UHESILO: Capacitor-Integrated Sustain (CIS) Reservoir + Phase-Synchronous Nudge

CIS adds a small energy reservoir and a gentle, timing-aware “nudge” to the UHESILO oscillator so it can run continuously on an ultra-slow, ultra-quiet trickle of power. The reservoir smooths the input; the controller estimates where the oscillator is in its cycle and adds tiny boosts near the turning points, where they disturb timing the least. If, on average, the incoming trickle meets or beats the total power the system needs (including electronics and leaks), the reservoir won’t run down and the oscillator can keep going indefinitely. All electrical paths are filtered and enclosed so there’s effectively no net electromagnetic energy leaking out of the cage during operation. Why it matters Indefinite operation via buffering. A slow, steady trickle is time-shifted by the reservoir; when average input ≥ average use, the system sustains without draining. Low phase disturbance. Nudges are applied at the quietest moments in the motion (near turn-around), and a “parametric” option exists for specialized cases. Graceful holdover. If the trickle dips below needs, the reservoir provides predictable run-time before a safe shutdown Metrology hygiene. The “zero-flux cage” design keeps the sustain path electromagnetically quiet and auditable. What’s inside this document Elements & ports: the oscillator, a storage capacitor as reservoir, a DC-quiet trickle input, a micro-injector, and a low-power controller. Energy & power balance: how trickle-in, injection-out, control overhead, and leakage set the reservoir’s state-of-charge over time. Per-cycle injection law: a simple, timing-locked rule to keep amplitude on target while minimizing timing noise; includes an optional “twice-per-cycle” variant. Indefinite vs. finite operation: conditions for continuous sustain and a clear procedure for estimating holdover when input power falls short. EM hygiene & acceptance tests: isochrony sweeps, ring-down to verify loss budget, zero-flux checks, and an audit that tallies trickle-in against injected energy. Parameter guidance & notes: nanowatt-class totals with heavy duty-cycling; filtering, returns, and slew-limited edges for clean behavior. Limitations & scope.CIS is presented as a conceptual and experimental design. It is not a finished device. Real-world performance requires careful fabrication, calibration, and independent testing.
