Abstract: A locking arrangement can be used for securing electric module cards between two side walls of a housing. The locking arrangement includes two side members for fixed arrangement with the respective side walls. An opening defined between the side members accommodates electric contacts of the electric module cards. A first and a second transverse member form a frame with the side members in order to lock the electric module cards within the housing. A locking mechanism is detachably connects at least one of the transverse members to at least one of the side members by means of a snap-fit.

Abstract: The present disclosure relates to an IED configured for use as a protection relay in an electric power system. The IED comprises a plurality of cassettes connected to a backplane, with at least two cassettes mounted adjacent each other. Each of the cassettes comprises a housing profile in the form of a rectangular tube having an envelope wall of a heat conducting material, and at least one electronic card arranged in a card slot within the tube formed by the housing profile, which at least one card is electrically connected to the backplane. Adjacent cassettes are separated a distance such that air canals are formed between their respective housing profiles.

Abstract: A method, item communication arrangement and a computer program product communicate items representing process control objects to a user of a wireless terminal in a process control system. The arrangement includes an item communication control unit providing the items representing process control objects and configured to continuously determine weights of the items and visually communicate items to the user via the wireless terminal in an order defined by the weights of the items. The weight of an item is determined based on an item selection pattern of the user.

Abstract: A method, data presenting device and computer program product are provided for assisting a remote user. The data presenting device includes a communication interface, a camera having a field of view in which images are captured, a projector having a presentation area in which presentation items may be presented, and a control unit which receives field of view control commands a command to project a presentation item in the presentation area, controls the field of view of the camera and controls the projector to project the presentation item in the presentation area, wherein the control of the projection in the presentation area is made independently of the control of the field of view.

Abstract: A method, field user presenting arrangement and a computer program product for enabling an operator of a process control system to determine the location of field users in the process control system are provided. The arrangement includes a presentation control unit that obtains position data of the position of a field user, obtain the positions of objects in the process control system, compares the position of the field user with the positions of the objects, determines that the field user is in the vicinity of an object if the distance between the position of the field user and the position of the object is below a proximity threshold, and presents the field user on graphics depicting the process, where a field user deemed to be in the vicinity of an object is presented at this object in the graphics.

Abstract: A method, computer program product and video communication device are provided for transmitting video to a remote user. The video communication device includes a communication interface for providing a communication session with a device of the remote user, a camera capturing images, and a control unit configured to obtain a three-dimensional model of the location, control the camera to capture video images of the location, determine a current orientation of the video communication device, and transfer the three-dimensional model and orientation to the device of the remote user together with a video stream from the camera comprising the captured video images.
