Abstract

A method and apparatus is provided for sensing a given situation such as the presence of operational aircraft for deactivation, or other modification, of a device such as wireless communication circuitry signal transmission circuitry while in the presence of the operational aircraft. The sensing of a situation may be by the presence of a predetermined signal, the arrival at a given location, a measurable change in air pressure and so forth. The sensor circuitry, upon detecting conditions suggestive of operational aircraft, operates to activate, deactivate or otherwise modify the performance of a device while in the presence or immediate vicinity of aircraft or other predetermined situation.

Claims

1. RF transmitting apparatus comprising:

normally OFF_RF signal transmission circuitry;

condition sensing means operable to determine when said RF signal transmitting apparatus is in the immediate vicinity of aircraft; and

modifying means, connected to said RF signal transmission circuitry and said condition sensing means, said modifying means operating, only when each of said condition sensing means determines said RF signal transmitting apparatus is not in the immediate vicinity of aircraft, to alter the signal transmission capability of said RF signal transmission circuitry to an ON condition.

2. RF Transmission apparatus comprising:

sensing means operable to determine when said apparatus is located remote from operational aircraft; and

circuit modifying means, operable in response to a given output from said sensing means, for permitting RF transmissions from said apparatus only when said sensing means determines that said apparatus is physically located where RF transmissions will not adversely interfere with operational aircraft.

3. RF Transmission apparatus comprising:

a circuitry power source;

situation-sensing circuitry operable to provide a RF transmitter turn ON first output signal only while not in the immediate vicinity of a given situation, said situation-sensing circuitry being operable to sense at least a plurality of signals from a list of transponder signals, aircraft cabin pressure measuring signals, received apparatus location signals, accelerometer signals and aircraft engine-generated ultrasonic frequency detected signals; and

modifying means operable to enable the ability to transmit RF signals from said apparatus only while said sensing circuitry is providing said transmitter turn ON first output signal.

4. Operational aircraft-aware apparatus comprising:

a plurality of sensing means operable to provide an output signal operable to activate an RF transmitter only when all of said sensing means provide indications of not being in the immediate vicinity of operational aircraft; and

further means, operable to return said RF transmitter to an inactive state when signals are not being received from any of said sensing means indicative of said apparatus not being in the immediate vicinity of operational aircraft.

5. An apparatus for modifying RF transmission capability in a RFID tag, the apparatus comprising:

sensing means comprising circuitry operable for detecting any of a plurality of signals each indicative of not being in the presence of operational aircraft;

logic circuitry for generating an output signal operable to activate RF signal transmission circuitry only during the presence of all of said plurality of signals; and

switch means, operable in response to said output signal from said sensing means, for activating said RF signal transmission circuitry.

6. RF transmission apparatus comprising:

a plurality of sensing means; and

logic means responsive to outputs of each of said sensing means, said logic means being further operable to permit RF transmissions only after all outputs from said sensing means provide a determination that said apparatus is located remote enough from operational aircraft whereby RF transmissions emitted from said apparatus is unlikely to cause interference with operational aircraft.

7. Operational aircraft-aware apparatus comprising:

at least one programmed computer unit;

a plurality of sensing means, each operable to provide output signals to said at least one programmed computer unit only in response to instructions from said at least one programmed computer unit;

normally non-activated RF transmitter apparatus; and

activation means, operable to activate said RF transmitter apparatus only when all output signals received by said at least one programmed computer unit from said plurality of sensing means logically provide an indication of operational aircraft-aware apparatus not being in the immediate vicinity of operational aircraft.

8. Apparatus as claimed in claim 7 comprising, in addition

a plurality of sensing means, each operable to provide output signals to said at least one programmed computer unit only in response to instructions from said at least one programmed computer unit;

and

means operable to reconfigure sensing means actively used by said programmed computer unit to ascertain aircraft awareness as a function of recently sensed data.

9. Apparatus as claimed in claim 8 wherein battery life is extended through the de-activation of unused sensors.
