| 223 | Tilt sensor | US09974976 | 2001-10-11 | US20020166756A1 | 2002-11-14 | Mitchell Lee Thompson |
| A tilt switch generates a signal as a function of orientation relative to a force, especially to detect tilting relative to vertical under the influence of gravity. A movable mass is mounted for displacement along a path between preloaded and unloaded positions. In the example of gravity tilt detection, a free-falling weight or an overbalanced inverted pendulum toggles by a mass falling back and forth between the preloaded and unloaded states. The weight is unstable and accelerates from the preloaded position to an unloaded position upon application of the force. A piezoelectric element such as a resilient strip is arranged to be deflected suddenly by the movable mass, and generates an electrical signal. The piezoelectric element can be mounted to obstruct the path of the mass. In the example of a pendulum toggle, the pendulum can have two angularly spaced legs that respectively move the piezoelectric element to opposite sides of its relaxed rest position between the preloaded and unloaded positions of the mass. The switch preferably is carried on a mounting structure that constrains the path of the movable mass and defines a directional reference. | ||||||

| A tilt switch includes a pair of contact elements; and at least one ball member which rolls along a path defined between the contact elements. The contact elements are disposed facing each other with a distance therebetween, as measured at one end, which is greater than the diameter of the ball member, and as measured at the other end, which is slightly smaller than the diameter of the ball member. Tilting of the tilt switch is electrically detected through detection of whether or not the ball member is held between the contact elements. In another embodiment the tilt switch includes a housing having a hollow portion; at least one rolling member disposed to roll substantially linearly within the hollow portion; a contact mechanism accommodation portion disposed side by side with the hollow portion; a movable contact element and a stationary contact element accommodated within the contact mechanism accommodation portion and disposed facing each other, each of the movable contact element and the stationary contact element being a spring element; and a working member having a pivot formed thereon. The working member has a portion thereof projecting into the hollow portion and is rotated by movement of the rolling member to press the movable contact element into contact with the stationary contact element. | ||||||
| 227 | Flow, tactile and orientation sensors using deformable microelectrical mechanical sensors | US09207280 | 1998-12-08 | US06202495B1 | 2001-03-20 | Paul M. Zavracky; Nicol E. McGruer |
| A microelectric flow sensor including a deformable mechanical element is disclosed. The sensor includes a beam element mounted to a substrate. The beam element is anchored to the substrate on a first end, and deformed to a position normal to the surface of the substrate. An electrode is positioned on the substrate below a portion of the beam, such that when the beam is deflected, an electrical connection is established between the beam and the electrode. An alternate flow sensor includes a sensing beam surrounded by at least two cantilever beams which act as switches. The sensing beam is defined with two mechanically weak points which allow the sensing beam to be mechanically deformed to a new position approximately perpendicular to the cantilever beams and the top surface of the substrate. The substrate also includes electrodes which are positioned underneath the ends of the cantilever beams. With the sensing beam perpendicular to the surface, forces applied to the sensing beam will cause the beam to deflect. Because the cantilever beams are mechanically connected to the sensing beam the cantilever beams are bent towards a substrate upon deflection of the sensing beam. The flow sensor may be configured to function as a tilt sensor by attaching a weight proximate the end of the sensing beam. The flow sensor can be further modified to perform in harsh environments by including a diaphragm surrounding the cantilever beams and electrodes, with the sensing beam extending therethrough. | ||||||
| 228 | Modified spring switch and light module therefor | US018361 | 1998-02-04 | US6065851A | 2000-05-23 | Kwok Kwong So |
| Flashing footwear includes at least one light source located on an external surface of the footwear so as to be visible. A power source provides sufficient power to illuminate the light in response to a change in the conductive state of a spring switch. A circuit is combined with the battery and switch to form a module arranged in the heel of the footwear. The switch is comprised of an electrically conducting coil spring which is fixed at one point and is free at one end. The free end is cantilevered over a substrate and includes a non-conducting weight. An electrically conducting contact arch is positioned on the substrate beneath the spring and between the fixed point and the free end, and extends towards the coil spring. The fixed point of the spring and the contact are connected to the remainder of the lighting circuit. When a sufficient force is exerted on the spring, the spring touches the contact, thus closing the switch. | ||||||

| A tilt switch array is used to determine the orientation of an object relative to an upwards direction. The array includes at least one pair of electrodes within a housing, diametrically opposed along a measurement axis. A conductor equidistantly surrounds each electrode to form a tilt switch gap therebetween. A moveable conducting element within the housing closes the gap between one electrode and its associated conductor under certain orientation conditions of the measurement axis relative to an upwards direction. A number of pairs of electrodes may be placed within the housing, with associated measurement axes so that the orientation of any one of the measurement axes may be detected. | ||||||

| A seismosensitive element includes a housing formed from an electrically conductive material and having an inclined face formed on the bottom thereof to gradually rise concentrically outwardly substantially from a center of the inner bottom face, and a header fixed to the housing to close its open end and having through-aperture in which an electrically conductive terminal pin is fixed in an insulated relation. A contact is fixed an end of the terminal pin located inside the housing and has a plurality of feather portions disposed concentrically with the terminal pin, the feather portions having a predetermined elasticity. An inertia ball is enclosed in the housing to be located substantially at the center in the housing in a normal position of the element in a stationary state. The inertia ball rolls when subjected to oscillation, so that the inertia ball slides on the feather portions of the contact except for distal ends of the feather portions such that the inertia ball electrically conducts between the contact and the housing and such that the feather portions are elastically deformed, thereby receiving a force causing the same to be pushed against the bottom of the housing. An acceleration responsive switch includes a receptacle including a housing having a conical face, an inertial ball in the receptacle, and an oscillation damping liquid in the receptacle. The oscillation damping liquid has a viscosity such that the inertial ball terminates rotation when it is subjected to an external oscillation to be rotated. | ||||||

| A gravity-actuated switch having a switch module with a switch housing and a lid. An electrically conductive pendulum is pivotally secured to the lid via a pivot pin so that the pendulum hangs within the housing and pivots with respect to the housing under the influence of gravity. A first electrical contact connectable to a power source abuts the pivot pin, which is electrically conductive. A second electrical contact is provided within the housing in a predetermined position such that the pendulum makes contact with it when the switch module is tilted by a predetermined amount. When the pendulum makes contact with the second electrical contact, a short circuit is provided across the pair of contacts, thus closing the switch. The switch is incorporated in a lamp assembly provided on the underside of the hood or trunk lid of an automobile to selectively provide power to a lamp so that the lamp is illuminated only when the hood or trunk lid is opened by at least a predetermined amount. A switch composed of a pivoting magnet and a magnetic switch can be used instead of the combination of the conductive pendulum and the curved electrical contact. | ||||||
| 233 | Tilt switch with increased angular range of conduction and enhanced differential characteristics | US552181 | 1995-11-02 | US5672856A | 1997-09-30 | Edgar C. Kolb; James S. Robinson |
| A tilt switch is made by attaching two electrically conductive members to a nonconducting tube and disposing a conductive sphere within the switch. The first and second electrically conductive members are provided with inner cylindrical surfaces of different diameters in order to create an asymmetry that allows the angular conducting range of the switch to be increased without increasing its differential angle at one limit of travel. The first and second electrically conductive members that are used as the end caps of the switch are provided with inner cylindrical surfaces of different diameters. When the conductive sphere is disposed within the switch, it can assume three different positions in relation to the first and second electrically conductive members. A first position is defined by the sphere being in contact with both electrically conductive members and supported by contact points of both members. The second position is defined by the sphere being in contact with a first contact point but in noncontact relation with a second contact point. The third position is defined by the sphere being in contact with the second contact point but being in noncontact relation with the first contact point. | ||||||
