Abstract:
A flexible detection/test tape includes a first flexible conductive layer, and a second flexible conductive layer positioned opposite the first conductive layer. A plurality of at least one of sensors, actuators or transducers are positioned between and are bonded to the first flexible conductive layer and the second flexible conductive layer. An insulative material is inserted around the plurality of at least one of the sensors, actuators or transducers. An electrical contact network connects to the first flexible conductive layer and the second flexible conductive layer, whereby power and control signals are provided to the flexible detection/test tape. In an alternative embodiment, a method for producing a detection/test tape includes depositing a material onto a surface of at least one first substrate to form a plurality of element structures. Electrodes are deposited on a surface of each of the plurality of element structures, and the element structures are bonded to a second substrate, where the second substrate is conductive or has a conductive layer, and the second substrate is carried on a carrier plate. The at least one first substrate is removed from the element structures and second side electrodes are deposited on a second surface of each of the plurality of element structures. An insulative material is inserted around the element structures to electrically isolate the two substrates used to bond the element structures. A second side of the element structures is then bonded to another substrate, where the other substrate is conductive or has a conductive layer. Thereafter, the carrier plate carrying the second substrate is removed.
Abstract:
Methods for testing proper operation of drop ejection units in a multi-ejector system are provided to determine whether the drop ejectors have been properly filled and/or the ejectors are emitting fully formed droplets. The method include testing the ejectors prior to drop ejection. In this method, a priming system is ejected onto a test substrate to allow a scanner to determine the existence of the fluids at selected locations.
Abstract:
This invention relates to a method and apparatus for acoustic ink printing using a bilayer configuration. More particularly, the invention concerns an acoustically actuated droplet emitter (40) which is provided with a continuous, high velocity, laminar flow of cooling liquid (23) in addition to a stagnant pool of liquid (32) to be emitted as droplets.
Abstract:
A system for improving the uniformity of ink droplets delivered from a plurality of droplet sources on a printhead is described. The system includes a cooling system that compensates for nonuniform heating effects in a printhead which results in nonuniform temperatures. The distribution of the cooling system, and the effectiveness of the cooling system is set to maintain an approximately uniform ink temperature across the printhead.
Abstract:
A material deposition head (200; Fig.6) having lithographically defined ejector units (10). Beneficially, each ejector unit includes a plurality of lithographically defined droplet ejectors (10). Each droplet ejector (10) includes an acoustic transducer (20) and a lens (30) for focussing the acoustic energy onto the surface of a liquid (14). Furthermore, methods of fabricating such lithographically defined material deposition heads (200; Fig.6) are also described.
