Flotation apparatus
First Claim
1. An apparatus comprising:
- a body having an outer wall defining a first gas chamber and a second gas chamber separated by an inner wall;
a water pressure activated latching valve having a sealing end disposed in the first gas chamber, wherein the sealing end is configured to seal an opening disposed in the inner wall to prevent gas disposed in the first gas chamber from escaping into the second chamber until the pressure activated valve is activated by water pressure;
an inflatable membrane disposed in the second chamber, wherein when the pressure activated latching valve is activated by water pressure communicated though an opening in the outer wall to an exterior side of the membrane, the pressurized gas disposed in the first gas chamber is communicated though the opening in the inner wall to inflate the membrane, wherein in response to the pressurized gas, the inflatable membrane extends outside the body though the opening in the outer wall; and
a transceiver configured to provide a location wireless signals in response to an external input or activation of inflatable membrane.

Abstract
A method and apparatus is provided to support a plurality of objects such as keys with an inflatable apparatus when the inflatable apparatus is exposed to a body of water. In one embodiment, an inflatable apparatus provides an attachment member such as a key ring to attach objects such as keys to the inflatable apparatus. The inflatable apparatus is capable of inflating from a compact shape to an expanded shape upon contact with water. In the expanded shape, the inflatable apparatus provides sufficient buoyancy to support the objects coupled therewith and float the objects to the surface of the water for retrieval by a user. In situations where the weight of the object exceeds a buoyancy limit, the inflatable apparatus can extend a marker buoy to assist in the retrieval of the objects. In other embodiments, the inflatable apparatus includes a wireless transmit a wireless location signal.

10. An automatic inflatable apparatus, the apparatus comprising:
-
a body having a first chamber and a second chamber; a movable wall slidably disposed in the first chamber; a shaft attached to the movable wall on a first end; an internal wall disposed within the body to separate the first chamber from the second chamber, wherein the internal wall includes a first opening sized to allow the shaft to pass therethrough; a water dissolvable member disposed in the first opening, wherein another end of the shaft distal the first end abuts the water dissolvable member, wherein when the dissolvable member is not dissolved by water, the movable wall is held by the dissolvable member in a first position, wherein when the water dissolvable member is dissolved by water, the shaft is capable of passing through the first opening to position the movable wall in a second position; and an inflatable member disposed in the first chamber between the movable wall and a wall of the first chamber, wherein when the dissolvable member is not dissolved, the inflatable member is enclosed in the first chamber by the movable wall, wherein when the dissolvable member is dissolved, at least a portion of the inflatable member expands from the first chamber to an exterior position though a second opening in a second wall of the body. - View Dependent Claims (11, 12, 13, 14)

15. An inflatable apparatus configured to hold keys and other items, the apparatus comprising:
-
an enclosure; an inflatable membrane disposed within the enclosure; an inflation activation apparatus configured to move from a ready state to an activation state when the apparatus is submerged in a body of water, wherein in the activation state the inflatable membrane expands through an opening in an outer wall of the enclosure under gas pressure to provide buoyancy for the apparatus in the body of water; and a latching mechanism configured to prevent the inflation activation apparatus from returning to the ready state. - View Dependent Claims (16, 17, 18, 19, 20)
