摘要： The present invention relates to a device, system and method for determining at least one vital sign of a subject. To solve the motion robustness problem of known solutions, the device comprises a receiver (210) configured to receive electromagnetic radiation reflected from a skin region of a subject, a polarization unit (220) configured to apply a first polarization on the received electromagnetic radiation to generate first polarized radiation and to apply a second polarization, which is different from the first polarization, on the received electromagnetic radiation to generate second polarized radiation, a sensor unit (230) configured to generate a first detection signal having a first polarization direction from the first polarized radiation and a second detection signal having a second polarization direction, which is different from the first polarization direction, from the second polarized radiation, and a vital sign determination unit (240) configured to determine a vital sign from the two detection signals by combining the two detection signals.

摘要： Presented are concepts for monitoring cardio-respiratory function of a patient. One such concept comprises detecting light or sound from the sublingual vasculature using a sublingual sensor unit adapted to be positioned at a sublingual vasculature of the patient's tongue and to generate a sensor output signal based on the detected light or sound. A processing unit adapted to receive at least one of the sensor unit output signal, wherein the sensor unit and the processing unit are arranged to analyze the venous component in the sensor output signal. An output signal from the sublingual sensor may then be used to provide information on cardio-respiratory parameters like respiration rate and respiration rate variability, for example.

The sublingual device also comprises a support unit (23) that is adapted to support the sensor unit and comprises a recess (24). The support unit is adapted to be positioned against the tissue of the patient so that it is positioned at sublingual vasculature of the patient's tongue. When the support unit is positioned against the tissue of the patient, the recess is adapted to be positioned to cover a target region of the tissue of the patient and the sensor unit is adapted to detect light or sound from the target region of the tissue of the patient, the target region of the tissue of the patient comprising sublingual vasculature.

摘要： A resistance emulation device includes a resistance emulation circuit, a controller configured to control the resistance emulation circuit to emulate a desired resistance at output terminals, a buffered voltage measurement circuit and a current measurement circuit configured to output respective measurements of electrical voltage and current at the output terminals. The controller determines a measured emulated resistance from the measurements of voltage and current over the output terminals and calibrates the control of the resistance emulation circuit to match the measured emulated resistance with the desired resistance. The controller may also convert a temperature to the desired resistance using a temperature-to-thermistor resistance conversion operation. A core body temperature (CBT) thermometer may include the resistance emulation device to emulate a thermistor resistance corresponding to a CBT measured non-invasively by the CBT thermometer using a heat flux approach.
