The acceleration unit is attached or held by a body region of a mammal comprises a 3D-acceleration sensor and a wireless transmitter for transmitting a measurement signal provided by the acceleration sensor continuously. The processing unit processes the measurement signal continuously in a band of a medically defined movement of the body region, forms a movement index on the basis of a norm of values of acceleration in a first time window, and forms a value(s) of amplitude, and/or a value of frequency of the spatial movement of the body region on the basis of a power spectral density in second time window of a known duration. The display displays said movement index with said value of amplitude, and/or said value of frequency of the spatial movement continuously in real time.Type: GrantFiled: October 28, 2019Date of Patent: July 6, 2021Assignee: HEAD INSTRUMENTS OYInventors: Jani Katisko, Ossi Kumpula

Patent number: 11051726Abstract: Systems and methods for processing sensor analyte data are disclosed, including initiating calibration, updating calibration, evaluating clinical acceptability of reference and sensor analyte data, and evaluating the quality of sensor calibration. The sensor can be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. Reference data resulting from benchtop testing an analyte sensor prior to its insertion can be used to provide initial calibration of the sensor data. Reference data from a short term continuous analyte sensor implanted in a user can be used to initially calibrate or update sensor data from a long term continuous analyte sensor.Type: GrantFiled: January 28, 2021Date of Patent: July 6, 2021Assignee: DexCom, Inc.Inventors: Apurv Ullas Kamath, Jack Pryor, Paul V. Goode, Jr., James H. Brauker, Aarthi Mahalingam
