  • Patent number: 11357452
    Abstract: 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.

  • Patent number: 9451897
    Abstract: 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.

  • Patent number: 9084583
    Abstract: Methods and devices for monitoring and/or treating patients comprise a switch to automatically start-up the device when the device contacts tissue. By automatically starting up the device, the device may be installed without the clinician and/or user turning on the device, such that the device can be easy to use. In many embodiments, the device comprises startup circuitry with very low current and/or power consumption, for example less than 100 pA. The startup circuitry can detect tissue contact and turn on circuitry that is used to monitor or treat the patient.
