摘要： A method and apparatus for controlling an earthworking implement on an earthworking machine to preserve a crown on the surface of a road, including determining the position of the crown on the road surface, choosing a sloped grade on one side of the crown, positioning the earthworking implement on the sloped grade so that a first end of the earthworking implement is on the road surface. The processor determines a desired position of a second end of the earthworking implement so that the second end overlaps the crown and the earthworking implement does not cut the crown.

摘要： The present invention relates to an electronic shootout game and more specifically to such a game intended to be played by two contestants disposed in facing relation on a prescribed shooting field. The game accurately simulates the 19th Century gunfighting practice and is completely controlled by a programmable micro-processor which includes audio and visual display to control and track the progress of the game during play. The guns include a radio frequency transmitter and antenna system which broadcasts the firing and successful hit modes by wireless communication with the computer which provides an instantaneous readout of such game functions.

摘要： A computer-aided farming system having a first control system which receives data defining a plurality of parameters. The first control system responsively determines a plurality of nodes located at an agricultural field, and determines a condition status associated with each node. The system also has a second control system located on an agricultural machine which receives data defining the nodes and the condition status at each node. The second control system then plans a path as a function of the nodes, and determines a desired work operation relative to each node. A machine controller controls the agricultural machine to perform the desired work operation at each node.

摘要： An arc welding head suitable for robotic welding has a fiber optic bundle and remotely located laser light source which is imaged onto an end of the fiber optic bundle and optically linked to substantially a single fiber of the fiber optic bundle. The light source is then repetitively scanned across the coherent arrangement of fibers within the bundle, such that, a substantial portion of the transmitted light will be sequentially delivered to each individual fiber within a row of fibers and subsequently delivered to a workpiece. This arrangement provides a high signal to noise ratio making the laser light reflected from the workpiece easily distinguishable from the optical "noise" generated by the welding arc flash.

摘要： An apparatus and method for measuring the profile of a curvilinear surface is provided. The apparatus includes a light source for substantially uniformly delivering radiant energy along an illumination plane substantially tangent to the curvilinear surface. The delivered radiant energy is optically imaged at a first image plane. A first portion of the delivered radiant energy is blocked by an optical field stop having an accurately straight reference profile edge portion, and a second portion of the imaged radiant energy is focused on a transducer located at a second image plane. The transducer produces a coded data signal in response to the focused radiant energy. A microprocessor receives the coded data signal, determines the deviation of the profile of the curvilinear surface from the reference profile edge portion, and produces a straightness signal in response to the determined deviation. Nonuniformities of the apparatus are automatically compensated for. The apparatus is simple to operate and facilitates 100% inspection in a production environment.
