First Claim
Patent Images
1. Distress beacon installed onboard a vehicle comprising a plurality of VHF transceivers, said beacon comprising:
- a transmitter stage, which transmits a distress signal when said beacon is activated;
a receiver stage for continuous listening of a distress frequency; and
a diplexer connected to said transmitter stage and to said receiver stage for connecting one of these stages to an antenna, said receiver stage being connected to a computer in the vehicle, which activates a discrete signal and triggers an alarm to vehicle crew members when a distress signal is received by the receiver stage on said distress frequency, and which communicates with a tuning device of said VHF transceivers, when an alarm is triggered in order to preselect said distress frequency on this tuning device such that when vehicle crew members want to listen to said distress frequency, they have only to validate the distress frequency on one of said VHF receivers.

5. Method for reception of a distress signal on a distress frequency by a receiver stage of a vehicle which comprises a plurality of VHF transceivers, wherein a distress beacon, capable of transmitting a distress signal when it is activated, is installed onboard said vehicle and wherein said beacon comprises said receiver stage and a detection module connected to the output of said receiver stage, said method comprising:
-
continuous listening of the distress frequency using said receiver stage;
detection by the detection module of the reception of a distress signal on the distress frequency;
activating a discrete signal when such a distress signal is received;
signaling an alarm to vehicle crew members;
communicating with a tuning device of said VHF transceivers, when an alarm is signaled in order to preselect said distress frequency on this tuning device; and
validating by the vehicle crew members of this distress frequency on one of said VHF receivers. - View Dependent Claims (6, 7, 8, 9)
