Abstract: Disclosed are a supplementary bushing, a test probe, and a supplementary testing device. The supplementary bushing has a closed end, an open end, a receiving groove, and at least one first fixing portion. The closed end has a first contact, and the receiving groove is concavely formed from an open end towards the closed end. The first fixing portion is disposed on an inner surface of the receiving groove. The test probe is installed in the receiving hole of a base of the supplementary testing device and has a testing end and a connecting end. The testing end has a second contact, a second fixing portion and a stop portion.

Abstract: A test pin contact buffer, fixed to a test pin base, is a sheet-like structure made of a composite material including a conductive material and an insulating material, and defines at least one contact area corresponding to at least one test pin of the test pin base. The contact area has at least one cutout hole, an insulating deformation structure and a conductive head structure. The insulating deformation structure is extendable and made of the insulating material and extends outward from the conductive head structure. The cutout hole enables the contact area to be in a partial hollow state, which is beneficial for deformation of the insulating deformation structure. The test pin can be used for performing measurement in an indirect manner, reducing the wear of the test pin, prolonging the service life, and improving the measurement speed and efficiency.

Abstract: A high frequency electronic connector is formed by a first connector and a second connector. The first connector has a first body and at least one first terminal, and the first terminal is built in the first body. The second connector has a second body and at least one second terminal, and the second terminal is built in the second body and provided for inserting and connecting the first body. The first terminal has a front end surface in form of a slope or a curved surface, and the second terminal has a front end surface in form of at least one slope or at least one curved surface, so as to increase the contact area between the first and second terminals, and improve the stability of a high frequency signal transmission.

Abstract: Disclosed are a magnetic automobile vehicle device and its multifunctional module. The magnetic automobile vehicle device obtains electric power from a cigarette lighter slot of an automobile vehicle and includes a first magnet and an impact detector. The impact detector generates a distress signal when the automobile vehicle is collided. The multifunctional module includes a second magnet and an output element coupled to the magnetic automobile vehicle device by magnetic attraction and provided for charging or supplying power to the output element, and the output element has an ultrasonic transmitter, a USB slot or an O3 air purifier. Therefore, the device comes with a multifunctional configuration and meets market and consumer requirements.

Abstract: A mouse pad with a touch detection function includes a communication unit, a first ultrasonic unit, a second ultrasonic unit, and a processor including a detection module, a selection module, a calculating module, and a determining module, the detection module detects whether the first ultrasonic unit and second ultrasonic unit receive reflection waves, and determines that an object is touching the mouse pad when the first ultrasonic unit and second ultrasonic unit receive the reflection waves, the selection module selects a predetermined number of first reflection waves and second reflection waves, the calculating module establishes a rectangular coordinates system, and determines coordinate values of the first reflection points and second reflection points, the determining module determines the reflection points having the same coordinate value at a first predetermined interval, selects a reflection point from the determined reflection points as a detection point.
