Silent Talker Lie Detector Silent Talker Lie Detector The Silent Talker Psychological Profiler is a camera system which observes and analyses non-verbal behaviour in the form of micro-gestures while a subject is being interviewed, for the claimed purpose of credibility assessment. It is grounded in the psychological theory that non-verbal behaviour is modified by a number of influences when a person is being deceptive. These include arousal (in particular stress), cognitive load, duping delight, and behaviour control. Silent Talker was invented between 2000 and 2002 by a team at Manchester Metropolitan University, Zuhair Bandar, James O'Shea, David McLean and Janet Rothwell. Following its invention,
Detector (radio) to the mixer, the tube or transistor which converts the incoming radio frequency signal to the intermediate frequency. The mixer is called the first detector, while the demodulator that extracts the audio signal from the intermediate frequency is called the second detector. In microwave and millimeter wave technology the terms "detector" and "crystal detector" refer to waveguide or coaxial transmission line components, used for power or SWR measurement, that typically incorporate point contact diodes or surface barrier Schottky diodes. One major technique is known as envelope detection. The simplest form of envelope detector is the diode detector that consists of
