Abstract: Source entities with initially predefined properties for service modeling are presented in a library for user selection as service modeling entities. An automated computer process expediter copies user selected ones of the source entities from the library into a computer readable storage medium providing a services layer. The copying generates instances in the services layer of the selected service modeling source entities, such that the services layer instances at least initially include the initially predefined properties of their respective source entities. The automated computer process expediter maintains the properties of the selected ones of the source entities, including maintaining the selected source entities' properties independently of changes made in a first change mode to the properties of the service modeling entity instances, which are in the services layer, so that the user may change the properties of the layer service modeling instances.

Abstract: A plurality of heap dump requests associated with an operating virtual machine (VM) program is received from a VM profiler interface module at a heap dump request processing module. In response to receipt of each heap dump request at the heap dump request processing module, a dynamic modifiable library identified within a dynamic modifiable configuration file is loaded into a memory, where the dynamic modifiable library comprises instructions associated with processing a current heap dump request. The instructions associated with processing the current heap dump request are executed. The dynamic modifiable library is unloaded from the memory. A plurality of heap dump files and a plurality of object movement event files generated by execution of the instructions are analyzed. A memory leak associated with the operating VM program is automatically identified based upon the analyzed plurality of heap dump files and the plurality of object movement event files.

Abstract: An invention is disclosed for analyzing memory leaks occurring in Java Virtual Machine (JVM) data storage, consisting of a dynamically modifiable JVM “profiler” and an “object tracker” tool for analyzing the output from the profiler. Specifically, a method and system is disclosed for programming a JVM profiler used to analyze and correct memory leaks in stored data heaps, consisting of a program segment (or “stub”) initialized by the JVM application program interface to determine the parameters to be passed to the main profiler memory leak analysis program logic, which is then initialized by the stub to examine a minimal number of “heap dumps” in order to identify data elements or objects for the existence and/or correction of memory leaks. Updated information on data elements or objects can be requested from the profiler as needed by use of the object movement tracking option to record the details of subsequent changes in data memory storage status once a heap dump has been obtained.

A system of one or more reflectors is operatively associated with a transponder and may be formed out of any sort of radio frequency reflective material. The reflector system can enhance reception or transmission of radio waves by or from the transponder. The reflector system may also be used to provide for selective coupling of the radio frequency transponder with a base station, user- or vehicle-supported reader, or the like based on relative orientation. In addition, the reflector system may be used to selectively reflect particular radio waves.
