20090118647 | SYSTEM AND METHOD FOR VISUALIZING GROUND REACTION FORCES ON A HUMAN BODY - The invention relates to a display system and method for measuring and displaying ground reaction forces of a human. The system comprising comprises a measurement plate having at least one sensor device for detecting ground reaction forces, which is connected to an evaluation device connected to the measurement plate and a projection device, and the invention also relates to a method for displaying ground reaction forces on a human body. The display system and the method are suitable in particular for measuring the human body and/or prosthetic or orthotic fit components in their relative position to the human body, and for improving the adjustment of a prosthesis set up. | 05-07-2009 |
20090204229 | Passive Orthopedic Aid in the Form of a Foot Prosthesis or Foot Orthosis - The invention relates to a passive orthopedic aid in the form of a foot prosthesis or foot orthosis, with a first part which is connected to a second part in a rotatable manner via a swivel joint, with a sensor arrangement for measuring parameters that provide indications of instantaneous operation requirements of the aid, with a control means which is connected to the control arrangement and is used to determine operation requirements and to generate corresponding control signals, with a controllable hydraulic damping arrangement with which a movement resistance acting on the rotation movement between the first part and the second part can be modified, and with a control means which converts the control signals of the processor arrangement and is used to control the damping arrangement. The foot prosthesis is characterized in that the damping arrangement is a dual-action hydraulic cylinder with two hydraulic chambers separated from each other by a piston, and in that the hydraulic chambers are connected via two connection lines which permit a flow of the hydraulic fluid only in mutually opposite directions and whose flow resistances can be adjusted by the control separately and via their own adjustment means each, in that the processor arrangement is configured to determine a current neutral point position from the measured parameters of the sensor arrangement, and in that the control signals for the flow resistances in the two connection lines are generated with respect to the neutral point position. | 08-13-2009 |

20120226364 | METHOD FOR CONTROLLING AN ORTHOTIC OR PROSTHETIC JOINT OF A LOWER EXTREMITY - The invention relates to a method for controlling an orthotic or prosthetic joint of a lower extremity with a resistance device to which at least one actuator is associated, via which the bending and/or stretching resistance is changed depending on sensor data. During the use of the joint, status information is provided via the sensors. The sensor data are determined by at least one device for detecting at least two moments or a moment and a force. The sensor data of at least two determined values are linked by means of a mathematical operation and at least one auxiliary variable is thus calculated, on which the control of the bending and/or stretching resistance is based. | 09-06-2012 |
20120232673 | METHOD AND DEVICE FOR CONTROLLING AN ARTIFICIAL ORTHOTIC OR PROSTHETIC JOINT - The invention relates to a device and method for controlling an artificial orthotic or prosthetic joint of a lower extremity, comprising a resistance unit with which at least one actuator is associated, via which the bending and/or stretching resistance is varied depending on sensor data. During the use of the joint, status information is provided via sensors. According to the invention, the resistance is increased in the standing phase or while standing from a starting value depending on the ground reaction force up to a locking point of the joint. | 09-13-2012 |
