Abstract: A pressure regulator includes a cylinder and a piston contained in the cylinder. First and second O-rings are attached to the cylinder and configured to form a seal between the cylinder and an interior wall of the piston. The pressure regulator has a lubrication system that includes a lubrication reservoir between the first and second O-rings defined by an annular groove in an exterior surface of the piston and the interior wall of the cylinder, and an input port extending through the cylinder to the lubrication reservoir. The piston is configured to move along a central axis relative to the cylinder between first and second positions. The first and second O-rings are displaced from the input port during movement of the piston between the first and second positions.

Abstract: Security systems are warned of earthquakes, tornadoes, and other natural disasters. When an early warning system detects a natural disaster, the early warning system alerts a central server. The early warning system alerts the central server to the natural event and its associated geographic area. The central server may then consult a database and determine the security systems operating in a vicinity of the geographic area experiencing the natural event. The central server may thus warn the security systems of the natural event. The security systems may then implement pre-programmed procedures to protect life and property during earthquakes, tornadoes, and other natural disasters.
