Abstract: Embodiments include methods and apparatuses for echo cancelation involving multiple audio channels and the production, sensing, or a combination thereof of multiple audio channels in conferencing systems. A conferencing apparatus with a plurality of speakers configured to generate outgoing acoustic waves responsive to a multi-channel audio signal. One or more microphones are configured to sense incoming acoustic waves from the plurality of speakers and from locally produced acoustic waves from a participant of a conference to generate one or more incoming audio signals. A processor is operably coupled to the plurality of speakers and the one or more microphones. The processor is configured to perform acoustic echo cancelation on the one or more incoming audio signals relative to at least two different channels of the multi-channel audio signal.

Abstract: A system and method for capturing an image of one or both irises. To image an iris, a person stands or moves in a target zone. A flash element provides an incoherent flash of light through an aperture. The flash is filtered to produce filtered light. The filtered light has primary wavelengths in the far red and near infrared portions of the spectrum. The filtered light is not perceived well by the human eye due to short duration, NIR color and small size. The intensity of the filtered light at the target area surpasses the intensity of all ambient light. In this manner, a person's face in the target area will always be properly illuminated, even if that person were backlit by full sunlight. An image of the person's face is taken with a camera. The image of the face is analyzed to obtain any iris pattern information.
