Abstract: A physical condition change detection device for detecting a change in physical condition of a subject includes a body-surface-side biological information detection unit that is configured to detect a variation in biological information obtained from a body surface of the subject and that is to face the body surface of the subject and an outside thermal variation detection unit that faces away from the body-surface-side biological information detection unit and that is configured to detect a thermal variation in an outside area separated from the body surface of the subject. The physical condition change detection device further includes a transmit unit configured to provide control to transmit detection data of the body-surface-side biological information detection unit and the outside thermal variation detection unit to the outside at every given time.

Abstract: A method and apparatus for positively indicating the position of a land-based vehicle, a marine vessel or an aircraft, utilizing a security system provided in the secured mode of transportation monitored by a central station. Navigational information transmitted by LORAN-C transmitters or satellite transmitters are received and then retransmitted to the central station which determines the exact latitude/longitude coordinates of the secured mode of transportation. The secured mode of transportation also includes a security panel for monitoring the condition of various parameters. An interface is connected to the security panel and the navigational receiver for coordinating the transmission of information relating to the conditions monitored by the security panel as well as the information received by the navigational receiver before they are sent to a radio for transmission to the central station.
