Abstract: A nozzle assembly including an inner tube and an outer housing. The inner tube terminates at an outlet end and defines a first flow passage. The first flow passage directs first fluid flow to the outlet end in a primary flow direction. The outer housing includes a tubular side wall and an end wall. The tubular side wall defines a central axis. The end wall defines an exit orifice and an interior guide structure. The outlet end is axially aligned with the exit orifice. A second flow passage is established between the inner tube and the outer housing. The interior guide structure is configured and arranged relative to the outlet end to direct at least a portion of a second fluid flow from the second flow passage toward the outlet end in a direction initially opposite the primary flow direction for generating mixed fluid flow.

Abstract: A system for disinfecting an enclosed area may include at least one ultraviolet (UV) light and a fogging device which may include a portable housing, an atomizing disinfectant generator carried by the portable housing, and a processor carried by the portable housing. The processor may be configured to initiate a treatment cycle during which the atomizing disinfectant generator dispenses atomized disinfectant fluid into the enclosed area, after a first time period activate the at least one UV light while the atomized disinfectant fluid is being dispensed into the enclosed area, and after a second time period later than the first time period deactivate the at least one UV light and prior to completion of the treatment cycle.

Abstract: A supply port receives supply of washing liquid. An oscillation chamber oscillates the washing liquid supplied through the supply port. A jetting section jets the washing liquid oscillated in the oscillation chamber to the outside. The jetting section includes a passage connecting the oscillation chamber and the outside. The washing liquid enters the passage from the oscillation chamber through an entrance, passing through the passage, and emitted through an exit to the outside. A jet port is provided between the entrance and the exit, having a narrower width than those of the entrance and the exit. An outer guide connects the jet port and the exit. An inner guide connects the entrance and the jet port, and configured to conduct the liquid oscillated in the oscillation chamber to the outer guide.

Abstract: An energy-saving and high-efficiency shower head capable of producing a pulsating stream includes a main body having an inlet opening, an upper cover and a cover plate connected to the underside of the main body, a water-stop mechanism, and a face plate. The cover plate is formed with a water-passing chamber and a pulsating chamber having an oblique hole. The pulsating chamber is provided with at least two diversion holes to form two outlet passages. The water-stop mechanism is composed of an impeller and a water-stop piece disposed on the impeller. The water-stop piece alternately blocks one of diversion holes when the impeller rotates to intermittently open and close the outlet passages corresponding to the diversion holes, providing a pulsating stream effect.

Abstract: The invention generally relates to methods and systems for manipulating droplet size. In certain aspects, the invention provides methods for manipulating droplet size that include forming droplets of aqueous fluid surrounded by an immiscible carrier fluid, and manipulating droplet size during the forming step by adjusting pressure exerted on the aqueous fluid or the carrier fluid.

Abstract: A fluidic chip defining an oscillator device for a spray system which provides a fan spray pattern of a fluid mixture at low temperature conditions while using standard fluid pump pressures. The fluidic chip configurations as described may provide a substantially stable exit fan angle at temperatures as low as about −10 degrees Celsius.

Abstract: An external lens washing system has an aiming fixture configured to support and constrain an external lens which is exposed to the elements and apt to become soiled with debris. A nozzle assembly is configured to be supported and aimed toward the external lens by the aiming fixture and has at least one laterally offset washing nozzle projecting from the aiming fixture to a spray washing fluid toward the external lens surface, spraying at a shallow, glancing spray aiming angle to impinge upon and wash the lens external surface. Optionally, an integrated image sensor and lens washing assembly is configured for use with a remote control method for cleaning an exterior objective lens surface and includes a sealed image sensor housing assembly including an integral, remotely controllable lens cleaning system with an optimized configuration for aiming one or more cleansing sprays from one or more laterally offset fluidic oscillators.

Abstract: A method of prepping a cylindrical inner surface of a bore using a high-frequency forced pulsed waterjet apparatus entails generating a pressurized waterjet using a high-pressure water pump, generating a high-frequency signal using a high-frequency signal generator, applying the high-frequency signal to a transducer having a microtip to cause the microtip to vibrate to thereby generate the high-frequency forced pulsed waterjet, and rotating the rotatable ultrasonic nozzle inside the bore to prep the inner cylindrical surface of the bore using the high-frequency forced pulsed waterjets exiting from the angled exit orifices of the rotatable ultrasonic nozzle.
