Apparatus and methods for providing corrected readings in odor intensity level monitoring instrumentation and concurrent odor intensity and odorant concentration measurements
A system and method for concurrently measuring odorant concentration and also compensating for changes in relative air density when measuring odor intensity levels may be used to provide more accurate and reliable readings from an odorometer. Odorometers typically measure the concentration of a given target gas in a gas-air mixture. Because changes in air density make it difficult to accurately determine how much air is in the gas-air mixture sample, a method of compensating for changes in the air density is able to produce a more accurate concentration reading. By measuring the relative temperature and pressure of the air at calibration and when a particular reading is taken, the final reading can be corrected to account for changes in the air density. By correlating the odor intensity readings with odorant concentration readings a wide array of advantages may be realized. |

Acoustic resonance excited heat exchange
New exemplary heat exchange configurations that incorporate internal or external surfaces equipped with perturbators, for changing the thermal behavior of the system, or for modulating the surface temperature distribution of the flow surfaces. This is achieved by applying an acoustic wave to the fluid flow in a heat exchange passage, and selecting the frequency of the acoustic exciting wave to be the same as the acoustic resonance frequency of the heat exchange passage itself. As the traveling waves interact with the boundaries confining the heat exchange passages, constructive interference of the incident and reflected waves give rise to a standing wave. Thus, the heat exchange passages act as a resonator, and by superimposing this standing wave on the separating and reattaching fluid flow, significant heat transfer improvement can be achieved. This is accomplished without the need to significantly increase the pressure required to achieve the desired through flow. |

Determining a drift in the fuel static flow rate of a piezoelectric injector of a motor vehicle heat engine
The disclosure relates to a method for determining a drift in the static fuel flow rate of a piezoelectric injector of a motor vehicle combustion engine. The method relies on fluid-pressure measurements carried out in the injector supply chamber in order to calculate a measured static flow rate value. This value is compared against a nominal static flow rate in order to determine the existence, if any, and amplitude of the drift in the static flow rate. Furthermore, each pressure measurement is carried out when the valve of the injector is closed and the injector is open. In this way, the measured static flow rate calculation is not influenced by pressure-variation effects not relevant to the measurement. |

The web coating platform can be used for manufacturing solid lithium anodes for use in energy storage devices, for example, rechargeable batteries. The coating platform can be designed for double-sided coating of a continuous flexible substrate (e.g., a copper foil) with molten lithium followed by double-sided lamination or passivation. The coating platform integrates novel coating elements unique to handling and processing molten metals. For example, some implementations of the present disclosure incorporate double-sided molten metal coating elements, which include at least one of a molten metal application assembly (e.g., kiss roller, slot-die, Meyer bar, and/or gravure roller), a primary melt pool assembly, a secondary melt pool assembly, and an engagement mechanism. |
