Abstract

A prosthetic foot comprising a foot part, a proximal connecting member which is swiveled to the foot part and an adjustment device with which the foot part can be adjusted relative to the connecting member, and at least one position sensor being associated with the adjustment device and being coupled to a signal generating element.

First claim

The invention claimed is:

1. A method for adapting a heel height of a prosthetic foot to a shoe, the prosthetic foot comprising a foot part, a proximal connection member pivotally connected to the foot part, an output device, a control device, and at least one position sensor, the method comprising:
assigning a heel height marking to the shoe, the heel height marking representing a value of a heel height of the shoe;
assigning a position signal to the heel height marking;
transmitting the value of the heel height of the shoe to the control device;
adjusting the heel height of the prosthetic foot at least partially based on the heel height marking;
comparing, with the control device, the value of the heel height marking with detected position data from the at least one position sensor; and
emitting a confirmation signal with the output device when the position signal assigned to the heel height marking matches with the detected position data, wherein the confirmation signal is an acoustic signal, the acoustic signal including at least one of different pitch levels, signal patterns, or signal sequences assigned to specific heel height levels of the foot part.

2. The method as claimed in claim 1 , further comprising:
automatically reading the heel height marking with the at least one position sensor; and
transmitting the value of the heel height marking to the control device.

3. The method as claimed in claim 1 , wherein the prosthetic foot further comprises an adjustment device, the method further comprising:
displacing, with the adjustment device, the connection member relative to the foot part,
the adjustment device being operable without the use of a motor.

4. A method for adjusting a heel height of a prosthetic foot to a shoe, the prosthetic foot comprising a foot part and a proximal connection member pivotally connected to the foot part, an output device, and an adjustment device, the adjustment device including at least one position sensor and being operable to adjust a position of the foot part relative to the proximal connection member, the method comprising:
detecting a position of the foot part relative to the proximal connection member;
generating an output with the output device as a function of the detected position, the output informing a user of the prosthetic foot about a position of the foot part relative to the proximal connection member, wherein the output is an acoustic signal, the acoustic signal generated by a voice generating device and including an announcement about a heel height level of the foot part.

5. The method as claimed in claim 4 , wherein the output device is configured to generate at least one of optical, tactile and acoustic outputs.

6. The method as claimed in claim 4 , wherein the adjustment device comprises latch elements operable to provide adjustment of the foot part relative to the connection member in discrete steps.

7. The method as claimed in claim 4 , wherein the at least one position sensor is configured as at least one of a location sensor, a relative angle sensor, an inertial angle sensor or a switch.

8. The method as claimed in claim 4 , wherein the at least one position sensor comprises an adjustable or programmable signal generator.

9. The method as claimed in claim 4 , wherein the adjustment device is operable without the use of a motor.

10. The method as claimed in claim 4 , wherein the output includes a confirmation that the foot part has reached a setpoint position, the setpoint position being a heel height.

11. The method as claimed in claim 4 , wherein the output is a tactile signal vibration, the tactile signal vibration including a pattern associated with heel height levels of the foot part.

12. The method as claimed in claim 4 , wherein the output is an optical signal, the optical signal including at least one of a light signal, a light signal pattern, or information presented on a display.

13. The method as claimed in claim 5 , wherein one or more of the optical, tactile and acoustic outputs are provided individually or in combination with each other.

14. The method as claimed in claim 4 , wherein the output includes different types of output for different heel height levels.

15. The method as claimed in claim 4 , wherein the output is an optical signal, the optical signal including different colors for different heel height levels.

16. A method for adjusting a heel height of a prosthetic foot to a shoe, the prosthetic foot comprising a foot part, a proximal connection member connected to the foot part, an output device, and an adjustment device to adjust the foot part relative to the connection member without the use of a motor, the adjustment device including at least one position sensor, the at least one position sensor being coupled to the output device, the method comprising:
detecting, with the at least one sensor, an adjusted position of the foot part relative to the proximal connection member;
generating a position signal;
communicating, with the output device, an acoustic output to a user confirming, based on the position signal, that a setpoint position for the foot part has been reached, wherein the setpoint position is at least partially determined by a heel height of the shoe, wherein the acoustic signal includes a different tone for each heel height level of the foot part.

17. A method for adapting a heel height of a prosthetic foot to a shoe, the shoe comprising a heel height marking representing a heel height of the shoe, the prosthetic foot comprising a foot part, a proximal connection member pivotally connected to the foot part, an output device, a control device, and at least one position sensor, the method comprising:
receiving a value of the heel height marking, the heel height marking representing a value of a heel height of the shoe;
assigning a position signal to the heel height marking;
transmitting the value of the heel height of the shoe to the control device;
adjusting the heel height at least partially based on the heel height marking;
comparing, with the control device, the value of the heel height marking with detected position data from the at least one position sensor; and
emitting a confirmation signal with the output device when the position signal assigned to the heel height marking matches with the detected position data.

18. A method for adapting a heel height of a prosthetic foot to a shoe, the shoe comprising a heel height marking representing a heel height of the shoe, the prosthetic foot comprising a foot part, a proximal connection member pivotally connected to the foot part, an output device, a control device, and at least one position sensor, the method comprising:
transmitting a value of the heel height marking from the shoe, the heel height marking representing a value of a heel height of the shoe;
receiving, by the control device, the heel height marking;
assigning a position signal to the heel height marking;
transmitting the value of the heel height of the shoe to the control device;
adjusting the heel height at least partially based on the heel height marking;
comparing, with the control device, the value of the heel height marking with detected position data from the at least one position sensor; and
emitting a confirmation signal with the output device when the position signal assigned to the heel height marking matches with the detected position data.

19. A method for adapting a heel height of a prosthetic foot to a shoe, the shoe comprising a heel height marking representing a heel height of t
