|
| 8. | One of the patents,'Single Pickup Frequency Control For String Instrument', led to legal wrangling with Fender.
|
| 9. | Load-frequency control operates with a response time of a few seconds to keep system frequency stable.
|
| 10. | Unlike synchronous motors, induction generators are load-dependent and cannot be used alone for grid frequency control.
