Abstract: A user-specific, electroencephalogram data-based secure encryption generator maps artificial neural network neuron elements to electroencephalogram data signals generated from scanning neural activity of a user while the user executes a mental activity. Weighting factors are trained to transform the electroencephalogram data signals into a first set of weighted signals that are different from weighted signals generated from scanning neural activity of the user while the user executes another, different activity, and from weighted signals generated from scanning neural activity of another user while executing a similar mental activity. The trained weighting factors are associated with the first set of electroencephalogram data signals and the current mental activity. Thus, a reproducible electroencephalogram encryption key is defined that is unique to the user as a function of one or both of the trained weighting factors and the first weighted set of electroencephalogram data signals.

Abstract: A data stream is stored in storage media. As part of the storage, the data stream is divided into a plurality of chunks. The plurality of chunks include a target chunk that is next to a first chunk in a file within the data stream. A determination is made that the target chunk matches an existing chunk stored in the storage media. In response to the determination, a first pointer to the existing stored chunk is created in file metadata for the file. Also in response to the determination, a second pointer to a first stored chunk that matches the first chunk is created in chunk metadata embedded with the existing stored chunk.

Abstract: A technique for operating a data storage system includes accessing respective absolute expiration times for valid pages in one or more candidate storage blocks. Garbage collection is performed on ones of the candidate storage blocks that include a first predetermined number of the valid pages that do not expire, as indicated by the absolute expiration times, prior to a first predetermined time period. Garbage collection is deferred on ones of the candidate storage blocks that include a second predetermined number of the valid pages that expire, as indicated by the absolute expiration times, prior to a second predetermined time period.

Abstract: Transferring data from a first data storage drive of a first data storage library to a first computer system that is connected to a second data storage drive of a second data storage library. A data transfer request for transferring data accessible by the first data storage drive to the first computer system is received. A network connection is initiated between the first and the second data storage drive. An access to the requested data is initiated by the first data storage drive. A transfer of the requested data from the first to the second data storage drive via the network connection is initiated. A transfer of the requested data from the second data storage drive to the first computer system is initiated.

Abstract: Transferring data from a first data storage cartridge of a first data storage library to a second data storage library. The first library includes a first data storage drive, the second library includes a second data storage drive. A mounting of the first data storage cartridge into the first data storage drive is initiated. A network connection between the first and second data storage drives, with both data storage drives operating in a data transfer mode, is initiated. A mounting of a second data storage cartridge into the second data storage drive is initiated. A copying of the data content of the first data storage cartridge onto the second data storage cartridge via the network connection is initiated. A deletion of the data of the first data storage cartridge is initiated.

Abstract: Some embodiments are directed to tape drive systems that oscillate the relative transverse position of the tape and magnetic head during seek operations (for example, by moving the head in the transverse direction). Some embodiments are directed to tape drive systems that select relative transverse position of the tape and magnetic head to counter uneven wear (for example, observed uneven wear, uneven wear predicted based on historical tape and drive usage data).

Abstract: Transferring data from a first data storage cartridge of a first data storage library to a second data storage library.

If the first and second libraries are not connected by a mechanical pass-through, mounting the first data storage cartridge into the first data storage drive. A network connection between the first and second data storage drives, with both data storage drives operating in a data transfer mode, is initiated. Mounting a second data storage cartridge into the second data storage drive. Copying the data of the first data storage cartridge onto the second data storage cartridge via the network connection, and deleting the data of the first data storage cartridge. Else, transporting the data cartridge from the first library to the second library via the mechanical pass-through.

Abstract: A storage element for a warehouse rack may be provided. The storage element is adapted for housing goods and can be positioned compact in at least two dimensions. The storage element comprises a computing device comprising a memory storing at least a unique identifier and data about the goods housed by the storage element, a plurality of antennas external to the computing device mounted at outer sides of the storage element. The antennas are adapted for a communication to antennas of neighboring storage elements. The antennas are electrically connectable to the computing device. The storage element also comprises a switch controller adapted for switchable connecting one of the plurality of antennas to the computing device at a time.

Abstract: A tape drive system with a transducer (for example, a magnetic head arrays/separation shield) located in a recess of a transducer housing (for example, supporting rails, a U-shaped carbon tape guide). During seek operations and/or data access operations (that is, read/write operations), the transducer and the transducer housing are moved, in the transverse direction relative to the direction of elongation of the tape, independently of each other. The motion of the transducer housing (for example, back and forth oscillatory movement in the transverse direction) is controlled to even out wear across the tape-facing surface of the transducer housing. Some embodiments accomplish this by using separate motors to transversely move the transducer and the transducer housing.
