20120205368 | HINGE MECHANISM AND CLAMSHELL DEVICE THEREOF - A hinge mechanism and a clamshell device thereof are disclosed. The clamshell device includes a first cover and a second cover and the first cover can rotate with respect to the second cover via the hinge mechanism. The hinge mechanism includes a main body, an elastic component, and a base. The main body is connected to the first cover and includes a shaft and a projecting part. The elastic component covers the shaft. An internal diameter of the elastic component matches with an outer diameter of the shaft so as to generate a friction force. The first cover can be maintained at any angle by the friction force. The elastic component has a groove used for connecting with the projecting part when the main body rotates to a specific angle. The base is connected to the second cover and has a stop structure used for fixing the elastic component. | 08-16-2012 |
20120306557 | CALIBRATION CIRCUIT AND CALIBRATION METHOD - A calibration circuit and a calibration method are provided. The calibration circuit has a delay circuit, a phase detector, and a controller. The delay circuit delays an input signal to output an output signal, wherein a delay time between the input signal and the output signal is related to an equivalent capacitance and an equivalent resistance of the delay circuit. The phase detector coupled to the delay circuit compares the phases of the input signal and the output signal. The controller coupled to the delay circuit and the phase detector generates a control signal according to the comparison result of the phase detector to adjust the equivalent resistance of the delay circuit. | 12-06-2012 |
20130071176 | QUICK-RELEASE FIXING STRUCTURE FOR ELECTRONIC EQUIPMENTS - In a quick-release fixing structure for an electronic equipment, the electronic equipment includes a plurality of holes and a snap slot, and the quick-release fixing structure includes a substrate, a turning element and a plurality of fixing elements. The substrate includes a plurality of grooves and a port, and each groove includes a first groove hole and a second groove hole interconnected to the first groove hole, and the second groove hole is greater than the first groove hole. The turning element is coupled to the substrate and includes a bump exposed from the port and snapped into the snap slot. Each fixing element is passed through each first groove hole and fixed to each hole. The turning element can be turned to push the electronic equipment to move each fixing element into each second groove hole, and separate the electronic equipment from the substrate. | 03-21-2013 |
20130175264 | Hinge Mechanism and Clamshell Device Thereof - A hinge mechanism and a clamshell device thereof are disclosed. The hinge mechanism includes a base, an axis portion, and a magnetic ring. The base is a metal material and has a pivot portion. The axis portion is pivoted to the pivot portion and can rotate with respect to the base, wherein the axis portion has at least one guiding groove. The magnetic ring is connected to the axis portion and adjacent to the base. The magnetic ring has at least one guiding portion used for sliding along the least one guiding groove. When the axis portion is rotating with respect to the base, the magnetic ring separates from the base and moving along the least one guiding groove by the at least one guiding portion. When the axis portion stops rotating, the magnetic ring attracts to connect to the base by a magnetic force. | 07-11-2013 |
