Abstract: The invention relates to a system and method for measuring bioelectrical signals of a user. Furthermore the invention relates to a computer program for measuring bioelectrical signals of a user. In order to provide a technique for measuring bioelectrical signals with reduced motion artefacts a new method is provided, comprising the steps of determining the displacement of an electrode, the electrode being adapted for measuring a bioelectrical signal, and adjusting the position of said electrode depending on the determined displacement. The present invention can be used in any system for measuring bioelectrical signals, which uses electrodes, e.g. in any ECG measurement system. With the reduction of artefacts according to the present invention the performance of all those systems can be substantially increased.

Abstract: The invention related to a modulator for a communications system. The modulator comprises a spread spectrum coder, a pulse code modulator having a signal input port connectable to a signal output port of the spread spectrum coder. The modulator performs a robust and error free modulation and coding scheme by using a modified spread spectrum scheme combined with pulse code modulation. The communication system contains a low data rate, noise robust modulation and coding scheme using a very simple transmitter. This results in a very straightforward transmitter circuit, reducing size and costs of the transmitter.

Also, the actuatable emergency response device (14) comprises storage means (11) arranged to store the position information of the emergency response device and the provided position information of the victim.

Abstract: The invention relates to a portable electronic device, like a shaver, a toothbrush, a walkman, a telephony unit, etc., said device being arranged to measure a signal representative of a physiological condition of a user during a conventional usage of said device. In an embodiment of the electric shaver (25), it is provided with a first contact surface (26) comprising a plurality of shaving heads (26a, 26b, 26c). The shaving heads are manufactured from an electrically conducting material, usually a metal and are suited to provide a good electrical contact to the individual's skin during shaving, thus constituting a first electrode. The second contact surface (28?) is provided on the housing of the shaver, in particular on a grip portion (28) thereof, where a contact to a hand of the individual is enabled. The second contact surface (28?) comprises a second electrode (29).

Abstract: The invention relates to a distress signaling system, a body area network for enabling a distress signaling, a method for signaling a condition of a distress and a vehicle arranged with the distress signaling system. The distress signaling system 10 according to the invention comprises monitoring means 11 arranged in a vehicle in order to monitor a vital sign of a seated passenger by means of a sensor 12 arranged to measure a signal representative to said sign. The monitoring means 11 are preferably arranged to perform a continuous monitoring of the vital sign of the passenger and are further arranged to provide a corresponding signal to the front-end electronics 20 of the system 10. The front-end electronics 20 is arranged to analyze the signal from the monitoring means 11. For that purpose the front-end electronics 20 comprises a data processing means 21 arranged to process the measured signal in order to yield data representative to a condition of the passenger.
