  • Patent number: 6487455
    Abstract: An operating system for distributed industrial controllers ensures the completion of enrolled application programs within a predetermined time span as is required for robust industrial control by preallocating dynamic and static hardware resources on a per application basis and in a manner that ensures execution of the application within the necessary time constraints. Portions of the distributed operating system may be distributed at particular hardware resources to provide necessary modeling for those hardware resources in making the commitments to resource bandwidths.

  • Patent number: 6480750
    Abstract: A controlling system having a controller which acts on a controlled system as a function of a manipulated variable and a number of controller parameters is intended to provide a given control quality and a given control response in all operating states of the controlled system. For this purpose, the response characteristic of the controlled system is determined in a given time window during operation of the controller by comparing a wavelet transformation of the temporal response of the manipulated variable with a wavelet transformation of the temporal response of a controlled variable of the controller. An instant assigned to the respective wavelet transformation is detected, and the or each controller parameter is set as a function of the response characteristic.

  • Patent number: 6480749
    Abstract: Performance measurement and analysis of local exchange carrier interconnections. Performance measurements can be used to establish that an incumbent local exchange carrier (“ILEC”) is providing interconnections to one or more competitive local exchange carriers (“CLEC's”) that are at least equal in quality to the interconnections provided to itself. Performance measurements are defined to measure the timeliness, accuracy and availability of the interconnections provided to the CLEC'S. A performance measurement is based upon performance data that us collected from one of the ILEC's processes (preordering, ordering, provisioning, collocation, billing, maintenance and repair, emergency 911, operator service/directory assistance and trunk blockage). A performance report is defined to specify the types of performance measurements and dimensions that are included, as well as the reporting period.

  • Patent number: 6477441
    Abstract: A numerical control system having a built in personal computer (PC), is made up of an interrupt generation circuit in an NC section for generating an interrupt in the NC section when a power off switch is pressed, PC termination acknowledgement means in the NC section for sending a termination request to a PC section, acknowledging a termination notification from the PC section, and requesting a DS output circuit to turn off the power of a power unit, a PC power down handling section in the PC section for forcibly terminating an application program and an operating system in the PC section after receiving the termination request sent from the PC termination acknowledgement means in the NC section, and a BIOS section for checking that the operating system is terminated and sending a termination notification to the NC section. Thus, in the numerical control system having a built-in PC, the power is turned off soundly without destroying an external storage unit such as a hard disk storage unit.

  • Patent number: 6473656
    Abstract: Local technology modules automatically execute given functions as part of process automation. Each technology module has a memory storing module-specific information about the respective function of the technology module and its tie-in to a measuring point, open- and closed-loop control system. During an initialization phase, this information is transmitted to a central communication device, where it is stored for access by an operator communication and monitoring device. It can thus automatically add the information to its operator communication and monitoring interface.

  • Patent number: 6466827
    Abstract: Rapid development of control programs for programmable logic controllers controlling semi-standard combinations of equipment is provided by the creation of relay ladder logic objects prestored in the programmable logic controller and invoked only as needed for the particular application. The inability of a programmable logic controller to provide for the memory management mechanisms necessary for true software object instancing is overcome by pre-storing the objects in the programmable controller with pre-allocated variable addresses. Connection of the used objects to I/O is provided by a mapper program also written in relay ladder code. The objects are associated with particular pieces of equipment and provide inter-machine control for that equipment while high level control program executed on a standard computer which controls the objects through reading and writing of object variables.

  • Patent number: 6463341
    Abstract: An orthogonal functional basis method for function approximation is disclosed. Starting with the orthogonal least squares method, a new subset selection method for selecting a set of appropriate basis functions is explained where, instead of picking a subset from a given functional basis, the subset is selected from a combination of functional basis evolved from a set of heterogeneous basis functions. The method results in a more efficient neural network.

  • Patent number: 6449526
    Abstract: In a grinding machine a measurement arrangement is provided for the monitoring of the processing of a work piece, especially to make tools. The measuring arrangement uses, preferably, combined transmitted-light and incident-light based techniques so that both the edges and surfaces and depressions on the work piece are detected precisely. The automatic measurements makes it possible to automatically adjust the process parameters for the grinding process so that changes due to temperature drift, mechanical imprecisions of the mechanical system of the grinding machine or wear on the grinding disks are automatically compensated. This makes possible production of relatively large batches within very close tolerances and with high precision.

  • Patent number: 6445962
    Abstract: An auto-tuner for use in tuning a control element in a process control network having distributed control functions includes a first tuning element located in the field device in which the control element is operating and a second tuning element located in a different device that communicates with the first device via a communication network. The first tuning element controls the operation of the control element during the dynamic data capture phase of an auto-tuning procedure, collects data during this phase of the auto-tuning procedure and determines one or more process characteristics from the collected data. The first tuning element then communicates the determined process characteristics to the second tuning element via the communication network.
