Patent number: 8279029Abstract: A weatherproof switch for use with an information/instrument cluster including a button having a body located adjacent to the information/instrument cluster, the body having a first end and a second end; a magnet substantially disposed within the second end of the body; a sensor located a distance from the magnet to produce a magnetic field of a first strength; and a circuit connecting the sensor to a function of the information/instrument cluster for controlling the function when the first end of the button is operated to increase and decrease the distance between the magnet and the sensor such as to produce magnetic field of a second strength.Type: GrantFiled: July 10, 2008Date of Patent: October 2, 2012Assignee: Flextronics Automotive, Inc.Inventors: Przemyslaw Chamuczynski, Allan Chun

Publication number: 20120242435Abstract: A micro-machined magnetic relay has a moveable cantilever comprising a soft magnetic material and having a first end and a second end. The cantilever has a rotational axis which is a flexure supported by a substrate. The cantilever has a first state and a second state. A first permanent magnet is disposed near the first end of the cantilever to force the cantilever in the first state. A second movable magnet causes changes of magnetic forces and torques on the cantilever. Therefore, the direction of a sum of torque on the cantilever is reversed. As a result, the cantilever flips from the first state to the second state. The relay can be used as a proximity sensor to detect the motion of an object associated with the second movable magnet.Type: ApplicationFiled: April 11, 2012Publication date: September 27, 2012Inventors: Meichun Ruan, Qunying Wei

Patent number: 8263884Abstract: A tilt switch activated light apparatus suitable for use in connection with an egress of a vehicle, the apparatus including a magnet disposed within a cavity of a housing, where the cavity is shaped so that in the event of excessive roll or pitch of the vehicle, the magnet moves to a location adjacent a switch connecting a power source to a light source, causing the switch to close and so activating the light source. An external body, either ferromagnetic or magnetic, and external to the housing and removable therefrom, may be used to hold the magnet inside the cavity in a neutral position, away from the switch, during shipping.Type: GrantFiled: December 8, 2010Date of Patent: September 11, 2012Assignee: Ibis Tek, LLCInventors: Michael E. Salmon, Joseph D. Polk, Paul W. Hunkele

Patent number: 8264308Abstract: A magnet is affixed to a shaft or other pivoting or rotating member of a switch mechanism, on the axis of rotation. The radial position of the resulting magnetic field is monitored. A change in the magnetic field radial position, optionally in excess of a threshold, indicates the onset of switch actuation, prior to operative actuation of the switch mechanism. The radial position of the magnetic field is sensed by a magnetic rotary encoder. The detection of switch actuation onset may be used to remove current from a circuit prior to operative switch actuation. Because the magnet is rigidly affixed to the shaft, there is no lost motion. Because the shaft position and encoder are magnetically coupled, the detection mechanism contains no moving parts and no mechanical linkage or coupling, and its performance does not degrade due to shock, thermal effects, vibration, or wear.Type: GrantFiled: September 4, 2008Date of Patent: September 11, 2012Assignee: Shallco, Inc.Inventor: Roderick M.

Patent number: 8242867Abstract: An embodiment is a magnetic switch assembly generally comprising a switch base coupled to a switch housing. The switch base and switch housing may be coupled to, for example, a door frame or other substantially fixed location. Adjacent the switch base and switch housing may be an actuating magnet base including a plurality of actuating magnets. The proximity to or distance from the actuating magnets in the actuating magnet base may actuate magnets within the switch housing to open and/or close a circuit and/or otherwise generate a signal that may be communicated by an interface cable to, for example, a security system. The magnetic switch assembly of an embodiment may include one or more features that impede and/or substantially prevent tampering to defeat the magnetic switch assembly.Type: GrantFiled: March 29, 2010Date of Patent: August 14, 2012Assignee: Royne Industries, LLCInventor: Warren Greenway

Publication number: 20120194307Abstract: Tamper-resistant switch assemblies (26, 162) are provided including a first movement-sensing switch (28) and a second tamper-sensing switch assembly (30), the latter including a switchable component (32) and an actuating component (34). Preferably, the switch (28) and switch assembly (30) are housed within an encapsulated switch module (70, 114, 164), with the actuating component (34, 118, 138, 166) positioned above or to the side of the module (70, 114, 164). Mounting structure (36) serves to support the module (70, 114, 164) within a mounting opening (90, 112, 148) and is operable to prevent removal of the switchable component (32) and actuating component (34, 118, 138, 166) without significant relative shifting movement between the switchable component (32) and actuating component (34, 118, 138, 166). Any attempted tampering results in such relative shifting movement, thereby triggering an alarm.Type: ApplicationFiled: February 2, 2011Publication date: August 2, 2012Applicant: MAGNASPHERE CORPORATIONInventors: Randall Woods, Joseph Hedeen
