  • Patent number: 10481145
    Abstract: In one embodiment, a device for measuring blood coagulation includes a substrate having a surface, an optical waveguide provided on the surface of the substrate, the waveguide having a tip, and means for spatially separating objects from the tip of the waveguide.
    Type: Grant
    Filed: February 22, 2016
    Date of Patent: November 19, 2019
    Assignee: University of South Florida
    Inventor: Anna Pyayt
  • Publication number: 20170082602
    Abstract: In one embodiment, an optical spectroscopy probe includes an optical fiber having a distal tip and a microfluidic filtering chamber attached to the distal tip of the optical fiber, the chamber comprising a microfluidic membrane adapted to enable liquid to enter the chamber but prevent particles from entering the chamber.

  • Patent number: 9547899
    Abstract: A system for hemolysis detection, where the system generally includes—individually or in combination—a containment apparatus for holding the blood sample and a software application for analyzing the blood sample. The containment apparatus houses the sample therein, and blocks out any light from penetrating the apparatus and reflecting off of the sample. In conjunction, the software application uses camera color for processing the color of the sample to determine the hemoglobin level in plasma based on the color.

  • Patent number: 8508447
    Abstract: A pixel includes a primary element and a secondary element. At least a portion of the primary element is deformable between two positions. In one position, the light source is reflected such that the observer observes a dark pixel. In the other position, the light is reflected such that the observer observes a bright pixel. Gray levels of light are viewable by varying between the two positions.

  • Patent number: 8390800
    Abstract: An angle sensor, system and method employ a guided-mode resonance. The angle sensor includes a guided-mode resonance (GMR) grating and a resonance processor. The resonance processor determines an angle of incidence of a signal incident on the GMR grating. The resonance processor uses a guided-mode resonance response of the GMR grating to the signal to determine the angle of incidence. The angle sensing system includes the GMR grating, the resonance processor and further includes an optical source that produces the signal. The method includes providing a GMR grating, detecting a guided-mode resonance produced in the GMR grating when subjected to an incident signal, and determining an angle of incidence of the incident signal from one or both of a number of and a spectral distance between guided-mode resonances present in a response of the GMR grating to the incident signal.
