Abstract: A shaker mechanism for an agricultural harvester. The shaker mechanism adapted to shake a crop while the agricultural harvester is moving, wherein the shaker mechanism is operatively associated with the agricultural harvester so that the shaker mechanism is movable at zero velocity relative to the crop being shook while the agricultural harvester continuously moves at a non-zero velocity.

Abstract: A method and apparatus for determining whether a door is closed and locked. A door lock system includes a bolt, transmitter circuitry, and receiver circuitry. The bolt includes a first end that is extendible to engage a strike plate. The first end includes an opening, and channel extends from the opening longitudinally through the bolt. The transmitter circuitry is coupled to the bolt, and is configured to transmit a signal into the channel. The receiver circuitry is coupled to the bolt, and is configured to detect a reflection of the signal returned through the channel.

Abstract: Electrical power is provided to power consuming, heat-exhausting devices by multiple gas-fueled electrical power sources located near such devices. Exhaust heat from such devices is utilized as intake cooling air for the gas-fueled power sources, thereby excluding them from cooling capacity requirements. The gas piping delivering gas to gas-fueled power sources is positioned so as to be within hot aisles comprising exhaust heat. The gas piping is located up high for lighter than air gasses and near the floor for heavier than air gasses, with leak detection located nearby. Additionally, gas piping is externally coated with material that visually indicates a leak. By locating gas piping in the hot aisle, exhausted heat increases temperature and, thereby, pressure of the gas, resulting in more efficient gas distribution through the piping and preventing valve freezing. Furthermore, the gas piping is located after potential ignition sources in the airstream.

Abstract: A lanyard is provided. The lanyard may include a lanyard cord which is attached to a personal item such as safety glasses or an access card, an earplug cord which is attached to a first earplug and a second earplug, and a flexible retractable sheath. The lanyard cord and earplug cord may be disposed in the lumen of the retractable sheath and the retractable sheath is movable between a first position where it covers a first section of the lanyard cord and the earplug cord and a second position where it exposes the first section of the lanyard cord and the earplug cord.

Abstract: The current subject matter relates to compliant variable tension risers to connect deep-water subsea wellheads to a single floating platform in wet tree or dry try systems. The variable tension risers allow several subsea wellheads, in water depths from 1220 to 3050 meters, at lateral offsets from one-tenth to twice the depth or more, to tie back to a single floating platform. Also, the current subject matter relates to methods to counter buoyancy and install variable tension risers using a weighted chain ballast line.

Abstract: Disclosed are compliant variable tension risers (106) to connect deep-water subsea wellheads (102) to a single floating platform (104). The variable tension risers (106) allow several subsea wellheads (102), in water depths from 4,000 to 10,000 feet, at lateral offsets from one-tenth to one-half of the depth, to tie back to a single floating dry tree semi-submersible platform (104).
