Abstract: Recycled carbon fibers are processed by rotational tumbling in a mixture with binder material to prepare fiber-containing particles having a dual-tapered shape and general alignment of fibers with a longitudinal direction of the particles. Bulk products including such fiber-containing particles are compounded with polymer and pelletized to prepare fiber-reinforced composite pellets, which are useful for applications such as injection molding to prepare molded products of carbon fiber-reinforced composite material with recycled carbon fibers.

Abstract: An augmented reality method and system enables sponsors within a defined geographic area to insert enhanced augmented reality objects into navigable views of a geographic area to form “communities” searchable by a common name or identifier. Users of the method and system situated outside the geographic area may then explore the community by entering the name or identifier of the community, navigating between images containing geolocated scenes taken from or representing the geographic area or community, and interacting with the augmented reality objects positioned within the images.

Abstract: Processing sized fiber products to recover reinforcing fibers by removing fiber sizing material from the reinforcing fibers. The processing includes first treating the sized fiber product with a normally-liquid first solvent for fiber sizing material followed by removal of the first solvent from the first solid residue including reinforcing fibers. The removal of the first solvent from the continuous reinforcing fibers may include heating the fibers and/or second treating the first solid residue with a normally-gaseous material contacted with the solid residue under conditions of temperature and pressure at which the normally-gaseous material is in a liquid or supercritical fluid form. The processing may be performed in a continuous manner to recover the continuous reinforcing fibers in a continuous form.

Abstract: Processing reinforcing fiber products to recover reinforcing fibers by removing other material, such fiber sizing material and/or matrix material from the reinforcing fibers. The processing includes cosolvent treating the reinforcing fiber product with a cosolvent composition including a normally-liquid first solvent portion and a normally-gaseous second solvent portion under conditions of temperature and pressure at which the cosolvent composition is in the form of a single fluid phase that is a liquid or a supercritical fluid. The processing may be performed in a continuous manner to recover the continuous reinforcing fibers in a continuous form.

Abstract: A condom package for a singular direction or removal of the contents thereof to assure its proper application onto a user. The package includes a container having a configuration with an essentially flat top side and a bottom side, the top side and the bottom side each having an external surface and an internal surface, the external surfaces of the top side and the bottom side facing in opposing directions, the internal surfaces facing each other, the internal surfaces having peripheral portions removably sealed to each other. The bottom side formed of a material more rigid than that of the top side, the bottom side having a shallow central well proportioned to hold and stabilize the condom.

Abstract: A floating-gate transistor array and method for programming the same. The floating-gate transistor array includes a plurality of transistors having a source, drain, and floating-gate, whereby the plurality of transistors is arranged into multiple rows and columns. Each row of transistors includes a row programming switch having an output connected to each floating-gate within the row, while each column of transistors includes a column programming switch having an output connected to each drain within the column. The source of each transistor is coupled with a source line corresponding to the specific row of the transistor. The row and column programming switches are utilized to select and program a desired floating-gate transistor. In an indirect programming method, two transistors share a floating gate, such that programming a programmer transistor modifies the current of an agent transistor, which is attached to the circuit, thereby permitting run-time programming.

Abstract: A large-scale field-programmable analog array (FPAA) for rapidly prototyping analog systems and an arbitrary analog waveform generator. The large-scale FPAA includes a floating-gate transistor array and a plurality of computational analog blocks (CABs), which may be adapted to set bias voltages for operational transconductance amplifiers (OTAs), adjust corner frequencies on the capacitively coupled current conveyors, set multiplier coefficients in vector-matrix multipliers, and a variety of other operations. The floating-gate transistors may be used as switch elements, programmable resistor elements, precision current sources, and programmable transistors. Accordingly, the floating-gate transistors within the array allow on-chip programming of the characteristics of the computational elements, while still maintaining compact CABs. The arbitrary analog waveform generator may include programmable floating-gate MOS transistors for use as analog memory cells to store samples of the waveforms.
