A method that builds a chain-of-custody for archived data is disclosed to ensure the integrity and reliability of the archived data. In one implementation, by using a certified Time Stamp Authority (TSA), an indelible record of each time the archived data is touched (e.g. created, stored, retrieved, accessed, tested, moved, or transformed) is generated to build verifiable links between events to ensure the custody of the data can be audited and verified that it has remained intact throughout its lifetime. The chain-of-custody, in combination with the storage architecture that ensures archive data has not changed through various software and hardware means (e.g., multiple hash signatures to ensure integrity, timestamp authorities to pinpoint each time the archived data was touched, location information to pinpoint physical location, and coordinated chain of custody on multiple replicas of the digital artifact) validates that the archived data has not changed since it was archived.

Chain-of-custody for archived data

A tape library is provided with a fixed coupling mechanism so that the tape library includes discrete locations via which power and communication are provided to an accessor. The use of such a coupling mechanism in a vertical tape library allows for the use of gravity to ensure that the accessor can couple with the fixed coupling mechanism even when no power is present in the accessor.

A removable media battery pack for supplying power to a media accessor of an automated data storage library. A media shell of the removable media battery pack has a structural configuration operable to be physically engaged by a media shell gripper of the media accessor. A rechargeable battery of the removable media battery pack is disposed within the media shell. A media shell interface of the removable media battery pack is integrated with the media shell and coupled to the rechargeable battery to provide power to the media accessor.

An apparatus and a method for the exchange of power-supplied batteries which are arranged in a media-conveying untethered robot which is located in an automated data-storage library.

A system and method for creating a high-level application programming interface allows simplified control and usage of digital data being transported over an IEEE 1394 serial bus under a variety of operational environments. The system and method of controlling communications on a communications bus includes determining a number of adapters attached to the communications bus, establishing a link between an application program and one or more of the adapters; allocating buffers for data transfer; mapping a memory buffer to a space in storage associated with the communications bus; and executing the applications program.

Method, product and system alters audio data for a synthesized voice so that when it is produced on a speaker system, it appears to emanate from a spatial position. First, the voice is synthesized into a speech waveform from a set of stored data representative of a text string using standard techniques. The speech waveform is converted into analog signals for a right and left channel. According to the invention, the analog signals to the right and left channels are altered according to position data stored with the text string so that the synthesized voice appears to originate at the apparent spatial position when the analog signals are sent to a speaker system.

Three dimensional speech synthesis

A technique for producing a sound of a plurality of a selected instrument from a digitized audio sample of the selected instrument. The digitized audio sample of the single selected instrument is stored in a memory. Next, copies of the digitized audio sample are micromanipulated in parallel in a plurality of digital processors corresponding in number to the plurality of the selected instrument. Each of the digital processors processes the digital audio sample in a slightly different time variant manner to produce the effect of a plurality of instruments. The processed digital audio samples are summed into a single digital sample. The summed digital audio sample is converted to an analog signal which is sent to a speaker to produce the sound of the plurality of the selected instrument.

A method and system for automatically generating an entire musical arrangement including melody and accompaniment on a computer. The invention combines predetermined, short musical phrases modified by selection of random parameters to produce a data stream that can be used to drive a MIDI synthesizer and generate music.

A method and apparatus are disclosed for the audio editing of MIDI (Musical Instrument Digital Interface) files. MIDI files make it possible to exchange information such as: musical notes, program changes, expression control and channel information between musical instruments, sequencers, computers, lighting controllers and mixers. MIDI files generally consist of serially listed channel and system messages which include at least program status messages and matching note on and note off messages. The method and apparatus of the present invention may be utilized to ensure the integrity of a source file, a copied or lifted section or a target file by automatically inserting matching note on or note off messages into a file or file section to correct inconsistencies created by such editing. Additionally, program status messages are automatically inserted into source files, copied or lifted sections, or target files to yield results which are consistent with the results which may be obtained by editing digital audio data. Timing information is selectively added or maintained such that MIDI files may be selectively edited without requiring a user to learn a complex MIDI sequencer.

Method and apparatus for audio editing of MIDI files

A system and method for translating MIDI files is used with a sequencer and synthesizer. When a MIDI file is imported into a system, the file is scanned and voice assignment information extracted. This information is stored in a converted file. If desired, the extracted information can be stored using MIDI system exclusives. This allows either any original program change information, or the extracted information, to be used during a performance of the converted MIDI file.

A word processing system is provided having a bidirectional printer with formatting capability. The system includes a word processor having means for outputting a stream of sequential data readable in only one direction. The data comprises blocks of character data representative of the characters to be printed interspersed with blocks of control data representative of the format in which the characters are to be printed; each block of control data has an immediately preceding control block identifier. The bidirectional printer includes means for receiving the stream of sequential data, means for scanning the stream of data and means for inserting a control block identifier at the end of each control block which identifier corresponds to the identifier preceding the control block, whereby the stream of sequential data is made readable in both the forward and reverse directions within the printer.

In a high speed trail printer an improved electronic tab rack is provided. A method and apparatus are disclosed for decreasing the time required to determine the location of the next tab involving accessing a condensed tab rack. The condensed tab rack is set up when the tabs are entered and contains for each byte of the basic tab rack one bit indicating whether or not the associated tab rack byte specifies at least one tab stop position.
