Abstract: In one embodiment of the present invention, a method for determining if a subject is snoring is disclosed, including the steps of: determining if the subject is present in a bed; determining if there is snoring; determining if snoring is emitted from the subject; and generating an output signal, wherein the output signal is dependent on if the snoring is emitted from the subject. A computer program arranged to cause a computer to perform the steps of the method is also disclosed.

Abstract: A system and method for registering the temperature of a person, wherein a textile product, intended to abut against the person during use, is provided with a number of temperature sensors and a registration unit for registering measurement values from the sensors. The system may be used for monitoring the state of a person, wherein a predetermined threshold condition is monitored, and an alarm signal is emitted to activate an alarm unit when the condition is fulfilled. The system may also be used for controlling physical characteristics of a foundation, such as temperature and/or hardness, based on the state of a person being present thereon.

Abstract: A system and a method are proposed for controlling at least one physical property of a bed based on the state of a person staying in the bed. A lying part in the bed is provided with a plurality of sensors adapted to continuously measure physical magnitudes as a measurement of the person's state. Measured values from the sensors are received, processed and analysed by a registration unit, for controlling physical properties of the bed.

Abstract: In a method and a system the autonomic nervous system, and in particular parameters reflecting the current condition of the autonomic nervous system, are monitored for detecting a lower level of wakefulness. One such parameter, which has been found to indicate such a state, is cardiac oscillation. Thus, the autonomic nervous system affect the heartbeat of a person falling to sleep in such a way that the heartbeat will go through a series of acceleration and de-acceleration.

Abstract: For estimating a person's age and for providing an emergency alarm function, a stationary pressure sensitive means (2, 3, 4) contacts part of that person's (1) body, and generates a signal in correspondence to that person's body movements relative to said means. A detector/filter circuit (5) connected to said means, separates signals corresponding to true body movements, heartbeat-related body movements, and respiration-related body movements. Calculation and comparison circuits (6, 9; 7, 10; 8, 11) are adapted to receive these signals and compare them with previously received signals to determine possible changes. A correlator (12) correlates the output signals from the calculation and comparison circuits to produce a resulting change signal which is compared with a preset threshold in a threshold detector circuit (13). The output signals can be used for activating/inactivating an air-bag system or for triggering an emergency alarm via a mobile telephone and a GPS system.

Abstract: In a medical meassuremnet system, measurements can be carried out at a distance from a hospital. Thus the patient is connected to a measuring system comprising measuring sensors and a unit for collecting data comprising a transmitter. The system also comprises a centrally located surveillance unit. The measuring sensors sense various physical and physiological parameters, for example brain activities, actions of the heart, respiration, blood pressure, blood values/tests and body movements. The sensed signals are transmitted to a portable small device of low weight for collecting and/or analyzing data, which is connected to a central surveillance unit, for example via the public switched telephone network (PSTN), a radio system, in particular a cellular radio system, or via a satellite communication. In a preferred embodiment the measuring sensors comprise a preamplifier having an identification circuit. The identification circuit is used for providing each preamplifier with a unique identity.

Abstract: For monitoring and estimating a person's wakefulness, a stationary pressure sensor contacts part of that person's body and generates a signal corresponding to that person's body movements relative to the sensor. A detector/filter circuit connected to the sensor separates signals corresponding to true body movements, heartbeat-related body movements, and respiration-related body movements. Calculation and comparison circuits are adapted to receive these signals and compare them with previously received signals to determine possible changes. A correlator correlates the output signals from the calculation and comparison circuits to produce a resulting change signal which is compared with a preset wakefulness threshold in a threshold detector circuit. An alarm device is triggered, when the preset threshold is reached as an indication of a reduced degree of wakefulness.
