*** Honeywell International Assigned Patent ALEXANDRIA, Va., Oct. 4 -- Honeywell International, Morristown, N.J., has been assigned a patent (8,280,673) developed by Mohammad A. Aljabari, Brooklyn Park, Minn., for a "system for determining ambient temperature." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A mechanism for indicating ambient temperature of an enclosure from temperatures determined within the enclosure. The temperatures may be obtained from two or more sensors at each of two or more locations within the enclosure. The enclosure may include an apparatus inside such as electronics of which power consumption may be determined. Data including temperatures of two locations within the enclosure at various electronics power consumption levels may be entered into a 2-D plot. An approximation of the 2-D plot may be effected with an appropriate equation to be solved for ambient temperature. The data of the dimensional 2-D plot plus temperatures of a third location and air flow levels in the enclosure may be entered into a 3-D plot. An approximation of the 3-D plot may be effected with an appropriate equation to be solved for ambient temperature." The patent application was filed on Dec. 4, 2007 (11/950,394).

*** Medtronic Assigned Patent for System and Method for Unscheduled Wireless Communication with a Medical Device ALEXANDRIA, Va., Oct. 4 -- Medtronic, Minneapolis, has been assigned a patent (8,280,521) developed by six co-inventors for a "system and method for unscheduled wireless communication with a medical device." The co-inventors are Gregory J. Haubrich, Champlin, Minn., Len D. Twetan, Excelsior, Minn., David Peichel, Minneapolis, Charles H. Dudding, Lino Lakes, Minn., George C. Rosar, Minneapolis, and Quentin S. Denzene, Andover, Minn.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Unscheduled wireless communication with a medical device is achieved by operating a receiver of the medical device in a series of modes. Each mode provides an increasingly selective evaluation of received RF energy. The receiver, when operating in a first mode, is capable of detecting the presence of RF energy transmitted from a communicating device. The receiver, when operating in a second mode, consumes more energy than the first mode and analyzes the RF energy to determine whether it contains the appropriate type of modulation. When operating in a third mode, the receiver consumes more energy than the second mode, and operates the full receiver to begin communication with the communicating device. The receiver opens a communication session after the RF energy has passed the evaluation by the series of modes to receive an unscheduled communication." The patent application was filed on Oct. 14, 2011 (13/273,630). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,280,521&OS=8,280,521&RS=8,280,521 Written by Satyaban Rath; edited by Hemanta Panigrahi.

The co-inventors are Dennis M. Skelton, Bloomington, Minn., Emmanuel R. Darne, Woodbury, Minn., Justin Kemp, St. Louis Park, Minn., Nicholas S. Mairs, Minneapolis, and Brian Sorenson, New Brighton, Minn.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Techniques for validating operation of a medical device are disclosed. A data collection phase utilizes a first sensor carried by a patient to record patient parameter values indicative of conditions experienced by the patient (e.g, posture states.) Therapy parameter values describing therapy adjustments requested by the patient in response to the conditions are also recorded. Associations formed between the therapy parameter values and the patient parameter values are used to develop a closed-loop algorithm for control of an IMD having a sensor similar to the first sensor. An automated device such as a robotic arm uses the recorded patient parameter values to automatically reproduce, and to subject the IMD to, conditions present during the data collection phase. Therapy delivered by the IMD while under control of the closed-loop algorithm and while being subjected to the conditions is compared to the recorded therapy parameter values e to validate IMD operation." The patent application was filed on Aug. 26, 2009 (12/548,227). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,280,517&OS=8,280,517&RS=8,280,517 Written by Satyaban Rath; edited by Hemanta Panigrahi.

Spinelli, Lakewood Ranch, Fla., for "identifying heart failure patients suitable for resynchronization therapy using QRS complex width from an intracardiac electrogram." The abstract of the patent published by the U.S. Patent and Trademark Office states: "Methods and systems are disclosed for determining whether a patient is a responder to cardiac resynchronization therapy. The beginning and ending of the intrinsic ventricular depolarization are determined through signals measured from one or more electrodes implanted in the patient's heart. An interval between the beginning and ending of the intrinsic ventricular depolarization is computed and is compared to a threshold. The threshold may be determined empirically. The pacing parameters of a heart stimulation device, such as a pacemaker, may then be configured, for example, by setting the paced atrio-ventricular delay based on whether the patient responds positively to cardiac resynchronization therapy." The patent application was filed on Aug. 5, 2008 (12/221,650). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,280,512&OS=8,280,512&RS=8,280,512 Written by Satyaban Rath; edited by Hemanta Panigrahi.

Sweeney, Woodbury, Minn., for "signal compression based on curvature parameters." The abstract of the patent published by the U.S. Patent and Trademark Office states: "For a sampled signal, storing characteristic points generated based on parameters corresponding to curvature of the signal. The characteristic points include a time of occurrence of a lobe in a curvature series based on the signal and a corresponding amplitude of the signal. The characteristic points provide a compressed version of the sampled signal. The signal is reconstructed by establishing a function between a chronological sequence of characteristic points.

*** MAYO Foundation for Medical Education and Research Assigned Patent ALEXANDRIA, Va., Oct. 4 -- MAYO Foundation for Medical Education and Research, Rochester, Minn., has been assigned a patent (8,280,135) developed by Cynthia H. McCollough, Byron, Minn., and Lifeng Yu, Inver Grove Heights, Minn., for a "system and method for highly attenuating material artifact reduction in x-ray computed tomography." The abstract of the patent published by the U.S. Patent and Trademark Office states: "The present invention is a method for reducing artifacts caused by highly attenuating materials in x-ray computed tomography ("CT") images. The method includes combining projection views acquired at equivalent view angles to generate a projection plane data set, from which a reformatted projection is produced. The reformatted projection is then processed to detect and segment regions corresponding to objects composed of metals, metal alloys, or other highly attenuating materials. These segmented regions are then removed from the reformatted projection and the removed portions replaced by attenuation information interpolated from portions of the reformatted projection adjacent the removed portions. The interpolated reformatted projection is then mapped back to a projection plane data set, and an image of the subject is reconstructed from the projection views contained in that data set. The reconstructed image, therefore, is one in which artifacts caused by highly attenuating materials are substantially suppressed." The patent application was filed on Jan. 20, 2010 (12/690,765). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,280,135&OS=8,280,135&RS=8,280,135 Written by Arpi Sharma; edited by Anand Kumar.
