Message synthetizer

Claim 1

Message synthetizer device for providing a message consisting of a number of separate digits, terms etc. indicating aspects and features of a sensed quantity condition in response to an interrogation signal, said device comprising: an interrogation detecting device connected to a communication circuit; a sensor means for sensing the value of said condition; an A-D-converter connected to said sensor means having an output for delivering the digital value of said sensed quantity; recorder means with a plurality of endless tracks with recordings of information including said digits, terms etc.; a plurality of read-out devices, one for each of said tracks; an output circuit individually connected from each read-out and each including a controlled switch device connected to a common signal line adapted to be connected to said communication circuit; means for continuously moving said endless tracks past said read-out devices; controlled memory devices connected to receive and, upon detection of an interrogation signal, to store said digital value from the A-D-converter and having controlled output circuits responsive to programmed signal sequence connected to selected ones of said controlled switch device for predeterming the path of control signals to selected controlled switch devices for connection of appropriate digit track read-out devices, one at a time, for read-out and transmission of the corresponding track recordings to said common signal line; a program device having output control connections to the controlled counter output circuits and selected ones of said controlled switch devices for controlling delivery of recorded track information in a predetermined sequence to said common output signal line; means connected to and initiated by said interrogation device for energizing the components of said synthetizer device providing a store command signal to said memory devices and starting said program device; and logic circuit means, connected to and controlled by said program device and having output control connections to said program devices and to said means for energizing said synthetizer components, for enabling at least one repeat transmission of the same synthetized message by said program device and then terminating transmission.
