Abstract:
A wearable blood analyte measurement device includes a casing defining an appendage- receiving bore and having an interior volume. A plurality of magnets is within interior volume. The magnets produce a magnetic field in the bore. A nuclear magnetic resonance (NMR) transceiver is supported by the casing and positioned to emit radiofrequency (RF) pulses to and receive NMR signals from the bore. An electronics assembly is within the interior volume and in communication with the NMR transceiver. A power source is in the interior volume and powers the NMR transceiver and the electronics assembly.
Abstract:
A wearable exercise and performance assessment system in which a harness adapted to be attached to the torso of a wearer. The harness comprises a mount for releasably mounting an electronics module housing at a predetermined location on the torso of the wearer. The electronics module housing comprises a plurality of motion sensors. A processor, e.g. within the housing, processes received sensor data signals and outputs a resulting feedback signal to a performance feedback device. The processor comprises a sensor signal receiver arranged to receive motion sensor data signals over time from the plurality of motion sensors and to log the received signals with a synchronised time signal. One or more of said received sensor data signals is processed to identify data features therein indicative of repeated movements by the wearer and to delineate each repetition thereof. The processor applies said repetition delineation to one or more further received motion sensor data signal in order determine a performance parameter for each individual repetition thereof.
Abstract:
A sensor apparatus comprises a housing, a flexible support structure carried by the housing and a sensor for sensing movement of a contact portion. The sensor is adapted to move relative to the housing. The apparatus further comprises a positioning system for adjusting the in-plane position of the support structure and sensor relative to the housing. This sensor design makes use of a support structure to decouple the sensor from the housing, so that there is a low inertial mass of the sensor, and hence a high sensitivity. In addition, a positioning system enables the signal to noise ratio to be maximized for a given placement of the housing, by enabling adjustment of the sensor position within the housing.
Abstract:
A garment for sensing three-dimensional motion includes a form-fitting garment article having compression areas for maintain positions of tracked areas over the user's body. Motion sensors positioned at the tracked areas are operable to capture 3D motion. A method of processing the motion data includes receiving orientation information captured by two inertial sensors and adjusting a rotation matrix for one of the sensors based on the rotation matrix for the other of the sensors. Another method of processing the motion data includes receiving orientation information captured by an inertial sensor and receiving stretch signal captured by a stretch sensor and correcting a first rotation matrix for the inertial sensor based on a flexion angle represented by the stretch signal. Another method of processing the motion data includes receiving orientation information captured by two inertial sensors and receiving stretch signal captured by a stretch sensor and correcting rotation matrices for the inertial sensors based on a flexion angle represented by the stretch signal.
Abstract:
The invention relates to a method and system for determining the condition of an animal. Movements of the animal are measured during a defined time period. The movements are converted into a movement signal that represents the measured movements. A frequency spectrum of the movement signal is determined. The frequency spectrum is subdivided into a plurality of frequency subregions. For a plurality of the frequency subregions, per frequency subregion, the amount of energy in the respective frequency subregion is determined. For each of a plurality of frequency subregions, the determined amount of energy in the respective frequency subregion is compared with each of a plurality of expectation values for the amount of energy in the frequency subregion, each expectation value belonging to one condition of a plurality of conditions of the animal, for determining the current condition of the animal.
