Abstract: An air extraction and treatment unit is located above a source of contaminated air. The apparatus has a series of ultraviolet tubes for treating the decontaminated air. The unit is arranged such that in use substantially no direct or reflected ultraviolet light is visible from outside the unit. Furthermore even when a removable filter is removed, there is no direct line of sight to the ultra-violet source. The unit further has a first switch being disposed between a first filter and the unit. The first switch modulates the ultraviolet tubes between at least a first condition and a second condition.

Abstract: A method and apparatus for regulating an amount of ozone incident to an air stream of an air purifier. The air purifier has a number of ultra violet light lamps, a catalyst, a first sensor, a second sensor, a ventilating duct, an array of baffles and a fan. The first sensor and second sensor detect a first and a second level of contamination of the air stream and, in response thereto, the array of baffles increase or decrease the travel path of the air stream for exposure by the UV lamps. The UV lamps and catalyst also move with respect to each other for varying the amount of exposure of the UV lamps to the contaminated air stream to regulate the ozone incident on the air stream. The improved apparatus improves the efficiency by regulating the amount of ozone incident to an air stream for varying cooking loads.

Abstract: A technique for detecting the toner solids concentration of a liquid toner uses electrostatic sensing and avoids reliance on optical transmission paths, which tend to clog and lead to undertoning or overtoning. The toner solids concentration is instead detected by measuring the residual electric potential of a developed area on an image bearing member. The residual electric potential has been discovered to correlate well with the toner solids concentration.
