  • Patent number: 10533972
    Abstract: A fluidic device includes at least one bulk acoustic wave (BAW) resonator structure with a functionalized active region, and at least one first (inlet) port defined through a cover structure arranged over a fluidic passage containing the active region. At least a portion of the at least one inlet port is registered with the active region, permitting fluid to be introduced in a direction orthogonal to a surface of the active region bearing functionalization material. Such arrangement promotes mixing proximate to a BAW resonator structure surface, thereby reducing analyte stratification, increasing analyte binding rate, and reducing measurement time.

    Abstract: A method for the estimation of oil viscosity in an internal combustion engine, the engine subjected to fuel post injections to activate Particulate Filter regeneration processes and to fuel hydrocarbons (HC) evaporation events affecting said oil viscosity. The method includes, but is not limited to determining if the particulate filter is subjected to a regeneration process and, in the affirmative case, calculating an oil viscosity decrease during said Particulate Filter regeneration process as a function of an oil dilution rate, and calculating an oil viscosity increase after said regeneration process as a function of an Hydrocarbon (HC) evaporation rate and of a time during which fuel Hydrocarbon evaporation takes place, where said evaporation time is determined as a function of a time spent in evaporating fuel Hydrocarbon from engine oil in a previous fuel hydrocarbons evaporation event.

  • Patent number: 8586368
    Abstract: Methods, systems, and computer readable media for using actuated surface-attached posts for assessing biofluid rheology are disclosed. According to one aspect, a method for testing properties of a biofluid specimen includes placing the specimen onto a micropost array having a plurality of microposts extending outwards from a substrate, wherein each micropost includes a proximal end attached to the substrate and a distal end opposite the proximal end, and generating an actuation force in proximity to the micropost array to actuate the microposts, thereby compelling at least some of the microposts to exhibit motion. The method further includes measuring the motion of at least one of the microposts in response to the actuation force and determining a property of the specimen based on the measured motion of the at least one micropost.

  • Publication number: 20130186184
    Abstract: A method and apparatus for measuring the viscosity of a sample solution. A capillary (2) having first and second spaced apart detection windows (W1,W2) is filled with a carrier solution. A plug (4) or a continuous volume (4) of a sample solution is injected into the first end of the capillary (2) and pumped through the capillary (2) at a first pump pressure passing through the first and second detection windows (W1,W2). At least part of each detection window (W1,W2) is illuminated with a light source. Light from the light source passing through the carrier solution or the sample solution at each detector window (W1,W2) is detected using an array detector (6) comprising a two dimensional array of detector locations which generates an array detector output signal indicative of the profile of light absorbance of the sample solution plug (4) or flow front (4) passing through each detection window (W1,W2).
