Abstract: An air treatment system (1) arranged for treating polluted air (Apol) at least by means of an air particle filter, and wherein said air treatment system comprises an air treatment unit placed upstream of the air particle filter and being arranged for directing a sub-flow (Asub) of the polluted air (Apol) through said air treatment unit (2) and for subjecting the sub-flow (Asub) to a photooxidation process. The photooxidation process in the air treatment unit (2) is so efficient that the overall concentration of gas-pollution of the combined air flow Acorn is significantly reduced whereby large volumes of polluted air can be treated in a fast, inexpensive and effective manner.

Abstract: The present invention relates to an air treatment system (1) comprising a sterilization unit (2) arranged for producing ozone, a photooxidation unit (3) arranged for subjecting an air flow to a photooxidation process, and a control unit (4) arranged for in a first operational mode directing an air flow through the sterilization unit (2), and in a second operational mode directing an air flow through the photooxidation unit (3). By providing an air treatment system (1) which can operate in two different modes i.e. in a photooxidation or a sterilization mode, it is possible to specifically remove the undesirable pollutants in the air, e.g.

Abstract: In one embodiment, a distance that a target moves is calculated utilizing an optical sensor. A first temperature of a first portion of the optical sensor is measured at the time of the distance calculation. A second temperature of a second portion of the optical sensor is measured at the time of the distance calculation. The distance is adjusted by a compensation factor that is a function of the first and second temperatures.
