Abstract: Various aspects include electric generators configured to boost electrical output by leveraging electron avalanche generated by a high energy photon radiation source. In various aspects, an electric generator includes a stator and a rotor positioned within the stator, wherein the stator and rotor are configured to generate electric current when the rotor is rotated, and a high energy photon source (e.g., a gamma ray source) positioned and configured to irradiate at least a portion of conductors in the rotor or stator. In some aspects, the stator generates a magnetic field when the electric generator is operating, and the rotor includes armature windings configured to generate electric current when the rotor is rotated. In some aspects, the high energy photon source includes cobalt-60 and/or cesium-137.

Abstract: Aspects relate to systems and methods for providing information about a person's physiological signals to that person (and/or others) as they travel through various venues of their daily work and play life. Ubiquitous physiological feedback incentivizes the person to regulate their cognitive and/or emotional states to better perform various tasks. The feedback also provides them with practice opportunities throughout their day to further develop a psychophysiological self-regulation skill set. Obtaining pervasive physiological feedback throughout the environment may be achieved through the person's use and/or interaction with wearable or otherwise mobile physiological monitoring devices or systems and with other systems that may be embedded in environments through which the traveler visits during the course of their day. Such systems may experience functionality changes in response to an individual's physiological signals via biocybernetic adaptation.

Abstract: A composite material may be prepared from a solid polymeric binder and a solid filler by feeding into an extruder the solid polymeric binder at a first feed rate and the solid filler at a second feed rate. The extruder extrudes an extrudate of the solid polymeric binder and solid filler to form the composite material. The composite material has a binder to filler ratio determined by the first feed rate and second feed rate. The solid polymeric binder and solid filler have different densities. Feeding the solid polymeric binder at the first feed rate and the solid filler at the second feed rate distributes the solid filler substantially homogeneously throughout the composite material.

Abstract: This application describes an apparatus and system for a Wide band end launcher to convert a signal in a coaxial line to a CPW line. The apparatus uses a transition zone which gradually tapers in two inclined planes from the coaxial line to the CPW line, connecting the central conductor of the coaxial line to the central conductor of the CPW line. In addition, the outer conductor of the coaxial line is connected to the ground plates of the CPW line. This allows for high bandwidth transfers between the two types of lines for accurate measurements and other purposes.

Abstract: An arrayed waveguide for a photonic integrated circuit has a single optical path with serially connected delay lines. Different delayed optical paths or channels are periodically split off from the serially connected optical delay path. This has the net result of requiring much less space on-chip for comparable optical path differences with high spectral resolution.

Abstract: The present disclosure presents various additive manufacturing systems and methods. One such method comprises obtaining a build file containing instructions to additively manufacture a component; generating at least one point field; computing a spatter exposure metric from the at least one point field to quantify a risk of spatter induced porosity throughout a build; and updating the at least one point field with the spatter exposure metric computed. Computing the spatter exposure metric may include selecting at least one principal point from the at least one point field; determining at least one neighborhood using an additive manufacturing model search algorithm for the at least one principal point; and integrating a pyriform kernel function for the at least one principal point and the at least one neighborhood. Other systems and methods are also disclosed.

Abstract: A real-time reference free background oriented schlieren system is provided. One embodiment includes a display device capable of generating an image pattern projected onto a retroreflective background. A beam splitter is used to transmit a portion of the projected image pattern towards a reference image sensor and another portion of the image pattern towards the retroreflective background and past a density object. The retroreflective background reflects the projected pattern back through the beam splitter and onto a signal imaging sensor. Collected data from the reference image sensor and the signal image sensor may be processed in real-time. The image pattern may be altered as necessary without requiring a new reference image, reducing the amount of time required to set up and adjust the system. A display device may be capable of switching between a schlieren visualization capability to a shadowgraph system allowing for the use of two different imaging techniques.

Abstract: The subject invention is an electrostatic plant watering system for the delivery of water and nutrients to the roots of plants. The system provides water or another fluid from a fluid source or container using a pump. The pump provides a pressurized fluid at a constant flow rate through a nozzle at a low pressure, which sprays a fine mist of particles through a conductive metallic ring that is electrically charged by a voltage source. As the fluid particles pass through the center of the electrically charged ring, the particles themselves become charged, allowing them to attach to the roots of a target plant positioned at a selected distance away from the electrostatic plant watering system.
