    Abstract: In one example, a computing device may include a circuit board having a contact pad disposed at an edge of the circuit board, and a chassis in which the circuit board is installed. The chassis may include a circuit board holder to engage the edge of the circuit board to retain the circuit board in a defined position relative to the chassis. The circuit board holder may be grounded. Further, the computing device may include a controller to receive a signal from the contact pad, the signal indicative of a presence of the circuit board holder contacting the contact pad. Furthermore, the controller may detect a form factor type of the chassis based on the received signal.

    Abstract: An electronic device includes a body and an image capturing assembly mounted on the body. The image capturing assembly comprising an imaging device and a device control assembly coupled to the imaging device to control a movement of the imaging device along a central axis of the image capturing assembly to allow the imaging device to be positioned at multiple positions along the central axis of the image capturing assembly. The device control assembly includes a first guide member, a second guide member rotatably disposed within the first guide member, and an inner body movably disposed within the second guide member. In response to a rotational motion of the second guide member with respect to the first guide member, the inner body is to move in axial direction with respect to the second guide member to move the imaging device along the central axis of the image capturing assembly.

    Abstract: An example device includes a wireless charging circuit to wirelessly charge a portable electronic device. The device further includes a first photosensor positioned within an effective charging range of the wireless charging circuit, the first photosensor to output a first signal, and a second photosensor positioned outside the effective charging range, the second photosensor to output a second signal. The device further includes a control circuit connected to the wireless charging circuit, the first photosensor, and the second photosensor. The control circuit detects the portable electronic device positioned within the effective charging range of the wireless charging circuit by detecting a difference between the first signal and the second signal. The control circuit turns on the wireless charging circuit in response to detecting the difference. The control circuit turns off the wireless charging circuit in response to detecting that the first signal matches the second signal.
