| 335266000 | Plural coils or magnets control armature movement | 8 |
| 20090261930 | Electromagnetic actuating device capable of partially holding electrification after being actuated in parallel connection - At least two sets of driving coils of the same individual electromagnetic actuating device of the present invention in parallel connection or series and parallel connection to appear relatively lower impedance being actuated to obtain larger actuating force is further manipulated by the switching device to only partially electrified coils thus reducing current passing through driving coils, while required operating characteristics of the electromagnetic actuating device can still be satisfied by the electromagnetic effective force. | 10-22-2009 |

| 20140375402 | LINEAR SOLENOID - A linear solenoid has a moving core, a main coil, and a magnetically attractive core. The moving core is supported to be capable of sliding in an axial direction of the moving core. The main coil winds around the moving core and forms a tubular shape. The magnetically attractive core magnetically attracts the moving core based on magnetic force caused by the main coil. The linear solenoid may further have a secondary coil disposed separately from the main coil so that the secondary coil intersects with the moving core at a position corresponding to the secondary coil when the moving core moves toward the magnetically attractive core. | 12-25-2014 |
| 20150077204 | LINEAR SOLENOID - A linear solenoid includes a movable element, a first stator element, a second stator element, a third stator element, a cover and a through hole. The third stator element has an opening formed on a thrust direction side of the third stator element. The cover covers the opening of the third stator element from the thrust direction side of an axial direction. The through hole passes through the third stator element. An inside of the third stator element is in fluid communication with an outside of the third stator element through the through hole. | 03-19-2015 |

| 20100277265 | Pressure Balanced Spool Poppet Valves with Printed Actuator Coils - Pressure balanced spool poppet valves with printed actuator coils minimize valve leakage and facilitate efficient manufacturing and reliable operation. The spool poppet valves may be configured like a conventional spool valve, but further include a poppet valve at one end of the spool to proved much better sealing when the poppet valve is closed. Various features are disclosed, including pressure balancing for high pressure operation. The printed actuator coils for the spool poppet valves are formed by the interconnection of conductive coils on each of multiple layers of a multiple layer printed circuit board, which circuit board may have a hole there through for accommodation of mechanical and/or magnet requirements, and may include similar printed actuator coils for one or more additional spool poppet valves as well as electronic devices associated with the operation thereof. The spool poppet valves may be advantageously constructed without printed actuator coils, and the printed actuator coils may be advantageously used in actuators of other designs. | 11-04-2010 |

| 20080278271 | ANTENNA POLARITY ADJUSTMENT - According to the invention, a system for adjusting the polarity of an antenna is disclosed. The system may include a spherical structure, at least one arm, and a coupling apparatus. The spherical structure may be at least partially spherical in shape about a central point and may include a first plurality of magnets. The at least one arm may be in proximity to the spherical structure, may include a second plurality of magnets, and may be coupled with the antenna. The coupling apparatus may be fixedly coupled with the antenna and rotatably coupled with the at least one arm. The coupling apparatus may include a third plurality of magnets, where at least a portion of the magnets may be configured to be selectively activated to rotate the coupling apparatus relative to the at least one arm. | 11-13-2008 |
| 20100127808 | COIL CONFIGURATION HAVING A COIL BRACE OF AN ELECTROMAGNETIC DRIVE - A coil configuration having a tube-shaped coil brace of an electromagnetic drive is provided, particularly a two-stage starter solenoid switch, the coil configuration having a holding winding and a pull-in winding. The coil brace has at its one end a first delimitation and at its other end a second delimitation, between which the holding winding is situated. The first delimitation has on its side, facing away from its second delimitation, an axial recess for accommodating the pull-in winding. | 05-27-2010 |
