Patent number: 9774440Abstract: A full-duplex RF communication system and corresponding methods use digital adaptive filters for interference cancellation. As provided, the techniques allow full-duplex radio frequency communication without frequency-, time-, or code-division multiplexing and without the use of hardware RF cancellers, in real-time. Such techniques may be useful for wireless communication, such a cellular communication, radio communication, broadcasting, short-range point-to-point communication, wireless sensor networks, and wireless computer networks.Type: GrantFiled: November 13, 2015Date of Patent: September 26, 2017Assignee: General Electricity CompanyInventors: Richard Louis Zinser, Michael Joseph Dell'Anno

Patent number: 9678030Abstract: A sensor for detecting gaseous agents has a transducer, which includes an electrical resonant circuit that forms an antenna. The sensor further includes a sensing material that is disposed on at least a portion of the transducer. The sensing material is configured to simultaneously exhibit a capacitance response and a resistance response in the presence of a gaseous agent. The sensor may be reversible, battery free, and may require no electrical contact with a sensor reader.Type: GrantFiled: December 30, 2014Date of Patent: June 13, 2017Assignee: General Electricity CompanyInventors: Radislav Alexandrovich Potyrailo, Zhexiong Tang, Brandon Bartling, Nandini Nagraj, Vadim Bromberg

Patent number: 9638653Abstract: Methods and sensors for selective fluid sensing are provided. Each sensor includes a resonant inductor-capacitor-resistor (LCR) sensor that is coated with a sensing material. In order to collect data, an impedance spectrum is acquired over a relatively narrow frequency range, such as the resonant frequency range of the LCR circuit. A multivariate signature may be calculated from the acquired spectrum to discern the presence of certain fluids and/or fluid mixtures. The presence of fluids is detected by measuring the changes in dielectric, dimensional, resistance, charge transfer, and other changes in the properties of the materials employed by observing the changes in the resonant electronic properties of the circuit. By using a mathematical procedure, such as principal components analysis (PCA) and others, multiple fluids and mixtures can be detected in the presence of one another, even in a high humidity environment or an environment wherein one or more fluids has a substantially higher concentration (e.g.Type: GrantFiled: May 12, 2015Date of Patent: May 2, 2017Assignee: General Electricity CompanyInventors: Radislav Alexandrovich Potyrailo, Cheryl Margaret Surman, Andrew Arthur Paul Burns, Nandini Nagraj
