20150219979 | MICROSCOPIC IMAGE DETECTING INSTRUMENT AND AUTOMATIC FOCUSING METHOD THEREFOR - A microscopic image detecting instrument includes a microscope, a photographing device, a driver, a mark having a predetermined distance from an object, and a controller coupled to the photographing device and the driver. The microscope includes an object stage for holding the object and an objective lens for focusing on and magnifying the object. The photographing device is set above the objective lens to photograph an image presented by the objective lens. The controller controls the driver to move at least one of the object stage and the objective lens to an actual focusing position, according to an actual focal length to the object. The actual focal length to the object is calculated by the controller according to a comparison between an optical definition of a mark image taken as a preliminary target of focus against a predetermined definition calibration curve and the distance between the mark and the object. | 08-06-2015 |

20130312534 | DEVICE AND METHOD FOR TESTING PULLING FORCE - An exemplary embodiment of a testing device for testing a pulling force includes a shell having a test platform, a load sensor mechanism, a control system, a drive and transmission mechanism and a material clamping mechanism. Two portions of a test object are clasped by the load sensor mechanism and the clamp. When the load sensor mechanism is driven to move further away from the clamp via the drive and transmission mechanism, a pulling force perpendicular to the test platform is generated between the two portions of the test object. The load sensor mechanism detects the pulling force and feeds back the detection to the control system. | 11-28-2013 |
