  • Patent number: 12225294
    Abstract: An automatic tracking method used in conjunction with a PTZ camera device, wherein an image capturing range of the PTZ camera device is set with a first preset range and a second preset range. The method includes the following steps. Step 1 performs a real-time tracking mode when a target object is within the first preset range, wherein the camera position of a first lens of the PTZ camera device is adjusted with the movement of the target object. Step 2 records an object distance value and perform a region tracking mode when the target object is within the second preset range, which fixes the camera position of the first lens of the PTZ camera device and tracks the target within the second preset range object. Step 3 switches from the region tracking mode to the real-time tracking mode when the object distance of the target object changes.

  • Patent number: 8272114
    Abstract: A connector cover assembling system includes an arrangement apparatus, which aligns covers and includes a transporting channel for transporting the covers to a frame that supports the covers and associated connector bodies. A cover driving member transports the covers one by one from the frame to a separating mechanism, which further transports the cover to a location above a clamping mechanism for being clamped by the clamping mechanism. A lifting mechanism drives an inserting mechanism and the clamping mechanism to the separating mechanism. The clamping mechanism clamps the covers from the separating mechanism. The inserting mechanism drives the clamping mechanism to transport and assemble the cover to the connector body. A holding mechanism holds the connector body during the assembling operation. The control unit coordinates operations of the above-mentioned components. Therefore, manufacturing efficiency of electrical connector can be improved and manufacturing costs reduced.

  • Publication number: 20120024671
    Abstract: A transferring mechanism of contact test, applied to transfer a raw material band of terminals for a contact test of fan-shaped band of terminals is disclosed. The transferring mechanism of contact test comprises a main body, a driving shaft, a driving gear, a driven shaft, a driven gear and a transmission element. The transmission element connects to the driving shaft to rotate the driving shaft, the driving gear. The driving shaft rotates the driven shaft, the driven gear by a belt. The driving gear and the driven gear are ratchets. With the thorn teeth thereof matching with holes of the raw material band of terminals, a transferring mechanism with high speed transfer, exact location and simple structure during the transfer can be realized. Moreover, an arching of the raw material band of terminals can be prevented for guaranteeing the accuracy of the contact test.

  • Patent number: 8033010
    Abstract: A clutching jig used to disassemble a lens socket and a lens component which has a lens base glued on a printed circuit board (PCB) and is fixed in the lens socket by a plurality of buckling pieces of the lens socket abutting on the lens component has a substantially rectangular base. The base defines two opposite first lateral surfaces, a bottom surface, and a slot passing through the first lateral surfaces and the bottom surface to divide the base into a first holding portion and a second holding portion. The bottom surface has a receiving recess communicating with the slot. When the receiving recess receives the lens component, a plurality of resisting slices attached to a periphery of the base inserts into a gap between the lens component and the lens socket for pressing the buckling pieces away from the lens component.
