  • Publication number: 20230202265
    Abstract: A nebulizer system for a motor vehicle may include a tank for a liquid, a nebulizer chamber, and a filter system capable of filtering the liquid contained in the tank for the liquid before it passes into the nebulizer chamber. The nebulizer chamber may have a nebulizer nozzle provided with an acoustic wave output device such that the liquid from the tank forms a mist of droplets of the liquid. The mist is intended to pass into a passenger compartment of the motor vehicle. Additionally, the nebulizer system may have an input module for air. The inlet module may have an air injection volute capable of channeling the air in the direction of the internal volume of the nebulizer chamber.

  • Patent number: 10990770
    Abstract: A portable object for near field communication with an external reader able to provide a magnetic field. The object has no internal power supply or energy storage. It includes a near field communication module having at least one antenna and a microcontroller for managing the near field communication; and a support member in the form of a bracelet for receiving the antenna. The object is designed such that the antenna extends substantially along the bracelet-shaped support member, so that, when the object is within the incident magnetic field, the antenna, which is wound over the length of the support member, is at least partly exposed to the field irrespective of the orientation of the object in space. Also provided is an an antenna for a portable object.

  • Patent number: 7451314
    Abstract: A cryptographic authentication method including a first step during which a first entity (A) to be authenticated sends an authenticator second entity (B) a message protected by a cryptographic algorithm and a secret key (Ks). During a second step, the second entity (B), after receiving said message, carries out operations selected from the group comprising completely verifying the authentication of the received protected message by means of said cryptographic algorithm and a verification key (Kv), delaying said complete verification, partly verifying said authentication, partly verifying said authentication and completing the verification subsequently, and omitting to verify said authentication. One of these operations is chosen as a function of the degree of certainty that the second entity (B) wishes to obtain as to the authentication of the first entity (A) and being concealed from the first entity (A).
