Abstract: Methods and systems for spatial data encoding and decoding are described. A tile may be designated within a source frame. The tile may be divided into at least one bit area. A particular message bit value of a message may be accessed. A statistical property calculation may be performed on a pixel variable value of available pixels within the tile. A pixel variable value of pixels in the particular bit area of a target frame may be shifted to encode a particular message bit. A particular pixel variable value of a particular pixel of the plurality of pixels may be shifted by a shift value. The shift value may be in accordance with the statistical property calculation, the particular message bit value, and a particular modulation pattern value of the plurality of modulation pattern values for the particular pixel within the particular bit area.

Abstract: A breakaway coupling for a fuel supply hose includes a male valve body interfitting with a female valve body for defining a fuel passage, and the valve bodies enclose axially movable spring biased poppet valve members. The valve bodies are connected by a permanent magnetic coupling system which provides for moving the valve bodies from a connected position to a disconnected position in response to a substantial axial tension force on the valve bodies. In one embodiment, the coupling system includes an annular strike member surrounding the fuel passage and a mating annular magnet member supporting a plurality of circumferentially spaced permanent magnets of rare earth materials. In another embodiment, the valve bodies define a vapor return passage with a poppet valve member and disposed either radially outboard or inboard of the fuel passage. The magnetic coupling system also simplifies reconnecting the valve bodies.

Abstract: This invention is a cryogenic fluid transportation and supply system and method for transporting the cryogenic fluid in a liquefied state and alternatively offloading the cryogenic fluid as compressed gas and liquid. The system includes a mobile support means, and a cryogenic storage vessel for storing the cryogenic fluid as liquid. To deliver the cryogenic fluid as compressed gas, the system includes a piston-type pump, a heat exchanger, a compressed gas conduit and a compressed gas connection fitting. To deliver the cryogenic fluid as liquid, the system includes a liquid line in communication with the cryogenic storage vessel and a liquid cryogenic fluid connection fitting. An internal combustion engine of a motor vehicle used for moving the mobile support means may power the pump and an optional fan for the heat exchanger. A hydraulic system may be used to transfer the power between the internal combustion engine and the pump.

Abstract: A breakaway coupling for a fuel supply hose includes a male tubular valve body interfitting with or female tubular valve body and defining a fuel supply passage, and the valve bodies enclose axially moveable spring biased valve members. The valve bodies are connected by releasable connecting means which provide for moving the valve bodies from a connected position to a disconnected position in response to a substantial axial tension force on the valve bodies. The valve bodies have cooperating peripherally extending and opposing cam surfaces effective to move the valve bodies from the connected position to the disconnected position in response to relative rotation of the valve bodies and cam surfaces. The valve bodies may also define a vapor return passage with an axially movable valve member and disposed either radially outboard or inboard of the fuel supply passage.
