Abstract

A communication system for communicating information between one or more sensors and a remote location which may be fixed or portable wherein the information received is converted to synthetic speech so as to verbally indicate or warn a person or persons at or near the receiver as to the condition sensed or a condition which is developing at a known or indicated remote location as indicated by the output of one or more sensors. The system may also contain a fixed data receiving station and one or more portable units for receiving signals from such fixed station and/or remote sensors wherein the fixed station serves not only to relay the information to the portable receivers but also to process the information it receives. In a particular form of the invention, the fixed station includes a computer or circuits which process the data or signals received from the sensor or sensors and generates synthetic speech signals which are short wave transmitted to one or more satellite or portable stations and generate synthetic speech thereat warning or indicating to a person or persons at or near the satellite receiver or receivers of the condition sensed.
