Patent DE-4041821-A1 (DE)
Title: Digital colour TV signal memory storage arrangement - uses address generator to provide addresses for storage of luminance values in one memory and register and multiplexer to provide addresses for chrominance values to be stored in second memory
Inventor: FRIEDRICH BERND DIPL ING
IPC: H04N9/804
Filed: 1990-12-24
Abstract: A luminance value (Y) is determined for every pixel in the raster, while chrominance values (V, U) are determined only for every Nth pixel. A single address generator is used for storing the luminance and chrominance values for at least two values of N. The address generator (3) provides consecutive addresses for storage of the luminance value (Y) in a memory (4). The two chrominance values (V, U) are stored in a second memory (5) under the Nth address and the address following the Nth. Invalid data are written into the N-2 intermediate addresses. A register (11) and a multiplexer (13) are used to switch from one value of N to the next. ADVANTAGE - Can operate in 4:2:2 or 3:1:1 systems using common address generator.

Patent DE-4107300-A1 (DE)
Inventor: BAIER PAUL WALTER PROF DR ING
IPC: H04B1/713
Filed: 1991-03-07
Abstract: In a method for the correlative digital signal processing at the receiver end in a system for transmitting digital information having fixed-duration signal shapes, multiplications of received signal X and reference signals Yi and accumulations of the products are carried out in the course of n clock steps in a systolic arithmetic circuit (4). During the time when the input (1) of the arithmetic circuit (4) receives digitised samples X of the received signal, the input (2) is supplied with suitable reference values from a digital memory (9) which is connected to the address counter (10), and the accumulation values Ai already accrued are input at input (3) for adding up further products X.Yi. With the aid of a synchronising device (14), the digital circuit (8) controls the appropriate provision of the reference values Yi from the memory (9) and ensures that the registers of the arithmetic circuit (4) are emptied at the beginning of each signal shape to be received, and that the n accumulation values are successively read out of the register Rn of the arithmetic circuit (4), with open feedback loop from the output (6) to the input (3), via the connection (7) at the end of each signal shape duration and are processed further so that the received digital information items become available at the output (13) of the digital circuit (8). Using a device according to the method described, it is possible to build up matched filters operating purely digitally for signal shapes of a large variety in a simple and perfectly reproducible manner. Because of the low costs of such a structure, which can be achieved by large-scale integration, for example power supply grids can be opened up as a reliable medium for transmitting digital information by means of a band spreading technique, for example by means of frequency shift keying, for a large variety of applications. Complete modems consisting of transmitter and receiver can be implemented which can be widely adapted to various requirements, for example with respect to data rate and resistance to interference, due to their purely digital mode of operation.

Title: Composting bag of a starch-based polymer or starch-modified polymer
Inventor: EBNER RICHARD
IPC: C05F17/02
Filed: 1993-08-05
Abstract: The use of starch-based polymers allows the production of film bags which disintegrate within a period which can be predetermined. This effect can be exploited in particular in the field of substances of value which can be composted so as to make rapidly accessible the substances of value to the composting organisms (bacteria, fungi, worms) and to prevent slowly biodegradable polymers from contaminating the compost. This also solves hygiene problems when substances of value which can be composted are collected. Reinforced film bags which are provided with handles can first be used as shopping bags and here again as an advertising vehicle. Large composting bags are a useful alternative for collecting organic substances of value in the fields of catering and industry.
