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.

Abstract: A surgical rongeur device has an interchangeable, locking tip at a cutting end for engageable replacement with a variety of cutting tips for facilitating sterilization and blade changes. A detachable linkage between a handle portion and an interchangeable cutting tip (tip) provides a strong connection for actuation by the handle end but allowing for tip replacement via slidable, lateral displacement of the tip. The tip includes a blade and footplate formed from an amorphous metal for longevity and strength advantages. A handle provides a lever to actuate the tip from slidable communication via the detachable linkage. An interlocking member extends longitudinally from the handle into an internal slot on the tip for locking the tip by preventing lateral movement out of alignment with the handle. The aligned tip is responsive to actuation from the handle via a rail for disposing the blade longitudinally against the footplate.

Abstract: Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.

Abstract: A fiber optic based particle manipulation system employs one or more optical fibers for emanating a refracted optical manipulation signal directed at a target particle for fixing or manipulating the particle for examination, research and manufacturing. A target particle may be a living cell or inanimate sample or compound of matter. An alignment linkage controls optical fibers carrying the manipulation signal for focusing one or more manipulation signals on the target particle. Manipulated particles occupy a fluid medium of either liquid or gas, and are responsive to the manipulation signal based on both photon bombardment and temperature differential from photon contact. The temperature differential is based on surface properties of the target particle, as smooth particles tend to exhibit a greater thermal differential for stronger displacement forces driving or affecting the target particle.

Abstract: Magneto-responsive properties are traditionally imparted to scaffold systems via integration of iron oxide-based magnetic nanoparticles (MNPs), yet poor understanding of long-term MNP toxicity presents a significant translational challenge. Given the demonstrated iron-binding capacity of silk fibroin (SF), passive chelation of ferric iron ions is explored herein as an alternative, MNP-free approach for magnetic functionalization of silk fibroin (SF)-based biomaterials. SF microfibers treated with aqueous ferric chloride (FeCl3) exhibit significantly increased iron content relative to the nascent protein.

Abstract: A security assessment tool and application for an autonomous robotic systems utilizes a Bayesian Network for scoring each subsystem based on security-enabled features. Each subsystem layer may consist of the system, hardware, software, Al, and supplier elements in an autonomous robotic (or other) system. Each element is assessed on the basis of its trustworthiness (based on factors such as the integrity of the design process, the engineering process, followed by the assessment of the integrity of the supplier, and the like) as well as a weighting based on the criticality of that element to the correct operation of the system. Using these factors, a “belief’ in the assurance of the system is determined based on a Bayesian model. The Bayesian Network is used to determine an autonomous robotic systems' internal trust before that can be extended to an external entity.

Abstract: A method for recycling secondary battery charge materials includes a one-step molten-salt process to upcycle mixed Ni-lean polycrystalline NMC cathodes into Ni-rich single-crystal NMC cathodes. The method includes receiving a recycling stream of charge materials from end-of-lifetime batteries, adding additional charge materials based on an upcycled battery chemistry intended for the upgraded, recycled battery, and sintering the combined charge materials for generating a single crystal charge material corresponding to the upcycled battery chemistry using a molten salt direct recycling process.

Abstract: A rechargeable lithium-ion (Li-ion) battery employs a low temperature approach to battery manufacturing that forms charge material from kinetic energy of high velocity particles impelled into an aggregation such that bombardment of the particles against other particles in the aggregation forms a charge conveying structure. High velocity bombardment from a carrier gas nozzle accumulates an active charge material in a layered arrangement for the finished battery. Preparation of the particles, such as by ball milling or spraydrying, arranges particle agglomerations. The particle agglomerations, when impelled against other agglomerations or a current collector, forms a layer of cathodic, anodic or electrolytic battery material. The metallic binder conveys charge for mitigating or eliminating a need for a planar current collector underlying the sprayed layer. The resulting layers are suitable for battery operation, and are manufactured in an absence of any solvent drying or disposal.
