  • Patent number: 11896234
    Abstract: Described herein are the use of fluid complex coacervates that produce solid adhesives in situ to anchor medical devices such as catheters in a blood vessel. The anchored devices permit the targeted delivery of bioactive agents. The anchored devices can perform as an embolic agent by reducing or preventing blood flow in the vessel. Additionally, the embolic produced from the solid adhesive produced in situ can also include one or more bioactive agents that can be released in a controlled manner.

  • Publication number: 20230068528
    Abstract: The present disclosure provides systems and methods for animal health monitoring. Load data can be obtained from an animal monitoring device including three or more load sensors associated with a platform carrying contained litter thereabove, wherein individual load sensors of the three or more load sensors are separated from one another and receive pressure input from the platform independent of one another, wherein the three or more load sensors individually sample loads at from 2.5 Hz to 110 Hz. An animal behavior property associated with the animal can be recognized if it is determined based on load data that the interaction with the contained litter was due to the animal interaction with the contained litter. The animal behavior property can be classified into an animal classified event using a machine learning classifier.

  • Publication number: 20230061071
    Abstract: The present disclosure provides systems and methods for animal health monitoring. Load data can be obtained from a plurality of load sensors associated with a platform carrying contained litter thereabove, wherein individual load sensors of the plurality of load sensors are separated from one another and receive pressure input from the platform independent of one another. If the load data is determined or not to be from an animal interaction with the contained litter, an animal behavior property associated with an animal is recognized if a determination is made based on load data that the interaction with the contained litter was due to the animal interaction. The animal behavior property is classified into an animal classified event using a machine learning classifier. A change in the animal classified event is identified as compared to a previously recorded event associated with the animal.

  • Patent number: 9272069
    Abstract: Described herein is the synthesis of adhesive complex coacervates. The adhesive complex coacervates are composed of a mixture of one or more polycations, one or more polyanions, and one of more multivalent cations. The polycations and polyanions in the adhesice complex coacervate are crosslinked with one another by covalent bonds upon curing. The adhesive complex coacervates have several desirable features when compared to conventional bioadhesives, which are effective in water-based applicatgions. The adhesive complex coacervates described herein exhibit good interfacial tension in water when applied to a substrate (i.e., they spread over the interface rather than being beaded up). Additionally, the ability of the complex coacervate to crosslink intermolecularly increases the cohesive strength of the adhesive complex coacervate. The adhesive complex coacervates have numerous biological applications as bioadhesives and drug delivery devices.

  • Publication number: 20130264531
    Abstract: A panel jack includes a clamp with opposing jaws spaced apart upon a frame or bar, and a jack mounted onto the clamp at the base of the jack, the shaft or piston of the jack attached to an elongated brace. The brace may turn about the longitudinal axis of the jack and the jack may turn about the longitudinal axis of the clamp in order for the device to be folded into either a storage position or operational position. When in use, the longitudinal axis of the brace is perpendicular to the longitudinal axis of the jack and the jack is attached proximate to the center of the brace so that force exerted by the jack upon the brace may be distributed generally evenly along the length of the brace.

  • Patent number: 7179487
    Abstract: A stimuli-responsive, hybrid hydrogel wherein the bulk of the polymer is made up of relatively inexpensive water soluble polymer strands crosslinked by protein domains. The responsiveness of the gel is controlled or modulated by the protein component. The physical and biological properties of the hydrogel are determined by specifically designed or engineered protein domains. The crosslinking of the protein domains to the water soluble polymers is by means of non-covalent bonding such as chelation or coordination bonding, biotin-avidin bonding, protein—protein interaction and protein-ligand interaction, or by means of covalent bonding. Methods of making and using the polymer-protein hydrogels are disclosed in this application.

  • Patent number: 6267626
    Abstract: An electrical connector, for use in conjunction with or forming part of, a thermocouple probe has a body of electrically Insulating material, preferably formed by moulding, a plurality of apertured blocks of ferrite material within the body, and a corresponding plurality of elongate metallic conductors within the body and positioned through and projecting from a respective block of ferrite material. In a preferred form, the metallic conductors are made of metals of different alloy designation, as appropriate to the metal alloys used in the associated thermocouple probe. Further, the metallic conductors are advantageously made of different cross-sectional dimensions and/or different cross-sectional shape, such that the connector may be mated with a corresponding connector in only one manner of plug and socket.

  • Patent number: 6087452
    Abstract: A modified surfactant of the PLURONIC.TM.-type compound and method for manufacture is disclosed. The surfactant compound has at least one PEO block attached at a first end to at least one PPO block, with at least one of the PEO block having an organic metal-chelating end group (R) attached to a second end, the remaining PEO blocks having an unmodified hydroxyl group at the second end. The metal-chelating group is charged with an metal-ion. A protein with a metal-affinity tag, e.g., a histidine tag, is then complexed with the metal-chelating group to form a complex of the modified surfactant, the metal ion, and the protein. The modified surfactant may be adsorbed upon a hydrophobic surface, charged with a metal ion, and then complexed with a protein with a metal-affinity tag. A surface with specific activity toward proteins is the presented, which is suitable for applications where a protein is immobilized upon a surface to give the surface specific protein activity.
