Abstract: A data acquisition and control system includes a controller. The controller includes a CPU and memory, a network switch, a synchronization switch and a power distribution network. The network switch is configurable by the CPU and couples the CPU with an external network, a plurality of directly connected data acquisition modules, and a plurality of networked data acquisition modules. The synchronization switch is configurable by the CPU couples the CPU with the plurality of directly connected data acquisition modules. The power distribution network supplies power to the plurality of directly connected data acquisition modules, and the plurality of networked data acquisition modules. The data acquisition modules comprise a CPU coupled to a local storage with the local storage storing an application program. The data acquisition modules also have a network interface, a programmable logic block, and a sensor interface comprising an excitation output and a data acquisition input.

Abstract: Leak rate testing is an engineering challenge where on the one hand, engineers must meet strict leak rate standards on a wide range of products and systems from semiconductor packages through medical product packaging to chemical storage vessels and liquid/gas handling systems. On the other hand, they have to make the leak testing process low cost and independent of operator whilst in many applications making the process automated and fast as this step may otherwise become a manufacturing bottleneck. Accordingly embodiments of the invention address manufacturing requirements by providing for high accuracy flow based leak testing of large volumes, providing adaptive techniques for use during testing, providing equivalent circuit modeling techniques allowing optimization and parameter extraction to be simulated prior to manufacturing commitment, and providing for the automatic tuning of setup parameters.
