Abstract: A wrench assembly to assist in opening and/or closing a containment vessel in a water treatment system. The wrench assembly includes a primary handle configured to rotationally interlock with the main body of the containment vessel and a secondary handle coupled to the primary handle and configured to rotationally interlock with the closure of the containment vessel. The main body includes one or more engagement features configured to interfit with the primary handle. Similarly, the closure includes one or more engagement features configured to interfit with the secondary handle. The primary handle may include a guide portion defining an elongated slot that is configured to receive and guide movement of the secondary handle relative to the primary handle. The secondary handle may snap-fit into place within the slot. The primary handle may be configured to seat against a portion of the main body when properly positioned on the main body.

Abstract: A dynamic treatment system incorporates multiple pathogen reduction devices and sensors for enhanced pathogen reduction. The system can provide coordinated multi-level control to provide automated engineered control of pathogen reduction that is suitable for use in confined spaces, such as building and vehicle systems. Room level occupancy tracking provides biological load level estimates while pressure level sensing provides pathogen travel path estimation through the building. Combining this pathogen load information and airflow path information the system can drive room level and building level pathogen reduction device adjustments to enhance pathogen reduction based on expected pathogen travel. Zone level pathogen interception, height adjustable portable treatment devices, along with various application specific pathogen reduction devices can be integrated into the dynamic treatment system.

Abstract: A disinfection platform for at least partially disinfecting a proximal surface is provided. A disinfection apparatus includes a housing defining an aperture, a UV light source enclosed in the housing configured to project a UV illumination pattern toward a target disinfection area where the disinfection apparatus is disposed above one end and oriented at a downward angle. The illumination pattern output from the disinfection apparatus at least partially defined by louvers and an occlusion nose with reflective fins positioned at the aperture such that the illumination pattern at the target disinfection surface has improved intensity distribution. Multiple sensors cooperate with a control circuit operating the UV light source to provide intelligent and automated control with pattern detection, event based disinfection, and validation.

Abstract: A system for tracking the source of pathogens with a variable response and mitigation method utilizing a combination of UV, filtration, fans, communications and a control system. The control system monitors sensors that are indicative of pathogen propagation creating triggers and thresholds for a known measured response. The UV air treatment systems can generally include one or more UV air treatment fixtures as well as systems and methods for installing, operating, and maintaining the one or more UV air treatment fixtures. Some aspect emphasize features and configurations related to installation, operation, and maintenance of individual UV air treatment fixtures, while other aspects emphasize features and configurations related to coordination of multiple air treatment systems including data collection and control.

Abstract: A low profile disinfection and delivery system that utilizes a channel lighting system with a parabolic multifunctional anisotropic reflector for effectively distributing the power of UV LEDs. The channel lighting system delivers specific energy patterns to the target surface. The channel lighting system can be provided as a more integrated UV delivery system. The homogenous delivery and distribution of patterned energy enables better use and efficiency of the available UV LED power.

Abstract: A light fixture is provided to be disposed within a room and operable to provide visible light for the room and air disinfection via application of UV light to air flowing through an air treatment chamber. In one embodiment, one or more baffles may be disposed within the air chamber to substantially prevent UV light from leaking past the one or more baffles into the room. In one embodiment, a UV light regulator may be provided to selectively control an amount of UV light directed into the room.

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.
