Abstract: The present invention relates to a memory circuit (MEM) able to receive a first data block comprising a number of components and coming from an external memory (EXT) for them to be written (W) in an internal memory. The memory circuit is also able to supply (R) to an output device (FIL) a second data block comprising a component of said data. The memory circuit comprises data banks able to receive data words, and address controllers associated to the data banks and able to organize a reading or writing access of the data in the internal memory of the memory circuit, while minimizing the number of data banks used. Thus it is possible to rapidly read or write in the memory circuit at relatively low cost.

Abstract: The composition of an image [IM] comprises the step of mapping [MAP] a set of image sample values [SV] from a departure space [DEP] to an arrival space [ARR] in accordance with a geometrical transformation [T]. A zone in the departure space [ITL] is computed by applying the inverse geometrical transformation [T−1] to a zone in the arrival space [TL] covering a group of image samples. A group of input values [IV] is established for the zone in the departure space [ITL]. The group of input values [IV] comprises Boolean values [BV]. A Boolean input value has a certain position (xd, yd) in the departure space and designates the other input values having the same position as being non-valid if the position is outside the set of image sample values [SV]. The group of image samples [TL] is composed from the group of input values [IV].

Abstract: A set of image samples [IS] is established from a set of image sample values [SV] and geometrical parameters [V1, V2, V3] in the following manner. In an initialization step [INIT], a mask [MSK] is generated from the geometrical parameters [V1, V2, V3]. In a mapping step [MAP], the set of image sample values [SV] is mapped on the set of image samples [IS]. The mask [MSK] intervenes in this mapping.

Abstract: A transmitter and method for transmitting transponder or TCAS signals uses linear amplification to save on circuit component weight, cost and size while enabling precise amplification and control of the transmitted signal.

Abstract: The present invention relates to a process for the disposal of waste or the conversion of hydrothermally labile chemical groups and compounds to species which are environmentally acceptable, or are amendable to further degradation by conventional disposal systems to produce environmentally acceptable products, which process comprises:(a) conveying an aqueous solution or slurry of ordnance waste material into a reaction zone capable of withstanding the temperatures and pressures of hydrothermal decomposition;(b) reacting the waste material in the reaction zone with an aqueous composition comprising one or more alkali or alkaline earth metal silicates, borates, phosphates, biphosphates, or trisubstituted-phosphates, at between 200.degree. C. and 500.degree. C. and at a pressure between 10 and 400 atmospheres for between about 0.
