Power conversion systems and methods are provided for ride through of abnormal grid conditions or disturbances, in which a system rectifier is operated in a first mode to regulate a DC voltage of an intermediate DC circuit, an inverter is operated in the first mode to convert DC power from the intermediate DC circuit to provide AC output power to drive a load. In response to detecting an abnormal grid condition, the system changes to a second mode in which the rectifier is turned off and the inverter regulates the DC voltage of the intermediate DC circuit using power from the load.

An industrial visualization system generates and delivers virtual reality (VR) and augmented reality (AR) presentations of industrial facilities to wearable appliances to facilitate remote or enhanced interaction with automation systems within the facility. VR presentations can comprise three-dimensional (3D) holographic views of a plant facility or a location within a plant facility. The system can selectively render a scaled down view that renders the facility as a 3D scale model, or as a first-person view that renders the facility as a full-scale rendition that simulates the user's presence on the plant floor. Camera icons rendered in the VR presentation can be selected to switch to a live video stream generated by 360-degree cameras within the plant. The system can also render workflow presentations that guide users through the process of correcting detected maintenance issues.

Techniques to facilitate protecting control data used in an industrial automation environment are disclosed herein. In at least one implementation, an encryption key pair is generated for an industrial controller, wherein the encryption key pair comprises a public key and a private key. The private key is stored within a secure storage system of the industrial controller. Controller program content is then encrypted using the public key to generate encrypted controller content. The encrypted controller content is then provided to the industrial controller, and the industrial controller is configured to decrypt the encrypted controller content using the private key and execute the controller program content.

A three-dimensional (3D) sensor device achieves high intrusion detection probability while keeping the probability of a false intrusion detection low by capturing a set of multiple spatial or temporal samples of a measured parameter for an object detected in the sensor's field of view. When an object is detected in the field of view, the TOF sensor device defines a window of N pixels comprising a subset of the pixels corresponding to the object, and obtains N distance measurements corresponding to the N pixels of the window. If the number of the N distance values that are less than a defined threshold distance is equal to or greater than a selected threshold value M (an integer less than N), the TOF sensor device determines that the object is intruding within a protective field and generates a suitable output.

Systems, methods, and apparatuses are provided for a "path affinity" engine that may work in the background to discover route information needed to connect industrial control components to control level data using "tag names." Connections may be established dynamically through the path affinity engine, thereby simplifying the commissioning process and allowing connections to be made on an as needed basis. Accordingly, discovery of tag locations at runtime may be permitted, and implementing hardware changes in industrial control environments may be greatly simplified.

Techniques to facilitate protecting control programs used in an industrial automation environment are disclosed herein. In at least one implementation, control system content provided by a primary entity is received along with a primary security authority provided by the primary entity, wherein the primary security authority defines primary usage rights for the control system content granted to a secondary entity. A secondary security authority provided by the secondary entity is received, wherein the secondary security authority defines secondary usage rights for the control system content that further restrict the primary usage rights. A request is received from a user associated with the secondary entity to perform an action associated with the control system content, and the request is processed with the secondary security authority to determine if the user is authorized to perform the action associated with the control system content based on the secondary usage rights.

A system includes a heat sink, a semiconductor device, and a layer of thermal interface material (TIM) disposed between the heat sink and the semiconductor device. The TIM may facilitate dissipation of heat generated by the semiconductor device via the heat sink. The system also includes a fastener system that couples the semiconductor device to the heat sink about the layer of TIM. The system also includes one or more washers of the fastener system that maintain a coupling force between the semiconductor device and the heat sink after the TIM flows.

For machine procedure simulation , a synchronization module stores a plurality of equipment procedures in a procedure database. Each equipment procedure corresponds to an equipment instance of a plurality of equipment instances and each equipment instance corresponds to an equipment reference code. The synchronization module further synchronizes the plurality of equipment procedures to a mobile device. A retrieval module receives a first equipment reference code at the mobile device and retrieves a first equipment procedure indexed to the first equipment reference code. The first equipment procedure includes a machine simulation for the first equipment instance. A training module receives a procedure step directed to the machine simulation. In addition, the training module displays an operator simulation interacting with the machine simulation in response to the procedure step.
