Abstract: Examples of back covers for devices are described. In an example, the back cover includes an air-vent, and a region of a surface of the back cover directing air dispensed by a cooling unit of the device toward the air-vent.

Abstract: In an example, an enclosure opener may comprise an external actuator disposed externally to a device enclosure and having a post that extends into the enclosure, and a first separator cam disposed within the enclosure. The first separator cam is be rotatably engaged with the post of the external actuator. Upon rotation of the post relative to the enclosure, the first separator cam is to rotate and engage with an internal surface of the enclosure such that the first separator cam exerts an opening force against the internal surface to cause the device enclosure to separate along a mating seam to open the enclosure.

Abstract: A cover positioning structure of a dual-usage portable computer is disclosed, which comprises a base, at least one slide block sliding on the base, at least one elastic slice imposing a pressure to the at least one slide block, and a rotary member rotated relative to the base. When rotated, a positioning protrusion of the rotary member is correspondingly positioned to a positioning recess of the at least one slide block. Therefore, the structure aforesaid not only achieves the positioning purpose of being damage-free, but also is cost-effective in having a minimum of elements and manufacture processes.

Abstract: A common lock used in a dual-usage portable computer formed of a base member and a display is disclosed to include an elongated operating frame bar longitudinally slidably mounted inside the display of the portable computer, a left-side frame and a right-side frame respectively fixedly mounted inside the display, a left-side hook coupled between the left end of the elongated operating frame bar and the left-side frame for locking the display to the base member when the computer is set in the form of a notebook computer, and a right-side hook coupled between the right end of the of the elongated operating frame bar and the left-side frame for locking the display to the base member when the computer is set in the form of a tablet PC.

Abstract: A common pivot arrangement mounted on a base member with first and second locating holes is disclosed to include a hinge unit having first through holes corresponding to the second locating holes of the base member and second through holes, and a rotary device, which has a mount with through holes corresponding to the first locating holes and a wheel with mounting holes corresponding to the second through holes. For use in a notebook computer, the first through holes of the hinge unit are respectively fastened to the second locating holes of the base member with screws. For use in a tablet PC and the notebook computer, the second through holes of the hinge unit are respectively fastened to the mounting holes of the wheel with screws, and then the through holes of the mount are respectively fastened to the first locating holes of the base member with screws.

Abstract: A dual-action latching device includes two vertical boards, a vertical moving latch, two horizontal poles, a horizontal fixed board, and two springs. Wherein the vertical moving latch of two sides board moves on the two vertical boards, that can impel the top latch or below latch to the cover, respectively, the two springs offer thrust to impel and orient one to slip horizontally and move on two horizontal poles again, and then the groove on imbedding and moving the latch vertically and slippery or putting the groove and orienting it, in order to be able to be used for fastening fixing it in the button trough of the host computer jointly separately.
