Title (EN) FIRE PULSE WIDTH ADJUSTMENT
(FR) RÉGLAGE DE LARGEUR D'IMPULSION D’AMORÇAGE
Abstract:
(EN) First electronics may determine a count of bubble jet resistors to be fired by a fire pulse group. A fire pulse generator may generate a fire pulse train for bubble jet resistors, the fire pulse train comprising a precursor pulse and a firing pulse separated by a dead time. Second electronics may adjust a width of the fire pulse for the bubble jet resistors of the fire pulse group by maintaining a first edge of the fire pulse relative to the precursor pulse and adjusting a second edge of the fire pulse relative to the precursor pulse based upon the determined count for the fire pulse group.
(FR) L'invention concerne un premier élément électronique qui peut déterminer un nombre total de résistances à jet de bulles devant être amorcées par un groupe d'impulsions d'amorçage. Un générateur d'impulsion d'amorçage peut générer un train d'impulsions d'amorçage pour des résistances à jet de bulles, le train d'impulsions d'amorçage comprenant une impulsion de précurseur et une impulsion d'amorçage séparées par un temps mort. Un second élément électronique peut régler une largeur de l'impulsion d'amorçage pour les résistances à jet de bulles du groupe d'impulsions d'amorçage en maintenant un premier bord de l'impulsion d'amorçage par rapport à l'impulsion de précurseur, et en réglant un second bord de l'impulsion d'amorçage par rapport à l'impulsion de précurseur sur la base du nombre total déterminé pour le groupe d'impulsions d'amorçage.
