CONTROL SYSTEMS AND METHODS FOR PROSTHETIC OR ORTHOTIC DEVICES
First Claim
1. A method for controlling an adjustable prosthetic or orthotic device, the method comprising:
- measuring with a geo-magnetic sensor a plurality of data points over a time interval, wherein the plurality of data points provides orientation data information of a prosthetic or orthotic device with respect to the earth'"'"'s magnetic field;
processing the plurality of data points over the time interval by comparing the orientation data information with predefined unsafe gait patterns; and
outputting control instructions to the prosthetic or orthotic device when the orientation data information matches one of the predefined unsafe gait patterns.

Abstract
Geomagnetic methods and systems are used for monitoring the directionality of a prosthetic or orthotic device. Certain methods may include measuring multiple data points over a particular time interval to identify orientation information with respect to a prosthetic or orthotic device and/or used in the real-time control of the prosthetic or orthotic device. In certain examples, multiple points may be further compared with stored orientation data associated with predefined unsafe gait patterns. Control instructions and/or alerts based on the geomagnetic measurements can then be generated for the prosthetic or orthotic device, such as if the orientation data information matches one of the predefined unsafe gait patterns.
