Patent number: 8341302Abstract: A method for automatically configuring an electronic device, such as a mobile telephone, is disclosed. According to one embodiment, the method includes receiving at an electronic device a command identifying first data and automatically determining a property of the identified first data. The method further includes automatically identifying an executable from the determined property and operating on the identified first data using the identified executable.Type: GrantFiled: February 14, 2004Date of Patent: December 25, 2012Assignee: Nokia CorporationInventors: Claus Pedersen, Jacob Hansen

Patent number: 8108570Abstract: A state of an input/output (I/O) operation in an I/O processing system is determined. A request for performing the I/O operation is received from an I/O operating system at a channel subsystem and forwarded to a control unit controlling an I/O device for executing the I/O operation. After a predetermined amount of time passes without receiving indication from the control unit that the I/O operation is completed, an interrogation request is received at the channel subsystem from the I/O operating system for determining the state of the I/O operation. An interrogation command is sent from the channel subsystem to the control unit. A response is received from the control unit, the response indicates a state of the I/O device executing the I/O operation, a state of the control unit controlling the I/O device executing the I/O operation, and the state of the I/O operation being executed.Type: GrantFiled: February 14, 2008Date of Patent: January 31, 2012Assignee: International Business Machines CorporationInventors: Harry M. Yudenfriend, Daniel F. Casper, John R. Flanagan, Matthew J. Kalos, Dale F. Riedy, Louis W. Ricci, Roger G. Hathorn, Gustav E. Sittmann, Ugochukwu C. Njoku, Catherine C. Huang, Scott M. Carlson

Patent number: 7363395Abstract: A method according to one embodiment may include determining, at least in part, by an intermediate device at least one communication protocol via which at least one storage device connected to the intermediate device is capable of communicating. In this embodiment, the intermediate device may be capable of controlling, at least in part, by the intermediate device, at least one data stream coming from the at least one storage device in accordance with at least one communication protocol. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.Type: GrantFiled: December 31, 2003Date of Patent: April 22, 2008Assignee: Intel CorporationInventor: Pak-Lung Seto

Patent number: 7325081Abstract: A hardware-controlled data protection scheme can be used on a device providing buffering between two different protocols, especially where at least one of the protocols does not use fixed length blocks. A fixed block size is arbitrarily imposed on the data in order to calculate a cyclical redundancy code (CRC) for the block. Block sizes are restricted to a value of 2n, e.g., 2, 4, 8, 16, etc. The device is able to time-share and to receive or send data on more than one port while sharing the CRC engine between the ports. Intermediate values of the CRC for a given port are temporarily saved in a CRC register file. As a block of data for a given port is completed, a final CRC value for the block is saved to a CRC random access memory (RAM) located on the device and the entry in the register file is cleared. When the data is then output from the device, the CRC for the block is recalculated and checked against the saved value to be sure that they match.Type: GrantFiled: March 24, 2004Date of Patent: January 29, 2008Assignee: LSI Logic CorporationInventor: David Thomas

Patent number: 7313637Abstract: Disclosed herein is a computer system provided with a mechanism for connecting a single port disk to an active server and the disk to a standby server when in a fail-over processing. An “add_pci” command issued from a clustering program is used to let a control program change the allocation of a PCI slot while an interruption signal issued to a standby server permits an ACPI processing routine to hot-add a PCI card that includes the disk unit on the subject guest OS.Type: GrantFiled: December 5, 2003Date of Patent: December 25, 2007Assignee: Hitachi, Ltd.Inventors: Tsuyoshi Tanaka, Keitaro Uehara, Yuji Tsushima, Naoki Hamanaka, Daisuke Yoshida, Yoshinori Wakai

Patent number: 7277969Abstract: On the basis of a period of a timing signal, a signal propagation delay in a device unit, signal propagation delay in the timing signal bus and the data bus, and a setup time of another device unit or a device connected to the data bus, a timing at which noise caused by active connection of the first device to the data bus is propagated to the other device unit or the device is computed in a step of noise propagation computing, and on the basis of the timing computed in the step of noise propagation computing, a connection timing at which the first device unit is connected to the data bus. With thes two steps, a noise caused by active connection of a device unit does not affect other device units and devices connected to the same data bus.Type: GrantFiled: December 27, 2005Date of Patent: October 2, 2007Assignee: Fujitsu LimitedInventor: Ryohei Nishimiya

Patent number: 7269672Abstract: A design method for a bus system comprising a noise propagation computation step and a connection timing computation step. Based on the cycle of a timing signal, a signal propagation delay in a device unit, signal propagation delays in a timing-signal bus and a data bus, and a setup time in the device unit or device connected on the data bus, the noise propagation computation step computes timing at which, when the device unit is connected on the data bus being active, noise propagates to other device units other than the connected device unit or to the device connected on the data bus. Based on the timing computed in the noise propagation computation step, the connection timing computation step computes connection timing at which the device unit is connected on the data bus.Type: GrantFiled: February 13, 2004Date of Patent: September 11, 2007Assignee: Fujitsu LimitedInventor: Ryohei Nishimiya

Patent number: 7072131Abstract: A storage device in which file data is divided into multiple blocks for storage on a recording medium. The storage device includes an additional data storing section for storing additional data to be recorded on the recording medium in association with the data to be written, a position determining section for determining recording positions on the recording medium where the blocks should be respectively written, based on the additional data, and a block writing section for writing the respective blocks on the recording positions on the recording medium determined by the recording position determining section. The additional data thus defines a gap length between blocks of recorded data. During a read operation, if the gap length does not comport with the additional data, then an error is assumed.Type: GrantFiled: October 20, 2003Date of Patent: July 4, 2006Assignee: International Business Machines CorporationInventors: Tomoaki Kimura, Satoshi Tohji
