Abstract: An ocean fertilizer for the indirect sequestration of carbon dioxide in the ocean comprises a compound containing iron, a compound containing nitrogen, a compound containing phosphorus, a magnesium salt, and at least one of an ammonia oxidizing bacteria and a nitrite oxidizing bacteria, or both types of bacteria.

Abstract: A sorter for sorting a mixture having at least a first material with a first density from a second material with a second density different than the first density, comprising a container adapted to receive the mixture, a bed forming a base of the container provided with a series of openings extending from a bottom of the base to a top of the base, a granular layer positioned on the bed, and an air supply line providing air to the openings. In operation, the mixture is positioned above the granular layer, and the air supply supplies air to the granular layer at a rate sufficient to allow the sorting of the first material into a separate portion of the container from the second material.

Abstract: A structure alarm for sensing a change of status in the structure comprises an insert having a magnetic field, an encasing material encasing the insert, and a base attached to the encasing material and comprising a sensing assembly. Changes in the magnetic field correspond to changes in the status of the structure, and the sensing assembly is an inertial measurement unit that is adapted to send a signal corresponding to the changes in the magnetic field of the insert.

Abstract: An apparatus having components that are interconnectable without fasteners. A first component includes a male connection portion including a connection wall defining a non-circular, closed-geometric shape, and one or more grooves extending along a least a portion of an outer side of the connection wall. A second component includes a female connection portion including a capture wall defining a shape within which the connection wall fits in a first orientation and a second orientation. The second orientation is a fastened state achieved via a rotational twist action of the first component with respect to the second component. One or more protrusions extend inwardly from the capture wall. The one or more protrusions are sized to engage the one or more grooves of the connection wall of the first component when the connection wall is oriented in the second orientation within the capture wall.

Abstract: An auger includes a cylindrical body, a first channel helically defined in the cylindrical body, and a second channel helically defined in the cylindrical body. The auger further includes a first conduit defined in the cylindrical body. The first conduit includes a first sloped portion. The auger further includes a second conduit defined in the cylindrical body. The second conduit includes a second sloped portion. The auger further includes a first end mill formed in a first cavity defined in the cylindrical body, and a second end mill formed in a second cavity defined in the cylindrical body.

Abstract: A 3D object including a support structure formed with a mesh layer and an intermediate support structure; and one or more additive layers of substrate material formed via an axial growth process in which the substrate material formed a film over mesh holes in the mesh layer, thereby forming a continuous surface where the mesh holed previously existed.
