A pedestal leg assembly includes a pedestal leg and floor base. The leg includes a plurality of teeth near the bottom end of the leg and a connecting bolt in a threaded engagement with the bottom end of the leg. The floor base includes a recessed portion having a slot in its bottom surface to receive the bolt and a release mechanism configured to pivot between a lock position and a release position. In lock position the release mechanism engages at least one of the teeth to prevent rotation of the pedestal leg in one direction. When pivoted into release position, the release mechanism is moved away from engagement with the teeth to allow rotation of the pedestal leg in both clockwise and counterclockwise directions. The pedestal leg assembly may include a powered connection to receive input power at the floor base and transfer the power to a supported table top surface.

An electronic device, a wireless charger and a wireless charging system are disclosed. In an embodiment an electronic device includes a metal housing including electronic components of the electronic device, a recess in the metal housing, a receiver coil configured to receive wireless power, the receiver coil located in the recess outside of the metal housing and a holding structure for the receiver coil, wherein the holding structure comprises a material with a high magnetic permeability, and wherein the receiver coil is electrically connected to the electronic components inside the metal housing.

In an embodiment, a method for providing power to a load using a wireless power receiver includes: wirelessly receiving power using an LC tank; rectifying a voltage of the LC tank using a rectifier; setting a switched-mode power supply coupled between the rectifier and the load in bypass mode; after setting the switched-mode power supply in bypass mode, providing power to the load without switching transistors of the switched-mode power supply; and when wireless power reception is interrupted, providing power to the load by switching one or more transistors of the switched-mode power supply.

In an embodiment, a method includes: wirelessly transmitting power using a transmitter LC tank; wirelessly receiving power from the transmitter LC tank using a receiver LC tank; interrupting wirelessly transmitting power for a slot period; during the slot period, shorting the receiver LC tank; during the slot period and after shorting the receiver LC tank, measuring a transmitter signal associated with the transmitter LC tank; determining a power loss associated with the wirelessly transmitting power based on the measured transmitter signal; and detecting a metallic object based on the determined power loss.

In an embodiment, a method for transmitting data from a wireless power receiver to a wireless power transmitter includes: wirelessly receiving power at a first frequency from a transmitter LC tank using a receiver LC tank; rectifying a voltage of the receiver LC tank using a rectifier; and while wirelessly receiving power, controlling a transistor coupled to the receiver LC tank to cause inflections in a transmitter current flowing through the transmitter LC tank to transmit data, detecting time locations of the inflections of the transmitter current within an oscillating cycle of the transmitter current based on a magnitude of the transmitter current, and determining the data based on the detected time locations.

A shelf unit comprises a shelf and a support shroud. The support shroud defines a shroud concavity extending from the upper wall perimeter edge to the lower wall perimeter edge and bounded by the left and right side edges. The shelf is connected to the support shroud at a position disposed over the upper wall perimeter edge. The shelf optionally has a shelf aperture in communication with the shroud concavity. The shelf unit may be mounted with the shroud covering a wall outlet and an electronic device, disposed on the shelf, has cabling which passes through the shelf aperture and into the shroud concavity. In this application the cabling is contained in the shroud concavity.

A table includes a base defining a wire management pocket and a central area, a power receptacle mounted to the base adjacent the wire management pocket, a leg coupled to the base for supporting the base, and a tabletop supported on the base. The tabletop is slidably removable from the base to provide access to the wire management pocket.

A furniture system includes a first table having a first tabletop and one or more first legs supporting the first tabletop. The first tabletop includes a first upper surface and a first lower surface opposite the first upper surface. The furniture system also includes a second table having a second tabletop and one or more second legs supporting the second tabletop. The second tabletop includes a second upper surface and a second lower surface opposite the second upper surface. A chase is coupled to the first lower surface and the second lower surface to physically connect the first table to the second table. The chase includes a first channel extending therethrough. The first channel is configured to receive one or more cables.

A modular desktop organizer and system including a rectangular base with a tall superstructure and shallow side trays. The superstructure includes a U-slot for holding an upright smartphone with an inductive charger, and a deep cup for holding pens, scissors, and accessories. The base includes a channel-shaped tablet holder at the back. The base is electrically powered and includes USB ports. The modular components have a self-centering bias by way of a bottom bulge with a rounded periphery that nests within the top of another modular component having a complementary rounded lip. The modular components can be stacked to two, three or more levels high in an aligned and neat fashion due to the self-centering bias.

A table includes: a table plate having a penetration hole formed through a portion of an edge thereof; a connector unit coupled to the penetration hole to be disposed at a lower side of the table plate and exposed on an upper surface of the table plate through the penetration hole, the connector unit having a first port; a pair of first table legs disposed at one side of a lower surface of the table plate; a pair of second table legs disposed at the other side of the lower surface of the table plate; and a connection communication unit comprising a second port disposed at one side of the lower surface of the table plate.
