Filter Integrity Testing With Adaptive Flow Check Timing

The patent applies dynamics by transitioning from fixed, static test durations to adaptive, dynamic timing. The check phase duration is no longer predetermined but adjusts in real-time based on flow rate measurements. The system dynamically determines when to terminate the check phase by evaluating whether the measured flow rate has stabilized below the threshold, allowing the test to end as soon as sufficient evidence of filter integrity is obtained, thereby eliminating unnecessary waiting time while maintaining reliability.

The patent implements feedback by continuously monitoring the flow rate during the check phase and using this information to control the test duration. The system measures the flow rate at multiple time points, compares it against the threshold, and adjusts the check phase termination accordingly. This closed-loop feedback mechanism allows the test to adapt to actual filter performance, ending the test early when the flow rate clearly indicates integrity, thus improving efficiency without sacrificing dependability.

The patent applies partial action by performing just enough measurements to achieve the required reliability threshold. Rather than using a fixed excessive duration that guarantees reliability in all cases, the system performs the minimum necessary check phase duration adaptively determined by actual measurements. When the flow rate stabilizes well below the threshold, the system stops checking, having obtained sufficient evidence for reliable determination, thus avoiding unnecessary extension of test time while maintaining dependability.

The patent uses preliminary action by conducting a stabilization phase before the check phase to prepare the system for accurate measurements. During stabilization, the test pressure is applied and the system reaches equilibrium, ensuring that subsequent flow rate measurements during the check phase are reliable from the outset. This preliminary preparation reduces the duration needed during the actual check phase to achieve dependable results, as measurements start from a stable baseline rather than requiring extended observation to establish stability.

The patent applies dynamics by making the test procedure adaptive rather than static. The check phase duration automatically adjusts based on actual filter performance during testing. For filters that quickly demonstrate integrity, the check phase terminates early; for filters requiring longer observation, the check phase extends accordingly. This dynamic adaptation maintains ease of operation because the system autonomously manages the variable timing, presenting a simple interface to the user while internally adapting to different filter scenarios.

The patent uses parameter changes by allowing the check phase duration parameter to vary based on measured flow rate characteristics. Rather than fixing this parameter beforehand, the system modifies it in real-time based on whether the flow rate stabilizes quickly or requires longer observation. This parameter adaptation enhances versatility across different filter types and performance scenarios while maintaining operational simplicity, as the parameter adjustment is automated and transparent to the operator.
