Abstract
The extraction problem of information about the location and shape of the cavity from a single set of the temperature and heat flux on the boundary of the conductor and finite time interval is a typical and important inverse problem. Its one space dimensional version is considered. It is shown that the enclosure method developed by the author for elliptic equations yields the extraction formula of a quantity which can be interpreted as the {\it travel time} of a {\it virtual} signal with an arbitrary fixed propagation speed that starts at the known boundary and the initial time, reflects at another unknown boundary and returns to the original boundary.
