  • Electrical multi-layer component
    Patent number: 8022605
    Abstract: A piezoelectric multi-layer component is described herein. The component includes a plurality of ceramic layers, and one or more electrode layer. The one or more electrode layer has a material structure that is different than the plurality of ceramic layers and is configured to at least partially block a propagation in a longitudinal direction of pressure waves acting on the piezoelectric multi-layer component.
    Type: Grant
    Filed: March 16, 2007
    Date of Patent: September 20, 2011
    Assignee: EPCOS AG
    Inventors: Michael Hirschler, Helmut Sommariva, Peter Stimpfl
  • Oximeter for spectro-photometric in-vitro determination of hemoglobin derivatives
    Patent number: 7710550
    Abstract: An oximeter for spectro-photometric in-vitro determination of hemoglobin derivatives in a sample, typically a hemolyzed blood sample, is provided comprising a single measurement light source emitting measurement radiation, a sample chamber, for instance a measurement cuvette containing the sample, a detector device, which records a spectrum of the measurement radiation after its interaction with the sample, and an evaluation unit following the detector device, which determines the hemoglobin derivatives and at least one further analyte from the spectrum recorded by the detector device.
