Patent EP-0204773-A4 (EP)
Inventor: WILLS LESLIE JAMES
IPC: B41J2/17
Filed: 1985-12-05
Abstract: La production de gouttelettes uniformes (5) dans des imprimantes à jet d'encre est obtenue en introduisant une variscosité périodique dans le jet de liquide (3) qui sort de chaque ajutage (2) de l'imprimante. Une impression efficace par le moyen de ces gouttelettes (5) necéssite un synchronisme exact entre le moment où les gouttelettes se séparent du jet de liquide et le moment où une charge est appliquée aux gouttelettes par une électrode de charge (4). Afin d'effectuer des compensations qui maintiennent l'exactitude de ce synchronisme en dépit de variations des propriétés du liquide d'impression, les gouttelettes d'un jet d'impression (jet de contrôle) sont contrôlées. Chaque fois que l'observation du jet de contrôle montre une variation du synchronisme, un signal correcteur (ADV, RTD) est généré pour induire une altération de l'application de variscosité, ou de l'application de charge, afin de compenser la déviation du synchronisme. Une construction préférée du jet de contrôle comprend un collecteur (6) pour les gouttelettes chargées qui reçoit les gouttelettes (5) du jet de contrôle et décharge périodiquement le liquide recueilli (7). Un amplificateur de lecture est sensible à la charge nette dans le collecteur (6), et le signal produit par l'amplificateur de lecture (11) est utilisé pour générer le signal correcteur.

Par conséquent, sans qu'il soit nécessaire d'ajouter des éléments de compensation de la charge électrique, on peut contenir un ensemble d'impuretés de centre de luminescence différentes tout en maintenant une propriété électriquement neutre dans la couche photoémettrice.
Patent EP-0434742-A4 (EP)
Title: Disposable sensing device for real time fluid analysis
IPC: G01N27/26
Filed: 1989-09-15
Abstract: A system comprising a disposable device and hand held reader can perform a variety of electrochemical measurements on blood or other fluids. In operation, a fluid sample is drawn into the disposable device through an orifice by capillary action. The orifice is sealed off and the disposable device is inserted into the reader. The reader which controls the test sequence and flow of fluid causes a calibrant pouch located inside the device to be pierced, releasing the calibrant fluid to flow across the sensor arrays to perform calibration. Next an air bladder located in the device is depressed, forcing the sample across the sensors where measurements are performed and read by the reader which performs the calibrations. Once the measurements are made, the device can be withdrawn from the reader and discarded.
