Patent number: 6549349Abstract: Methods and systems for detecting and correcting for undesirable vibrations impacting the servo systems in data storage devices. A detection technique is provided wherein a detection filter is configured to scan a position signal of the servo system across a range of frequencies, and, at each respective scanned frequency, record an amplitude associated therewith. The recorded amplitudes are examined to determine whether any exceed a threshold, thereby locating a peak frequency of the vibration. Using the detected peak frequency of the vibration, a corrective filter is configured to operate about the peak frequency of vibration, thereby reducing its impact on the position signal in the servo system.Type: GrantFiled: September 18, 2001Date of Patent: April 15, 2003Assignee: International Business Machines CorporationInventors: Sri Muthuthamby Sri-Jayantha, Arun Sharma, Hien Phu Dang, Naoyuki Kagami, Yuzo Nakagawa, Akira Tokizono, Isao Yoneda

Patent number: 6453207Abstract: A complex industrial process is operated via computer control. Process control data regarding multiple process control variables is collected, along with output data regarding one or more process output properties. One or more of the process control variables is altered for a predetermined time in order to determine which of the process control variables are affecting the one or more process output properties.

Patent number: 6342173Abstract: Low-density, high service temperature polymer foam is extruded by heating a crystalline polymer resin above its crystalline melt point to melt the resin, selecting a blowing agent combination, combining the blowing agent combination with the resin to create a mixture, cooling the mixture to a temperature approaching a freezing temperature for the mixture, and extruding the foam through a die. The blowing agent combination is made up of 50 to less than 100 mole percent of a first blowing agent having a boiling temperature at STP of greater than 310° K, and more than 0 to 50 mole percent of a second blowing agent having a boiling temperature at STP of less than 310° K. The blowing agent combination has an equilibrium solubility vapor pressure in the polymer of less than 45 atm at the foaming temperature and greater than or equal to 1 atm at the glass transition temperature.Type: GrantFiled: March 10, 2000Date of Patent: January 29, 2002Assignee: Genpak, L.L.C.Inventor: Walter R.

Patent number: 6273697Abstract: A crystalline polymer resin, such as poly(ethylene terephthalate), is heated to melting. One or more blowing agents is selected wherein at least one of the blowing agents has a boiling point greater than the glass transition temperature for the resin and less than the forming temperature, such as the temperature of the mold used to form the useful article. The blowing agent(s) and resin are combined to create a mixture with a blowing agent concentration sufficient to produce a theoretical sheet foam density of less than 0.4 g/cm3. The mixture is cooled to a temperature approaching the freezing point of the mixture, and then extruded into a substantially uniform closed cell polymer foam sheet of density less than 0.4 g/cm3. The extruded sheet is then cooled by direct contact with a cooling surface at a surface temperature below the glass transition temperature such that the blowing agent(s) condenses and the sheet has a density of greater than 0.4 g/cm3 and a sheet crystallinity of less than 15%.Type: GrantFiled: September 28, 1999Date of Patent: August 14, 2001Assignee: Genpak, L.L.C.Inventor: Walter R.

Patent number: 6003091Abstract: A quiesced and synchronous distributed data processing system includes a primary node, a secondary node and a switch between the primary and secondary nodes. The TOD for the primary node is set depending on the system. The invention sets the TOD for the switch based on the TOD of the primary node. The primary node then verifies the switch TOD. If verified, the TOD for the secondary node is set, based on the TOD of the primary node. Finally, the secondary node self-verifies its TOD.Type: GrantFiled: April 8, 1997Date of Patent: December 14, 1999Assignee: International Business Machines CorporationInventors: Robert Francis Bartfai, Derrick LeRoy Garmire, Jay Robert Herring, Francis Alfred Kampf, Nicholas Paul Rash, Kevin John Reilly, Craig Brian Stunkel

Patent number: 5894570Abstract: A self-timed link between two elements in a computer system is initialized. Each element sends an initialization request to the other. If successfully received, the elements exchange signals with oscillation-free segments over multiple clock cycles. If successful, the elements indicate to each other that initialization is complete. Optionally, a link operation parameter can be sent with the initialization complete indication for post-initialization link control.Type: GrantFiled: April 8, 1997Date of Patent: April 13, 1999Assignee: International Business Machines CorporationInventors: Kathy Sue Barkey, Derrick LeRoy Garmire, Harold Edgar Roman, Daniel Gerard Smyth

Patent number: 5844917Abstract: An adapter card in a computer system includes an application specific integrated circuit (ASIC) and a field programmable gate array (FPGA) coupled to the ASIC. Random data is provided to the ASIC logic function(s) by control of the FPGA, which is configured by a programmable logic device on the card and coupled thereto. The logic function(s) of the ASIC is then exercised with the random data, and the output is compared with expected output by the system to determine if there are any errors. The determination is made based on a signature produced by a multiple input shift register (MISR) within the ASIC, based on the output data from the logic function(s). The FPGA can then be reconfigured for normal adapter card functions.Type: GrantFiled: April 8, 1997Date of Patent: December 1, 1998Assignee: International Business Machines CorporationInventors: Gerard M.
