A device for optically scanning and measuring an environment is provided. The device includes a movable scanner having at least one first projector for producing at least one uncoded first pattern on an object in the environment. The scanner includes at least one camera for recording images of the object provided with the pattern and a controller coupled to the first projector and the camera. The device further includes at least one second projector which projects a stationary uncoded second pattern on the object while the scanner is moved. Wherein the controller has a processor configured to determine a set of three-dimensional coordinates of points on a surface of the object from a set of images acquired by the camera based at least in part on the first pattern. The controller is further configured to register the set of images relative based in part on the stationary second pattern.

A smart grid for improving the management of a power utility grid is provided. The smart grid as presently disclosed includes using sensors in various portions of the power utility grid, using communications and computing technology, such as additional bus structures, to upgrade an electric power grid so that it can operate more efficiently and reliably and support additional services to consumers. The smart grid may include distributed intelligence in the power utility grid (separate from the control center intelligence) including devices that generate data in different sections of the grid, analyze the generated data, and automatically modify the operation of a section of the power grid.

Cloud-aware industrial devices feed robust sets of data to a cloud-based data analyzer that executes as a service in a cloud platform. In addition to industrial data generated or collected by the industrial devices, the devices can provide device profile information to the cloud-based analyzer that identifies the device and relevant configuration information. The industrial devices can also provide customer data identifying an owner of the industrial devices, contact information for the owner, active service contracts, etc. The cloud-based data analyzer leverages this information to perform a variety of custom analytics on the data and generate reports or notifications catered to the particular industrial assets' optimal performance and business goals of the owner's industrial enterprise, as well as perform real-time decision making and control.

The present invention provides a method and apparatus for integrating applets running on a client with the application logic for applications running on a server The mechanism of the present invention provides two significant advantages over the prior art: the synchronization of state, and the recognition of user actions in the browser including the invocation of the appropriate application logic in the server Instead of using the FORM element available in HTML, individual active applets are available and may be created that obtain user input (eg a checkbox, textbox, button, etc) A hidden applet called the Applet Group Controller is created which handles communication between the applets on the browser and the application logic on the server The Applet Group Controller maintains an association with each applet that maintains the keys and values of any parameters and variables for the applet In a preferred embodiment, upon the invocation of an event, the association instructs an Action Coordinator to invoke an action The Action Coordinator obtains and transmits a list of all of the keys and their values to the server The server invokes the appropriate application logic and transmits the keys and their values (as updated during the execution of the application logic) back to the Action Coordinator The Action Coordinator then pushes the updated values out to the applets (through their Associations) at which time the browser's display is updated with the new values

A portable articulated arm coordinate measuring machine for measuring the coordinates of an object in space is provided. The AACMM includes a base and an arm portion having an opposed first and second ends. The arm portion including a plurality of connected arm segments that each includes at least one position transducer for producing a position signal. An electronic circuit is provided that receives the position signal from the at least one position transducer and provides data corresponding to a position of the measurement device. A noncontact three-dimensional measuring device is coupled to the first end, the device having an electromagnetic radiation transmitter and is configured to determine a distance to an object based at least in part on the speed of light in air. A processor is configured to determine the three-dimensional coordinates of a point on the object in response to receiving the position signals and the distance to the object.

A method and circuit for precisely synchronizing clocks in separate nodes on a communication network is provided by adjusting timestamps and related data in network messages. The circuit will allow a daisy-chain connection of the nodes and will forward time synchronization frames while accounting for delays in a manner that does not use boundary clocks, but does not depart from the IEEE 1588 standard protocol. The delays will be added on the fly to synchronization packets and the IP checksum and frame CRC will be adjusted. Deterministic data delivery and redundant data paths are also provided in a full duplex Ethernet network.

Time synchronization, deterministic data delivery and redundancy for cascaded nodes on full duplex ethernet networks

One or more embodiments provide Common Industrial Protocol (CIP) based time synchronization systems and methods. The CIP Sync solution can be part of Ethernet/IP and can be based on standard UDP (User Datagram Protocol) and/or IEEE 1588 (Time Synchronization) Ethernet technology. According to an embodiment is a system that compensates for step changes in a master clock.

Step time change compensation in an industrial automation network

Systems and methods that correlate among disparate pieces of synchronized data, collected from an “internal” data stream (e.g., history data collected from an industrial unit) and an “external” data stream (e.g., traffic data on network services). A process trend component that determines/predicts an outcome of an industrial process and facilitates diagnostics/prognostics of an industrial system. Accordingly, relations among various parameters can be discovered (e.g., dynamically) and proper corrective adjustments supplied to the industrial process. Such enables a tight control and short reaction time to process parameters, and for a modification thereof.

Correlation of non-times series events in industrial systems

A coordinated system time is established for spatially separated components of an industrial control system using synchronizing messages transmitted over a communication link between those parts. Precisely coordinated actions may be obtained at separated components by the use of a time conditional command received by those components prior to a time of execution the command instructing the component to execute the command only when at execution time in the future has been reached. The coordinated system time may be used to time stamp received triggering events for use in coordinating subsequent actions based on those triggering events.

A method of precisely synchronizing clocks held in separate nodes on a communication network is provided that adjusts clock frequency based on a measure of relative clock rates and absolute clock offsets. In one embodiment, clock convergence is obtained with one synchronization session.
