  • Method for selectively washing used reaction cuvettes in an automatic analyzer
    Patent number: 7540294
    Abstract: A method for cleansing used reaction cuvettes so that whenever certain assays are to be or have been performed in the reaction cuvette, the cuvette is automatically subjected to an additional cleaning operation by providing a number of washing and drying manifolds, each of which is independently selectively activated to perform or not perform a cleaning operation.
    Type: Grant
    Filed: October 17, 2007
    Date of Patent: June 2, 2009
    Assignee: Siemens Healthcare Diagnostics Inc.
    Inventors: Ching-Cherng Lee, Donald Richard Phillips, Sr., Arnold Lloyd Lewis, William Jackson Devlin, Sr.

  • Method and apparatus for capacitively determining the uppermost level of a liquid in a container
    Patent number: 7150190
    Abstract: A liquid level sensor confirms actual physical contact between a probe and a liquid by verifying that any change in capacitance of the sensor is constant over a given time period and thereby is not caused by spurious electrical disturbances or other measuring irregularities.
