  • Patent number: 11461683
    Abstract: Methods, apparatuses and systems directed to pattern learning, recognition, and metrology. In some particular implementations, the invention provides a flexible pattern recognition platform including pattern recognition engines that can be dynamically adjusted to implement specific pattern recognition configurations for individual pattern recognition applications. In certain implementations, the present invention provides for methods and systems suitable for analyzing and recognizing patterns in biological signals such as multi-electrode array waveform data. In other implementations, the present invention also provides for a partition configuration where knowledge elements can be grouped and pattern recognition operations can be individually configured and arranged to allow for multi-level pattern recognition schemes. In other implementations, the present invention provides methods and systems for dynamic learning of patterns in supervised and unsupervised manners.

  • Patent number: 5082017
    Abstract: A ball cock for a flush tank having a valve chamber connected with a discharge chamber. A float operated piston valve is mounted in the valve chamber to control water flow to the discharge chamber. A hush tube connected to the discharge chamber feeds the water to the bottom of the flush tank. A combined volume control and anti-siphon valve is mounted in the discharge chamber between the inlet and hush tube to regulate the rate of flow and to act as a vacuum break under conditions of negative pressure in the water supply line.

  • Patent number: 4479736
    Abstract: A replaceable handle assembly for coupling a handle to a valve stem comprising a connector for gripping the spline of a valve stem, a base member positioned over the connector and nonrotatably engaging the connector through a rectangular-shaped fitting, and a screw securing the base and connector to a valve stem. A post fits into an upwardly-opening recess in the base through a rectangular fitting and a small set screw secures the post to the base. A handle threads onto the post above the set screw to at least partially conceal the set screw.

  • Patent number: 4272022
    Abstract: A showerhead which provides for a reduced flow volume through the showerhead includes a replaceable decorative cover. The showerhead has a skirt housing (24) which is swivelably mounted on a ball joint (10) connected to a water supply pipe. A generally cylindrical spray director (32) is welded to the skirt member (24) to provide a spray pattern emitting from the showerhead. An orifice plate (44) which reduces the flow volume and a face plate (50) which defines a spray pattern are disposed within the spray director (32) downstream of the ball joint (10). The face plate (50) is axially adjustable in order to vary the spray pattern as well as provide for a self-flushing showerhead. The decorative cover includes an annular shell (58) coaxially disposed about the spray director (32) and an end plate (64) which is snap-fit into the outlet of the spray director. In this way, decorative covers of different styles can be used with the same functional assemblies.
