    摘要: The present invention relates to apparatuses, systems, and methods that manage the flow of fluids, such as, for example, water, through pipes. Specifically, the apparatuses of the present invention creates a backward pressure in fluid traversing a pipe when the fluid meets a spring loaded poppet valve, wherein the backward pressure within the pipe provides compression to the fluid effectively compressing entrapped gas bubbles within the fluid. The pressure in front of the poppet valve builds and moves the poppet valve away from a seat allowing the fluid with compressed gas bubbles to flow therefrom, which provides more accurate water meter measurements because less gas is being considered in said measurements. Moreover, the apparatuses of the present invention provide backflow prevention. Systems and methods for managing fluids are further provided.

    摘要: A method for testing an electronic circuit comprises selecting a first log interval, a first log start pattern, a first log end pattern, and a first subset range of LBIST patterns from a plurality of LBIST patterns arranged in an order, wherein each LBIST pattern of the subset range of LBIST patterns causes an associated output of an electronic circuit. The method tests an electronic circuit in a first test by applying to the electronic circuit the first subset range of LBIST patterns sequentially in the order, thereby generating a first plurality of associated outputs. The method stores a first subset of associated outputs based on the first log interval, the first log start pattern, and the first log end pattern. The method compares the subset of associated outputs with known outputs to identify a first output mismatch.

    摘要: The present invention is directed to an improved method, system and apparatus for self-testing an electronic device. A scan latch used in a multi-cycle bus is uniquely operated to generate signal transitions consistent with the normal operating speed of the device. This occurs even when a normal signal transition would not otherwise occur since the multi-cycle bus normally requires a plurality of clock pulses to create such signal transition. The logical states of master and slave clocks associated with test scan logic are used to automatically cause the output of a scan latch to invert its output or switch from its previous state at each rising edge of the slave clock that is not preceded by a master or scan clock. This ensures transitions will appear at the output of the latch consistent with the operating clock speed of the slave clock, and these transitions are detected during an AC test of the device to determine the maximum operation frequency of the device even when the device contains an internal multi-cycle bus.
