  • Electrical connector assembly with a connection indicator for a motor vehicle
    Patent number: 11916338
    Abstract: An electrical connector assembly includes a pair of electrical connectors for electrically connecting to one another to close an electric circuit. The assembly further includes a connection indicator attached to one or more of the electrical connectors. The connection indicator generates a feedback, in response to the electrical connectors being one of connected to one another and disconnected from one another. The connection indicator is separate from the electric circuit, and the feedback is at least one of a radio frequency signal (RF signal), an electronic signal, a visible light, and an acoustic signal.

  • Microfluidic technique for detection of multi-contact miscibility
    Patent number: 11684917
    Abstract: A microfluidic apparatus includes a substrate defining a microchannel having inlet and an outlet defining a length of the microchannel. The microchannel has a main channel extending from the inlet to the outlet, and a plurality of side cavities extending from the main channel. The cavities are in fluid communication with the main channel. A method includes introducing a sample into the microchannel through the inlet to fill the entire microchannel, and then introducing a solvent into the microchannel through the inlet at a controlled flow rate and inlet pressure. A developed solvent front then moves along the main channel from the inlet to the outlet while displacing the sample in the main channel. Images of the microchannel are acquired as the front moves, and a miscibility condition is determined based on the images.

  • Methods and apparatus for analysis of downhole asphaltene gradients and applications thereof
    Patent number: 7996154
    Abstract: A method and system for characterizing asphaltene gradients of a reservoir of interest and analyzing properties of the reservoir of interest based upon such asphaltene gradients. The analysis employs a correlation that relates insoluble asphaltene concentration to spectrophotometry measurement data measured at depth.
