Abstract:
In one example, a system receives, from different sources, data having various formats, the received data is selected and combined in accordance with the invention to create accurate records. Specifically, the inventive system organizes the received data into uniform data records having a predetermined format. The data in the uniform data records is converted, if necessary, to conform to a predetermined nomenclature, resulting in normalized data records. The normalized data records are then processed to extract and/or deduce information desired by users.

Abstract:
The tracking and monitoring system for opencast mines of the present invention enables continuously tracking and monitoring vehicles and moveable equipment in opencast mines using ZigBee-enabled active RFID devices forming a dynamic wireless network among them and other static and mobile ZigBee devices placed at strategic locations. The present invention provides a tracking and monitoring system for opencast mines comprises in combination of ZigBee-compliant devices (programmable to operate as end devices, routers and coordinators by hardware specific embedded software) and wireless sensor network software having various application modules for opencast mines. Use of the system of the present invention would help in maintaining computerized record and analysing the performance of costly shovels and dumpers deployed in opencast mines. This would help in optimising the placement of dumpers with each shovel depending on the change in working and dumping places. This would also help in maintaining computerise attendance of dumper operators and other personnel working in an opencast mine. This would further help in providing warning to the signal man and dumper operator, while dumper approaching close proximity to the signal man. This would help in establishing two-way message communication among the personnel engaged in an opencast mine. This would ultimately help in improving production, productivity and safety in opencast mine.
Abstract:
An apparatus comprising a level shifter circuit and a control circuit. The level shifter circuit may be configured to generate a differential output in response to (i) a first differential input, (ii) a second differential input and (iii) a first supply. The level shifter circuit comprises a first pull down transistor pair operating with the first supply. The control circuit may be configured to generate the second differential input in response to (i) the first differential input and (ii) a second supply. The control circuit generally comprises a second pull down transistor pair operating with the second supply. The first supply has a higher voltage than the second supply.

Abstract:
A compensation circuit for controlling a variation in output impedance of at least one buffer circuit includes a monitor circuit and a control circuit coupled with the monitor circuit. The monitor circuit includes a pull-up portion including at least one PMOS transistor and a pull-down portion comprising at least one NMOS transistor. The monitor circuit is configured to track an operation of an output stage of the buffer circuit and is operative to generate at least a first control signal indicative of a status of at least one characteristic of corresponding pull-up and pull-down portions in the output stage of the buffer circuit over variations in PVT conditions to which the buffer circuit may be subjected. The control circuit is operative to generate a set of digital control bits as a function of the first control signal. The set of digital control bits is operative to compensate the pull-up and pull-down portions in the output stage of the buffer circuit over prescribed variations in PVT conditions.
Abstract:
A method of identifying malicious code based on identifying software executing out of writable memory of the computer system. In one embodiment, the identification of the malicious code occurs when the code accesses a predetermined memory address. This address can reside in the address space of an application, a library, or an operating system component. In one embodiment, the access to the predetermined address generates an exception invoking exception handling code. The exception handling code checks the memory attributes of the code that caused the exception and determines whether the code was running in writeable memory.
