  • Spectrophotometer system and enhanced optical characterization of biological samples using same
    Patent number: 11473976
    Abstract: Spectrophotometer system configured to characterize and/or measure spectrally (wavelength)-dependent properties of material components (such as molecular, viral, and/or bacterial analytes) associated with or of an object prior to the time when optical fingerprints of such material components start to degrade, and associated methods. System can be enhanced by a capability of selecting specific wavelengths of operation for such system to optimize cost-efficiency of the system.
    Type: Grant
    Filed: October 8, 2019
    Date of Patent: October 18, 2022
    Assignee: Mayo Foundation for Medical Education and Research
    Inventors: Daniel J. Schwab, Gary S. Delp, Clifton R. Haider, Barry K. Gilbert, Nathan E. Harff

  • Power recapture in an optical communications system
    Patent number: 8855499
    Abstract: In an n-node optical communications system, energy harvesting photodetectors at each node receive extraneous electromagnetic wavelengths that are not used for communication or other purposes by the associated node. The energy harvesting photodetectors convert the unused electromagnetic energy into reusable electrical energy. The harvested electrical energy may be used as auxiliary power at the node or elsewhere in the communication system, or stored in a battery, capacitor, or other energy storage device. The system may be used in an “all-to-all” broadcast and select communication scheme or in some other broadcast and select interconnect system that has extraneous wavelengths at node receivers.
