| 20090066449 | Electromechanical Latching Relay and Method of Operating Same - A latching relay employing a movable cantilever with a first permanent magnet and a nearby second magnet is disclosed. The permanent magnet affixed to the cantilever is permanently magnetized along its long (horizontal) axis. The cantilever has a first end associated to the first pole (e.g., north pole) of the first magnet, and a second end associated to the second pole (e.g., south pole) of the first magnet. When the first end of the cantilever approaches the second magnet, the first pole of the first magnet induces a local opposite pole (e.g., south pole) in the second magnet and causes the first end of the cantilever to be attracted to the local opposite pole of the second magnet, closing an electrical conduction path (closed state). An open state on the first end of cantilever | 03-12-2009 |
| 20090261927 | Coupled Electromechanical Relay and Method of Operating Same - An electromechanical relay employing a movable first permanent magnet and a nearby third electromagnet is disclosed. The movable first magnet is permanently magnetized and has at least a first end. The third electromagnet, when energized, produces a third magnetic field which is primarily perpendicular to the magnetization direction of the first movable magnet and exerts a magnetic torque on the first magnet to force the first magnet to rotate and closes an electrical conduction path at the first end. Changing the direction of the electrical current in the third electromagnet changes the direction of the third magnetic field and thus the direction of the magnetic torque on the first magnet, and causes the first magnet to rotate in an opposite direction and opens the electrical conduction path at the first end. Multiple magnets can be stacked together to form multi-pole-multi-throw relays. Latching and non-latching types of relays can be formed by appropriately using soft and permanent magnets as various components. | 10-22-2009 |

The first magnet can comprise multiple magnetic layers to form relatively closed magnetic circuits with other magnetic components. Latching and non-latching types of relays can be formed by appropriately using soft and permanent magnets as various components. | 07-22-2010 |
