Abstract: A twist-lock electrical connector includes first and second connector portions each having a respective interface end portion and longitudinal axes. The first connector has a projection and the second connector has a corresponding bore along the connectors' respective longitudinal axes. Two electrical contacts are located at opposite sides of the projection at the first interface end portion, and two other electrical contacts are located at opposite sides of the bore at the second interface end portion. The interface end portions are configured to engage one another at a first rotational orientation in which the bore receives the projection when the first and second longitudinal axes are made substantially coaxial and the connector portions are brought together along their axes. The interface end portions further engage one another at a second rotational orientation in which the first pair of electrical contacts electrically engage the second pair of electrical contacts.

Abstract: An electrical power coupler is configured to convey electrical power upon detecting that a compatible other coupler is properly aligned and no undesirable operating conditions are detected. The power coupler includes a first ferromagnetic metal adjacent a first magnet, a hall sensor for detecting a magnetic field in the first ferromagnetic metal, and at least two first electrical contacts. A control unit is in electrical communication with the power conductors, and includes an electrical switch operable to selectively allow a flow of electricity from a power source through the associated power conductors when the hall sensor detects the magnetic field, such as when the first electrical contacts are in contact with at least two second electrical contacts of another electrical power coupler. The second electrical contacts make contact with the first electrical contacts upon proper alignment of a correspondingly configured other electrical power coupler.

Abstract: An electrical power coupling includes a pair of power coupling parts, each having a base and a coupling portion that is movable relative to said base. Each coupling portion has first and second electrical contacts that are spaced laterally outboard, by respective first and second distances, from centers of the coupling portions. Magnetic elements attract the respective coupling portions to one another when the coupling portions are positioned closely to one another. Each coupling portion moves relative to its respective base to align the coupling portions with one another and establish electrical connections between the first electrical contacts and between the second electrical contacts. Optionally, at least two electrical contacts are arcuate or circular in shape.
