摘要： A single-acting (two pistons) or double-acting (four pistons) alpha configuration Stirling engine has increased thermal exchange between a hot piston crown and a hot head and between a cold piston crown and a cold head of each piston cylinder assembly, increasing conversion of thermal energy to mechanical motion. The thermal exchange is provided by presenting corresponding transverse peaks and valley that create increased surface area and increased convective fluid flow rate for a working gas sealed in the Stirling engine.

摘要： Multi-spectral methods and systems for the day and night remote sensing (detection, identification, and quantification) of greenhouse gas emission sources from space are provided. The sensor system includes a telescope assembly that passively collects light from an observation area and directs that light through spectral, optical filters and to a sensor array having a plurality of rows and columns of pixels. Different groups of sensor array pixel rows are aligned to receive light that has passed through different optical filters. The filters have passbands corresponding to the reflective and emissive bands of gases of interest, as well as associated reflective and emissive reference bands, and broadband spectral bands. A set of image data frames is obtained as the field of view of the sensor system moves over an observation area and an aggregate image showing locations of detected gas emissions is generated using the collected data.

摘要： An expander unit of a cryogenic refrigerator device includes a moving assembly with a porous regenerative heat exchanger configured to move back and forth along a longitudinal axis. A magnetic spring assembly includes a stationary magnetic assembly fixed to the cold finger base that includes one or more magnetic rings fixedly arranged about a bore. A movable magnetic assembly includes one or more movable magnetic rings fixed to the moving assembly, An outer lateral dimension of each of the movable magnetic rings is less than an inner lateral dimension of the bore. The stationary magnetic assembly and the movable magnetic assembly are configured such that, when the moving assembly is displaced along the longitudinal axis from an equilibrium position, attractive and repulsive forces between the movable magnetic assembly and the stationary magnetic assembly yield a restoring force that is directed to restore the moving assembly to the equilibrium position.

摘要： A dilution refrigerator, such as for a quantum computing system, includes a cryostat having a plurality of temperature-controlled flanges inside a vacuum chamber. A dilution unit is disposed inside the cryostat and operable to cool a first group of the flanges. A continuous flow helium refrigerator is in heat transfer communication with a lowest temperature flange of a second group of flanges, disposed at progressively lower temperatures that are greater than those of the first group of flanges, to provide primary cooling thereto to a first temperature. The continuous flow helium refrigerator resides at least partially in the cryostat and includes a helium liquefier and a first closed-loop circuit thermally coupling the helium liquefier to the lowest temperature flange of the second group of flanges. The helium liquefier provides liquid helium to the lowest temperature flange of the second group of flanges via the first closed-loop circuit.

摘要： The invention provides a device for the inductive compression of carbon dioxide via isochoric heating. The resulting hot, supercritical or compressed carbon dioxide is suitable for driving a gas turbine with highly efficient use of the input thermal energy, for local heating and cooling applications, and for pipeline transportation to remote locations where the high enthalpy content of the gas can be harvested.

摘要： A method includes generating a first varying electromagnetic field using a first voice coil of a first actuator. The method also includes repeatedly attracting and repelling a first magnet of the first actuator based on the first varying electromagnetic field. The first voice coil is connected to a first piston of a compressor, and the first magnet is connected to an opposing second piston of the compressor. Attracting the first magnet narrows a space between the pistons, and repelling the first magnet enlarges the space between the pistons. The method may further include generating a second varying electromagnetic field using a second voice coil of a second actuator and repeatedly attracting and repelling a second magnet of the second actuator based on the second varying electromagnetic field. The second voice coil may be connected to the second piston, and the second magnet may be connected to the first piston.
