Abstract: A method of manufacturing a plurality of parts receives cutting instructions to produce a part based on a nominal model of the part. After cutting a given part, the method measures at least one particular feature of the given part with a coordinate measuring machine and subsequently calculates an error of the given part by determining an initial deviation between the cutting instructions and the nominal model. The cutting instructions are then adjusted based on the error to obtain updated cutting instructions, where the updated cutting instructions have a reduced deviation from the initial deviation with regard to the nominal model. The method then uses the updated cutting instructions to produce another part having a reduced error deviation from the nominal model.

Abstract: A system of train control uses a quasi-moving block methodology for controlling operation of a plurality of trains from a remote office. The office parses the route information for each train into non-overlapping movement authorities that are issued via a communications network. As each train proceeds, it communicates with the office to automatically roll up its movement authority and release the portion of the movement authority behind the train. The office then extends the movement authority of the subsequent train to reflect the released portion of the movement authority of the leading train. The track can be divided into a series of track circuits to enable detection of broken rail or unexpected occupancy. The office segment can then control operation of trains accordingly if broken rail or unexpected occupancy is detected in the train's movement authority.

Abstract: A method of providing an augmented view of a real world scenery and of an occluded subsurface infrastructure. An image is taken by a camera with an image sensor and image reference information comprising a camera position and a camera orientation. From three dimensional information of a subsurface infrastructure, a two dimensional projection on the image sensor is made by using the reference information. A projection position of an anchor element of the subsurface infrastructure being visible on the at least one image is compared with an image position of the anchor element. A difference between the image position and the projection position is compensated for matching and overlaying the two dimensional projection derived from the three dimensional information of the subsurface infrastructure with the at least one image and thereby providing an improved augmented view.
