Abstract: The present invention discloses a fixed contact assembly of a circuit breaker for wiring, capable of controlling the flow of a current while being separated from a movable contact in a circuit breaker for wiring, which is installed to prevent overloading and short-circuit. According to the present invention, arc generated by an intermittent operation is guided directly by an arc chamber grid without an arc runner and the center of the fixed contact is directly assembled and fixed to the bottom surface of a main body in the simplest manner, thereby simplifying the structure of the fixed contact, so the manufacturing process and the assembling process can be reduced. Therefore, according to the resent invention, since the arc runner is not required, the manufacturing of the arc runner and welding and assembling work are not required, thereby contributing to reducing the production cost and to improving the productivity. A through hole is formed in the arc runner, and an intermediate portion of the fixed contact is firmly fixed to a main body through a fixing screw by using the through hole. Accordingly, the fixed contact is operable in a significantly stable state without fluctuating or moving even if an impact is applied due to the separation from the movable contact.

Abstract: Examples of the present invention include a method, a system, and an article for localizing a vehicle relative to an imaged surface configuration. Localizing the vehicle can include selecting a pair of features in an image acquired from a sensor supported by the vehicle having an identified pair of features corresponding to features in a reference representation of the surface configuration. A three-dimensional geoarc can be generated based on an angle of view of the sensor and the selected feature pair in the reference representation. In some examples, a selected portion of the geoarc disposed at a known distance of the vehicle far from a portion of a physical surface configuration can be determined. A location where the selected portion of geoarcs for selected feature pair overlaps can be identified. In some examples, the reference representation can be defined in a three-dimensional space of a volume element (voxel), and a voxel included in the highest number of geoarcs can be determined.
