Abstract: The present invention discloses a display structure comprising at least one display module, wherein the display structure comprises at least one substrate layer comprising polymer, glass, ceramic or composite materials and integrated electrically conductive circuitry with electronics, where applicable, and light emitting devices; at least one electrically conductive layer, enabling intelligent control of the light emitting devices; wherein a display module comprises at least one coating or molded layer protecting the display structure from moist and other environmental effects; the display structure further comprises, when applicable, a number of structured, through-holes reaching through the whole display structure; the display structure is configured to be constructed from smaller, manufacturable sized display modules by interconnecting suitable amount of display modules into rows and columns; and the display structure is applicable to harsh environments comprising ice and outdoor conditions.

Abstract: The present invention is a flexible thin film based screen or illumination apparatus with a stacked layer structure or a one-layer structure. Transparent polymer is preferably used in different layers, and energy can be collected directly by a solar panel layer of the screen structure. Different resolutions are available through using a various number of layers with LEDs. Frames and connecting means can be used and a special connection principle enables selected layers of a single module, and/or selected layers of adjacent modules to be electrically coupled. The present invention can be used in any planar or non-planar shape, and as a single-sided or dual-sided LED screen or illumination device, e.g. as information screens, traffic information means, advertisement platform, in architectonic media surfaces, in sports venues, and for various entertainment purposes. Wireless and IoT connectivity means can be provided in the apparatus.

Abstract: The invention relates to a method and apparatus for recognizing a digital audio signal in a system, in which at least some of the electronic components are at times in sleep or unenergized mode, in which method the digital audio signal is amplified and recognized, the amplified signal is decoded in a decoding circuit, the decoded signal is led to a signal processor for further processing and digital/analog conversion, and an audio signal is created from the analog signal. According to the invention, the amplified, undecoded signal is led directly to the signal- or microprocessor to be used and recognized, and the circuit implementing the decoder is kept in sleep mode unless a digital audio signal has been recognized.

Abstract: A web-forming section of a paper or board machine has a first web-forming unit with a first fiber layer (W1) formed on a first wire (10); a second web-forming unit with a second fiber layer (W2) formed on a second wire (30); and a couch shoe (39) over a curved deck (40) of which the fiber layers (W1, W2) are guided for joining them together. The second fiber layer (W2) is brought to the couch shoe (39) at an angle (?) of less than 20°, advantageously less than 15° in relation to the approach direction of the first fiber layer (W1). The couch shoe (39) is provided with underpressure and the radius of curvature of its deck (40) is usually larger than the radius of curvature of a guide roll (38) preceding it. By the couch shoe, the fiber layers can be joined together wetter than usual.

Abstract: An identification method and apparatus in a sound-reproduction system, in which an electrical calibration signal is created, an audio signal is created in the loudspeaker from the calibration signal, the response of the audio signal is measured and analysed, and the system is adjusted on the basis of the measurement results. A light signal is created in the loudspeaker with the aid of a centralized control system, in order to indicate visually the loudspeaker that is the subject of the calibration.
