  • Patent number: 11657120
    Abstract: A method and an apparatus for determining at least one smoothed data point (tk, sk) within a stream of data points {ti, si} with 1?i?z, k<z is disclosed. Herein, the stream of data points {ti, si} is consecutively acquired in a manner that a data point (ti, si) is acquired after an acquisition of a preceding data point (ti?1, si?1), wherein each data point (ti, si) comprises a valid value or an invalid value or a missing value for the signal si at a time ti. Herein, the signal si at the time ti comprises physical, chemical, biological, environmental, and/or technical data acquired by means of a technical set-up. According to the method, a set of data points is provided, wherein for each smoothed data point (tk, sk) a smoothing set is created. For each smoothed data point (tk, sk), trailing data resulting from large gaps are removed until it is verified whether the smoothing set comprises a minimal number of data points.

  • Publication number: 20230011856
    Abstract: An arrangement for operating a biosensor emitting radiation includes an excitation light source, which generates at least one excitation radiation for the biosensor; a coupling fiber, at the entry surface of which the excitation radiation is coupled in; an optical Y-coupler, including an excitation arm, which is connected to the exit surface of the coupling fiber, a detector arm, which is connected to an optical detector, and a sensor foot, which can be connected to the biosensor. The excitation arm has a conical shape. The radiation axis of the excitation arm includes an angle in the range of 5° to 70° with the main radiation axis of the detector arm. The diameter of the excitation arm at the connecting point to the detector arm is less than two thirds the diameter of the detector arm. An arrangement for determining the glucose content blood is also provided.

  • Publication number: 20220192544
    Abstract: The invention relates to a method in particular for continuously determining a current glucose value in a transported fluid, in particular blood, of an organism, having the steps of: a) ascertaining a series of measurements, comprising at least two measurement values separated by time intervals, for a tissue glucose value in the tissue surrounding the transported fluid using a sensor device, b) ascertaining the tissue glucose value using the ascertained series of measurements on the basis of a sensor model, wherein measurement values of the sensor device are assigned to tissue glucose values while taking into consideration measurement noise using a sensor model, c) providing a state transition model, the ascertained tissue glucose values being assigned at least one glucose value in the transported fluid using the state transition model while taking into consideration process noise, and d) ascertaining the current glucose value on the basis of the provided state transition model and the ascertained tissue gluc

Herein, the stream of data points {ti, si} is consecutively acquired in a manner that a data point (ti, si) is acquired after an acquisition of a preceding data point (ti-1, si?1), wherein each data point (ti, si) comprises a valid value or an invalid value or a missing value for the signal si at a time ti. Herein, the signal si at the time ti comprises physical, chemical, biological, environmental, and/or technical data acquired by means of a technical set-up.

For each smoothed data point (tk, sk), trailing data resulting from large gaps are removed until it is verified whether the smoothing set comprises a minimal number of data points.
