20090242362 | UNGUIDED BALLISTIC WARHEAD FUSE SWITCHING DEVICE - The invention is an acceleration switch designed to fuse switch unguided ballistic warheads at a specified elevation above land. It houses two spring controlled and inertia responsive electrically conductive pistons, one of which would electrically program the fuse switching acceleration value when advancing, upon sensing peak acceleration (as the reentering warhead experiences its peak deceleration), and the other of which would close the fuse switching circuit when, upon retracting, it senses the programmed fuse switching acceleration value. The switch also incorporates a remotely steppable bi-directional stepping motor which would be employed to regulate the inactive position of the fuse switching piston. | 10-01-2009 |
20120111703 | LOW-G MEMS ACCELERATION SWITCH - A motion-sensitive low-G MEMS acceleration switch, which is a MEMS switch that closes at low-g acceleration (e.g., sensitive to no more than 10 Gs), is proposed. Specifically, the low-G MEMS acceleration switch has a base, a sensor wafer with one or more proofmasses, an open circuit that includes two fixed electrodes, and a contact plate. During acceleration, one or more of the proofmasses move towards the base and connects the two fixed electrodes together, resulting in a closing of the circuit that detects the acceleration. Sensitivity to low-G acceleration is achieved by proper dimensioning of the proofmasses and one or more springs used to support the proofmasses in the switch. | 05-10-2012 |
20130153376 | Inertia Micro-Switch - An inertia micro-switch includes a shell, a cell unit and an actuator. The shell includes a drum placed between an upper unit and a lower unit. The cell unit is placed in the shell. The actuator includes a housing unit, a lower conductive rod, two movable elements and a hit-taking unit. The housing unit is placed in the vicinity of the cell unit in the shell. The lower conductive rod is placed in the housing unit and connected to the cell unit. The movable elements are placed in the housing unit. The hit-taking unit moves the movable elements and hence contacts the lower conductive rod when it takes a hit. | 06-20-2013 |
20130228425 | Setback and Set-Forward Activated Electrical Switches - An electrical switch including: a body; a mass element; a spring element attached at one end to the body and at another end, at least indirectly, to the mass element; and an inclined surface upon which the mass element moves from a resting position to an all-fire position. The inclined surface being inclined with respect to a firing setback acceleration. When the body experiences the firing setback acceleration, the mass element travels at least across the inclined surface against a force of the spring element to contact an electrical contact and close a circuit. | 09-05-2013 |

20160049270 | SPRING CONTACT, INERTIA SWITCH, AND METHOD OF MANUFACTURING AN INERTIA SWITCH - A spring contact, an inertia switch, and a method of manufacturing an inertia switch are provided. The spring contact includes a conductive body portion having an outer edge and an inner edge partially surrounding an open area, a split in the conductive body portion, the split extending between the outer edge and the inner edge, and a conductive contact finger extending from the inner edge into the open area. The inertia switch includes a shell; a mass movably positioned within the shell; the spring contact positioned within the mass; a biasing member positioned between the spring contact and the header; and a conductive member extending through the header. The biasing member provides a bias between the spring contact within the mass and the conductive member. The method includes at least partially closing the split in the spring contact during insertion of the spring contact within the mass. | 02-18-2016 |

20150380190 | QUAKE PLUG - An original apparatus that will react and shut off a main fluid source during a severe earthquake. A steel ball is held at an elevated position by a secured magnet within the housing. It is a preferred embodiment that all materials, for the exception of the steel ball are made of a non-magnetic substance, so that no internal parts interfere with the operation of the apparatus. In the event of a severe earthquake, the seismic vibrations will cause the steel ball to shake and break away from the magnet. Gravity will cause it to fall down. The steel ball will then fall onto the slide trigger. The weight of the steel ball and slide trigger will be pushed down completely and the bottom portion of the slide trigger shall make contact and engage a momentary switch. The momentary switch, in the engaged position will send direct current voltage to a normally open motorized ball valve and cause it to close. Preventing fluid to pass through said ball valve. The apparatus can be reset by manually pulling upward the lift handle towards the top cap. This will allow for the weight of the steel ball to be lifted off the momentary switch and get magnetically attached back to the magnet. Resulting in the momentary switch to disengage and the voltage will seize to power the normally open motorized ball valve, causing it to go back to its normally open state. Thus allowing the fluid to pass through the ball valve. This apparatus can be used repetitively. | 12-31-2015 |
