Latest Patents

Chuo's latest patents showcase her expertise in developing advanced RF technologies. The first patent, titled "Low-power, long-range RF localization system and method," presents a novel approach for non-line-of-sight localization between RF-enabled devices. The system involves a transmitting node that sends an RF ranging signal at a first carrier frequency, which is modulated with a symbol. A reflecting node receives this signal, converts it to a second carrier frequency, and retransmits it, all while simultaneously receiving the original signal. The localizing node, in turn, identifies the symbol in the frequency domain to compute the distance between itself and the reflecting node.

The second patent, "Low power high gain radio frequency amplifier for sensor apparatus," details a wireless communication device designed for sensor applications. This device incorporates an antenna, a driver circuit with cross-coupled transistors, and a bias circuit that operates in both transmit and receive modes. By employing different bias currents for each mode, the device oscillates the antenna in transmit mode and amplifies incoming signals in receive mode, enhancing overall communication capabilities.
