  • Patent number: 9692187
    Abstract: An assembly of a cable connection apparatus and an electrical connector, includes a mating plug having an insulating body and multiple terminals, a circuit board having a notch depressed from an edge at a side of the circuit board toward a center direction of the circuit board and a metal conductor disposed in the notch or at an edge of the notch, and a cable having at least one conducting wire. The terminals are conducted to the circuit board. The conducting wire is inserted into the corresponding notch along a depression direction of the notch, and conducted to the metal conductor, thereby reducing the height of a soldering end of the conducting wire protruding from a surface of the circuit board. Thus, a metal casing outside the circuit board may wrap the circuit board without having a protruding portion for reserving the soldering end.

  • Publication number: 20170010204
    Abstract: The present invention provides methods and systems to combine the capabilities of a hematology analyzer with those of a flow cytometer to yield a far more powerful analytical system than either device alone. In one embodiment, a method of analyzing a cell sample includes receiving a first data generated by an analysis of a first aliquot of the sample on a first particle analyzer having a fluorescence measurement device such as a flow cytometer, detecting at least one unresolved cell population in the first data, and accessing a second data stored on a storage device wherein the second data was previously generated by interrogating a second aliquot of the sample using at least one of a cell volume measurement device and a cell conductivity measurement device in a second particle analyzer such as a hematology analyzer. The unresolved cell population in the first data is then resolved using the second data. Corresponding system embodiments are also disclosed.
