20080276725 | Sensor Assembly for Measuring Forces and/or Torques and Use of Said Assembly - A sensor assembly is provided for measuring forces and/or torques which are transmitted by means of a rigid transmitter having a first part and a second part. The sensor assembly includes a first connection, a second connection, electromechanical sensor elements, a first flange, a second flange and a plurality of struts. The first and second connections are connectable to the first and second parts of the transmitter, respectively. The electromechanical sensor elements convert mechanical parameters into electrical parameters. The first flange surrounds the first connection and originates at the first connection. The second flange is aligned substantially parallel to the first flange. The second connection is arranged on the second flange and has a first surface and a second surface. The plurality of struts are substantially perpendicular to the first flange and connect the first flange to the second flange. A gap is formed between the first flange, the second flange and the struts, and is larger than a width of the struts. The electromechanical sensor elements are designed for determining strains or compressions and are arranged next to the plurality of struts on at least one of the first and second surfaces of the second flange. | 11-13-2008 |
20080287834 | Method for Carrying Out a Functional Analysis of an Artificial Extremity - A method for carrying out a functional analysis on a person equipped with an artificial extremity having adjustable settings. The method includes the steps of providing a sensor assembly configured as a replacement for a part of the artificial extremity and installing the sensor assembly in place of the part. Forces, accelerations and/or torques are then measured with the sensor assembly during use of the artificial extremity by the person and the settings of the artificial extremity are optimized based on these measurements. The sensor assembly is removed and the replaced part is installed back into the artificial extremity, while retaining the optimized settings. In one embodiment, the artificial extremity is a leg prosthesis having an artificial knee joint with a rotational adaptor mounted above it. The sensor assembly then replaces the rotational adaptor. | 11-20-2008 |
20090012630 | Artificial Foot And Method For Controlling The Movement Thereof - An artificial foot having a longitudinal axis extending from a heel area to a toe area, a length, a width and a height is provided. The artificial foot includes a connection to a lower leg part, an upper supporting structure in the direction of height, an elastic sole structure extending from the heel area to the toe area, an elastic connecting element arranged between the upper supporting structure and the sole structure, and a coupling system. The upper supporting structure is connected to the sole structure approximately in a middle of the foot with respect to its length by means of the coupling system. The coupling system allows a relative tilting motion between the upper supporting structure and the sole structure while keeping a distance between the upper supporting structure and the sole structure in a middle of the coupling system constant, at least while a patient places weight on it when standing. | 01-08-2009 |
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 |
20090171468 | CONTROL OF A PASSIVE PROSTHETIC KNEE JOINT WITH ADJUSTABLE DAMPING - The invention relates to the control of a passive prosthetic knee joint with adjustable damping in the direction of flexion such that a prosthetic unit attached to the knee joint can be adapted for climbing stairs. | 07-02-2009 |
20090292370 | Device for adjusting the configuration of a modular prosthetic leg - The invention relates to a device for adjusting the configuration of a modular prosthetic leg, the leg prosthesis having a foot section, a lower leg section and a knee joint, and the knee joint being disposed via a lower part on the lower leg section and an upper part being joined in an articulated manner with the lower part, having a frame and at least one fixing device disposed on the frame for fixing the foot section and the knee joint, an adjustable bracket for a thigh shaft being attached to the frame and holding a thigh shaft that is attached to the upper part of the prosthesis in its orientation with respect to the knee joint. | 11-26-2009 |
20100191347 | ORTHOPEDIC FLUID DAMPER - The invention relates to an orthopaedic aid, in particular to a prosthesis ( | 07-29-2010 |
20100228360 | CONTROL OF A PASSIVE PROSTHETIC KNEE JOINT WITH ADJUSTABLE DAMPING - The invention relates to the control of a passive prosthetic knee joint with adjustable damping in the direction of flexion such that a prosthetic unit attached to the knee joint can be adapted for climbing stairs. | 09-09-2010 |
20100305716 | METHOD FOR CONTROLLING AN ORTHOPEDIC JOINT - The invention relates to a method for controlling an orthopedic joint of a lower extremity in at least one degree of freedom by means of an adjustable actuator for adjusting an orthopedic apparatus to walking situations that differ from walking on a plane. Said orthopedic apparatus comprises top connecting means to a limb and an orthopedic element that is hingedly arranged distal to the connecting means. The method encompasses the following steps:—several parameters of the orthopedic apparatus are sensed by means of sensors;—the sensed parameters are compared with criteria that have been established based on several parameters and/or parameter curves and are stored in a computer unit;—a criterion is selected that is suitable on the basis of the determined parameters and/or parameter curves; and—resistances to movements, extents of movements, driving forces, and/or the progresses thereof are adjusted in accordance with the selected criterion in order to control special functions that differ from walking on a plane. | 12-02-2010 |
20110087339 | ORTHOPEDIC KNEE JOINT AND METHOD FOR CONTROLLING AN ORTHOPEDIC KNEE JOINT - The invention relates to an orthopedic knee joint, comprising an upper part ( | 04-14-2011 |
20130006388 | ORTHOPEDIC KNEE JOINT AND METHOD FOR CONTROLLING AN ORTHOPEDIC KNEE JOINT - An orthopedic knee joint having an upper part with upper connecting features, a lower part which is mounted pivotably on the upper part and has connecting features for prosthetic components, and a stop for limiting an extension movement. The stop and is coupled to an adjusting device, which is coupled to a control device that actuates the adjusting device as a function of sensor data and changes the position of the stop. If the knee joint is provided with an adjustable extension stop position, the extension stop can be shifted forward for walking, which results in a greater inclination at heel strike in order to flex the knee joint and, therefore, increased damping upon initiation of the stance phase. For standing, the adjusting device can be activated so that the extension stop is reversed, such that a statically more secure orthosis or prosthesis set-up can be obtained. | 01-03-2013 |
20150038878 | DEVICE AND METHOD FOR DETERMINING AND DISPLAYING FORCES - The invention relates to a method for determining and displaying horizontal and vertical forces which act on a person when standing, in which method the person stands on two separate force measurement plates coupled to each other, wherein each foot is positioned on a respective force measurement plate, and the respective support point on the force measurement plate is determined via the force measurement plates, wherein a resulting force vector (FRR, FRL) is calculated from the respective support points of the two force measurement plates, from a known point of gravity of the body and from a vertical force distribution of the two force measurement plates relative to each other, and is displayed using a display device. | 02-05-2015 |
