REMOTE WAKE-UP SYSTEM SAVES STANDBY POWER

摘要

Increasing numbers of electronic devices implies increasing amounts of consumed electrical power and a greater need to conserve power in electronic devices. For that reason, Faycel Fezai, a hardware engineer with Thales Air Systems, France, and co-researchers from various locations throughout France, propose an efficient RF-based energy-transfer system and RF-to-dc conversion circuit and switch with the ability to "wake up" commercial and industrial electronic devices as needed. The technology employs an integrated emitter and receiver working in the industrial-scientific-medical (ISM) frequency range from 2.40 to 2.48 GHz.
