摘要:
This invention provides a Graphical User Interface (GUI) that operates in connection with a machine vision detector or other machine vision system, which provides a highly intuitive and industrial machine-like appearance and layout. The GUI includes a centralized image frame window surrounded by panes having buttons and specific interface components that the user employs in each step of a machine vision system set up and run procedure. One pane allows the user to view and manipulate a recorded filmstrip of image thumbnails taken in a sequence, and provides the filmstrip with specialized highlighting (colors or patterns) that indicate useful information about the underlying images. The programming of logic is performed using a programming window that includes a ladder logic arrangement.

This invention provides a Graphical User Interface (GUI) that operates in connection with a machine vision detector or other machine vision system, which provides a highly intuitive and industrial machine-like appearance and layout. The GUI includes a centralized image frame window surrounded by panes having buttons and specific interface components that the user employs in each step of a machine vision system set up and run procedure. One pane allows the user to view and manipulate a recorded filmstrip of image thumbnails taken in a sequence, and provides the filmstrip with specialized highlighting (colors or patterns) that indicate useful information about the underlying images. The system is set up and run are using a sequential series of buttons or switches that are activated by the user in turn to perform each of the steps needed to connect to a vision system, train the system to recognize or detect objects/parts, configure the logic that is used to handle recognition/detection signals, set up system outputs from the system based upon the logical results, and finally, run the programmed system in real time. The programming of logic is performed using a programming window that includes a ladder logic arrangement. A thumbnail window is provided on the programming window in which an image from a filmstrip is displayed, focusing upon the locations of the image (and underlying viewed object/part) in which the selected contact element is provided.

This invention provides a system and method for automating the setup of Locators and Detectors within an image view of an object on the HMI of a vision detector by determining detectable edges and best fitting the Locators and Detectors to a location on the object image view following the establishment of an user selected operating point on the image view, such as by clicking a GUI cursor. In this manner, the initial placement and sizing of the graphical elements for Locator and Detector ROIs are relatively optimized without excessive adjustment by the user. Locators can be selected for direction, including machine or line-movement direction, cross direction or angled direction transverse to cross direction and movement direction. Detectors can be selected based upon particular analysis tools, including brightness tools, contrast tools and trained templates. The Locators and detectors are each associated with a particular set of operating parameters, such as activation threshold, which are displayed in a control box within the GUI (and can be accessed by clicking on the specific Locator or Detector. A parameter bar can also be provided adjacent to the depiction of the Detector on the image view for easy reference. Both Locators and Detectors may be manually readjusted once automatically placed and sized by drag and drop techniques.

A machine vision image acquisition system is provided with a housing or enclosure that protects the acquisition system components from an industrial environment. The machine vision image acquisition system has a focusing mechanism that can be actuated externally to the housing. The focusing mechanism uses a gear drive to transmit externally actuated focus adjustments to the optical components of the acquisition system.

The invention provides, in some aspects, devices for image acquisition that use seals between concentrically disposed portions of an enclosure and an optics assembly in order to protect image acquisition components from the surrounding environment while providing adequate friction for both adjusting and locking focus. Such devices can include an image capture medium that is disposed within an enclosure and an optics assembly that is also disposed within that enclosure. The optics assembly, which includes at least a lens, can have a cylindrical outer diameter along at least a portion of its length that is received within the enclosure along a length that has a corresponding cylindrical inner diameter. A first seal is disposed between, and in contact with, the optics assembly and the enclosure. That seal permits rotation of the optics assembly for purposes of focusing the lens, while preventing contamination from the environment from entering into the enclosure.

Apparatus for folding blanks particularly those constructed from corrugated cardboard. As a blank advances along a paper line pathway, a first station engages the leading edges of the blank flaps and forces the flaps into an intermediate plane. A second station controls the relative velocity of the flaps along the paper line with respect to the panels to compensate for skew that can occur at other stations. A final station completes the folding operation. The second station includes driven rollers that engage opposite sides of each of the flaps. Independently controlled motors drive these rollers in response to the velocity of the blanks along a paper line pathway and any required offset for skew compensation. The controls can be remotely located from the station. Moreover, the station can accommodate blanks of different thicknesses, position the rollers at different locations on different flaps and accommodate cartons with different widths.

The present invention generally relates to a self-centering energy dissipative brace apparatus. A bracing system is often needed to stabilize, strengthen or stiffen structures such as buildings which are subjected to severe or extreme conditions. The brace apparatus may be installed in a structure to dissipate input energy and minimize residual deformations related to exceptional loading imposed on the structure by winds, earthquakes, impacts or explosions. The apparatus integrates self-centering properties and energy, dissipative capacities which help minimize structural damage.
摘要:
Apparatus and a method for folding flaps onto panels formed in folded box blanks, particularly those constructed from corrugated cardboard. As a blank advances along a paper line, a first station engages leading edges of the flaps and forces the flaps into an intermediate plane representing a partial folding operation. Then a second station controls the relative velocities of the flaps along the paper line with respect to the panels to compensate for skew that can occur in other stations. A final station completes the folding operation. The resulting fold is made about an axis, or fold line. If the flap is to be folded about a prestamped score line, the fold and score lines are coextensive. Typically the flaps are folded 180.degree. and the first station produces intermediate folds that are displaced 90.degree. from the panels.

An optical time domain reflectometer suitable for determining its front panel insertion loss comprises a four-port coupler having first and second ports connected to a light source and an optical detector, respectively, and third and fourth ports connected to a front panel connector and a reference reflector, respectively. In use, a fiber-under-test is connected to the front panel connector. The coupler splits light from the light source between the front panel connector and the reference reflector and couples light returning from the front panel connector and reflector to the detector. The optical path between the front panel connector and the coupler is longer than the optical path between the reference reflector and the coupler by such a distance that a Fresnel reflection pulse from the reference reflector, produced by a pulse emitted by the light source, will be received by the detector before a corresponding reflection pulse returned from the front panel connector. In order to ensure that the two reflection pulses can be distinguished from each other, the difference between the two optical paths is greater than a distance equal to an event dead zone for the particular width of pulse supplied by said light source. The reference reflector comprises an end portion of a length of optical fiber, preferably encapsulated with a material having a refractive index different from that of the length of optical fiber. The OTDR facilitates miniaturization because it avoids the use of an internal length of reference fiber.
