Abstract: Disclosed is a computer-implemented method. The method comprises processing, by at least one computing device, exercise measurements taken by a pressure sensor positioned adjacent to a pelvic floor muscle (PFM) of a person at least during performance of a physical exercise, wherein the exercise measurements are indicative of a pressure exerted on the pressure sensor and an orientation of the sensor. The method also comprises calibrating, by the at least one computing device, the pressure of the processed exercise measurements at least based on the orientation of the processed exercise measurements.

Abstract: Disclosed is a computer-implemented method. The method comprises processing, by at least one computing device, first measurements taken at least while a person performs a predetermined physical exercise, wherein the first measurements are taken by at least one motion tracking device, at least one optical sensor, or both. The method also comprises processing, by the at least one computing device, second measurements taken at least while the person performs the predetermined physical exercise, wherein the second measurements are taken by a pelvic sensor. The method also comprises determining, by at least one computing device, whether the person has performed the predetermined physical exercise based on the first measurements and the second measurements according to criteria associated with the predetermined physical exercise.

Abstract: A method comprising: wirelessly receiving, at a first device, at least one data packet from each second device of a plurality of second devices arranged at predetermined locations of a target; detecting an angle of arrival of each at least one data packet wirelessly received of at least a pair of second devices; calculating at least one angle difference between the angles of arrival associated with the pair of second devices, or between the angles of arrival associated with each of the pair of second devices and a predetermined direction; and determining whether the target is at a predetermined distance range from the first device by estimating the distance based on the at least one angle difference, and a predetermined distance between the predetermined locations; or checking whether each of the at least one angle difference is within a predetermined angle range for the predetermined locations of the pair of second devices. Also, a method for making such determination based on angles of departure.

Abstract: A method: includes the following steps: processing, by a computing device, at least a stretch value per strap of straps of a motion tracking system; comparing, by the computing device, the stretch value of each strap or a length value derived therefrom with a stored baseline value of the respective strap, the stored value being associated with the same person, and the length value being representative of a length of a respective strap at least based on the respective stretch value. The method further includes executing, by the computing device, a corrective action at least when one of the comparisons made exceeds a predetermined threshold. Also, a motion tracking system, a data processing device, a computer program, and a computer-readable medium are related.
