  • Patent number: 10595821
    Abstract: Described herein are example ultrasonic transducer device probes configured to be placed on a patient's body to direct an ultrasonic beam towards an internal structure inside the body and receive ultrasonic echo signals from the internal structure. A probe includes a housing in which an ultrasonic transducer is located, a transceiving face of the transducer being at an acute angle relative to a front plane of the housing. An accelerometer unit and a magnetic field sensing unit are also housed inside the probe. The transducer, accelerometer, and magnetic field sensing unit are embedded in a body of a first material comprising ultrasound non-sonolucent material. A front face of the body of the first material and a recess extending down to the transceiving face is covered by a body of a second material comprising ultrasound sonolucent material having a tacky or non-tacky front surface.

  • Patent number: 10408713
    Abstract: The present invention provides a method of analyzing a sample containing an analyte to be qualitatively and/or quantitatively determined, comprising a binding step and a washing step, wherein the binding step comprises: interacting the analyte with beads having a density m1; obtaining a structure of packed beads comprising quantifiable bead complexes having a density m2; and the washing step comprises: dispersing the packed beads in a liquid medium having a density d>m2 and m1; and separating the liquid medium and the beads comprising the quantifiable bead complexes.

  • Patent number: 10228308
    Abstract: A method for transferring beads in a fluidic chip having an internal fluid circuit through which various reactants, including beads, may be moved by use of centrifugal force includes providing beads having a density equal to, or lower than, m1 in a section of the fluid circuit, where the section includes at least a first outlet. The method includes providing a first liquid medium having a density d2 to the section, such that d2>m1, and applying a centrifugal force such that the beads migrate in an opposite direction of the centrifugal force.
