  • Patent number: 11676091
    Abstract: Embodiments are directed to computer systems and methods that provide a data-driven approach to product benchmarking. The systems and methods identify a product being developed on a product development platform. The systems and methods repeatedly evaluate products similar in operation to the identified product. In response to the evaluation, the systems and methods automatically determine current performance capabilities of the similar products and digitize the determined current performance capabilities as current benchmark parameters in a central database integrated within the platform. The systems and methods generate output, by an application of the platform, based on searching the current benchmark parameters in the database, and develop functions and parts for the identified product using the generated output.

  • Publication number: 20220004993
    Abstract: An application updates a status of a project with a plurality of tasks, where each task has at least one deliverable. The project status is updated in real-time based on a deliverable status of at least one task deliverable. For each project task with at least one deliverable, a plurality of deliverable lifecycle states to be tracked are defined. Each tracked deliverable lifecycle state is mapped to a percentage completion of a project task. A weightage is assigned to each deliverable according to an importance of the deliverable. A changed lifecycle state is received for a deliverable, and the project task percentage completion status is automatically adjusted according to a product of the changed lifecycle state and the assigned weightage.

  • Patent number: 10746197
    Abstract: Variable flow rate fuel ejectors, and methods of use therefore, are disclosed. One variable flow rate ejector includes a primary nozzle, a needle, a motor, a first stop portion, and a first impact-absorbing portion. The primary nozzle is connected to a first inlet chamber to receive a first fluid and transmit a flow of the first fluid through the primary nozzle opening. The needle is disposed to create a gap between the tapered portion of the needle and the primary nozzle opening. The motor is coupled to axially move the needle to vary a size of the gap. The first stop portion delimits the axial movement of the needle in a direction of retraction of the needle from the primary nozzle opening. The first impact-absorbing element is positioned to contact the first stop portion or the needle, respectively, when the needle is fully retracted from the primary nozzle opening.

  • Publication number: 20070238010
    Abstract: The present invention relates to novel methods for producing a nano-porous gas diffusion media, compositions thereof, and devices comprising the same. The nano-porous gas diffusion media of the invention is produced using photolithographic techniques to create a solid substrate comprising a plurality of nano-scale (1 nm-300 ?m) pores or holes that allow for the diffusion or exchange of molecules, gases, and/or liquids through the substrate. The nano-porous diffusion media of the invention also displays superior electro- and thermal conductivity, and increased durability and performance. In some embodiments, the nano-porous diffusion media of the invention is also coated with a self-assembling monolayer (SAM) of organic molecules to further improve its physical characteristics.

  • Publication number: 20060254983
    Abstract: A mixing vessel contains a septum, dividing a first chamber from a second chamber. By relatively moving the septum with respect to the ends of the vessel, and flowing a fluid through the septum, the fluid is treated as it moves from the first chamber to the second chamber. The particular configuration of the septum allows for treatments such as mixing, reacting, heating, and cooling, as well as filtering of the fluid.
