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. The data processing means 21 comprises a preamplifier 22 , an analogue processing circuit 22 and an ADC unit 23 . The data processing means 21 forwards the corresponding data to the data analysis means 25 , arranged to analyze said data in order to yield a condition-related parameter. The determined condition-related parameter is written into a first look-up table 25 a. The data analysis means 25 is further arranged to compare said condition-related parameter to a preset valid parameter stored in a second look-up table 25 b. In case the data analysis means detects that the condition-related parameter exceeds a preset valid parameter, it generates a trigger signal to actuate the indicating means 26 . The indicating means 26 receives the trigger signal and generate a suitable feedback to the passenger, preferably by means of a suitable user-interface 27 . Additionally, the indicating means 26 can be arranged to control a vehicle control system 29 , in order to alter a cabin environment, or to actuate an alarming means of the vehicle, like an acoustic alarm and/or the emergency lights and/or to actuate an engine of the vehicle.

The invention relates to a system ( 1 ) for monitoring a conductivity in a volume. The system according to the invention is suited to be used for industrial and medical applications. The system ( 1 ) comprises a resonant circuit ( 2,4,10 ) comprising a conductive coil ( 4 ) driven by a power supply means ( 8 ), said conductive coil being arranged to induce an oscillating magnetic field in the volume. The power supply means ( 8 ) is arranged to measure a power loss of said resonant circuit due to the conductivity in the volume. The conductive coil ( 4 ) is arranged to be integrated into an insulating fabric ( 9 ). Preferably the conductor forming the conductive coil is interwoven with threads of fabric. For medical applications it is preferable that the system is integrated into a bodywear, for example a T-shirt.

Abstract:
The invention relates to heart measurement and heart monitoring, in particular the measurement of mechanical heart activity, and includes a method and apparatus to using doppler radar to transmit an electromagnetic signal of a certain frequency into, and detect a reflected signal from out of, the chest of the individual, to processing the detected signal to produce an output signal representing the rate of change of the doppler signal associated with the reflected signal and to identify from the output signal a group of at least one characteristic point of the output signal, and further to calculate at least one parameter representative of heart activity, this calculation based on the at least one identified characteristic point. The apparatus provides a system for monitoring which is particularly suitable for use in the home and which does not require repeated use of impedance cardiograms which are inappropriate for use by untrained personnel.

The invention also relates to an optical sensor for a photoplethysmography measurement, comprising a light unit 1 with a light emitter 2 for emitting light into tissue of a patient 8 and/or a light detector 3 for detecting a part of the emitted light after interaction with the tissue, wherein the light unit is embedded in an elastic material 4. The invention further relates to a device for contactless respiration monitoring of a patient 8, comprising: a distance sensor for consecutively detecting the temporal distance variations relative to the patient's chest 12, preferably based on electromagnetic waves; and a calculating unit for determining the breathing activity based on the detected temporal distance variations. The invention is especially useful for providing a reliable and easy to use possibility for simultaneously monitoring respiration action, blood pressure and heart rate with a handheld device which can be used for spot- checking the vital parameters of patients in hospitals.
Abstract:
The invention concerns an apparatus, system, wearable apparatus and concomitant processing system to detect instants in time at which a cyclically pulsating object within the body of an individual is temporarily quiescent, such an object being the heart, an artery or the lungs. The essence of the invention is the use of a doppler radar motion detector, normally used for vehicular speed detection or the detection of building occupancy. The doppler radar motion detector is arranged to transmit electromagnetic signal towards the object and receive reflected electromagnetic signal from the object, and the apparatus is further arranged to identify the instants in time at which the reflected signal indicates the object is temporarily quiescent. The invention is particularly suitable for ambulatory monitoring of the heart.
