An exemplary actuating mechanism includes a driving shaft and a driven shaft. The driving shaft includes a connecting end. Engaging blocks are formed on the connecting end with a clearance defined between each two neighboring engaging blocks. The driven shaft includes a pivot end. Protruding blocks are formed on the pivot end with a gap defined between each two neighboring protruding blocks. The driving shaft is connected with the driven shaft via the engaging blocks of the connecting end respectively engaged in the gaps and the protruding blocks of the pivot end respectively engaged in the clearances.

A signal integrity test system and method uses an oscilloscope to test a signal on each test point of a transmission line, obtains test parameter values of the signal on each test point, and compares the test parameter values with preset standard values. If any test parameter value does not match a corresponding preset standard value, a time-domain reflectometer is used to test an impedance value of the test point. If the impedance value matches a standard impedance value of the transmission line, the system and method determines the signal on the test point satisfies integrity requirements.

A clamping apparatus for securing a workpiece is provided. The clamping apparatus includes a fixing base and a first and a second clamping device mounted on opposing sides of the fixing base. The first clamping device includes stacked clamping sheets, each of which is moveable and comprises an inclined clamping edge for contacting the workpiece. A support assembly supports the plurality of stacked clamping sheets; and an operating member is slidable relative to the support assembly and contacting the plurality of staked clamping sheets. The operation member is capable of moving at least one of the plurality of stacked clamping sheets relative to another one when the operation member slides relative to the support assembly, and moving at least one of the inclined clamping edge toward or away from the second clamping device to accommodate workpieces of varying sizes.

In an electronic device and method of protecting software, a software program of the electronic device is invoked. The media access control (MAC) address of the electronic device and a serial number of a hard disk drive that stores the software program in the electronic device are searched. The MAC address and the serial number are compared with MAC addresses and serial numbers included in the software program, to determinate whether it is licensed to run the software program in the electronic device. Usage logs of the software program are further obtained to determine whether running of the software program in the electronic device is expired.

In a method for controlling motion of a mechanical arm, the method moves the mechanical arm horizontally or vertically so that an image capturing device of the mechanism arm focuses on an object. The contours of the object are analyzed, and a central area of the object is established. By making the center of the image area of the image capturing device coincide with the center area of the object at least twice, the method records two positions of the mechanical arm, and calculates a total apparent displacement value of the object and a distance between the object and camera lens of the image capturing device according to the first position, the second position of the mechanical arm and the total apparent displacement value of the object. The method ensures accurate positioning of the mechanical arm.

In a method of compensating the center position of a mechanical arm which has a first probe, a second probe, and a platform, a first test point and a second test point are selected on an electronic product and coordinates of the two points are acquired. A distance R between the first probe and the mechanical arm is received, and an angle θ between the platform and a line formed according to the two points is computed to obtain compensated coordinates of the mechanical arm. The mechanical arm moves to the location of the compensated coordinates, and thus locating the first probe and the second probe respectively at the first test point and the second test point.

An electronic device performs a fire monitoring method in where the electronic device controls a mobile platform to move along a predetermined path, to capture the temperature distribution of an area to be monitored by an infrared capturing device, and detect a consistency of a flammable chemical substance with a smoke detector. The electronic device determines whether the area meets fire conditions by detecting whether the temperature distribution complies with a predetermined temperature distribution, or by detecting whether the consistency is greater than a predefined value. If the area meets the fire conditions, the electronic device determines a fire position, selects one fire extinguisher from the mobile platform to extinguish the fire position.
