Abstract

A wireless power transmission system includes, a transmit antenna which in operation produces a wireless field, an amplifier coupled to the transmit antenna, a load sensing circuit coupled to the amplifier and a controller coupled to the load sensing circuit. A monitoring device has one or more sensors and a unique user ID. The one or more sensors acquire user information selected from of at least one of, a user'"'"'s activities, behaviors and habit information. The monitoring device includes an ID circuitry. A communication interface receives information about the unique user ID when the load sensing circuit indicates the monitoring device is within the wireless field. The indication is created using at least a change in power consumption.

5. The system of claim 4, further comprising:

a second monitoring device with a receive antenna in the wireless field and wherein the communication channel is configured for a peer-to-peer communication between the device and the another device.

6. The system of claim 4, wherein the different communication channel is a wireless technology standard for exchanging data communication channel.

7. The system of claim 1, wherein the controller in operation monitors and processes additional information about another monitoring device with a receive antenna in the wireless field to generate additional notification information.

8. The system of claim 1, further comprising:

a memory coupled to the processor, the memory configured to store at least one of the information about the monitoring device or the notification information.

9. A method for detecting a presence of a monitoring device, comprising:
