Patent EP-0421186-A2 (EP)
Inventor: GILGE MICHAEL DIPL-ING
IPC: H04N19/187
Filed: 1990-09-17
Abstract: To prepare digital image data for transmission via channels having a limited transmission capacity, a transformation coding is usually used for obtaining decorrelated coefficients. These coefficients are then quantised and transmitted. At the receiving end, the image is reconstructed from the quantised coefficients. The image content has previously been processed block by block which resulted in block-like interference patterns in coded images. In the invention, no block-by-block processing is used but image segments of any shape, which can be advantageously adapted to the local image content, are subjected to a transformation. For this purpose, a set of linearly independent two-dimensional basic functions is determined, the local extent of which is selected in such a manner as corresponds to a rectangle circumscribing the respective segment. New orthogonal basic functions are obtained by an orthogonalisation applied to the basic functions. For determining the coefficients describing the respective segment, the set of new orthogonal basic functions is applied in accordance with the transformation rule for rectangular areas.

Abstract: A conversion circuit generates a temperature- independent, dynamically compressed DC control voltage from an external regulation potentiometer. The conversion circuit uses a current mirror (T4,T5,T6) to convert linear variations in voltage (Vp) across the regulation potentiometer (Rt) into a logarithmic differential voltage between two output terminals (3, 4). One differential output (3) is fed to a unitary gain stage (B) which is blassed by a current generator (Ip) having a temperature coefficent corresponding to the reciprocal of the temperature coefficient of the integrated resistances. The output (5) of the unitary gain stage and the second current mirror output (4) are fed to a differential amplifier (C), which is also biassed by a current generator (Id) having a temperature coefficient corresponding to the reciprocal of the coefficient of the integrated resistances. On the output of the differential amplifier (6) is the required temperature-independent, dynamically compressed DC control voltage. The circuit is particularly useful for generating a control current for an AGC system.

Abstract: An electronic spreadsheet consists of an array of cells into which a user can enter formulas and values. The contents of the spreadsheet cells are translated into a query in a high-level logic language such as PLL. The query is then re-written according to the rules of the logic language, to produce an answer. The answer is then translated back into formulas and values which can be displayed on the spreadsheet. The system provides a number of facilities not available on conventional electronic spreadsheets: it provides the ability to give generalised answers containing formulas rather than simply numbers, and provides the ability to solve goal-seeking problems, working backwards from a desired result.

Abstract: A batteryless, portable, frequency divider includes a first resonant LC circuit (70) that is resonant at a first frequency for receiving electromagnetic radiation at the first frequency; and a second resonant LC circuit (74) that is resonant at a second frequency that is one-half the first frequency for transmitting electromagnetic radiation at the second frequency. The first circuit is coupled only magnetically to the second circuit to transfer energy to the second circuit in response to receipt by the first circuit of electromagnetic radiation at the first frequency. At least one of the resonant circuits includes a variable reactance element, such as a variable capacitance diode (D1 , D1 ) or a varactor. In a variable reactance element (D1 ) of the first circuit (70), the reactance varies with variations in energy received by the first circuit for causing the second circuit to vary in reactance due to mutual reactive coupling to cause the second circuit to transmit electromagnetic radiation at the second frequency in response to the energy transferred from the first circuit at the first frequency. In a variable reactance element (D2 ) of the second circuit (74), the reactance varies with variations in energy transferred from the first circuit for causing the second circuit to transmit electromagnetic radiation at the second frequency in response to the energy transferred from the first circuit at the first frequency. Both resonant circuits include inductance coils (L1 , L2 ) that are disposed on a ferrite rod (72), for enhancing the magnetic coupling. The frequency divider is included in a tag utilized in a presence detection system.

Abstract: High quality bisphenol A is produced from a neutral crystalline adduct of bisphenol A and phenol by fusing the adduct in an atmosphere having a maximum oxygen content of 0.005 % by volume, followed by evaporation of liberated phenol. The crystalline adduct may be mixed with an aliphatic carboxylic acid before the fusion to reduce the coloring of the product. When an acidic crystalline adduct is used, the use of a strong alkali salt of an aliphatic carboxylic acid is suitably used. Interior surfaces of the apparatuses for carrying out the fusion and evaporation are desirably washed with an organic solvent to remove oxygen therefrom. The evaporation of phenol is suitably performed by two stage steam stripping wherein a used stripping gas obtained in the second stage is employed as a stripping gas in the first stage while steam is used as the stripping gas in the second stage.
