A method of registering biomedical images to reduce imaging artifacts caused by object movement is disclosed, wherein a certain number of features or landmarks is automatically defined and tracked in a first and second image to be registered to determine the optical flow vector between the first and second image. A secure data channel is then created between the server platform and the user platform. The alert is received at a node on a network and translated into the original message. A piston center of gravity is positioned to the left side. A password dialog application can be located in the second area of the storage device.
