Abstract

A prosthetic arm apparatus including a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a prosthetic support apparatus that may be adorned by the user. Some segments may provide movement about more than one axis using a single actuator. The prosthetic arm apparatus may include a user interface incorporated therein and may include one or more communication systems for communicating with external devices.

The prosthetic limb includes at least one antenna in connection with the controller for transmitting and receiving signals. The at least one antenna including the housing of the prosthetic limb segment as a radiating element. The prosthetic limb further includes a user interface integrally formed in the housing. The user interface including a status indicator for displaying information and having a flexible protective cover disposed around a portion of the housing and covering the user interface, the flexible protective cover including a translucent portion over the status indicator.

Claims

1. A prosthetic limb segment comprising:

a housing defining an exterior of the prosthetic limb segment, the housing having an input interface and an output interface, the output interface and input interface being moveable with respect to one another;

a motorized drive disposed within the housing, the motorized drive effecting movement of at least one of the output interface or the input interface;

a controller disposed within the housing for controlling actuation of the motorized drive; and

at least one antenna in connection with the controller for transmitting and receiving signals, the at least one antenna including the housing of the prosthetic limb segment as a radiating element;

wherein the controller is adapted to be in communication with at least a second motorized drive disposed within a second housing defining an exterior of a second prosthetic limb segment to control actuation thereof.

2. The prosthetic limb segment according to claim 1, additionally comprising a user interface integrally formed in the housing and in communication with the controller.

3. The prosthetic limb segment according to claim 2, wherein the user interface includes a status indicator having at least one LED for displaying information from the controller.

4. The prosthetic limb segment according to claim 3, wherein the LED displays a current mode of operation.

5. The prosthetic limb segment according to claim 3, wherein the LED provides a low power alert.

6. The prosthetic limb segment according to claim 3, wherein the LED provides a system failure alert.

7. The prosthetic limb segment according to claim 2, wherein the user interface includes a status indicator having a plurality of LEDs for displaying information from the controller.

8. The prosthetic limb segment according to claim 7, wherein at least a portion of the plurality of LEDs are arranged in an array for displaying operational mode information from the controller.

9. The prosthetic limb segment according to claim 2, wherein the user interface includes at least one input member for providing a signal to the controller.

10. The prosthetic limb segment according to claim 9, wherein the signal causes the controller to alter information being displayed on a status indicator.

11. The prosthetic limb segment according to claim 2, wherein the user interface includes a protective cover.

12. The prosthetic limb segment according to claim 11, wherein at least a portion of the protective cover is flexible to allow actuation of an input member disposed beneath the protective cover.

13. The prosthetic limb segment according to claim 11, wherein at least a portion of the protective cover is translucent to allow light from an LED disposed beneath the protective cover therethrough.

14. The prosthetic limb segment according to claim 1, wherein the housing is electrically connected to an antenna matching network circuit of the controller and is electrically isolated from a remainder of the controller.

15. A prosthetic limb device comprising:

a first prosthetic limb segment comprising;

a housing defining an exterior of the prosthetic limb segment, the housing having an input interface and an output interface, the output interface and input interface being moveable with respect to one another;
