The U.S. Patent and Trademark Office recently notified WatchGuard Video that they have issued the company a patent on the "Intelligent Standby" technology pioneered in WatchGuard Video's High Fidelity Wireless Microphone system. WatchGuard's "Intelligent Standby" technology is a sophisticated approach to power management that extends the standby battery life of the HiFi wireless microphone up to 25 days from a single charge, compared to 12 hours with most conventional systems, according to the company. This is the second patent WatchGuard Video has been awarded on its HiFi microphone system.
This patent, titled "Method and System of Extending Battery Life of a Wireless Microphone Unit" (U.S. Patent #8,712,362 B2), outlines a system that applies two separate compression methods to achieve very high audio quality, while using extremely low power consumption, and simultaneously keeping the wireless unit in sync with the base receiver over long periods of inactivity.
