20120294121 | Transducer for Phased Array Acoustic Systems - A transducer includes a base, a horn, and a central element. The horn includes a first end coupled to the base and a second end extending from the base and having a perimeter that defines a substantially planar face of the transducer, the horn defining a horn length along a horn surface between the first end and the second end of the horn. The central element includes a first end coupled to the base and a second end extending from the base along a longitudinal axis of the horn, the central element defining a central element length along a central element surface between the first end and the second end of the central element, the central element length being substantially equal to the horn length. | 11-22-2012 |
20120218866 | Housings for Phased Array Monostatic Sodar Systems - A housing for a phased array monostatic sodar system with a transducer array that emits and receives multiple generally conical main beams of sound along different primary axes. The housing includes one or more upwardly-directed sidewalls that define a volume between them that is open to the atmosphere at the top, to emit and receive the beams, and an upper lip at the top of at least one wall, defining a curved perimeter at the top of at least some of the volume that closely conforms to the shape of at least one main beam at the location of the lip. | 08-30-2012 |
20110273962 | Transducer Array Arrangement and Operation for Sodar Applications - An array of transducers for a sodar system, and the operation of the array in a monostatic sodar system. The array is made up of a number of individual sound transducers. Each transducer emits sound into the atmosphere and senses emitted sound that has been reflected by the atmosphere. The transducers have a generally circular cross-sectional shape. The transducers are arranged in a generally planar, generally hexagonal grid packing arrangement. | 11-10-2011 |
