Abstract: An input module for a torque wrench includes a hollow shank having a first end and a second end. A driving head is partially received in the first end of the hollow shank and has a driving stub laterally disposed thereon. A sensing unit is mounted in the driving head. A grip is disposed on the second end of the hollow shank. An input mechanism includes a display device, multiple rotary rings and a processing unit. The multiple rotary rings are co-axially and rotatably mounted on the outer periphery of the hollow shank adjacent to the grip and electrically connected to the processing unit for inputting an alarm torque value to the processing unit.

Abstract: A binary bidirectional trimming circuit is disclosed. The trimming circuit includes: a first resistor set having 4 resistors in parallel connected and a first fuse bridged two ends thereto provide one trimming step; a second resistor set having 2 resistors in series connected and a second fuse bridged two ends thereto provide eight trimming steps; a third resistor set having 2 resistors in parallel connected and a third fuse bridged two ends thereto provide two trimming steps; a fourth resistor set having 1 resistor and a fourth fuse bridged two ends thereto provide four trimming steps; a first loading resistor; and a second loading resistor. The first resistor set, second resistor set, first loading resistor, third resistor set, the fourth resistor set, and the second loading resistor are in series connected.

Abstract: An active matrix device includes a substrate, scan lines, data lines, pixels, electrostatic discharge ring, a circuit board and a electrostatic protection circuit. The scan lines and data lines are disposed on the substrate, in which the data lines cross the scan lines. The pixels are electrically coupled to the data lines and the scan lines. The electrostatic discharge ring is disposed on the substrate. The electrostatic protection circuit is coupled between the electrostatic discharge ring and the circuit board, in which the electrostatic protection circuit prevents the electrostatic current on the circuit board from entering the substrate.

Abstract: A pin setting circuit and a clock driving circuit are disclosed. The clock pin setting circuit sets the clock pin of the clock driving circuit. The pin setting circuit includes the double one-shot circuit and the switch circuit. The double one-shot circuit includes the first one-shot circuit and the second one-shot circuit. The first one-shot circuit receives a clock signal and generates a first control signal according to the frequency of the clock signal. The second circuit outputs a second control signal according to the first control signal generated. The switch circuit sets the clock pin to the power end or the ground end according to the second control signal.

Abstract: A pedalling vehicle includes a main body, two control handles, two drive links, and a transmission link. The main body includes a front frame a front wheel, a rear frame, two rotation devices, two rear wheels, two cranks, and two connecting members. The rotation devices are connected by the transmission link through connection of the connecting members so that the rotation devices are rotatable synchronously and the rear wheels are movable with the rotation devices synchronously. Thus, the two rear wheels are turned synchronously by connection of the transmission link so as to turn and change the travel direction of the pedalling vehicle exactly.

Abstract: A two dimensional stacking structure for integrated chip stacking on a printed circuit board having a controller electrically coupling on the printed circuit board, comprising a first integrated circuit package, a second integrated circuit package and two interposers. The first integrated circuit package is located beside the controller and electrically coupled on the printed circuit board, and has first leads. The second integrated circuit package is located on the controller, and has second leads. The two interposers having first metal contacts attaching to the corresponding first leads, second metal contacts attaching to the corresponding second leads, and circuit traces extending from the first metal contacts to the corresponding second metal contacts providing electrical communication between the first integrated circuit package and the second integrated package. The two dimensional stacking structure may be applied to a circuit module to decrease the profile of the circuit module.
