  • Patent number: 9681830
    Abstract: A device for detecting a vital parameter is described, comprising: an optoelectronic sensor arrangement for detecting the vital parameter by means of light remission at a finger, wherein the optoelectronic sensor arrangement has a first light source for generating light in a visible wavelength range, a second light source for generating light in a non-visible wavelength range and a light-sensitive element; and a controller which is implemented to switch on the second light source in temporal intervals, execute an evaluation of the light received from the light-sensitive element in the invisible wavelength range of the second light source with respect to whether a finger is applied to the optoelectronic sensor arrangement and to switch on the first light source as soon as the evaluation indicates that a finger is applied to the optoelectronic sensor arrangement.

  • Patent number: 9119536
    Abstract: A pressure gauge for determining at least one pressure value describing a pressure of a fluid flowing in a pulsating manner in a phase of the pulsating flow, includes a pulse wave characterizer. The pulse wave characterizer is configured to obtain transmit time information of a pulse wave, and amplitude information of the pulse wave. The pressure gauge additionally includes a pressure value determiner configured to obtain a first pressure value describing a pressure of the fluid in a first phase, on the basis of the transmit time information and while using a mapping. The pressure value determiner is further configured to obtain a second pressure value describing a pressure of the fluid in a second phase, on the basis of the first pressure value and the amplitude information while using a mapping.

  • Publication number: 20100286546
    Abstract: A garment for detecting respiratory movement of a living being, wherein the garment can be pulled over the thorax of the living being, including an electric conductor integrable at the height of the thorax of the living being into the garment, which is attached to the garment in order to change an electrically measurable characteristic in dependence on the respiratory movement of the thorax, and a holder for fixing evaluation electronics integrable into the garment, which can be coupled to the electric conductor and which is implemented to detect the electrically measurable characteristic and which further includes an interface for outputting or storing data derived from the electrically measurable characteristic.

  • Publication number: 20090062675
    Abstract: The beginning of an apnea can be recognized reliably if a series of sample values describing the breathing noise of a patient are processed in block-wise manner, and if a fingerprint with a predetermined number of fingerprint coefficients describing a waveform of the sample values within a block is determined for a number of sample values within the block. Since the number of fingerprint coefficients is smaller than the number of sample values within the block, comparison of the fingerprint coefficients with reference fingerprint coefficients characteristic for the waveform at the beginning of an apnea can be performed efficiently and reliably, in order to detect the beginning of the apnea.
