  • Patent number: 12166147
    Abstract: Disclosed are embodiments of a thin-film photovoltaic technology including a single-junction crystalline silicon solar cell with a photonic-plasmonic back-reflector structure for lightweight, flexible energy conversion applications. The back-reflector enables high absorption for long-wavelength and near-infrared photons via diffraction and light-concentration, implemented by periodic texturing of the bottom-contact layer by nanoimprint lithography. The thin-film crystalline silicon solar cell is implemented in a heterojunction design with amorphous silicon, where plasma enhanced chemical vapor deposition (PECVD) is used for all device layers, including a low-temperature crystalline silicon deposition step. Excimer laser crystallization is used to integrate crystalline and amorphous silicon within a monolithic process, where a thin layer of amorphous silicon is converted to a crystalline silicon seed layer prior to deposition of a crystalline silicon absorber layer via PECVD.

  • Publication number: 20240307110
    Abstract: Devices for therapeutic nasal neuromodulation and associated systems and methods are disclosed herein. A system for therapeutic neuromodulation in a nasal region configured in accordance with embodiments of the present technology can include, for example, a shaft and a therapeutic element at a distal portion of the shaft. The shaft can locate the distal portion intraluminally at a target site inferior to a patient's sphenopalatine foramen. The therapeutic element can include an energy delivery element configured to therapeutically modulate postganglionic parasympathetic nerves at microforamina of a palatine bone of the human patient for the treatment of rhinitis or other indications. In other embodiments, the therapeutic element can be configured to therapeutically modulate nerves that innervate the frontal, ethmoidal, sphenoidal, and maxillary sinuses for the treatment of chronic sinusitis.

  • Patent number: 11025747
    Abstract: A pattern-based content request routing system is described herein that can route content requests according to user and/or user device behavior. For example, the routing system can cause requests for byte-heavy content to be routed to content delivery networks (CDNs) that have a sufficiently large cache width—even if such CDNs are not the geographically-closest CDNs to the source of the requests—to reduce the negative impact on content retrieval latency for other user devices that may be requesting other content. In particular, CDNs may store access logs that indicate the types of content requested by various user devices. The routing system can retrieve and analyze the access logs to identify patterns of requests. The routing system can then evaluate the properties of various CDNs, determine which CDNs may be suitable for the identified patterns of requests, and instruct a DNS server to route user devices accordingly.

  • Publication number: 20200328366
    Abstract: Electromagnetic energy collecting devices are described wherein a plasmonic near field resonating system absorbs light and transfers the light energy by plasmonic near field resonance to a semiconducting material that then separates the charge. The charge is then transported out of the device, converting light energy into electrical energy. The multiple nanoparticle plasmonic resonators are closely coupled with an electrically-conductive layer that creates electromagnetic resonances that provide for near perfect absorption of the incoming light. The device can be used both as an optical sensor and as a photovoltaic electromagnetic energy to electrical energy converter.
