Problems solved by technology

[0004] A disadvantage of this known system is high power consumption due to the constantly active RF receive channel waiting for a trigger signal from the base unit
This results in frequent battery replacement or recharging, resulting in increased system cost and reduced reliability

Embodiment Construction

[0020] figure 1 An embodiment of a system (1) for monitoring the physiological state of an individual according to the invention is illustrated in a schematic way. The individual is provided with a set of biosensors (3) adapted to monitor the physiological state of the target. Examples of such physiological states are heart rate, body temperature, blood flow, and electroencephalogram, among others. The layout of the set of biosensors (3) is performed according to the target physiological state. figure 1 An example of the layout of the set of biosensors used to monitor cardiac activity is illustrated, in this case the biosensors are placed in the chest area. The function of the set of biosensors (3) is well known to those skilled in the art and will therefore not be explained in detail. For the purpose of permanent monitoring, the set of biosensors (3) must be worn continuously. It is desirable to update the electronic configuration of the set of sensors (3) with some pre-s...

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).

Description

technical field [0001] The invention relates to a system for monitoring the physiological state of an individual comprising sensing means arranged to pick up a first signal in a first mode of the system and to forward said first signal to a signal processing unit, wherein said The first signal represents the physiological state. [0002] The invention also relates to a control unit conceived to be suitable for a personal monitoring system arranged to pick up signals indicative of the physiological state of the individual. Background technique [0003] The system described in the opening paragraph is known from WO 01 / 78831. The known system is arranged to monitor the physiological state of an individual by means of a set of sensors, also referred to as sensing means, located in physical contact with the individual. The sensing device is arranged to pick up signals indicative of the physiological state of the individual. Such signals may be heart rate, respiration rate or o...
