  • Publication number: 20190076086
    Abstract: There is provided a method and apparatus for determining a baseline for one or more physiological characteristics of a subject. One or more physiological characteristics of a subject and contextual information associated with the subject is acquired. A time period in which the subject is in a baseline state is detected based on the acquired one or more physiological characteristics of the subject and the acquired contextual information associated with the subject. The baseline for the one or more physiological characteristics of the subject is determined from a value of at least one of the acquired one or more physiological characteristics in the detected time period.

  • Patent number: 10213114
    Abstract: A device (100) for monitoring a subject's breathing rate is disclosed. A transducer (107) radiates energy towards the chest of a subject and receives the reflected energy. An analyzer (105) receives a signal corresponding to the reflected energy. The reflected energy would have undergone Doppler frequency shifts due to the motion of the chest of the subject due to breathing, with reference to the transducer. The analyzer (105) analyzes the signal to calculate the breathing rate by measuring at least one of a periodicity of the signal and a number of cycles per unit time of the signal. In a preferred embodiment the transducer (107) is disposed in or on a sphygmomanometer cuff to radiate energy towards the chest of the subject and receive the energy reflected by the chest of the subject.

    Abstract: A system for determining a vital sign of a subject releases the likelihood of generating and outputting false alarms. The system includes a vital sign processor that processes the vital sign information signal measured by a sensor attached to a subject to obtain a vital sign of said subject. An image analysis unit detects motion of a marker attached to the sensor from image data obtained by an imaging unit from at least an imaging region containing the sensor. An alarm unit generates and outputs an alarm signal based (1) on the measured vital sign information signal and/or the obtained vital sign and (2) the detected motion of said marker.

  • Patent number: 9936920
    Abstract: Self measurements of physiological parameters such as blood pressure are prone to errors and artifacts since they are often not done according to established and standardized protocols i.e., such that predetermined conditions for a reliable measurement are not met. To determine whether the predetermined conditions for a reliable measurement are met one or more physiological and environmental sensors are used to determine a measurement context. The obtained sensor data is compared with predetermined thresholds to determine whether the context allows a reliable self test. In case the predetermined conditions are not met based on the obtained sensor data instructions are given to guide the subject that wants to do a self test.

  • Patent number: 9924879
    Abstract: The invention relates to a fever detection apparatus for detecting fever of a living being. A heart rate providing unit (3) provides a heart rate value and a peripheral physiological value providing unit (3) provides a peripheral physiological value, wherein a heart rate characteristics determination unit (4) determines heart rate characteristics from the heart rate value and a peripheral characteristics determination unit (5) determines peripheral characteristics from the peripheral physiological value. A fever detection unit (6) detects fever depending on the heart rate characteristics and the peripheral characteristics. Since the heart rate characteristics and the peripheral characteristics are influenced by fever, the fever detection apparatus can be used to reliably and preferentially unobtrusively detect fever.
