An ink printing process employs per-nozzle droplet volume measurement and processing software that plans droplet combinations to reach specific aggregate ink fills per target region, guaranteeing compliance with minimum and maximum ink fills set by specification. In various embodiments, different droplet combinations are produced through different print head/substrate scan offsets, offsets between print heads, the use of different nozzle drive waveforms, and/or other techniques. Optionally, patterns of fill variation can be introduced so as to mitigate observable line effects in a finished display device. The disclosed techniques have many other possible applications.

Nozzle-droplet combination techniques to deposit fluids in substrate locations within precise tolerances

An ink printing process employs per-nozzle droplet volume measurement and processing software that plans droplet combinations to reach specific aggregate ink fills per target region, guaranteeing compliance with minimum and maximum ink fills set by specification. In various embodiments, different droplet combinations are produced through different printhead/substrate scan offsets, offsets between printheads, the use of different nozzle drive waveforms, and/or other techniques. These combinations can be based on repeated, rapid droplet measurements that develop understandings for each nozzle of means and spreads for expected droplet volume, velocity and trajectory, with combinations of droplets being planned based on these statistical parameters. Optionally, random fill variation can be introduced so as to mitigate Mura effects in a finished display device. The disclosed techniques have many possible applications.

Techniques for print ink droplet measurement and control to deposit fluids within precise tolerances

An imaging apparatus includes a print engine having a printhead that generates ink drops, and a printhead carrier that carries the printhead in a first direction and in a second direction opposite the first direction. A controller determines an initial print direction based on ink drop information obtained by printing patches in the first direction and in the second direction, wherein the ink drop information includes a respective chromatic value of each of the patches. The controller is operatively coupled to the print engine to print an image based on the initial print direction.

Imaging apparatus and method for reducing banding

A controller for controlling a microfluidic device. A first computing device receives commands from a user interface in a relatively high level protocol using a standardized command language, converts the commands from the standardized command language into a relatively mid-level protocol, sends the commands in the relatively mid-level protocol, receiving data, converts the data into the standardized command language, and sends the data to the user interface according to the standardized command language. A second computing device receives the commands from the first computing device in the relatively mid-level protocol, converts the commands from the relatively mid-level protocol to at least one relatively lower level protocol that is understood by a microfluidic device that is connected to the controller, receives data from the microfluidic device, and sends the data to the first computing device.

Fluidic device control

A micro-fluidic device. The device includes a semiconductor substrate attached to a fluid supply source. The substrate contains at least one vaporization heater, one or more bubble pumps for feeding fluid from the fluid supply source to the at least one vaporization heater, a fluid supply inlet from the fluid supply source in fluid flow communication with each of the one or more bubble pumps, and a vapor outlet in vapor flow communication with the at least one vaporization heater. The one or more bubble pumps each have a fluid flow path selected from a linear path, a spiral path, a circuitous path, and a combination thereof from the supply inlet to the at least one vaporization heater.

Method and apparatus for metering and vaporizing fluids

A vaporization device, including a fluid supply containing a vaporizable fluid; a plurality of bubble pumps operative to pump fluid from the fluid supply to outlets of the bubble pumps; and a fluid vaporization heater located adjacent the outlets of the bubble pumps to receive fluid from the bubble pumps.

A location-based address adapter for use in a system to facilitate communication between a host computer and one peripheral device of a plurality of peripheral devices includes a body and an electrical circuit. The body is removably attached to one peripheral device at a time. The electrical circuit includes a communications interface circuit and an adapter memory circuit. The communications interface circuit has a respective pass-through wired connection between each of a plurality of input connectors and a plurality of output connectors to facilitate bi-directional communications between the host computer and the peripheral device. The adapter memory circuit stores a unique physical location address for association with a physical location associated with the peripheral device to which the body is attached. The unique physical location address is a non-network based address. The memory circuit has a memory connector to facilitate direct electrical communicative connection only with the respective peripheral device.
