  • Patent number: 8047206
    Abstract: Magnetic structures develop a magnetic force between a tongue and a posterior pharyngeal wall to stabilize an orientation of the tongue. The magnetic structures include magnetic materials that are sized, configured, and arranged on at least one of the first and second magnetic structures, to maintain a substantially mutually repelling orientation between the first and second magnetic structures during a native range of movement of the tongue relative to the pharyngeal wall, i.e., during swallowing and/or drinking/and or speech.

  • Publication number: 20100309657
    Abstract: The present invention combines a USB memory device with flashlight to conveniently illuminate a computer USB port for easier insertion of the USB plug. The flashlight can be used independently from the USB memory device to illuminate any dark area. The light is integrated with the USB flash drive, battery powered, bright and focused through a housing which directs the light beam to the front end of the device. The assembly contains a printed circuit board (PCB) including LED bulbs which indicate operational status. The embodiment of the invention includes a removable cap that protects the USB plug and also has a feature which permits the light to pass through for flashlight use. The components are designed in a manner that utilizes physical features to interlock and contain the assembly.

  • Patent number: 7721740
    Abstract: Systems and methods include magnetic structures for placement in or on tissues in an airway. The magnetic structures carry sources of magnetism, which generate magnetic fields having directions. The magnetic fields interact to provide magnetic forces that provide a desired therapeutic effect, e.g., maintaining separation between the soft palate and/or tongue and the posterior pharyngeal wall. The systems and methods size and configure the directions of the magnetic fields to provide stability, which makes possible the achievement of the desired therapeutic effect in a straightforward and elegant manner.

  • Publication number: 20070209665
    Abstract: A magnetic force system uses a magnetic implant sized and configured to be inserted in the pharynx and another magnetic implant sized and configured to be inserted in the tongue, palate, or pharynx. The system establishes different regions of magnetic interaction between the two implants across the airway, attracting and repelling, such that attractive interaction in one region of the implants combines with repelling interaction in another region of the implants, to provide a “hinge” structure. Alternatively, a magnetic force system that uses three magnetic implants sized and configured to be inserted in the tongue, pharynx, and palate, respectively. The tongue implant is attracted to the palatal implant, and repels the pharyngeal implant, forming a modified “hinge” structure. Forces of magnetic attracting bring tissue together to form a magnetic hinge joint, providing an anchor to stabilize the regions where repelling forces work to separate tissue to keep the airway open.

  • Publication number: 20060289014
    Abstract: Systems and methods place a magnetic structure in or on a single tissue mass in an airway. A first magnetic region on a given structure magnetically interacts with a second magnetic region on the structure to shape the structure within the single tissue mass and thereby stabilize a desired orientation for the single tissue mass. The first magnetic region can magnetically interact with the second magnetic region, e.g., by generating magnetic attracting forces.

  • Publication number: 20040237370
    Abstract: A kit is provided for a pendant like award that assembles into an attractive display. It comprises the plaque-like member having peripheral edges on the front side with decorative materials, adhesives, and a location for event information, a predetermined cavity on back side having a counter bore rim with sides and bottom edge, a clearance cut on the top interior edge of the cavity and a fastener hole near each corner. A felt pad is positioned near each backside corner of the plaque-like member to protect other surfaces. Also a predetermined cover plate having a notch for means of either affixation to a wall surface, or used as an attachment of a leg for free standing. Fasteners are positioned through counter sunk holes in the cover plate into the plaque-like member in order to attach the cover plate. Once assembled, the invention provides a specific space where the ribbon can be stored.
