The present invention relates to a method of simulating the operation of an electronic circuit modelled by a numerical model comprising successive steps consisting in updating parameters of the model, periodically, at variable or constant simulated time step, when the battery is in a state of non-linear operation, and at each change of state of operation of one of the functional electronic components, when the battery is in a state of quasi-linear operation.

The endoprosthesis is designed to be implanted in an aneurysm () of a patient, the aneurysm () resulting from deformation of a vessel wall, in particular the wall of an artery (), the endoprosthesis including: a tubular envelope () that extends in a direction (Y-Y'), and a plurality of pressure probes () fixed on the envelope (), each probe () including: a sensor () for measuring pressure, and elements () for transmitting the pressure measurement to a monitoring apparatus located outside the patient. The elements () for transmitting the pressure measurement from each probe () are designed to generate an electromagnetic pressure measurement transmission signal including at least one distinctive characteristic of the probe () of which these elements () form part.

A process and apparatus are provided for estimating the movement of a moving object relative to a reference object. A symbol is formed on the moving object, the symbol having a rectilinear contour with at least two parallel straight lines. The symbol is observed from the reference object and the movement is determined by means of successive projections along two axes having a relative rotary movement with respect to the recorded image of the symbol. The rotary motion is preferably at such a rate that it does not interfere with obtaining images of the straight lines.

The retina is constituted by an array of cells formed on a substrate and each comprising a photosensitive element, means for converting a signal delivered by the photosensitive element into a binary information, storage means connected to the converting means and an elementary processor formed on the substrate and connected to the storage means. The storage means are arranged as a bidimensional array of shift registers to allow transfer of binary information from one cell to the neighboring ones, and the shift registers and elementary processors are connected in parallel to control inputs so as to control the acquisition of an image by simultaneously storing of the binary informations, the realization of simultaneous and parallel processings on the stored binary informations, and the write-in of the results in the storage means. Thus, successive processing steps of the image can be performed on the retina itself, the image being re-written on itself after each step.
