  • Patent number: 11092561
    Abstract: The invention comprises a method and an analysing system for determining a quality of a hydrocarbon fluid. In an example, the electrical resistivity of the fluid is determined by means of a sensor device. The electrical resistivity is determined over time under predetermined conditions, and a change in the electrical resistivity is monitored over time. A change in fluid visocity may also be determined and monitored over time. The analysing system provides information about an absolute value of a difference of a total base number and a total acid number based on the monitored resistivity change that relates to the quality of the fluid for providing an indication of the remaining useful life of the fluid. In an example, the information about the fluid may correlate to oxidation and/or nitration of the fluid when a change in fluid visocity is below a predetermined threshold.

  • Patent number: 10801966
    Abstract: A method and testing apparatus determine receding contact angles of liquids on surfaces by depositing a liquid in a manner whereby the volume of the drop is increased through stepwise addition of smaller drops. Each increment of volume growth causes the perimeter of the drop to advance across the surface. The incremental volume elements impart sufficient energy to the growing drop such that the drop perimeter expands beyond its equilibrium diameter for that volume. The drop perimeter tends to contract between volume additions as the excess energy is dissipated. The method and testing apparatus determine the receding contact angle between the incremental volume additions.

The method includes analyzing the contamination data to determine parameter data describing modifications for a set of parameters for an advanced driver assistance system (“ADAS system”) that control the operation of the ADAS system, wherein the parameter data is operable to update the set of parameters and thereby modify the operation of the ADAS system to compensate for the amount of water present in the vehicle fluid so that vehicle component performs as though the vehicle fluid is substantially not contaminated by water.

  • Patent number: 10065187
    Abstract: A method of evaluating an asphaltene inhibitor includes providing a centrifugal microfluidic system including: a disc mounted to rotate about an axis; a microfluidic device mounted on the disc, the device having sample, solvent, inhibitor, and precipitant reservoirs and an analysis chamber in fluid communication with the sample, solvent, inhibitor, and precipitant reservoirs; and an optical detection system coupled to the analysis chamber and configured to measure the optical transmission of fluid in the analysis chamber. The method includes filling the sample, solvent, inhibitor, and precipitant reservoirs, respectively, with a sample, solvent, inhibitor, and precipitant; rotating the disc to generate centrifugal force to cause the sample, solvent, inhibitor, and precipitant to travel radially outward to the analysis chamber; and measuring the optical transmission of a mixture of the sample, solvent, inhibitor, and precipitant in the analysis chamber as a function of radial distance of the analysis chamber.

  • Patent number: 9932482
    Abstract: The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS). Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). SLIPS outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (<2.5°), quickly restore liquid-repellency after physical damage (within 0.1-1 s), resist ice, microorganisms and insects adhesion, and function at high pressure (up to at least 690 atm). Some exemplary application where SLIPS will be useful include energy-efficient fluid handling and transportation, optical sensing, medicine, and as self-cleaning, and anti-fouling materials operating in extreme environments.

    Abstract: A method of detecting the extent of degradation of an oil is provided. The method may comprise the steps of analyzing samples of the oil when fresh and when used; calculating electrochemical property data of the fresh and used engine oil; determining whether the electrochemical property data correlates with the degradation marker data; and using the electrochemical property to detect the extent of degradation of the oil of a used sample of the oil. The method may be used for any suitable oil, including mineral oil, synthetic oil and blends (a.k.a. semi-synthetic). The method can be used to maximize oil usage by monitoring used oil quality over time so that the oil is replaced when necessary and not before. The method can also identify trends in oil degradation.
