Abstract: A mobile navigation device operating in a first mode and a second mode is provided. In the first mode, a satellite positioning module is activated while a dead reckoning module is disabled. A processor calculates the coordinates of the mobile navigation device based on the satellite navigation signals received by the satellite positioning module. In the second mode, the satellite positioning module is disabled while the dead reckoning module is activated, and the processor updates the coordinates based on displacements and rotations detected by the dead reckoning module.

Abstract: A touch panel and an output method therefor are disclosed. The touch panel includes a first substrate, a second substrate, spacers, and a controller set. The first substrate is flexible and has a first electrode layer. The second substrate has a second electrode layer facing the first electrode layer. The spacers are configured between the first and the second substrates. The controller set electrically connects to the first and the second electrode layers to provide a first operation mode and a second operation mode. The controller set can apply a uniform voltage drop electrical field on the first electrode layer or the second electrode layer, so that a resistive touch panel configuration is formed during the first operation mode. The controller set can also apply a uniform electrical field on the first electrode layer, so that a capacitive touch panel configuration is formed during the second operation mode.

Abstract: The present invention relates to a method for selecting characters and a device thereof. The method comprises the steps of sensing a touch on a first key, which has a plurality of characters marked thereon; confirming the touch and displaying the plurality of characters associated with the first key on a display unit; sensing a shifting motion of the touch on the first key; and selecting one of the plurality of characters associated with the first key in response to the shifting motion of the touch. The present invention further provides a character input module and an electronic device for implementing the character selection method.

Abstract: A dual-axis hinge includes at least a connecting section, an upper hinge and a lower hinge. The connecting section has two sides orthogonally connected to the upper and lower hinges respectively. The connecting section has a circuit cavity that communicates with circuit outlets of the upper and lower hinges to form a passage for accommodating a transmission circuit. The upper hinge is connected to a first sleeve for joining the top cover of a folding electronic product, and the lower hinge is connected to a second sleeve for joining the body of the folding electronic product. These connections enable the top cover to rotate in at least two different directions.

Abstract: A multi-configuration portable electronic device including a first body, a second body, a dual-axis hinge and at least a guiding module is provided. The dual-axis hinge has a first axis pivotally coupled to the first body and a second axis pivotally coupled to the second body. The guiding module prevents the first axis and the second axis from acting simultaneously. The guiding module includes a track disposed in the first body and a slide connected with the second body. The slide has an interaction force with the track so that the slide can move from the second body to couple with the track.

Abstract: A dual-axis circuit board is disclosed. The circuit board includes at least an upper circuit board, a lower circuit board, and a connecting circuit board. The upper circuit board connects to the circuit in a top cover of the folding electronic apparatus, and the lower circuit board connects to the circuit in the body of the folding electronic apparatus. The angle between the folding directions of the upper and lower circuit board is approximately 90 degrees.

Abstract: A keyboard with multifunction keys on a panel of a handheld electronic device is provided. The multifunction keys are set in a transverse, tilted or vertical direction and used for typewriting. Each multifunction key has a linear configuration and comprises three symbols such that depressing a central part of the key inputs a first symbol and depressing one end of the key inputs a second symbol while depressing the other end of the key inputs a third symbol. Therefore, the number of keys as well as the total area occupied by the keys on the handheld electronic device can be reduced.

Abstract: A low profile personal computer includes an enclosure having a bottom wall. A riser card including functional circuitry extends vertically from the bottom wall and partitions the enclosure into first and second regions. A motherboard is positioned within the first region of the enclosure along the bottom wall and adjacent to the riser card for interfacing with the riser card. A series of horizontal option card interfaces are located above each other on the riser card within the first region of the enclosure each for interfacing with a corresponding option card and to position the option cards horizontally over the motherboard. The horizontal option card interfaces are capable of interfacing with a maximum of three option cards at the same time. The functional circuitry on the riser card minimizes the number of option cards which enables the overall height of the enclosure to be minimized.
