Abstract

The present disclosure generally pertains to systems and methods for processing optical signals. In some embodiments, an optical system has an optical device for receiving a plurality of optical signals and processing such signals in a desired way. The optical device has one or more functional layers that are separated by buffer layers. The index of refraction of at various points in each functional layer is controlled during manufacturing so that the functional layer performs one or more optical functions or, in other words, manipulates one or more incoming optical signals in a desired way, such as switching, filtering, splitting, focusing, collimating, etc. As an example, the index of refraction profile within a region of a functional layer may be controlled so that an incoming signal from a first optical fiber is redirected for reception by a second optical fiber that is not aligned with the first optical fiber.

Abstract

The present disclosure is directed to method of treating water/wastewater using a plasmon-enhanced catalytic ozonation process. Water/wastewater often contains numerous pollutants, some of which are particularly difficult and inefficient to remove and require energy-intensive treatment such as advanced oxidation processes. The present plasmonic metal nanostructured catalyst is configured to interact with electromagnetic radiation through excitation of localized surface plasmon resonance, leading to accelerated ozone decomposition and reactive species generation. The reactive species oxidizes water pollutants, resulting in a water treatment process that avoids excessive energy input and creation of toxic byproducts. In an exemplary application of the plasmon-enhanced catalytic ozonation process, the atrazine degradation rate is increased compared to conventional ozonation and catalytic ozonation processes, owing to the plasmonic effects of Ag in the plasmonic metal nanostructured catalyst.

Abstract

A system for performing sanitization of multi-level cell (MLC) memory has a memory controller configured to read and buffer at least a first page of MLC memory that shares MLCs with at least a second page. The memory controller sanitizes the second page by performing at least one write operation to adjust the charge levels in the MLCs so that each bit of the second page is forced to the same value or to a value that mirrors the value of another bit of the same cell. Thus, for multiple pages sharing the same MLCs, the data of at least one page can be sanitized while the data of at least one other page is retained. Such sanitizing can be achieved without having to perform an erase operation, thereby helping to prevent or reduce memory degradation.

Abstract

A system for improving radiation tolerance of memory senses an amount of radiation exposure and, based on the sensed amount of radiation exposure, determines whether to perform one or more techniques for mitigating the effects of the radiation exposure. As an example, the system may perform a data refresh operation by re-writing data that has been corrupted by radiation, or the system may adjust the reference voltage used to read memory cells. In another example, the system may perform a fault repair operation by re-programming cells that have erroneously transitioned from a program state to an erase state. The system may selectively perform different radiation-mitigation techniques in a tiered approach based on the sensed amount of radiation in order to limit the adverse effects of the more invasive techniques.

Abstract

An intrusion prevention system can be embedded in an industrial controller to detect possible attacks on the corresponding physical system of the industrial controller. The intrusion prevention system can analyze the payload of network packets received at the industrial controller and predict what harm the payload of the network packet could cause to the physical system if executed by the industrial controller. To predict how the payload of a network packet may affect the physical system, the intrusion prevention system can perform a simulation with the payload of the network packet. The simulation can incorporate a model of the physical system, a copy of the logic used by the industrial controller and information relating to the current state of the system. The result of the simulation can be new predicted states for the physical system that can be evaluated to determine if a safety violation has occurred.

Abstract

A system for using wireless signals to detect objects of a certain type, such as concealed weapons, leverages the fact that different objects have different resonance characteristics. The system transmits wireless signals of different frequencies, and returns from such signals are measured. The return of a signal from an object at a resonant frequency of the object will be stronger than a return of a signal from the object at a non-resonant frequency. The system analyzes the returns in an effort to determine when a return is sufficiently large to indicate that it was reflected from an object of interest. When an object of interest is detected, the system adjusts a characteristic of the system, such as antenna orientation or pulse shape, based on an estimated location of the object, and then runs a test to confirm the detection of the object, thereby eliminating at least some false positives.

The sensors may be configured to detect the shadows, and a controller may be configured to determine any of a variety of information about the passing vehicles based on the detected shadows. For example, the controller may count the number of vehicles that pass, determine a speed of each passing vehicle, and determine a length of each passing vehicle. The sensors can be relatively inexpensive so that a relatively large number of sensors can be used to monitor a large area at a relatively low cost. In some embodiments, solar cells are used to power the sensors, and if desired, the solar cells may be used as the sensors for detecting the shadows of the vehicles being monitored.

Abstract

A battery storage system is configured to store batteries in a safe manner that reduces the threat of thermal runaway. Batteries held by the system are electrically connected to at least one load that is powered by energy from the batteries, thereby depleting the charge level of the batteries. In some embodiments, the load is a temperature control device that is configured to cool the batteries to help prevent a thermal runaway condition during storage. That is, discharging of the battery helps not only to reduce the charge levels in the batteries, thereby decreasing the likelihood of an occurrence of thermal runaway, but also cool the batteries further decreasing the likelihood of such an occurrence. Thus, over time, the battery storage system efficiently controls the charge levels and temperatures of the batteries so that a thermal runaway condition is unlikely.

Abstract

The present disclosure relates to methods of detecting manganese in a solution using resacetophenone oxime by spectrophotometric analysis wherein the resacetophenone oxime produces colorimetric responses to indicate the presence of manganese. The resacetophenone oxime is not only stable in solution, but it also may be inserted into a hydrocolloid gel to facilitate a “spot test” for the detection of manganese, resulting in a long shelf life. These manganese testing methods disclosed herein may be used at the pre-disinfection process at water treatment facilities. The disclosed methods of manganese testing may be combined with an ammoniacal buffer reagent that may be used by water processing facilities, prior to final disinfection, to augment existing manganese (II) efforts of removal. A secondary flocculation with this buffer will scavenge additional manganese (II), that can then be removed by sedimentation or filtration.

Abstract

A system performs analog memory sanitization by forcing voltage levels in memory cells to substantially the same voltage level so that they are indistinguishable regardless of the data that has been previously stored in the cells. In some embodiments, a special programming operation for sanitizing a plurality of memory cells forces the charge in the cells to approximately the same voltage level by increasing the voltage level of all cells regardless of the data currently stored in the cells. As an example, each cell may be programmed to a logical high bit value (e.g., a “0”) by increasing the charge in each cell to a voltage level that is greater than the voltage level for writing the same logical bit value in a normal programming operation. Thus, after the programming operation is performed, the voltage levels of cells storing one logical bit value (e.g., a “0”) prior to the programming operation may be indistinguishable from voltage levels of cells storing a different logical bit value (e.g., a “1”) prior to the programming operation.

Abstract

A rotational swing system is used for providing vestibular stimulation. The rotational swing system may include a rotational swing that is actuated by a motor. The system has a support frame arranged so that the motor does not need to bear the weight of the swing, thereby reducing the cost of the motor. When the system is used in a classroom to provide vestibular stimulation to a child with Autism Spectrum Disorder (ASD), the automatic actuation of the swing by the motor helps to free the teacher's attention for addressing the needs of the other children in the classroom.

Abstract

The present disclosure is generally directed to a method of curing an ionic liquid epoxy mixture using an electromagnetic signal. First, an ionic liquid epoxy resin comprising ionic liquid epoxide monomers and, optionally, diluent epoxy resins and powdered fillers, is combined with a curing agent to form an ionic liquid epoxy mixture. The mixture is then applied as a coating onto a surface of a material. The coating is placed in contact with a second surface of the same material or a surface of another material. An electromagnetic signal, which in some instances is a microwave signal, is applied to the coating. Following application of the signal, the ionic liquid epoxide monomers polymerize and the mixture cures, adhering the surfaces together. Alternately, the epoxy mixture is applied to a surface and cured with microwaves to form a protective coating as in cladding or paint.

Abstract

The present disclosure generally pertains to systems and methods that utilize optical frequency discriminators based on fiber Bragg gratings. In some embodiments, an optical frequency discriminator has a polarization-maintaining fiber Bragg grating (PM-FBG), and an incoming polarized optical signal is reflected from the PM-FBG, which differentiates the two polarization modes in the incoming signal according its frequency relative to the two resonance peaks of the PM-FBG. The optical frequency discriminator then compares (e.g., subtracts) the reflected power in the two polarization modes to provide an output having an amplitude that varies linearly with the frequency of the incoming signal. This output may then be used to extract various information about the frequency of the incoming signal. As an example, the output may be used to recover data that has been frequency modulated onto the incoming signal or to characterize the frequency noise of the incoming signal.

Abstract

A weather forecasting system has weather forecasting logic that receives weather data from a satellite or other source, such as radar. The weather forecasting logic processes such data to identify cumulus clouds. For each cumulus cloud identified, the weather forecasting logic applies interest field tests and feeds the results into formulas derived based on measurements from current and past weather events. The model determines a score indicating the likelihood of the cumulus cloud forming precipitation and a score indicating the likelihood of the cumulus cloud forming lightning in the future within a certain time period. Based on such scores, the weather forecasting logic predicts in which geographic regions the identified cumulus cloud will produce precipitation and/or lightning during the time period. The predictions of the weather forecasting logic may then be used to provide a weather map thereby providing users with a graphical illustration of the areas.

Abstract

A time-wavelength optical sampling system may be configured to determine a substance's composition based on variations in optical pulses caused by the substance's absorption of wavelengths of the pulse. A dispersion medium may disperse pulses to form stretched signal pulses that are incident on a substance under test. Optical gating is used to overlap each signal pulse with a portion of a reference pulse to generate a cross-correlation signal corresponding to a portion of the signal pulse, which may be detected by a slow detection speed detector. A controller controls delay introduced to the reference pulses so that different wavelength ranges are sampled for various signal pulses, thereby enabling the entire wavelength range for the signal pulses to be sampled over time without requiring an expensive high-speed optical detector. By analyzing absorption across the entire wavelength range as indicated by cross-correlation signals, the composition of the substance can be identified.

Abstract

A coupling system can include an energy transfer device and a load mitigation system.

The load mitigation system can dampen both resonant loads and impulsive impact loads occurring at the object thereby preventing damage and extending life.

Abstract

A system for testing memory includes logic that is configured to perform various normal memory operations (e.g., erase, read and write operations) on a memory device and to determine operational parameters associated with the memory operations. As an example, the amount of time to perform one or more memory operations may be measured, or a number of errors resulting from the memory operations may be counted or otherwise determined. One or more of the operational parameters may then be analyzed to determine whether they are in a range expected for counterfeit memory. If so, the logic determines that the memory under test is counterfeit (e.g., is recycled or counterfeit) and provides a notification about the authenticity of the memory. The logic may also estimate the age of the memory based on the operational parameters.

Abstract

Due to design variations, process variations, manufacturing variations, and other factors, memory of a certain type manufactured by one manufacturer often exhibits a unique pattern of performance characteristics relative to the patterns of the same type of performance characteristics exhibited by memory from other manufacturers. A system for identifying counterfeit memory is trained to learn the different patterns of performance characteristics for different manufacturers of memory. Thereafter, the system may analyze the performance of a given memory device to determine whether the memory device has been manufactured by a particular manufacturer. Thus, the system is capable of determining whether the memory device is counterfeit (e.g., has been manufactured by an unexpected manufacturer).

The micro-lenses may focus optical signals from the optical fibers to create an approximately collimated optical path for the optical signals, reducing optical spread and enhancing fiber-to-fiber optical power coupling.

Abstract

A weather forecasting system may receive satellite image samples and identify an updraft and components of the updraft within a cloud. These satellite image samples are collected over time (e.g., at 30 second to 1 minute time intervals). The system may identify an area of rotation and/or divergence at cloud top in a cumulus cloud or mature convective storm over time by comparing the samples and determine a parameter indicative of the updraft based on the area of rotation and divergence. The system may estimate aspects of the environment related to storm development and predict the occurrence of a weather event in the future based on the parameter and generate an output indicative of the occurrence.

Abstract

A weather forecasting system has a data processing system that receives weather data from one or more sources and processes such data in conjunction with a weather forecasting algorithm in order to forecast weather for one or more geographic regions. In this regard, the weather data is input into a machine learning algorithm, which applies learned weights and relationships to the inputs in order to calculate at least one score indicating a probability that precipitation or other weather event will occur in the future within a certain time period (e.g., within the next 1 hour or some other unit of time) in one or more geographic regions. For each such geographic region, the weather forecasting logic may also predict the extent to which rain or other precipitation, lightning, or other weather event will occur during the time period.

Abstract

The present disclosure is generally directed to methods and systems for the rapid detection of mycobacteria in samples using lectin-conjugated silica coated magnetic nanoparticles (SMNPs). In this work, carbohydrates on the cell wall of the mycobacteria serve as binding sites for lectins conjugated on the surface of lectin-conjugated SMNPs. As the target species of mycobacteria bind to lectin-conjugated SMNPs, a precipitate forms, which can be magnetically separated from the bulk test solution to visually indicate the presence of the target species of mycobacteria. The present disclosure is utilized as an inexpensive and rapid point of care system in one embodiment. In another embodiment, the methods and systems are integrated into a lateral flow assay for rapid detection of the target species of mycobacteria. In yet another embodiment, the methods and systems are utilized to create a microfluidic detection device with increased sensitivity to mycobacteria in a sample.

Abstract

Systems and methods are provided to implement moving target defense techniques for transportation systems. The moving target defense techniques can randomly change the IP addresses of the nodes associated with both the vehicles and the corresponding control centers. The nodes for the vehicles and the control centers can be “mobile” nodes that use a “care-of” IP address for communications. The care-of address used by the nodes can be updated through a binding update process. During the binding update process, the one node sends the binding update notice (with a new care-of address) to the care-of address of the other node while maintaining its prior care-of address. The node that receives the binding update notice can send a binding acknowledgement back to the node that sent the binding update. Once the binding acknowledgement is received, the prior care-of address can be removed by the node that sent the binding update.

Abstract

A reflection optical filter has an ultra-thin semi-transparent layer and a thin layer of semiconductor (or dielectric) layer deposited onto a metal film surface at a certain thickness corresponding to a wavelength of light to be filtered from incoming light. Critical coupling of light to the optical cavity formed by the semi-transparent layer and semiconductor (or dielectric) layer on metal surface results in near perfect absorption of the light at one wavelength and strong absorption in the wavelength region near the peak absorption wavelength. Incoming lights of other wavelengths are mostly reflected by the device so the spectral content of incident light is changed. By controlling the thickness of the semiconductor (or dielectric) layer and/or other factors, such as the extent to which the semiconductor layer is annealed or changing the type of metal beneath the semiconductor (or dielectric) layer, the peak absorption wavelength of the light absorbed in the device can be precisely controlled. The overall thickness of the semi-transparent layer and semiconductor (or dielectric) layer is less than one order of magnitude of the wavelength to be filtered, which results in omni-directional performance of the optical filter.

Abstract

The present invention relates to a method for the continuous production of low thermal conductivity endless filament yarns with a compact, homogeneous structural morphology. The presently disclosed methods utilize safe and recyclable ionic liquids to produce carbon fiber precursors from cellulose. The fibers are produced by the carbonization of cellulose carbon fiber precursors. The precursor fiber filaments have an increased tear resistance with simultaneously sufficient elongation, a round or crenulated cross-section, and homogeneous fiber morphology. The filament yarns exhibit performance characteristics similar to those produced from traditional viscose rayon. The resulting fibers are especially suited for aerospace applications in composite materials used at the limits of high temperatures, for instance in structures found in rocket nozzles or atmospheric reentry heat shields on spacecraft.

Abstract

An optical filter has a layer of silicon film deposited onto a metallic substrate surface at a silicon film thickness corresponding to a wavelength of light to be filtered from incoming light. The critical coupling of light to the optical cavity formed by the silicon film on metal surface results in a strong and near perfect absorption of the light at a resonance wavelength and strong absorption in the wavelength region near the peak absorption wavelength. Other wavelengths of the incoming wave are reflected by the device so the spectral content of light is changed. By controlling the thickness of the silicon film and/or other factors, such as the extent to which the silicon film is annealed or the type of metal beneath the silicon film, the wavelength of the light absorbed by the silicon film can be precisely controlled.

Abstract

A cutting blade for use in a lawnmower or other cutting device has a contoured leading edge profile that forms a series of protrusions and contoured notches. Each contoured notch has a surface that is smooth and contoured such that air is funneled through the contoured notch by the adjacent protrusions, thereby causing the air to form vortices at the surface of the blade. The formation of the vortices helps the airflow to adhere to the blade surface rather than separate from it, thereby creating a more laminar streamlined flow that merges with air flowing over the opposite side of the blade at the trailing edge. By preventing the airflow from separating from the blade surface over a substantial portion of the blade, turbulence is significantly reduced. Thus, noise generated by the blade is significantly reduced as well. In addition, the blade experiences less drag, and the performance of the blade and lawnmower is generally increased.

Abstract

The present disclosure pertains to metal or dielectric nanostructures of the subwavelength scale within the grating lines of optical diffraction gratings. The nanostructures have surface plasmon resonances or non-plasmon optical resonances. A linear photodetector array is used to capture the resonance spectra from one of the diffraction orders. The combined nanostructure super-grating and photodetector array eliminates the use of external optical spectrometers for measuring surface plasmon or optical resonance frequency shift caused by the presence of chemical and biological agents. The nanostructure super-gratings can be used for building integrated surface enhanced Raman scattering (SERS) spectrometers. The nanostructures within the diffraction grating lines enhance Raman scattering signal light while the diffraction grating pattern of the nanostructures diffracts Raman scattering light to different directions of propagation according to their wavelengths. Therefore, the nanostructure super-gratings allows for the use of a photodetector array to capture the surface enhanced Raman scattering spectra.

A system in accordance with an exemplary embodiment of the present disclosure comprises an optical fiber having a metallic dot array on a tip of the optical fiber, a light source coupled to the optical fiber via a light coupler, and a spectrometer coupled to the optical fiber via the coupler. The light source is configured to transmit light within a range of wavelengths along the optical fiber. When the light reaches the dot array, the light excites surface plasmons of the dot array and causes the surface plasmons of the dots to resonate. The dots are chemically functionalized to have a specific affinity for a particular substance, and the resonance frequency of the dots changes when the substance is present thereby changing an absorption peak of the light. The light is reflected back through the optical fiber to the spectrometer, and the spectrometer detects a parameter indicative of a change in the absorption peak. Presence of the particular substance is determined based upon the change in the absorption peak.

Abstract

A camera concurrently produces an orthographic map and map spectral content. Illumination from an image passes through a phase modulator and the resulting rotating photo-flux phase is converted to an electrical signal by multiple adjacent sensors of detectors of array of detectors. The amount of unwanted illumination reaching the sensors is reduced by a set of baffles that shield and protect the transducers from unwanted out-of-field light and other light sources.

Abstract

A weather forecasting system has weather forecasting logic that receives raw image data from a satellite. The raw image data has values indicative of light and radiance data from the Earth as measured by the satellite, and the weather forecasting logic processes such data to identify cumulus clouds within the satellite images. For each identified cumulus cloud, the weather forecasting logic applies interest field tests to determine a score indicating the likelihood of the cumulus cloud forming precipitation and/or lightning in the future within a certain time period. Based on such scores, the weather forecasting logic predicts in which geographic regions the identified cumulus clouds will produce precipitation and/or lighting within during the time period. Such predictions may then be used to provide a weather map thereby providing users with a graphical illustration of the areas predicted to be affected by precipitation within the time period.

Abstract

The present disclosure pertains to metal or dielectric nanostructures of the subwavelength scale within the grating lines of optical diffraction gratings. The nanostructures have surface plasmon resonances or non-plasmon optical resonances. A linear photodetector array is used to capture the resonance spectra from one of the diffraction orders. The combined nanostructure super-grating and photodetector array eliminates the use of external optical spectrometers for measuring surface plasmon or optical resonance frequency shift caused by the presence of chemical and biological agents. The nanostructure super-gratings can be used for building integrated surface enhanced Raman scattering (SERS) spectrometers. The nanostructures within the diffraction grating lines enhance Raman scattering signal light while the diffraction grating pattern of the nanostructures diffracts Raman scattering light to different directions of propagation according to their wavelengths. Therefore, the nanostructure super-gratings allows for the use of a photodetector array to capture the surface enhanced Raman scattering spectra.

Abstract

The present disclosure generally pertains to systems and methods for drug compliance monitoring. A drug compliance monitoring system in accordance with one exemplary embodiment of the present disclosure comprises a portable drug containment unit, which has a drug container, such as a pill bottle, for holding prescription or non-prescription drugs. The drug containment unit also comprises at least one sensor and control logic. The sensor is configured to automatically sense a parameter indicating when a drug, such as one or more pills or an amount of liquid, has been or is about to be removed from the drug container. The system, based on the sensor, automatically estimates and tracks drug consumption and provides a patient with reminders when a dosage is currently due. If the patient deviates from an expected drug regime, the system automatically senses this event and provides a notification to the patient or caregiver. In addition, the system stores a usage history indicating the approximate time and amount of each sensed dosage.
