Pollutant decomposition device, including at least one outer transparent sheet and at least one inner transparent sheet being arranged such that a gap is formed between them and such that the gap is in communication with a surrounding gaseous composition on one side of the device such that the gaseous composition can pass through the gap. The device further including a photocatalyst arranged in the gap for depolluting the gaseous composition that pass through the gap. To obtain optimum decomposition efficiency the outer transparent sheet has a high degree of ultraviolet transmittance compared with the inner transparent sheet.

Pollutant decomposition device

Electrochromic film with the general formula: ApBqOxXy wherein: &#x2014;A is one or more of the elements from the group consisting of Ni, Ir, Cr, V, Mn, Fe, W, Mo, Ti, Co, Ce, Pr and Hf; &#x2014;B is one or more of the elements from the group consisting of Mg, Ca, Sr, Ba, Nb, Al, Zr, Ta and Si; &#x2014;O is oxygen; &#x2014;X is an element from the group consisting of: H, F and N; and the ratio q/p is greater than 0.2 and less than 3.5, x is greater than 0.5 (p+q) and less than 5 (p+q), and y is equal to or greater than 0 and less than 2x. The film may further comprise an amount of Li, Na or K. The invention further relates to an electrochromic device comprising at least one layer of said electrochromic film.

Electrochromic film and device comprising the same

The invention relates to a climate control system comprising at least one radiation reducer and a climate control unit for controlling the radiation reducer. Which system further comprises a usage detection system coupled to the climate control unit. It also relates to a method of climate control in a room, using a climate control system comprising at least one radiation reducer, which method comprises the steps of detecting if the room is in use or not, if in use, setting the radiation reducer in a mode of high transmittance, if not in use, setting the radiation reducer in a mode of low transmittance.

Climate control system and method for controlling such

An electrochromic device (,) for windows, displays, rear view mirrors, eye wear and other applications includes three layers (,), (,) and (,) of electrochromic materials and an electrolyte, with the transmittance of the layers (,) and (,) being variable by an applied electrical field, and protective layer (,) being transparent and not contributing to the coloration/bleaching of device. The protective layer (,) is made of the same electrochromic material as the electrochromic layer on the opposing side of the electrolyte.

Electrochromic device comprising tandem layers of cathodic/anodic materials
