Title: Domestic water purifier
Inventor: ARCARI VITTORIO
IPC: C02F/
Filed: 1986-09-26
Granted: 1988-11-30
Abstract: Character contours are broken down into a series of orthogonal vectors. Pixel drop out occurs where opposite going vectors coincide. The inside pixel (410 or 440) of each vector (400 or 430) is set to the vector length if the length is greater than the set values of the inside and the outside (420,450) pixels. This procedure is repeated for all the vectors for all the contours. At completion all those pixels set to one or more are set on to produce a drop out corrected bit map which is logically OR'd with the original drop out containing bit map.

Patent PT-96376-B (PT)
Inventor: DRESSLER HANS-JOACHIM
IPC: H03D1/00
Filed: 1990-12-27
Abstract: The invention relates to an interpolative analog/digital converter for band-pass signals in which the amplitudes of the scanning values are quantized in 2 consecutive stages. The first stage contains the actual analog/digital interface and the second stage is purely digital. The amplitudes of the scanning values are not quantized, as in other processes, using finely quantizing elements at the analog/digital interface, but by overscanning, shaping of the quantization noise spectrum and digital interpolation. As a result, very coarsely resolving elements (with only 2 quantization stages in the extreme case) can be used at the actual analog/digital interface.
