20120123701 | FORCE PLATFORM SYSTEM - A method of processing force signals from plural force platforms includes, in a computer, in an initialization process, receiving data distinguishing the plural platforms, monitoring force data signals from each of the plural platforms, and identifying each of the plural platforms to a force platform data process application by a sequence of received above-threshold force data signals. The method further includes, subsequent to the initialization process, processing subsequent force data signals according to the identification of each of the plural force platforms. The distinguishing data can include data retrieved from nonvolatile memory of each of the plural force platforms, such as a platform serial number, calibration data, and platform capacity. A force platform system includes one or more force platforms and force platform signal conditioning circuitry connected to the one or more force platforms. The signal conditioning circuitry may include a separate signal conditioner connected to each force platform. | 05-17-2012 |
20110118878 | SYSTEM AND METHOD FOR JOINT MOTION SIMULATION - A simulator for driving a prosthetic element includes a prosthetic drive mechanism that drive the prosthetic element during an accelerated wear test of the prosthetic element. A simulation input represents the action of the simulator and a sensor mechanism is used to measure the force and torque applied to the prosthetic element. Position and orientation control sensors are further used to measure displacement of the prosthetic element. A closed loop feedback control system, responsive to the sensors, is used to determine a drive signal for the drive mechanism. The control system advantageously adds a computational model that incorporates mechanical representations of ligament fibers. The computational model is a non-human approximation to situations that would be encountered by the prosthesis within the human body and includes dimensional geometry of insertion sites and mechanical properties of ligament fibers. The computational model is responsive to the position and angular displacement sensors to determine constraint forces and torques of ligaments that mitigate action of the control system. The action of the control system may further be mitigated by the measured force and torque | 05-19-2011 |
