Efficiency monitor for inductive power transmission
First Claim
1. An efficiency monitor for monitoring power transmission by an inductive power outlet, the inductive power outlet comprising at least one primary coil wired to a power supply, for inductively coupling with a secondary coil wired to an electric load, the efficiency monitor comprising:
- at least one input power monitor for measuring input power delivered to the primary coil;
at least one output power monitor for measuring output power received by the secondary coil;
at least one processor for determining an index of power-loss; and
at least one communication channel for communicating the input power and the output power to the processor;
wherein;
the output power monitor is incorporated into an inductive power receiver unit comprising at least one signal transmitter for transmitting a signal to a receiver incorporated in the power outlet, the signal carrying data pertaining to the output power; and
the transmitter comprises;
an ancillary load selectively connectable to the secondary inductive coil,a modulator for modulating a bit-rate signal with an input signal to create a modulated signal, anda switch for intermittently connecting the ancillary load to the secondary inductive coil according to the modulated signal.

Abstract
An efficiency monitor for monitoring the efficiency of power transmission by an inductive power outlet. The efficiency monitor includes an input power monitor, for measuring the input power delivered to the primary coil, and an output power monitor, for measuring the output power received by the secondary coil. The input and output powers are used by a processor to determine an index of power-loss. A circuit breaker may be used to disconnect the inductive power outlet in case of excessive power loss.
