Abstract: A fluidic nozzle of the scanner type has its outlet spray pattern skewed from its chamber axis (A) by an amount determined by the asymmetry of its outlet orifice (23, 33) about that axis. A spray assembly (70, 90) of such nozzles, such as a showerhead, can be designed using nozzles with selected pattern skew angles to achieve desired spray coverage. Indexing tabs (97) and slots (96) are used to angularly position the nozzles in the showerhead. A portion of each nozzle may be formed with the showerhead faceplate (71) as an integral piece.

Abstract: A computing system is described that includes user interface components configured to receive typed user input; and one or more processors. The one or more processors are configured to: receive, by a computing system and at a first time, a first portion of text typed by a user in an electronic message being edited; predict, based on the first portion of text, a first candidate portion of text to follow the first portion of text; output, for display, the predicted first candidate portion of text for optional selection to append to the first portion of text; determine, at a second time that is after the first time, that the electronic message is directed to a sensitive topic; and responsive to determining that the electronic message is directed to a sensitive topic, refrain from outputting subsequent candidate portions of text for optional selection to append to text in the electronic message.

Abstract: A fluidic scanner nozzle comprising an interaction chamber defined between an upstream end and a downstream end with a longitudinal chamber axis. The upstream end having an inlet opening for receiving and delivering pressurized fluid into said interaction chamber along said chamber axis. The downstream end having an outlet orifice for issuing a generally conical outlet spray of liquid droplets from said chamber into ambient environment and an axial gap positioned between said upstream end and said downstream end. The upstream and downstream ends may define inner cavities having a hemisphere shape. The axial gap may define a cylindrical sidewall segment aligned between an upper hemisphere shaped inner cavity and a lower hemisphere shaped inner cavity. The axial gap includes a selected axial length and an inside diameter that may be either a continuous axial gap or a stepped axial gap.

Abstract: A conformal, cup-shaped fluidic nozzle engineered to generate an oscillating spray is configured as a (e.g., 100, 400, 600 or 700). Preferably, the fluidic circuit's oscillation inducing geometry 710 is molded directly into the cup's interior wall surfaces and the one-piece fluidic cup may then fitted into an actuator (e.g., 340). The fluidic cup (e.g., 100, 400, 600 or 700) conforms to the actuator stem used in typical aerosol sprayers and trigger sprayers and so replaces the prior art “swirl cup” 70 that goes over the actuator stem (e.g., 320), With the fluidic cup (e.g., 100, 400, 600 or 700) and method of the present invention, vendors of liquid products and fluids sold in commercial aerosol sprayers 20 and trigger sprayers 800 can now provide very specifically tailored or customized sprays.

Abstract: A clog resistant in-line vortex emitter and drip irrigation assembly and method uses a double-sided circuit and a series of vortex chambers of optimized dimensions to create a pressure drop with large dimensions and good clog resistance. The vortex chamber 100 also al lows for a lower exponent than traditional circuits. This gives a pressure regulating property to the no-moving-parts circuit. The vortex emitter allows for some pressure regulation without sacrificing recyclability or requiring moving parts. The vortex circuit of the present disclosure is optimized for an emitter efficiency Ef value wherein Ef=(k/Ackt)*Amin such that k is a unitless head loss coefficient, Ackt is the area of the circuit, and Amin is the minimum cross sectional area of the circuit. A higher k per a given area with larger dimensions allows for a smaller part with a lower chance of clogging.

Abstract: A new scanner fluidic oscillator is used in an economically manufactured fluidic showerhead or nozzle assembly 50, 198, 250, 400 which aims oscillating sprays from multiple scanner fluidics to spread water uniformly over a preselected coverage area. The scanner fluidics and showerhead of the present invention provide a pleasing spray pattern, droplet size, droplet velocity, and temperature uniformity at very low flow rates (i.e., 2 gpm or less) for showering. The scanner fluidics are provided in a plurality of distinct configurations for generating individually tailored scanning sprays having a selected scanning spray characteristics. The showerhead's front plate (e.g., 56, 200, 270, 454) is configured to support and aim the fluidic oscillators, optionally with indexing slots 802 configured to receive corresponding angular indexing tabs 800 on the fluidic oscillator inserts to orient and aim the spray from each fluidic oscillator (e.g., 172, 220,282, 530).

A nozzle or rain can style showerhead assembly includes a water chamber or manifold which receives water via a central inlet fitting. Water entering the water chamber or manifold flows turbulently into and through the manifold and is expelled under pressure through a plurality of nozzles which are configured as specially adapted fluidic inserts.

The controller may change the selected energy source as required, based on factors such as cost, engine maintenance and testing and/or imminent need of the engine.
