Abstract: Enterprise test configuration and data management systems and associated methods are disclosed for test, measurement and automation environments that allow management, configuration and analysis of test systems and associated data across enterprise-wide test operations. These systems and methods are directed to the production process from the test and test station point of view and provides a variety of mechanisms for test configuration and data management for test stations (or automated test equipment (ATEs)) including the capability of managing data about each test station, hardware resources, software resources, test configuration, test steps, acquired measurements, test execution, and/or other information related to the tests, the test stations or the units-under-test (UUT).

Abstract: Network-based methods and systems are disclosed for configuring and building systems and providing systems integration for the test, automation and measurement environment. The methods include internet or intranet-based applications that configure and quote a system or system integration project in response to selection of system features, system components and/or system configurations by a network user. The methods may be implemented as part of a build-to-order internet application.

Abstract: An active leak detector which uses frequency multiplexing to indicate the cation of water leaks. The circuit is composed of any number of satellite leak detectors and a master indicator circuit which monitors all detectors simultaneously. Each detector unit is identified by a unique frequency warning signal which allows the indicator circuit to isolate and display the location of the leak. Only two wires are needed to connect all the detectors to the master indicator as well as supply the necessary power to the detectors.

Abstract: Apparatus for multiplexing a large number of digital signals onto a few aog channels using a level code encoded multiplexer. Each digital signal to be multiplexed is assigned a unique reference level to represent a logical "one", with all digital inputs assigned the same zero ground as a base line for a logical "zero".
