There show positive results on the method and acquisition system collects infrared signals after testing,it also proves this test method has critical practical value.

The infrared signal examination switch is designed to achieve when the human body close to infrared signal detectors,the load is opened automatically according to signal processing results,if the human does not leave also is moving,the load works continually,after until the human leaves the time delay and closes the load.

In order to achieve viewable analysis and research of infrared signal, taking advantage of serial communication of singlechip and computer and the virtual screen of VB,this system can identify automatically infrared signal and display real time infrared wave on the machine PC.

Study on the termination decision based on emerging technology firm's signal learning

This paper induces and analyses the information during the venture project development process firstly;then chooses the good(bad) signal observed by venture capitalist as the binary learning signal and proposes signal learning model from the perspective of Bayesian posterior estimate considering three conditions that the good(bad) signal observed along with project development.

The radiation temperature and control precision of its infrared signal source are estimated.
