A device for delivering fluid, such as insulin for example, to a patient. The device driver detects and monitors characteristics of the image capturing device as well as that of a host machine processing image data coming from the device. The generating unit generates first display information for generating a first display image which visually represents the structure of the computer program and second display information for generating a second display image which visually represents the structure of the operations. The container may include a tool pouch defined on four sides by the sealed region and containing a spreading tool. The fan assembly draws in air through one of the air channel or the second air channel and moves air out through the other of the air channel and the second air channel to cool down the temperature of the power adapter. The workstations then send the mesh representation of the 3D objects requested to the visualization console for display.
