| 81 | Blunt Impact Indicator Methods | US14337285 | 2014-07-22 | US20160178463A1 | 2016-06-23 | Gary E. Georgeson; William Joseph Tapia |
| Systems and methods using fluid-filled hollow microspheres to assist in monitoring or indicating high-energy blunt impacts on structures such as aircraft. A multiplicity of microspheres may be adhered to or embedded in a coating applied on a surface of a substrate (e.g., a tape or an appliqué), which substrate in turn can be adhered to a surface of a structure to be monitored. The microspheres are designed to rupture at one or more specified pressure thresholds. In some embodiments, the microspheres are filled with electrically conductive fluid which, if released from ruptured microsphere, changes the electromagnetic state of the substrate. In response to the detection of a sufficiently large change in the electromagnetic state of the substrate, a blunt impact indication is generated. The impact site may then undergo non-destructive inspection. | ||||||

| An integrating impact switch that can discriminate between accelerations due to different stimuli is provided. Embodiments of the present invention actuate only in response to an acceleration whose magnitude is equal to or greater than an acceleration threshold for a predetermined continuous period of time. Embodiments of the present invention comprise an impact switch having a throw that is operatively coupled with a viscous damper that dampens motion of the throw. As a result, a stimulus that imparts an acceleration that meets or exceeds an acceleration threshold for a time period less than a predetermined time-period threshold does not actuate the switch. A stimulus that imparts an acceleration whose magnitude is equal to or greater than the acceleration threshold for a time period equal to the time-period threshold, however, does actuate the switch. | ||||||

| 88 | MOUNTED SHOCK SENSOR | US12428257 | 2009-04-22 | US20090205444A1 | 2009-08-20 | Stephen P. Zadesky; Fletcher R. Rothkopf |
| This application is directed to a shock sensor mounted in an electronic device. The shock sensor includes both active and passive shock detection methods that allow a technician to determine whether the electronic device was subjected to a shock event that exceeded an impact threshold level. The shock sensor may include shock detection contacts that form an electrical circuit that remains open in the absence of a shock event that exceeds an impact threshold level. In response to a significant shock event, a movable component or substance of the shock sensor may move from a first position to a second position, thereby closing the electrical circuit formed by the shock detection contacts. The change in circuit may be detected and used to provide active indication of whether the electronic device has been subjected to a substantial shock event. In addition, the shock sensor may be observed to passively determine whether the electronic device has been subjected to a substantial shock event. | ||||||

| 91 | Emergency-deceleration condition transducer, controlling circuit for emergency-deceleration condition signal, and emergency brake lamp | US09937750 | 2001-09-28 | US06600415B1 | 2003-07-29 | Jiekui Li |
| The invention relates to emergency-deceleration condition transducers, including an insulation house made by insulation material, which defines a closed arc hollow groove. Said arc hollow groove is filled with some mercury. Said mercury in the arc groove will be moved for front and behind along the arc surface when the traveling speed is changed during the motor vehicle travailing, so that the electrodes spaced will be turned on/turned off to produce corresponding condition signal. The invention relates still to emergency brake lamps using the emergency-deceleration condition transducers, the turning on/off of the lamps will be carried out automatically without effects by driver mistaking operating, so the accident of vehicle striking from behind can be effectively avoided. | ||||||

| 94 | Mercury inertial transducer and light-emitting indicator for motor vehicles | US220149 | 1988-07-18 | US4920330A | 1990-04-24 | Lisio Plozner |
| A mercury inertial transducer includes a casing which defines an essentially L-shaped cavity having a substantially horizontal lower arm and a substantially vertical ascending arm; a volume of mercury which, in the rest condition, occupies the lower arm and essentially does not occupy the ascending arm; an input electrode which penetrates the lower arm from the outside and is permanently immersed in the mercury, and a series of separate output electrodes which are spaced along the ascending arm and can be reached in succession by the mercury when it rises in the ascending arm due to an inertial force directed along the lower arm towards the ascending arm. The transducer may be incorporated in a unit including a support which can be fixed to a movable object, such as a motor vehicle, and on which the transducer is mounted so that the inclination of its lower arm to the horizontal and of its ascending arm to the vertical can be adjusted. The transducer may also be incorporated in a deceleration and stopping indicator including an elongate hollow body provided with means for fixing to the bodywork of a motor vehicle and carrying an array of electrical light units spaced along its length. These light units are aligned transverse the vehicle and face rearwardly with respect to the direction of travel. The inertial transducer is mounted in the hollow body and its output electrodes are each connected to at least one of the light units. | ||||||
| 95 | Switching arrangement for a rotating toothbrush | US551821 | 1983-11-10 | US4544816A | 1985-10-01 | Dieter Benz |
| A switching arrangement for a rotating toothbrush which includes a rectangular casing accommodating the electric motor has a gravity switch provided in the housing and a switch actuated manually and provided externally on the housing. As a mercury gravity switch, a sensor is used, which consists of a tube closed at each end thereof and provided with a respective bottom portion at each end. Through each of the bottom portions at a lateral location, a conductor wire projects wherein through one of the bottom portions a further conductor wire projects whose forward portion within the tube is arranged at a distance to the wall of the tube and extends parallel to the conductor wires and leads almost to the end of the other bottom portion. | ||||||
| 96 | Impact switch | US527289 | 1983-08-29 | US4493956A | 1985-01-15 | Richard E. Yeoman |
| A resettable impact switch is disclosed having a non-conductive body with a cavity therein. A pair of terminals extend from opposite sides of the body and have their reverse ends extending into the cavity. A pool of mercury is disposed in the cavity to electrically connect both terminals under normal operation. The pool of mercury is held in a contact-making position within the cavity by a plurality of concentrically disposed tubular members. Longitudinal, relative movement of the tubular members allows openings in their walls to be covered or uncovered to selectively position the mercury, thereby enabling opening or closing a circuit between the terminals. One cylindrical member is carried by a post member which is adjustable within the body. The post member also carries a second contact for making or breaking electrical contact between the terminals. | ||||||
| 97 | Force-responsive device | US965784 | 1978-12-01 | US4312227A | 1982-01-26 | Karlis V. Ozols |

| 98 | Snap action tilt actuated mercury switch | US15414 | 1979-02-26 | US4201900A | 1980-05-06 | George B. Marchev |
| A mercury tilt switch is provided with electrodes which during operation are oriented in a vertical plane projecting through an end wall of an elongated insulating envelope. The lower electrode is longer than the other and terminated with a blunt end of area of such size and shape as to provide resistance to the surrounding movement of the mercury pool past the end and the subsequently reduced steps of the electrode. When the switch is tilted to close the contacts, the blunt end opposes the mercury pool until the switch is sufficiently tilted that the weight component of the mercury in direction opposed to the blunt end is sufficient to overcome surface tension of the mercury pool, at which point the mercury pool will flow down along the stepped electrode and into contact with the other electrode closing the switch. | ||||||
