Abstract: A switch structure includes a power element, a keypad, a first magnetic component, and a second magnetic component. The second magnetic component is positioned adjacent to the first magnetic component. When the keypad is deactivated, a magnetic attractive force is generated between the first magnetic component and the second magnetic component. When the keypad is activated, the power element controls the first magnetic component to generate a magnetic repulsive force with the second magnetic component.

Abstract: A battery cover assembly for a portable electronic device includes a housing and a battery cover. The housing defines latching holes and a notch. The notch defines a resisting wall. The battery cover includes clasps and a resisting sheet. The resisting sheet includes a resisting portion which has a hooked portion formed thereon and towards the resisting wall. The clasps are latched in the latching holes. The resisting portion is latched in the notch, and the hooked portion resists against the resisting wall.

Abstract: A battery cover assembly for a portable electronic device includes a housing and a battery cover. The housing defines two receiving holes and a groove. The battery cover includes two clasps and a resisting sheet, each clasp including an angled portion and a hooked portion connected to each other, the hooked portion extending downwardly, the resisting sheet having a distal end extending upwardly, the clasps latched in the receiving holes and the resisting sheet latched in the groove.

Abstract: A battery cover assembly is used for a portable electronic device. The battery cover assembly includes a base body, a battery cover, a latching member and an elastic rod. The battery cover forms two hooks. The latching member is slidably attached to the base body. The latching member defines two hook holes. The elastic rod is attached to the base body and provides an elastic force to the latching member.

Abstract: A data storage medium includes a first storage unit and a second storage unit. The first storage unit is used to store a target electronic device ID, the second storage unit stores software installation data. The software installation data includes a copyright protection module, a software installation program, and a software data. When the software installation data is invoked to install the software data, the copyright protection module is invoked and automatically runs. The copyright protection module accesses the first storage unit and reads the target electronic device ID. The software data can be installed in the target electronic device only if the first storage unit contained the target electronic device ID or the first storage unit is writable and the target electronic device ID is stored in the first storage unit successfully.

Abstract: A cover latching mechanism includes a housing and a cover. The housing defines a latching slot. The cover has a latch protruding therefrom and an end portion. The latch defines a guiding surface opposing the end portion, when the end portion tilts relative to the housing, the guiding surface guides the latch to slide out of the latching slot.

Abstract: A portable device comprises a main body, a cover, a pendant mounting structure. The cover is mounted to the main body. The pendant mounting structure is coupled between the main body and the cover, the pendant mounting structure includes a mounting space and a post that engages with the mounting space. When the cover is mounted to the main body, a retaining hole is defined between the mounting space and the post for retaining a hanger element on the device.

Abstract: A battery cover latching mechanism is provided. The battery cover latching mechanism includes a body member, a battery cover and a releasing piece. The body member defines a battery chamber and has an elastic body disposed adjacent to the battery chamber for providing an ejecting elastic force. The battery cover is detachably attached to the body member to cover the battery chamber. The releasing piece is slidably mounted to the body member and elastically resists against the elastic body. As the releasing piece is released, the battery cover is ejected to detach from the body member.

Abstract: A wireless communication apparatus includes a communication module, a display, and a color control module. The communication module is for sending a message to a base station, and receiving a switch command from the base station. The display is for displaying an image. The color control module is for being enabled based on the switch command to replace a background color of the image. A method for replacing a background color of the wireless communication apparatus is also disclosed.
