Abstract: Methods and sensors for the detection, identification, and quantification of one or more gas species, including volatile organic compounds, in a test sample are described. Methods employ gas sensors comprising a diffusion matrix present on the sensor surface. A gas analyte in a test sample diffuses through the matrix and is detected upon interaction of the analyte with the sensor. A response profile of a gas sensor to a gas analyte in the test sample is compared to a control gas sensor response profile determined in a similar manner for a known gas species. Comparisons of test sample and control sample sensor response profiles enable detection, identification, and quantification of a gas species analyte in a test sample.

Abstract: A light field relay has an array of microlenses, an array of transducers, and an array of output optics. Microlenses focus one or more than one selected portions of an incident light field to separate corresponding transducers. Each corresponding transducer receives and transduces a single portion of focused light and emits the transduced light. Corresponding different output optics substantially collimate the transduced light and emit the substantially collimated light as an emitted light field. The light field relay may collect infrared light in one or more selected portions of an incident light field, transduce the infrared light to visible light, substantially collimate the transduced visible light, and emit a visible light field.

Abstract: Techniques are disclosed relating to thread preemption in the context of memory-backed registers. In some embodiments, a memory hierarchy includes one or more cache levels and one or more memory circuits. Execution circuitry may operate on operands in architectural registers to execute instructions of threads, where data for the architectural registers is stored and backed by the memory hierarchy. Control circuitry may, in response to a context switch indication for a given thread: flush and invalidate a set of architectural register data from a first cache level and store memory page information (e.g., a page catalog base address) associated with the set of architectural register data.

Abstract: A method and apparatuses to extend the time interval between out-of-service, in-tank inspections while insuring structural integrity using a risk-based, Bayesian statistical approach comprised of a passing leak detection test, determining that the tank is not leaking, estimating a thickness of the tank floor to estimate a corrosion rate, and conducting a risk assessment using the result of the leak detection test, the corrosion rate and thickness of the tank floor, and statistical data of tank failures.

Abstract: An apparatus comprises a housing defining a chamber that has a liquid disposed therein, and a sensor submerged in the liquid. The sensor comprises a porous conductive film on a substrate, and the film comprises chemiresistive semiconducting metal oxide structures. The sensor also comprises an electrode pair operably connected to the porous conductive film for generating electric current in the film and for detecting a change in an electrical property of the film. The apparatus can be used to detect, identify, and quantify ions and molecules in a liquid sample. Molecules and ions, in a liquid sample, that interact with the porous conductive film can cause a change in an electrical property of the film. The change in electrical property of the film can be correlated with the presence and amount of the molecules or ions.

Abstract: The method and apparatus of the present invention will provide a means for a tank owner to determine the time until the next out-of-service API 653 internal inspection of an aboveground storage tank (AST) or an underground storage tank (UST) should be considered or performed based on in-service measurements of the tank filled with fuel or another liquid. The inspection interval is determined from a leak detection test with a pass and a probability distribution of the survival rate of the tank bottom that is representative of the tank being inspected. More accurate estimates are obtained by using measurements of the thickness and corrosion rate of the tank bottom at one or a few locations in the tank and the results of an acoustic emission (AE) corrosion activity test and/or previous out-of-service inspection measurements of the tank floor bottom thickness of the floor at many locations. The method is based on the concept of equivalent risk.

Abstract: A tunable notch filter for operation in reflection mode comprises an antenna layer positioned on a transmissive substrate and a mirror layer positioned on a support substrate. The antenna layer and the mirror layer are positioned on opposite sides of a gap and facing each other, the gap having a gap distance. The notch filter is tuned by adjusting the gap distance between the antenna layer and the mirror layer. Tuning the notch filter to a selected state can cause the filter to selectively attenuate the reflection of at least some electromagnetic radiation that is incident on the transmissive substrate and enters the notch filter.

Abstract: A method of mounting a storage unit to a vehicular apparatus, such as a motorcycle, includes the step of securing a cantilevered mounting member having a mounting plate to the frame of the vehicular apparatus. A storage device can be connected to the mounting plate to stabilize the storage device as the vehicular apparatus is in motion. As a preferred embodiment, the method of mounting begins with the removal of a foot peg from a motorcycle to expose the foot peg mounting bracket to which the mounting member is affixed. The mounting plate of the mounting member can be used to secure articles to be transported by the vehicular apparatus with or without a separate storage device.

Abstract: Methods use a tunable notch filter for constructing a spectral map of electromagnetic radiation in a selected spectral band that is incident on a notch filter for a plurality of time periods. Electromagnetic radiation is passed by an electronically tuned notch filter to a detector array for the plurality of selected time periods, and the detector response is determined. For at least a first selected time period the notch filter is tuned to selectively attenuate the passing of one or more selected sub-bands of electromagnetic radiation in the selected spectral band. Information about the selectively attenuated radiation is determined and used along with information about the radiation passed to the detector array for each time period to construct a spectral map. Electronically tunable notch filters may be made with metamaterials such as patterned graphene.
