Abstract: A route evaluation system includes a processor, a computer readable memory and a database that stores roadway data pertaining to a route. A first routine is arranged to obtain selected roadway data from the database. A second routine is arranged to determine a route from an origin to a destination based at least in part on the roadway data. A third routine is arranged to compute a set of navigation parameters for the route. A fourth routine is arranged to compare the set of navigation parameters to at least one vehicle maneuverability parameter of a vehicle.

Abstract: Methods and systems for determining a safest transportation route include determining a risk value for each of a set of candidate routes between an origin and a destination based on one or more safety factors or criteria, and comparing the risk values to determine the safest route. The risk values may be based upon default or selected safety factors, and may correspond to a normalized cost per unit distance. Safety factors may be derived from map data, obtained from user input and/or derived from other statistical data. User preferences and priorities may be included in the process for determining a safest route. Determined safest routes may be displayed, and may indicate especially risky portions of the determined safest route.

Abstract: A radiation therapy device and a method of changing the spatial dose distribution surrounding a focus are disclosed. A subset of radioactive sources in a source carrier arrangement is displaceable relatively to collimator passage inlets, while the rest of the sources are fixed relatively to said collimator passage inlets.

Abstract: A radiation therapy device and a method of changing the spatial dose distribution surrounding a focus are disclosed. At least a subset of the radioactive sources in a source carrier is linearly displaceable relatively to at least a subset of collimator passage inlets, or vice versa.

Abstract: Disclosed is a coupling device having two coupling parts and clamping means for releasably axially clamping both coupling parts. A plurality of circumferentially spaced non parallel grooves are cut into the surface of one of both coupling parts for having a reference in a plane perpendicular to the clamping direction. Pins project from the surface of the other coupling part each pin having two opposing parallel lateral surfaces for obtaining alignment of the grooves with the pins upon clamping. At least one of the lateral surfaces of each pin forms an angle with the associated flank of each groove upon axial alignment of the coupling parts. For improving the repeated precision of the positioning of one of the coupling parts relative to the other coupling part even upon high stress on one of the coupling parts in circumferential direction a clamping plate is provided between the lateral surface and the associated flank which is axially elastic and is mounted to one of the coupling parts.

Abstract: An essentially C-shaped tool holder (10), preferably having a long inner edge, which holder at its free shank ends can carry a tool such as a riveting, glueing or welding unit. The holder (10) comprises a truss or frame work which includes an outer and an inner C-shaped frame (11, 23) and a plurality of slewing brackets (27-32) connected to the C-shaped frames. The frames (11, 23) and the slewing brackets (27-32) are arranged to form a number of connected triangular sections, defined by connection points 18-22, 37) which are designed as intersections or joints. The outer C-shaped frame (11) is arranged to support only thrust forces; the inner frame (23) is arranged to support thrust and tensile forces, and the slewing brackets (27-32) are arranged substantially to support tensile forces.
