  • Patent number: 8957960
    Abstract: A machine vision system program editing environment includes near real time context generation. Rather than requiring execution of all preceding instructions of a part program in order to generate a realistic context for subsequent edits, surrogate data operations using previously saved data replace execution of certain sets of instructions. The surrogate data may be saved during the actual execution of operations that are recorded in a part program. An edit mode of execution substitutes that data as a surrogate for executing the operations that would otherwise generate that data. Significant time savings may be achieved for context generation, such that editing occurs within an operating context which may be repeatedly refreshed for accuracy in near real time. This supports convenient program modification by relatively unskilled users, using the native user interface of the machine vision system, rather than difficult to use text-based or graphical object-based editing environments.

  • Patent number: 7711441
    Abstract: Plural energy beam sources are aimed at an energy receiving device by way of feedback control signals. Each energy beam is uniquely modulated by way of amplitude, polarization and/or coning patterns to enable individual detection and control. Sensors detect individual energy beams incident to the energy receiving device and provide corresponding detection signals. Control electronics receive the detection signals and derive one or more control signals that are coupled to the plural energy sources. Aircraft and other vehicles are thus provided with electrical and/or thermal energy without the need for source-to-vehicle cabling or substantial on-board energy resources.

  • Publication number: 20100080417
    Abstract: A system and method for tracking, identifying, and labeling objects or features of interest is provided. In some embodiments, tracking is accomplished using unique signature of the feature of interest and image stabilization techniques. According to some aspects a frame of reference using predetermined markers is defined and updated based on a change in location of the markers and/or specific signature information. Individual objects or features within the frame may also be tracked and identified. Objects may be tracked by comparing two still images, determining a change in position of an object between the still images, calculating a movement vector of the object, and using the movement vector to update the location of an image device.

  • Patent number: 7684916
    Abstract: An imaging device collects color image data to facilitate distinguishing crop image data from background data. A definer defines a series of scan line segments generally perpendicular to a transverse axis of the vehicle or of the imaging device. An intensity evaluator determines scan line intensity data for each of the scan line segments. An alignment detector identifies a preferential heading of the vehicle that is generally aligned with respect to a crop feature, associated with the crop image data, based on the determined scan line intensity meeting or exceeding a maximum value or minimum threshold value. A reliability estimator estimates a reliability of the vehicle heading based on compliance with an intensity level criteria associated with one or more crop rows.

  • Publication number: 20100030347
    Abstract: Even in case that a wafer is so greatly deviated that a peripheral portion of the wafer cannot be detected, position determination of the wafer can be performed without inflicting a damage on the wafer. The wafer peripheral portion, which is a target, is detected based on output images from a plurality of imaging units disposed along a peripheral portion shape of the wafer (step S210), and a wafer position deviation correcting step (step S220) or a rough correcting step (step 230) is performed according to the number of the imaging units capable of detecting the wafer peripheral portion. In case that the wafer peripheral portion cannot be detected by all the imaging units, a wafer position adjusting step (step 240) for moving the wafer is performed in a position adjusting direction acquired by a combination of the output images by each imaging unit.

  • Patent number: 7547181
    Abstract: A substrate W rotates about the center of rotations A0 of a spin base 3, while supported by plural support pins 5 in such a manner that the substrate W can freely slide and while held owing to the force of friction which develops between the bottom surface of the substrate W and the support pins 5. After a detection sensor 74 detects, while the substrate W rotates, an edge surface position (eccentric position) of the edge surface of the substrate which is the farthest from the center of rotations A0, a press block 71 pushes this edge surface position to a preset position P1 which is away along the horizontal direction from the center of rotations A0 by a distance which is determined in accordance with the radius of the substrate W. This aligns the eccentric position to the preset position P1 and positions the center W0 of the substrate within a predetermined range from the center of rotations A0.
