Feedback control systems and methods for prosthetic or orthotic devices
First Claim
1. A method for automatically adjusting a prosthetic or orthotic device, the method comprising:
- detecting a stationary position of a user of a prosthetic or orthotic device attached to the user;
identifying with circuitry operatively coupled to the prosthetic or orthotic device a first geographic location identifying at least one of a longitude or latitude of the prosthetic or orthotic device based on information received at a first time from a transmitting source located remotely to the prosthetic or orthotic device;
identifying with the circuitry a second geographic location identifying at least one of a longitude or latitude of the prosthetic or orthotic device based on information received at a second time from the transmitting source;
calculating with circuitry a velocity of the prosthetic or orthotic device based on a distance between the first and second geographic locations over a duration of time between the first time and the second time while the user is in the stationary position;
comparing with circuitry the calculated velocity to a threshold velocity; and
when the calculated velocity of the prosthetic or orthotic device exceeds the threshold velocity while the user is in the stationary position, automatically adjusting with circuitry a state of operation of the prosthetic or orthotic device.

Abstract
Methods and systems are used for monitoring a global position or location of a prosthetic or orthotic device and to provide feedback control of the device. Certain methods may employ remote transmitting devices and receivers to recognize when a prosthetic or orthotic device user is in a moving vehicle and, therefore, initiate automatic shut-off, driving mode, or relaxed mode. Other methods may employ remote transmitting devices and receivers to identify the global position of the prosthetic or orthotic device, compare the global position to a stored terrain mapped database and output feedback control instructions and/or alerts to the prosthetic or orthotic device based at least in part on the stored terrain mapping information.

10. A method for actively adjusting a lower limb prosthetic or orthotic device, the method comprising:
- determining a global location of the prosthetic or orthotic device user based on data wirelessly received from a transmitter remotely located to the prosthetic or orthotic device;
comparing the determined global location to environmental data related to the determined global location that was previously stored in a memory prior to the device reaching said determined global location, wherein said environmental data is indicative of environmental variables corresponding to a plurality of known global locations and comprises population density information; and
actively adjusting with at least one actuator movement of the prosthetic or orthotic device based at least in part on said comparison. - View Dependent Claims (11, 12, 13, 14, 15)
