Abstract: An authentication system 1 that uses sound to transmit one-time password(s) may be equipped with portable terminal(s) 10, authentication terminal(s) 30, and authentication server(s) 50. Portable terminal 10 may be equipped with password generating unit(s) 21 which encrypt information including password generation user identifier(s) issued by authentication server(s) 50 and generate one-time password(s), encoding unit(s) 22 which encode one-time password(s) and generate baseband signal(s), carrier wave generating unit(s) 23 which generate carrier wave(s) in audible band(s), modulating unit(s) 25 which use baseband signal(s) to modulate carrier wave(s) and generate modulated signal(s), and speaker(s) 17 which transmit modulated signal(s) in the form of sound wave(s). One-time password(s) may be input as sound wave(s) from portable terminal(s) 10 to authentication terminal(s) 30.

Abstract: A plant activation tracking and display apparatus for use in a plant in which various points of plant components are represented by nodes including at least one system input node and at least one system output node, the adjacent nodes being connected to one another by means of fluid passages, with a pump unit and/or valve unit for creating a fluid flow in a specified direction being provided in the middle of each of the fluid passages in desired positions. An output device successively tracks each of the categorized fluids with a specified phase from the system input node to the system output node, and sequentially displays the array of the tracked nodes in one direction.
