  • Publication number: 20240181449
    Abstract: A microfluidic device includes a first channel, second channels, and a transition channel splitting the first channel into the second channels. The transition has a first end fluidically connected to the first channel and a second end fluidically connected to the second channels. The transition channel expands in width from a width of the first channel at the first end to no less than a sum of widths of the second channels at the second end so as to promote fluid flow from the first channel to the second channels.

  • Publication number: 20240165617
    Abstract: A microfluidic device includes a first channel having a first width and a second channel having a second width greater than the first width. The microfluidic device includes a transition channel having a first end fluidically connected to the first channel and a second end fluidically connected to the second channel. The transition channel expands in width from the first width to the second width so as to promote fluid flow from the first channel to the second channel.

  • Patent number: 11059290
    Abstract: A fluid ejection device includes a fluid slot, three laterally adjacent fluid ejection chambers each having a drop ejecting element therein, a fluid circulation path communicated with each of the three laterally adjacent fluid ejection chambers, and a fluid circulating element within the fluid circulation path, with at least two laterally adjacent fluid ejection chambers of the three laterally adjacent fluid ejection chambers to substantially simultaneously eject drops of fluid therefrom such that the drops of fluid are to coalesce during flight.
