Publication number: 20100305792Abstract: A system for dynamically reconfiguring high power energy storage of a hybrid electric vehicle is described. The system includes a fault detector, a switch network and a controller. The fault detector is configured to detect a fault condition of one or more energy storage modules of the vehicle energy storage. The switch network is configured to electrically bypass one or more faulty energy storage modules. The controller is configured to determine a faulty energy storage module. The controller determines that current flow between the vehicle energy storage and the hybrid electric vehicle is below a minimum threshold and reconfigures operation controls to operate the vehicle energy storage according to a second configuration that accounts for the electrically bypassed faulty energy storage module. The controller also resumes operation of the vehicle energy storage according to the second configuration.Type: ApplicationFiled: May 29, 2009Publication date: December 2, 2010Applicant: ISE CORPORATIONInventors: Michael D.

Patent number: 5617568Abstract: A system and method to provide native support in a distributed computing environment distributed file system for an operating system's extended file attributes. Such attributes remain invisible in the namespace which the operating system's distributed file system clients may access. A directory of the form .*.sub.-- for a file in DFS namespace is created for which extended attributes (EA) are required, with a subdirectory thereunder whose name is that of the file. Extended attributes are filed under this .*.sub.-- directory having filenames of the attributes' names. Provision is made for discriminating EAs and for efficiently accessing total EA size and number of critical EAs, by cumulating and storing them in an additional file under the subdirectory.Type: GrantFiled: December 14, 1994Date of Patent: April 1, 1997Assignee: International Business Machines CorporationInventors: Michael B.

Patent number: 5274758Abstract: A user/PC interface system is described which enables the creation and performance of a synchronized audio/visual story on the PC. The interface enables the initial storage of a plurality of visual images. Then, it enables the creation of an audio presentation which includes labels and time indications, certain of which are employed for synchronization purposes. The system is responsive to a label to execute a predetermined command upon the appearance of the label in the audio presentation. The PC is then operated to perform the audio presentation, that performance automatically causing the display of visual images upon the occurrence of labels and time indications.An improved, table-based authoring system is also described for preparation of both the above noted audio and visual presentations. The system relies upon columnar presentations of a tabular form, each column indicating a separate control function (or comment) relating to the audio/visual presentation.Type: GrantFiled: December 28, 1992Date of Patent: December 28, 1993Assignee: International Business MachinesInventors: Bradley J.

Patent number: 5249289Abstract: A system and method for use in a digitized audio data editing system for efficiently resequencing the audio data having indexes thereto. During resequencing, an audio index range table of such indexes is constructed. The table provides indications of consecutive index ranges of previously processed indexes. By traversing the table during resequencing to determine if a current index is a duplicate of any previously processed index corresponding to a previously copied audio segment, the necessity to compare each index with every index previously copied over is thereby avoided, which otherwise becomes increasingly inefficient as more indexes are copied over and thus the number of indexes to compare expands. Time required to process a resequence is accordingly significantly reduced.Type: GrantFiled: September 28, 1989Date of Patent: September 28, 1993Assignee: International Business Machines CorporationInventors: Howard C. Thamm, Michael D. Wilkes

Patent number: 5208421Abstract: 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.Type: GrantFiled: November 1, 1990Date of Patent: May 4, 1993Assignee: International Business Machines CorporationInventors: Ronald J.

Patent number: 5054360Abstract: A method and apparatus are disclosed for simultaneously outputting digital audio and MIDI synthesized music utilizing a single digital signal processor. The Musical Instrument Digital Interface (MIDI) permits music to be recorded and/or synthesized utilizing a data file containing multiple serially listed program status messages and matching note on and note off messages. In contrast, digital audio is generally merely compressed, utilizing a suitable data compression technique, and recorded. The audio content of such a digital recording may then be restored by decompressing the recorded data and converting that data utilizing a digital-to-analog convertor. The method and apparatus of the present invention selectively and alternatively couples portions of a compressed digital audio file and a MIDI file to a single digital signal processor which alternately decompresses the digital audio file and implements a MIDI synthesizer.Type: GrantFiled: November 1, 1990Date of Patent: October 8, 1991Assignee: International Business Machines CorporationInventors: Ronald J.
