  • RFID near field microstrip antenna
    Patent number: 7791540
    Abstract: A near field antenna is disclosed which is configured to read an RFID label such that a localized electric E field emitted by the antenna at an operating wavelength resides substantially within a zone defined by the near field. The localized E field directs a current distribution along an effective length of the antenna corresponding to a half-wave to a full-wave structure.
    Type: Grant

  • Intraoral endotracheal tube holder and method for intubation
    Patent number: 7063088
    Abstract: A tube holder assembly and method for securing an endotracheal tube to a biteline of a patient's mouth. The tube holder assembly features a tube body. A bite support assembly, coupled to the tube body, receives a tensile force and supplies a compressive force to the mouth of the patient. The bite support assembly includes a pair of substantially parallel bite walls extending outwardly from the exterior surface of the tube body. The bite walls define a bite rest therebetween for receiving a biteline of the patient's mouth and thus securing the biteline between a pair of bite walls as the bite rest applies a compressive force to the biteline.
