Spatial Digital Systems Assigned Patent

Spatial Digital Systems, Inc., Agoura Hills, CA, has been assigned a patent (10,904,334) developed by Chang, Donald C. D., Thousand Oaks, CA, and Lee, Juo-Yu, Westlake Village, CA, for a “cloud data storage via cascaded K-muxing.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”For data writing, a first input device performs a first wavefront multiplexing transform on a first input stream and a first probing stream to generate L first intermediate streams. An en-route processing device generates J output streams from the stored L first intermediate streams and at least a second probing stream. For data reading, an en-route processing device generates L first intermediate streams and at least a first recovered probing stream from J input streams including a first stored probing stream. The L first intermediate streams are stored in a first storage site. A first output device performs a first wavefront demultiplexing transform on the L first intermediate streams to generate a first output stream and a second recovered probing stream. The J input streams are stored in a distributed storage structure having at least a second storage site that stores P of the J input streams.”

The patent application was filed on January 17, 2018 (15/873,892).
