Abstract: Object detection using a difference between image frames may include receiving a first image of a field of view, receiving a second image of the field of view, determining a difference between portions of the first image and corresponding portions of the second image, and declaring based on the difference between the portions of the first image and the corresponding portions of the second image that a specific object has been detected in the field of view.

Abstract: A client communication device, a server communication device and methods therein for clock synchronization of the client communication device to the server communication device. The server communication device and the client communication device are communicatively connectable via a communications network. The client communication device comprises a calculating circuit configured to calculate a client command timestamp, ClientCommandTimestamp, for a command communicated by the server device as ClientCommandTimestamp=ServerCommandTimestamp?(FirstClientTimestamp?FirstServerTimestamp)?(RoundTripTime/2). Further, the communication device comprises a synchronizing circuit configured to synchronize to the internal clock of the server device by means of the calculated client command timestamp, ClientCommandTimestamp.

Abstract: A fuel assembly is disclosed which comprises a fuel channel (1) with square cross-section supported by an inlet sleeve (22) having at its lower part an inlet opening for a flow of coolant flowing through the fuel assembly. The inlet sleeve (22) is made of stainless steel and is mechanically connected to a transition sleeve (21) made of thick zirconium alloy sheet, which is welded to the more thin-walled fuel channel (1).

Abstract: A boiling water reactor fuel assembly is provided with an elongated, vertical stiffening device having four stiffening wings (4) which are each attached to a wall of the fuel box. Each stiffening wing has at least one vertically directed passageway for water. The stiffening device has a cruciform cross-section and is composed of four elongated members (6, 6', 6", 6'") of L-shaped cross-sections.
