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,
Radar detector detector Radar detector detector A radar detector detector (RDD) is a device used by police or law enforcement in areas where radar detectors are declared illegal. Radar detectors are built around a superheterodyne receiver, which has a local oscillator that radiates slightly. It is therefore possible to build a radar-detector detector, which detects such emissions (usually the frequency of the radar type being detected, plus about 10 MHz for the intermediate frequency). Some radar guns are equipped with such a device. However, like any device that detects stray emissions from electronic equipment, it is easily defeated by using adequate shielding. The
