Abstract: A method for determining a risk of decompensated heart failure in a user includes receiving a first set of data that is fixed with respect to time. A machine-learning model generates one or more initial risk factors based on the first set of data. A second set of data for the user that dynamically updates over time is received from a wearable cardiovascular physiology monitor. The machine-learning model is used to generate dynamic data classifiers based on the one or more initial risk factors. Aggregate risk scores for the user are then indicated based on an evaluation of the second set of data against the dynamic data classifiers. In this way, static electronic medical records may be combined with dynamic, real-time data from wearable cardiovascular physiology monitors to provide an accurate and continuously updating risk of decompensated heart failure for a user.

Abstract: A transit fare approach that offers a transit agency the ability to cap how many transit passes of a particular type in a given fare cycle would be equivalent of buying a discounted transit product (like a weekly pass, a bi-weekly pass, or a monthly pass). Once this equivalent is reached by a rider, the system automatically gives the rider the corresponding discount pass for free. The free pass remains activated and good for the remainder of the fare cycle. A software module provides a user app for the rider's mobile device and a controller app for a control unit of the transit agency, both of which operate in conjunction with each other to monitor the use of transit passes by the rider to determine when the rider qualifies for the fare cap-based free transit product and subsequently reward the rider with the free use of the appropriate transit product.

Abstract: A first data window of a pulse waveform signal comprising a first number of samples is analyzed to determine a level of confidence that a pulse sensing device is placed correctly. If an initial level of confidence is met, the user is given positive feedback, and a second data window of a pulse waveform signal comprising a second, larger number of samples is analyzed. If an increased level of confidence is met, the user is given increased positive feedback. If a level of confidence is not met, the user is given negative feedback. If a final level of confidence is met, the user is given feedback that the pulse sensing device is placed correctly.

Abstract: A method and system, are provided herein, for automatic selection of one or more items (e.g., files, emails, etc.) in a user interface, based upon selection data received from a user (hard labels) and possibly also predicted (soft) labels (e.g., from a label prediction algorithm) based on behavior data associated with the selections. More particularly, a user selects and deselects items as positive and negative examples that are used as explicit labels to form an item selection list. The explicit labels are used possibly along with additional, predicted labels to create a list of generated items the user may want to select. This list is returned to the user interface as automatically selected items. In one example, the selection list may be iteratively updated upon receiving subsequent user selection data (e.g., user may select items incorrectly selected) by determining alternative items that the user may be interested in selecting.

Abstract: A system for transducing arterial pressure includes a one-piece flexible cap configured to fit around a flexible piezo-electric sensor that is configured to alter an internal resistance upon deflection. The flexible cap includes a deflection wall configured to deflect towards the flexible piezo-resistive sensor in proportion to pressure applied by the artery. A pressure-transducing medium is sealed between the one-piece flexible cap and the flexible piezo-resistive sensor, such that deflection of the deflection wall towards the flexible piezo-resistive sensor causes proportional deflection of the flexible piezo-resistive sensor.
