Abstract: An apparatus and method for connecting an end of a first fiber optic cable to an end of a second fiber optic cable, the apparatus comprising a first fiber optic cable comprising at least one plastic fiber, a second fiber optic cable comprising at least one plastic fiber, a first fitting have a cavity for securing the end of said first fiber optic cable, a second fitting for securing the end of said second fiber optic cable, and a connector for joining the first fitting to the second fitting to hold the end of the first fiber optic cable in alignment with the end of the second fiber optic cable to allow light to pass therebetween.
Abstract: A waterfall illuminated by a plurality of optical fibers having their ends disposed into an outlet of the waterfall and directing light from the fiber ends onto water within the waterfall. The waterfall comprises a water conduit having an inlet for receiving water into the interior of the water conduit and having an outlet formed by a top plate and bottom plate for producing a waterfall as the water flows out of the water conduit, a fiber optic cable bundle attached to the water conduit, and the fiber optic cable bundle comprising a plurality of fibers where each fiber adapted to receive light at an input end and to emit light at an output end. The output ends of the respective fibers are disposed within the outlet whereby the output ends are positioned to direct light onto water in the outlet.
Abstract: A method for processing monitored data from a remote asset to optimize maintenance and operation schedules, the method comprising the steps of collecting data from the remote asset, building a data set based on the data collected, applying statistical scripts to the data set to create a statistical model, comparing the statistical model to the data set, creating a standardization model from the compared statistical model and the data set, applying a trending algorithm to the data, deriving statistical based control limits, and applying the control limits to a new set of collected data.
Abstract: A distributed power system for remotely controlling a locomotive, the system comprising a position-determining device for determining a position of the locomotive, a pre-stored track database comprising terrain and contour data about a railroad track, a track database integrity monitor for detecting errors with the pre-stored track database, a processor comprising an algorithm to determine a distributed power for the locomotive and to use the track database integrity monitor to determine if errors exist in the pre-stored track database, and a memory device connected to the processor.
Abstract: A system and method for using a relatively high voltage power source on a locomotive to power a windshield wiper system that is capable of operating at variable and interval delay speeds comprising a first DC electric motor, a second DC electric motor, a controller operatively connected for enabling operation thereof, and a convertor power supply connected to the relatively high voltage power source where the convertor has a dynamic response characteristic emulating the electric power characteristics of a conventional vehicle battery whereby the convertor can be rated for supplying nominal motor current but can supply relatively high currents to the first DC motor to allow the motor to overcome stalled conditions
Abstract: A harvesting apparatus for dislodging produce from trees comprising a support structure, a boom vertically placed where a first end is connected to the support structure, a positioning apparatus to position a second end of the boom radially from the first end, horizontal posts connected to the boom wherein a first post is positioned above a second post, crank arm rotatably connected between the horizontal posts along an axis where the crank arm has a plurality of elbows, one of a plurality of spools rotatably attached to the crank arm at each respective elbow whereby each spool is free to rotate axially, a plurality of wands axialy attached to each spool and spaced around each spool, and a rotating apparatus for rotating the crank arm about its axis.
Abstract: A waterfall apparatus comprising a water confining base, said base including a bottom and a plurality of upwardly extending side walls connected to said bottom; a water inlet connected to said base for providing a path of travel for water entering said base; a water outlet connected to said base, said water outlet including an upper lip connected to at least a first one of said plurality of side walls and extending outwardly therefrom, and a lower lip spaced apart from said upper lip, connected to at least to a second one of said plurality of side walls, and extending outwardly therefrom so that water positioned within said base flows between said upper and lower lips and outwardly and downwardly therefrom; a water flow guiding arm connected to said base and extending downwardly at a predetermined angle therefrom into the inner confines of said base to provide a water flow path of travel from said water inlet, around said guiding arm and from said water outlet, the predetermined angle being less than 90 degre
Abstract: A method and system for detecting and correcting a Hot Manifold condition that occurs in turbocharged diesel engines where intake air used for combustion exceeds an acceptable operating temperature where sensors monitor conditions indicative of the Hot Manifold condition and power level reduction, speed control limits, varying coolant system operations, and cycling flow valves are controlled by a processor to correct the Hot Manifold condition.
Abstract: An apparatus for deploying a propeller assembly from a folded configuration to a deployed, operational configuration, the apparatus comprising a propeller assembly hub which in conjunction with a propeller hub nut maintains an aerodynamically efficient shape after the propeller assembly is deployed, the propeller hub nut which is diametrically large enough to allow assembly of a drive shaft and a drive shaft bevel gear and includes a cavity to accept a spring detent, a propeller blade which protrudes from a journal located in the surface of the propeller assembly hub where when in its folded configuration, the propeller blade is in the same parallel axial direction as the drive shaft and when deployed is nutated to a radially outwardly extending operative position in response to rotating of a propeller blade bevel gear, the drive shaft rotated about its axis where one end engages a prime mover and a second distal end engages the hub nut, drive shaft bevel gear fixed to the drive shaft near the distal end whic
Abstract: A woodwind instrument reed maintenance device that extends the life of a used reed by removing the tip of the reed by burning. The device achieves extended life, and a brighter or a more projected sound from a used reed due to the cauterization of the woody longitudinal fibers called vascular bundles, running vertically the entire length of the reed. The device holds the reed securely and is designed to retain the burned tip at the precise angles or arc of the cut of the tip so as to maintain a working relationship with the woodwind mouthpiece. In addition, the top portion utilizes an angled tip to not only secure the reed in the device, but to prevent back burn to playable areas of the reed surfaces.
