Patent number: 9515729Abstract: A free space optical receiver comprising a photodetector and a fiber bundle. The fiber bundle comprises a plurality of optical fibers splayed apart at one of their ends to receive free space optical energy from multiple directions. The splayed apart ends of the plurality of optical fibers may create a hemispherical shape. Each of the plurality of optical fibers has an acceptance cone for which it couples optical energy into the splayed end of the optical fiber. The acceptance cones of the splayed ends of the plurality of optical fibers may overlap to form an omnidirectional acceptance zone. The other, non-splayed ends of the plurality of optical fibers are communicatively coupled to the photodetector, which is positioned to receive the free space optical energy from the non-splayed ends of the plurality of optical fibers. An optical communication system including the free space optical receiver is also described.Type: GrantFiled: April 29, 2015Date of Patent: December 6, 2016Assignee: Florida Institute of Technology, Inc.Inventors: Syed H.

Publication number: 20160251343Abstract: A photoacid includes a nucleophilic (NuH) moiety having a photodissociable proton, an electron accepting (EA) moiety, and a bridge structure (X) bonded to both the NuH moiety and EA moiety positioned between the NuH and EA moieties. The NuH and EA moieties each include respective structure so that the EA moiety bonds to a proton photodissociated form of the NuH moiety during a reversible photoinduced intramolecular reaction to form a ring, which has been found to significantly increase the lifetime of the proton dissociation state.Type: ApplicationFiled: March 1, 2016Publication date: September 1, 2016Applicant: Florida Institute of Technology, Inc.Inventor: YI LIAO

Publication number: 20160233959Abstract: A multiplexed optical communication system comprising a carrier optical fiber, a plurality of launching light sources, and a matching plurality of multiplexer/demultiplexers and photodetectors is described and claimed. Optical communication channel separation by Spatial Domain Multiplexing (SDM), Optical Angular Momentum (OAM) multiplexing, and Wavelength Division Multiplexing (WDM) is used in combination to achieve significant increase in optical communication channel bandwidth over the prior art. The launching light sources may be positioned such that the light beams are incident on the receiving end of the carrier optical fiber at desired angles including complementary angles. Crosstalk between optical communication channels is minimal. The communication bandwidth of a TDM system may be increased by an order of magnitude due the layered WDM/SDM/OAM data multiplexing of the invention.Type: ApplicationFiled: February 8, 2016Publication date: August 11, 2016Applicant: Florida Institute of Technology, Inc.Inventors: Syed H.

Patent number: 9394804Abstract: Actuation systems and methods for varying the angle of small turbine engine inlet guide vanes (IGV) and/or compressor stator vanes (CSV). Such systems and methods may employ a piezoelectric inchworm actuator (or a piezo stack actuator or magnetostrictive actuator, depending upon actuation requirements) to actively modify the angle of attack of a single or a cascade of inlet guide vanes or compressor stator vanes. The change in angle of attack is necessary due to large variations in engine operating envelope including but not limited to air density, velocity, temperature, and the like. The present invention is especially suitable to actuate small inlet guide vanes and compressor stator vanes found in small turbine jet engines including but not limited to those under ten (10) inches in diameter.Type: GrantFiled: January 24, 2013Date of Patent: July 19, 2016Assignee: Florida Institute of TechnologyInventor: Razvan Rusovici

Publication number: 20160068240Abstract: A vertically rotating grooming attachment brush comprising a brush hub and bristles, and method for cleaning a surface having organic biofouling. The bristles extend from the brush hub and are positioned at or near its outer rim. One or more rows of bristles can be included. The bristles can be grooming bristles or shroud bristles or a combination of the two. A rigid or elastomeric shroud or skirt can also be included about the edge of the brush hub. Vertical rotation of the grooming attachment brush causes a low pressure region to build in the central area of the brush hub. This low pressure region creates a force that forcefully attracts the grooming attachment brush to the surface to be cleaned.Type: ApplicationFiled: September 4, 2015Publication date: March 10, 2016Applicant: FLORIDA INSTITUTE OF TECHNOLOGY, INC.Inventors: Geoffrey Swain, Michael Harper, Abraham Stephens, Melissa Tribou

Patent number: 8307429Abstract: A method of determining that protected software is running in a virtualized environment includes obtaining a set of baseline measurements of system call timings in native operating system environments. Statistical thresholds are established based on the baseline measurements such that there is a predetermined probability that protected software running in a native environment will experience system call durations that exceed the thresholds. The protected software is analyzed and instructions are incorporated within the software such that particular system calls, demonstrated to be differentiating using the set of baseline measurements and the threshold analysis, are executed during the normal running of the protected software. The incorporated instructions are used to estimate the parameter values that are to be compared with the established statistical thresholds.Type: GrantFiled: August 7, 2007Date of Patent: November 6, 2012Assignee: Florida Institute of TechnologyInventors: Richard Ford, William Allen, Gerald Marin
