Abstract: A holding apparatus includes a base, a clamp portion protruding from the base, a fixed clamper, and a rotatable damper. The rotatable clamper includes a fixed arm and two resisting arms extending from the fixed arm toward the fixed damper. An adjustment portion includes an angle adjusting member and a locking member. The angle adjusting member includes a base body, a depressible member protruding from the base body, two side arms protruding from opposite ends of the base body, and two resisting portions protruding from the side arms. The two resisting portions resist on the two second resisting arms. The angle adjusting member includes a hook extending from a second bottom of the base body. The locking member includes a main body and at least one locking protrusion protruding from the main body. Each locking protrusion is engagable with the hook to prevent the rotatable clamper from rotating.

Abstract: A device support includes a base, a first supporting frame, and a second supporting frame. One end of the first supporting frame is rotatably connected to the base, and an opposite end of the first supporting frame is rotatably connected to one end of the second supporting frame. A sliding plate is rotatably connected to an opposite end of the second supporting frame, and the sliding plate is slidable on the base, and the sliding plate and the base are magnetically attached to each other.

Abstract: An electronic device includes a shell, a circuit board, a light source mounted on the circuit board, a light guiding member defining a first pattern, a transparent light adjusting member defining a second pattern, a driving member, a sliding member slidably received in the shell, an optical sensor and a processor. The light adjusting member is revolvably mounted to the shell. The sliding member is mechanically coupled to the light adjusting member. The driving member is configured to drive the sliding member to move linearly so as to enable the sliding member to drive the light adjusting member to revolve, thereby rotation of the second pattern relative to the first pattern causing variation of light intensity passing through the light adjusting member. The optical sensor detects the ambient brightness. The process controls the driving member based on the ambient brightness.
