  • Publication number: 20240125543
    Abstract: Described herein are methods and systems for producing a liquefied natural gas (LNG) product by cooling and liquefying a natural gas stream via indirect heat exchange with a gaseous refrigerant and then flashing and separating the liquefied natural gas stream to obtain the LNG product. In particular, the gaseous refrigerant may be a refrigerant circulating in a reverse Brayton cycle. The gaseous refrigerant is warmed in the shell side first, second and third coil-wound heat exchanger sections each having a tube side and a shell side, the shell side of the first coil-wound heat exchanger section being separated from and operating at a different pressure to the shell side of the second and third coil-wound heat exchanger sections.

  • Patent number: 11388510
    Abstract: A compact multi-element microphone has two rings of directional sensors. Using simple analog electronics, it delivers first-order outputs with low noise, wide bandwidth and tight transient response. The double-ring structure provides exceptionally high directional fidelity in the horizontal plane, while also keeping out-of-plane behaviour under control. This enables faithful capture of ambience, reflections and reverberation. A non-radial capsule arrangement moderates cavity resonances and reduces shading. Combined with digital electronics, the array can efficiently provide second-order and higher-order horizontal directivities that maintain their performance over a wider frequency range than with prior solutions. Outputs can be mono, two-channel stereo and multichannel surround sound. Applications include 360-degree immersive audio, with-height concert hall recording, and advanced voice capture using electronic steering of beams and nulls.

  • Patent number: 10270352
    Abstract: A switching circuit, electrical energy converter, power management unit and energy harvesting system are described. Such apparatus is applicable to energy harvesting applications which involve a variety of transducers, either singly or simultaneously. The transducers may, for example, be photovoltaic, thermoelectric, piezoelectric, or electrodynamic. The described converters operate to convert impedances, voltages and currents. They incorporate inductive energy transfer elements, which are magnetically coupled. Different combinations of these energy transfer elements are used to obtain different conversion ratios, which can be referred to as “gears”. On the input side, having multiple gears enables easier and better matching to a wider variety of energy transducers. On the output side, it enables easier and better accommodation of a wider spread of energy storage voltages and of a wider variety of loads.
