Alerting device for anticipating trend reversal in the evolution of a quantity

摘要

A device (DT) intended to warn the user (U) of a trend reversal to come in the evolution of a quantity (G) whose events comprise each at least a value V and a corresponding instant T. Its processing module (PM) 5 compares value V at an instant with a chosen value Vc, and if value V does not cross value Vc, compares value V assumed at the following instant with value Vc, if value V crosses value Vc, compares value V assumed at the following instant with a chosen value Va, and if value V does not cross value Va, compares value V assumed at the following instant with value Va, and if 10 value V crosses value Va, triggers an alert (A). The device also comprises graphical management means for the said values.
