| 20110290247 | METHODS AND DEVICES FOR RESCUING A DISTRESSED DIVER - The invention discloses devices and methods for identifying a diver in distress and initiating a rescue response. Specifically, embodiments of the present invention allow for identification of a diver who is not breathing properly and in response giving local stimuli to allow the diver to response. Should he/she not respond, the instant invention will initiate steps to bring the diver back to the water surface and alert others as to his/her need of assistance. | 12-01-2011 |

| 20080202510 | DRAIN VALVE ASSEMBLY - An on-board oxygen generating system is provided, which includes an air supply duct, a breathing gas duct, and an oxygen generator fluidly coupled between the air supply duct and the breathing gas duct. The oxygen generator is configured to enrich the oxygen content of air flowing from the air supply duct to the breathing gas duct. A drain valve assembly is fluidly coupled to the air supply duct and configured to move between: (i) an open position wherein condensation may drain from the air supply duct, and (ii) a closed position. | 08-28-2008 |
| 20080257342 | Valve for dive mask - A valve mounted on a dive mask is disclosed. The mask has a closed window frame, a soft skirt extending rearward from the window frame for defining a space between itself and the face of a diver wearing the mask, and one or two windows defined by the window frame. The valve is flexible, tubular and has a first opening at one end in communicating with the space, and a second opening at the other end. The second opening is blocked in an inoperative position and is adapted to open to expel water or air therethrough by increasing pressure in the space or by pressing both sides of the valve. | 10-23-2008 |
| 20090101143 | Valve Unit for a Rebreather Apparatus - The present invention concerns a valve unit for a rebreather apparatus that recycles gas exhaled by a user. The valve unit includes a housing | 04-23-2009 |
| 20100083958 | PERSONAL PROTECTIVE HOOD HAVING THERMOPLASTIC NECKDAM - This invention relates to protective hoods, and in particular personal protective hoods which surround an individual's head and protects the individual from contact with Chemical-Biological-Radiological-Nuclear (CBRN), smoke, noxious fumes, and products of combustion, such as carbon monoxide. The protective hoods contain neck dams that seal against a person's neck and are formed from thermoplastic elastomers or polyolefins. | 04-08-2010 |
| 20140150780 | PROTECTIVE BREATHING APPARATUS INHALATION DUCT - An improved protective breathing apparatus having a vent hole or one way valve incorporated into the inhalation duct so that the breathing apparatus can safely vent and release a pressure differential during the opening of the storage bag from vacuum storage. The use of an air pressure relief mechanism prevents the rupture of the duct and preserves the integrity of the device. | 06-05-2014 |
| 20160107006 | HELMET FOR ANESTHESIA - A helmet for anesthesia, adapted to keep confined anesthetic gases and to administer them in a non-invasive fashion to a patient laying on an operating table, allowing to provide oxygen and/or anesthetic gases through tubes and fast access to the patient's head in case of emergency is described. The helmet has a lower half-shell and an upper half-shell, the lower half-shell being anatomically shaped to receive and support the nape and the neck of the laying patient, the upper half-shell and the lower half-shell having fastening means for fastening one to the other and being configured to be fitted one to the other and to the neck or torso of the patient to form a substantially airtight enclosure for enclosing head of the patient, at least one inlet port for gas supply and at least one outlet port for gas evacuation being on the lower half-shell and/or the upper half-shell. | 04-21-2016 |
| 20160121146 | RESPIRATORY PROTECTION HOOD - A hood comprising a flexible envelope and a reservoir of oxygen comprising a calibrated outlet orifice that leads into the internal volume of the envelope, the outlet orifice being closed off by a removable stopper, characterized in that the reservoir of pressurized oxygen comprises two independent storage compartments, a first compartment of which communicates with the outlet orifice and a second compartment of which is isolated from the outlet orifice via a sealed partition provided with a member for opening the partition, the opening member being switchable between a first configuration which prevents fluidic communication between the second compartment and the outlet orifice and a second configuration that allows fluidic communication between the second compartment and the outlet orifice, the opening member being sensitive to the pressure difference between the second compartment and the first compartment and being configured to automatically switch from the first to the second configuration when the pressure difference between the second compartment and the first compartment is less than a given threshold. | 05-05-2016 |

| 20130327325 | MEDICAL/SURGICAL PERSONAL PROTECTION SYSTEM INCLUDING A HELMET, A HOOD AND FASTENING SYSTEM FOR HOLDING THE HOOD TO THE HELMET SO THE RADIUS OF CURVATURE OF THE HOOD FACE SHIELD VARIES ALONG THE FACE SHIELD - A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. The hood/toga has a transparent face shield that is flexible. A fastening assembly holds the face shield to the helmet so that, at the top of the face shield the shield has a relatively wide radius of curvature. Extending downwardly from the top of the face shield the radius of curvature of the shield becomes smaller. Providing the face shield with this geometry reduces the extent to which the person wearing the helmet and hood/toga of this invention is subjected to glare. | 12-12-2013 |
