Abstract

A position indicator device for marking the location of an aircraft that has crashed has a buoyant housing containing a radio beacon, a dye dispenser, and a visual beacon. Upon the crash of the aircraft, the buoyant housing is deployed by an air bag ejection system. Upon deployment, a control wire pulls a control pin from a controller, thereby activating the radio beacon, dye dispenser, and visual beacon. The radio beacon immediately alerts emergency personnel that a crash has occurred and can guide the emergency personnel to the scene. The dye dispenser slowly releases a liquid dye that stains the water an easily recognizable color. The visual beacon not only allows crash survivors to find the position indicator device and gather together for survival and rescue, it also allows emergency personnel to find the position indicator device in bad weather or at night.

Claims

1. A position indicator device for marking the location of an aircraft that has crashed, the device comprising:

a buoyant housing containing a battery electronically connected to a controller;

a dye dispenser operably connected to the controller;

a visual beacon operably connected to the controller; and

a means for activating the controller to electronically connect the battery to a radio beacon, the dye dispenser, and the visual beacon.

2. The device of claim 1 wherein the dye dispenser includes a dye container having a supply of liquid dye, the dye container having an ejection conduit, a flow control valve releasing the liquid dye through the ejection conduit in response to a signal from the controller.

3. The device of claim 1 wherein the activating means is a control pin operatively inserted into the side of the position indicator device such that when the control pin is pulled from the position indicator device, the controller activates the radio beacon, the dye dispenser, and the visual beacon.

4. The device of claim 1 wherein the visual beacon is a flashing lamp.

5. The device of claim 1 wherein the visual beacon is at least one flashing LED.

6. A position indicator device for marking the location of an aircraft that has crashed, the device comprising:

a buoyant housing having a watertight internal compartment, the buoyant housing having an ejection conduit and a transparent portion;

the internal compartment containing a battery electronically connected to a controller, the controller being operably connected to a radio beacon, a visual beacon, and a dye dispenser, the dye dispenser being connected to the ejection conduit through a flow control valve, the flow control valve releasing the liquid dye through the ejection conduit in response to a signal from the controller, the visual beacon being positioned adjacent to the transparent portion; and

a means for activating the controller to electronically connect the battery to the radio beacon, the dye dispenser, and the visual beacon.

7. The device of claim 6 wherein the visual beacon is a flashing lamp.

8. The device of claim 6 wherein the visual beacon is at least one flashing LED.

9. The device of claim 6 wherein the activating means is a control pin operatively inserted into the side of the position indicator device such that when the control pin is pulled from the position indicator device, the controller activates the radio beacon, the dye dispenser, and the visual beacon.

10. A method for indicating the position of a crashed aircraft, the method comprising the steps of:

a) providing a position indicator device comprising a buoyant housing containing a battery electronically connected to a controller;

a radio beacon operably connected to the controller;

a dye dispenser operably connected to the controller;

a visual beacon operably connected to the controller; and

a means for activating the controller to electronically connect the battery to the radio beacon, the dye dispenser, and the visual beacon;

b) providing an aircraft having an indicator compartment, a means for ejecting the position indicator device from the indicator compartment and the aircraft when the aircraft crashes, and a means for activating the controller when the position indicator device is ejected from the indicator compartment;

c) positioning the position indicator device inside the indicator compartment;

d) ejecting the position indicator device with the ejecting means upon the crash of the aircraft; and

e) activating the controller with the activator means when the position indicator device is ejected from the indicator compartment, the controller activating the radio beacon, the dye dispenser, and the visual beacon.

11. The method of claim 10 wherein the ejecting means is an air bag actuated by a means of sensing when the aircraft has crashed, wherein the sensing means activates the air bag causing it to expand and eject the position indicator device from the indicator compartment.

12. The method of claim 11 wherein the activating means is a control pin operatively inserted into the side of the position indicator device, the control pin being attached to the aircraft with a control wire such that when the position indicator device is ejected from the aircraft, the control wire pulls the control pin from the position indicator device, thereby causing the controller to activate the radio beacon, the dye dispenser, and the visual beacon.
