20090183858 | Venturi for Heat Transfer - Heat pumps consume power in order to transfer heat from a source to a higher-temperature sink. This invention enables spontaneous heat transfer from a heat source to a small portion of the generally warmer working fluid that is cooled locally by the Bernoulli effect to a temperature below that of the heat source. The Bernoulli effect occurs in a Venturi shaped duct shaped to maintain attached flow. Heat-transfer efficiency is improved by restriction of the heat transfer to a small portion of the Venturi in which the flow temperature, velocity, pressure gradient and the Nusselt effect enhance heat transfer. Within this region, heat transfer is maximized by a thermally conducting grid extending across the Venturi neck. | 07-23-2009 |
20090249806 | BERNOULLI HEAT PUMP WITH MASS SEGREGATION - Embodiments of a heat transfer apparatus, and related methods, involve a curved flow path, a heat source external to and in thermal communication with at least a portion of an inner radial boundary of the curved flow path, and a working fluid, including a heavier component and a lighter component, flowing through the flow path. The flow path causes the working fluid to experience centrifugal force so as to preferentially force the heavier component toward the exterior wall portion and thereby cause the lighter component to preferentially absorb heat from the interior wall portion. | 10-08-2009 |
20090277192 | CENTRIFUGAL BERNOULLI HEAT PUMP - Heat pumps move heat from a source to a higher temperature heat sink. This invention enables spontaneous source-to-sink heat transfer. Spontaneous heat transfer is accomplished by conducting heat from the source through rotating disks to a portion of the generally warmer sink flow that is cooled to a temperature below that of the source by the Bernoulli effect. The nozzled flow required for Bernoulli cooling is provided by the corotating disk pairs. The distance between the opposing surfaces of the disk pair decreases with distance from the rotation axis, forming a nozzle. The heat-sink flow through the nozzle is maintained by centrifugal force caused by the circular motion of the gas near the disk surfaces. Embodiments of the invention differ in the paths followed by the source and sink fluid flows, by the number of disk pairs and by the state (gas or liquid.) of the heat source. | 11-12-2009 |

20140355879 | Computationally Efficient Scene Classification - The disclosure describes novel technology for inferring scenes from images. In one example, the technology includes a system that can determine partition regions from one or more factors that are independent of the image data, for an image depicting a scene; receive image data including pixels forming the image; classify pixels of the image into one or more pixel types based on one or more pixel-level features; determine, for each partition region, a set of pixel characteristic data describing a portion of the image included in the partition region based on the one or more pixel types of pixels in the partition region; and classify a scene of the image based on the set of pixel characteristic data of each of the partition regions. | 12-04-2014 |

20100288211 | Fuel system and method for burning liquid ammonia in engines and boilers - A process and apparatus is provided for burning liquid ammonia in an energy device such as a diesel engine, boiler or gas turbine. In particular, the process and apparatus include mixing a renewable fuel with a low flame speed and high ignition temperature, e.g., ammonia, with a combustible liquid fossil or bio-fuel and supplying the mixture into a closed fuel loop where part is efficiently burned in an engine combustion chamber, and part is used to cool the engine and returned by the loop for mixture with fresh incoming fuel mixture. The invention provides for the mixing and emulsifying in such a way that vapour lock is avoided. In the loop, the mixture is emulsified into a disperse distribution of fuel droplets such that upon injection of a portion into the combustion chamber, the renewable fuel in an emulsified droplet evaporates, mixes with the air and forms a small combustion cell surrounding the liquid fuel droplet. The fuel droplet burns and then serves as an ignition kernel for the gas mixture in the small combustion cell producing efficient and rapid combustion of the renewable fuel. The fuel loop allows the fuel system to automatically scale for engines varying in power output from 1 to 35,000 horsepower. | 11-18-2010 |
