Abstract: In one embodiment, a lidar system includes a wavelength-tunable light source configured to emit pulses of light, each emitted pulse of light having a particular wavelength of multiple different wavelengths. The lidar system also includes a scanner configured to scan the emitted pulses of light across a field of regard of the lidar system. The scanner includes (i) a beam deflector configured to angularly deflect each emitted pulse of light along a first scan axis according to the particular wavelength of the emitted pulse of light and (ii) a scan mirror configured to scan the emitted pulses of light along a second scan axis different from the first scan axis. The lidar system further includes a receiver configured to detect a received pulse of light that includes a portion of one of the emitted pulses of light scattered by a target located a distance from the lidar system.

Abstract: A method of generating a comprehensive image (87) of interior surfaces (78, 80) of machine components such as a gas turbine combustor basket (59) and transition duct (34) by digitally stitching together multiple photographs (82) thereof, and analyzing the comprehensive image by contouring (91, 95A-B) of colors and shadings thereon, and quantifying and tracking aspects of the contours (A, B, C) over time for indications of degradation (89) of the interior surfaces. A scope (58) may be inserted into a port (56) in the combustor with a camera (72, 74) in a rotatable end (70) of the scope for obtaining a circumferential set (84) of photos at each axial position along a length of the combustor and transition duct. A 3D surface scanning device (76) in the scope may define the geometry of the interior surface for 3D photographic modeling thereof providing a virtual walk-through inspection.

Abstract: A paint ball caddy is provided for use with competitive paint ball guns as a means for conveniently transporting paint balls for use as ammunition. The paint ball caddy has a body that accompanies the entire contents of a conventional paint ball carton, but which includes a pouring spout and a handle on the body that can be gripped to tip the paint ball caddy and pour a quantity of paint balls out of the spout in a controlled manner. The top of the paint ball caddy is provided with a large refill opening, which may be closed with a removable lid. Paint balls may be poured from the caddy into smaller, conventional paint ball canisters, or directly into the hopper of the magazine of a conventional paint ball gun.

Abstract: High speed impact line printers comprise a continuously moving type carrier, such as an endless belt or band having engraved type characters movable at constant speed parallel to a row of print hammers. A print medium such as a continuous paper web and an ink ribbon are located between the hammers and the type carrier. The hammers are uniformly spaced parallel with the type carrier to define a print line. The spacing of the hammers corresponds to the desired spacing of the printed characters when printed and generally has one print hammer for each print position. An interposer member located between the print hammers and the print paper web enables certain characters such as vertical or horizontal bars of bar code type can be printed in the region of the clearance gaps between hammers.

Abstract: A document feed device, illustrated with a copier machine, for recirculating documents through a processing station. A movable portion of the document feed device is mounted for pivoting movement to expose a lower document feed path. The movable portion contains several document moving rollers but no prime movers, gears or belts; these rolls are driven by frictional contact with each other and ultimately by contact with a set of driven rollers located in the nonmoving portion of the document feed device. The rollers comprising a document moving nip are oppositely skewed relative to the direction of document travel in order to move documents gently toward a reference edge and coefficients of friction of roller materials are chosen to insure correct document alignment.

Abstract: A moving document copier machine with a hinged cover of a recirculating semiautomatic document feed device for pivoting away from the top surface of the machine to expose the document feed path and enable the copying of a book or like object. A spine or rail means is provided along one edge of the document feed path to receive the center break of an opened book. Roll means interior to the document feed path support that portion of the book to be copied as it moves across the viewing station while other rollers, exterior to the document feed path, support that portion of the book not to be copied. A gate is provided to register the book.

Abstract: A back-lighted display sign having a protective outer face panel, a copy frame positioned behind the face panel, and a number of retaining members affixed to the rear of the copy frame to receive and retain replaceable copy inserts and color filters behind the copy frame. In one disclosed embodiment, the copy inserts include a number of transparent overlays bearing characters defined by regions of contrasting transparency.

Abstract: An electrophotographic copier machine with a roll fuser where one of the mating rolls is comprised of a thin outer shell which takes a variable taper so that a concave shape is produced under high humidity conditions and a relatively straight roller is produced under low humidity conditions. Means for changing the support at the roll ends is provided to produce the variable taper. End plugs can be moved axially inward at high humidity to provide support for the end portions of the normally concave roll and can be moved axially outwardly under low humidity such that no support is provided until the roll ends are flattened under the pressure of a mating roll.

Abstract: A copier having a stationary document glass and a scanning illumination/optics mechanism. The illumination/optics mechanism reciprocates through a linear scan motion and a reverse-direction reset motion during a copy process cycle. A moving photoconductor is connected to move the scanning mechanism in a scanning direction for a first part of the photoconductor movement, and to move the mechanism in the opposite reset direction during a second part of the photoconductor movement. Rotary-to-reciprocating harmonic motion mechanism couples the photoconductor's motion to the scanning mechanism to move the mechanism through the scan and reset motion.
