| 20090277268 | MAGNETIZED PULSAR RING AND ROLLING BEARING APPARATUS WITH SENSOR HAVING THE SAME - [Means for Resolution] A magnetized body is a bonded magnet and is fixed to a support member by integral injection molding. A bend portion extending axially outwardly is formed in an outwardly-directed flange portion of the support member. A come-off preventing concave portion is constituted by the bend portion and the outwardly-directed flange portion. The magnetized body enters this concave portion. Consequently, the magnetized body is prevented from performing relative movement with respect to the support member. | 11-12-2009 |
| 20110259102 | SPEED SENSOR - A speed sensor has a static part and a dynamic part arranged concentrically inside the static part. The static part has two permanent magnets and the dynamic part has two further permanent magnets. The magnet is oriented reversely to the further magnets. The magnets are tuned to each other so that gravity on the dynamic part is counteracted by the magnetic force on the dynamic part. As a result, the weight of the dynamic part need not be carried by springs and the dynamic part can move freely so that the full stroke can be used for measuring accelerations and the natural frequency is low. The static part further includes a measuring coil for measuring the displacement of the dynamic part and for the radial positioning of the dynamic part this part is connected to the static part by means of leaf springs. | 10-27-2011 |

| 20130000406 | System and method for determining a gate position - A system and method for determining the position of a moveable barrier relative to the fully open position and fully closed position. The invention utilizes in a preferred embodiment a geo-magnetic sensor to determine the extent to which the barrier has traveled from reference position of fully open or fully closed to some intermediate point. A multi-axis sensor provides an output which changes during the barrier's excursion relative to each of the respective axes so that direction or tilt may be readily known in between the closed and open positions. Operation of the gate or barrier may be more efficiently controlled when its precise location between open and closed is known. | 01-03-2013 |
