Abstract: A method for using a loudspeaker array that is housed in a loudspeaker cabinet to present audio content to a listener in a room includes receiving (1) an audio channel that includes audio content and (2) acoustical characteristics of the room. The method also produces (1) a first beamformer input signal from the audio channel and (2) a second beamformer input signal and a third beamformer input signal by decorrelating the audio channel and adjusting the audio channel in accordance with the acoustical characteristics of the room. The second and third beamformer input signals are different de-correlated versions of the audio channel. The method also generates driver signals from the first, second, and third beamformer input signals to drive the loudspeaker array to produce a main beam, a first ambient beam, and a second ambient beam, respectively. Other embodiments are also described and claimed.

Abstract: An N-alkylpolyhydroxyamine salt of an n-6 or n-3 essential fatty acid (EFA) that is beyond the 6-desaturation step, or of any polyunsaturated fatty acid, other than those belonging to the n-6 and n-3 series, having 16 to 26 carbon atoms and up to six double bonds, the double bonds being in the cis or trans configuration, the salt being formed with the fatty acid either as such or in the form of a covalent derivative, through the carboxyl group, of a bifunctional compound itself having a free acid function.

Abstract: A marker system comprising a marker light and a marker; the marker light including a base plate having a plurality of bolt holes and a plurality of mounting bolts having threaded shanks extending through the bolt holes for securing the base plate to a support surface including threaded holes for receiving the threaded shanks of the mounting bolts; and a marker including a resiliently flexible marker rod having a height greater than the marker light and an attachment fitting at the lower end of the marker rod. The attachment fitting has a lower threaded shank portion for extending through one of the bolt holes in the base plate normally occupied by one of the mounting bolts, an intermediate head portion, and an upper portion to which the marker rod is attached.

Abstract: Multiple hydrocyclone apparatus including plural loop-like arrays of hydrocyclones is provided with a walkway space inside the innermost array. A passageway is provided to permit entry of an operator into the walkway space for inspection and repair of the inner hydrocyclones. The apparatus may be made in an elongated form to fit available mounting space. Baffles may be provided within the feed plenum for directing the flow of feed stock. Appropriate devices may be provided for bleeding minor portions of the feed stock from the feed plenum to maintain the velocity of the stock flowing within the plenum.
