  • Communications protocol for asynchronous memory card
    Patent number: 6266725
    Abstract: In a method of communications between a host system and a memory card with an asynchronous transmission protocol, a message from the card is sent out in response to a control instruction comprising a character or a sequence of several characters in a predetermined format. The protocol is modified so as to have the dispatch of each message or of each character of a message preceded by a detection, by the card, of a response request instruction sent out by the host system.

  • Electrostatic protection device for electronic cards
    Patent number: 4942495
    Abstract: In an electrostatic protection device for electronic cards, the electronic card has a module bearing, on one of its faces, a network of conducting tracks to which at least one integrated circuit is connected. Each contact is close to a contact at a reference potential. The contact bears, on its periphery, metal sharp-pointed proturberances placed so as to face other metal protuberances borne by the contacts so as to favor the formation of electric arcs between two facing protuberances.
