Telemetry system with wireless power receiver and monitoring devices
First Claim
1. A wireless power receiver, comprising:
- a rectifier coupled to an antenna, the antenna configured to receive a wireless power signal, the rectifier configured to convert the wireless power signal to a direct current input signal;
a direct current-to-direct current converter configured to generate a direct current output signal based in part on the direct current input signal and a pulse-width modulation signal;
a pulse modulator configured to adjust an alternating current impedance of the wireless power receiver by modifying, based in part on the direct current input signal, a duty cycle of the pulse-width modulation signal to the direct current-to-direct current converter; and
a monitoring device in communication with the rectifier and the pulse modulator, the monitoring device having one or more sensors and a unique user ID, the one or more sensors acquiring user information selected from of at least one of, a user'"'"'s activities, behaviors and habit information, and ID circuitry at the monitoring device.

Abstract
A wireless power receiver includes a rectifier coupled to an antenna. The antenna receives a wireless power signal, and converts the signal to a direct current input signal. A direct current-to-direct current converter generates a direct current output signal based in part on the direct current input signal and a pulse-width modulation signal. A pulse modulator is configured to adjust an alternating current impedance of the wireless power receiver by modifying, based in part on the direct current input signal, a duty cycle of the pulse-width modulation signal to the direct current-to-direct current converter. A monitoring device is in communication with the rectifier and the pulse modulator. The 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. ID circuitry is at the monitoring device.
