  • Patent number: 12411870
    Abstract: Systems and methods are provided to classify activities into clusters. The systems and methods access data representing activity on a network site and generate, based on the data, a plurality of feature sets representing periods of activeness on the network side. The systems and methods form a subset of the plurality of feature sets by reducing dimensionality of the plurality of feature sets. The systems and methods generate a plurality of clusters of the subset of the plurality of feature sets, each cluster being associated with a label representing a different type of activeness on the network site, and generate a database query set based on the plurality of clusters and the plurality of feature sets to classify one or more activities on the network site into one of the plurality of clusters.

  • Publication number: 20220355319
    Abstract: A system and method for delivering materials for deposition is described. The system includes reservoirs for holding materials, heating elements for liquefying the materials (unless they are to be delivered as solids). Once in a desired state, pressure and material delivery systems to move the materials to a deposition nozzle. In the deposition nozzle, or thereabouts, the materials combine and are prepared to be deposited. An agitation element is used to break up the material and push it out of the nozzle tip in an atomized or droplet form. Changes in the material composition/concentration result in adjustment in heat, pressure or deposition agitation.

  • Publication number: 20220250323
    Abstract: An advanced multi-material capable deposition apparatus, system and method is described. The deposition apparatus and system include a print nozzle and material delivery path to deposit material of varying characteristics. An extrusion system processes the material under while controlling material and system variables based on sensor feedback to ensure a desired print. An actuation mechanism is used to control deposition of the material from the nozzle. A controller adjusts operational variables based on designed and measured material characteristics including print settings and environmental variables to precisely deposit the material in the form of an object.

  • Publication number: 20190217538
    Abstract: An atomized, functionally graded multi-material capable deposition apparatus, system and method is described. The deposition apparatus and system include a print nozzle and material delivery path to deposit material of varying characteristics. An internal chamber within the print nozzle receives the material under pressure and temperature control. An actuation mechanism within the print nozzle is used to control deposition of the material from the nozzle. A controller adjusts the temperature, pressure and actuation frequency based on material characteristics and print settings to precisely deposit the material in the form of an object.

  • Publication number: 20070270621
    Abstract: A process for producing industrially important chemicals from renewable resources is disclosed. This “biobased” process employs readily available, renewable resources comprising fatty acids rather than exploiting fossil sources, such as coal and petroleum. In one embodiment of the process 1-octene, along with methyl-9-decenoate and butadiene, is produced from linoleic acid via an enzymemediated isomerization reaction, followed by a metathesis reaction with ethylene. Linoleic acid can be isolated from vegetable oils, such as soybean oil.
