The present invention provides a method for modeling the performance of a system comprising computer software operating on computer hardware. In accordance with the present invention, system performance is modeled by fitting non-linear curves to data points for system performance parameters, such as response time and throughput, as a function of load. Data points may be measured in testing may be measured through monitoring a system operating in a production environment. While a variety of non-linear curves may be used in accordance with the present invention, a logarithmic curve may be used to model system throughput and an exponential curve may be used to model system response time. By defining a relationship between throughput and response time a distance may be calculated between the curves, and this distance may be used to determine an optimal load. Additionally, a graph displaying both throughput and response time as a function of load may be displayed to a system operator in a graphical user interface to facilitate the evaluation of system performance.

A disturbance locating system includes a voltage transducer, a current transducer and disturbance energy determination circuitry. The system may also include disturbance power determination circuitry. The voltage transducer couples to an output of a voltage transformer, the output of the voltage transformer representative of a voltage on a line. The current transducer couples to an output of a current transformer, the output of the current transformer representative of the current flowing through the line, the output having a forward reference direction and a behind reference direction. The disturbance energy determination circuitry couples to the voltage transducer and the current transducer. Based upon the inputs received, the disturbance energy determination circuitry determines disturbance energy flowing in the line and estimates a direction of disturbance energy flow with respect to the system as either in front of or behind of the disturbance locating system.

An improved field programmable gate array (FPGA) is provided which includes tab network connectors for interfacing groups of configurable function generators with lower levels of interconnect and for interfacing lower levels of interconnect with higher levels of interconnect. Furthermore, an innovative cluster architecture is utilized which provides fine granularity without a significant increase in configurable function generators. The tab connector network can also be used to route a lower level routing line to a higher level routing line. This is particularly desirable in order to meet the needs for driving a signal along longer routing lines without requiring all signal drivers be sufficiently large to drive a signal along the longest routing line. The connector networks described enable a flexible routing scheme to be implemented in which the routing lines at each level are divided into sets. In addition, the innovative routing hierarchy consisting of the routing lines, block connector tab networks and turn matrices, permits an innovative, space saving floor plan to be utilized that is scalable.

A conditional purchase offer (CPO) management system is disclosed for receiving CPOs from one or more customers, such as airline passengers, and for evaluating the received CPOs against a number of CPO rules defined by a plurality of sellers, such as airlines, to determine whether any seller is willing to accept a given CPO. A CPO is a binding offer containing one or more conditions submitted by a customer for purchase of an item, such as airline travel, at a customer-definied price. A CPO rule is a set of restrictions defined by a given seller, such as an airline, to define a combination of restrictions for which the seller is willing to accept a predefined price. The CPO rules may be securely stored by one or more servers. The CPO management system permits a seller to correct for forecasting errors, if necessary, or other competitive forces which have produced excess capacity, by providing inventory for sale to CPO customers.

Prepaid printing services are obtained and provided using remote and host computers. A card or diskette for printing services is purchased and using a remote computer, the host computer is accessed by e-mail or the like. Application software and printer drivers are downloaded from the host to the remote, and the prepaid printing services are actually installed as a print option on the print menu of the remote computer. Document composition and printing to fulfill the printing services request can be by any conventional techniques, and debiting and invoicing are typically practiced simultaneously with document shipment.

A method and apparatus for displaying, on a display device, a selected page from a print document inserts formatting parameters at the beginning of each page in the data stream representing the print document. The apparatus and method further locate a specified page in the print document, and then display the specified page utilizing the formatting parameters at the beginning of the page. There is no need to process the entire document in a manner similar to that used for printing since each page includes the formatting parameters.

A system and method for generating a class of weighted intensity performance metrics and a class of relative performance metrics for a computer system. Additionally, a method for accumulating data for generating the two classes of performance metrics. A record is generated that is associated with a transaction performed by an application process A.sub.i running on a computer system. A tick count is generated representing a total amount of a resource of the computer system that is consumed by application process A.sub.i for completion of the transaction. Each increment of the tick count represents a unit of consumption of the resource. A performance metric corresponding to a quality of performance of the computer system for application process A.sub.i and related to a metric value M1 is generated based on records and tick counts that are associated with the transaction performed by the application process A.sub.i.

A method of making a phase lock loop circuit is disclosed. The method includes a method of simulating the phase lock loop circuit. The simulation runs on a system for making phase lock loop circuits. The simulation step initializes a reference frequency variable associated with a reference frequency of a phase lock loop circuit. The simulation method also initializes a voltage controlled oscillator (VCO) frequency variable associated with a VCO frequency of the phase lock loop circuit. A phase error is obtained from a frequency error between the reference frequency variable and the VCO frequency variable. The simulation method resets the phase error by a reset phase level when the phase error is approximately the same as a multiple of a reset threshold. When the frequency error changes sign, the phase error is permitted to also change sign. The simulation also determines a loop filter input for the phase lock loop circuit that depends upon the phase error and the frequency error. The simulation method provides a dramatic improvement in simulation time over conventional simulation methods.
