    • The invention relates to a method for coding discrete time signals (x1) sampled at a first sampling rate. According to said method second time signals (x2) are generated using the first time signals, the band width of which corresponds to a second sampling rate which is lower than the first. The second time signals are coded in accordance with a first coding algorithm. The coded second time signals (x2c) are decoded again so as to obtain coded/decoded second time signals (x2cd), the band width of which corresponds to the second sampling rate. The first time signals are transformed by frequency range transformation into first spectral values (X1). From the coded/decoded second time signals second spectral values (X2cd) are generated, which are a representation of the coded/decoded second time signals in the frequency range. To obtain weighted spectral values the first spectral values are weighted with the second spectral values, whereby the first and second spectral values have the same frequency and time resolution. The weighted spectral values (Xb) are coded, taking into consideration a psychoacoustic model, in accordance with a second coding algorithm and entered into a bit stream.

    • The invention relates to a device for protection against the sun of Venetian blind type with a plurality of parallel lamellae with horizontal longitudinal axes, which pivot around their longitudinal axes by means of a regulating mechanism. The device is characterized in that these lamellae, or a coating applied to the upper surface of the lamellae, consist of translucent material, and have a cross section perpendicular to the longitudinal axis of the lamellae. This cross section consists of a) first flat sections which are arranged obliquely to the upper surface of the lamellae and receive the sun's rays approximately perpendicular, b) second flat sections which are flush mounted, at an acute angle of approximately 45 DEG to the first flat sections, and c) a third flat section which is approximately perpendicular to the second flat sections, in such a way that adjacent first and second flat section pairs are separated by a distance, thus enabling a shadow-free irradiation and reradiation over the first sections, when the sun's rays hit the first sections in approximately perpendicular fashion. This distance makes it possible to dispense with all connectors, or to fit visual connectors, of which one upper surface coincides with the upper surface of the lamellae, and another upper surface lies parallel to the third side or coincides with it.

    • In a process for sensing an image signal by means of an array (30) of photosensitive components (10) capable of varying the charge of a capacity (12), an optical signal (20) from each photosensitive component is at first sensed by the following partial steps: a charge state of the capacity is generated with a predetermined voltage (+U_DD), the charge of the capacity (12) is altered by means of a photocurrent generated by the optical signal (20) in the photosensitive component (10) or by means of a value derived therefrom, and the voltage through the capacity (12) is sensed after a predetermined period. The sensed voltage is evaluated to verify if it lies within a valid range. If that is the case, a valid signal which characterises the sensed optical signal is determined on the basis of the sensed voltage. If that is not the case, the above-mentioned steps are repeated, applying a period which differs from the predetermined period, for a predetermined number of times or until the sensed voltage is detected to be in a valid range. Afterwards, the optical signal sensed by each photosensitive component (10) is stored together with the period during which a valid signal was detected. Finally, the image signal is extracted from the stored optical signals for the individual photosensitive components and their respective periods.
