Abstract: A method and system. A common route is designated as a traveled route of a mobile device for a series of consecutive movements of the mobile device in a mobile network along a path of locations from an origin location of the path at an earliest activity of two or more activities of the mobile device to a destination location of the path at a latest activity of the two or more activities. A ratio is computed as a ratio of (i) a sum of a coverage area of a start cell in which one activity of the mobile device was initiated and a coverage area of an end cell in which the one activity of the mobile device was terminated to (ii) a distance between a centroid of the start cell and a centroid of the end cell such that the distance has a positive value. A confidence value as a function of the computed ratio is determined.

Abstract: A method and system for determining a traveled route of a mobile device in a mobile network. A determination is made of a series of consecutive movements of the mobile device along a path of locations from an origin location of the path at an earliest activity of a plurality of activities of the mobile device to a destination location of the path at a latest activity of the plurality of activities. Historical sets of routes of the mobile device are accessed from storage. At least one common route is ascertained from the set of routes, wherein the locations in each common route include all of the locations on the path. A common route of the at least one common route is designated as the traveled route of the mobile device.

Abstract: A method and system for determining a traveled route of a mobile device in a mobile network. Analysis of a network usage record identifies activities and associated activity information of the mobile device. A series of consecutive movements of the mobile device along a path of locations is determined from the activity information. Historical sets of routes of the mobile device are accessed. Each route is a set of locations from an origin location to a destination location of the route. At least one common route is ascertained from the set of routes. The locations in each common route include all of the locations on the path. The origin location and destination location of each common route is the origin location and destination location of the path, respectively. A common route of the at least one common route is designated as the traveled route of the mobile device.

Abstract: An ion implanter for low energy ion implantation includes an ion beam generator, a older for supporting a workpiece, such as a semiconductor wafer, and a voltage source electrically connected to the workpiece. The ion beam generator includes an ion source for generating ions and an extraction electrode having an extraction voltage applied thereto for accelerating the ions to form an ion beam. The voltage source applies to the workpiece a bias voltage that is of opposite polarity and smaller magnitude than the extraction voltage. The ions in the ion beam are implanted in the workpiece with an energy that is a function of the difference between the extraction voltage and the bias voltage.
