A smart kettle is disclosed. The smart kettle includes a body that is configured to increase in temperature in response to a magnetic field. The smart kettle further includes a temperature sensor that is located on a bottom of the body and that is configured to measure a temperature of the bottom of the body. The smart kettle further includes a controller that is configured to adjust a strength of the magnetic field based on the temperature measured by the temperature sensor by outputting a control signal.

A convertible table assembly has an item display configuration in which items can be presented for purchasers/guests. The convertible table assembly includes a tabletop assembly and one or more demountable bins for presenting food or other items for purchase, use, and/or consumption by consumers and/or guests. The convertible table assembly also has a table configuration in which the bins are not mounted and one or more power outlets and/or charging and/or communication ports are exposed for connection to electronic devices.

A surface with various layers that provide wireless charging may include at least one of a top surface layer, a second layer, comprising a plurality of lights and a power grid, disposed under the top surface layer, a charging pad disposed on a portion of the power grid, and a third layer, comprising a power supply which provides power to the plurality of lights and the power grid, disposed under the second layer.

Sit-stand desk, such as conversion desks, provide a convenient option for desk work by users who desire the option to selectively sit or stand. Often, the vertical distance between a keyboard and monitor differs when in the sitting configuration versus the standing configuration. A sit-stand desk provided herein allows for a user to transition between a sitting configuration and a standing configuration with a single lifting mechanism with a programmable distance variation between the keyboard and monitor. Accordingly, a user may transition between the sitting configuration and the standing configuration without requiring readjustment of the relative distance between the monitor and keyboard.

A lounge assembly comprising a lower wall structure including at least first and second spaced apart side walls and a rear wall that together form an assembly space, each of the side walls and rear wall including an internal surface, a seat assembly supported between the first and second side walls, a first coupler mounted to the internal surface of the first side wall, a support arm having an arm length dimension between proximal and distal ends, the proximal end mounted to the first coupler adjacent the internal surface of the first side wall for rotation about a first vertical axis and a tablet member supported at the distal end of the support arm for rotation about a second vertical axis through a second range of motion with respect to the support arm.

An article of furniture includes a top member defining a planar work surface. A support structure supports the top member in spaced relationship relative to a floor, the support structure including a plurality of legs. At least one of the legs defines a socket having an opening at a top of at least one of the legs. A power connector is arranged within the socket of at least one of the legs. The power connector is configured to make electrical contact with an electrical connector of an electrical accessory when the electrical connector is received in the socket of at least one of the legs.

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.
