Abstract: A method for configuring an associative array within a molecular-junction-nanowire crossbar, and nanoscale associative arrays configured by the method Keys are encoded as field-effect transistors selectively configured within the molecular-junction-nanowire crossbar, and values associated with keys are encoded as diodes selectively configured at molecular-junction-nanowire-crossbar junctions. Keys input into key registers result in a current signal indicating whether or not the key is stored within the associative array as part of a key/value pair and, if stored in the associative array, the value associated with the input key is output.

Abstract: A magnetic tool for manipulated conveyance over a surface for magnetic collection of ferrous articles has a three-sided channel which cooperates with an opposing plate to form a magnet housing for one or more magnets. The magnetically conductive channel is configured to direct magnet flux downward to optimize the attraction efficiency of the tool. Magnetic flux is further optimized by use of two magnets in the channel housing of opposite polarity. The channel also serves as the primary structural element of the tool for attachment of conveyance and manipulation means.

Abstract: A self-packaged magnetic tool assembly has protective components which also serve as retail packaging, to facilitate retail sales without the need for any extraneous or temporary packaging. The magnetic tool assembly has a permanently charged elongated rectangular-shaped magnet encased by two ferrous metal side plates along a length of the magnet, and a single non-magnetic stainless steel plate connecting the two side plates. The ferrous metal side plates act as the north and south poles of the magnet assembly. The magnet and metal plates are encased in a protective cover on all but the primary attracting surfaces of the magnet and the side plates, thereby reducing unwanted magnetic attraction to other surfaces of the tool. Two removable rectangular plastic spacers are inserted over the primary attracting surfaces of the magnet and the side plates. The spacers serve as packaging elements which protect the primary attracting surface, and which can be selectively removed during use of the tool.

Abstract: A modular magnetic tool system utilizes one or more magnet modules and attachable components to enable selective assembly of a wide variety of magnetic tools. Channels of the magnet modules are connectable in series and in parallel, either by integral connectors or attachable components which can be selectively attached to the magnet modules singularly, in series, or in parallel to form different types of magnetic tools with different functions for different applications.

Abstract: A self-packaged magnetic tool assembly for use in picking up or lifting metallic objects includes integrally assembled protective components which also serve as retail packaging, to facilitate retail sales without the need for any extraneous or temporary packaging. In one embodiment, the magnetic tool assembly has a permanently charged elongated rectangular-shaped magnet encased by two ferrous metal side plates along a length of the magnet, and a single non-magnetic stainless steel plate connecting the two side plates. The ferrous metal side plates act as the north and south poles of the magnet assembly. The side plates also extend slightly past the permanent magnet material, thereby reducing direct contact between attracted objects and protecting the permanent magnet material. The magnet and metal plates are encased in a protective cover on all but the primary attracting surfaces of the magnet and the side plates, thereby reducing unwanted magnetic attraction to other surfaces of the tool.

Abstract: A magnetic sweeper device is constructed with a structural integrating bracket which provides structural interconnection between one or more magnets, conveyance devices such as wheels, and a manipulation device such as a handle. The bracket includes a main section against which one or more magnets are attached by through-fit fasteners, conveyance attachment structures at distal ends for attachment of wheels, and a centrally disposed stem for attachment of a handle. The bracket also functions to direct the magnetic field downward by attachment of the magnet to a lower underside surface of the main section of the bracket. A magnet cover can also be attached to the magnet by the magnet supporting fasteners attached to the bracket.

Abstract: A magnet tool and method of assembly, utilizes an alignment insert in a central opening of the magnet to coaxially align fastener guide holes through polar plates or protective covers on opposing planar sides of the magnet and a fastener guide hole in the insert, whereby insertion of the fastener through the guide holes laterally aligns the components of the assembly without the use of adhesive. A method of assembly of the tool without the use of adhesive is also described.
