Method And System For Automatic Audio Accessory Use Position Detection And Audio Adjustment

View page
US Patent:
8271037, Sep 18, 2012
Filed:
Feb 28, 2007
Appl. No.:
11/679877
Inventors:
Charles B. Harmke - Port Barrington IL, US
Assignee:
Motorola Solutions, Inc. - Schaumburg IL
International Classification:
H04B 1/38
H04M 1/00
US Classification:
455557, 4555501
Abstract:
A method () and system () of sensing the position of an audio accessory () having at least a microphone () can include a sensor ( and/or ) for detecting one among a plurality of positions of the audio accessory and a processor () programmed to equalize an audio input from the microphone based on which one among the plurality of positions was detected. The sensor can be a thermal sensor, an optical sensor, or a proximity sensor. The audio accessory can be a remote speaker/microphone accessory. Among the plurality of positions that can be detected can include a Mouth Reference Point (MRP) or a Shoulder position. The processor can be further programmed to automatically equalize () a microphone input audio based on one of the plurality of positions detected. The system can also be programmed to automatically equalize () when a push-to-talk activation occurs at the audio accessory.

Method And Apparatus For Operating Accessory Interface Functions Over A Single Signal

US Patent:
20140004807, Jan 2, 2014
Filed:
Jun 29, 2012
Appl. No.:
13/538561
Inventors:
Charles B. Harmke - Huntley IL, US
Assignee:
MOTOROLA SOLUTIONS, INC. - SCHAUMBURG IL
International Classification:
H04B 1/38
US Classification:
455 902
Abstract:
An interface () is provided between an accessory () and a radio () to enable three functions over a single signal line () thereby minimizing pin count in a connector (). The functions of accessory detect, one-wire memory and accessory PTT press are controlled over the single signal line () through the use of two comparators () and two voltage dividers ()

Communication Device Providing Half-Duplex And Pseudo Full-Duplex Operation Using Push-To-Talk Switch

View page
US Patent:
20190387368, Dec 19, 2019
Filed:
Jun 14, 2018
Appl. No.:
16/008348
Inventors:
- Chicago IL, US
CHARLES B. HARMKE - HUNTLEY IL, US
International Classification:
H04W 4/10
H04W 76/45
H04M 9/08
H04M 1/725
H04L 5/14
H04W 88/02
Abstract:
A portable communication device provides a pseudo full-duplex communication mode by unmuting a microphone, enabling acoustic echo cancellation (AEC) and decreasing speaker volume when a push-to-talk (PTT) button is pressed, and by muting the microphone during release of the PTT button.

Validating The Operation Of A Transducer And An Audio Signal Path

View page
US Patent:
20190349697, Nov 14, 2019
Filed:
May 11, 2018
Appl. No.:
15/977150
Inventors:
- Chicago IL, US
Charles B. Harmke - Huntley IL, US
Ellis A. Pinder - Davie FL, US
International Classification:
H04R 29/00
G08B 21/18
Abstract:
Systems and methods for validating the operation of a transducer and an audio signal path to the transducer. An example method includes switching, with an audio switch, the audio signal path between an audio power amplifier and an analog-to-digital converter. The method includes routing an audio signal received from the transducer to the analog-to-digital converter when the audio power amplifier is not enabled. The method includes, upon receiving a button signal, processing, with an electronic processor, a digital version of the audio signal received from the analog-to-digital converter to generate a sample. The method includes comparing the sample to a reference audio sample. The method includes generating an alert when the sample does not match the reference audio sample.

Method And Apparatus For Providing Expanded Interface Operation Between A Portable Communication Device And An Accessory

View page
US Patent:
20180145745, May 24, 2018
Filed:
Nov 18, 2016
Appl. No.:
15/355081
Inventors:
- CHICAGO IL, US
CHARLES B. HARMKE - HUNTLEY IL, US
ELLIS A PINDER - DAVIE FL, US
International Classification:
H04B 7/26
G06F 13/40
G06F 13/36
G06F 13/42
Abstract:
Improved connectivity between a portable communication device and an accessory is provided through the configuration of a USB type interface. Independent control of a mission-critical subsystem and auxiliary subsystems allow for mission-critical audio and push-to-talk (PTT) to be maintained even in the event of a fault condition within the system. The configurability aspect of the interface allows for additional mission-critical input features to be configured into independent mission-critical subsystems.
