Headset control system for operating a microcontroller based device
First Claim
1. A headset control system for operating a microcontroller based device comprising;
- a) a microphone;
b) a first and a second speaker;
c) a user operated switch for selectively activating said microphone in a first state or deactivating said microphone in a second state;
d) a resiliently biased momentary switching means for creating patterns of momentary switching from a rest position to at least one depressed position and back;
e) a switch detector comprising plurality of comparators to implement threshold logic with more than two logic levels, producing a signal indicating the respective states of said user operated switch and said momentary switching means; and
f) a control means responsive to said switch detector including a means to differentiate between different switching patterns of said momentary switching means for initiating respective function as a function of a pattern of momentary switching and state of said user-operated switch and current operational mode.

Abstract
A headset control system for operating a microcontroller based device includes a microphone, a first and a second speaker, and a user operated switch. The switch selectively disables said first speaker in a first state or said microphone in a second state. A momentary switch creates patterns of momentary switching from one of a first, a second and a third state to at least one other state and back. A switch detector comprises a plurality of comparators to implement threshold logic and produces a signal indicating the respective states of said user-operated switch and said momentary switching means. A microcontroller responsive to said switch detector includes a means to differentiate between different switching patterns of said momentary switching means and initiates respective function as a function of a pattern of momentary switching and state of said user-operated switch and current operational mode.

11. A headset system of claim 10 wherein said voice command detect circuit is activated for predetermined period of time which starts when said user operated switch is connected to said microphone by positioning said boom in front of the mouth position.
-
12. A method of operating said headset system of claim 10 comprising steps of:
-
a) connecting said further user operated switch so as to be in a voice command state;
b) detecting the connection of said state;
c) activating said voice command detect circuit;
d) giving a voice command through a microphone;
e) releasing said further user operated switch to end said voice command;
f) processing said voice command by said voice command detect circuit;
g) executing said command.
-
-
13. A method as defined by claim 12 wherein said voice command detect circuit activating user operated switch is released before giving said voice command and the end of said voice command is detected by application when a said voice command speech signal is not present.
-
14. A method as defined by claim 12 wherein said voice command detect circuit is activated for a period of time which starts by connecting and activating said microphone and the ends when said voice command speech signal is not present.
-
15. The method as defined by claim 12 further comprising ready signal through a speaker for user to start a command after activation of said voice command detect circuit.
-
16. The method as defined by claim 12 further comprising a designated signal through a speaker indicating processing of said voice.
-
17. The method as defined by claim 12 further comprising a feed-back, giving a designated signal through a speaker indicating detection of a voice command or alternatively a signal indicating rejection of said voice command.
