Method and apparatus for covertly detecting and reporting a distress condition in a vehicle control cabin
First Claim
1. A method of covertly detecting and reporting a distress condition in a control cabin of a vehicle, the cabin having designated areas expected to be occupied by respective operators under normal operating conditions of the vehicle, comprising:
- (a) attaching to each operator a transponder tag configured to wirelessly transmit a response signal, unique to the operator to which it is attached, responsive to an interrogator signal;
(b) wirelessly transmitting interrogator signals into the designated areas;
(c) attempting to detect response signals, if any, from the transponder tags; and
(d) if all of the response signals are concurrently not detected, then wirelessly transmitting a distress signal from the vehicle.

14. A method of covertly detecting and reporting a distress condition in a cockpit of an airplane, the cockpit having designated areas expected to be occupied by respective pilots under normal operating conditions of the vehicle, comprising:
-
(a) attaching to each pilot a transponder tag configured to wirelessly transmit a response signal, unique to the pilot to which it is attached, responsive to an interrogator signal;
(b) wirelessly transmitting interrogator signals into the designated areas;
(c) attempting to detect response signals, if any, from the transponder tags; and
(d) if all of the response signals are concurrently not detected, then wirelessly transmitting a distress signal from the aircraft.

15. A system for covertly detecting and reporting an emergency condition in a control cabin of a vehicle, the cabin having designated areas expected to be occupied by respective operators under normal operating conditions of the vehicle, comprising:
-
transponder tags each configured to (i) be attached to a respective operator, and (ii) wirelessly transmit a response signal, uniquely encoded to identify the operator to which it is attached, responsive to an interrogator signal;
interrogator units, each including a transmitter configured to wirelessly transmit an interrogator signal, a receiver configured to detect a wireless response signal if received, and a controller, coupled with the receiver, configured to issue a result message indicating whether a response signal is detected;
a control module configured to issue a distress message when the result messages issued from all of the interrogators indicate that all of the response signals are not detected concurrently; and
a radio configured to wirelessly transmit the distress message. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A system for covertly detecting and reporting an emergency condition in a cockpit of an airplane, the cockpit having designated areas, between a cockpit control console and pilot seats, expected to be occupied by respective pilots under normal operating conditions of the airplane, comprising:
-
transponder tags each configured to (i) be attached to a respective pilot, and (ii) wirelessly transmit a response signal, uniquely encoded to identify the pilot to which it is attached, responsive to an interrogator signal;
interrogator units each mounted to either a respective portion of the cockpit control console that faces a respective pilot seat, or a respective pilot seat, each of the interrogator units including a transmitter configured to wirelessly transmit an interrogator signal, a receiver configured to detect a wireless response signal from a corresponding one only of the transponder tags, and a controller, coupled with the receiver, configured to issue a result message indicating whether the response signal is detected;
a control module configured to issue a distress message when the result messages issued from all of the interrogators indicate that all of the response signals are not detected concurrently; and
a radio configured to wirelessly transmit the distress message.
