  • Patent number: 11490817
    Abstract: A non-invasive optical measurement system comprises a two-dimensional array of photonic integrated circuits (PICs) mechanically coupled to each other. Each PIC is configured for emitting sample light into an anatomical structure, such that the sample light is scattered by the anatomical structure, resulting in physiological-encoded signal light that exits the anatomical structure. Each PIC is further configured for detecting the signal light. The non-invasive optical measurement system further comprises processing circuitry configured for analyzing the detected signal light from each of the PICs, and based on this analysis, determining an occurrence and a three-dimensional spatial location of the physiological event in the anatomical structure.

  • Patent number: 11369283
    Abstract: A method is described for estimating skin thickness over an implanted magnet. A plane is defined that is perpendicular to the skin of a patient over an implanted magnet and characterized by x- and y-axis coordinates. The magnetic field strength of the implanted magnet is measured using an array of magnetic sensors on the skin of the patient. From the measured magnetic field strength, at least one x-axis coordinate in the plane is determined for at least one y-axis zero position on the array where a y-axis component of the measured magnetic field strength is zero. From that, a y-axis coordinate of the at least one y-axis zero is calculated as a function of the at least one x-axis coordinate, such that the y-axis coordinate represents thickness of the skin over the implanted magnet.
