    摘要: A system and method for testing objects using a mechanical arm sets one or more first positions. When a user selects one or more second positions of the mechanical arm, a distance between each of the second positions and each of the first positions is calculated. A nearest first position of each of the second positions is determined. Each of the second positions is stored in a test list corresponding to each of the nearest first positions. The mechanical arm is controlled to move to each of the nearest first positions, and tests objects located at the second positions stored in each test list corresponding to each of the nearest first positions.

    摘要: In an electronic device and a method of correcting time-domain reflectometers, two channels of a time-domain reflectometer are connected to a corrector using cables, and the two channels are enabled to transmit pulses. Parameters Step Deskew and Channel Deskew of the two channels are zeroed. Resistance values of the two channels are measured simultaneously, and the value of the parameter Step Deskew of one of the two channels is adjusted according to the Resistance values of the two channels. Times of achieving the same resistance value of the two channels are measured after the cables and the connector have been disconnected, and the value of the parameter Channel Deskew of one of the two channels is adjusted according to the times of achieving the same resistance value. The adjusted values of the parameters Step Deskew and Channel Deskew are displayed through a display unit.

    摘要: A joint mechanism is for a robot. The joint mechanism includes a base; a first drive device mounted on the base including a first drive shaft; a second drive device including a second drive shaft; a joint body defining a plurality of toothed grooves and a guiding groove. A sliding board mounted on first drive shaft, the sliding board slidably located in the guiding groove to guide the joint body to swing relative to the base. A gear mounted on the second drive shaft, the gear meshes with the toothed grooves; a limiting assembly for rotatably mounting the joint body on the base. When the first drive device is started, the first drive shaft is rotated to drive the joint body rotating around the first drive shaft; when the second drive device is started, the second drive shaft is rotated to drive the gear rotating so the joint body swings relative to the base.

    摘要: Parameters of a radio frequency filter can be changed by changing structure of each component of the filter. Material of each component, diameters of each of magnetic cylinders, density of each of conductive coils, thickness of a dielectric layer, and thickness of an insulation tube can be changed. When any component needs to be replaced, each cover is rotated, with connection partitions moving to two slots of an insulation portion, to detach the filter.

    摘要: A method for testing a characteristic impedance of an electronic component includes sending a positioning command to a control computer through a switch, so as to drive a probe holder of a mechanical arm to position probes of a time domain reflectometer (TDR) on a position of the electronic component. The method further receives measured data collected by the TDR, and compares the measured data with preset standard values to determine if the measured data is acceptable.

    摘要: A printed circuit board (PCB) includes two layers, two signal transmission traces, and a vertical interconnect access (via). The signal transmission traces are respectively arranged on the layers. The signal transmission traces are electrically connected to each other through the via. A centerline of the via with a vertical line of the layers form an acute angle θ, the angle θ is less than cos−1[(Lv2−Lt2)/(Lv2+Lt2)]. Wherein Lt is loss of the two signal transmitting traces in a unit length, and Lv is loss of the via in a unit length.

    摘要: A bearing includes a main body, a plurality of first magnetic members, a plurality of second magnetic members, and a plurality of friction members. The main body defines a pivot hole, and a plurality of first receiving portions and a plurality of second receiving portions around the pivot hole. Each of the second receiving portions defines a cutout. The first magnetic members are received in the first receiving portions. The second magnetic members together with the friction members are received in the second receiving portions, thus generating a repelling force between the first magnetic members and the second magnetic members to impel the friction members to partially extend out of the cutouts.
