摘要： An oilfield equipment identifying apparatus for tracking selected parameters for each of a plurality of pieces of oilfield equipment adapted to be inserted into a drill string supported by a drilling rig. The drilling rig also supports a drilling device for selectively rotating portions of the drill string to form a well bore. The apparatus comprises a computer loaded with an oilfield equipment database. A reader is provided for inputting into the computer a unique identification code for each piece of oilfield equipment added to the drill string so as to build a grid including a reference to each piece of oilfield equipment. The computer further includes a pipe utilization and identification program for continuously and automatically monitoring the location in the drill string of each piece of oilfield equipment identified in the grid and the cumulative rotating usage and non-rotating usage of each piece of oilfield equipment identified in the grid so as to provide an accurate representation of the historical data of each piece of oilfield equipment identified in the grid.

摘要： The invention enables real time diagnosis of a whole memory region without affecting engine control functions. Judgment is made as to whether an engine is in a prestart condition, or a normal operation condition (engine operating). With prestart, memory diagnosis is performed continuously over the whole region by performing diagnosis with time synchronous jobs, with each job diagnosing a number of bytes obtained from previously determined diagnosis unit bytes multiplied by a set number of cycles. With normal operation, memory diagnosis is performed with time synchronous jobs once in a plurality of cycles, by interrupting the memory being in use at predetermined periods to intermittently perform diagnosis on divided part of the memory each time.

摘要： A programmable method for analyzing the performance of software using a combination of statistical sampling, hardware events and feedback, and a finite state machine execution model. Performance analysis code is integrated with the object code of the software it is analyzing and profiling. Using hardware timers and triggers, the analysis code records timing information at each timer or trigger event, where some events may be the result of stochastic sampling. At certain times during the execution and termination of the software being profiled, results of the profiling are output. Upon the termination of the software being profiled, post processing is optionally performed on the profiling output timing information, and the result of this post processing provides a human readable indication of where the analyzed software spent its execution time. A system for implementing the profiling method in hardware is also described.

摘要： A method verifies that a processor is executing instructions in a proper endian mode when the endian mode is changed dynamically. In accordance with the present invention, a test suite written and compiled in big endian mode is loaded into memory. The test suite is converted to little endian mode and stored back to memory. Next, the processor status is changed from big endian mode to little endian mode, and the test suite is executed. Finally, the results of the test suite are examined to ensure that the processor properly executed the instructions in little endian mode.

摘要： A method, system, and computer readable code for improving stress testing of Web servers. An altered form of client cache is used, enabling more realistic and representative client requests to be issued during the testing process. This altered cache format is referred to herein as a “meta-cache”, and is defined as storing a minimal subset of the information that would typically be cached from a response. This minimal subset is that which enables constructing conditional HyperText Transfer Protocol (HTTP) GET requests. By providing a capability for realistically simulating conditional requests as well as unconditional requests, the stress applied to the server is more representative of the actual traffic load it will experience. By minimizing the amount of information kept in the meta-cache, this realistic simulation is possible without the overhead of a full client cache, and also allows more browsers to be simulated from a particular workstation.

摘要： The invention relates to a method for commissioning a bus system and to a corresponding bus system. A test is carried out preferably after installation of the bus system and before it is actually put into operation to check whether the system is functioning properly. The test can comprise several stages which each test different functional aspects of the bus system. The bus system test can be carried out especially from a distributor or gateway (1) which couples several voltage supply lines (2-4), designed to carry information in addition to a supply voltage, with a central voltage supply line (L, N).

摘要： Improved weakest condition analysis. In one embodiment, a computer-implemented method including first identifying a set of candidates of a computer program that are potentially defective, via a predetermined data flow analysis. In one embodiment, the predetermined data flow analysis may be a static single assignment analysis, or a partial redundancy analysis. Next, each of these candidates is examine via a weakest precondition analysis to determine whether the candidate actually is defective. The end result is a faster analysis, because the weakest precondition analysis is only performed on those candidates that are deemed potentially defective by the initial predetermined data flow analysis performed.

摘要： A computer system for diagnosing and isolating faults in the computer system. A first value is written from the processor using the bus a first address within the address space of a diagnostic state machine. The value is latched in a first register and written from the first register to a second address in the memory. By reading a second value from the memory at second address, the processor compares the second value to the first value to indicate an error if they are different.
