US Patent:

20130202292, Aug 8, 2013

Filed:

Jan 21, 2011

Appl. No.:

13/522520

Inventors:

Vladimir Sokolov - Rochester MN, US
James N. Kruchowski - Rochester MN, US
Mark A. Nelson - Oronoco MN, US
Nathan E. Harff - Rochester MN, US

Assignee:

Mayo Foundation for Medical Education and Research - Rochester MN

International Classification:

H04J 14/02

US Classification:

398 34

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.

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.
