Experimental study on non-contact detection of breathing and heartbeat based on millimeter wave;

Connecting with Laser technology and modern electronic technology,this paper advances a non-contact detection technology of discontinuous gyration surface's radial jumping error.

Aiming at the difficulty in machining the optic pa rt with aspheric sur face, which is of high hardness/brittleness and is up to the accuracy of submicr ometer or below submicrometer, this paper analyzes the form accuracy and the app lication of the aspheric surface, the relevant fabrication principle and process , as well as the non-contact measurement means.

Combining the linear CCD technology with the practical examples of steel billet detection, the concrete application of the technology in noncontact measurement is further discussed.

A new method was reported for the determination of tanshinol and protocatechuic aldehyde in dripping solution by microfluidic chip with contactless conductivity detection.

A method was established for the determination of pseudoephedrine hydrochloride and dextromethorphan hydrobromide in Bufferin Cold Tablet by micro-fluidic chip with contactless conductivity detection.

How to increase the detection sensitivity on contactless conductivity detection is mail problem.

In consideration of the shortcomings of traditional contact type tubing thread parameter detection method, a non-contact intelligent detection system based on computer visualization technique is designed for tubing thread detection.
