An electrical power (AC / DC) monitoring system remotely monitoring batteries and electrical power systems through a call center, providing continual monitoring, monthly reports, near real time viewing and service response. Modular by design, a plurality of individual input modules, which receive an analog voltage input, convert this signal to a digital format and send the digital signal to a central control which collects the data, then, at scheduled intervals, sends the collected data to a web server which contains the main software for the system. This software performs data comparisons, charts trends, predicts failures, plans and schedules service visits, then archives the data for future references. Alarm notifications are provided to the customer via Email, office phone (land line), cell phone (wireless), PDA, pager, etc. and can also be sent to a service provider to initiate the service response.

A secure processor assuring application software is executed securely, and assuring only authorized software is executed, monitored modes and secure modes of operation. The former executes application software transparently to that software. The latter verifies execution of the application software is authorized, performs any extraordinary services required by the application software, and verifies the processor has obtained rights to execute the content. The secure processor (1) appears hardware-identical to an ordinary processor, with the effect that application software written for ordinary processors can be executed on the secure processor without substantial change, (2) needs only a minimal degree of additional hardware over and above those portions appearing hardware-identical to an ordinary processor. The secure processor operates without substantial reduction in speed or other resources available to the application software. Functions operating in secure mode might reside in an on-chip non-volatile memory, or might be loaded from external storage with authentication.

Workload is programmatically distributed across a set of execution resources. In a multithreaded server environment, response time to end users is improved while increasing the efficiency of software execution and resource usage. Execution time and wait / queued time are tracked, for various types of requests being serviced by a server. Multiple logical pools of threads are used to service these requests, and inbound requests are directed to a selected one of these pools such that requests of similar execution-time requirements are serviced by the threads in that pool. The number and size of thread pools may be adjusted programmatically, and the distribution calculation (i.e., determining which inbound requests should be assigned to which pools) is a programmatic determination. In preferred embodiments, only one of these variables is adjusted at a time, and the results are monitored to determine whether the effect was positive or negative. The disclosed techniques also apply to tracking and classifying requests by method name (and, optionally, parameters).

The invention comprises (i) a compilation method for automatically converting a single-threaded software program into an application-specific supercomputer, and (ii) the supercomputer system structure generated as a result of applying this method. The compilation method comprises: (a) Converting an arbitrary code fragment from the application into customized hardware whose execution is functionally equivalent to the software execution of the code fragment; and (b) Generating interfaces on the hardware and software parts of the application, which (i) Perform a software-to-hardware program state transfer at the entries of the code fragment; (ii) Perform a hardware-to-software program state transfer at the exits of the code fragment; and (iii) Maintain memory coherence between the software and hardware memories. If the resulting hardware design is large, it is divided into partitions such that each partition can fit into a single chip. Then, a single union chip is created which can realize any of the partitions.

A hardware-facilitated secure software execution environment provides protection of both program instructions and data against unauthorized access and / or execution to maintain confidentiality and integrity of the software or the data during distribution, in external memories, and during execution. The secure computing environment is achieved by using a hardware-based security method and apparatus to provide protection against software privacy and tampering. A Harvard architecture CPU core is instantiated on the same silicon chip along with encryption management unit (EMU) circuitry and secure key management unit (SKU) circuitry. Credential information acquired from one or more sources is combined by the SKU circuitry to generate one or more security keys provided to the EMU for use in decrypting encrypted program instructions and / or data that is obtained from a non-secure, off-chip source such as an external RAM, an information storage device or other network source. In a non-limiting illustrative example implementation, the EMU decrypts a single memory page of encrypted instructions or data per a corresponding encryption key provided by the SKU. Although instantiated on the same chip, the CPU core does not have direct access to the SKU circuitry or to encryption key information generated by the SKU.

A system and method to determine the geographic location of a network user based on a plurality of network addresses and a plurality of mapping request information. The method involves receiving a plurality of mapping requests from a plurality of network users identified by a plurality of network addresses. A geographic location of a network user associated with a network address is then derived based on the plurality of network addresses and the plurality of mapping requests. In one embodiment, the network address is an Internet Protocol (IP) address. The method may be implemented, in one embodiment, as part of a system that executes as software on a computer.

Thread pools in a multithreaded server are programmatically adjusted, based on observed statistics from the server's inbound workload. In a multithreaded server environment, response time to end users is improved while increasing the efficiency of software execution and resource usage. Execution time and wait / queued time are tracked, for various types of requests being serviced by a server. Multiple logical pools of threads are used to service these requests, and inbound requests are directed to a selected one of these pools such that requests of similar execution-time requirements are serviced by the threads in that pool. The number and size of thread pools may be adjusted programmatically, and the distribution calculation (i.e., determining which inbound requests should be assigned to which pools) is a programmatic determination. In preferred embodiments, only one of these variables is adjusted at a time, and the results are monitored to determine whether the effect was positive or negative.
