The invention is a bladder formed of multiple layers of barrier film to provide multiple pressurized layers of cushioning fluid or gas when the bladder is filled. The sidewalls of the bladder can be constructed with an inverted seam construction to eliminate finishing steps in the manufacture of cushioning bladders and alternatively to provide a clean, seamless appearance along the side walls. The inverted seam can be formed by attaching the peripheral edges of inner barrier layers to the outer barrier layers adjacent a weld between inner barrier layers to provide an inside-out inverted seam appearance. An inverted seam can also be formed by providing separate sidewall elements attached to the barrier layers of the bladder to provide a seam displaced from the center of the sidewall.

An apparatus, method and associated fiber-laser architectures for high-power pulsed operation and pumping wavelength-conversion devices. Some embodiments generate blue laser light by frequency quadrupling infrared (IR) light from Tm-doped gain fiber using non-linear wavelength conversion. Some embodiments use a fiber MOPA configuration to amplify a seed signal from a semiconductor laser or ring fiber laser. Some embodiments use the frequency-quadrupled blue light for underwater communications, imaging, and / or object and anomaly detection. Some embodiments amplitude modulate the IR seed signal to encode communication data sent to or from a submarine once the modulated light has its wavelength quartered. Other embodiments transmit blue-light pulses in a scanned pattern and detect scattered light to measure distances to objects in a raster-scanned underwater volume, which in turn are used to generate a data structure representing a three-dimensional rendition of the underwater scene being imaged for viewing by a person or for other software analysis.

A multiple camera vision system captures discrete images having overlapping fields of view. Each of the cameras is calibrated and the images from the cameras are stitched together as a stitched image. A stitched image from the multiple cameras is then used in a calibration process to prepare the multiple camera vision system to be used in connection with a processing operation. A stitched image is used as an input for identifying a feature of the material and for determining a tool path for the material. The tool path determined with the stitched image is provided to a process station to perform an operation on the material.

A method of reclaiming used tennis balls and transforming the material reclaimed from the tennis balls into soles for footwear. This multi-step process requires acquiring used tennis balls, grinding the tennis balls into ground rubber bits (usable elements) and tennis ball “fuzz” (unusable elements). The rubber and fuzz are passed through a screen which allows the rubber bits to exit the screen but retains the fuzz. The rubber is then mixed with an H2O and Polyurethane mixture to form a rubber mixture. This mixture is then pressed to a desired thickness in a hydraulic press, cured, and then cut out into a desired shoe sole shape and size which can be used to manufacture footwear.
