Patent number: 7331343Abstract: Methods and systems for supplying supplemental oxygen to patients for use in sub-acute care which maintains healthy blood oxygen content in the patients by controlled dosing of oxygen with a measured response to the patient's actual blood oxygen content are disclosed. The dosing can be provided by simple ON/OFF control over the delivery of oxygen or the amount of oxygen delivered to the patient with each inhalation can be varied in response to the patient's need as determined by a more sophisticated control scheme, such as a PID loop control algorithm, that utilizes the difference between the patient's actual blood oxygen content and a target blood oxygen content and/or trends in the blood oxygen content. The systems and methods are particularly directed at patients receiving supplemental oxygen in a sub-acute care environment.Type: GrantFiled: February 20, 2003Date of Patent: February 19, 2008Assignee: Minnesota Innovative Technologies & Instruments Corporation (MITI)Inventors: Matthew F. Schmidt, John S. Buan, Catherine A. Nordman

Publication number: 20060213519Abstract: Methods and systems for supplying respiratory oxygen to users when the users are inhaling are disclosed. The methods and systems may rely on delivery devices that are selectively placed in fluid communication with either a respiration sensor or a source of oxygen. The methods and systems may actively monitor for exhalations, as well as monitor for oxygen in the oxygen source. The respiration sensor may preferably be a flow sensor.Type: ApplicationFiled: May 26, 2006Publication date: September 28, 2006Applicant: Minnesota Innovative Technologies and InstrumentsInventors: Matthew Schmidt, John Buan, Catherine Nordman

Patent number: 7054114Abstract: A ferromagnetic thin-film based magnetic field sensor with first and second sensitive direction sensing structures each having a nonmagnetic intermediate layer with two major surfaces on opposite sides thereof having a magnetization reference layer on one and an anisotropic ferromagnetic material sensing layer on the other having a length in a selected length direction and a smaller width perpendicular thereto and parallel to the relatively fixed magnetization direction. The relatively fixed magnetization direction of said magnetization reference layer in each is oriented in substantially parallel to the substrate but substantially perpendicular to that of the other. An annealing process is used to form the desired magnetization directions.Type: GrantFiled: November 17, 2003Date of Patent: May 30, 2006Assignee: NVE CorporationInventors: Albrecht Jander, Catherine A. Nordman, Zhenghong Qian, Carl H. Smith
