Filed:

May 6, 1999

Appl. No.:

09/306225

Inventors:

Veijo Matias Tuoriniemi - New York NY 10003-3629
Joseph Michael Allison - Euclid OH 44117

International Classification:

H04B 138

US Classification:

455575, 455 95

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.

Abstract:

A portable communication and audio system includes a radio telephone for receiving a first audio signal and transmitting a corresponding first radio signal through a transmitter to another location, and for receiving a second radio signal through a receiver and converting it to a second audio signal. An audio device provides a third audio signal. A microphone receives the first audio signal. A headset with first and second speakers is provided for selectively listening to the second or the third audio signal. A user-operated switch selectively disables the first speaker in a first state or the microphone in a second state. A state-indicating apparatus produces a signal indicating the state of the user-operated switch. A control apparatus, responsive to the state-indicating apparatus, enables telephone usage by connecting the microphone to the transmitter and connecting the second speaker to the receiver when the user-operated switch is in the first state, and connects the first and second speakers to receive the third audio signal when the user-operated switch is in the second state. The system preferably includes a pivotable boom depending from the headset, with the microphone being located on the boom.
