A controllable electrical outlet may comprise a resonant loop antenna. The resonant loop antenna may comprise a feed loop electrically coupled to a radio-frequency (RF) communication circuit and a main loop magnetically coupled to the feed loop. The controllable electrical outlet may comprise one or more electrical receptacles configured to receive a plug of a plug-in electrical load and may be configured to control power delivered to the plug-in electrical load in response to an RF signal received via the RF communication circuit. The RF performance of the controllable electrical outlet may be substantially immune to devices plugged into the receptacles (e.g., plugs, power supplies, etc.) due to the operation of the resonant loop antenna. For example, degradation of the RF performance of the controllable electrical outlet may be less when the controllable electrical outlet includes the resonant loop antenna rather than other types of antennas.

A power adapter is disclosed. The power adapter includes housing parts that carries electronic components. To secure the housing parts together, one housing part includes snaps and another housing part includes protrusions and rails. During assembly, the protrusions slide under the snap, causing the snap to deflect in one direction, while the rails slide over the snap, which keeps the snap partially flat but also causes the snap to deflect in another direction. The engagement (during assembly) of the rails and the protrusions to opposing surfaces of the snap cause bi-directional deflection/bending of the snap. When each protrusion is positioned into an opening of the snap, the snap returns to a flat, non-deflected state, and the housing parts are secured together by the snap, protrusions, and rails. The rails support the snaps by limiting or preventing additional deflection of the snap, which subsequently promotes the housing remaining together.

Circuits, apparatus, and methods that provide a connector system that can supply both power and data to a mobile computing or other type of device using a single connection. Further examples also provide a power and data adapter that can provide power and data to a mobile computing device using a single cable. Further examples provide an easy disengagement when a cable connected to the connector is pulled. One such example provides a magnetic connector that uncouples without binding when its cord is pulled. Another example prevents power from being provided at a connector insert until the connector insert is placed in a connector receptacle.

A multiple socket outlet (100) for an electrically adjustable table system is provided with a power supply unit (50) for the provision of a DC supply voltage for the table system from a mains AC voltage. The multiple socket outlet (100) forms an integrated unit together with the power supply unit (50).

A plug-in power supply for supplying a consumer with a low voltage and a plug-in power supply which in operation is configured as a power adapter unit with one of its matching interchangeable mains plug units. The power adapter unit comprises a housing; a voltage transformer module for converting a mains voltage into the required low voltage in the housing; an engaging seat, for the plug unit, at an inner side of the power adapter unit to be directed towards a mains socket, the plug unit being slidably connected with the engaging seat; at least two electric contacts in the seat connecting the transformer module with contacts at an inner side of the plug unit directed towards the power adapter unit; and a locking member, at a rear profile of the engaging seat which limits the sliding of the plug unit. The plug unit comprises at least two mains plug pins, extending from an outer side of the plug unit and connected to the contacts at the inner side of the plug unit; safety recesses, for said contacts at the inner side of the plug unit; and a locking structure, comprising a button, for interacting with the locking member so that pressing on the button releases the structure and allows sliding of the plug unit from the engaging seat.

An electronic device including a PDIC, a charging IC, and a processor. The PDIC determines whether an external device is connected to the USB port, through a first pin of a USB port. The charging IC outputs a first voltage, which is a voltage obtained by boosting a voltage provided by a battery, to the external device through a second pin, when the external device is connected to the USB port. The processor is configured to determine whether the external device connected to the USB port is a first external device having a specified VID and a specified PID, through a third pin of the USB port, and to transmit a first signal, which controls the charging IC to output a second voltage having a magnitude less than the first voltage, to the charging IC when the first external device is connected to the USB port.

Modular system of interfacing consumer electronics devices. The system includes a powered base hub and additional modular components with interface couplers providing electrical continuity between modules. Data transmission between modules may be through the interface couplers or wireless. The system includes a power cord for providing power to the base or wireless pad, but it need not include any additional power or data cords or cables.

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.

A charging device indicating battery percentage, including a power source connector for connecting with a power supply terminal, a charging connector for connecting with a handheld device, a cable connected between the power source connector and the charging connector, a control unit and a display unit, where the control unit is programmed to read a battery percentage of the handheld device from a memory of the handheld device through a signal path of the cable, and drive the display unit to display the battery percentage.
