Abstract

A system and method for prosthetic/orthotic (PO) device and/or PO system communication. PO devices of the present invention may employ common communications and/or communications/control modules that allow for wireless communication between PO devices and other devices, such as remote controls and data transfer devices. The present invention also provides for a methodology of determinant and non-interfering simultaneous communication between multiple PO devices of a PO system.

Claims

1. An intercommunicating prosthetic/orthotic (PO) device system, comprising:

a first PO device in the form of an artificial limb component, said first PO device including a communications/control module having communication and control components, said communication and control components mounted to a single board and including at least a transceiver, a microprocessor, and an antenna; and

a second PO device in the form of an artificial limb component, said second PO device including a communications/control module having communication and control components, said communication and control components mounted to a single board and including at least a transceiver, a microprocessor, and an antenna;

wherein, said PO devices are adapted for wireless and bi-directional intercommunication over one or more communication channels; and

wherein, said bi-directional intercommunication is accomplished by a technique selected from the group consisting of time slicing, the use of distinct frequency sets, and the use of temporally shifted frequency sets.

2. The PO device system of claim 1, further comprising a remote control adapted for wireless communication with at least one of said first and second PO devices.

3. The PO device system of claim 2, wherein said remote control is a fob.

4. The PO device system of claim 1, wherein at least one of said PO devices is a prosthetic socket evacuation device.

5. The PO device system of claim 1, further comprising a data transfer device to which at least one of said first and second PO devices may wirelessly transmit data, said data transfer device including a communications/control module having at least a transceiver, a microprocessor, and an antenna.

6. The PO device system of claim 5, wherein said communications/control module of said data transfer device is located within a portable housing connected to a USB interface.

7. The PO device system of claim 1, wherein at least one of said first and second PO devices is adapted to employ frequency hopping within a given communication time slice.

8. The PO device system of claim 1, wherein one of said PO devices acts as a top level primary control device and the other PO device acts as a subordinate device that reports to the top level primary control device.

9. An intercommunicating prosthetic/orthotic (PO) device system, comprising:

a first PO device in the form of an artificial limb component, said first PO device including a common communications module having communication and control components, said communication and control components mounted to a single board and including at least a transceiver, a microprocessor, and an antenna, said first PO device acting as a top level primary control device; and

a plurality of additional PO devices in the form of artificial limb components, each additional PO device including a common communications module having communication and control components that are mounted to a single board and include at least a transceiver, a microprocessor, and an antenna, each additional PO device acting as a subordinate device that reports to the first PO device;

wherein, said PO devices are adapted for wireless and bi-directional intercommunication over one or more communication channels.

10. The PO device system of claim 9, wherein, said bi-directional intercommunication is accomplished by a technique selected from the group consisting of time slicing, the use of distinct frequency sets, and the use of temporarily shifted frequency sets.

11. The PO device system of claim 9, further comprising a remote control adapted for wireless communication with at least one of said PO devices.

12. The PO device system of claim 9, wherein said remote control is a fob.

13. The PO device system of claim 9, wherein at least one of said PO devices is a prosthetic socket evacuation device.

14. The PO device system of claim 9, further comprising a data transfer device to which at least one of said PO devices may wirelessly transmit data, said data transfer device including said common communications module.

15. The PO device system of claim 14, wherein said communications/control module of said data transfer device is located within a portable housing connected to a USB interface.

16. The PO device system of claim 9, wherein at least certain ones of said PO devices employ frequency hopping within a given communication time slice.

17. A method of effecting bi-directional intercommunication between multiple PO prosthetic/orthotic (PO) devices of a PO device system, comprising:

providing a plurality of PO devices in the form of multiple artificial limb components, each PO device including a common communications/control module having communication and control components, said communication and control components mounted to a single board and including at least a transceiver, a microprocessor, and an antenna;

programming said communications/control module to perform one or more functions unique to the PO device to which it is installed;

providing one or more communication channels over which said PO devices may wirelessly and bi-directionally intercommunicate; and

employing one or more communications techniques selected from the group consisting of time slicing, the use of distinct frequency sets, and the use of temporarily shifted frequency sets to ensure uninterrupted intercommunication between PO devices.

18. The method of claim 17, further comprising using a remote control to wirelessly communicate with at least one of said PO devices.

19. The method of claim 17, wherein at least one of said PO devices is a prosthetic socket evacuation device.

20. The method of claim 17, wherein at least certain ones of said PO devices further employ frequency hopping within a given communication time slice.
