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: A health experience detection system comprises an eye-tracking device and a health experience detection device disposed in electrical communication with the eye-tracking device. The health experience detection device comprises a controller having a memory and a processor. The controller is configured to: receive eye-movement data from the eye-tracking device, the eye-movement data associated with eye-movement of a user and comprising at least one of saccade event data and fixation event data, apply the eye-movement data to a health experience identification engine to generate a health experience identifier associated with the user, and output a notification regarding the health experience identifier of the user as associated with the eye-movement data.

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: 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 purification process for recycled graphite for use as anode material in Li-ion batteries includes a sequence of leaching and heat treatment followed by washing with deionized (DI) water and an acid wash. A graphite source results from a suitable process such as acid leaching of black mass from a battery recycling stream, where the leach removes a substantial portion of metal salts used for cathode materials. Impurities, most notably aluminum oxide and residual cathode materials, are often present in trace amounts in the graphite source. A sequence of heating (sintering) and pH adjusted washing further purifies the graphite into a modified, recycled graphite exceeding 99.5% purity for use in a recycled battery.

Abstract: Bauxite residue recovery includes mixing a solution of hydrochloric acid (HCL) according to a predetermined concentration, and adding the HCL solution to a quantity of raw red mud recovered from industrial operations as waste material. The highly alkaline property of the bauxite residue, commonly known as red mud is at least partially neutralized from the HCL, and makes the resulting washed red mud more amenable to subsequent uses in various applications in fields such as construction, wastewater treatment, and metal recovery processes. The process recovers washed red mud from the red mud and HCL solution by filtering the raw red mud and HCL solution for generating a stream of leach liquor from the filtrate and the recovered washed red mud from the residue.

Abstract: A nozzle apparatus for a 3D printer employs a center post or shape and extrudes a circumferential, tubular form having a central void. The nozzle includes a radial arrangement of prongs or supports around a center post, which provides space for molten print medium to flow in a 360° form around the center post. The nozzle extrudes a hollow tubular form around the post that can lay a tube shaped article on a perpendicular print bed, or can be used to deposit high resolution, hollow cylindrical segments for forming lightweight articles with less volume of print medium required due to the hollow extruded shape. A stream of air or gas may be emitted into the center of the extrusion for maintaining a tubular shape. Other suitable shapes may be employed by altering the contour of the center post and the bore.

Abstract: Actuators and methods of use are provided. An actuator may include an inner member made from an elastic material and defining a compartment for receiving an actuating fluid, the inner member being moveable in a longitudinal direction from a relaxed state to an expanded state by introducing an actuating fluid into the inner member; and an outer member made from an inelastic material and being disposed around the elastic inner member to control expansion of the elastic inner member in a radial direction, the outer member being moveable from a folded relaxed configuration to an unfolded extended configuration as the inner member moves from the relaxed state to the expanded state, wherein the movement of the actuator between the relaxed state and the expanded state causes a movement of a structure to which the actuator is attached.
