    摘要: An improved ultrasound transducer assembly, e.g. a thickness-mode transducer assembly includes a plurality of elements comprising piezoelectric material, and a backing material disposed adjacent to a back surface of the plurality of elements. The piezoelectric material and backing material define at least a portion of a side surface, wherein an electrically conductive material is disposed upon and in contact with at least a portion of the side surface. The elements may comprise one or a plurality of front electrodes, and one or a plurality of back electrodes, wherein the front electrode(s) is electrically interconnected to the electrically conductive material disposed on the side surface portion. In a mass processing method, a plurality of thickness-mode ultrasound probe transducer assemblies may be produced, wherein a plurality of interconnected transducer subassemblies comprising a mass backing are processed in tandem.

    摘要: A system and method for providing a substantially constant volume exhaust or ventilation air terminal system is shown for controlling exhaust and/or return airflow rates in a system having a central fan or ventilator. The system and method permits zone-by-zone or area-by-area airflow regulation or control in non-demand areas in response to a demand or call for ventilation in demand areas. In one embodiment, the system employs at least one constant airflow controller or regulator situated in a damper. Another embodiment shows a combination of a first regulator constant airflow controller or regulator situated or mounted on a damper with a second constant airflow controller or regulator situated in a duct associated with the damper. In still another embodiment, a constant airflow controller or regulator is provided in a duct, and used in combination with a solid damper.
