Abstract: A method of calibration of a system designed for analysis of ground reaction forces of a user's feet, wherein the system comprises a left and right footwear each with a plurality of force sensors. The method includes (a) obtaining respective data measurements from each force sensor over a time period while the user's feet are in the left and right footwear; (b) determining a respective statistic of the respective data measurements for each force sensor over the time period; and (c) storing the respective statistic as a respective calibration offset for a respective force sensor. The respective statistic may comprise a minimum, a maximum, an average, a median, a percentile, and/or a statistical model of the respective data measurements.

Abstract: A method of calibration of the motion and force processing system designed to analyze user's feet motion in relation to the ground reaction forces wherein the system comprises multiplicity of motion and force sensors embedded in the insole of a footwear and wherein the calibration is intended to compensate for errors in fabrication and assembly of the sensors, insoles, footwear and for the user's natural pronation, in a single procedure.

Abstract: A system for analysis of user gait and foot disorder intended to minimize risks ulceration and limb amputation associated with the uncontrolled increase of the foot temperature in persons with diabetes. This system comprises a motion, force and temperature sensors and a processing element configured to process motion algorithms, measure ground reaction force (GRF) and changes in foot temperature embedded in the footwear insoles in communication with a smartphone based analysis application using wireless radio interface. The analysis application processes data received from the footwear sensors, compares the results with set of criteria and rules, and if any of the predefined criteria is exceeded, provides alerts to the user and the remote medical supervisor. Additionally, the insoles may be equipped with a haptic actuators configured to determine the level of the user neuropathy by measuring vibration perception threshold (VPT) level.

Abstract: A method allowing the synchronizing collection of motion and ground reaction forces data at the start of a sporting event which are received from motion and force sensors embedded in insoles worn in the user's footwear. Furthermore, this method allows synchronization of said data with video or television transmission, and if used during, for example, during ski racing, provides information of skis' pitch, roll and heading in a 3-D space, as well as linear and angular velocity, g-forces, and the location and distribution of pressure points and ground reaction forces transferred to the user's feet in a numerical or a graphical form.
