A system for analyzing the performance of an interactive voice response (IVR) system operates to record from end to end plural calls from callers. For a plurality of calls, the system codes and annotates an agent-caller interaction, including a topic discussed during the interaction; detects a routing operation of the IVR system by detecting a sequence of events in the IVR system, with reference to a call-flow file that summarizes the call-flow model of the IVR system, for each call; and cross-tabulates routing information obtained from the detected sequence of events with results from the coded and annotated agent-caller interactions.

The present invention allows administrators of conference equipment, remotely localized from the ordinary managing interface, to execute simple commands for solving a problem that may have occurred during a conference or at conference set up. This is provided by a parser translating user terminal commands transmitted from the user terminal (e.g. a cellular phone) of the system administrator to Conference Management System codes, which are executed on the conference equipment in question from the Conference Management System. The present invention also allows system administrators to be alerted by a message (e.g. SMS) at any errors occurring during a conference or conference set up, and to correct the errors by responding to the alert without the need of addressing the equipment in which the errors occur

Various embodiments of the present invention are directed to efficient methods for virtual-machine monitors to detect, at run time, initial attempts by guest operating systems and other higher-level software to access or execute particular instructions or values corresponding to the particular instructions, that, when accessed for execution, need to be emulated by a virtual-machine monitor, rather than directly accessed by guest operating systems. In certain embodiments of the present invention, the virtual-machine monitor assigns various guest-operating-system-code-containing memory pages to one of a small number of protection-key domains. By doing so, the virtual-machine monitor can arrange for any initial access to the memory pages assigned to the protection-key domains to generate a key-permission fault, after which the key-permission-fault handler of the virtual-machine monitor is invoked to arrange for subsequent, efficient access or emulation of access to the protected pages. In alternative embodiments, protection domains can be implemented by using page-level access rights or translation-lookaside-buffer entry fields.

Memory demands of large-memory applications continue to remain one step ahead of the improvements in DRAM capacities of commodity systems. Performance of such applications degrades rapidly once the system hits the physical memory limit and starts paging to the local disk. A distributed network-based virtual memory scheme is provided which treats remote memory as another level in the memory hierarchy between very fast local memory and very slow local disks. Performance over gigabit Ethernet shows significant performance gains over local disk. Large memory applications may access potentially unlimited network memory resources without requiring any application or operating system code modifications, relinkling or recompilation. A preferred embodiment employs kernel-level driver software.

Code can be injected into a compiled application through the use of probes comprised of instrumentation code. Probes can be implemented in a custom high level language that hides low level instruction details. A directive file contains instructions on injecting a probe into a compiled application. An instrumentation engine reads these instructions and injects the probe into the compiled application at the appropriate injection points. Multiple probes can be used, and can be stored in a probe library. Each probe can inject code into the application at, for example, a package, class, method, or line of the compiled application. Calls can also be made to external runtime libraries. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

The invention provides tools and techniques for running pre-boot code on a computer from a file stored in a file system on the computer. The pre-boot code may include an operating system which is not otherwise installed on the system. For instance, the pre-boot code may be used to boot a DOS operating system on a computer which lacks a DOS hard disk partition. The pre-boot code may contain code to perform operations that are difficult to perform after the operating system is booted, such as code for monitoring the boot process to help debug it. The pre-boot code is obtained from the file without using booted file system code, and is then executed. The code may be obtained by redirecting floppy drive I / O to read the pre-boot code from a copy in memory, or to read it as needed from one or more files on the hard disk.

Coding of received audio signals and the resulting application of electrical stimuli applied to electrodes used in a cochlear implant system are disclosed together with a method of fitting this new coding strategy. One of the aims is to place specific stimulation representing pitch by applying near threshold electrical stimuli with limited and focussed excitation fields. A range of stimulation rates and a minimal range of current levels above threshold are used for creation of a dynamic loudness percept for a cochlear implant recipient. Another aim is to disclose a coding scheme based on a model of physiological measures (i.e. refractoriness, adaptation, spread of activation field, spatiotemporal acoustical cochlear activation patterns and spontaneous activity) to estimate the proportions of available excitable auditory neurons close to the electrodes available for stimulation. The spectral bands formed from the pre-processing of incoming audio signals are weighted by these proportions of excitability to control place, timing, rate and current level of electrical stimuli applied to the electrodes available in the array.
