Patent DE-4113505-A1 (DE)
Inventor: HERPEL CARSTEN
IPC: H04N19/98
Filed: 1991-04-25
Abstract: Transformation circuits for carrying out an 8*8 or 2*(4*8) DCT transformation exist. Switching between a 8*8 or 2*(4*8) DCT can be carried out by suitable choice of the logical level of a connecting line. Hybrid coders for picture signals are known which process blocks of progressively scanned input signals using DCT, blocks of 8*8 pixels being coded or decoded in each case. In the case of dynamic picture contents, the lines belonging to a field are combined to form a first 8*8 block, and the lines belonging to the corresponding second field are combined to form a second 8*8 block from these two superposed 8*8 pixel blocks and fed in this form to the hybrid coder. As a result of the reorganization of the input signals, switching between an 8*8 and a 2*(4*8) DCT transformation in the hybrid coder is unnecessary for interlace input signals, but an 8*8 DCT can be advantageously carried out also for a dynamic picture content.

Title: Transportation system for passengers and transporters - has transporters, which sort themselves automatically on carrier transporters, to avoid unnecessary stops
IPC: B61B13/00
Filed: 1991-11-25
Abstract: The system has carrier transporters, which move passengers and transportable transporters. The carriers combine and separate during travel. The transporters move in carriers and over the connectors between the carriers. A carrier approaching a stop, connects itself to a carrier, which does not halt at this stop, for compound travel. During compound travel, passengers and transporters sort themselves, so that the carrier, which is to stop next, carries no passengers or transporters, which do not require this stop. After this travel mode, the carriers separate, so that one moves on, and the other one stops. The process is then repeated. ADVANTAGE - Improved travel speed, without shortening stopping times and reducing number of stops.
