Patent number: 8755839Abstract: A personal multimedia communication system and network for emergency services personnel includes a plurality of personal communication systems linked together and to a base station in a network. Each personal communication system includes a PDA device mounted on a PASS control console, a video camera mounted on the PDA device, a GPS unit, a microphone, and other electronic devices. The various electronic devices are all communicatively connected to the PDA device. Data from the various devices may be collected in the PDA device and wirelessly transmitted to any other node or device in the network, including other personal communication devices. Each personal communication device may serve as a repeater, thus providing a wireless communications link between a device located out of range of the base station.Type: GrantFiled: May 23, 2008Date of Patent: June 17, 2014Assignee: STI Licensing Corp.Inventors: Craig Michael Parkulo, Wesley McChord Barbee, Jerald Robert Malin, Jeffrey Lynn Landis, Matthew Shannon

Patent number: 7866340Abstract: A universal pressure reducer is provided for a self-contained breathing apparatus. The universal pressure reducer includes an inlet, a reducer module in fluid communication with the inlet, a pneumatic alarm mechanism, and a pneumatic transfer valve assembly that controls the actuation of the alarm mechanism by controlling the flow of pressurized air thereto. The transfer valve assembly is arranged to actuate the alarm mechanism when the pressure of air entering the reducer through the inlet drops to a predetermined trigger level. The predetermined trigger level is automatically selected based on a rated capacity of a pressure vessel to which the inlet is connected through a cylinder valve.Type: GrantFiled: April 29, 2008Date of Patent: January 11, 2011Assignee: STI Licensing Corp.Inventor: Ronald B. Mele

Patent number: 7866338Abstract: A breathing air tank and valve assembly is provided for use in a self-contained breathing apparatus. The breathing air tank and valve assembly includes a pressure vessel and a cylinder valve for connection to the pressure vessel. The cylinder valve includes a valve body having an interior, and a first fitting adapted to connect the valve body directly to the pressure vessel, thereby creating a fluid connection to the interior of the valve body. The cylinder valve includes a second fitting that is an outlet adapted to connect the valve body to a pressure reducer assembly, and a third fitting that is an inlet having a check valve. The third fitting is adapted to connect the valve body to an external source of pressurized air and thereby provide a direct air path from the external source of pressurized air through the interior of the valve body to the pressure vessel.Type: GrantFiled: April 29, 2008Date of Patent: January 11, 2011Assignee: STI Licensing Corp.Inventor: Ronald B. Mele

Patent number: 7658190Abstract: A powered air-purifying respirator that includes an enclosure, defining a single contiguous enclosed interior, an inlet duct, including an inlet and a distribution portion, that guides ambient air to the interior of the enclosure, a plurality of filter canisters disposed within the interior of the enclosure, and a blower that forces air through the at least one inlet, into the interior of the enclosure and through the plurality of filter canisters to produce filtered air suitable for breathing. A valve controls the flow of ambient air through the inlet duct. A fluid dam, disposed in an air path between the inlet and the filter canisters prevents liquids from reaching the filter canisters. The enclosure is reinforced and is adapted to provide protection for the filter canister from flame and heat while the filter canister is in use. A recirculation valve recycles previously-filtered air back into the enclosure.Type: GrantFiled: April 6, 2005Date of Patent: February 9, 2010Assignee: STI Licensing Corp.Inventors: Jerry Allen Phifer, William Eugene Parson, Judge W. Morgan, III, Robert Daniel Williams

Patent number: 7628152Abstract: A breathing regulator having a non-linear positive pressure spring is provided for use in an air supplied respirator. The regulator includes a housing formed from a regulator body and a cover sub-assembly, a diaphragm assembly, and the non-linear spring. The spring holds the diaphragm assembly closed and resists the force applied by air pressure during exhalation by the user, but collapses once a sufficient amount of force has been applied, thereby permitting the user to exhale freely.Type: GrantFiled: April 26, 2004Date of Patent: December 8, 2009Assignee: STI Licensing Corp.Inventors: Jason M. Patterson, Samuel C. Shomstein

Patent number: 7377835Abstract: A personal multimedia communication system and network for emergency services personnel includes a plurality of personal communication systems linked together and to a base station in a network. Each personal communication system includes a PDA device mounted on a PASS control console, a video camera mounted on the PDA device, a GPS unit, a microphone, and other electronic devices. The various electronic devices are all communicatively connected to the PDA device. Data from the various devices may be collected in the PDA device and wirelessly transmitted to any other node or device in the network, including other personal communication devices. Each personal communication device may serve as a repeater, thus providing a wireless communications link between a device located out of range of the base station.Type: GrantFiled: August 7, 2007Date of Patent: May 27, 2008Assignee: STI Licensing Corp.Inventors: Craig M. Parkulo, Wesley McChord Barbee, Jerald Robert Malin, Jeffrey Lynn Landis, Matthew Shannon

Publication number: 20070151612Abstract: A quick pressure reducer and cylinder valve for use with an SCBA includes a cylinder valve that connects to a pressure vessel, a pressure reduction assembly for reducing the pressure of breathing air provided by the pressure vessel, a probe, and an inlet/latch assembly. The probe includes a notch and a threadless probe tip, and the inlet/latch includes a corresponding receptacle and one or more latches adapted to fit into the notch to retain the probe in the receptacle. A pushbutton switch in the receptacle is triggered by insertion of the probe tip therein, thereby providing an electrical signal. Probes of different lengths may be used to correspond to different pressure capacities, and the inlet/latch assembly may be arranged either to permit the insertion of only probe size or may be arranged to accept both sizes but to function differently based on the size of the probe. The latches are inoperable except at or below a nominal pressure.Type: ApplicationFiled: March 6, 2007Publication date: July 5, 2007Applicant: STI Licensing Corp.Inventor: Ronald Mele
