  • Publication number: 20240078561
    Abstract: Methods, systems, and techniques for agricultural greenhouse gas estimation. Farm data in the form of at least one of revenue generated by a farm, crop information for one or more crops grown on the farm, and land use/farm practice data for land used on the farm to grow the one or more crops is obtained. An emissions estimate is determined based on the obtained data and caused to be displayed to the user via a graphical user interface. A user may be a person responsible for managing multiple farms. That user may be presented with aggregate emissions-related information for all farms, including projected future emissions under various scenarios, and may also iteratively experiment with different farm data values in order to attempt to reduce projected emissions or increase data quality/emissions estimate accuracy.

  • Patent number: 10518037
    Abstract: An injection device includes a housing having a receptacle for a vessel for holding injection fluid; an operator-manipulated element for setting an injection dose; a dosing member rotatable about a longitudinal center axis relative to the housing when setting the injection dose; a feed part; and, a latching unit acting between the feed part and housing. The dosing member has a zero position whereat no dose is set and an injection position whereat an intended dose of injection fluid is set. A spring acts between the dosing member and the housing to return the dosing member from an intermediate position to the injection position or a zero position.

  • Publication number: 20180037862
    Abstract: The present invention provides a process for producing a fermentation product from a lignocellulosic feedstock. The process comprises soaking a lignocellulosic feedstock in an aqueous solution to produce a soaked feedstock. The soaked feedstock is at least partially dewatered and the at least partially dewatered feedstock is subjected to pretreating in the presence of sulfur dioxide, sulfurous acid or a combination thereof to produce a pretreated feedstock composition. The pretreated feedstock composition is fed to an enzymatic hydrolysis in which the concentration of dissolved solids fed to the enzymatic hydrolysis is at least 50% (w/w) of the concentration of dissolved solids in the pretreated feedstock composition. The cellulose in the pretreated feedstock composition is hydrolyzed with cellulase enzymes in the presence of the dissolved solids to produce glucose. The glucose is fermented to produce the fermentation product.

  • Patent number: 8670387
    Abstract: Within an access services network (ASN) providing wireless access services to an access terminal and a base station communicatively coupled to an ASN gateway, a new functional process identified as an “R6 controller” is provided within the framework. The R6 controller includes both a controlling entity process residing and executing within the ASN gateway and an agent entity process residing and executing within the base station. The R6 controller entities monitor the R6 reference point therebetween and may execute a keep-alive procedure for determining the status of the R6 interface. If a problem is detected, interested client applications are notified and further actions (e.g., initiate handover process, notify ATs, etc.) may be taken. Optionally, the R6 controller entities function as gateways enabling centralized processing for messages transmitted between peer instances of other client application processes spanning the base station—ASN gateway pair.
