WIRELESS DEVICE DETECTION USING MULTIPLE ANTENNAS SEPARATED BY AN RF SHIELD
First Claim
1. An apparatus used for determining whether a mobile device is transmitting from within a human operated machine, the apparatus comprising:
- a first antenna positioned within an at least partially enclosed operator area of a human operated machine;
a second antenna positioned external to the operator area of the human operated machine;
a radio frequency shield positioned between the first antenna and the second antenna; and
a processing module that is in electrical communication with the first antenna and the second antenna, wherein the processing module is configured to;
receive a first signal received from the first antenna and a second signal received from the second antenna, anddetermine, based upon an analysis of the first signal and the second signal, whether a radio frequency generating device is active within the at least partially enclosed operator area.

Abstract
A system comprising one or more interior antenna(s) positioned within an at least partially enclosed operator area of a human operated machine and one or more exterior antenna(s) positioned on an external portion of the human operated machine, with a radio frequency shield positioned between the interior antenna(s) and the exterior antenna(s), is usable with a processing module electrically connected with the antennas for analyzing signals received from the antennas to determine whether a radio frequency generating device is active within the at least partially enclosed operator area.

16. A method for detecting the transmission of a radio frequency generating device that is located within an operator area of a human operated machine, the method comprising:
-
receiving, at a processing module, a first signal from a first antenna positioned within an at least partially enclosed operator area of a human operated machine; receiving, at the processing module, a second signal from a second antenna positioned exterior to the at least partially enclosed operator area of the human operated machine, wherein a radio frequency attenuator is positioned between the first antenna and the second antenna relative to a signal originating from within the operator area; receiving the first signal received from the first antenna and the second signal received from the second antenna; and determining, based upon an analysis of the first signal and the second signal, whether a radio frequency generating device is active within the at least partially enclosed operator area. - View Dependent Claims (17, 18, 19, 20, 21)

22. A computer storage device having stored computer-executable instructions which, when executed by at least one hardware processor, implement a method for detecting the use of a radio frequency generating device by within an operator area of a human operated machine, wherein the method includes:
-
receiving, at a processing module, a first signal from a first antenna positioned within an at least partially enclosed operator area of a human operated machine; receiving, at the processing module, a second signal from a second antenna positioned exterior to the at least partially enclosed operator area of the human operated machine, wherein a radio frequency attenuator is positioned between the first antenna and the second antenna relative to a signal originating from within the operator area; comparing the first signal received from the first antenna and the second signal received from the second antenna to correlate the first and second signals as being a same signal at different strengths; and determining, based upon the comparison of the first signal and the second signal and relative strengths of the first and second signal, whether a radio frequency generating device corresponding to the first and second signals is active within the at least partially enclosed operator area.
