A water delivery device that includes a body having a cold water inlet, a hot water inlet, and an outlet; a mixing valve in the body, and a touchscreen user interface on a surface of the body. The mixing valve includes a housing having a mixing chamber that is fluidly connected to the outlet, a first flow control valve moveably disposed in the housing to control a cold water flow from the cold water inlet to the mixing chamber, and a second flow control valve moveably disposed in the housing to control a hot water flow from the hot water inlet to the mixing chamber. The touchscreen user interface allows a user to control a temperature and/or a flow rate of water from the outlet by controlling the first and second flow control valves.

METHOD AND SYSTEM FOR FLUID FLOW RATE MEASUREMENT
20190368909 · 2019-12-05 · ·

A fluid flow meter system for monitoring fluid flow through a lumen includes a first ultrasonic transducer configured to transmit one or more versions of a transmit (TX) signal through a fluid flowing within the lumen, and a second ultrasonic transducer configured to receive one or more respective receive (RX) signals. The fluid flow meter system includes an analog-to-digital converter (ADC) configured to sample, at a first frequency, the one or more RX ultrasonic signals and a processor configured to generate a fine resolution signal based on the one or more RX ultrasonic signals. The fine resolution signal is associated with a second sampling rate higher than the first sampling rate. The processor is also configured to compute a cross-correlation signal indicative of cross-correlation between the fine resolution signal and a waveform and determine an estimated fluid flow parameter based on the computed cross-correlation signal.

Hot Tap System and Method for Coated Ductwork
20190368662 · 2019-12-05 ·

Systems, apparatus and methods for hot tapping into pressurized, coated duct systems for transporting corrosive substances are disclosed. A branch line may be installed in such systems without shutting down or depressurizing the system using the disclosed systems, apparatus and methods without compromising the system coating or resistance to corrosion from the transported substances. Cut edges created when ductwork is cut to install a branch line are captured and sealed between two gaskets, avoiding the need for recoating with difficult to apply corrosive protection materials such as fluoropolymer coatings.
