Patent number: 11357452Abstract: A method of determining signal quality in a patient monitoring device includes acquiring one or more signals using the patient monitoring device. One or more signal quality metrics are determined based on the one or more acquired signals. A noise condition is detected based on the one or more signal quality metrics, and a determination is made whether the noise condition should be classified as intermittent or persistent. One or more actions are taken based on the classification of detected noise as intermittent or persistent.Type: GrantFiled: July 24, 2018Date of Patent: June 14, 2022Assignee: Medtronic Monitoring, Inc.Inventors: Niranjan Chakravarthy, Scott Williams, Arthur Lai, Brion C.

Patent number: 9451897Abstract: In one configuration, an adherent device to adhere to a skin of a subject includes a stretchable base layer having an upper side and a lower side and an adhesive coating on the lower side to adhere the base layer to the skin of the subject. The base layer has at least two openings extending therethrough, each of the at least two openings having a size. The adherent device also includes a stretchable covering layer positioned above and adhered to the base layer with an adhesive to define at least two pockets. The adherent device also includes at least two gels, each gel having a size larger than the size of openings to retain the gel substantially within the pocket, and a circuit carrier supported with the stretchable base layer to measure at least one physiologic signal of the subject. Other configurations and methods are also claimed.Type: GrantFiled: December 2, 2010Date of Patent: September 27, 2016Assignee: Medtronic Monitoring, Inc.Inventors: Scott T.
