摘要： Infrared sensing systems having improved vibration cancelation, and methods of achieving improved vibration cancelation. In one example, an infrared sensing system includes an infrared sensor configured to produce a sensor output signal representative of a response of the infrared sensor to infrared excitation and vibration excitation, an accelerometer configured to provide an acceleration signal responsive to the vibration excitation, and a controller, including an adaptive digital filter, coupled to the infrared sensor and to the accelerometer, and configured to receive the acceleration signal and to adjust coefficients of the adaptive digital filter so as to minimize coherence between a residual signal and the acceleration signal, the residual signal being a difference between the sensor output signal and a filter output signal from the adaptive digital filter.

摘要： Systems and method herein describe embedding graphs into a semantic multidimensional space by receiving a dataset, constructing a Markov chain from the dataset, the Markov chain comprising a plurality of nodes selecting a basis node and a target node from the plurality of nodes, determining a distance from the target node to the basis node, storing the distance between the target node and the basis node in a vector, analyzing the vector, and determining a semantic characteristic of the target node based on the analysis of the vector.

摘要： A microwave switch. In some embodiments, the microwave switch includes a substrate, a signal conductor, a first ground conductor, on a first side of the signal conductor, and a second ground conductor, on a second side of the signal conductor. The signal conductor, the first ground conductor, and the second ground conductor may be planar conductors on a planar top surface of the substrate. The signal conductor may have a first portion composed of a superconducting material, and a second portion having a reduced cross section, a cross-sectional area of the second portion being less than 120 nm.

摘要： Systems and methods for using auditorily-induced vection (AIV) to enhance a person's attitude awareness are provided herein. In at least one embodiment, an auditory object is projected based on the orientation of the person or a vehicle and the projected auditory is provided to the person. By projecting the auditory object, the attitude of the person or the vehicle can be conveyed to the person to enhance the person's attitude awareness.

摘要： A photon detector including a graphene-insulating-superconducting junction configured as a temperature sensor. Photons are absorbed by the graphene sheet of the graphene-insulating-superconducting junction, each absorbed photon causing a temporary increase in the temperature of the graphene sheet, and a corresponding change in the differential impedance of the graphene-insulating-superconducting junction. The graphene-insulating-superconducting junction is part of a resonant circuit connected as a shunt load between a radio frequency input transmission line and a radio frequency output transmission line. The transmission S-parameter from input to output is affected by the impedance of the resonant circuit which in turn is affected by the differential impedance of the graphene-insulating-superconducting junction, and therefore by the temperature of the graphene sheet. The absorption of photons is detected by detecting changes in the transmission S-parameter indicating temperature changes caused by the absorption of a photon.

摘要： A transistor. In some embodiments, the transistor includes a first superconducting source-drain, a second superconducting source-drain, a graphene channel including at least a portion of a graphene sheet, and a conductive gate. The first superconducting source-drain, the second superconducting source-drain, and the graphene channel together form a Josephson junction having a critical current. The graphene channel forms a current path between the first superconducting source-drain and the second superconducting source-drain. The conductive gate is configured, upon application of a electric field across the conductive gate and the graphene channel by applying a voltage, to modify the critical current.

摘要： A system for covert sensing. A broadband light source is split into two portions, a first portion of which illuminates a target, and a second portion of which is frequency shifted, e.g., by an acousto-optic frequency shifter. Light reflected from the target is combined with the frequency shifted light, detected, and demodulated with an in-phase and quadrature demodulator. The outputs of the demodulator are filtered and the arc tangent of the ratio is calculated.

摘要： A method for performing security functions in a computer system hosting a network-facing server application includes receiving, by a service request processor, a service request to an application adapted to process the service request; responsive to the service request being a first request for the application to communicate over a network, processing the service request with a first process isolated in memory from the application; responsive to the service request being a second request for the application to access a physical storage device, processing the service request with a second process isolated in memory from the application; and responsive to a determination that the processed service request will not adversely affect the application, providing the processed service request to the application.

摘要： An SDR system and method that intentionally illuminates aircraft systems with RF energy having specific characteristics (e.g., frequency, power, waveform, directionality, duration, etc.) are provided. The aircraft systems act as non-linear mixers and emit non-linear RF energy. A receiver receives the RF energy response and generates an RF energy representation that is correlated to a database of baseline responses. A correlation response between the received RF energy representation and any one of the baseline responses from the database provides an indication of the aircraft system status.
