201 | Rolamite sensor | EP90310789.4 | 1990-10-02 | EP0422819A1 | 1991-04-17 | Tyebkhan, Yosufi M. |
A rolamite sensor (10) includes a formed sheet metal base (18) attached to a metal chassis (14). One surface of the sheet metal base (18) acts as a guide surface (40) for a roller (20). A thin metal foil band (22) is wrapped around the roller (20) and has its ends welded to the base (82, 86) underneath the base (18). The roller (20) is biased into a first position and is rollable on the guide surface (40) from its first position under an applied force to cause the band (22) to engage a firing contact (24). A single pin (16) connected to the firing contact (24) extends through the chassis (14) and is electrically insulated from the chassis (14). The pin (16) and chassis (14) are connected to opposite electric potentials in the vehicle. When the band (22) engages the firing contact (24), an electrical circuit is completed through the pin (16), the firing contact (24), the band (22), the base (18), and the chassis (14) to activate a vehicle safety apparatus. The sheet metal base (18) includes a calibration (36) tab which sets the first position of the roller (20) along the guide surface (40). The tab (36) may be physically bent to select the distance through which the roller (20) needs to travel to complete the electrical circuit. |

202 | Magnetically-damped, testable accelerometer | EP89301612.1 | 1989-02-20 | EP0368434A3 | 1990-10-17 | Behr, Leonard Werner |
An acceleration sensor comprises a housing having a magnetically permeable element, such as a steel washer, secured thereto proximate with an end of a cylindrical passage formed therein; a magnetic sensing mass in the passage which is displaced in response to acceleration of the housing from an initial position within the passage proximate the steel washer to a second position within the passage when such acceleration overcomes the magnetic bias of the sensing mass towards the steel washer; a pair of electrically conductive rings encompassing the passage so as to provide magnetic damping for the sensing mass during the displacement thereof; and a pair of beam contacts projecting from the housing into the passage so as to be bridged by the sensing mass when the sensing mass is displaced to the second position within the passage. The accelerometer further comprises a pair of oppositely-wound electrical coils encompassing the passage proximate the initial position and the second position of the sensing mass therein, respectively. Upon the delivery of a direct current to the coils, the sensing mass is magnetically biased to the second position within the passage, whereby the beam contacts are bridged by the sensing mass to confirm the operability of the sensor. |

203 | Accelerometer with dualmagnet sensing mass | EP90302192.1 | 1990-03-01 | EP0386942A2 | 1990-09-12 | Behr, Leonard W.; Duda, Donald A. |
An acceleration sensor comprises a tube (14) formed of an electrically-conductive non-magnetic material; a magnetically-permeable element, such as a iron washer (32), proximate with the passage (24); and a sensing mass (34) in the passage (24) comprising a pair of permanent magnets (36) and a spacer (38) whose magnetic permeability increases with increasing temperature, with the magnets (36) being secured to the opposite sides of the spacer (38) so as to place a pair of like magnetic poles in opposition. In operation, the sensing mass (34) interacts with the iron washer (32) so as to be magnetically biased to a first position in the passage (24), while the magnetic-permeability of the spacer (38) and, hence, the magnetic flux generated by the sensing mass (34) adjusts to maintain a nearly constant threshold magnetic bias irrespective of variations in sensor temperature. The sensing mass (34) is displaced in response to acceleration of the housing (12) from its first position in the passage (24) towards a second position therein when such acceleration overcomes the threshold magnetic bias, while the tube (14) itself interacts with the sensing mass (34) to provide magnetic damping therefor. Upon reaching the second position in the tube (14), the sensing mass (34) electrically bridges a pair of contacts (60) to indicate that a threshold level of acceleration has been achieved. An electrical coil (70) is secured proximate with the iron washer (38) which, when energized, reversibly magnetizes the latter, whereby the sensing mass (34) is either repelled to the second position in the tube (14) or more strongly biased towards the first position therein. |

An acceleration sensor (10) comprises a tube (14) formed of an electrically-conductive non-magnetic material; a stop (30) defining an end of the tube which moves longitudinally thereof in response to temperature; a magnetically-permeable element, such as a iron washer (44), proximate with the end of the tube (14); and a sensing mass (46) in the tube (14) comprising a pair of permanent magnets (48) secured to the opposite sides of an iron spacer (50) so as to place a pair of like magnetic poles thereof in opposition. In operation, the sensing mass (46) interacts with the iron washer (44) so as to be magnetically biased against the stop (30), while the stop (30) moves longitudinally of the tube (14) to maintain a nearly constant threshold magnetic bias on the sensing mass (46) irrespective of variations in sensor temperature. The sensing mass (46) is displaced in response to acceleration of the housing (12) from its first position against the stop (30) towards a second position in the tube (14) when such acceleration overcomes the magnetic bias, while the tube (14) itself interacts with the sensing mass to provide magnetic damping therefor. Upon reaching the second position in the tube 14 , the sensing mass (46) bridges a pair of electrical contacts (54) with an electrically-conductive surface (56) thereof to indicate that a threshold level of acceleration has been achieved. An electrical coil (60) is secured proximate with the iron washer (44) which, when energized, reversibly magnetizes the latter, whereby the sensing mass (46) is either repelled to the second position in the tube or more strongly biased against the stop (30). |

A call point for use, for example, in fire alarm systems has a displaceable element (3) such as a sheet of plastics material which is displaceable so as to cause a switch (2) to indicate an alarm condition. A flag (7) indicates that the call point has been actuated and requires re-setting. The flag (7) is integral with the displaceable element so as to move, as the element (3) moves, from a first position where it is not seen to a second position where it is seen. This may be achieved by the flag (7) being visible in a window (6) when in the second position. The element (3) may be held by a catch (4) integral with the housing (1) of the call point when the element (3) is in the unactuated position. There may be a cam (58) on which the element (3) rests in its unactuated position, the cam being displaceable to restore the element to the unactuated position when it has moved to the actuated position. The call point may have a back plate (100) and a chassis (101) and a front cover with an electrical component (103) such as a switch for setting an address of the call point as on the front surface of the chassis. | ||||||
