    Abstract: A control mechanism for a high-voltage generator for supplying voltage and current to an electronic radiation source in high-temperature environments is provided, the control mechanism including at least one voltage feedback loop for monitoring the output of the generator; at least one environmental temperature monitor; a control bus; and at least one control processor. A method of controlling a high-voltage generator that powers an electronic radiation source in high-temperature environments is also provided, the method including at least: measuring the output voltage of the generator; measuring the temperature within the generator's environment, using a control mechanism to modify a driving frequency, and using a control mechanism to modify a driving pulse-train, such that changes in properties of the electronic components of the generator as a result of changes in environmental temperature are characterized and the generator's driving signals modified to maintain optimally efficient input parameters for a specific environmental temperature.

    Abstract: Oral care devices are provided that are capable of ejecting an air-liquid combination. In some implementations, the oral care devices include an applicator including a passageway within the applicator for directing the air-liquid combination therethrough; a plurality of brushing elements extending from a base at a head of the applicator to free distal ends, the head being sized to fit in a user's mouth; and a flexible nozzle in communication with the passageway and extending outwardly beyond the base at the head, the flexible nozzle configured to direct liquid droplets of the air-liquid combination beyond free distal ends of the brushing elements during brushing.
