Abstract: Systems and methods for supplying primary fuel and secondary fuel to an internal combustion engine may include supplying a first amount of the primary fuel and a second amount of the secondary fuel to the internal combustion engine. The system may include a first manifold to provide primary fuel to the internal combustion engine, and a primary valve associated with the first manifold to provide fluid flow between a primary fuel source and the internal combustion engine. A second manifold may provide secondary fuel to the internal combustion engine, and a fuel pump and/or a secondary valve may provide fluid flow between a secondary fuel source and the internal combustion engine. A controller may determine a total power load, the first amount of primary fuel, and the second amount of secondary fuel to supply to the internal combustion engine to meet the total power load.

Abstract: Roll-dispensed stock containers are provided. The roll-dispensed stock containers can include a recessed cutting track positioned along a length of a support wall of the container. The support wall can also include one or more apertures positioned adjacent to the recessed cutting track configured to receive a base of a slidable cutter movable along an elongated slot in a lid of the container. The base of the slidable cutter is captured by the recessed cutting track during a cutting operation to secure the lid in a closed position and to apply constant pressure against roll-dispensed stock as it is cut. Roll-dispensed stock containers of the present disclosure can also include a coating on one or more surfaces thereof. The coating can be formed from a material selected to reduce surface friction, increase rigidity, disperse forces associated with a cutter, and/or otherwise enhance characteristics of the container.

Abstract: A harvester travels along a route within a field and selectively harvests edible crowns ready for harvesting. As the harvester travels along the route, a position of the harvester and/or the edible crowns may be determined using an encoder, imaging device(s), and/or navigational system(s). For example, image(s) captured by the imaging device(s) may be used to determine a location of the edible crowns and/or global positioning satellite (GPS) coordinates may indicate a location of the harvester within the field. These locations may be used for instructing harvesting components to harvest the edible crowns. For example, the harvester may include robotic arms having end effectors that harvest the edible crowns. Knowing the location of the edible crowns and/or the harvester therefore allows for the accurate placement of the end effectors for harvesting the edible crowns.

Abstract: In some embodiments, a method can include connecting, via an application stored in a browser cache of a presenter compute device, to a synchronized mesh server endpoint. The synchronized mesh server endpoint establishes a session between the presenter compute device and multiple audience compute devices. The method can further include formatting each page from multiple pages of a portable document format (PDF) to a unique scalable vector graphics (SVG) representation from multiple SVG representations, such that the multiple SVG representations are stored in the browser cache when the multiple pages are formatted. The PDF file includes the multiple pages and multiple tags. The method further includes uploading the multiple SVG representations and the multiple tags to the synchronized mesh server endpoint. The method further includes clearing the application from the browser cache, after the uploading and when an end-of-session message is received from the synchronized mesh server endpoint.

Abstract: A method and apparatus for acquiring and parsing data into categories responsive to receipt of at least one prospectus of a variable or non-fixed annuity contract for storage in an annuity master database. Once annuity contract data is received in the annuity master database, the data is analyzed and a recommended annuity contract value is forecast using one of trend-line projection and Monte Carlo simulation. A result is a filtering and listing of at least one recommended annuity or, further, a ranking of annuity contracts available from various carriers recommended for an annuity contract purchaser responsive to an annuity contract purchaser profile.

The hydrogel may include lactose, which may be provided by a milk permeate waste stream from the dairy or food processing industry.

Abstract: A gateway includes memory configured to store computer-readable program code; and processing circuitry configured to access the memory and execute the computer-readable program code. The gateway is connected or connectable to a low-power wide area (LPWA) network. The gateway is caused to transmit a common timing reference at a constant interval that delineates an epoch including timeslots assignable to network nodes and a free-for-all interval. The gateway is also caused to join a network node to the LPWA network based on the common timing reference and is further caused to receive a join message including a measure of received signal strength or quality of the common timing reference at the network node. The gateway is also caused to assign one or more timeslots within the epoch, a frequency, a channel, or a modulation to the network node based on the measure of received signal strength or other quality.

Abstract: Provided in this disclosure is a selectively replaceable spindle for a banister. The spindle includes a generally longitudinal body having first and second ends for respectively engaging recesses on opposing surfaces of a handrail and a lower rail of a banister. A securement mechanism is attached to either of the first or second ends of the body, for releasably securing the respective end to the respective recess. The securement mechanism includes a spring-biased clip extending from the respective end of the body that is urged into contact with the respective recess. A lever is attached to the spring-biased clip for compressing an internal spring and enabling retraction of the spring-biased clip from the respective recess. The lever thus releases the secured one of the first or second ends of the generally longitudinal body from the respective one of the first or second recesses, thereby permitting removal of the spindle.
