A method for operating a display having a plurality of pixel elements includes applying a transition voltage to the plurality of pixel elements, applying a first paint voltage to one pixel element of the plurality pixel elements, waiting a predetermined time period, illuminating the one pixel element, applying the transition voltage to the plurality of pixel elements, applying a second paint voltage to the one pixel element elements, waiting the predetermined time period, and illuminating the one pixel element. The transition voltage is different from the first paint voltage applied to the one pixel element.

A spray nozzle assembly is provided. The spray nozzle assembly includes a nozzle body having a liquid passage that terminates in a nozzle body orifice. The spray nozzle assembly includes an impingement element having an impingement surface spaced from the nozzle body orifice. One or more air outlet orifices are disposed upstream of the impingement surface and oriented to discharge a substantially tubular curtain of air around the nozzle body orifice. An air cap defines a chamber extending around and downstream of the impingement surface. The air cap has a plurality of discharge orifices. At least one of the discharge orifices in the air cap has an associated nipple that is integrally connected to the air cap and extends the discharge orifice outwardly away from an outer face of the air cap.

An internal mix spray nozzle assembly adapted for operation with lesser pressurized air requirements. The spray nozzle assembly includes a liquid passage for directing a liquid flow stream against an impingement pin, and an air guide is provided for forming an annular pressurized air passage about the liquid flow stream for striking and atomizing a laterally spreading dispersion of liquid from the impingement surface. For enhancing liquid atomization, the air guide defines a relatively narrow width air flow opening for substantially accelerating and increasing the pressure of the atomizing air stream, and the impingement pin is formed with a relatively large primary impinging surface and a parallel downstream secondary impingement surface that facilitates further liquid particle breakdown and prevents the accumulation of liquids about the bottom of the impingement pin.

A baby or infant pacifier is disclosed with a sound activated locator annunciator. Comprised of a nipple and associated components utilized on conventional pacifiers, the disclosed apparatus also utilizes a microphone and associated electronic circuitry to monitor for distinctive sound waveforms, such as the clapping of hands, that would normally be minimally found in an infant's or baby's immediate environment. When such a distinctive waveform is detected by the use of fuzzy logic, a speaker emits an audible locator signal, such as a musical tune or sound, for a predetermined time period to allow for location of the apparatus. It is intended that this audible locator signal will aid the care provider of the infant or baby in locating the pacifier when lost.

A modular automatic spray gun manifold is provided. The manifold includes a plurality of spray gun modules arranged in an array in laterally spaced relation from each other. A junction element is arranged at an upstream end of the manifold for introducing fluid into the manifold. A first support assembly is arranged between the junction element and a first spray gun module in the spray gun module array for supporting the first spray gun module relative to the junction element. The first support assembly includes a plurality of fluid conduits for supplying fluid to the first spray gun module. One or more second support assemblies with one second support assembly are arranged between each adjacent pair of spray gun modules in the array of spray gun modules for supporting the adjacent pair of spray gun modules relative to each other. Each second support assembly includes a plurality of fluid conduits for communicating fluid between the adjacent spray gun modules such that fluid introduced into the manifold through the junction element is communicated to each spray gun module. The first support assembly and each second support assembly include an interior space through which their respective plurality of fluid conduits extend and a heat transfer fluid inlet for communicating a hot heat transfer fluid into the interior space of the respective support assembly.

A display system includes a wristwatch-sized device that a user, such as a soldier on a battlefield, can wear, a data receiver, and a small video display. The device can receive data, such as video or still digital imagery captured by an unmanned aerial vehicle (UAV) in flight or unmanned ground vehicle, and display it in real-time for the user to view.

A sand trap rake and storage apparatus, wherein a tubular storage compartment is sized to receive the sand trap rake therein. The tubular storage compartment is buried in the ground near a sand trap, so that the open top of the storage unit is above ground. A cover secures the sand trap rake in the tubular storage compartment. A compression spring pushes the rake above the top portion of the tubular storage unit for ease of access. The sand trap rake includes a head pivotally attached to the handle. A hand knob tightens the head against the handle in a first operating position perpendicular to the handle, and the hand knob is loosened to position the head in a second storage position parallel to the handle.

A modular spray gun assembly is provided. The modular spray gun assembly includes a spray gun body, a spray nozzle module and a plurality of control modules. The spray nozzle module is releaseably attachable to a downstream end of the nozzle body with a first retainer that engages a portion of the downstream end of the spray gun body. The plurality of control modules are interchangeably mountable on an upstream end of the spray gun body. A portion of each control module is receivable in a counterbore in the upstream end of the spray gun body. Each control module is releaseably attachable to the spray gun body with a second retainer that engages a portion of the upstream end of the spray gun body.

A lance-type spraying assembly for directing a reducing agent into a combustion zone or discharging combustion gases for Nox emission control. The spraying assembly including a lance body having an inlet end and a downstream end and a spray nozzle arranged at the downstream end of the lance body. The lance body includes an air passage for connection to an air supply, a liquid reducing agent supply passage for connection to a liquid reducing agent supply and a liquid reducing agent return passage. The liquid reducing agent supply passage communicates with the spray nozzle. The liquid reducing agent return passage communicates with the liquid reducing agent supply passage near the downstream end of the lance body for recirculating a portion of the liquid reducing agent and extends near the liquid reducing agent supply passage along at least a portion of the length thereof in order to help cool the liquid reducing agent therein. The liquid reducing agent return passage is sealed against the spray nozzle. The air passage extends near at least a portion of the liquid reducing agent supply passage in order to help cool the liquid reducing agent therein.

A spray device comprising a body having a liquid discharge passage and a spray nozzle assembly affixed to the body is provided. The spray nozzle assembly includes a liquid spray tip for directing liquid from the liquid passage in the body into a predetermined spray pattern and an atomizing fluid cap. The liquid spray tip includes a forwardly extending nose portion that defines a liquid discharge orifice. The nose extends through a central opening in the air cap thereby defining an annular atomizing fluid discharge orifice that communicates with an atomizing fluid inlet. The nose extends in a downstream direction past the central opening in the air cap such that the liquid discharge orifice is arranged at least approximately 2 mm. downstream of the annular atomizing fluid discharge orifice.
