| 20100164660 | Method and apparatus for coil-less magnetoelectric magnetic flux switching for permanent magnets - Methods and apparatus that employ a coil-less magnetoelectric flux switch arrangement to repeatedly switch magnetic flux from at least one permanent magnet for the purposes of generating motive force and/or electrical energy. | 07-01-2010 |
| 20100327999 | SECURITY SWITCH ASSEMBLIES FOR SHIPPING CONTAINERS AND THE LIKE - Switch-controlled security assemblies ( | 12-30-2010 |
| 20110128102 | MAGNETIC SWITCHING DEVICE - A magnetic switching device is provided with a first switching device which is provided with a movable magnet connected to a contact bridge, and with a second switching device which is provided with a magnet connected to a movable switch element. The magnets have the same polarity on the front faces facing each other. Positioned between the magnets is a separating plate made of ferromagnetic material, which is smaller than the front faces of the magnets which face each other. | 06-02-2011 |
| 20120194307 | HIGH SECURITY SWITCH ASSEMBLY - Tamper-resistant switch assemblies ( | 08-02-2012 |
| 20120223790 | RELAY - A relay is disclosed that includes a first opening and closing part including an openable and closable first gap; a second opening and closing part including an openable and closable second gap, the second opening and closing part being placed side by side with the first opening and closing part so that the first gap and the second gap are arranged side by side; a magnetization driving part configured to cause the first opening and closing part and the second opening and closing part to simultaneously operate; and a permanent magnet configured to apply a magnetic field on the first gap of the first opening and closing part and the second gap of the second opening and closing part in the same direction. | 09-06-2012 |
| 20120242435 | Micro-magnetic proximity sensor and method of operating same - 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. | 09-27-2012 |
| 20130076466 | HOUSING FOR AN ELECTRICALLY POWERED DEVICE - There is provided a housing comprising an electrically powered device and electrical connecting means. The (electrical connecting means of the) housing fit an interface means of an electrical power supply. The housing is provided with magnetically activable switching means which in a passive isolation state are open. The magnetically activable switching means prevent an electric current from passing between the electrical connecting means and the electrically powered device. The interface means comprise magnetic activation means enable an electric current to pass between the electrical connecting means and the electrically powered device when the housing has been properly installed. | 03-28-2013 |
| 20140218142 | MAGNETIC TRIGGER MECHANISM AND ASSOCIATED CONTROL METHOD - A magnetic trigger mechanism is provided. The magnetic trigger mechanism operates in conjunction with a plurality of magnetic sensors. The magnetic trigger mechanism includes: a magnet; a body, with its one side provided with a recess and its other side located near the plurality of magnetic sensors; and a moveable section, provided in the recess in a movable manner, comprising an accommodating space for restraining the magnet therein. | 08-07-2014 |
