Title: Apparatus for controlling a hydraulic power system
Inventor: IZUMI EIKI
IPC: B60W10/06
Filed: 1981-10-08
Granted: 1987-02-13
Abstract: The hydraulic power system includes internal combustion engines to which fuel is supplied by fuel injection pumps and at least one variable volume type hydraulic pump. The rpm deviation is obtained from the difference between a target rpm number set by the amount the accelerator of the engine is opened and the output rpm of the internal combustion engine. A fuel injection amount target value having a predetermined relationship with the deviation is obtained based at least on one deviation. The amount of fuel injected by the fuel injection pump is controlled based on the fuel injection amount target value.

Title: Television transmission system using transform coding
Inventor: BORGERS STEPHANUS MARIA CHR
IPC: H04N7/30
Filed: 1988-04-09
Granted: 1997-03-28
Abstract: In a television transmission system for digital picture signals each picture is split up into sub-pictures of NxN pixels for the purpose of reducing the bit rate. Each sub-picture is subjected to a two-dimensional discrete cosine transform (DCT) for determining basic picture weighting factors (coefficients) which are converted by means of adaptive coding into code words of variable length. This two-dimensional DCT is realised by multiplying the pixels of each row of the sub-picture by the NxN DCT matrix (one-dimensional transform). Consequently, an NxN array of product elements is obtained. The transposed version thereof is once more multiplied by the NxN DCT matrix. Such a one-dimensional transform comprises three main steps. In a first main step the pixels of a row are converted in a first iteration step into N/2 sum elements u1,i and N/2 difference elements v1,i. In a subsequent iteration step the N/2 sum elements u1,i are converted into N/4 further sum elements u2,i and N/4 further difference elements v2,i. This process is repeated until only two sum elements are left. The difference elements obtained in each step are used to determine a plurality of auxiliary sum elements in still further iteration steps. The remaining two sum elements, the difference elements and the auxiliary sum elements are each multiplied in the second main step by an associated linear combination of elements of the DCT matrix. Of the sub-products thus obtained selected one's of those products are added together or are subtracted from each other in the third main step so that the desired product elements are obtained.
