Abstract: A computer-implemented process for detecting and predicting events occurring to a person, includes: observing, using a sensor, a reading of a parameter of a body part of the person which is one of: horizontal location, vertical height, orientation, velocity, and time of observation, wherein the reading corresponds to less information than needed to define the person's posture; receiving the reading into a computer memory; determining from the received reading a pattern of behavior; detecting a change in behavior; identifying from the change in behavior a combination of one or more readings corresponding to an abnormal event; and producing an alert signal when the combination of one or more readings corresponding to the abnormal event is identified. The process may be practiced using a computing machine including a computer memory; a sensor; and a computer processor.

Abstract: A method in which an electronic device that has one or more movement sensors and a computer processor may detect events in a way that is convenient for daily use by a person. A behavior detection mode may be activated when the electronic device is physically attached to the torso of the person wherein the electronic device may be disposed in a special article (e.g. an article of manufacture, article of clothing, etc.) designed to be attached to the torso of the person so that it activates a behavior detection mode.
