Abstract: A mobile phone (1) includes a main body (3), a keypad (5), and a pair of fasteners (7, 9) slidably and pivotally attaching the keypad to the main body. The main body has a housing (2) with a recess (31) defined in a lower portion thereof. The keypad is received in said recess and comprises a front panel (51) for a keypad input mode and a back panel (53) for a touch screen input mode. A switch between two input modes is achieved by sliding and rotating the keypad around the pair of fasteners to display one side or another side.

Abstract: An antenna module (1) for a mobile phone in accordance with the present invention includes an antenna (2), an elastic element (3) and a feed mechanism (5). The elastic element surrounds a lower part (21) of the antenna and pushes the antenna outwardly. The feed mechanism has a connecting means (50) and a guiding groove (52). The connecting means movably engages with the antenna and slidably engages with the groove. The movement of the antenna between an extended position and a retracted position is regulated by engagement between the connecting means and the groove, and is aided by the resilience of the elastic element. A user can move the antenna between a retracted position and an extended position using one hand.

Abstract: A method to mark an aluminum object (1) includes the steps of: providing an aluminum substrate (10); anodizing and coloring the aluminum substrate; providing a mask (2) with a pattern (25) in the same shape as a mark (15) to be formed on the aluminum object; irradiating a portion of the anodized surface (12) of the aluminum substrate with an ultraviolet beam through the pattern until the desired mark is formed on the anodized surface. The color of the mark is lighter than the anodized surface of the aluminum object, or gradually changes to the color of the anodized surface of the aluminum object.
