摘要： A state detection device capable of detecting a state of an apparatus is provided. A state detection device includes an acquisition unit that acquires observation information including information regarding a resonance frequency of microwaves acquired by introducing microwaves into a first apparatus, which is the target of state detection, while sweeping the frequency; a detection unit that detects the state of the first apparatus by comparing the observation information with reference information including information regarding a resonance frequency of microwaves introduced into a second apparatus in a reference state; and an output unit that performs output in accordance with a detection result of the detection unit.

摘要： The disclosed method involves using a radio frequency sensor to estimate soot load in a diesel particulate filter. An engine control module receives a first mean attenuation value derived from attenuation values for a set of radio frequencies within a specific band detected by the sensor. Additionally, first standard deviation data related to the mean attenuation value is received. The method determines whether this standard deviation data exceeds a predefined threshold. If not, the first mean attenuation value is used to infer the soot load. If the standard deviation data threshold is exceeded, a second mean attenuation value from a different set of radio frequencies within another band is obtained. Similarly, second standard deviation data is received. If the second standard deviation data does not exceed the threshold, the second mean attenuation value is used to infer the soot load.

摘要： Techniques are provided for sensing, detecting, characterizing, and imaging dielectric objects using microwave signals. An example of a method for obtaining an image with a dielectric tomography system includes positioning an object in at least a portion of an electromagnetic field of a characterized sensor including at least one transmit antenna configured to transmit a radio frequency signal within 10 MHz and 300 GHz, positioning one or more receive antennas configured to receive one or more radio frequency signals scattered by the object, determining permittivity information associated with the object based at least in part on phase and magnitude measurements of the one or more radio frequency signals received by the one or more receive antennas, and computing one or more images based on the permittivity information and calibration information associated with the characterized sensor.

摘要： Globally our environment comprises structures built to perform a meet different requirements including residential, commercial, retail, recreational and service infrastructure. Whilst, millions of tons of construction materials are deployed annually the quality control procedures in many instances have not changed to reflect today's demands. Accordingly, it would be beneficial to provide construction companies, engineering companies, infrastructure owners, regulators, etc. with means to automated testing/characterization of construction materials during at least one of its manufacture, deployment in construction and subsequent infrastructure life. It would be further beneficial for such automated methods to exploit self-contained data acquisition/logging modules allowing them to be employed with ease at the different points in the life cycle of a construction material and/or construction project.

摘要： Apparatus, systems and methods of analyzing an in vitro flowing fluid using an in vitro sensor that operates using non-optical frequencies such as in the radio or microwave frequency bands of the electromagnetic spectrum. The in vitro sensor directs one or more signals that are in the radio or microwave frequency bands of the electromagnetic spectrum into an in vitro flowing fluid and detects one or more responses that result from transmission of the signal(s) into the in vitro flowing fluid.

摘要： Methods and systems for RF pulse monitoring and RF pulsing parameter optimization at a manufacturing system are provided. Sensor data is received from one or more sensors that indicates an RF pulse waveform detected within the processing chamber. One or more RF signal characteristics are identified in the detected RF pulse waveform. Each identified RF signal characteristic corresponds to at least one RF signal pulse of the RF signal pulsing within the processing chamber. A determination is made, based on the identified one or more RF signal characteristics, whether the detected RF pulse waveform corresponds to the target RF pulse waveform. An indication of whether the detected RF pulse waveform corresponds to the target RF pulse waveform is provided to a client device.

摘要： A method and a system for detecting microwave signals which carry information of the functional dynamics of biological particles are provided. The method comprises illuminating a biological particle with microwave electromagnetic waves, the microwave electromagnetic waves being comprised in a non-thermal intensity regime, having frequencies with wavelengths much larger than characteristic dimensions of the biological particle and being adapted to a functional dynamics signature of the biological particle; adapting the illuminating microwave electromagnetic waves to produce additional frequencies by an upconversion parametric process of frequency mixing in the vicinity of a membrane of the biological particle with a nonlinear relationship; capturing a response affected by the nonlinear relationship at different functional states of the biological particle; and detecting resulting frequency components of the captured response by means of a filtering element, so as to thereby infer the functional dynamics of the biological particle.
