Field notes
The page frames preload loss as a maintenance problem addressed through inspection, scheduled retightening, or locking hardware, then proposes collecting vibration energy at the fastener. Its described sequence is harvest, store, and restore; the company says the mechanism remains in prototype development. A prototype tensioner is listed as being in manufacture with an estimated arrival date of November 27, 2026, while performance data is reserved for qualified partners under NDA.
