Abstract:
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.

Abstract:
In a wide area communications network such as the Internet, a public server and an associated database store and make available to a private server personal information relating to an individuals emotional or some other mental or physical state. The private server includes functionality to interpret the personal information it receives or gathers from the public server in order to identify at least one reaction instruction which can be used by a multimedia communications device to convey to a user the state of an individual by generating a human perceivable reaction which can be playing multimedia content in combination with movement if the multimedia communications device is a robot.
Abstract:
A remote control device able to connect to a communications network generates robot control messages are used for the remote control of a robot also able to be connected to the communications network. The remote control device creates a robot control file and an indirect reference to the robot control file which a user can select for inclusion in a robot control message. Once selected, the indirect reference to a robot control file causes the indirectly referenced robot control file to be included in a message generated by the remote control device. The remote control device establishes a communications link with the communications network, and sends the message, with the robot control file, to the robot also connected to the communications network. The robot receives the robot control message and performs at least one action according to the instruction included in the robot control message.
