Abstract: A method, system and apparatus for the extensible and unobtrusive performance monitoring and measurement for scripts executing through a script engine. A script performance monitoring and measurement system can include a script engine programmed to execute a provided script and a script processor configured to provide a script to the script engine for execution. Importantly, the system can include a performance monitor disposed between the script processor and the script engine.

Abstract: A solution for managing one or more problems in a software component is provided. The solution includes generating an identifier for each problem based on a call stack for the execution of the software component when the problem occurs. The identifier and a text message for the problem can be displayed to a user. The user can use the identifier to obtain information on the problem and/or one or more updates that address the problem. In one embodiment, the identifier comprises a hash value of the call stack, which is likely to result in a unique value for each possible call stack. In this manner, the identifier will likely provide a unique identifier for each problem.

Abstract: A voltage controlled current source provides a load current through a load impedance which is a function of an input voltage and is independent of the impedance value of the load impedance. The voltage controlled current source includes a high input impedance unity gain instrumentation amplifier and a resistor connected in series with the load impedance so that current flows through the resistor and the load impedance. The instrumentation amplifier receives the input voltage at its inverting input and receives a load voltage representing the voltage across the load impedance produced by the load current at its noninverting input. The instrumentation amplifier subtracts the input voltage at the inverting input from the load voltage at the noninverting input and multiplies by a gain of one to produce an output voltage at its output. The resistor and the load impedance are connected in series between the output of the amplifier and a reference voltage (e.g.
