| 41 | Spring contact, inertia switch, and method of manufacturing an inertia switch | US14461859 | 2014-08-18 | US09378909B2 | 2016-06-28 | David Gass; Brent Salamone; Corey C. Jordan |
| 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. | ||||||

| A method for initiating a thermal battery including: releasing an engagement between an element and a striker mass upon an acceleration time and magnitude greater than a first threshold; and moving at least one member into a path of the element to prevent the element from releasing the striker mass only where the acceleration time and magnitude is greater than a second threshold, the second threshold being greater than the first threshold. | ||||||

| 45 | Automotive acceleration alarm to inform the driver of when to limit excessive acceleration to decrease gasoline consumption | US12473421 | 2009-05-28 | US20090294261A1 | 2009-12-03 | Peter J. Pociejewski |
| The present invention provides an alarm for the automobile driver when increased acceleration occurs. A roller ball tilt switch is rotated on a base level with the ground. The roller ball inside the tilt switch rolls back during acceleration. The L.E.D. light is illuminated due to the roller ball tilt switch completing a closed circuit. | ||||||
| 46 | Micromachined shock sensor | US09873791 | 2001-06-04 | US06619123B2 | 2003-09-16 | Yogesh B. Gianchandani; Shamus P. McNamara |
| A micromachined shock sensor has a substrate with a surface on which are formed an array of acceleration sensing units. Each sensing unit has a mount fixed to the substrate, a cantilever beam extending from the mount, and a proof mass fixed to the cantilever beam and supported above the substrate to permit translation of the proof mass and bending of the cantilever beam in a plane parallel to the substrate surface. Sensing electrodes are formed on the substrate on opposite sides of the proof mass such that displacement of the proof mass in response to acceleration brings the proof mass into contact with one or the other of the electrodes at a sufficient acceleration level, effectively closing a switch and providing an electrical output signal that can be detected. The multiple acceleration sensing units are formed to make contact at different levels of acceleration, allowing the shock sensor to allow measurements over a range of accelerations. A test electrode may be formed adjacent to the proof mass to allow the proof mass to be electrostatically drawn toward and into contact with one of the sensing electrodes to allow testing of the level of acceleration required to make contact in a particular acceleration sensing unit. | ||||||
| 47 | Impact sensor | US427087 | 1989-10-23 | US5028750A | 1991-07-02 | Hans Spies; Alfons Woehrl; Horst Laucht |
| A magnetic impact sensor for motor vehicles with a safety system such as an airbag or belt tensioner for an occupant restraint system, has a circuit breaker arranged in an electrical trigger circuit of the safety system for inflating the airbag or tightening the belt by closing the trigger circuit in response to an acceleration or deceleration effective beyond a prescribed time duration. For this purpose a magnet in combination with specially shaped pole pieces forms two magnetic circuits the magnetic conductances of which are influenced by the position of a ferromagnetic ball that moves in response to an impact relative to the pole pieces to thereby open or close the circuit breaker. Normally, in the absence of an impact the ball is in a first position that keeps the circuit breaker open. When an impact occurs the ball moves into a second position to close the circuit breaker and thus the trigger circuit. | ||||||
| 48 | Mechanical unguided ballistic missile near surface fuzing switches | US522318 | 1983-08-11 | US4675480A | 1987-06-23 | W. Dale Jones |
| A shock-damped and electronically passive mechanical switch system is precisely responsive to unguided ballistic missile peak reentry drag levels and respective near surface drag levels. The system includes a single cylindrical case containing a first and a second switching piston independently biased by respective springs, and a third switching piston housed in the second piston and controlled by metering fluid. The third (arming) piston begins displacing upon sensing a calibrated low threshold missile reentry drag value and shortly thereafter opens a port which enables the first and second pistons to begin displacing in response to the missile's drag, these two pistons coming to rest upon sensing the missile's peak drag. The second (programming) piston retains its peak drag sensing position to thus program the near surface drag value as the first piston retracts in response to the missile's reducing post peak drag. The third piston reaches its arming position between the missile's peak drag and near surface drag experiences. The first (near surface drag switching) piston closes the warhead fuzing circuit as it senses the near surface drag value programmed by the second piston. | ||||||
| 49 | Acceleration switch | US132205 | 1980-03-20 | US4284862A | 1981-08-18 | David L. Overman; Robert N. Johnson |
| An acceleration actuated switch is disclosed which is capable of distinguishing between random and brief acceleration forces on the one hand and sustained acceleration forces on the other hand. The device comprises a stationary electrical contact and a movable contact held in position by biasing means. Sustained acceleration forces in a particular direction will drive the movable contact along a fixed path to a position whereat the biasing means may bring the movable contact into proximity with the stationary contact thereby closing the switch. If the acceleration force is not in the proper direction or is not applied to the switch for a sufficient length of time, the biasing means will return the movable contact to its original position thereby maintaining the switch in an open condition. | ||||||
