Abstract: A micrometric speaker includes a frame, an electromechanical transducer, and a mechanical-acoustic transducer comprising a rigid plate movably mounted in the frame. The electromechanical transducer comprises two piezoelectric actuators and two elastic strips. The frame comprises a central crossmember from which the two strips extend until engaging two lateral coupling edges of the mechanical-acoustic transducer, and the mechanical-acoustic transducer comprises two linearising springs each extending from one of the lateral edges to the rigid plate, to enable, during a deformation of the strips, a movement of the two lateral edges to the central crossmember and reduce the longitudinal constraints applied to the strips during their deformation due to their “recessed-guided” bending configuration.

Abstract: The present invention relates to a method for updating a firmware on a device, from a current version to a new version, said firmware being split into: —a core part, —an extended part comprising a plurality of entry points callable by the core part, said method comprising: —inhibiting the entry points between the core part of the current version, called current core part, and the extended part of the current version, called current extended part; —erasing the current extended part; —downloading the core part of the new version, called new core part; —erasing the current core part; —downloading—the extended part of the new version, called new extended part; —activating the entry points between the new core part and the new extended part.

Abstract: Disclosed is an acoustic transducer for converting a sound signal into an electric signal, including a mobile element movable under the effect of the sound signal, a fixed element opposite the mobile element, a recess, and a dissipative element between the mobile and fixed elements. The coupled system has a natural frequency corresponding to a resonance frequency of the transducer set at maximum sensitivity. The mobile element, the fixed element, the dissipative element and the recess are configured so the quality factor of the acoustic transducer>2. The recess has a straight prismatic, cylindrical, or frustoconical shape, the mobile element forming a first base of the prism, cylinder, or frustum, the fixed element being inside the prism, cylinder or frustum, over the second base of the prism, cylinder or frustum. Such a transducer also incorporates an analogue filtering function for filtering the signal around the natural frequency of same.

Abstract: An electronic device having one or more services made available to a host equipment with which it is connected. The device automatically adjusts the access capability to the services made available depending on the software platform available within the host equipment. The electronic device may include a platform identifier operating on data exchanged with the host equipment to identify the platform. The electronic device may be an electronic storage device providing access capability for reading/writing to memory, wherein the access capability is adapted to the host equipment. A memory may be partitioned into areas of memory dedicated to first and second types of software platforms available within the host equipment, and an area independent of the type of software platform. A memory may also be operated to list services authorized for a given platform, wherein a reference to this memory may be contained in a reserved memory.

Abstract: A secure portable electronic device for providing secure services when used in conjunction with a host computer having a central processing unit use two hardware device protocols readily supported by computer operating systems. Other systems and methods are disclosed.

Abstract: Data settings in a computer operating system are managed. The operating system includes sets of specific instructions (30-33), such as plugins, for managing configurations of software components (35) intended to run on the computer entity. A modification of settings required by an external program (20,21) involves a modification of configuration of the software components (35), through related plugins (30-33). The operating system is architected so as to include a repository (40,41) storing data of settings, and a main program (10) having access to the repository in read and write modes. Upon request from an external program for modifying settings, the main program (10) is adapted for transmitting the request to the plugins, receiving from at least one plugin a response including an information of modification of settings required by the external program, and, upon verification of the information, validating the modification of settings and updating related data in said repository.

Abstract: The invention relates to an electronic device having one or more services made available to a host equipment with which it is connected. The invention allows the device to automatically adjust the access capability to the services made available depending on the software platform available within the host equipment. The invention relates more particularly to electronic storage devices, the access capability of which to reading/writing to the memory is adapted depending on the host equipment.
