Process agents for process integration
The addition of process agents into an application system allows a much simpler integration between business objects by placing the integrating components into separate, independently updateable process agents.

Thus, a business object may be designed, operated, or updated with complete independence from the surrounding structure of the application system. The logic, application code, and integration components that require specific changes or design in response to changes in the overall application system or real world conditions are placed in the process agent objects, allowing them to be updated, modified or integrated freely without any changes to business objects within the system. |

Partitioning code in program code conversion
A partitioning technique utilized by a translator to divide the subject code space into regions, referred to hereafter as partitions, where each partition contains a distinct set of basic blocks of subject code and corresponding target code. The partitioning technique divides the translator's representation of subject code and subject code translations into non-overlapping regions of subject memory. In this manner, when the subject program modifies subject code, only those partitions actually affected by the self-modifying code need be discarded and all translations in unaffected partitions can be kept. This partitioning technique is advantageous in limiting the amount of target code that must be retranslated in response to self-modifying code operation. In another process, the partitioning technique allows multithreaded subject programs that also involve self-modifying code to perform code modification in a thread-safe manner. |

Computer system storing data on multiple storage systems
During the normal operation state of a computer system 1000, the data stored in a primary storage system 200P is copied to an intermediate storage system 200I via synchronous copying and the data stored in the intermediate storage system 200I is copied to a secondary storage system 200R via asynchronous copying. During the reverse operation state, however, the data stored in the secondary storage system 200R is copied to the intermediate storage system 200I via asynchronous copying and the data stored in the intermediate storage system 200I is copied to the primary storage system 200P via synchronous copying. In this way, practical remote copying can be carried out in a computer system in which three or more storage devices are installed at different locations and connected serially. |

Invoking externally assisted calls from an isolated environment
A method of invoking power processor element (PPE) serviced C library functions on a synergistic processing element (SPE) running in isolated mode. When the SPE initiates a PPE-serviced function, an SPE stub routine allocates a parameter buffer in an open area of a local store (LS) memory within the SPE. The LS memory includes an open area accessible to the PPE, and an isolated area inaccessible to the PPE. The SPE stub routine copies function parameters corresponding to the PPE-serviced function to a buffer within the open area of the LS memory, and writes a message word, which contains an identification variable of the PPE-serviced function and a location variable of the function parameters, to the open area. When execution is temporarily suspended on the SPE, the PPE reads the message word from the open area of the LS memory and executes the PPE-serviced function. |

A database monitoring system identifies a context event command that indicates that a particular context, or session, is beginning. The context event command is a tag command, and includes parameters specifying a context label indicative of a change request. Prior to entering a particular change request, the DBA issues the context event command with the context label as a parameter. The context label is an identifier of the change request to be associated with the set of operations, or commands, resulting from the particular change request. The database monitoring system logs and associates subsequently received commands with the context label in a database access log which is employed for later reconciliation of the operations with the corresponding change request. |

Method and apparatus for functional relationship approximation through nonparametric regression using R-functions
One embodiment of the present invention provides a system that constructs a functional relationship approximation from a set of data points through nonparametric regression. During operation, the system receives a training data set in an n-dimensional space.

The system then logically combines the set of regression primitives to produce a convex envelope F, such that for each point p in the n-dimensional space: (1) F(p)=0, if p is on the convex envelope; (2) F(p)<0, if p is inside the convex envelope; and (3) F(p)>0, if p is outside the convex envelope. The system next obtains the functional relationship approximation by computing an argument of the minimum of F in the n-dimensional space. The system subsequently uses the functional relationship approximation to classify data. |

Multimode fiber outer cladding coupler for multi-clad fibers
A multimode fiber coupler has a structure in which a plurality of tapered pump fibers are coupled laterally to a multi-clad fiber, such as a double clad fiber (DCF). Such coupler is produced by first forming a plurality of tapered pump fibers and positioning them around the multi-clad fiber, thus forming a fiber bundle.

The diverging portions of the pump fibers may be removed from the structure. Also, at the waist, the structure may be cleaved and the portion with the converging pump fibers is then spliced with a multi-clad fiber which is similar or identical to the one in the middle of the bundle. |

Touch panel device
Surface acoustic waves are propagated in a lower-left oblique direction and a lower-right oblique direction from an excitation element located on the upper side of a non-piezoelectric substrate and then received by receiving elements located on the left side and the right side, while surface acoustic waves are propagated in an upper-left oblique direction and an upper-right oblique direction from an excitation element located on the lower side of the non-piezoelectric substrate and then received by the receiving elements located on the left side and the right side. Based on the received results at the two receiving elements, a position of an object in contact with the non-piezoelectric substrate is detected. The sensitivity in a region near the diagonal, which is influenced largely by propagation loss of the surface acoustic waves, is improved by increasing the widths of the electrode fingers of the excitation elements and/or the receiving elements, the number of pairs of the electrode fingers, or the aperture width of comb-like electrodes, according to an increase in the propagation distances of the surface acoustic waves, i.e., toward the region near the diagonal. |

A delay locked loop circuit includes a delay replica model unit for reflecting a delay time of an actual output path to a source clock and outputting the reflected source clock as a delay replica clock, a detector for detecting a remaining time after subtracting a time corresponding to a multiple of a clock cycle of the source clock from a time corresponding to a phase difference between the delay replica clock and the source clock, and a delay locking unit for delaying the source clock for a delay time to synchronize a clock generated by delaying the source clock for the detected remaining time of the detector with a phase of the source clock. |

Phase synchronization for wide area integrated circuits
A circuit and method for synchronized clocking of components such as registers. Registers are clocked by individual component clock signals having the same frequency but potentially different phases due to differing propagation delays. Separate component clock signals are received by registers are brought into phase by evaluating the phases of the component clock signals at the registers, and synchronizing the component clock signal of each register to that of the previous register in a sequence. |

Correlated double sampling circuit and sample hold circuit
A correlated double sampling circuit has a sampling capacitor equally divided into a plurality of portions. In the correlated double sampling circuit, an input signal is sampled at a plurality of sampling points and an averaging switch is closed to obtain an average value of a plurality of sampling values obtained by sampling. High frequency noise superimposed on the input signal is thus reduced and a difference between the average values of the plurality of sampling values obtained by sampling is output. |
