Abstract:
The subject matter of this specification can be embodied in, among other things, a circuit that includes a power module that includes an antenna. The power module is configured to generate power from a carrier signal received by the antenna. The circuit also includes a subcarrier generator powered by the power module when the carrier signal is received regardless of a communication protocol used in transmitting the carrier signal. The subcarrier generator generates an obscuring signal configured to obscure an information signal generated by another circuit energized by the carrier signal.
Abstract:
In some implementations, a mobile device includes a first interface configured to communicably couple to a removable integrated circuit card; a second interface configured to wirelessly communicate with a contactless reader that is external to the mobile device; a communication interface that couples the first interface and the second interface and that is configured to obtain information from an integrated circuit card that is coupled to the first interface in response to receipt by the second interface of an information request from the contactless reader; and a programmable timer that is configured to be started in response to the second interface receiving an information request from the contactless reader, and that is further configured to, upon reaching a programmed value, cause the second interface to transmit the obtained information to the contactless reader.

In another implementation, a power storage is configured to store power received by the second interface and provider stored power to the first interface, the second interface and the communication interface.
Abstract:
L'invention concerne une microplaquette de semi- conducteur, comprenant une face active sur laquelle est implantée une région de circuit intégré, comprenant au moins une plage de contact latérale inclinée s 'étendant en dessous du plan de la face active et reliée électriquement à la région de circuit intégré. L'invention concerne également un module électronique comprenant un substrat présentant une cavité dans lequel la microplaquette est agencée. Application notamment à la réalisation de micromodules sans contact de faible épaisseur pour cartes à puce, badges et étiquettes électroniques sans contact.
Abstract:
The invention relates to a semiconductor chip comprising an active face provided with an integrated circuit area which is implemented thereon and comprises at least one lateral inclined contact pad extending below the active face plane and electrically connected to the integrated circuit area. The invention also relates to an electronic module comprising a substrate provided with a cavity in which the chip is arranged. Said invention is used, in particular, for producing low-thickness contact-less micromodules for chip cards, badges and contact-less electronic labels.
