Abstract: A system for interpreting electrocardiograms receives a first electrocardiogram waveform, and identifies a feature in the first electrocardiogram waveform. The system retrieves one or more second electrocardiogram waveforms recorded at a point in time prior to the first electrocardiogram waveform. The system extracts the feature from the one or more second electrocardiogram waveforms, and generates one or more interpretive statements based on a comparison of the feature identified in the first electrocardiogram and the feature extracted from the one or more second electrocardiogram waveforms.

Abstract: Disclosed are various approaches for providing personalized recommendations in a privacy preserving manner. A request from a provider application is received, the request comprising an anonymized user identifier and a navigation identifier that identifies a location of a user associated with the anonymized user identifier within a user interface of the provider application. A user associated with the anonymized user identifier is identified. Then, an activity history of the user is analyzed in order to select a layout order, wherein the layout order is selected based at least in part on the navigation identifier and the activity history of the user. The layout order is then provided to the provider application.

Abstract: An aerial robot system may include an aerial robot having an airframe, a piezo actuator, a wing connected to the piezo actuator, and a photovoltaic cell. The system may further include a laser source configured to emit a laser beam oriented toward the photovoltaic cell for conversion by the photovoltaic cell into electrical energy. The aerial robot may further include a boost converter connected to the photovoltaic cell and configured to raise a voltage level of the electrical energy, and a signal generator connected to the boost converter and configured to generate an alternating signal. The piezo actuator is connected to the signal generator to move according to the alternating signal to cause the wing to move in a flapping motion to generate aerodynamic force that moves the robot. Methods for manufacturing aerial robots and corresponding electronics are also disclosed herein.
