Abstract: A UV reactor for disinfecting water. The UV reactor may include a cooling chamber in which heat from a UV source may be transferred to the water flowing through the UV reactor. The UV reactor may include driver circuitry operable to determine status information, such as health, of the UV source. The UV reactor may include a gas discharge path operable to substantially prevent accumulation of gas within a water treatment chamber.

Abstract: An acoustic module with a transducer and a solid waveguide. The transducer and waveguide may be curved to focus the acoustic energy along a focal line. The transducer, the top surface of the waveguide and the bottom surface of the waveguide may extend along coaxial curves. The waveguide may include a recess closely receiving the transducer. The waveguide may include an integral skirt that provides a thermal mass. The acoustic module may include a space to accommodate thermal management options. For example, the acoustic module may include a heatsink, an active ventilation system and/or a phase change material. The ultrasound device may include a controller configured to perform a uniformity scan sweep during supply of operating power to the transducer. The uniformity scan sweep can extend through a frequency range that includes the operating point of the acoustic module and does not exceed an acceptable efficiency loss.

Abstract: A water treatment system is provided with an untreated water reservoir having a cavity through which a filter assembly may traverse such that untreated water in the cavity passes through the filter assembly into a treated water reservoir. Removal of the filter assembly may be facilitated by a seal disengagement element operable to unseat a seal formed during efforts to direct untreated water through the filter assembly.
