  • Patent number: 10989181
    Abstract: Microfluidic pumps are provided that use electrowetting to manipulate the location of one or more droplets of a working fluid (e.g., water) in order to pump tears, blood, laboratory samples, carrier fluid, or some other payload fluid. The working fluid is separated from the payload fluid by one or more droplets of an isolating fluid that is immiscible with the working fluid. The working fluid is manipulated via electrowetting, by applying voltages to two or more electrodes, to repeatedly move back and forth. Forces, pressures, and/or fluid flows exerted by the working fluid are coupled to the payload fluid via the droplet(s) of isolation fluid and reed valves, diffuser nozzles, or other varieties of valve can act as flow-rectifying elements to convert the coupled forces into a net flow of the payload fluid through the pump.

The coil assembly includes a winding coil having an exposed portion, among which the exposed portion is extended along a second direction and disposed between the two first magnetic yokes, and the exposed portion is at least partially overlapped with the two first magnets in a third direction. As a result, the coil assembly and the case are driven to reciprocate along the first direction by the winding coil due to the magnetic force, thereby solving the magnetic disturbing issue, enhancing the driving force of the linear motor, and optimizing the mechanical rigidity.

  • Patent number: 9429012
    Abstract: A downhole salinity measurement and logging sensor system has multiple cells, each to measure conductivity, temperature and pressure of fluids at depths of interest in a wellbore. The multiple cells protect against effects of non-homogeneous wellbore fluids. The system also determines salinity of the liquid in the wellbore from conductance measurements, and stores the salinity data along with the temperature and pressure readings from the well. The sensors of conductivity, temperature and pressure are made using micro-fabrication technologies, and the system is packaged to comply with harsh downhole environments. The system may be deployed in the well with coiled tubing (CT), wireline or vehicles with a robotic system. The system can be deployed with an onboard memory, or with wireline surface access for real time access to measurement data or programming the device.
