Abstract:
An input module of a mobile communication device includes an interlinking unit, an input unit, and a pressing unit. The interlinking unit has a protrusion and a first sliding member. The input unit has a second sliding member opposite to the first sliding member. The pressing unit has a groove, a guiding member, and an elastic member. The groove and the interlinking unit move together. One end of the guiding member moves between a first position and a second position in the groove. The elastic member provides a resilience force for the groove. When an external force is applied to the protrusion of the interlinking unit, the interlinking unit drives the groove in a first direction to allow the guiding member to relatively move from the first position to the second position or from the second position to the first position. A mobile communication device is also provided.
Abstract:
An electronic system and a cell module thereof are provided. The electronic system includes an electronic device and a cell module. The cell module includes a cell, a discharge switching circuit, and a surge current suppressed and controlled circuit. The discharge switching circuit is coupled to the cell. The surge current suppressed and controlled circuit is used for controlling the discharge switching circuit, so that the current flowing from the cell into the electronic device gradually increases by the discharge switching circuit when the electronic device is coupled to the discharge switching circuit.
Abstract:
A portable electronic device includes a first body, a second body, a guiding assembly, a first elastic element and a connecting part. The first body has a track portion and a protrudent block, and the second body has a fastening part. The guiding assembly has a sliding rod and a guiding part. The two ends of the sliding rod are fixed at the first body, and the sliding rod passes through the guiding part. The first elastic element connects to the first body and the second body. The connecting part is fixed at the second body. The sliding portion is slidingly disposed at the track portion, and the pivot passes through the guiding part. As a result, not only the first body slide relatively to the second body, but also an angle is formed between the first body and the second body.
Abstract:
A casing of a mobile communication device includes a casing body, a cover and a screwing assembly. The outside of the casing body has a battery holding recess and a screw hole. The cover can cover the battery holding recess. The screwing assembly is fixed to the cover. The screwing assembly is screwed in the screw hole to fix the cover to the casing body or partially screwed out of the screw hole to rotate and raise the cover from the casing body. A mobile communication device is also disclosed.
Abstract:
A method for dynamically adjusting the brightness of an image is provided. In the method, a plurality of first pixel values of pixels in a captured display image are converted to a plurality of first brightness values when an application program is executed with a full screen picture. Then, the size and the distribution of the first brightness values are adjusted to obtain a plurality of second brightness values. Afterward, the second brightness values are converted to a plurality of second pixel values with which the pixels of the display image and displayed on the screen are overwritten. Therefore, the brightness of each display image can be dynamically adjusted, which is convenient.

Abstract:
An electronic device has a first circuit board, a first fan, a second circuit board, a first heat sink, and a first air ventilation duct. The first fan and the first circuit board are electrically connected together. The second circuit board is electrically connected to the first circuit board; the first heat sink is electrically connected to the second circuit board; and the first air ventilation duct is connected to the first fan and the first heat sink. The first heat sink introduce the heat generated by the electronic element on the second circuit board to the first fan for better cooling performance. Therefore, the present invention requires only the first fan and the second fan, but is able to provide high cooling efficiencies with a low noise signature.
Abstract:
A portable electronic system including a body and a dock is described. The body has a waterproof first connector and a first attracting portion, wherein the first connector has a plurality of electrical terminals. The dock has a second connector and a second attracting portion, wherein the second connector has a plurality of retractable pogo pins. When the body is placed on the dock to make the first connector connected to the second connector, the magnetic force between the second attracting portion and the first attracting portion makes the electrical terminals compress the retractable pogo pins to a critical distance to achieve the electrical connection between the body and the dock.
