摘要： A magnetic refrigeration apparatus includes one or more beds of magnetocaloric material arranged along a circumferential direction. The apparatus also includes a heat transfer fluid, one or more hot side heat exchangers (HHEX), one or more pumps or fluid displacement devices configured to move the heat transfer fluid, and a magnetic-field source. The magnetic-field source generates magnetic flux oriented substantially in a radial direction through the beds. The field source advantageously includes one or more pole pieces, one or more axial-end magnets, and one or more axial-end flux return pieces. Additionally, one or more circumferential flux returns, one or more gap flux return pieces, one or more side magnets, and one or more side flux return pieces can be added to increase system performance and reduce cost.

摘要： A dual-mode magnetic refrigeration apparatus includes beds of magnetocaloric material, a magnet to apply a time-varying magnetic field to the beds, a heat transfer fluid (HTF), a pump to circulate the HTF, a hot side heat exchanger (HHEX), a cold side heat exchanger (CHEX), valves to direct flow of the HTF, and a controller configured to control periodic switching of the valves to allow the apparatus to operate in a first mode and in a second mode. The first mode transfers heat from the CHEX to the HHEX. In the second mode of operation, the periodic switching of the valves is suspended to allow unidirectional flow of the HTF through the HHEX, the beds, and the CHEX such that heat is transferred from the HHEX to the CHEX.

摘要： A color balanced solid-state backlight provides feedback control of each color using a single photodetector by imposing a modulation pattern on the solid-state lamps revealing individual colors to the photodetector. The photodetector signal provides feedback controlling color balance over a small range of instantaneous brightness less than larger range of average brightness of the display to provide for accurate color balance throughout a large range of average brightnesses.

摘要： A permanent magnet assembly is disclosed that utilizes at least two rotating magnet subassemblies, and first and second stationary magnet subassemblies arranged so that their magnetic vectors oppose each other. At a first rotational position of the rotating magnet subassemblies, the magnetic vectors of the rotating magnet subassemblies align with the magnetic vector of the first stationary magnet subassembly and oppose the magnetic vector of the second stationary magnet subassembly. At a second rotational position, the magnetic vectors of the rotating magnet subassemblies are reversed, thereby aligning with the magnetic vector of the second stationary magnet subassembly and opposing the magnetic vector of the first stationary magnet subassembly. By locating air gap portions where the magnetic vectors of the rotating magnetic subassemblies meet the magnetic vectors of the stationary magnetic subassemblies, the air gap portions are subjected to a time-varying magnetic flux density.

摘要： A magnetic refrigeration apparatus has an annular container including a plurality of magnetic regenerator compartments containing magnetocaloric material, and a magnet mounted for rotation around the annular container, whereby the motion of the magnet produces a variation of magnetic field strength in the magnetic regenerator compartments, which in term leads to a variation in temperature of the magnetocaloric material in the magnetic regenerator compartments. Heat transfer fluid is propelled by a pump, and directed to and from the regenerator compartments and hot and cold heat exchangers by valves. Each valve includes an axial port and a plurality of radial ports.

摘要： A magnetic field transfer device includes a pair of oppositely wound inner coils which each include at least one winding around an inner coil axis, and an outer coil which includes at least one winding around an outer coil axis. The windings may be formed of superconductors. The axes of the two inner coils are parallel and laterally spaced from each other so that the inner coils are positioned in side-by-side relation. The outer coil is outwardly positioned from the inner coils and rotatable relative to the inner coils about a rotational axis substantially perpendicular to the inner coil axes to generate a hypothetical surface which substantially encloses the inner coils. The outer coil rotates relative to the inner coils between a first position in which the outer coil axis is substantially parallel to the inner coil axes and the outer coil augments the magnetic field formed in one of the inner coils, and a second position 180.degree. from the first position, in which the augmented magnetic field is transferred into the other inner coil and reoriented 180.degree. from the original magnetic field. The magnetic field transfer device allows a magnetic field to be transferred between volumes with negligible work being required to rotate the outer coil with respect to the inner coils.

摘要： A method and apparatus for using portable electronic devices such as commercial off-the-shelf cell phones and tablets for the communication of critical aviation data provides a protocol which minimizes processing by the portable electronic device other than the confirmation of a receipt of uncorrupted data. Failure of timely, accurate communication is detected at a certified avionics data server and communicated to the portable electronic device in the form of a fail-image. The communicated images may be composited with animated frames to provide a human recognizable indication of data integrity.

摘要： An active magnetic regenerative (AMR) refrigerator apparatus can include at least one AMR bed with a first end and a second end and a first heat exchanger (HEX) with a first end and a second end. The AMR refrigerator can also include a first pipe that fluidly connects the first end of the first HEX to the first end of the AMR bed and a second pipe that fluidly connects the second end of the first HEX to the first end of the AMR bed. The first pipe can divide into two or more sub-passages at the AMR bed. The second pipe can divide into two or more sub-passages at the AMR bed. The sub-passages of the first pipe and the second pipe can interleave at the AMR bed.
