Abstract

Enhanced Bluetooth and/or cellular frequency hopping radios are integrated into a hands-free wireless mobile computing and video display headset. Forms of these enhanced headsets incorporating the enhanced frequency hopping spread spectrum radio technology are of interest to military, police, fire fighters, first responders and certain commercial companies such as utility companies seeking private cellular systems seeking enhanced communication privacy.

Claims

1. A portable wireless communication headset comprising:

a wireless interface that communicates using frequency hopping spread spectrum at a physical layer according to a frequency hopping pattern specified by a commercial standard communication protocol;

a processor on-board the portable wireless communication headset enabling a user controlled adaptive frequency hopping pattern, the user controlled adaptive frequency hopping pattern being selectively operated on-demand as defined by user command; and

an input device for a user to selectively enable either the frequency hopping pattern or the adaptive frequency hopping pattern, the input device coupled to the processor in a manner communicating the user command, and the processor responsively selecting one of the frequency hopping pattern and the adaptive frequency hopping pattern according to the user command.

2. The apparatus of claim 1 wherein the adaptive frequency hopping pattern is a custom frequency hopping pattern.

3. The apparatus of claim 1 wherein the commercial standard protocol is a wireless LAN, Bluetooth or digital cellular (3G/4G/LTE/WiMax) procotol.

4. The apparatus of claim 1 wherein the headset further comprises:

a microdisplay, for displaying visual information received from a local processor;

a motion detector, for detecting physical movement of a body part of a user, and to provide a motion or gesture input; and

the local processor located in the apparatus and further comprising;

a transceiver, for receiving the motion or gesture input;

a translator, for translating the motion or gesture input to a translated command;

a display controller, for forwarding information to be displayed on the microdisplay, depending on the motion or gesture inputs.

5. The apparatus of claim 4 wherein the information to be displayed further comprises a visual or audio confirmation of the local processor having translated the motion or gesture input to the translated command.

6. The apparatus of claim 4 wherein the wireless communication interface is further for forwarding the translated command to a host processor, and for receiving a reply from the host processor.

7. The apparatus of claim 1 wherein the adaptive frequency hopping pattern is a private frequency hopping pattern.

8. The apparatus of claim 1 wherein the adaptive frequency hopping pattern is an on-demand frequency hopping pattern.

9. The apparatus of claim 3 wherein the commercial standard protocol is a digital cellular 3G protocol.

10. The apparatus of claim 3 wherein the commercial standard protocol is a digital cellular 4G protocol.

11. The apparatus of claim 3 wherein the commercial standard protocol is a digital cellular LTE protocol.

12. The apparatus of claim 3 wherein the commercial standard protocol is a digital cellular WiMax protocol.

13. A portable communication headset comprising:

a wireless interface that communicates using frequency hopping spread spectrum at a physical layer according to a frequency hopping pattern specified by a commercial standard communication protocol; and

a processor on-board the portable wireless communication headset for selectively enabling an additional private frequency hopping-pattern based on user command, in response to the user command, the processor selectively operating on-demand either the frequency hopping pattern or the additional private frequency hopping pattern.

14. The apparatus of claim 13 wherein the headset further comprises:

a microdisplay, for displaying visual information received from a local processor;

a motion detector, for detecting physical movement of a body part of a user, and to provide a motion or gesture input; and

the local processor located in the apparatus and further comprising;

a transceiver, for receiving the motion or gesture input;

a translator, for translating the motion or gesture input to a translated command;

a display controller, for forwarding information to be displayed on the microdisplay, depending on the motion or gesture inputs.
