Abstract: Embodiments described herein methods can be used in particulate filter regeneration, such as particulate filters used for filtering the exhaust of an engine, e.g., a diesel engine. Systems herein can be configured to dispense combustion gas(es) into housing were a particulate filter is contained and to ignite the combustion gases. Methods for conducting a safety verification process of such systems are disclosed, as well as methods for regenerating the filters. Still other embodiments are described.

Abstract: Disclosed are systems, computer-readable mediums, and methods for receiving an input/output operation regarding data associated with a distributed storage system that includes a plurality of storage devices. A key identifier associated with the I/O operation is determined. The key identifier identifies a key that has been divided into a number of key pieces. Two or more storage devices of the plurality of storage devices that contain one or more of the key pieces are determined and at least a threshold number of key pieces are requested from the two or more storage devices. The minimum number of key pieces needed to reconstruct the key is the threshold number. The key is reconstructed from the requested key pieces. A cryptographic function is performed on data associated with the I/O operation using the reconstructed key and the I/O operation is completed based upon the performed cryptographic function.
