Abstract

A prosthesis system having at least two sensors, at least one control device, which is coupled to the sensors and processes sensor signals of the sensors, at least one actuator, which is coupled to the control device and can be activated or deactivated on the basis of control signals of the control device, and at least one movably mounted prosthesis component, which can be displaced by the actuator. A standard program, which assigns an actuator action to each sensor independently of the duration and/or intensity of the sensor signal, is stored in the control device or can be called up by the control device.

First claim

We claim:

1. A prosthesis system comprising:
at least two sensors;
at least one control device, which is coupled to the sensors and processes sensor signals of the sensors;
at least one actuator, which is coupled to the control device and can be activated or deactivated on the basis of control signals of the control device;
at least one movably mounted prosthesis component, which can be displaced by the actuator; and
a standard program, which assigns an actuator action to each sensor independently of at least one of the duration and intensity of the sensor signal, is stored in the control device or can be called up by the control device, wherein the control device is freely programmable to execute a pattern recognition, and wherein the standard program is different from an application program.

2. The prosthesis system according to claim 1 wherein the standard program operates all functions of the at least one prosthesis component.

3. The prosthesis system according to claim 1 , further comprising an energy store, which is coupled to the at least one actuator and integrated in the prosthesis system or assigned to the prosthesis system.

4. The prosthesis system according to claim 1 , wherein the sensors are configured to be touch-sensitive.

5. The prosthesis system according to claim 1 , wherein only one actuator action is assigned to each sensor.

6. The prosthesis system according to claim 1 , wherein an individual actuator action is assigned to each sensor.

7. The prosthesis system according to claim 1 , wherein the control device comprises an interface to at least one of an operating device and a display device.

8. The prosthesis system according to claim 7 , wherein a software application, which is configured to run on a processor of the operating device, is installed in the operating device, the software application being configured to display functions of the prosthesis system, to at least one of visually check and display sensor signals, to trigger actuator actions by signals sent to the control device, to output at least one of error, warning and advice messages, and to output procedural instructions for carrying out a check of the functionality of the prosthesis system.

9. The prosthesis system according to claim 1 , wherein after activation of the standard program and triggering of at least one sensor signal, the control device induces at least one actuator action and at least one of records the execution or non-execution thereof and outputs the presence or absence of a sensor signal on an output device.

10. A method for checking the functionality of a prosthesis system, the method comprising:
providing a plurality of sensors, at least one control device, which is coupled to the sensors and processes sensor signals of the sensors, at least one actuator, which is coupled to the control device and can be activated or deactivated on the basis of control signals of the control device, at least one movably mounted prosthesis component being displaceable by the actuator, and a standard program, by which an actuator action is assigned to each sensor; and
after activation of the standard program and triggering of a sensor signal, an actuator action is induced and at least one of the execution or non-execution thereof is detected and recorded and the presence or absence of a sensor signal is output on an output device, is stored in the control device or can be called up by the control device.

11. The method according to claim 10 , wherein, when a sensor signal is triggered, a prosthesis component is displaced maximally in a displacement direction.

12. The method according to claim 10 , wherein, before the execution of an actuator action, a check is made as to whether the number of sensors stored in the standard program are coupled to the control device.

13. The method according to claim 10 , wherein the sensor signals are amplified.

14. The method according to claim 10 , wherein for each executed or not executed actuator action, a report is sent to at least one of an operating device and a display device.

15. The method according to claim 10 , wherein the standard program is activated by a switch or a signal of an external operating device, before a sensor signal is received or measured.

16. The method according to claim 10 , wherein the sensor signal is sent to the control device by activation of a sensor or by an operating device.

17. The method according to claim 10 , wherein the actuator action is assigned to the respective sensor independently of at least one of the duration and intensity of the sensor signal.

18. The method according to claim 10 , wherein a plurality of sensors are activated simultaneously or successively in a predetermined period of time, and an actuator action is induced or output which differs from the actuator action which is induced or output in the event of a single activation.

19. The method according to claim 10 , wherein a software application which is configured to generate a control signal or to simulate a sensor signal, which is sent to the control device, is run on a processor.

20. The method according to claim 19 , wherein the software application is configured to display system functions on a display or to output the system function by another output device.

21. The method according to claim 19 , wherein the software application is configured to display control signals or simulated sensor signals on a display.

22. The method according to claim 19 , wherein the software application is configured to output at least one of error, warning and advice messages via an output device.

23. The method according to claim 19 , wherein the software application is configured to specify various method steps via an output device and to carry out the method steps.
