Abstract: 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.

Abstract: A method for a binder-free manufacturing a nanostructured porous film, e.g. for use in solar cells, includes the steps of preparing a suspension of semi-conducting nanometer-sized particles in a volatile suspending agent (21), depositing the particle suspension on a conducting substrate, removing the suspending agent by evaporation (31), thereby leaving a particle layer on said substrate and compressing (P) the deposited particle layer for mechanical and electrical interconnection.

Abstract: An electrolytic cell assembly, e.g. for use in solar panels, is formed by placing coated metal wires (7,9) between the conducting layers (3,6) of two conducting glasses (1,4), respectively. A pressure force (F) is applied to press the metal wires between the conducting layers and to break the coating of the wires, thereby bringing the metal wires in electrical contact with the conducting layers. The coating protects the wires from harmful contact with an electrolyte inside the cell.

Abstract: The present invention discloses a color-modifying method, which comprises the provision of a metal oxide thin film (14) based on Ni and/or Cr. The method is characterized in that, when coloring the metal oxide film (14), exposing the metal oxide thin film to ozone, and when bleaching the metal oxide film, exposing the metal oxide film to UV radiation (18). A lamination process or a deposition of another thin film may follow the exposure. Preferably, exposing the metal oxide thin film (14) to ultraviolet radiation (18) in an oxygen-containing atmosphere (20) provides the ozone exposure and exposing the metal oxide thin film to ultraviolet radiation (18) in an oxygen-free atmosphere (20) provides the ultraviolet exposure.

Abstract: A device for indicating ice formation (and/or already existing ice) on a surface (6) of an object using a sensor (2) comprising a temperature difference measuring device, preferably a Peltier element (4), that has one of its contact surfaces (5) in thermal contact with the surface (6) which is exposed to ice formation. Ice formation is detected through measurement of the change in heat flow which occurs at the contact surface (5) due to the heat released in connection with ice formation, which measurement is carried out by connecting a voltage indicator to the connecting lines (11, 12) of the Peltier element. After having established that ice has formed, these wires can, if the sensor (2) is a Peltier element (4), be connected to a current source (13) for alternate heating and temperature sensoring of said contact surface (5), whereby the surface temperature will remain 0° C.

Abstract: A position sensor for non-contact position measurement includes a sensor magnet and a sensor body. The sensor body is formed from a magneto-resistive material and is given a two or three dimensional geometrical shape to achieve a desired sensitivity function. The desired sensitivity function results from a variation in one or more of the sensor body dimensions. By forming the sensor body of magneto-resistive material into different geometrical shapes like a simple wedge, a double wedge, a circular tapered form or an arbitrary shape, a desired sensitivity function is obtained.

Abstract: A body (40) is provided which is inserted between an ultrasound crystal (30) and an output port (27) in a probe filled with a fluid, to centrally defocus generated ultrasound and create an output ultrasound field having limited propagation, especially for higher intensities, after passing the output port. The casing is divided into three portions (21, 22, 23), whereby a front conical portion (21) including the output port (27) and the centrally defocusing body (40) is easily replaceable. The fluid in the casing is refilled via a tube connection (12) to a fluid storage connected as a communicating vessel to the ultrasound device. Moreover, the output port of the device is provided with a thin membrane (10), preferably of replaceable latex rubber, which is attached to prevent the fluid in the casing from emerging, but at the same time enabling the effective transfer of generated ultrasound. The membrane (10) may be attached by placing an O-ring gasket in a circularly formed slot (25) on the conical portion.
