Patent number: 10352801Abstract: Intelligent temperature and pressure gauge assemblies (52) for use with vessels (24) having pressurized hazard suppression materials therein include temperature and pressure sensors (136, 138) coupled with a digital processor (72) with associated memory for storing empirical temperature and pressure data. The data includes normalized linear temperature-pressure curves consistent with static or slowly changing temperature conditions experienced by the vessels (24), as well as nonlinear temperature-pressure curves consistent with rapidly changing temperature conditions. In use, the assemblies (52) repeatedly sense temperature and pressure conditions of the hazard suppression material and compare sensed values with stored values, and generate an output in conformance with the comparison. In this fashion, the assemblies (52) compensate for rapidly changing temperatures without generating false failure signals.Type: GrantFiled: May 10, 2017Date of Patent: July 16, 2019Assignee: Fike CorporationInventors: Bradford T.

Patent number: 9784548Abstract: A vented pyrotechnic device is provided that hermetically seals the pyrotechnic material contained therein under ambient storage conditions, but vents upon exposure to elevated-temperature conditions at or below the outgassing temperature for the pyrotechnic material. The vent passage communicating the chamber containing the pyrotechnic material with the exterior of the device is initially sealed at ambient storage conditions by a temperature-sensitive material. When exposed to a predetermined temperature condition, the temperature-sensitive material undergoes a physical change unblocking the passage and permitting venting of off gases produced by the pyrotechnic material.Type: GrantFiled: May 13, 2015Date of Patent: October 10, 2017Assignee: Fike CorporationInventors: Ed Soohoo, Raivo Kull, Will Greeley
