Water-borne beacon detection system for missing persons

1. A search system, comprising:

a search beacon detector; and

code configured to instruct a processor in a mobile device to execute steps of:

configuring a Bluetooth radio in the mobile device with a first connection configuration associated with the search beacon detector and configuring a WiFi radio in the mobile device with a second connection configuration associated with the search beacon detector;

for a device in a sleep mode wherein the WiFi radio in the mobile device is not powered but wherein the Bluetooth radio of the mobile device is receptive to a connection attempt, directing the device to exit the sleep mode upon receiving a connection attempt from the search beacon detector to the Bluetooth radio using the first connection configuration; and

upon receiving the connection attempt, causing WiFi the radio to power up and attempt to connect to the search beacon detector using the second connection configuration;

wherein the search beacon detector is adapted to detect each connection attempt associated with the first and second connection configurations and associate a geographical location with the connection attempt using the second connection configuration.

2. The search system of claim 1 wherein the code is configured to instruct the processor to provide a user interface on a display of the mobile device and user input directing the device to enable a rescue mode.

3. The search system of claim 1 wherein the code is configured to cause the processor to enter low power mode after a period of inactivity of the mobile device.

4. The search system of claim 3 wherein the code is configured to instruct the processor to providing a user interface allowing a user to modify the period of inactivity.

5. The search system of claim 1 wherein the code is configured to instruct the processor to providing a user interface on a display of the mobile device allowing the user to enter registration information uniquely identifying the mobile device to a rescue agency.

6. The search system of claim 1 wherein the second connection configuration includes at least one SSID which is unique to a rescue agency.

7. The search system of claim 6 further including configuring the WiFi radio with a plurality of connection configurations including a plurality of SSIDs.

8. The search system of claim 7 wherein the code is configured to instruct the processor to output a registration of the mobile device from the search subject to a data store of the rescue agency.

9. A search system, comprising:

providing an application executable on a processor of a mobile device, including code configured to instruct the processor to execute steps of:

configuring a Bluetooth radio in the mobile device with a first connection configuration associated with a search beacon detector and configuring a WiFi radio in the mobile device with a second connection configuration associated with the search beacon detector;

responsive to a rescue trigger, directing the device to enter a sleep power mode while awaiting a connection attempt from the Bluetooth radio, the sleep power mode comprising wherein the WiFi radio in the mobile device is not powered but wherein the Bluetooth radio of the mobile device is receptive to a connection attempt; and

upon receiving the connection attempt to the Bluetooth radio, powering up the WiFi radio and causing the WiFi radio to attempt to connect to the search beacon detector using the second connection configuration associated with the search beacon detector;

the search beacon detector associating a geographical position with the mobile device upon the attempt to connect to the search beacon detector using the second connection configuration; and

a waterproof device container, the waterproof mobile device container adapted to be coupled with a user of the mobile device and position the mobile device of a user at a location near the surface of water when the mobile device and the container are in water.

10. The search system of claim 9 wherein the container is a pocket on a personal floatation device located in a position near the shoulder of a user wearing the device.

11. The search system of claim 9 wherein the container is a pouch tethered to a personal floatation device and adapted to position the device near the surface of the water.

12. The search system of claim 10 wherein the system further includes a solar charging panel and a connection allowing the mobile device to receive power from the solar charging panel.
