Emergency beacon with encoded warning
First Claim
1. An emergency beacon device, comprising:
- a microprocessor, where said microprocessor is configured to receive electronic data, generate distress message bit strings with embedded bit sequences in the format dictated by COSPAS-SARSAT, and convert generated bit strings to an analog RF signal;
a user control interface having a plurality of manual actuators, where said interface is configured to activate the beacon device and transmit electronic data representing a secret message to said microprocessor upon manual actuation of one or more of said actuators;
where the actuation of said actuators in a first preset sequence causes the beacon device to transmit to said microprocessor a first secret message and the actuation of said actuators in a sequence other than said first preset sequence causes the beacon device to transmit to said microprocessor a second secret message;
a GPS receiver configured to transmit electronic data representing the position coordinates of the beacon device to said microprocessor;
where the transmission of said first secret message to said microprocessor causes the generation a first bit string having a first embedded bit sequence, where said first bit string is in the format dictated by COSPAS-SARSAT and said first embedded bit sequence communicates that the user who actuated the interface is authentic and safe and the transmission of said second secret message to said microprocessor causes the generation a second bit string having a second embedded bit sequence, where said second it bit string is in the format dictated by COSPAS-SARSAT and said second embedded bit sequence communicates that the user who actuated the interface may be in danger; and
a radio transmitter configured to receive electronic data representing the RF signal from the microprocessor and broadcast said RF signal, said RF signal being the analog form of any bit string generated by the microprocessor.

Abstract
A personal locator beacon (PLB) that is used to transmit a radio frequency emergency distress signal. The PLB contains a GPS receiver to determine the exact global positioning coordinates of the beacon. The transmitted distress signal contains a security message that is represented through at least one bit. This bit is embedded into the standard bit string that is transmitted and can warn of impending danger at the beacon location, such as a hostage situation. The beacon is triggered through different varieties of user interfaces that utilize assorted combinations of actuators and numeric keypads. Another bit can also be embedded into the standard bit stream to represent whether or not the beacon is used by the military.

2. The method of transmitting security information through an emergency beacon device, comprising:
-
providing a plurality of manual actuators, where said actuators are configured to activate the beacon device and receive user input; forming a digital distress message in the format dictated by COSPAS-SARSAT, said distress message having an embedded secret message, where the actuation of said actuators in a first preset sequence causes the distress message to contain a first secret message and the actuation said actuators in a sequence other than said first preset sequence causes the distress message to contain a second secret message and, sending the distress message, in analog form, through a RF transmitter. - View Dependent Claims (3, 4, 5, 6, 7, 8)
