A telepresence device comprising: a body; a camera apparatus; a first microphone; a loudspeaker; a transceiver receiving port, the transceiver receiving port operable to connect a detachable transceiver to the body; and a processor coupled to the camera apparatus, the first microphone, the loudspeaker, and the transceiver receiving port, the processor operable to communicate with an electronic communications device, wherein the transceiver receiving port is configured to couple the detachable transceiver to the processor when the detachable transceiver is connected to the body at the transceiver receiving port to enable the telepresence device to wirelessly communicate with a headset.

Telepresence system with advanced wireless operations

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.

Video conferencing apparatus

A wireless audio conferencing system has one base station and a number of portable parts each of which is able to establish a communication link with the base station. The base station is controlled to initiate and to terminate communication sessions with other communication devices over a communications network such as a LAN or a WAN, and the base station includes a DSP the implements a digital radio and system application functionality that monitors and stores certain operational state characteristics associated with the portable parts. The base station uses the stored operational state characteristics associated with each portable part to determine whether, at the end of a communication session, a portable part is connected to a charging tray or not, and if not, the base station operates to transmit a warning message indicating that a portable part is not being charged.

Generating a warning message if a portable part associated with a wireless audio conferencing system is not charging

A digital audio conferencing system has a fixed base station that is in communication with a far end (R.E.) system over a communication network. The base station is associated with a wireless loudspeaker and one or more wireless microphones. The base station operates to receive F.E. audio signals to be played by the wireless loudspeaker, and it operates to remove acoustic echo picked up by the wireless microphones. A first clock controlling F.E. audio signal sampling at the base station, and a second clock controlling audio signal sampling and at a wireless microphone are synchronized to one master, reference clock that controls the operation of the base station. Acoustic echo included in an audio signal picked up by a wireless microphone is removed by AEC functionality running in the base station.

Synchronizing audio signal sampling in a wireless, digital audio conferencing system

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.

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.

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.
