  • Method and device for protecting the integrity of data transmitted over a network
    Patent number: 9009839
    Abstract: A method of transmitting data over a network, from a sending application to a receiving application, including: coding the data, by the sending application, by implementing a predefined rule; detecting alteration of at least one item of data transmitted, by the receiving application, by implementing the predefined rule; and in case an alteration of a data item is detected, restoring the altered data item. In the course of the coding, in the course of the alteration detection, and in the course of the restoration, a cyclic redundancy check or an encryption can be implemented.
    Type: Grant

  • Control device and method for traction or braking
    Patent number: 5549365
    Abstract: A control device and corresponding method for controlling a traction function or a braking function of a vehicle, including a moving control lever which can be set in a first position 0 in which neither the traction function nor the braking function are activated, and an unstable position 0i in which the vehicle coasts by reducing electrical traction force and electrical braking force to zero. The control lever can be moved from the first position 0 over a first zone 0+ in which the electrical traction function is activated, either by increasing the electrical traction force, or by decreasing the electrical braking force. The control lever further can be moved from the first position 0 over a second zone 0- in which the electrical braking function is activated, either by decreasing the electrical traction force, or by increasing the electrical braking force.
