A storage system is provided that implements a file system configured to optimize the amount of readahead data retrieved for each read stream managed by the file system. The file system relies on various factors to adaptively select an optimized readahead size for each read stream. Such factors may include the number of read requests processed in the read stream, an amount of client-requested data requested in the read stream, a read-access style associated with the read stream, and so forth. The file system is also configured to minimize cache pollution by adaptively selecting when readahead operations are performed for each read stream and determining how long each read stream's retrieved data is retained in memory.

A hybrid fuel/electric powered watercraft includes an electronic turning machine (ETM), and internal combustion engine, and a propulsion system, which are operatively connected to each other, preferably via one or more clutches. An electronic control unit (ECU) controls the ETM, clutch(es), and engine. At low speeds, the ECU disengages at least one clutch and solely uses the ETM to power the propulsion unit and propel the watercraft. At high speeds, the ECU engages the clutch and uses both the engine and the ETM or just the engine to power the propulsion system. When the watercraft's battery discharges, the ECU operates the ETM in a generator mode and runs the engine to charge the battery. The watercraft can also include a shore button feature that selectively limits/governs the speed of the watercraft. A clutch may be used to avoid driving the propulsion system when the engine is idling or being started.

Luminaires for illumination of vertical surfaces of predetermined dimensions such as billboards or similar signs, the invention in several embodiments takes the form of reflector assemblies capable of directing light from a light source disposed within each of said luminaires either directly to the vertical surface or to refractive structures located on the luminaires for redirection of light to the vertical surface for even illumination of said surface with minimal light pollution from “spill” light. Lamps used in embodiments capable of providing asymmetrical light distributions are located toward one or the other of side portions and are preferably vertically oriented. A main reflector is curvilinear in conformation and functions in concert with a secondary reflector located directly behind the lamp to direct light onto desired portions of a vertical surface. Luminaires configured according to the invention also utilize side reflectance panels for light control and for maximizing light directed onto a vertical surface, said luminaires also preferably including refractive lens elements for redirection of light onto the vertical surface. The reflector assemblies of the invention are mounted within weather-tight housings, the refractive structures conveniently being disposed on or formed integrally with a transparent glass or plastic cover that completes the housing, said cover being located between the lamp and the vertical surface to be illuminated. Efficiencies occasioned by the present luminaires permit illumination of billboards and similar signs of standard dimensions with only two of the luminaires and with full and even illumination with minimal light spillage, a capability approached previously in the art only with a greater number of luminaires.

The invention provides a method for preparing a corrosion-resistant super-hydrophobic coating and a product thereof.

A single main steel wheel rides on a single main steel rail of a guideway to support and drive a carrier and to facilitate steering and provide a simplified, more compact and less costly construction. The carrier can support a car through a platform having elements and chocks for locking contact with a front bumper and front wheels of the car Auxiliary wheels and rails cooperate to cause nearly all weight to be carried through the single main wheel. Traction is increased when necessary through application of increased upward forces to undersides of auxiliary rails and/or through developing magnetic forces between the steel wheel and steel rail. An AC induction motor is a main source of drive power. Acceleration and braking are assisted through epicyclic gearing, braking means and a DC motor/generator that is connected to a battery and that drives the carrier if supply of AC fails.

An egg candling method for determining a state of eggs between the 13^th and the 17^th day of incubation, particularly for identifying with certainty the living or dead state of that egg. The egg is illuminated with a green or blue light to visually show on the shell a shadow of the blood network supplying the embryo of the egg if it is present in the egg. At least one image of the egg is acquired then processed in order to determine a vitality level of the egg, based on the presence or not of this blood network and the size of the veins of said blood network. The method also determines the presence or absence of air cell in the upper portion of the egg and to thus define the inverted or uninverted position of the egg. Finally, the method also makes it possible to detect lesions on an egg shell and particularly cracked shells.

A lubrication system for a gear system for a wind turbine is disclosed. The lubrication system comprises a reservoir adapted to contain lubricant, first pump means arranged to supply lubricant from the reservoir to the gear system via a first fluid connection, and vacuum generating means arranged in fluid connection with the reservoir, thereby maintaining a total air pressure in the reservoir which is lower than an ambient pressure during normal operation. The lowered total air pressure in the reservoir draws lubricant from the gear system into the reservoir, thereby increasing the lubricant level in the reservoir and decreasing the lubricant level in the gear system, allowing the lubrication system to be operated in a ‘dry sump mode’. In the case of an emergency or during start-up the vacuum generating means is stopped, thereby increasing the total air pressure in the reservoir. This causes a decrease in the lubricant level in the reservoir and an increase in the lubricant level in the gear system, allowing the lubrication system to be operated in a ‘wet sump mode’.
