A control device for power saving for personal computers, printers, etc. which generates a suspension signal or a power-off signal to perform power saving by detecting input horizontal and vertical sync signals. The suspension signal provides a suspension mode for a minimum basic operation of the computer or printer, while the power-off signal provides a system power-off mode. The control device is designed as a digital circuit comprising latches, counters, monostable multivibrators, and other logical elements. Integration of the circuit is possible as well as its transient response characteristic is improved.

Dispositif de régulation permettant d'économiser de l'énergie pour ordinateurs personnels, imprimantes, etc. Le dispositif génère un signal de mise en veilleuse ou un signal de mise hors tension en vue d'économiser de l'énergie en détectant un signal d'entrée de synchronisation horizontal et un signal d'entrée de synchronisation vertical. Le signal de mise en veilleuse enclenche un mode de fonctionnement en veilleuse qui assure le fonctionnement de base minimum de l'ordinateur ou de l'imprimante, tandis que le signal de mise hors tension met le système hors tension. Le dispositif de régulation est conçu en tant que circuit numérique comprenant des verrous, des compteurs, des multivibrateurs monostables et d'autres éléments logiques. Le circuit peut être intégré, et ses caractéristiques de réponse transitoire peuvent être améliorées.
