Silent Talker Lie Detector the Silent Talker Adaptive Psychological Profiling architecture and its specific instantiation as a lie detector, were patented internationally. In the interim, the inventors have been involved in raising investment funding and the code has been ported to various programming languages and speeded up from near real-time to real-time response. Current research includes adapting the technology to the measurement of comprehension amongst participants giving informed consent to take part in clinical trials Silent Talker Limited was incorporated on 9 April 2015 to commercialize this technology worldwide. The subject of the interview is observed by one or more cameras (e.g. head-and-shoulders, full
Ratio detector Ratio detector The ratio detector is a type of detector circuit, commonly used in radio receivers for demodulatng frequency modulated (FM) signal. The ratio detector is a variant of the Foster-Seeley discriminator, but one diode conducts in an opposite direction, and using a tertiary winding in the preceding transformer. The output in this case is taken between the sum of the diode voltages and the center tap. The output across the diodes is connected to a large value capacitor, which eliminates AM noise in the ratio detector output. The ratio detector has the advantage over the Foster-Seeley discriminator that it
