摘要： A method, apparatus, and system are described herein for driving a droplet ejection device with multi-pulse waveforms. In one embodiment, a method for driving a droplet ejection device having an actuator includes applying a multi-pulse waveform with a drop-firing portion having at least one drive pulse and a non-drop-firing portion to an actuator of the droplet ejection device. The non-drop-firing portion includes a jet straightening edge having a droplet straightening function and at least one cancellation edge having an energy canceling function. The at least drive pulse causes the droplet ejection device to eject a droplet of a fluid.

摘要： Piezoelectric micromachined ultrasonic transducer (pMUT) arrays and systems comprising pMUT arrays are described. In an embodiment, coupling strength within a population of transducer elements provides degenerate mode shapes that split for wide bandwidth total response while less coupling strength between adjacent element populations provides adequately low crosstalk between the element populations. In an embodiment, differing membrane sizes within a population of transducer elements provides differing frequency response for wide bandwidth total response while layout of the differing membrane sizes between adjacent element populations provides adequately low crosstalk between the element populations. In an embodiment, close packing of membranes within a population of transducer elements provides improved efficiency for the wide bandwidth embodiments. In an embodiment, elliptical piezoelectric membranes provide multiple resonant modes for wide bandwidth total response and high efficiency while orthogonality of the semi-principal axes between adjacent element populations provides adequately low crosstalk between the element populations.

摘要： An apparatus includes an inkjet assembly having inkjet nozzles through each of which ink flows at a nominal flow rate as it is ejected from the nozzle onto a substrate. Ink is held under a nominal negative pressure associated with a characteristic of a meniscus of the ink in the nozzle when ejection of ink from the nozzle is not occurring. The apparatus includes recirculation flow paths, each flow path having a nozzle end at which it opens into one of the nozzles and another location spaced from the nozzle end that is to be subjected to a recirculation pressure lower than the nominal negative pressure so that ink is recirculated from the nozzle through the flow path at a recirculation flow rate. Each recirculation flow path has a fluidic resistance between the nozzle end and the other location such that a recirculation pressure at the nozzle end of the flow path that results from the recirculation pressure applied at the other location of the flow path is small enough so that any reduction in flow rate below the nominal flow rate when ink is being ejected is less than a threshold, or a change in the nominal negative pressure when ink is not being ejected is less than a threshold, or both.

摘要翻译：一种装置包括具有喷墨喷嘴的喷墨组件，当喷嘴喷嘴从喷嘴喷射到基板上时，墨水以标称流量流动。当没有发生喷墨时，油墨保持在与喷嘴中的墨水弯液面的特性相关联的标称负压下。该装置包括再循环流动路径，每个流动路径具有喷嘴端，在该端部处，该开口通向其中一个喷嘴，并且与喷嘴端间隔开的另一位置将被施加低于标称负压的再循环压力，使得油墨为以再循环流量从喷嘴循环通过流路。每个再循环流动路径在喷嘴端和另一个位置之间具有流体阻力，使得由在施加在流动路径的另一位置处的再循环压力导致的流动路径的喷嘴端处的再循环压力足够小，使得任何或者当墨水不被喷射时，低于标称流量的流量的降低小于阈值，或者当不喷射油墨时标称负压的变化小于阈值，或两者。

摘要： A method of determining whether a flow path is ready for ejection includes supplying liquid to the flow path, which includes a pumping chamber and a nozzle, after supplying fluid to the flow path, applying energy to an actuator adjacent to the pumping chamber, measuring an electrical characteristic of the actuator to obtain a measured value, and comparing the measured value to a threshold value to determine if the flow path is ready for ejection.

摘要： An electronic architecture for an imaging data path allows for printing on objects that are unevenly spaced. The architecture uses a rolling image buffer into which images are copied. A hardware trigger can optionally be used in conjunction with the rolling image buffer to prevent any printing mismatches that could otherwise be caused by a software delay. The trigger relates the physical location of the object to a virtual location in the image buffer.
