  • Publication number: 20200080073
    Abstract: An electroporation apparatus and its novel chamber with inlet ports for mixing cells and exogenous material. The inlet ports are oriented in nonparallel to each other immediately adjacent at the same top comer of the first wall of the chamber. The mixing chamber comprises successive wall sections, two curved walls at its bottom; the first curved comer is on the same side of the chamber where the liquids enter the chamber, and directs the liquids to the second curved comer at the opposing side of the chamber, which in turn further redirects the mixing to the first curved corner. The direction of the liquid flow mixture change direction at least twice into the mixing chamber.

  • Publication number: 20190290439
    Abstract: Subchondral bone analog materials and osteochondral constructs that incorporate the subchondral bone analogs are described. The subchondral bone analog materials include a biodegradable matrix, calcium phosphate particles (e.g., hydroxy apatite) and bioactive glass particles. The materials can exhibit sufficient mechanical strength and biochemical properties such that the materials can support boney integration and healing. Osteochondral constructs can include a first layer of the subchondral bone analog material, a second layer of a calcified cartilage analog material, and a third layer of a cartilage analog material.

  • Patent number: 8498935
    Abstract: A system and method for automated adjustment processing using pre-configured sets of business rules is provided. The seller pre-configures a set of business rules for use in processing an adjustment for a specific buyer. The set of business rules may be variable for each buyer and/or globally set. When a payment is received from a seller and an adjustment is required, an adjustment management application retrieves the buyer's set of business rules from the seller. The set of business rules are then applied to attempt to match the received payment to one of the buyer's outstanding invoices. If the match is successful, the buyer's payment is processed.

  • Patent number: 6911902
    Abstract: A tire inflation gas telemetry system (30) is installed inside a tire (174) mounted to a wheel (170) and is placed within a protective housing (100) having pneumatic cylinders (116, 126) with piston rods (128, 130) that are extended or retracted by tire inflation gas pressure changes. The housing is suspended by a cable (156) slung around the wheel. The cable is slack or taut depending on motion of a first piston rod, and the telemetry system is pivoted into alternate protected and operational orientations by motion of a second piston rod. When the tire is uninflated, the cable is slack, and the telemetry system is pivoted into the protected orientation. As the tire is inflated, the cable becomes taut causing the housing to be drawn tightly against the wheel, and the telemetry system is pivoted into the operational orientation.

  • Patent number: 6025777
    Abstract: A tire pressure and temperature measurement system adapts a Y-block (30) to an existing valve stem (20). One branch (44) of the Y-block accepts a conventional valve core (42) and another branch (38) accepts a flexible tubular temperature sensor (36) that leads "down the throat" of the existing valve stem and into the interior of a tire (14, 18). Another embodiment is adapted for use on inside dual tires (18). Making a measurement entails attaching a pressure sensor (40) to the valve stem and attaching a hand-held processor (112) to the sensors. The hand-held processor reads the current tire pressure and temperature; executes a program (Eqs. 1-6) that accounts for measured and target temperatures, vapor pressures, and gas compressibility; and indicates how much pressure to add or subtract to the tire to achieve an accurate final tire operating pressure.
