Abstract: Systems and methods are disclosed for sensing forces, moments, temperature, inclination, acceleration and other parameters associated with prosthetic limbs. The system is capable of measuring forces in three designated axes, and moments about the same designated axes, for a total of six possible degrees of freedom. The system can be readily fitted onto a conventional prosthetic limb with no, or relatively minor, modification thereto. A plurality of sensor arrays are disposed on a support member, each array including a plurality of strain gauge sensors, each sensor outputting an electrical signal responsive to loading imposed on the support member through the prosthetic limb. Electronic circuitry in communication with the gauges is operative to receive the electrical signals from the strain gauges and provide a signal useful in the form, fit or function of the prosthetic limb.

Abstract: A system for removing a protection associated with an account of a customer that prevents a change of a service provider of the customer includes a database server configured to receive a request from a prospective service provider of the customer to remove the protection associated with the customer's account when authorization of the customer is required to effect the change of the service provider. The request includes an electronic address of an audio file including a customer's authorization to remove the protection. The system also includes a computer configured to access the audio file based on the electronic address and to indicate whether to remove the protection based on the audio file, and a customer care ordering system configured to remove the protection when the computer indicates that the protection is to be removed.
