Patent number: 11926810Abstract: A bioreactor includes a reservoir container for holding a liquid medium, a duct providing a flowpath in a generally vertical direction upward from the reservoir container, a plurality of fiber assemblies located within the duct, a top of which is higher than a top of the plurality of fiber assemblies, and a circulation system. The upper end of the duct comprises an overflow wall surrounded by a moat, a bottom of which is lower than a top of the overflow wall. The upper end of the duct and moat contact a pocket region that is bounded by a structure that is connected to the duct and that is isolated from fluid communication with an exterior of the pocket region. The liquid medium flows over the overflow wall within the pocket region, contacts gas in the pocket region, overflows into the moat and is removed therefrom by the circulation system.Type: GrantFiled: December 6, 2022Date of Patent: March 12, 2024Assignee: 3D Biotek, LLCInventors: Zongsen Wang, Wing Lau, Faribourz Payvandi, Peng Yue, Azadeh Jadali, Peter Materna

Patent number: 11916508Abstract: An Underground Pumped Hydro Storage system may comprise a substrate, a large water-fillable bag, and an overburden causing pressure in the bag. The overburden may have nonuniformities of composition or dimension. Such nonuniformities may locally make overburden more flowable or gentle to the bag, at regions of relatively high shape change or flow during a cycle. Such nonuniformities may help prevent the overburden from freezing up in cold weather, or may enable a controlled progression of bag shapes. The overburden may have an irrigation hose buried in it. The bag edge joint may have any of various features that provide for a transition of local bending and load distribution near the joint between the bag upper and lower layers. An antechamber may be provided for access to the bag interior for robotic inspection or maintenance. The system may be deployed near a dam on a river.Type: GrantFiled: December 16, 2021Date of Patent: February 27, 2024Inventors: Peter A Materna, Ralph L Hensler

Patent number: 11218109Abstract: An energy or water storage system can comprise a storage reservoir, a discharge reservoir, a pump for charging the storage reservoir, and a turbine or similar discharge device. The storage reservoir can comprise a flexible bag covered by overburden that creates pressure inside the bag. Energy is stored by raising the overburden. The bag can comprise a shaped internal filler piece to prevent formation of a crease at the bag edge. Solar panels can be mounted above any bag to make additional use of the land. Solar panels mounted on overburden can have tracking mechanisms and controls suitable to achieve desired orientation regardless of the slope of overburden. Elevation difference between the storage reservoir and discharge reservoir can be used, including an underground cavity. The bag can have internal tethers to influence bag shape.Type: GrantFiled: July 6, 2020Date of Patent: January 4, 2022Inventor: Peter A Materna

Publication number: 20210381131Abstract: Disclosed are hollow fibers suitable for use in dialysis in an outside-in configuration. For such fibers, it is desirable that the fiber have a low albumin sieving coefficient and have a permeability high enough to be considered a High Flux dialyzer, and it is desirable that the outer (blood-facing) surface have a sufficiently small roughness and be hydrophilic. It is desirable that there be a selective layer on the outer surface and, interiorly of that, a porous structurally supportive region, which may contain elongated macrovoids. Such a fiber may be spun through a triple-concentric spinneret that produces a bore liquid surrounded by dope surrounded by a shower. The shower and the coagulation bath may be pure water, which is a non-solvent. The process may be performed at room temperature. Spinning parameters are discussed.Type: ApplicationFiled: June 4, 2021Publication date: December 9, 2021Inventors: Ilaria Geremia, Dimitrios Stamatialis, Mohamed Labib, Peter Materna Materna

Patent number: 10918497Abstract: An implantable medical device, such as an intervertebral spacer, may comprise a polymeric component and a metallic component. The metallic component can contain both porous metal and substantially-solid metal. The polymeric material can contain particles of an osseointegrative material. The metallic component can be more protruding toward bone than the polymeric component while having a smaller dimension of roughness than the polymeric component. In embodiments, the pin may press-fit against substantially solid metal. The porous metal may surround solid metal which in turn may surround the pin. The pin may have a press-fit with metal and a looser fit with polymeric component, if the metal components and polymeric components are trapped. A pin may connect superior and inferior metal components by a press-fit. The central opening may be exposed to porous metal and also to substantially-solid metal and to polymer. Specific geometries of implants are disclosed.Type: GrantFiled: October 24, 2018Date of Patent: February 16, 2021Assignee: Omnia Medical, LLCInventors: Troy Schifano, Daniel Johnson, Stephen Anderson, Peter Materna
