Patent number: 10857249Abstract: A room decontamination systems, controllers and methods for decontaminating a room. The room decontamination system may be a UV room decontamination system that uses UV radiation to perform a decontamination operation in the room. A controller may determine whether safe conditions for decontamination exist and initiate a decontamination operation on the basis of whether they exist. Determination of safe conditions for decontamination may be based on light actuation detection and/or sensor data, which may include presence detector data and door sensor data. Determination of safe conditions for decontamination may include a determination of whether sensors are functioning properly. The controller may also determine whether decontamination operations are required on the basis of the historical condition data, for example on the basis of whether the room has been occupied since the last decontamination operation.Type: GrantFiled: March 27, 2018Date of Patent: December 8, 2020Assignee: SANUVOX TECHNOLOGIES INC.Inventors: Normand Brais, Benoit Despatis Paquette, Jocelyn Dame

Patent number: 8747753Abstract: A controller for an ultraviolet (UV) purification system having UV lamps includes a sensor in communication with a given UV lamp as well as a processor in communication the sensor. The sensor provides the UV light intensity rate of the UV lamp (sensed rate) and transmits this information to the processor which compares the sensed rate with a memory stored desired UV light intensity rate (desired rate). An indicator in communication with the processor indicates when the UV lamp is producing a UV light intensity below the desired rate. Current is provided to the UV lamp by a ballast. The processor includes a memory stored predetermined UV light intensity rate (predetermined rate) that is greater than the desired rate. When the sensed rate is lesser than the predetermined rate, the current provided by the ballast is increased such that the UV lamp produces a UV light intensity at least equal to the predetermined rate.Type: GrantFiled: August 18, 2009Date of Patent: June 10, 2014Assignee: Sanuvox Technologies Inc.Inventors: Stuart Engel, Normand Brais

Patent number: 6805733Abstract: An outwardly projecting air purifier including a support, a generally cylindrical array of UV lamp assemblies mounted to the support, wherein each UV lamp assembly includes a reflector having a generally parabolic inner surface and a UV lamp so mounted to the reflector that the inner surface of the reflector reflects a portion of the ultraviolet radiation emitted by the lamp in an outward, radial, direction is described herein. The air purifier also includes a convex shaped deflector element so mounted to the support that the airflow is deflected by the deflector element and brought near the lamps.Type: GrantFiled: December 2, 2002Date of Patent: October 19, 2004Assignee: Sanuvox TechnologiesInventors: Stuart Engel, Normand Brais, Marc Lupien
