Abstract

A physiological-condition monitoring system is attached to a person for providing monitored physiological data signals. A computer system processes the physiological data signals to determine whether the person may have suddenly experienced fear by comparing the monitored physiological data with stored stress profile data for the person. The stress profile data is based upon prior measurements of the monitored physiological conditions of the person during situations of stress. When such processing by the computer system determines that the person may have suddenly experienced fear, the computer system provides an alarm-indication signal to an initial alarm indicator. If the initial alarm indication was false or if the condition causing the person to suddenly experience fear was very brief and no longer poses a threat, the person can operate an alarm deactuation switch to cause the computer system to discontinue the alarm indication signal. 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. Such an input signal is provided when the alarm deactuation switch is operated within a given interval ΔT following commencement of the initial alarm indication signal. The modified stress profile data is stored for comparison with monitored physiological data subsequently received by the computer system. If the alarm deactuation switch is not operated within the given interval ΔT following commencement of the initial alarm indication signal, the computer system provides a second alarm indication signal to an audio alarm indicator and to a remote alarm indicator. The surrounding conditions that may have caused the determination of probable fear are recorded and transmitted to a remote location.
