Title: Method for protecting a software using a so-called renaming principle against its unauthorised use
Inventor: CUENOD JEAN-CHRISTOPHE
IPC: G06F21/12
Filed: 2002-07-04
Abstract: The invention concerns a method for protecting, from a unit, a vulnerable software against unauthorised use, said vulnerable software operating on a data processing system. The inventive method consists in defining: a set of dependent functions whereof the dependent functions are executable in a unit; a set of triggering commands, said triggering commands capable of being executed in the data processing system and of triggering execution of the dependent functions in a unit; for each triggering command, an instruction; a method for renaming the instructions; and reinstating means for implementation in a unit during a use phase, and enabling to recover the dependent function to be executed, from the renamed instruction.

Filed: 1998-09-30
Abstract: The switching regulator has a transformer (Tr) with its primary winding (Wp) in series with a controlled switch (T) connected to an input DC voltage. A secondary winding (Ws) is connected to a rectifier and charging capacitor. A drive circuit is fed by a current sensor. with two regulating amplifiers (Kd,Ks) to influence the duty cycle. The maximum power of the regulator's primary part is lower than the product of the maximum output voltage and output current that can be set. The maximum reference values (URefU,URefl) that can be set corresponding to the voltage and current values with which the secondary part can be loaded at maximum. The height of the control signal is limited, and the limiter's (Dz) action point is selected so that a maximum switch-off current in the primary circuit corresponds to the maximum permissible primary circuit power loading.

Abstract: ABSTRACT OF THE DISCLOSURE           A digital data switch of the time-space-time (TST) type for switching pulse code modulated (PCM) data is disclosed.  The switch combines a parity bit with each PCM word being switched in a conventional way to supervise the internal operation of the switch. The invention consists of a method of using such a switch for checking that a correct or intended connection is made through the switch by inserting incorrect parity with PCM words to the in-put in question immediately after the connection is established and checking the outlets of the switch to determine the output/s having incorrect parity.  The check is made by the central control of the switch which compares the output/s having incorrect parity with the intended output/s.  A simple circuit arrangement for dis-tinguishing deliberately introduced wrong parity from through con-nection faults is also disclosed.

Granted: 1978-12-26
Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a method and apparatus for applying fluid to an intaglio roll for subsequent transfer to a soft, absorbent fibrous web passing in contact with the intaglio roll.  The fluid is flowed upwardly through a small unpressurized reservoir extend-ing across the width of the intaglio roll, which forms a confining member of the reservoir and overflows a second confining member of the reservoir spaced from the intaglio roll.  The fluid is flowed into the reservoir with uniform flow velocity profile across the width of the reservoir, created preferably by flowing the fluid against an impingement member prior to entering the reservoir.         The intaglio roll is rotated upwardly through the reservoir to establish a first layer of fluid adhering to the roll above the reservoir and the intaglio roll is rotated past a unique pre-wipe member positioned adjacent the intaglio roll above the reservoir.         The pre-wipe member uniformly distributes the fluid in the first layer across the width of the intaglio roll, assures filling the fluid carrying recesses with the fluid and establishes a reformed layer of fluid adhering to the roll above the pre-wipe member, the reformed layer having less thickness than the first layer.  The intaglio roll is then rotated past a doctor blade positioned against the intaglio roll beyond the pre-wipe member to remove essentially all of the fluid adhering to the intaglio roll except the fluid within the fluid carrying recesses.
