Abstract: Cooktop temperature sensors and methods of operation are provided. An example cooktop appliance includes a cooktop element and a cooktop temperature sensor assembly. The cooktop temperature sensor assembly includes three springs providing support for a platform upon which a cooking vessel rests. The cooktop temperature sensor assembly includes a resistance temperature detector electrically connected to at least two of the three springs. The cooktop appliance includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the processor to perform operations. The operations include obtaining from the cooktop temperature sensor assembly a plurality of samples of a temperature. The operations include projecting a future temperature based at least in part on the plurality of samples of the temperature. The operations include controlling the cooktop element based at least in part on the projected future temperature.

Abstract: Dishwasher appliances and spray arm assemblies for dishwasher appliances are provided. An assembly includes an indexing assembly disposed between a conduit and a plurality of spray arms. The indexing assembly includes a disk rotatable about an axis and movable along an axial direction between a first position and a second position, the disk defining an aperture and a channel and comprising a plurality of cams projecting into the channel. The indexing assembly further includes a biasing element configured to urge the disk into the first position, and a boss assembly, the boss assembly comprising a boss extending into the channel of the disk, the boss defining a plurality of guide elements. The guide elements and cams are configured to interact such that movement of the disk along the axial direction between the first position and the second position causes the disk to rotate about the axis.

Abstract: The approaches presently disclosed provide for fault-interpretation in a seismic volume with computer assistance, allowing automatic or semi-automatic determination of a fault surface and associated displacement across the fault. The present fault interpretation approach uses pattern matching algorithms and does not require prior interpretation of the stratigraphic horizons. In certain implementations the fault interpretation approach estimates the 3D fault surface as part of a joint fault surface location and displacement optimization process.

Application number: 20150233916
Abstract: A centripetal microfluidic platform comprised of a microfluidics disc and a reader for testing LAL-reactive substances in fluid samples is provided. The microfluidic disc may comprise at least two testing areas wherein each testing area includes a reservoir portion for receiving at least one fluid sample. The disc may comprise a distribution network portion in fluid communication with the reservoir portion. Each distribution network portion may comprise a distribution network of at least four (4) channels, wherein each channel has a metering portion and at least one analysis chamber portion. The analysis chamber portion may comprise a mixing chamber for mixing samples and reagents and an optical chamber portion that is compatible with an optical reader. The metering portion may be sized to meter an aliquot of the fluid sample for analysis in the analysis chamber portion. At least one analysis chamber portion has at least one reagent isolated therein.

Abstract: Methods and systems for measuring the concentration of LAL-reactive substances in fluid samples is provided. They include contacting an aqueous sample with a detection reagent to form a prepared sample. A physical property of the prepared sample may be measured to obtain at least one sample measurement characteristic of the prepared sample. Curve fitting may then be used to forecast a concentration of the LAL-reactive substance the aqueous sample will have at a specified time in the future based on the sample measurement and a correlation developed between at least one standard measurement of a physical quality of a solution with a known concentration of a LAL-reactive substance therein. The quality of the sample measurement may be validated using historical data and/or the standard measurement.

Abstract: Various embodiments of a circuit breaker are described where a movable bridge connector is employed as part of the conductive path when the circuit breaker is in a closed configuration. When the circuit is opened, the connector is displaced from the two fixed contacts otherwise bridged by the connector. In one such embodiment, the circuit breaker utilizes the electromagnetic forces generated in response to the opening event to break the circuit.

Application number: 20150235794
Abstract: Embodiments of a tri-stable flexure mechanism are described where a resilient component is present that serves as both a structural component in the kinematic chain of the mechanism and as energy storing component of the mechanism. The resilient component maintains a movable arm and an input link in either a first stable state or a second stable state when the ends of the resilient component are held in place so that the resilient component has a state of high elastic strain energy. In a third stable state, where the resilient component is in a relaxed state of lower elastic strain energy, the mechanism may be in a tripped state distinct from the closed and open states.
