20100064780 | Pressure Determination In Microfludic Systems - Methods and apparatus for measuring changes in pressure in a fluidic system are described. In one aspect, an apparatus for measuring pressure as described herein includes a test channel (e.g., a first fluidic channel ( | 03-18-2010 |
20100192679 | SYSTEMS AND METHODS TO DETECT PARTICULATE DEBRIS IN A FLUID - Methods and systems are provided for detecting presence of a target particulate of predetermined size (e.g., engine wear debris) in a fluid (e.g., an engine lubricant) by providing at least one pair of serially fluid-connected upstream test and downstream reference filtration elements in the fluid. At least the upstream test filtration element has a filtration size rating that is sufficient to remove a predetermined amount of the target particulate from the fluid. The differential pressure of the fluid may then be measured (e.g., by suitable pressure transducers) across each of the test and reference filtration elements. By comparing the differential pressure across the test filtration element to the differential pressure across reference filtration element, the presence of the target particulate in the fluid can thereby be detected by an increase in differential pressure across the test filtration element in comparison to the differential pressure across the reference filtration element. The methods and systems of the invention thus allow for the detection of target particulates that is independent of the fluid flow rate and/or temperature (viscosity, density). | 08-05-2010 |
20110011165 | METHOD FOR PLANNING ROAD ASPHALTS - The subject of the present invention is a new method for designing road asphalts, comprising:—the determination of the optimal bitumen content with compacting experiments using samples made of asphalt mixtures; the optimal bitumen content being the one at which the receptive void volume has a minimum value, depending on the bitumen content; that is, where the compactness of the sample is the highest, and by changing the mass rates in the asphalt mixture, the bitumen content is set to the optimal bitumen content at most. The optimal bitumen content provides the possibility to aim for reaching the highest compactness, i.e. the smallest possible void volume which provides the most favorable fatigue and solidity characteristics. | 01-20-2011 |
20130333451 | GAS DELIVERY SYSTEM TO PROVIDE INDUCED PARTIAL SATURATION THROUGH SOLUTE TRANSPORT AND REACTIVITY FOR LIQUEFACTION MITIGATION - A system and method for providing a partial level of saturation to a mass of sand, through generation of gas bubbles, as a way to prevent liquefaction during earthquakes. The system includes a solution that is operable to generate gas bubbles and a solution generator that prepares the solution. A conduit delivers the solution to the sand, so that the solution generates the gas bubbles during and after being delivered to the sand. A probe may be used to determine whether the sand is susceptible to liquefaction before the solution is delivered and to assess a change in degree of partial saturation after the solution has been delivered. | 12-19-2013 |
20140013832 | CETANE NUMBER ESTIMATION DEVICE - In order to estimate the cetane number of a fuel, fuel injection is executed by controlling the driving of a fuel injection valve by a prescribed amount. The amount of change in the rotation of a diesel engine generated in response to the fuel injection is detected, and the cetane number of the fuel is estimated on the basis of this amount of change in the rotation. The actual amount of fuel injected from the fuel injection valve is detected, and when the difference between the amount actually detected and the prescribed amount is equal to or greater than a threshold value, the execution of the fuel cetane number estimation process is restricted. | 01-16-2014 |
