A power adapter is provided for a computer including a power port and a housing defining an aperture. The power adapter includes a power head, a lock head disposed on the power head and a main housing including a body affixed to a security element, wiring for supplying power to the computer extending through the body to the power head and a lock system selectively actuatable with a key to orient the lock head in first and second orientations. The first orientation is characterized in that the power head is movable relative to the aperture for power head insertion into and removal from the power port. The second orientation is characterized in that the power head is immovable relative to the aperture.

Computing devices, input devices, keyboard assemblies, and related systems include a set of conductive traces or leads configured to transfer a capacitive load from an appendage of a user or another capacitive load source from a remote location, such as on a keycap of the keyboard, to a conductive portion or electrode on the keyboard that is positioned near a touch-sensitive interface of a computing device. The capacitive load is thereby transferable through the conductive traces or leads to the touch-sensitive interface without having to directly apply the load, such as by touching a finger to the interface. This can reduce or eliminate the need for on-screen controls or keyboard interface elements in a touch screen device without having to use a more expensive and energy-draining wired or wireless connection between the computing device and a keyboard case or accessory for the computing device.

Provided are a set and a display device. The set includes a display module including a display panel, a module mold frame, a front housing and a backplane. At least part of front housing is located on a light-emitting side of display panel and is disposed opposite to at least one side edge of module mold frame; front housing is provided with first and second connecting structures, the module mold frame has a first module mold frame side edge where a third connecting structure is disposed, the backplane of display module is provided with a fourth connecting structure. First and third connecting structures cooperate to limit the position of front housing in a plane parallel to a light-emitting surface of display module; second and fourth connecting structures cooperate to limit the position of front housing in a direction perpendicular to light-emitting surface.

A method is provided for locking and unlocking an electronic power tool. The method includes receiving, at a locking device, information associated with the electronic power tool, and generating, at the locking device, a lock code based on the received information. The method further includes transmitting, by the locking device, the lock code to the electronic power tool. The lock code is configured to lock the electronic power tool upon being received at the electronic power tool.
