  • Publication number: 20170019188
    Abstract: In one embodiment, a method includes receiving ultrasound frequency sweeps in a sound receiving device. Each of the plurality of ultrasound frequency sweeps is centered on one of at least two predetermined frequencies. The method also includes converting the ultrasound frequency sweeps into an ultrasound message based on a central frequency of each of the ultrasound frequency sweeps received, and placing the ultrasound message into a receive buffer. Then at least a network address is extracted from the ultrasound message, and the network address is used to establish a communication session over a data network with a telecommunications device.

  • Publication number: 20130050398
    Abstract: A method is provided in one example embodiment and can include displaying a first image signal on a screen and capturing an object in front of the screen in a captured object/image signal. The method may further include generating an object signal by removing the first image signal from the object/image signal, where the object signal is a representation of the object captured in front of the screen.

  • Patent number: 8170256
    Abstract: A microphone assembly for desktop communication systems utilizes a directional microphones in a desktop conferencing system without exposing the microphone to unfavorable mechanical or acoustic influence. The microphones is built into the front portion of the base of the system, in a mechanically controlled and robust way. The microphone assembly maximizes microphone sensitivity in the direction of a near end user while simultaneously minimizing microphone sensitivity in the direction of the loudspeaker.

  • Patent number: 7856112
    Abstract: The present invention discloses an inventive microphone assembly for desktop communication systems. It utilises the advantages of placing the microphone in a desktop conferencing system as close as possible to the tabletop surface, without exposing the microphone for unfavourable mechanical or acoustic influence. This is achieved by building it into the footing in front of system, in a mechanically controlled and robust way. In this way, the high frequency response can be controlled to optimise sound quality, and at the same time the microphone assembly can be configured as a flexible unit that easily can be re-used in other systems.
