Abstract: A method and apparatus for inspecting a surface of an object. Data from measuring the surface of the object is obtained to form surface data for the object. A range of frequencies for features on the object is selected based on a range of distances between adjacent peaks for the features. The features are formed by a tool moving along a number of paths. Desired surface data for the features is obtained from the surface data using the range of frequencies selected. A determination is made as to whether the desired surface data for the features meets a policy specifying a desired surface for the object. In response to an absence of a determination that the desired surface data for the features meets the policy, the object is reworked.

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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method and apparatus for diminishing display transients and jitter. The method and system disclosed utilizes prior illumination and position histories in displaying and illuminating representations, and elements comprising the representations, on the display. Recognizing repeated representations, finding their prior and current positions, and determining if the difference in position is over a threshold value, diminishes the jitter by displaying the representation in the new position if over the threshold value, or, if it is not over the threshold value, then displaying it in the prior location. The illumination of an element at an intensity, which is based on prior illuminations and/or intensities of the element, diminishes the transients by avoiding flashing or flicker of transient illuminations.

Abstract: 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.

Abstract: 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.
