Abstract: A monitoring system and method for early detection of fall risk. A rise-state of a subject occupying a bed is detected. In response to the detection of the rise-state, blood pressure measurement of the subject is triggered. An alarm when the measured blood pressure is not within a selected range of blood pressures.

Abstract: A method and a system provides temporal information on a subject. A ballistocardiographic signal is obtained with an accelerometer, and processed to obtain a beat-to-beat time (TB2B) signal and a stroke volume (SV) signal. Filtered TB2B SV signals are provided by filtering the signals to remove erroneous values not caused by heart-beats. A true HR signal is calculated from the filtered TB2B signal and a true SV signal and a stroke volume variability (SVV) signal are calculated from the filtered SV signal. The true HR signal is filtered to detect and separate abnormal heart; the true SV and SVV signals are used as parameters to facilitate separation of the abnormal and normal heart-beats. If abnormal heart-beats are detected, arrhythmia related to the detected abnormal heart-beats is identified and temporal information on occurrence and type of the identified arrhythmia is provided to a user.

Abstract: A ballistocardiographic method and monitoring system calculates an indicator of the average heart rate of a test subject within a time interval. The test subject may be a fetus inside a mother's belly, or infant lying in the same bed as an adult. The monitoring system comprises a recoil surface and an acceleration sensor in contact with the recoil surface. A control unit identifies in the time domain the characteristics of the adult's heartbeat during the time interval. The output signal is then transformed to the frequency domain across the time interval and the signal is screened with the adult heartbeat characteristics. The indicator is then calculated from the screened signal in the frequency domain. The control unit monitors the indicator of the infant or fetus heart rate and may provide an alert if the indicator value drops very rapidly, or falls below a predetermined threshold value.

Abstract: The present invention relates to method and a system for detecting sleep phenomena, the phenomena including at least one of sleep cycles and sleep disorders such as sleep apnea and hypopnea. Ballistocardiologic signals are detected from a subject person, which provide simultaneous information on heart rate variability (HVV) and stroke volume (SV) of the subject. Values of parameters reflecting measured characteristics of currently occurring cardiologic and respiration related sleep phenomena are obtained by processing at least said ballistocardiologic signals. Obtained parameters are used for making decisions on detection of said sleep phenomena, and a monitoring result is output in response to detection of a currently occurring sleep phenomenon.

Abstract: Method and system for monitoring stress level of a subject. Beat-to-beat time variation and stroke volume variation of the heart a subject are obtained simultaneously, and a stress level indication is determined as a function of the beat-to-beat time variation and the relative stroke volume variation. More accurate and reliable estimates for stress level may be obtained.
