| 20100045275 | ROTARY OR LINEAR POSITION SENSOR HAVING AVARIABLE MAGNET PROFILE - The invention relates to a magnetic angular or linear sensor including at least one permanent magnet defined in a cylindrical (r, Q & z) or Cartesian (x, y & z) coordinate system and at least two magneto-sensitive elements, in which the magnet can move in relation to said two magneto-sensitive elements. The invention is characterized in that at least one dimension of the magnet varies as a non-constant function and in that the magnetization of the magnets is oriented in a single direction, i.e. x, y or z in the case of a magnet defined in a Cartesian coordinate system or r, Q or z in the case of a magnet defined in a cylindrical coordinate system. | 02-25-2010 |
| 20110043194 | VARIABLE RELUCTANCE POSITION SENSOR - A variable reluctance analog position device designed to determine the position variation of a target made from a ferromagnetic material. The device includes at least one magnet, the target and the magnet defining a gap therebetween. A magnetosensitive element detects induction variation produced in the gap by relative movement of the target relative to the magnet. The magnet is magnetized in a direction essentially perpendicular to the front surface of the magnet, which defines one edge of the gap. The magnet includes a cavity open at the front surface thereof and the magnetosensitive element is housed in the cavity. Moreover, the target is provided with a specific geometric configuration determined such that the induction variation according to the position of the target corresponds to a pre-defined function. | 02-24-2011 |

| 20090112467 | Map-centric service for social events - A map-centric service for creating, finding, and organizing social events is described. Social events may include gatherings, goods or services for sale or other types of events about which a group of people may wish to share information. The service provides a graphical indication of the location of a plurality of social events superimposed on a map, providing a geographic context to social events. The geographic context may be augmented with text graphical indications or information in other forms, further identifying characteristics of the social event. Information about social events may be made accessible to multiple users through a web service. A user may search for social events by specifying desired characteristics of the social event. The service can also generate an optimal route for user selected events. | 04-30-2009 |
