Abstract: An electrical power and/or electronic data unit is mountable in a floor, and is fitted with an upper bezel that is openable and closable to provide selective access to an interior of the unit, which is optionally fitted with one or more electrical power or data outlets. A lower insert including an intumescent block is supported below an upper housing, and is angularly adjustable relative to the upper housing. One or more bores or openings formed in the lower insert allow the passage of cords into a pass-through opening in the upper housing, and out through an upper bezel cover.

Abstract: An electrical power and/or electronic data unit is mountable in a floor, and is fitted with an upper bezel that is openable and closable to provide selective access to one or more electrical power or data outlets. A bezel supports one or more shutters that are movable between open and closed positions. Optionally, the shutters are supported on an openable main door that provides additional access to the outlets when the main door is open. The main door can be closed and opened with the shutters in either the open or closed positions. Respective top surfaces of the shutters, the main door, and the bezel may be co-planar when the main door and shutters are closed, and the shutters may be hidden entirely beneath the main door when the main door is closed and the shutters are open.

Abstract: An electrical power or electronic data unit includes an outer housing and an inner housing that is insertable into the outer housing. The outer housing has an outer front face panel defining an outer receptacle opening and the inner housing has an inner rear housing portion plus an inner front face portion defining an inner receptacle opening aligned with the outer receptacle opening. A circuit board substrate is positioned inside the inner housing with an electrical contact mounted to the board substrate and aligned with and accessible through the inner and outer receptacle openings. A contact support extends rearwardly from the inner front face portion adjacent the inner receptacle opening, the contact support serving to limit movement of the electrical contact during insertion of a plug or prong into engagement with the electrical contact.

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 at a work surface and includes an upper housing including an upper surface and a lower surface spaced below the upper surface to define an upper housing chamber. A wireless power transmitter is disposed in the upper housing chamber and is operable to convey electrical energy to a wireless power receiver positioned at or above the upper surface. A base is coupled to the upper housing and extends downwardly therefrom, the base being configured for insertion into an opening formed in the work surface or into a space defined between two adjacent work surfaces. The base is further configured to facilitate securing the electrical power unit to the work surface or the adjacent work surfaces.

Abstract: An electrical power cord includes intelligent switching capability. An electrical power input receives electrical power from a power source, and selectively conveys that power to an electrical power output only when certain occupancy or power usage criteria are met. The electrical power output conveys electrical power to an electrical consumer when a switch disposed along the power cord is closed. The switch is actuated in response to a signal received from a sensor, such as an occupancy sensor or a power consumption sensor, and breaks continuity along the power cord when signals received from the sensor indicate that the occupancy or power usage criteria are not being met, which criteria may be customized for a particular application. The electrical power cord is operable to automatically reduce or substantially eliminate power consumption at its power output end.

Abstract: An electrical system for group seating arrangements includes a plurality of conduit assemblies and a plurality of branch assemblies, each made up of hollow casings with electrical connectors and seals at their opposite ends, and with electrical conductors providing continuity to the electrical connectors of each branch and conduit assembly. A mechanical latch or lock coupling at each of the ends, combined with a seal at each coupling or junction, provides a secure and contaminant-resistant mechanical connection and at each conduit-to-conduit or conduit-to-branch junction. The hollow casings of the conduit assemblies and branch assemblies may be made of high-strength material so as to resist damage from impacts when installed in high traffic areas such as stadiums, arenas, theaters, and public transit vehicles.

Abstract: An electrical power and data system for group seating arrangements includes a DC power supply for converting an AC voltage input to a DC low voltage output, a low voltage main line and at least one branch line with a power output in communication with the DC output, and an occupancy sensor at a seating area for generating an occupancy signal. The power output of the branch line positionable at the seating area, and configured to supply power to a portable electronic communications device. A switch energizes and de-energizes the electrical power output in response to the occupancy signal, and the branch line, main line, and DC power supply cooperate to provide electronic communications between the portable electronic device and the electronic data network when the DC power supply is energized.
