Airbus Operations Assigned Patent

Airbus Operations, SAS, Toulouse, France, has been assigned a patent (9,436,393) developed by Robin, Jean-Luc, Saint-Jean, France, and Klein, Benjamin, Saint-Lys, France, for a “secure redundant storage device and secure read/write method on such a device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Redundant storage devices in particular suitable for so-called SSD electronic disks. A data storage system is proposed based on a plurality of redundant physical storage disks in which the read/write commands intended to be sent to the redundant disks are subjected to a transfer function before being sent to at least one of the disks so that the actual commands sent to at least two disks are different. The values returned by the disks that received the commands that had undergone the transfer function are subjected to the inverse transfer function. Thus, a design error in the control module of the disks will be detected, since the control modules of the disks will not be called identically.“

The patent application was filed on February 5, 2014 (14/173,087).
