Abstract: An active receiver having a digital-pixel focal plane array (DFPA) ranges a target when observing return pulses from a pulsed laser beam synced with the receiver. The DFPA establishes a time when the pulsed laser beam contacts a target and the range can then be established because the speed at which the laser beam travels is known. Various basis functions may be implemented with the DFPA data to establish when the laser beam contacts the target. Some exemplary basis functions are binary basis functions, and other exemplary basis functions are Fourier basis functions.

Abstract: A method for predicting subject trustworthiness includes using at least one classifier to predict truthfulness of subject responses to prompts during a local or remote interview, based on subject responses and response times, as well as interviewer impressions and response times, and, in embodiments, also biometric measurements of the interviewer. Data from the subject interview is normalized and analyzed relative to an experience database previously created using data obtained from test subjects. Classifier prediction algorithms incorporate assumptions that subject response times are indicators of truthfulness, that subjects will tend to be consistently truthful or deceitful, and that conscious and subconscious impressions of the interviewer are predictive of subject trustworthiness. Data regarding interviewer impressions can be derived from interviewer response times, interviewer questionnaire answers, and/or interviewer biometric data.
