Abstract:
An audio system has a base station and a plurality of wireless microphones that are associated with the base station. The wireless microphones operate to capture acoustic audio information and to transmit this audio information to the base station. Each of the wireless microphones operate to detect whether or not they are connected to an external voltage source. If any of the plurality of the wireless microphones determines that they are not connected to an external voltage source, then it is controlled to transition to a first operational state. Or if a wireless microphone determines that it is connected to an external voltage source, and depending upon the voltage level detected, the microphone can transition to either a second or a third operational state.
Abstract:
One or more audio conferencing systems are connected to a local network, and each conferencing system is comprised of a plurality of wireless microphones in communication with a plurality of antennas deployed in an array configuration. Each of the antennas comprising one of the audio conferencing systems is in direct communication with a base station and in indirect communication with a server which runs a centralized digital signal processing functionality. The digital signal processing functionality operates on audio information received from one or more far-end audio sources and from each of the one or more audio conferencing system.
Abstract:
An audio system is configured to support a number of wireless microphones, and each of the wireless microphones has one or more touch sensitive mute switches and a touch sensitive mute guard band switch. The mute guard band switch is connect to an electrically conductive surface that is proximate to a microphone peripheral surface that a user is likely to touch when they move the microphone. Logical instructions running in conjunction with a DSP associated with the microphone cause the audio system to override any mute commands it receives from any of the mute switches during the time that the guard band switch is activated.
Abstract:
An audio system has a base station, a speaker and one or more wireless microphones. The audio system operates to receive audio information from both a far-end audio source and a near-end audio source and to process the audio information for transmission to a far-end audio system. The wireless microphones have an electrically conductive element connected to a touch sensitive switch, and the electrically conductive element is proximate to an outer perimeter surface of the microphones. When the outer perimeter surface of the microphone is touched, the switch is activated which sends a microphone handling signal to the base station. The base station uses the microphone handling signal to control an operational characteristic of an audio signal processing function running on the base station.

Abstract:
A bus arbitration algorithm using round robin and variable packet counts. In addition, each node is assigned a maximum packet size which can be adjusted by the operating system. The round robin determines which node will be granted the bus based on priority on a serial wrap-around list. The packet count is one factor in determining how long the node granted the bus may use it. The maximum packet size is a second factor in determining the permitted duration on the bus.
