  • Integrin-Specific Surfaces for Enhanced Tissue Repair (OTL# 3967)
    Inventors: Andrés García, Catherine Reyes, Timothy Petrie, Zvi Schwartz, and Barbara Boyan

    The invention deals with the engineering of biological protein ligands that recapitulate the structure of natural proteins and convey integrin receptor specificity. Binding of specific integrin receptors triggers selective signaling pathways and elicits particular cellular and host responses. An important feature of these biomimetic ligands is that they can be simply applied as bioactive coatings on biomedical devices. These bioactive coatings elicit enhanced healing responses in vivo compared to the unmodified material. Notably, the biomimetic ligand coatings result in improved healing compared to the natural biological protein. Our study establishes a simple, single-step biologically active implant coating that enhances bone repair and implant integration for clinical orthopaedic and dental applications. This strategy may also be applicable for other biomedical and biotechnological applications.

    Applications and Advantages:

    This technology is suited for biomedical and biotechnological applications. Advantages of the technology include:
    • Effective coating technology promoting tissue healing.
    • Simple, one-step surface modification of biomedical devices without chemical cross-linking agents.
    • Modification at the time of surgery in the operation room.
    • Sterilization is straight forward.
    • Ligands are not derived from mammalian sources - minimal risk of pathogen transmission.
    Technology has been demonstrated in cellular and animal (osseointegration) laboratory models. We are currently examining other applications of this technology.

  • Composite Morphing Wing (OTL# 3952)
    Inventors: Samer Tawfik and Erian Armanios

    The morphing wing concept uses laminated composites allowing for the efficient creation of a Hyper-Elliptic Cambered Span as well as winglet type wings. Actuating the wing to move between possible configurations makes it extremely adaptable to different flight missions and maneuvers.

    Applications and Advantages:
    • Simplified design by eliminating control surfaces
    • Achievement of wings for multi-mission flight envelopes
    • Low energy required for actuation
    • Longer fatigue life

  • System for Easy Installation and Configuration of Networked Devices(OTL# 3698)
    Inventors: Warren Keith Edwards and Jeonghwa Yang

    Configuring devices to work on a network is a time-consuming and error-prone chore. This invention is allows much easier installation and configuration of devices on a network, and also provides the ability to centrally reconfigure devices based on changes in network topology. Our system provides functionality—which can be built into a router, standalone PC, or other device—that allows new devices to be correctly configured in seconds, setting up network parameters as well as application shortcuts, file shares, default printers, and so forth.

    Applications and Advantages:

    This technology is suited for both enterprise and home network applications. Advantages of the technology include:
    • In the enterprise:
      1. Lower IT costs through easier network configuration
      2. Enforce secure access to network
      3. Provide mechanisms for easier overall network evolution and upgrade
    • In the home:
      1. Reduce service calls, by allowing homeowners to correctly configure their devices themselves
      2. Eliminate security holes, such as open WiFi networks
      3. Reduce the overall complexity of home network management

    State of Development:
    Prototypes of this technology have been demonstrated at the Georgia Tech GVU Center. The core implementation has been completed, and work is proceeding on further refinements.

    A provisional patent application has been filed.

  • Miniature Combustion-Driven Machine (ID# 1949)
    Inventors: Dr. Ari Glezer & Dr. Mark Allen

    This invention concerns a micro heat engine for electrical and mechanical power generation. This approach to micro heat engines is unique in the sense that it is driven by a periodic combustion process, and it is implemented using micromachining technology. In the application of mechanical power generation, the mechanical and electrical functionality of the engine is highly integrated; it performs both the fuel-to-mechanical energy conversion as well as the mechanical-to-electrical energy conversion. The machinery is constructed using very few moving parts.

    This invention is portable, has low heat release and low fuel consumption, low acoustic emissions and low combustion emissions. It is expected that the technology can be used for miniature power generation, miniature actuators, miniature compressors, vacuum pumps, battery chargers, and can also be applied to UAV technology.

    This invention is protected under US Patent number 6,109,222.
