A system identifying device for identifying an unknown system interposed between first and second input terminals. Coordinate data on a pseudo subject-plane representing a subject-plane virtually covering a plurality of subjects to be shot by the camera are stored. The transmission is specifically controlled to obtain a desired ground speed independent of the selected engine speed. When the basketball goal is assembled, a slot of the first yoke member is coupled to a coupling shaft of the second yoke member, the connecting pin is engaged to both yoke members, and the basketball goal support is coupled to the backboard by the bracing means. Energy management logic calculates and provides to the user an energy management solution, to reduce energy consumption and costs, by applying rule-based artificial intelligence to the stored energy consumption data in conjunction with information from the Internet.
