Publication number: 20230262334Abstract: 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.

Patent number: 8272114Abstract: 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.Type: GrantFiled: September 3, 2010Date of Patent: September 25, 2012Assignee: Cheng Uei Precision Industry Co., Ltd.Inventors: Yi-chang Yang, Kuo-chuan Chiu, Feng-chi Lee
