Abstract: Certain embodiments relate to a protective cover with a housing and a latch mechanism. The latch can be hingeably coupled to a back portion of the housing such that the latch is configured to rotate, via the hinge coupling, from a closed position to an open position. The latch can further be slideably coupled to the housing such that the latch is configured to laterally slide out from the back portion of the housing to an extended position, where the bottom side of the latch can be configured to couple to and secure an input device to the surface of the housing.

Abstract: In certain embodiments, a protective cover includes a housing having a surface, and a latch mechanism hingeably coupled to the housing. The latch can include a top side and a bottom side, the bottom side configured to couple to and secure an input device to the surface of the housing. The latch can be configured to rotate, via the hinge coupling, between a first configuration and second configuration. In the first configuration, the top side of the latch can be flush with the surface of the housing and the bottom side embedded within the housing such that the latch does not protrude from the housing. In the second configuration, the latch can be rotated relative to the first configuration and protrude from the housing. The latch can be operable to be rotated open from the first configuration to the second configuration via the hinge coupling.

Abstract: Certain embodiments of the invention include a double hinge for an electronic device case, with hinge stoppers integrally formed to prevent rotation beyond 180 degrees. Certain embodiments include a hinge comprising a first hinge plate, a second hinge plate, and a third hinge plate, where the first hinge plate is adapted to be pivotally engaged with the second hinge plate through the third hinge plate. The first and second hinge plates include two shaft bushings coaxially disposed and facing each other at confronting sides, and the third hinge plate comprises two shaft bushings on two opposite sides so that to coaxially dispose each shaft bushing of the third hinge plate with the shaft bushing respectively of the first and second hinge plate.

Abstract: A laptop stand configured to support a laptop computer on a surface at a plurality of angles includes a platen configured to support the laptop computer. A leg is pivotally coupled to the platen. A support arm is slide coupled to the platen and pivotally coupled to the leg. A latch is coupled to the support arm and is configured to latch and to unlatch from the platen at a plurality of latch points. The latch at the plurality of latch points positions the support arm at a first plurality of angles with respect to the platen and the leg. The latch at the plurality of latch points also positions the platen and the leg at a second plurality of angles with respect to one another. The latch is configured to slide with respect to the platen to move the support arm to rotate the leg with respect to the platen.

Abstract: Aspects of the invention relate to an apparatus including a housing and a slot disposed in the housing, the slot configured to hold an input device in a plurality of upright configurations including at least a forward-facing upright configuration such that the input device faces the front portion of the housing, and at least a backward-facing upright configuration such that the input device faces the back portion of the housing.

Abstract: A method for transmitting data and preventing unauthorized data duplication for human-machine interface device (HID) using Mass Storage Class (MSC) operating on Universal Serial Bus (USB) simulating the HID as an external USB storage device to make data connection to an external computer thus driver installation is not required when the operating system used by the external computer is not compatible with the operating used by the HID. The method encrypted the transmitted data via a dynamic password and does not write the data to the File Allocation Table (FAT) therefore the transmitted data is not under threat of unauthorized data duplication by a third party.
