  • Patent number: 11952576
    Abstract: A novel method of diluting the structures in the cell population, such that individual cells, dependent on the activity of the structures, become single measurement devices. This can be applied to all Bacterial Microcomparments (“BMCs”), organelles, and macromolecules, and could provide a universal method for the design of novel ones and understanding of the diverse structures. In one aspect the present invention provides A method of creating a bacterial strain with inducible and detectable carboxysomes. The method includes the steps of incorporating a labeled carbon-fixation enzyme into the genome of a bacterium; deleting all or a portion of the ccm operon from the bacterium; and reintroducing a ccm operon comprising an inducible promoter to create a ?ccm+ strain.

  • Patent number: 11916534
    Abstract: A moveable micromachined member of a microelectromechanical system (MEMS) device includes an insulating layer disposed between first and second electrically conductive layers. First and second mechanical structures secure the moveable micromachined member to a substrate of the MEMS device and include respective first and second electrical interconnect layers coupled in series, with the first electrically conductive layer of the moveable micromachined member and each other, between first and second electrical terminals to enable conduction of a first joule-heating current from the first electrical terminal to the second electrical terminal through the first electrically conductive layer of the moveable micromachined member.

  • Patent number: 9114626
    Abstract: A method for recycling ink in an inkjet printer includes combining purged inks having two or more colors with black ink to form a mixed ink. The printer identifies an optical characteristic of the mixed ink and compares it to the optical characteristic for black ink. A controller for the printer adjusts the operation of the printer to form ink images having an optical characteristic that is closer to black ink than ink images formed with the mixed ink alone.
    Type: Grant

  • Patent number: 8714721
    Abstract: In an inkjet printer, an ink reclamation apparatus receives ink emitted from at least one printhead. The ink reclamation apparatus includes an ink receptacle and a liquid path member that extends from the ink receptacle to contact the face of at least one printhead proximate to a plurality of inkjets in the at least one printhead. The liquid path member draws liquid ink from the plurality of inkjets and the liquid ink enters the ink receptacle. The ink reclamation apparatus returns the ink to a reservoir in the printhead and reduces or eliminates wasted ink during operation of the at least one printhead.

  • Patent number: 8702186
    Abstract: A method for recirculating ink in an inkjet printer includes applying air pressure to an ink supply to expel liquid ink through a plurality of inkjets in the printhead. An ink receptacle that is positioned at a predetermined distance from the inkjets collects the expelled ink. The ink receptacle moves into fluid communication with an ink supply, and the ink collected in the ink receptacle enters the ink supply.
