  • Patent number: 10315037
    Abstract: Devices that communicate using wireless proximal communications measure pulse width to find distortion in the received signal. The distortion may be due to the devices being too close to one another for a transmission power level currently being used which causes ringing of a receiving coil. The distortion may be used to find a correction that the receiving device may use to correct for the distortion in the received pulse train when decoding the pulse train. The distortion may be used to adjust a transmission power level of the receiving device and/or to send an instruction to the transmitting device to adjust the power transmission power level of the transmitting device. The distortion may be used for other purposes including determining a device depth and/or location for an implanted device, such as an implantable medical device within a body of a patient.

  • Patent number: 10265029
    Abstract: Systems and methods for generalized precursor pattern discovery that work with a wide range of biomedical signals and applications to detect a wide range of medical events are disclosed. In some embodiments, the methods and systems do not require domain-specific knowledge or significant reconfiguration based on the medical event being analyzed, hence it is also possible to discover patterns previously unknown to experts. In some embodiments, to build precursor pattern detection models, the system obtains annotated monitoring data. Positive and negative segments are extracted from the annotated monitoring data, and are preprocessed. Features are extracted from the preprocessed segments, and selected features are chosen from the extracted features. The selected features are classified to create the precursor pattern detection model The precursor pattern detection model may then be used in real time to detect occurrences of the medical event of interest.

  • Patent number: 10238319
    Abstract: A method to identify feature points associated with the heart valve movement, heart contraction or cardiac hemodynamics is revealed. The mechanocardiography (MCG) is a technology that makes use of vibrational waveforms acquired using at least one gravity sensor attached on one of the four heart valve auscultation sites on the body surface. The data of the electrocardiography (ECG) is recorded simultaneously with the MCG. The feature points are identified by comparing P, R and T points of synchronized ECG with the MCG spectrum. By the time sequences and amplitudes of the feature points, the method provides additional clinical information of cardiac cycle abnormalities for diagnosis.

  • Patent number: 10219978
    Abstract: An acupuncture device can include a frame, an enclosure disposed on the frame to protect the frame, multiple stimulators mounted on the frame. The stimulators can be electrically coupled with a controller that transmits electric pulses to the stimulators for electro-acupuncture purpose. The size of the frame is adjustable to fit different body sizes of the users. The stimulators can be carried by the adjustment of the frame. The acupuncture device can also include one or more position references and the stimulators are positioned at relative distances from the position references. When the size of the frame is adjusted, the stimulators are carried by the frame to new positions that are at relative distances from the position references in proportionality with the extent of adjustment of the frame. Hence, the relative distance between a stimulator and a position reference in light of the size of the frame is maintained.

  • Patent number: 10179246
    Abstract: A wearable cardioverter defibrillator (WCD) system includes a processor, a memory, a wireless communication module (DWCM), and an NFC tag that stores information for how an accessing device may access the DWCM wirelessly. An accessing device such as a defibrillator configurator with an NFC reader may read the NFC tag of the WCD system, if it has adequate permission to do so. Upon so reading, the accessing device will know how to address the DWCM wirelessly, and thus install or update configuration data, software updates, or request memory downloads from operations. The use of the NFC tag requires close proximity, which hampers both inadvertently programming the wrong WCD system, plus a WCD system being attacked maliciously.
