METHOD AND APPARATUS FOR DETECTING AN ABNORMAL SITUATION
First Claim
1. A monitoring system for monitoring an abnormal situation of a target body, the monitoring system comprising:
- a physiological signal monitor configured to monitor a physiological signal;
a processor configured to receive the output signal of the physiological signal monitor and detect an abnormal occurrence of the physiological signal; and
a movement detection sub-system coupled to receive the output signal of the processor and work in a selected detection mode for monitoring the movement of the target body, based on the output signal of the processor, for detecting the abnormal situation.

Abstract
To improve the power efficiency of a monitoring system, especially for worn devices, the present invention provides a monitoring system (300) comprising a physiological signal monitor (310) configured to monitor at least one physiological signal; a processor (320) configured to receive the output signal of the physiological signal monitor and detect an abnormal occurrence of at least one physiological signal; and a movement detection sub-system (330) coupled to receive the output signal of the processor and configured to monitor the movement of a target body, based on the output signal of the processor, for detecting the abnormal situation. The power consumption of the whole system can be decreased by using the monitoring result of physiological signals as a trigger for the movement detection sub-system.
