Abstract

A computer system processes physiological data signals provided by a physiological-condition monitoring system to determine whether the person may have suddenly experienced fear by comparing the monitored physiological data with stored stress profile data for the person that is based upon measurements of the monitored physiological conditions of the person during situations of stress and/or upon statistical classification in view of a combination of predetermined characteristics of the person. When such processing by the computer system determines that the person may have suddenly experienced fear, the computer system activates an alarm indicator. The computer system includes a neural network for modifying the stored stress profile data in response to an input signal indicating that the computer system provided a false alarm indication. The surrounding conditions that may have caused the determination of probable fear are recorded and transmitted to a remote location.
