Patents by Inventor Frédéric PITHOUD

Frédéric PITHOUD has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11691611
    Abstract: The invention provides a method of electrically powering an electromechanical braking actuator (1) fitted to an aircraft wheel brake, in which the power supply current (I) delivered to the electromechanical braking actuator is saturated to a saturation value (Isat) in order to limit the current consumed by the electromechanical braking actuator and thereby limit the forces developed by the actuator. The method includes the step of determining the saturation value (Isat) as a function of an internal temperature (T) of the electromechanical braking actuator while it is in operation.
    Type: Grant

  • Patent number: 9589223
    Abstract: A modular radio-identification system including a first passive radio-identification module having a housing with a memory for storing an identification datum disposed inside the housing and being linked to an antenna. The system also includes a second active radio-identification module having a housing with a controller disposed therein, the controller being linked to a supply battery, to a transmiter/receiver and to at least one sensor. The housings of the two modules are equipped with components of reversible and complementary fixing which are adapted for co-operating together so as to allow the reversible fixing of the second module on the first module. The modules include electrical connection components adapted for establishing an electrical connection between the memory and the controller once the second module is fixed on the first module. The system may be supplemented with a hood for covering the first module.
