Abstract: Adjusting sound using biometrical information is provided by measuring a response of a human's ear to a test signal, comparing the measured response with a target response, obtaining deviations between the measured response and the target response, and adjusting sound using the obtained deviations.

Abstract: The invention relates to mobile audio playback devices and methods of its operation for enhanced music and sound experience for mobile devices. To provide stereo and surround sound, the present invention provides an audio playback device with a receiving means for receiving multi-channel audio data, obtaining means connected to the receiving means, for obtaining first channel audio data from the multi-channel audio data for playback on the audio playback device, and playback means having at least one loudspeaker, and being connected to the obtaining means for outputting the first channel audio data. The other not selected audio channels or all received audio data may be transferred to other terminals for playback or may be discarded.

Abstract: An IP telephony network is made connectable to an existing PBX or other equipment connected to a PSTN via an IP telephone gateway/shuttle and relay and a remote hook flash allows a user with a remote IP terminal or POTS phone access to the features available on the existing PBX or other equipment.

Abstract: A mist eliminator device, particularly well suited for use in a wet scrubber apparatus, has a plurality of parallel spaced apart chevron shaped baffle members transversely disposed in a peripheral frame to define a plurality of parallel correspondingly chevron shaped gas flow passages each having an inlet and outlet accommodating the flow of gas through the mist eliminator. Each passage includes an upstream branch disposed proximate the gas inlet and a downstream branch disposed proximate the gas outlet. The upstream branch of each gas flow passage is obliquely oriented to the plane of the peripheral frame and the downstream branch is oriented perpendicularly to the same plane. A mist trapping flange projects into each upstream branch of the gas flow passages and another mist trapping flange projects into each downstream branch of the gas flow passages.
