This document describes word-dependent language models, as well as their creation and use. The central computer calculates from the received instant geographical locations, and preferably also any of weather, traffic flow rate, traffic roadblocks and stoppages, the traffic route being followed to the meeting location, and the actual rate of progress along the route to the meeting location\u2014the estimated time of arrival of each prospective attendee at the meeting. The control section also resets the communication suitability determination flag when a move of a terminal has been detected by a move detection section. The resulting sintered reactive material preferably has a tensile strength in excess of 1800 psi and an elongation at break in excess of 30%. The signal processing unit couples the touch voltage, the reset voltage, the average voltage, and a common voltage according to a second control signal, so as to generate a first coupling voltage and a second coupling voltage.
