Abstract: A biokinetic analysis system is used to analyze the movement of a human subject, and coordinate the foot motion with the body motion. The subject walks upon an instrumented walkway, and sensors detect pressure of the subject feet. A 3D camera is aligned with a target on the walkway, and captures movement of the subject body toward the camera. The camera lenses are spaced apart vertically. Data from the walkway and data from the camera are captured simultaneously, and sent to a computer to analyze and store. Electrical power is supplied alternately by an electrical storage battery, or a photovoltaic module, or the grid. A unitary interface module electrically connects conductors to the battery, the photovoltaic module, the walkway, the camera, and the computer. The unitary interface module also digitally connects the walkway, the camera, and the computer, conveying power and data simultaneously. A transport case is provided.

Abstract: A modular instrumented floor covering assembly is used in connection with a subject walking across the assembly. The floor covering assembly comprises a plurality of sensor panels attached together along interlocking edges. The edges are held together by interlocking strips or by magnets. Each sensor panel has a pressure sensor matrix responsive to the weight of the subject for generating data relating to movement of the subject. The sensor panels are assembled on the floor selectively and releasably in patterns. No tools are needed for assembly. Data is sent wirelessly between the sensor panels and from the sensor panels to a computer for analysis. A power supply, wiring grid, and releasable connectors on the panel edges supplies electrical power to the sensor panels and between adjacent sensor panels.

Abstract: Provided is a method, system and computer readable-medium to evaluate lameness in a four-legged animal. The method includes selecting a gait analysis test. Test data associated with the animal is collected for a plurality of gait cycles at a speed associated with the test. The test data is collected in relation to a pressure sensor pad having a plurality of sensors. A plurality of paws and associated paw pressure of the animal are identified in association with each of the cycles in relation to the sensor pad. A gait lameness score is computed in association with a paw based on a ratio of, a total paw pressure for the paw in the plurality of gait cycles divided by total pressure for the plurality of paws in the plurality gait cycles, and a mean paw pressure for the paw that is expected by a breed of the animal.

Abstract: A canine gait analyzer is used in connection with a treadmill. A sensor assembly includes a plurality of overlapping sensor panels, each having a pressure transducer array connected to a circuit board with conductive traces. An elastomer sheet with carbon-graphite dampens the dog's pawsteps, and is electrically grounded for static electric charge. The sensor assembly is held fast between the belt inner surface and the treadmill bed with a J bracket. The sensor panel edge extends downward on the side of the frame. A C-shaped side cover is attached to the frame and covers the sensor panel edge having the circuit boards. A motor speed controller is connected to the motor, the circuit boards, and to a computer.

Abstract: An arrangement for the rehabilitation of a limb includes a motion capture device a control module and a gait device coupled to the control module. An affected limb is attached to the gait device so that when the user moves an unaffected limb, the motion capture device records the movements of the unaffected limb and transmits such data to the control module which in turn sends controls to the gait device to assist the movement of the affected limb.

Abstract: A nipped roller impression sensor system comprising a first roller having an axis of rotation and a surface and a second roller having an axis of rotation that is substantially parallel to the axis of rotation of the first roller, wherein the second roller is disposed so that a surface of the second roller exerts pressure on the surface of the first roller at a nip having a width. The nipped roller impression sensor system also comprises at least one pressure sensor device configured to be disposed at the nip between the first and second rollers. The pressure sensor device comprises a resistive electrode maintained in a non-conductive arrangement with a shunt electrode by at least one spacer element, such that a width of the nip corresponds to a change in resistance across the resistive electrode when the second roller exerts pressure on the first roller.
