Abstract

A personal monitoring system includes one or more passive biometric sensors and a communication device. A passive biometric sensor is operable to sense a body condition of a body in accordance with a sense signal at a sense frequency to produce sensed data of a body condition. The passive biometric sensor is further operable to transmit an e-field signal via the body regarding the sensed data, wherein the e-field signal is in accordance with an e-field transmit/receive frequency. The communication device is operable to receive the e-field signal via the body. The communication device is further operable to recover the sensed data from the received e-field signal.

Claims (90)

1. A personal monitoring system comprises:

a passive biometric sensor operable to:

sense a body condition of a body in accordance with a sense signal at a sense frequency to produce sensed data of the body condition; and

transmit an e-field signal via the body regarding the sensed data, wherein the e-field signal is in accordance with an e-field transmit/receive frequency; and

a communication device operable to:

receive the e-field signal via the body; and

recover the sensed data from the received e-field signal.

2. The personal monitoring system of claim 1 further comprises:

a second passive biometric sensor operable to:

sense a second body condition of the body in accordance with a second sense signal at a second sense frequency to produce second sensed data of the second body condition; and

transmit a second e-field signal via the body regarding the second sensed data, wherein the second e-field signal is in accordance with a second e-field transmit/receive frequency; and

the communication device is further operable to:

receive the second e-field signal via the body; and

recover the second sensed data from the second received e-field signal.

3. The personal monitoring system of claim 1 , wherein the communication device further comprises:

an external wireless communication module for wireless communications with a computing device.

4. The personal monitoring system of claim 1 further comprises:

the communication device is further operable to transmit input data to the passive biometric sensor via a transmit e-field signal; and

the passive biometric sensor is further operable to:

receive the transmit e-field signal via the body; and

recover the input data from the received transmit e-field signal.

5. The personal monitoring system of claim 1 , wherein the body condition comprises one or more of:

heart rate;

respiration;

perspiration;

temperature;

hydration; and

a neurological system.

6. The personal monitoring system of claim 1 , wherein communication is further operable to:

assign the sense frequency and the e-field transmit/receive frequency to the passive biometric sensor.

7. The personal monitoring system of claim 1 further comprises:

the communication device as a component of a computing device.

8. A personal monitoring system comprises:

a passive foot force sensing unit operable to:

sense a body force of a body in accordance with a sense signal at a sense frequency to produce sensed force data of a body condition; and

transmit an e-field signal via the body regarding the sensed force data, wherein the e-field signal is in accordance with an e-field transmit/receive frequency; and

a communication device operable to:

a personal coordinate unit operable to:

receive the signal regarding the signal strength;

transmit an e-field signal via a body regarding the signal strength, wherein the e-field signal is in accordance with an e-field transmit/receive frequency; and

a communication device operable to:

receive the e-field signal via the body; and

recover the signal strength from the received e-field signal.

15. The personal monitoring system of claim 14 further comprises:

a second passive body position marker operable to:

receive the RF signal;

determine a second signal strength of received RF signal; and

transmit, via the RF signal, a second signal regarding the second signal strength;

the personal coordinate unit is further operable to:

receive the second signal regarding the second signal strength;

transmit a second e-field signal via the body regarding the second signal strength, wherein the second e-field signal is in accordance with a second e-field transmit/receive frequency; and

the communication device is further operable to:

receive the second e-field signal via the body; and

recover the second signal strength from the received second e-field signal.

16. The personal monitoring system of claim 14 , wherein the communication device further comprises:

an external wireless communication module for wireless communications with a computing device.

17. The personal monitoring system of claim 14 further comprises:

the communication device is further operable to transmit input data to the passive body position marker and/or the personal coordinate unit via a transmit e-field signal; and
