Patent number: 7327308Abstract: A test device for a frequency modulated continuous wave (FMCW) radar is provided. The test device has a central control unit for monitoring the FMCW radar. When the FMCW radar transmits a frequency modulated continuous signal to search for a target, the central control unit of the test device in present invention will simulate the motion of the target according to a plurality of setting parameters and generate an echo signal to the FMCW radar. The present invention also includes a first digital signal synthesizer and a transmitting unit. The first digital signal synthesizer is coupled to the central control unit for generating and transmitting an intermediate-frequency signal to the transmitting unit according to the settings in the central control unit and a reference clock. The transmitting unit generates the echo signal according to the intermediate-frequency signal.Type: GrantFiled: April 28, 2005Date of Patent: February 5, 2008Assignee: Chung Shan Institute of Science and Technology, Armaments Bureau, M.N.D.Inventors: Shih-Tung Cheng, Yao-Hwa Wen, Ke-Tand Chien

Patent number: 5834643Abstract: The present invention discloses a capacitive-type auto-sensing micro-probe used in high-sensitivity sensor elements. The micro-probe is constructed by semiconductor process technology using solid forming methods to comprise the elements of a probe, a probe cantilever, capacitors, an interface circuit and a signal processing circuit etc. and is fabricated in a micro chip so as to reduce the volume of the system, shorten the distance of signal transmission, and elevate signal sensitivity. By employing capacitive-type sensing principles, the micro-probe establishes capacitive plates on the top of the micro-probe to position at the corresponding capacitive plates located beneath an sensing substrate, and as the probe approaches the sample, the interaction of the sample reacts to the probe to generate deformation signals which, in sequence, are converted into capacitive variation signals. The signals are amplified to derive the surface characteristics of the sample.Type: GrantFiled: October 7, 1996Date of Patent: November 10, 1998Assignee: Industrial Technology Research InstituteInventor: Shih-Tung Cheng
