Abstract
Abstract The invention relates to a computer and display system to be used for example in a gasoline dispenser in the same fashion as the conventional mechanical value register. The system is capable of electronically computing not only the amount of liquid dispensed based on a delivery pulse signal, but also the delivery cost dependent upon pre-selected cost per unit setting. This information, in the form of a seven segment display code, is multiplexed over a pair of conductors to one or more external displays or any device that can utilize the signal. The system, by the use of digital displays and electronic circuitry, will inherently round value amounts to the nearest correct unit. A modified form of the system can employ a redundancy circuit as a self-checking feature. Additionally, it can be used as a computer and display in any system involving quantitative measurements.
