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： Heat regenerators and related methods enable heat transfer in an embedded structure of a heat regenerator. The heat regenerators enable a reduction of the pressure drop due to fluid flow through the heat regenerator and consequently an increase of power density. A heat regenerator includes a housing having a primary hot heat exchanger and a primary cold heat exchanger between elements for the oscillation of a primary fluid. The secondary fluid unidirectionally flows from the heat sink into the primary cold heat exchanger. The secondary fluid exits from the primary cold heat exchanger and unidirectionally flows towards the heat source. The secondary fluid S enters the primary hot heat exchanger and exits as the unidirectional flow of the secondary fluid S of the primary hot heat exchanger towards the heat sink. Between both primary heat exchangers, the porous regenerative material is positioned as part of the regenerator.

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 thermoacoustic system for transfer of energy by an acoustic wave, includes a process volume. The process volume is filled with a fluid through which the acoustic wave propagates, and includes
an acoustic network including a compliance volume, a thermoacoustic core and a fluidic inertia; the thermoacoustic core including a cold heat exchanger, a hot heat exchanger and a regenerator; the cold heat exchanger arranged on a first side of the hot heat exchanger with the regenerator between the hot and cold heat exchangers; a thermal buffer zone is positioned adjoining the hot heat exchanger on a second side thereof.
The thermoacoustic system includes a partitioning element that is arranged in the thermal buffer zone adjacent to the hot heat exchanger. The partitioning element is configured for blocking mass flow of the fluid through the thermal buffer zone in a direction of acoustic wave propagation in the thermal buffer zone, while allowing passage of the acoustic wave through the thermal buffer zone.-

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.
