  • Publication number: 20190060692
    Abstract: A trampoline is disclosed having a zipper, one half of which is attached to the outer portion of the jumping surface, the other half attached to the lower portion of the protective netting, so that the jumping surface and protective netting can be connected in a continuous fashion. The zipper is an open type zipper design, and preferably begins and ends in a position in proximity to a pole from which the protective netting is suspended. A second zipper is disclosed in the protective netting to allow for an open position and a closed position, such that when in the closed position, the second zipper tab is in proximity to the first zipper tab when closed, so that the two can be tethered together to discourage the zippers from becoming unzipped.

  • Publication number: 20180371632
    Abstract: A high purity lithium metal thin film and a process for controlling the morphology of the high purity lithium metal thin film are provided. In a general embodiment, the present disclosure provides a high purity lithium metal thin film having a controlled thickness and morphology. The high purity lithium metal thin film is produced by electrolytic deposition of lithium using a selective lithium ion conducting layer. The morphology of the lithium metal thin film can be controlled by varying the current rate used for deposition. The present lithium metal films advantageously provide a high purity lithium metal film in which the thickness and/or morphology of the film can be altered depending on the desired application.

  • Publication number: 20180133460
    Abstract: Devices, systems, and methods for specializing, monitoring, and/or evaluating therapeutic nasal neuromodulation are disclosed herein. A targeted neuromodulation system configured in accordance with embodiments of the present technology can include, for example, an evaluation/modulation assembly at a distal portion of a shaft and including a plurality of electrodes. The electrodes are configured to emit stimulating energy at frequencies for identifying and locating target neural structures and detect the resultant bioelectric properties of the tissue. The system can also include a console that maps locations of the target neural structures. The evaluation/modulation assembly can then apply therapeutic neuromodulation energy in a highly tailored neuromodulation pattern based on the mapped locations of the target neural structures. Accordingly, the system provides therapeutic neuromodulation to highly specific target structures while avoiding non-target structures to reduce collateral effects.

  • Publication number: 20180130867
    Abstract: A magnetic isolator is described. The magnetic isolator may comprise a top conductive coil, a bottom conductive coil, and a dielectric layer separating the top conductive coil from the bottom conductive coil. The top conductive coil may comprise an outermost portion having multiple segments. The segments may be configured to reduce the peak electric field in a region of the dielectric layer near the outer edge of the top conductive coil. The top conductive coil may comprise a first lateral segment, and a second lateral segment that is laterally offset with respect to the first lateral segment. The first lateral segment may be closer to the center of the top conductive coil than the second lateral segment, and may be closer to the bottom conductive coil than the second lateral segment. The magnetic isolator may be formed using microfabrication techniques.
