Abstract

A personal voltage detection system comprises a garment to be worn by a user and carrying a plurality of electric field sensors each facing a different direction. Each sensor comprises a transducer sensing electric field in transmitting a wireless signal representing field strength for an associated direction. An alert device is in operative communication with the plurality of sensors and comprises a control configured to monitor field strength for each sensor and determine existence of an alarm condition responsive to field strength being above a pre-select level and to generate an alarm signal indicating the associated direction of the alarm condition.

First claim

The invention claimed is:

1. A personal voltage detection system comprising:
a plurality of wearable electric field sensors each adapted to be worn on an outer side of a user's body each facing a different direction, each sensor comprising a transducer sensing electric field and transmitting a wireless signal representing field strength for an associated direction; and
an alert device in operative communication with the plurality of sensors and comprising a control configured to monitor field strength for each sensor and determine existence of an alarm condition responsive to field strength being above a preselect level and to generate an alarm signal indicating the associated direction of the alarm condition.

2. The personal voltage detection system of claim 1 wherein the alert device further comprises an audio output generating an audio signal responsive to the alarm condition.

3. The personal voltage detection system of claim 1 wherein the alert device comprises an indicator associated with each direction and the control illuminates the indicator for the associated direction of the alarm condition.

4. The personal voltage detection system of claim 3 wherein the alert device comprises a video display including a graphic display with the indicators for each direction.

5. The personal voltage detection system of claim 1 wherein the alert device comprises a smart phone.

6. The personal voltage detection system of claim 1 wherein the alert device includes an indicator to indicate communication status with the plurality of sensors.

7. The personal voltage detection system of claim 1 wherein the alert device comprises an indicator associated with each sensor and the control varies each indicator to indicate communication status for the associated sensor.

8. The personal voltage detection system of claim 1 wherein the sensors and the alert device communicate using short-wavelength radio waves.

9. The personal voltage detection system of claim 1 wherein the sensors and the alert device are battery powered.

10. A personal voltage detection system comprising:
a garment to be worn by a user and carrying a plurality of electric field sensors each facing a different direction, each sensor comprising a transducer sensing electric field and transmitting a wireless signal representing field strength for an associated direction; and
an alert device in operative communication with the plurality of sensors and comprising a control configured to monitor field strength for each sensor and determine existence of an alarm condition responsive to field strength being above a preselect level and to generate an alarm signal indicating the associated direction of the alarm condition.

11. The personal voltage detection system of claim 10 wherein the alert device further comprises an audio output generating an audio signal responsive to the alarm condition.

12. The personal voltage detection system of claim 10 wherein the alert device comprises an indicator associated with each direction and the control illuminates the indicator for the associated direction of the alarm condition.

13. The personal voltage detection system of claim 12 wherein the alert device comprises a video display including a graphic display with the indicators for each direction.

14. The personal voltage detection system of claim 10 wherein the alert device comprises a smart phone.

15. The personal voltage detection system of claim 10 wherein the alert device includes an indicator to indicate communication status with the plurality of sensors.

16. The personal voltage detection system of claim 10 wherein the alert device comprises an indicator associated with each sensor and the control varies each indicator to indicate communication status for the associated sensor.

17. The personal voltage detection system of claim 10 wherein the sensors and the alert device communicate using short-wavelength radio waves.

18. The personal voltage detection system of claim 10 wherein the sensors and the alert device are battery powered.
