Abstract: Embodiments disclosed herein include a sensor apparatus that includes a gas cell-body with a first end and a second end, and a light source coupled to the first end of the gas cell-body, where the light source is configured to emit electromagnetic radiation through the gas cell-body. In an embodiment, the sensor apparatus further includes a photonic detector system coupled to the second end of the gas cell-body, and a housing around the gas cell-body that is temperature controlled, where the photonic detector is outside the housing. The sensor apparatus may further include a temperature sensor configured to measure a temperature of the photonic detector system or a temperature of the gas cell-body.

Abstract: In embodiments disclosed herein, a method for calibrating a photonic sensor includes collecting a plurality of concentration measurements with a photonic sensor with a plurality of different reference gas mixtures under various temperature and pressure environments, where each reference gas mixture includes a known species concentration, and implementing a parameter optimization routine to minimize deviations between the known species concentrations and the plurality of concentration measurements obtained by the photonic sensor, where the optimization routine generates one or more calibration constants. In an embodiment, the method may further include integrating the one or more calibration constants into a modified concentration formula, and storing the modified concentration formula in a controller used to operate the photonic sensor.

Abstract: A power supply control system includes a power generator for providing a signal to a load. The power generator includes a power controller controlling a power amplifier. The power generator includes an adaptive controller for varying the output signal controlling the power amplifier. The adaptive controller compares an error between a measured output and a predicted output to determine adaptive values applied to the power controller. The power generator also includes a sensor that generates an output signal that is digitized and processed. The sensor signal is mixed with a constant K. The constant K is varied to vary the processing of the sensor output signal. The value K may be commutated based on the phase, frequency, or both phase and frequency, and the bandwidth of K is determined by coupled power in the sensor output signal.

Abstract: A radio frequency (RF) generator includes a RF power source configured to generate an output signal at an output frequency. The RF generator includes a frequency tuning module. The frequency tuning module generates a frequency control signal that controls the output frequency of the RF power source. The frequency control signal includes a frequency tuning signal component and a perturbation signal component. The perturbation signal varies an electrical parameter of the output signal. The frequency tuning signal is adjusted in accordance with a change in output signal in response to the perturbation signal.
