If a defect flag stored in a CF 19 while a BIOS is being booted, an information processing device 10 boots a second program stored in an external device 31 connected to a connection section 21, and if the defect flag is not detected, the information processing device 10 confirms whether or not the first program is bootable. The invention is used to treat sore and painful nipples caused by breast feeding and to enable uninterrupted nursing. In conjunction with the train’s equipment, conventional crossing controllers are augmented with a communications capability and logic to accept commands to operate in a \u201cPrediction\u201d mode or a \u201cMotion-Sensing\u201d mode. The second microprocessor opens the lock if the transmitted communication code matches a preset communication code.
