    Abstract: A non-invasive method of detecting anomalous tissue, such as cancerous or injured tissue, in a patient. At least two hemoglobin signal components of hemoglobin levels in at least one segment of tissue of the patient are non-invasively measured over time. Time varying changes of at least a first of the hemoglobin signal components are measured with respect to at least time varying changes of a second of the hemoglobin signal components. A co-varying coordinate system of the time varying changes is generated. Any anomalous tissue in the measured segment of tissue is detected from a signature of the measured segment of tissue in the co-varying coordinate system which differs from a signature of non-anomalous tissue in the co-varying coordinate system. Preferably, five hemoglobin signal components are measured: oxyHb, deoxyHb, total Hb (totalHb=oxyHb+deoxy Hb), Hb oxygen saturation (HbO2Sat=(oxyHb/totalHb)*100), and tissue-hemoglobin oxygen exchange HbO2Exc (deoxyHb?oxyHb).

  • Patent number: 11065442
    Abstract: An implantable electrical stimulating device and system provides for a remote determination of the identity of the person in whom the stimulating device is implanted. The stimulating device may be a pacemaker, a defibrillator, another medical device or a non-medical device. The bases for the remote identification are (1) the comingling of (A) biologic identification information of the person linked to the stimulating device, and (B) information pertaining to a physiologic parameter (e.g. heart rate information) of that person, and (2) the modulation of the physiologic parameter by external information. Embodiments of the invention in which the stimulating device is external to the person are possible. By utilizing the apparatus providing for the remote identification of a person plus stimulating device, one aspect of secure communication—that based on reliable mutual identification of each participant in a communication—is achieved.

  • Patent number: 11058360
    Abstract: It is possible to measure a pulse rate correctly, when a body moves. A frequency analysis unit 13 generates a pulse wave frequency signal by converting pulse wave detection signals detected by a light sensor 20 into a frequency domain signal from time domain signals. A body motion level determination unit 14 determines a body motion level of a subject based on acceleration detection signals output by an accelerometer 21. A peak detection unit 15 detects a peak of spectrum intensity in the pulse wave frequency signal within a peak searching range, which varies depending on the determined body motion level. A pulse calculation processing unit 16 generates pulse information based on a frequency position of the peak detected by the peak detection unit 15.

  • Patent number: 11051760
    Abstract: The present invention relates to a wearable device for healthcare and method for using the device. More specifically, the wearable device is worn on a finger for measuring the health data of the user, selected from one or more of heart rate, blood oxygen saturation, heart rate variability. Based on the measured data, the sleep quality can be monitored and recorded. Disorders such as obstructive sleep apnea (OSA), can be detected. The wearable device may include an optical sensor coupled with or embedded in a main body including a visible light emitter, an IR light emitter and a light detector being arranged along a longitudinal direction of the finger. During operation of the wearable device, the heart rate is monitored based on a detected light signal. When the heart rate is higher than an adaptive threshold, both heart rate and blood oxygen saturation are monitored.

  • Patent number: 11033241
    Abstract: Pulse oximeter systems are described that detect an oxygen level of a user and/or monitor a user's heart rate. The pulse oximeter systems are configured to provide an alert when a user's detected oxygen level decreases below an established oxygen level, and/or when a user's heart rate decreases below a lower threshold value and/or increases above an upper threshold value. For example, an alert may be provided when a user's detected oxygen level decreases by more than about five percent (5%) of an established oxygen level. In some instances, an operator can set a level at which an alert will be provided.
