Abstract: A method and apparatus for masking errors in a DRAM write are disclosed to perform a partial write request with an SSD controller. In embodiments, write data from a host is provided to the controller that is not aligned to the DRAM data. The controller issues a read command from the LBA of a data storage device, and a corresponding write command to write the data received from the host, prior to receipt of the read data, to perform a partial write. The read data is error corrected, and in the event an error is found in the read data, bytes containing an error are masked. The read data, including masked read data, and write data are merged to form partial write data, and written to the DRAM. In certain embodiments, the partial write data may be provided to a logic analyzer to assess the masked read data for debug analysis.

Abstract: A system and method for encoding data using a plurality of encoding libraries. Portions of the data are encoded by different encoding libraries, depending on which library provides the greatest compaction for a given portion of the data. This methodology not only provides substantial improvements in data compaction over use of a single data compaction algorithm with the highest average compaction, but provides substantial additional security in that multiple decoding libraries must be used to decode the data. In some embodiments, each portion of data may further be encoded using different sourceblock sizes, providing further security enhancements as decoding requires multiple decoding libraries and knowledge of the sourceblock size used for each portion of the data. In some embodiments, encoding libraries may be randomly or pseudo-randomly rotated to provide additional security.

Abstract: A user equipment (UE) may receive an OFDM signal having control channel elements (CCEs). The CCEs may be arranged in levels where a first level aggregates less CCEs than a second level. A processor may search for a control channel from control channel candidates that is comprised of the CCEs. A limited number of CCEs may be searched on the first level.

Abstract: An autonomous mobile device has a main body and an extensible mast to raise and lower a payload, such as a camera, relative to the main body. The mast may comprise a set of telescoping sections, with each section comprising two or more pieces that are joined during assembly. A motor moves a flexible rack between a first spool and the mast to raise or lower the mast. For example, during extension a motor-driven pinion engages teeth on the flexible rack, pulling the rack from the first spool and pushing up the mast. A cable stored on a second spool may be extended and retracted with the flexible rack. The cable transfers one or more of data or power between the main body and the payload. A sensor may be used to detect features on the flexible rack to provide data about how far the flexible rack has been extended.

Abstract: Systems and methods are described for modifying input and output (I/O) to an object storage service by implementing one or more owner-specified functions to I/O requests. A function can implement a data manipulation, such as filtering out sensitive data before reading or writing the data. The functions can be applied prior to implementing a request method (e.g., GET or PUT) specified within the I/O request, such that the data to which the method is applied my not match the object specified within the request. For example, a user may request to obtain (e.g., GET) a data set. The data set may be passed to a function that filters sensitive data to the data set, and the GET request method may then be applied to the output of the function. In this manner, owners of objects on an object storage service are provided with greater control of objects stored or retrieved from the service.

Abstract: A heat-assisted magnetic recording (HAMR) head has a protective multilayer confined to a window of the disk-facing surface of the slider that surrounds the near-field transducer (NFT) end and write pole end. The protective multilayer is made up of a first film of silicon nitride directly on and in contact with the NFT end and the write pole end and a second film of a metal oxide on and in contact with the silicon nitride film. The silicon nitride film is preferably formed by RIBD but is thin enough so that it does not contain any significant amount of other compounds. The metal oxide is preferably silicon dioxide, or alternatively an oxide of hafnium, tantalum, yttrium or zirconium, and together with the silicon nitride film provides a protective multilayer of sufficient thickness to be optically transparent to radiation and resistant to thermal oxidation.

Abstract: Embodiments of the present disclosure generally relate to a target device handling overlap write commands. In one embodiment, a target device includes a non-volatile memory and a controller coupled to the non-volatile memory. The controller includes a random accumulated buffer, a sequential accumulated buffer, and an overlap accumulated buffer. The controller is configured to receive a new write command, classify the new write command, and write data associated with the new write command to one of the random accumulated buffer, the sequential accumulated buffer, or the overlap accumulated buffer. Once the overlap accumulated buffer becomes available, the controller first flushes to the non-volatile memory the data in the random accumulated buffer and the sequential accumulated buffer that was received prior in sequence to the data in the overlap accumulated buffer. The controller then flushes the available overlap accumulated buffer, ensuring that new write commands override prior write commands.
