  • Patent number: 11371944
    Abstract: Embodiments of the present invention encompass systems and methods for detecting the presence of a test pad on a test strip. Exemplary techniques involve receiving a test strip having at least one test pad, where individual test pads have a pad width with ink disposed on two ink zones at two opposing sides of the width of the pad, illuminating the at least one test pad with a light source, detecting reflected signals from the test pad, generating an image comprising of pixels of the two ink zones based on the reflected signals, detecting the presence of each of the ink zones by comparing the number of consecutive pixels against a predetermined threshold, and determining the presence of the test pad on the test strip if two ink zones are detected within the pad width.

  • Publication number: 20180196070
    Abstract: Embodiments of the present invention encompass automated systems and methods for analyzing immature platelet parameters in an individual based on a biological sample obtained from blood of the individual. Exemplary techniques involve correlating aspects of direct current (DC) impedance, radiofrequency (RF) conductivity, and/or light measurement data obtained from the biological sample with an evaluation of immature platelet conditions in the individual.

  • Patent number: 6778910
    Abstract: A signal processing operator successfully expands the dynamic range of a histogram of digital data, such as that representative of biological cell populations, including human blood cells subjected to flow cytometry processing, without introducing binning artifacts into the transformed data. The inventive data mapping scheme effectively preserves statistical probability distribution characteristics of the original data, that would otherwise be removed or lost in the course of expanding the dynamic range of a quantized histogram data set through the use of a conventional log transformation. Filtering is unnecessary, as the binning effect is countered early in the process, to preserve statistical properties of the cell populations under study.
