  • Patent number: 9287599
    Abstract: Described is a miniature tunable filter, comprising at least two adjacent coaxial-type resonators coupled to one another. Each coaxial-type resonator comprises a metal-coated ceramic dielectric cavity having a tuning rod passage formed therethrough. A tuning rod is inserted through the tuning rod passage, such that the miniature tunable filter is tuned by moving the tuning rod into and out of the tuning rod passage of the ceramic dielectric cavity. A low impedance coaxial section surrounds at least a portion of the tuning rod to create an effective microwave short-circuit at a resonant frequency of the miniature tunable filter, which results in very wide tuning and low insertion loss. In a desired aspect, the tuning rod is a solid metal tuning rod. The combination of a solid metal tuning rod with a ceramic coaxial-type resonator results in high radio frequency power handling.

  • Patent number: 9103261
    Abstract: A device and method for adjusting dosage of a fuel additive is described. The device includes a fuel reservoir and an additive reservoir. A variable-flow pump is used to pump the additive into contact with the fuel to create a combined fluid. An ESR sensor is positioned downstream from the pump and fuel reservoir such that a portion of the combined fluid passes through the ESR sensor, which measures the concentration of contaminants and fuel additive in the fuel. Based on the concentrations, a controller controls the rate at which the fuel additive is pumped, thereby adjusting the dosage of the fuel additive.

  • Patent number: 8648596
    Abstract: Described is an electron spin resonance (ESR) spectrometer comprising a miniaturized radio-frequency (RF) microwave cavity resonator. The miniaturized RF microwave cavity resonator receives a carrier signal from a circulator, modulates the signal path signal, and reflects the carrier signal back to the circulator to amplify the carrier signal prior to demodulation. A mixer receives and demodulates the carrier signal and outputs an audio signal to generate an ESR spectrum for analyzing a chemical composition of a fluid sample. The ESR spectrum represents a magnetic susceptibility of the fluid sample to a magnetic resonance cause variation in a resonant frequency of the miniaturized RF microwave cavity resonator. In a desired aspect, the carrier signal is split into two paths prior to demodulation. The two paths are demodulated by different mixers to produce two separate outputs, an absorption spectrum and a dispersion spectrum.
