Methods, medium, and machines which compress, encode, enhance, transmit, decompress and display digital video images in real time. An approach time calculator calculates an approach time at which an autonomous running apparatus and the moving person approach to each other within a predetermined distance from the moving person’s position, moving direction, and speed, and the running information. An upper wall is coupled to and extends upwardly from an upper surface of the panel defining a primary cup for receiving a beverage container. Measurements of hydrostatic pressure are converted into equivalent circulating density measurements which in turn are used in calculating the sweep efficiency. The condition of the oil is selectively monitored according to whether the marine engine is operating at a speed that is less than an engine speed threshold value, which denotes a speed of the marine engine at which the oil and the gas form an oil and aerated gas mixture. Next, each one of the two subsystems ignores signals from the other subsystem for a predetermined time period after recognition of the physical connection.
