Abstract: Described herein are systems and methods relating to three-dimensional (3D) cell manufacturing utilizing a 3D growth media. According to aspects of the present disclosure, pluralities of cells and ECM components can be printed into a bioreactor as a sheet. Sheets can be retrieved, digested, split, and re-printed, thereby expanding the number of cells in an efficient manner that conserves space in a tissue culture incubator, conserves bioreactor consumables, and consumes nutrients required for cell maintenance and growth.

Abstract: A contactless charging system for smart garments having coils whose centroids are not colinear. Folding a coil in half through its centroid will null out its inductance. A smart garment having 3 coils that have centroids that are not colinear is proposed. Accordingly, there is no single folding line that intersects all 3 centroids thereby nullifying inductance. Power can be combined with one or more rectifiers such that power is not cancelled. The present disclosure is suitable for any charging environment or apparatus, such as, drawer or hanger.

Abstract: Various examples are provided for portable neutron imaging. In one example, a portable neutron-imaging system is described. A compact neutron source assembly can comprise an ion-beam bombardment source generating an isotropic source of monoenergetic neutrons. The neutron-imaging system does not include a moderator or collimator. Instead, the emission source and image-capture apparatus are placed in close proximity to an object to be imaged. Quality images were obtained with short exposure times of less than 20 seconds.

Abstract: The present disclosure relates to systems and methods for electrodynamic wireless power receivers. In some examples, a wireless power receiver electromechanically converts energy from a magnetic field. The wireless power receiver includes a planar suspension structure and at least one magnet. The planar suspension structure is tuned to cause oscillation of the at least one magnet at a resonance frequency based on a frequency of the time-varying magnetic field to generate electrical energy in the wireless power receiver.

Abstract: Memristive learning concepts for neuromorphic circuits are described. In one example case, a neuromorphic circuit includes a first oscillatory-based neuron that generates a first oscillatory signal, a diode that rectifies the first oscillatory signal, and a synapse coupled to the diode and including a long-term potentiation (LTP) memristor arranged in parallel with a long-term depression (LTD) memristor. The circuit further includes a difference amplifier coupled to the synapse that generates a difference signal based on a difference between output signals from the LTP and LTD memristors, and a second oscillatory-based neuron electrically coupled to the difference amplifier that generates a second oscillatory signal based on the difference signal. The circuit also includes a feedback circuit that provides a feedback signal to the LTP and LTD memristors based on a difference or error between a target signal and the second oscillatory signal.

Abstract: The present disclosure describes various embodiments of systems, apparatuses, and methods of monitoring wind and water properties. For one such weather monitoring system, a weather monitoring station comprises an upper mast section having an instrumentation package, wherein the instrumentation package includes an orientation sensor, communications circuitry, a wind velocity sensor, and a control unit that is configured to at least receive sensor data and transmit communication data via the communications circuitry. The weather monitoring station further includes at least one lower mast section that is coupled to the upper mast section, and an anchoring system that is coupled to the lower mast section, wherein the anchoring system includes at least one subsurface anchor for inserting into a ground surface within a littoral zone of a coastal area. Other systems, apparatuses, and methods are also provided.

Abstract: Provided herein is a method and apparatus for venting of intravenous tubing to remove air bubbles, and more particularly, to a venting valve that allows air bubbles to escape along a venting path while not permitting fluid passage through the venting path. An example air extraction device may include: a chamber; a fluid inlet to convey fluid from intravenous tubing into the chamber; a fluid outlet to convey fluid from the chamber to intravenous tubing for supplying to a patient; a top portion of the chamber; a branch tube extending from the top portion of the chamber, where the branch tube receives air from the fluid in the chamber; and a ball received within the chamber, where the ball is configured to rise with an influx of fluid to the chamber from the fluid inlet and to seal off the branch tube from the chamber in response to the fluid level rising to the top portion of the chamber.

Abstract: The present disclosure describes various embodiments of systems, apparatuses, and methods of fabricating a metamaterial-inspired dual-function loop antenna. One such antenna device comprises a loop antenna and a metamaterial slab integrated on top of the loop antenna. Accordingly, the metamaterial slab metamaterial has a negative refractive index value at a first frequency and a near zero refractive index at a second frequency, wherein the first frequency is less than the second frequency, each unit cell of the metamaterial slab is coupled to a capacitor in parallel, the first frequency is attributed to a capacitance value of the capacitor, and the second frequency is attributed to a dimension of the unit cell. As such, the antenna device is configured to receive wireless power transfer signals over the first frequency and wireless communication signals over the second frequency. Other apparatuses, systems, and methods are also presented.
