Abstract: An example apparatus to retain a computer power brick in a power brick holder includes a plate and a positioning mechanism removably attached at any of a plurality of positions on the plate. The positioning mechanism is attached at a preset position on the plate based on a size of the power brick.

Abstract: An example ventilation system for a computing device includes: a cover slidably engageable with a housing of the computing device to a closed position defining an internal space of the computing device, the cover having first ventilation holes; a system mesh slidably engaged with the cover, the system mesh having second ventilation holes; and a stopper disposed in the internal space of the computing device, the stopper to stop the system mesh at a predefined position when the cover is engaged with the housing in the closed position, wherein the first ventilation holes and the second ventilation holes overlap to define system ventilation holes for the computing device.

Abstract: In an example, a power plug may include a connector to engage with a power receptacle of an electronic device, and a removable lock ring disposed around the connector. The lock ring may include a lock tab disposed on the lock ring and extending in a direction away from a longitudinal axis of the power plug. The lock tab may insert into a lock notch of the power receptacle.

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: A board to board connector includes a first male connector and a second male connector. The first male connector includes a first number of pins. The second male connector is aligned with the first male connector and includes a second number of pins. The first male connector is configured to be removably electrically coupled to a first female connector including a third number of pins equal to the first number and the second male connector is configured to be removably electrically coupled to a second female connector including a fourth number of pins equal to the second number. The first male connector and the second male connector are also configured to be removably electrically coupled to a single third female connector including a fifth number of pins equal to the first number plus the second number.

Abstract: Examples disclosed herein relate to a hinge assembly with a compressible sleeve. In one example, a base member is coupled to an upright member via a hinge assembly. In an example, the hinge assembly include a first securing member, a second securing member including a shaft coupled to the first securing member; a compressible sleeve to engage the shaft, and a spring coupled to the first securing member. In an example, the spring is to engage the compressible sleeve and apply a compressive force on the sleeve in response to a rotational movement of the hinge assembly in a first direction and reduce a compressive force when the hinge assembly is rotated in a second direction.

Abstract: A blotting fillister structure including a first side, a second side and a blotting area is provided. The first side has a first lead-angle surface. The second side opposite to the first side has a second lead-angle surface. The blotting area is located between the first side and the second side. A width of the first lead-angle surface is greater than a width of the second lead-angle surface.

Abstract: A paper feeding method for a printer is provided. The method includes the steps of: feeding a paper for printing a first side of the paper; lifting an up-feeding cap and feeding the paper to a place between the up-feeding cap and a feed roller when the first side of the paper is finished printing; laying down the up-feeding cap after a predetermined duration; and reversing the paper for printing the other side of the paper. The method is suitable for two-side printing and capable of avoiding paper jam or paper damage due to paper distortion by ink.
