  • Publication number: 20190291066
    Abstract: An apparatus, method and system providing for calibration and/or control of a liquid dispensing system is disclosed. The hand-held calibration auditing tool includes a flow meter (36-37) with inlets adapted for quick connection to one or more liquid inputs to a liquid dispensing system (10). A sensor (94-95) having a data output of liquid flow information for a liquid input to the dispensing system (10) is operably connected to a controller (12) to receive the liquid flow information for the liquid input. The controller (12) provides a dilution rate and other liquid flow information for a liquid product input to a dispenser.

  • Patent number: 9900696
    Abstract: An air motion transformer loudspeaker driver including a plurality of diaphragm layers having electric conductors. Each of the diaphragm layers defines a surface having at least one curved portion. The curved portions have an axis of curvature being perpendicular to the surface of the diaphragm layer at the location of the curved diaphragm portions.

  • Patent number: 5295194
    Abstract: A multi-driver, coaxially mounted loudspeaker array utilizing a high frequency bi-morph driving element (tweeter) that is preferably contained within the air-core of the voice coil former of a lower frequency loudspeaker (woofer). The outwardly extending conical edge of the high frequency device's diaphragm is annularly fixed by a compliance to the inner surface of the referenced voice coil former or to the woofer diaphragm which extends outwardly therefrom. Alternately, the bi-morph element is attached to other dynamic parts of the woofer such as the dust cap or at the rim of, or otherwise on, an extension of the former. In this mode, the bi-morph element may first be mounted to a section of a cylinder or cone which acts as a frame of the same circumference or more/less than that of the coil former. Thereafter, the frame is mounted to the end of, over or inside the coil former, or any moving part of the woofer.

  • Patent number: 5062139
    Abstract: A multi-driver, coaxially mounted loud speaker array utilizing a high frequency bi-morph driving element that is totally contained within the hollow core of the voice coil former of a lower frequency loud speaker. The outwardly radiating conical edge of the high frequency device's diaphragm is annularly fixed by a compliance to the inner surface of the referenced voice coil former or to the diaphragm which radiates outwardly therefrom and is excited by the former. A significant advancement in the art is acquired by the realization of a cavity between the situs of the bi-morph driving element and the back of the former--excited diaphragm, behind the annular compliance. This feature allows a design engineer to literally tune the response of the higher frequency loud speaker by deliberately varying the volume of the cavity.
