Alexandre Vernhet 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: 10067185
    Abstract: A system for characterising a NOR flash memory cell provided with a floating gate transistor, includes a voltage generator having an output connected to the gate electrode that generates as output an erase signal; and a dynamic measurement apparatus including a first channel connected to the gate electrode and a second channel connected to the drain electrode. The dynamic measurement apparatus generates on the first and second channels write signals and measures a current flowing in the drain electrode during the writing of the memory cell. Only the gate electrode of the floating gate transistor is connected to the voltage generator and to the dynamic measurement apparatus by a CMOS switch, which switches between a first position, where the output of the voltage generator is electrically coupled to the gate electrode, and a second position, where the first channel of the measurement device is electrically coupled to the gate electrode.

  • Patent number: 8806659
    Abstract: Systems and methods are provided to enable secure remote activation and/or unlocking of content or other media assets protected using one or more copy protection mechanisms or techniques. Existing trusted processor architectures used by electronic devices (e.g., HD-DVD or Blu-Ray optical disc readers) can be used to allow remote activation and/or unlocking of protected content. An authorization server is configured to identify the specific copy of the protected content or other media assets at the device from the request, and determine the correct correlation between the request and information that enables the device to initiate playback of the protected content. Accordingly, the authorization server maintains secret or private on the authorization server the information that can be used by other parties to obtain a correlation between the request and any response received from the authorization server that enable the device to initiate playback of the protected content.
