Abstract: In some aspects, deicer systems to distribute a deicing fluid along a roof of a building to limit ice dam formation can include: a pre-pressurized water source that provides pressurized water; a deicer solution source containing a deicer solution; a passive mixing system in fluid communication with the pre-pressurized water source and the deicer solution source, the passive mixing system being configured to combine the pressurized water and the deicer solution to form a deicer fluid; and one or more emitters configured to be disposed along the roof, the emitters being in fluid communication with the passive mixing system to receive the deicer fluid and dispense the deicer fluid along the roof. In addition, certain systems described herein can be run with an electric pump.

Abstract: A fluid deposition system is provided. The system comprises one or more electronic processors, and one or more electronic memories each electrically connected to at least one of the one or more processors and having instructions stored therein. The processor(s) is/are configured to access the memory or memories and execute the instructions stored therein such that the processor(s) is/are configured to: determine whether one or more predetermined criteria are met for initiating deposition of fluid onto an area of interest; when it is determined that the criteria is/are met, determine one or more operating parameters of the fluid deposition system to use in the deposition of the fluid onto the area of interest; and following the determination of the operating parameter(s), generate one or more electrical signals to cause the fluid to be deposited onto the area of interest in accordance with the determined parameter(s).

Abstract: Self-righting articles, such as self-righting capsules for administration to a subject, are generally provided. In some embodiments, the self-righting article may be configured such that the article may orient itself relative to a surface (e.g., a surface of a tissue of a subject). The self-righting articles described herein may comprise one 5 or more tissue engaging surfaces configured to engage (e.g., interface with, inject into, anchor) with a surface (e.g., a surface of a tissue of a subject). In some embodiments, the self-righting article may have a particular shape and/or distribution of density (or mass) which, for example, enables the self-righting behavior of the article. In certain embodiments, the self-righting article a tissuel0 interfacing components. In some embodiments, each tissue-interfacing component may comprise an electrically-conductive portion configured for electrical communication with tissue and an insulative portion configured to not be in electrical communication with tissue.

Abstract: Articles for rapid release of components including, for example, quick release capsules, are generally provided. Advantageously, in some embodiments, the articles described herein may be configured to prevent fluid from contacting a component h contained therein (e.g., tissue interfacing component) or payload contained therein until a desired time, e.g., the time at which the component is configured to release from the article to a location internal to a subject (e.g., localize to a tissue wall in the subject). In some embodiments, the article comprises a first compartment and a second compartment not in fluid communication with the first compartment. In some embodiments, the first compartment and second compartment are fluidically isolated. For example, in some cases, the first compartment comprises a mechanism for releasing a component contained within the article and the second compartment comprises the component.
