Thomas PEYSSON 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: 9974133
    Abstract: An optoelectronic circuit intended to receive a variable voltage containing an alternation of rising and falling phases. The optoelectronic circuit includes assemblies of series-assembled light-emitting diodes, a node coupled to each assembly by a conduction circuit having its electric conductance varying according to a control signal and a control circuit coupled to each conduction circuit and capable of supplying each control signal based on the comparison of a first voltage at said node with at least a second voltage. The control circuit includes a difference amplifier and as many output stages as there are conduction circuits, the control circuit being capable of controlling the first voltage with the second voltage offset by a third voltage, different for each output stage.
