摘要： A continuous liquid ejection system includes a liquid chamber in fluidic communication with a nozzle. The liquid chamber contains liquid under pressure sufficient to eject a liquid jet through the nozzle. A drop formation device is associated with the liquid jet. The drop forming device is actuatable to produce a modulation in the liquid jet to selectively cause portions of the liquid jet to break off into one or more pairs of drops traveling along a path. Each drop pair is separated on average by a drop pair period. Each drop pair includes a first drop and a second drop. The drop formation device is also actuatable to produce a modulation in the liquid jet to selectively cause portions of the liquid jet to break off into one or more third drops traveling along the path separated on average by the same drop pair period. The third drop is larger than the first drop and the second drop. A charging device includes a charge electrode associated with the liquid jet and a source of varying electrical potential between the charge electrode and the liquid jet. The source of varying electrical potential provides a waveform that includes a period that is equal to the period of formation of the drop pairs or the third drops, the drop pair period. The waveform also includes a first distinct voltage state and a second distinct voltage state. The charging device and the drop formation device are synchronized to produce a first charge to mass ratio on the first drop of the drop pair, a second charge to mass ratio on the second drop of the drop pair, and a third charge to mass ratio on the third drop. The third charge to mass ratio is substantially the same as the first charge to mass ratio. A deflection device causes the first drop of the drop pair having the first charge to mass ratio to travel along a first path, and causes the second drop of the drop pair having the second charge to mass ratio to travel along a second path, and causes the third drop having a third charge to mass ratio to travel along a third path. The third path is substantially the same as the first path.

摘要： A continuous liquid ejection system includes a liquid chamber in fluidic communication with a nozzle. The liquid chamber contains liquid under pressure sufficient to eject a liquid jet through the nozzle. A drop formation device is associated with the liquid jet and is actuatable to produce a modulation in the liquid jet that cause portions of the liquid jet to break off into a series of drop pairs traveling along a path. Each drop pair is separated in time on average by a drop pair period. Each drop pair includes a first drop and a second drop. A charging device includes a charge electrode associated with the liquid jet and a source of varying electrical potential between the charge electrode and the liquid jet. The source of varying electrical potential provides a waveform that includes a period that is equal to the drop pair period. The waveform also includes a first distinct voltage state and a second distinct voltage state. The charging device is synchronized with the drop formation device to produce a first charge state on the first drop and to produce a second charge state on the second drop. A drop velocity modulation device varies a relative velocity of a first drop and a second drop of a selected drop pair to control whether the first drop and the second drop of the selected drop pair combine with each other to form a combined drop. The combined drop has a third charge state. A deflection device causes the first drop having the first charge state to travel along a first path, causes the second drop having the second charge state to travel along a second path, and causes the combined drop having the third charge state to travel along a third path.

摘要： A projection apparatus for producing color images having reduced speckle artifacts comprising: at least three narrow band light sources having first, second and third visible wavelength bands; a digital image source providing color digital image data; at least one spatial light modulator for forming a color image using light responsive to the color digital image data; a projection display surface including a reflective layer that reflects incident illumination in the first, second, and third wavelength bands; and a fluorescent agent that absorbs a fraction of the incident light in the first visible wavelength bands and emits light in a corresponding first emissive visible wavelength band; and a projection lens that projects the color image onto the projection display surface; wherein return light from the projection display surface contains light in both the first incident visible wavelength band and the first emissive visible wavelength band, thereby reducing speckle artifacts.

摘要： Apparatus and method are disclosed in which a beam of radiant energy (16) is passed into a medium at a wavelength selected to cause a response of an analyte in the medium or of a sensor (10, 14) exposed to the medium, the sensor comprising a reagent whose optical properties change in response to the presence of the analyte in the medium. A perturbing pulse of energy (22) is passed into the medium to alter the response of the analyte or reagent to the beam of radiation; and the time rates of change in the intensity of the transmitted radiant energy are measured (18, 24, 26, 28) while the response is changing due to the influence of the perturbing pulse, after the perturbing pulse starts or ends or both, such rates of change being proportional to the concentration of the analyte in the medium. Both the beam of radiant energy and the perturbing pulse may be passed through optic fibers into the medium or sensor.

摘要： L'invention se rapporte à un capteur acoustique conçu pour servir de dispositif logique numérique (10). Dans un mode de réalisation, on prévoit un dispositif logique acoustique (10) comprenant une chambre de résonance (12), au moins un accès (16) établissant une première fréquence de résonance dans la chambre (12) lorsque l'accès (16) est fermé et établissant une seconde fréquence de résonance dans la chambre (12) lorsque l'accès (16) est ouvert, un émetteur (T) (20) communiquant avec la chambre (12) et syntonisé sur la première et/ou la seconde fréquence de résonance, ainsi qu'un récepteur (R) (22) communiquant avec la chambre (12) et réagissant aux signaux acoustiques se développant dans la chambre et fournissant une sortie logique numérique. Lorsque l'accès (16) est ouvert ou fermé et lorsque l'émetteur (20) est systonisé sur la seconde ou sur la première fréquence de résonance, respectivement, le dispositif (10) fonctionne comme inverseur. Dans un autre mode de réalisation, on prévoit un dispositif logique acoustique (50) comprenant une chambre de résonance (60), au moins deux accès (62, 64) établissant plusieurs fréquences de résonance dans la chambre (60) selon que les accès (62, 64) sont tous ouverts, tous fermés ou certains ouverts et les autres fermés, un récepteur (70) communiquant avec la chambre (60) et réagissant aux signaux acoustiques se développant dans la chambre et fournissant une sortie logique numérique, ainsi qu'un émetteur (72) communiquant avec la chambre (60) et syntonisé sur l'une des fréquences de résonance, déterminant ainsi le type de dispositif logique. Lorsque le dispositif (50) comporte deux accès (62, 64) et que l'émetteur (72) est syntonisé sur la fréquence de résonance correspondant à une position où les deux accès (62, 64) sont fermés ou les deux sont ouverts ou l'un est ouvert et l'autre fermé, le dispositif fonctionne comme porte ET ou comme porte NON-OU ou comme porte OU EXCLUSIF, respectivement. Sont également prévus des dispositifs logiques acoustiques comportant trois
