First Claim
1. A system for monitoring a physiological condition of an individual, comprising:
- a sensor including a signal processing unit and an input arranged to pick up a first signal in a first mode of the system, the first signal being representative of the physiological condition and to forward the first signal to the signal processing unit, a control unit arranged to be positioned remote from the signal processing unit and to be selectively actuated to effect a system mode change, the control unit being arranged to generate a second signal and transmit the second signal to the input of the sensor superimposed on the first signal, the signal processing unit being arranged to decode the second signal and to make the system enter into a second mode upon receipt of the second signal, wherein the input of the sensor is arranged to receive the second signal as a disturbance of the first signal.

Abstract
A system for monitoring a physiological condition of an individual. The system (1) comprises sensing means (3) arranged to pick up a first signal (M) in a first mode of the system, said first signal being representative of the physiological condition and to forward the first signal to a signal processing unit (33). The system comprises an actuatable control unit (2) positioned remote from the signal processing unit, the control unit (2) being suitable to generate a second signal (T) arranged to be superimposed on the first signal (M). The signal processing unit (33, 37) is arranged to decode the second signal and to make the system enter into a second mode upon receipt of the second signal (T).

- 11. A personal monitoring system for selectively actuating a personal monitoring system, the personal monitoring system including an input being arranged to pick up a signal representative of a physiological condition of an individual, the personal monitoring system comprising a control unit arranged to control the personal monitoring system by a generation of a suitable trigger signal which is transmitted to the input of the personal monitoring system, and arranged to superimpose the trigger signal on the signal representative of the monitored physiological condition to control an operating mode of the monitoring system, wherein the control unit is arranged to produce the trigger signal as a disturbance of the signal representative of the monitored physiological condition.

20. A system for monitoring a physiological condition of an individual, comprising:
-
a sensor including a signal processing unit and an input arranged to pick up a first signal in a first mode of the system, the first signal being representative of the physiological condition of the individual, wherein the input of the sensor is arranged to forward the first signal to the signal processing unit; and a control unit arranged to be positioned remote from the signal processing unit and to be selectively actuated to effect a system mode change, the control unit being arranged to generate and transmit a second signal to input of the sensor superimposed on the first signal, the signal processing unit being arranged to decode the second signal and to initiate the system entering into a second mode based upon receipt of the second signal by the sensor, wherein the input of the sensor is arranged to receive the second signal as a disturbance of the first signal.
