The contacts with the regions to be connected are provided by conductive fingers substantially crossing the entire region with which a contact is desired to be established.
Abstract: A method for protecting the execution of a main program against possible traps, including, on occurrence of an instruction from the main program, starting a time counter of a given count according to next instructions of the main program, and executing, once the counter has reached its count, at least one instruction of a secondary program from which the result of the main program depends.
Abstract: A bit detection event within a read period is characterized by sub-dividing each read period into elementary time intervals. Certain ones of the elementary intervals are selected to for a window and a counting operation for a number of bits detected during the intervals within the window is performed. The elementary time intervals are defined by a difference between a frequency corresponding to the read period and a bit detection timing frequency. The counting result for the intervals in the window over several consecutive read periods is statistically processed. A reduction of an integrated electronic circuit test duration results from limiting the counting operations performed to the selected elementary time intervals.

Abstract: A method of transmitting data packets within a local network including a master unit and at least two slave units is adapted to a configuration according to which the master unit comprises two processors. The first processor executes an application and the second processor controls a transmission of data between the master unit and any one of the slave units. According to the method, data packets sent by a first slave unit to a second slave unit pass through the second processor and are forwarded directly in accordance with a readdressing directive obtained from addressing elements which are interassociated and communicated by the first processor to the second processor.
Abstract: An image adapter transforms an input image into an output image by successively processing tiles and by changing numbers of columns and of rows of image points. The image adapter includes queue memories connected in series so as to receive values associated with the points of a tile of the input image. A module for calculating a weighted average possesses inputs connected respectively to an output of one of the memories. The module produces values sampled in a direction parallel to the columns and corresponding to the values associated with points of the input image. A sampling rate converter, connected to the output of the module, produces values associated with the points of the output image according to a sampling rate determined for a direction parallel to the rows.

Abstract: A porous dielectric element is produced by forming a first dielectric and a second dielectric. The second dielectric is dispersed in the first dielectric. The second dielectric is then removed from the second dielectric by using a chemical dissolution. The removal of the second dielectric from the first dielectric leaves pores in the first dielectric. The pores, which are filled with air, improve the overall dielectric constant of the resulting dielectric element.
