TRANSMISSION-GUARD SYSTEM AND METHOD FOR AN INDUCTIVE POWER SUPPLY
First Claim
Patent Images
1. An inductive power transfer system comprising at least one inductive power outlet operable to transfer power to an inductive power receiver, said inductive power outlet comprising:
- a platform for supporting said inductive power receiver;
at least one primary inductive coil embedded in said platform, said primary inductive coil;
a driver wired to said primary inductive coil and operable to provide a driving voltage across said primary inductive coil;
wherein;
said primary inductive coil is configured to form an inductive couple having a characteristic resonant frequency with at least one secondary inductive coil wired to an electric load, said secondary inductive coil associated with said inductive power receiver; and
said driving voltage oscillates at a transmission frequency significantly different from said characteristic resonant frequency of said inductive couple.

Abstract
A transmission-guard is disclosed for preventing an inductive power outlet from transmitting power in the absence of an inductive power receiver. A transmission lock is associated with an inductive power outlet and a transmission key is associated with an inductive power receiver. The transmission lock is configured to prevent a primary inductor from connecting to the power supply unless triggered by a release signal via the transmission key
