Abstract: Provided is a fluidic oscillator circuit for a nozzle assembly configured to generate oscillating sprays of fluid from an outlet of the nozzle assembly and to improve spray performance of fluid having low temperatures or high viscosity. In one embodiment, provided is an interaction region for a fluidic oscillator circuit that includes an apex protrusion shaped to assist with generating vortices within the interaction region. In another embodiment, provided is an interaction region for a fluidic oscillator having a power nozzle that includes at least one finger protrusion that lengthens the power nozzle to create jets of fluid in the interaction region that are less diffused to improve cold performance of the fluidic oscillator circuit.

Abstract: The present disclosure relates to a showerhead that outputs a pulsating or massaging spray. The showerhead may include an engine including a flow directing housing, a turbine, and a shutter to create the pulsating or intermittent spray. The flow directing housing may have a plurality of flow directing apertures defined around its perimeter, allowing for water to tangentially flow into the engine, rotating the turbine. As the turbine rotates, the shutter moves back and forth creating the pulsating spray.

Abstract: An assembly may include a speaker supportable for movement relative to a reference external to the speaker and a speaker housing supporting speaker components operable to produce an audio output. A sensor is operable to sense a direction of movement of the speaker during movement of the speaker relative to the reference. Control components are operable to control the speaker components based on the direction of movement of the speaker relative to the reference. When the speaker is sensed to be moving in a first direction relative to the reference, an operational characteristic of the speaker components is controlled to increase or advance during movement in the first direction. When the speaker is sensed to be moving in a second direction relative to the reference different from the first direction, the operational characteristic of the speaker components is controlled to decrease or retreat during movement in the second direction.

Abstract: A method of cavitation peening may include coupling a moveable water source to a portable nozzle, through a flexible conduit. The method may include positioning the nozzle adjacent a treatment surface and discharging a first and second stream of fluid through a first and second channel of the nozzle, with the second channel concentrically positioned around the first channel. The first stream may have a first pressure, and the second stream may have a second pressure, the first pressure being greater than the second pressure and the two streams combining to generate a cloud of cavitation bubbles.

Abstract: A multi-stage fluidic oscillating circuit and system can produce an output spray of selectively varying frequency, even though the fluid supplied to the circuit/system is maintained at a substantially constant pressure. The circuit is characterized by two successive stages, each having a power nozzle aligned around a central axis. Upstream and downstream inertance loops are included in each of the stages, with fluid from one of these loops being selectively released to affect the frequency change in the output spray. The circuit is also characterized by a splitter and optional dog ear style protrusions formed in the outlet of the circuit.

Abstract: A flow-restricted compound spray generating device 100 includes a spray face member 120B including at least one fluidic circuit oscillator defining geometry 132 including an outlet orifice 138 in the spray face member's central area configured to aim an oscillating spray 300 having a selected oscillating spray thickness distally along a spray axis 112. The spray face member 120B also includes a plurality of non-oscillating (e.g., laminar or jet) spray generating orifices 160B arrayed evenly around the spray face member's periphery to aim a plurality of non-oscillating laminar or jet sprays 302 distally along the spray axis 112 to provide a ring of high velocity streams arrayed around the central oscillating spray 300 to generate a compound spray 310 with an outflow which has a pleasing spray density with an apparent outflow thickness which is substantially equal to the spout orifice's diameter 320.

Abstract: A device for repelling pests includes a housing, a positioning mechanism to move the housing, at least three range-finding elements affixed to the housing along a common plane to detect a presence of a pest (e.g., an animate pest such as an animal, or an inanimate pest such as a drone) by obtaining a signal indicative of a location of the pest relative to the device, a projectile launcher affixed to the housing to fire one or more projectiles therefrom, and a controller electronically coupled to the range-finding elements, the positioning mechanism, and the projectile launcher. The controller may be configured to move the housing using the positioning mechanism until a strength of the signal obtained from each of the range-finding elements is substantially equal thereby indicating that the projectile launcher is directed toward the location of the pest, and to fire projectiles from the projectile launcher toward the pest.

Abstract: Methods are provided for producing an intermittent liquid jet are provided that involve delivering a liquid through a gas dynamic nozzle, which includes an inner tube carrying the liquid, an outer tube carrying a focussing sheath gas, an exit channel and an exit aperture, injecting a stream of the liquid into the exit channel, wherein the liquid is enclosed by the focussing sheath gas in the exit channel, controlling emission of the liquid from the inner tube into the exit channel to produce a periodic, linear intermittent liquid jet including spurts of linear continuous jet sections separated by liquid-free gaps, and output of the intermittent liquid jet through the exit aperture. Furthermore, methods of scattering measurements on samples in a liquid using the method of producing an intermittent liquid jet and an injector device for producing an intermittent liquid jet are described.
