IPC: H03M5/04
Filed: 1995-02-01
Abstract: A a series of m-bit information words is converted to a modulated signal. For each information word from the series, an n-bit code word is delivered. The delivered code words are converted to the modulated signal. The code words are distributed over at least one group of a first type and at least one group of a second type. When a code word belonging to a group of the first type is delivered, its group establishes a coding state of a first type. When a code word belonging to an group of the second type is delivered, a coding state of a second type is established which is determined by the information word which is to be converted to the delivered code word. When one of the code words is assigned to the received information word, this code word is selected from a set of code words which depends on the coding state established. The sets of code words belonging to the coding states of the second type are disjunct. In this coding method, the number of unique bit combinations that may be established by the code words in the series are enlarged. The modulated signal obtained may be reconverted to information words by first converting the modulated signal to a series of code words and then assigning an information word to each of the code words from the series in dependence on the code word to be converted and also in dependence on the logical values of the bit string bits which are situated at predetermined positions relative to the code word.

Title: Bipolar data telegram transmission system - loses no data during temporary overloading and has easily expansible storage register
Inventor: FICK HERBERT DIPL-ING
IPC: H04L5/22
Filed: 1975-09-18
Abstract: The bipolar data telegram transmission system makes optimum use of transmission capacity without losing data during temporary overloading of the system (which handles telegrams from several data sources) and without presenting problems when the system requires enlarging. The first part of a transmit or receive register is used to store outgoing or incoming polarity change bits until these bits have been transmitted. After transmission, the bits are stored in the second part of the register as time code bits which are passed serially to the transmission line to act as time addresses. At the receiver terminal group and line addresses are used to assign the incoming telegrams to the appropriate destinations.

Abstract: La présente invention concerne des biomatériaux, c'est-à-dire, des matériaux qui sont utilisés en contact avec des tissus vivants et des fluides biologiques pour des utilisations dans le domaine des prothèses, de la thérapeutique, du stockage et similaires. En particulier, la présente invention concerne une nouvelle approche permettant de créer des surfaces biocompatibles, ces surfaces présentant une interaction fonctionnelle avec le matériau biologique. Ces surfaces comprennent au moins deux composants, comme un substrat hydrophobe et une macromolécule de nature hydrophile, qui coopèrent pour former une nouvelle surface biocompatible. La nouvelle approche se fonde sur la mise en contact dudit substrat hydrophobe avec une couche monomoléculaire à motifs latéraux de macromolécules hydrophiles et flexibles qui présentent un volume exclus prononcé. En ce qui concerne la polarité et la morphologie, la surface est une surface hétérogène du point de vue moléculaire. Les caractéristiques structurelles de ladite monocouche macromoléculaire (comme, par exemple, l'épaisseur de la couche ou sa densité latérale) sont déterminées par (i) les caractéristiques structurelles de la couche de macromolécules (comme par exemple, son architecture moléculaire ou son poids moléculaire) et (ii) le procédé consistant à créer ladite couche monomoléculaire (par exemple, par absorption chimique ou physique, ou par liaison chimique desdites macromolécules). Les caractéristiques structurelles de la couche de macromolécule(s) sont à leur tour déterminées par synthèse.
