Abstract

A wireless power receiver includes a rectifier coupled to an antenna which is configured to receive a wireless power signal, and convert the wireless power 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.

Claims

1. A wireless receiver system, comprising:

a rectifier coupled to an antenna, the antenna configured to receive a wireless signal, the rectifier configured to convert the wireless 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 receiver system 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 pulse modulator, wherein the monitoring device coupled to the antenna, the monitoring device including a microphone and sensors to determine air quality, sound level, sound quality, light quality and ambient temperature near a person; and

an accelerometer or other motion detection device configured to detect a person'"'"'s movement information, the accelerometer or other motion detection device and the monitoring device are configured to assist to determine a person'"'"'s movement sounds, a person'"'"'s sleep information and sleep behavior information, the microphone configured to record the person'"'"'s movement sounds, the person'"'"'s sleep information and sleep behavior information detected by the accelerometer or other motion detection device, the recording of the person'"'"'s movement sounds, the person'"'"'s sleep information and sleep behavior information is disabled in response to the accelerator detection of the person'"'"'s movement information, wherein the accelerometer or other motion detection device configured to cause the microphone to stop recording the person'"'"'s movement sounds when the person'"'"'s movement sounds are not directed to a sleep related parameter.

2. The system of claim 1, further comprising:

a user interface or an activity manager.

3. The system of claim 2, wherein the user interface includes an entry field to enter a name of an activity.

4. The system of claim 2, wherein the activity manager in operation manages and monitors a user activity.

5. The system of claim 2, wherein the activity manager in operation provides a user reminder when to start an activity.

6. The system of claim 2, wherein the activity manager in operation provides a user reminder when to stop an activity.

7. The system of claim 2, wherein the activity manager in operation provides includes a calendar of when one or more activities should be performed.

8. The system of claim 2, wherein the activity manager in operation provides for a user to select an activity to be tracked.

9. The system of claim 2, wherein the system further provides for a monitoring of environmental conditions.

10. The system of claim 9, wherein in response to the monitoring of environmental conditions, an alert can be provided to a user as to a desirability of engaging in an activity.

11. The system of claim 9, wherein at least one of the environmental conditions is weather.

12. The system of claim 2, wherein the activity manager is in communication with a mobile device.

13. The system of claim 2, wherein the system is in communication with a weather service.

14. The system of claim 2, wherein the system in operation further provides a prompt to a user as a reminder of an activity.

15. The system of claim 2, wherein the system further includes an activity profile database.

16. The system of claim 2, wherein the activity manager includes an activity profile database.
