Abstract: A method for replacing a controller on a process device that avoids downtime on a process line. The method may include retrieving data from a first controller on a valve assembly, the data comprising information that defines values for operating parameters on the first controller, removing the first controller from the valve assembly, coupling a second controller to the valve assembly, and storing data on the second controller, the data comprising information that defines the values for operating parameters corresponding with the first controller.

Abstract: A portable security inspection device based on millimetre wave imaging comprising a hand-held body (1), wherein the hand-held body (1) is provided with a millimetre-wave transmitting link (10) for generating a millimetre-wave transmitting signal, a millimetre-wave array antenna (11) for transmitting the millimetre-wave transmitting signal to a detected object and for receiving an echo signal reflected by the detected object, and a millimetre-wave receiving link (12) for processing the echo signal and converting the echo signal into image data of the detected object.

Abstract: A board-level assembly that is useful to expand functions of a valve positioner on a valve assembly. The board-level assembly can incorporate a main circuit board and a peripheral “smart” circuit board. The main circuit board may be configured to communicate with the smart circuit board, find a storage memory on the second circuit board, retrieve data from the storage memory, and use the data to configure functions on the first circuit board. In one implementation, the smart circuit board can release and engage the main circuit board. This configuration can allow different configurations of the smart circuit board to swap into the board-level assembly, each of the different configurations providing data the main circuit board can exploit to change the functions of the valve positioner.

Abstract: The present disclosure relates to a method and device for detecting concealed dangerous objects in microwave images. The method includes: simultaneously processes multiple adjacent microwave images, obtains edge images of a single image by using two methods for each image, obtains dangerous-object edges of the single image by edge fitting operation, obtains a rough dangerous-object contour by performing a registration operation and a second edge fitting operation on the dangerous-object edges of the multiple images, and performs a regional-binarization operation and a filtering on the rough dangerous-object contour to obtain a second dangerous-object area. The present disclosure has high detection accuracy and calculation efficiency.
