Abstract: A flat electronic device includes a main body with a display screen, a support stand, and a rotation mechanism. The support stand is used for supporting the main body. The rotation mechanism pivotally connects the main body and the support stand. The support stand further includes a battery for powering the main body and a connecting portion connecting the battery and the rotation mechanism.

Abstract: A keypad assembly is used for an electronic device. The keypad assembly includes a support member, and a plurality of key strips. The support member defines a plurality of openings and a plurality of cantilever plates, each cantilever plate extending into a corresponding opening. The key strips are received in the openings. Each key strip defines a slot, and each cantilever plate is received in a slot. The cantilever plates provide force to extend one portion of the key strips from the receiving groove.

Abstract: A keypad assembly is used for an electronic device. The keypad assembly includes a support member, a plurality of key strips and a plurality of elastic members. The support member defines a plurality of receiving grooves each with an angled bottom surface. The key strips are received in the receiving grooves. The elastic members are received in the receiving grooves, and each elastic member abuts a corresponding key strip providing a biasing force to extend a portion of the key strips from the receiving groove.

Abstract: A portable electronic device has various functions such as mobile communication, multimedia entertainment, and data processing. The device includes a main body installed with two keyboards and two slide rails, and two sub-bodies respectively equipped with a display. The sub-bodies are pivoted to each other and rotate through a shaft, and slide along slide rails through connecting members on the main body respectively. Therefore, the sub-bodies can be lifted relative to the main body through the shaft and the connecting members, so as to be optionally drawn close to the main body with the two displays facing the same direction, or to stand on the main body with the two displays facing opposite directions. Therefore, two different operating modes are achieved.

The support member defines a plurality of openings and a plurality of cantilever plates, each cantilever plate extending into a corresponding opening. The key strips are received in the openings. Each key strip defines a first slot in which each cantilever plate is received. Each elastic member supports one of the key strips and provides a force extending one portion of the key strips out of its corresponding opening.

Abstract: An electronic device allowing changing of a display background thereof obtains a current location from a navigation device. An image associated with the current location is sought in a memory system, in response to a determination that the current location does not match a location associated with the current display background displayed on a display device. The current display background is replaced with the located image.

Abstract: A portable electronic device and method for constructing a user interface of the portable electronic device are provided. The method predefines function combinations, constructs a coordinate system of a display area on a touch-based screen of the portable electronic device, and generates a matrix user interface based on the coordinate system. The method further divides the matrix user interface into grids, sets a coordinate value for each of the grids, and associates each of the function combinations with one of the grids according to the coordinate value. In addition, the method arranges each of the function combinations to a corresponding grid of the matrix user interface, and displays the matrix user interface on the touch-based screen.

Abstract: An input device for a multiplex control signal is applied to provide one or more input position(s) for a user, where each input position generates a plurality of control signals corresponding to a plurality of input states, and an output control unit determines the output of the control signals from each the same input position according a time parameter.

Abstract: A composite input device and an input method thereof are described. A plurality of pressing members outputs a first signal in response to a press. The first signal is used for actuating a corresponding first function of each of the pressing members. A plurality of optical transceivers is respectively disposed in the pressing members, and each of the optical transceivers transmits an optical signal to pass through each of the pressing members and outputs a second signal on receiving the reflected optical signal. The second signal is used for actuating a corresponding second function of each of the pressing members.

Abstract: A handheld communication device having dual operating modes includes a casing, a display and a keyboard. The casing is formed with an accommodating trough. One side of the accommodating trough is provided with a first connecting port. Further, the casing is provided thereon with a receiver. The display is sealed to cover on the accommodating trough and is displaceable with respect to the casing. The keyboard is detachably received in the accommodating trough. One side of the keyboard is provided with a second connecting port for insertion to correspond to the first connecting port. The keyboard is provided with an emitter for transmitting wireless signals to the receiver and a battery module for providing the necessary power of the emitter. Via the mutual insertion and disconnection between the second connecting port and the first connecting port, wired and wireless operating modes can be switched.

Abstract: A keyboard with five-direction keys is used for a portable electronic apparatus. The keyboard includes a casing with a plurality of openings; and a plurality of keys arranged on the casing in array fashion. Four pattern areas are printed on four diagonal corners of each opening. A legend is printed on each of the pattern areas. The legend is one of letters A to Z, and special symbols such as star key and pound key, and direction signs. Each of the keys is located in one opening, and includes a joystick unit and a keycap arranged on the joystick unit. The keycap comprises a keytop thereon and the keytop is printed with one of numbers 0 to 9. The keyboard generates an electronic signal corresponding to one legend when the keycap is moved laterally in diagonal direction. The keyboard generates an electronic signal corresponding to a number when the keycap is pressed downward.
