jacket 100 with an attached distress signal transmitter 101 when submerged in water the buoyant force on the buoy 201 detaches the two detachable connecters 215 216 from the clip 211 so that the buoy 201 can be separated from the clip 211 fig2 b illustrates one example of the preferred embodiments of the present invention when the buoy 201 is detached from the clip and is floating in water 221 the structure of the device is similar to that of fig2 a except that the antenna 202 is now fully extended the buoy 201 would be floating on the surface of the water 221 as shown in fig3 in this way the antenna 202 can stay above the surface of the water to emit clear distress signals the buoy 201 is still connected to the clip 211 through a string 219 so that it will not drift too far away from the person 301 an s o s distress signal is then sent when the buoy 201 is detached from the clip 211 the distress signal also includes the location of the device determined by a g p s so that rescue parties will be able to pinpoint where the signal is coming from the distress signal also can include an identification id code which can help the rescue party know how many people are in danger in addition the device in this example also comprises a water sensor 206 that detects water this water sensor 206 provides a way for the transmitter 101 to differentiate whether a person is truly in distress or whether the signal was sent by accident if the signal were to be sent by accident the transmitter 101 can send a cancel signal to notify that the distress.
