Patents by Inventor Etienne Hirt

Etienne Hirt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9848781
    Abstract: The equipment has at least one pressure sensor (28) disposed for being placed onto the surface of the body of the user and being held attached thereto by means of a band. The attachment force is selected such that the pressure signal from the pressure sensor (28) contains variations caused by the pulse. An attachment pressure sensor (52) or a band tension sensor (18?) generates an electrical signal depending on the attachment pressure. The microprocessor (36) determines the diastolic and systolic blood pressure values from the pressure signal, taking into account the signal from the attachment pressure sensor (52) or the band tension sensor (18?).

  • Publication number: 20170089782
    Abstract: The strain gauge device (20) comprises an elastic band (22), the strain of which is to be measured. The sensor (26) comprises at least one elongated measuring strand (38) changing resistivity in dependence of the strain of the band (22). The measuring strand (38) is mounted with pre-tension to the band (22) by means of a layer of glue disposed between the sensor (26) and the band (22). The equipment (10) for continually measuring the blood pressure of a user comprises at least one strain gauge device (20).

  • Patent number: 8197406
    Abstract: A device for measuring the glucose level in living tissue has electrodes (5, 6) for being brought into contact with the specimen and a voltage-controlled oscillator (31) as a signal source for generating an AC voltage in a given frequency range. The AC voltage is applied to the electrodes (5, 6). A voltage over the electrodes is fed to a processing circuitry (37, 38), which converts it to the glucose level using calibration data. The voltage-controlled oscillator (31) has a symmetric design with adjustable gain for generating signals in a large frequency range with low distortions at a low supply voltage. The processing circuit comprises a simple rectifier network with software-based correction. The electrodes (5, 6) are of asymmetric design and optimized for biological compatibility.

  • Patent number: 7693561
    Abstract: For measuring the concentration of a substance in body fluid, such as the glucose level in blood or tissue, a strip electrode (18) and a ring electrode (19) are arranged at the specimen. The ring electrode (19) is in direct electrical contact with the specimen while the strip electrode (18) is electrically insulated therefrom. The strip electrode (18) is arranged parallel to an arm or a leg for obtaining a large interaction length. The electrodes (18, 19) form a capacitor in a resonant circuit. A modulated voltage in the MHz range close to or at the resonance frequency is applied to the electrodes and the response of the body fluid is measured. This design allows a measurement of high accuracy.

  • Patent number: 7315767
    Abstract: One aspect of the invention provides a device that non-invasively determines the concentration of a substance in a target. The device includes a first electrode, a measuring circuit, and a data processor. In one embodiment of the device, the first electrode can be electrically insulated from the target, e.g., a cover layer of insulating material covers the first electrode.
