Abstract: A wearable article is provided as a wearable component of a medical device configured with elements to accommodate electrode pads in a manner that offers flexibility, cushion, and temperature regulation for comfort of a patient, as well as facilitating distribution of pressure on the electrode pads against the body of the patient. A containment portion of the wearable article houses the electrode pad and a spacer structure. The spacer structure is flexible to move as the body of the patient moves and yet provides a level of stiffness for pressure on the underlying electrode. Numerous springy elements dispersed in the spacer structure provide a thickness and open space for air circulation through the spacer structure, resulting in temperature regulation of the wearable article.

Abstract: A wearable cardioverter defibrillator (WCD) comprises a plurality of electrocardiography (ECG) electrodes, a right-leg drive (RLD) electrode, and a plurality of defibrillator electrodes to contact the patient's skin when the WCD is delivering therapy to the patient, a preamplifier coupled to the ECG electrodes and the RLD electrode to obtain ECG data from the patient as one or more ECG vectors, a processor to receive ECG data from the preamplifier and an abort signal from a user interface, an isolation barrier to isolate the preamplifier from the processor, and a high voltage subsystem to provide a defibrillation voltage to the patient through the defibrillator electrodes in response to a shock signal received from the processor. A shock is provided when an abort signal is not received within a predetermined time period of a shock criterion being met. Less than one false alarm occurs every ten patient-days.

Abstract: An idler sprocket shaft support device for use with chain-driven equipment (e.g., snowblowers) is provided. The support device includes a spacer through which the sprocket shaft passes through, and an elongate support member coupled to the spacer and extending through an aperture in an adjacent support plate. By locking the elongate support member within the aperture in the adjacent support plate at a particular distance, the spacer also is locked thereby holding the sprocket shaft at a desired positional setting.

Abstract: “Artificial Intelligence” or “AI” technology can be applied to Wearable Cardioverter Defibrillators (“WCDs”) and other wearable medical equipment in various ways, including garment fitting and adjustment, analyzing electrocardiogram (“ECG”), other sensor data and/or other patient data in real time to detect/assess the patient's present condition and/or need for treatment for cardiac and other conditions (e.g., stroke, coughing, apnea, etc.), detect imminent failure of the wearable medical device components, capture and report data collected from the patient for presenting to clinicians, adjust thresholds for alarms and notifications based on patient's responses, improve patient compliance based on the patient's past non-compliant behavior and actions that resulted in the patient becoming compliant, provide tests to the patient, and learn the patient's responses to detect/assess the patient's present condition and/or need for treatment.
