Abstract: The invention relates to an intelligent portable personal security object including graphical personalization data visible from a face of the object, wherein the graphical personalization data are presented by electronic display. The invention also relates to a use of the portable object in the carrying out of secure electronic transaction; and/or in the authentication and visual monitoring of at least one person; and/or in logical access control for at least one user; and/or in the displaying of data other than graphical personalization data.

Abstract: The invention relates to a method for accessing an application. A token includes at least one application that is executable by a device. The token is coupled to the device. The method comprises the following steps. The token sends to the device data for identifying the token and data for authenticating the token. The device analyses whether the token identification data is included within a list of at least one authorized token. Only if the token identification data is included within a list of at least one authorized token, then the device analyses whether the token is authenticated. And only if the device authenticates the token, then the device authorizes to execute the application. The invention also relates to a corresponding device.

Abstract: As a component belonging to a class of components having hysteresis cycles of similar characteristics, the component of the invention subjects group of probes, in the absence of field-disturbing members situated in relationship with the probes, to a determined induction field so that a "bias" induction difference (B.sub.O) appears between the two groups, which difference is not less than the value of the high switchover threshold (B.sub.H), or not greater than the value of the low switchover threshold (B.sub.B), or else lies between the switchover thresholds (B.sub.H and B.sub.B), thereby obtaining a signal in a determined logic state at the output from the hysteresis level comparator in spite of induction difference dispersions lying between the minimum value of the low threshold (B.sub.Bmin) and the maximum value of the high threshold (B.sub.Hmax). The invention is applicable to differential detection Hall effect sensors.
