Abstract: A wound care treatment platform and application employs a mobile device and application (“app”) for on-site capture and gathering of wound images from a patient. The mobile device is in wireless communication with a database including health records and data and trained models of wound image classification. Based on a patient image of a wound under care, the image is analyzed for features indicative of wound health and healing progress. The mobile device invokes a plurality of models for providing an accurate and consistent assessment and treatment recommendation, including evaluating the sufficiency of the patient image gathered by the mobile device, normalizing the patient image for adverse or irregular lighting, common in patient dwellings, adjusting for a distance and angle at which the caretaker obtained the image, computing a comprehensive score of wound healing, and rendering an evaluation for referral or continuance of current outpatient care.

Abstract: Production of high purity iron powder employs high efficiency low temperature electrolysis resulting in a process requiring substantially less energy with no CO2 gas and has high energy reduction. Configurations provide a renewable electricity supply that is environmental benign with low energy consumption. A hematite (Fe2O3), carbon and highly concentrated NaOH combine to form an electronically and ionically conductive suspension for iron production. The suspension is flowable which can also be applied to a flow electrolysis system. High purity iron powder is produced at the cathode side while the anode side can produce O2 gas as a byproduct.

Abstract: A Metaverse Laboratory (ML) is a self-contained comprehensive research and development (R&D) laboratory facility for hybrid modeling and simulation, conceptual and engineering design, prototyping, and experimentation in an operational environment (real, virtual, or augmented) by analyzing consequences based on simulated or actual (live) inputs from either human actors and/or predetermined scenarios. A physical facility encloses a rendering area configured to receive projected images and physical devices or objects. User interaction may be accompanied by image rendering goggles in conjunction with physical interactions with vehicles, objects and/or other users disposed in the rendering area. Computing equipment for driving a rendered scenario directs the outputs including visual and tactile feedback according to the scenario, and input from sensors and users in the rendering area determines a computed response. The collective facility provides a generalized environment for programmed realities for modeling and simulation combined with tangible objects, devices and human actors.

Abstract: A recycling process for exhausted, end-of-life solar panels achieves substantial recovery of silicon and silver, as well as other materials, from a recycling stream of discarded solar panels. Agitation and shredding of the solar panels yield a granular mass, which can be separated by particle size to yield the silicon rich solar cell material. Leaching with a strong base such as sodium hydroxide draws the silicon into the leach solution. Filtration of the leach solution draws off the silicon-rich solution and allows filtration of other valuable materials such as silver. Addition of an acid such as hydrochloric acid to the leach solution then precipitates the silicon into a nano silica powder of in the form of high purity silicon dioxide. The high purity silicon dioxide provides raw materials for recycled solar panels, lithium-ion batteries and other uses depending on the purity.

Abstract: An atomizing spray dryer employs one or more stages defined by ultrasonic transducers in close proximity to a liquid feed opening forming a path of an atomization flow for producing uniform droplets from a close tolerance with the transducer. The atomization flow exits a gap between the transducer and an outer edge of the opening, such that the passed liquid is responsive to an oscillation of the transducer for forming the droplets. A conical or other suitably shaped transducer engages a substantially round liquid feed opening. Subsequent stages may include a circular, ring, or other suitable shape aligned to receive the atomization flow from a circumference of the conical base, or may also take any suitable shape, preferably to receive droplets directed by the first stage.

Abstract: Embodiments of the present innovation relate to a Fourier dot product analog matrix multiplier device. In one arrangement, the analog matrix multiplier device is configured as a set of analog transistor circuits and can include a set of signal generators and a Fourier dot product circuit. The components of the analog matrix multiplier device are configured to perform a Fourier dot product multiplication process relative to coefficients received by the analog matrix multiplier device. The Fourier dot product analog matrix multiplier device leverages the low power capabilities of analog circuits and a mathematical algorithm to reduce the number of components and power required to perform matrix multiplication.

Abstract: A recycling and waste management process receives municipal solid waste (MSW) with substantial organic content to form a self-sustaining Hydrothermal Mineralization (HTM) process based on Supercritical Water Oxidation (SCWO) to receive supercritical steam and carbon dioxide with potential for electrical generation before forming calcium carbonate suitable for concrete production. Hydrothermal mineralization (HTM) provides a rapid elimination of organic wastes while simultaneously producing a non-emissive and thermally stable cement additive to act as a carbon sink. Hydrothermal mineralization (HTM) provides a rapid disposal pathway for organic wastes, a green source of electricity and a final product that can be coupled with traditional and alternative cement productions to reduce carbon footprints of cement production.

Abstract: Mammalian cell production systems are disclosed herein wherein a living mammalian cell culture including a mammalian growth medium operative is co-cultured with a living algae cell culture including an algae growth medium operative to feed nutrients and carbon dioxide to a plurality of algae cells and to transport an algae waste from the plurality of algae cells. The living algae cell culture produces an algae waste with one or more nutrients and oxygen operative to feed the mammalian cell culture, while the living mammalian cell culture produces a mammalian waste with one or more nutrients and carbon dioxide operative to feed the algae cell culture. The systems are capable of a continuous operation at normal mammalian temperature and pH, thereby removing a need to cool down the algae growth medium and/or heat up the algae growth medium for a treatment of algae or for a replenishment of algae.

Abstract: An endoscopic system may include an endoscope including a handle and an elongate shaft extending distally therefrom. The handle may include a non-motorized and non-ratcheting actuation mechanism configured to articulate a distal tip portion of the elongate shaft. The distal tip portion may be articulatable in response to a manually applied force exerted upon the actuation mechanism. Removal of the manually applied force may lock the distal tip portion in its then-current configuration. The non-motorized and non-ratcheting actuation mechanism may include a clutch mechanism actuatable in response to an electrical signal generated in response to sensing a user-applied force to the actuating mechanism by a strain gauge.
