Abstract: An electric vehicle having a heat exchanger formed in an aerodynamic airfoil shape comprising one or more body panels disposed along an outer surface of the vehicle having one or more fluidic chambers or micro-channels. The heat exchanger is adapted to provide effective and highly efficient heat transfer, and also to provide substantially reduced or negligible contribution to the aerodynamic drag. The heat exchanger includes a supplemental heat exchange system wherein at least a portion of the heat exchange capacity is provided by an inner heat exchange surface of the heat exchanger exposed to an interstitial space within the vehicle. Airflow is forced, via a fan for example, from an aerodynamically-efficient inlet, over the inner heat exchange surface, and exhausted through an aerodynamically-efficient outlet, thereby providing a supplemental heat exchange system including substantially reduced or negligible contribution to the aerodynamic drag.

Abstract: A dual trailing link, rear wheel suspension system for a vehicle is described. The trailing links have proximal ends coupled to the vehicle chassis and distal ends coupled to a bracket with a knuckle for the wheel. The distal ends have a larger distance between them than the proximal ends, allowing for an improved instantaneous center, which may be useful for determining lift/squat characteristics. The distal ends may be disposed proximate the knuckle, thereby providing the largest possible knuckle pivot radius, i.e., effective swingarm length, for a predetermined chassis-wheel distance, which provides a smoother, more comfortable riding experience. The disclosed arrangement makes maximum use of the space allotted for the rear suspension system and is suitable for use with an aerodynamic cowling for an energy efficient vehicle.

Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: Accurate vehicle localization is arguably the most critical and fundamental task for autonomous vehicle navigation. While dense 3D point-cloud-based maps enable precise localization, they impose significant storage and transmission burdens when used in city-scale environments. A highly compressed representation for LiDAR maps, along with an efficient and robust real-time alignment algorithm for on-vehicle LiDAR scans, is proposed here. The proposed mapping framework, requires less than 0.1% of the storage space of the original 3D point cloud map. In essence, mapping framework emulates an original map through feature likelihood functions. In particular, the mapping framework models planar, pole and curb features. These three feature classes are long-term stable, distinct and common among vehicular roadways. Multiclass feature points are extracted from LiDAR scans through feature detection.

Abstract: Pasting content from a clipboard buffer as structured tabular data. A computer system determines a data type of content within a clipboard buffer. Based on the data type of the content, the computer system identifies a tabular pattern analysis technique to apply to the content. Based on applying the tabular pattern analysis technique to the content, the computer system identifies a portion of tabular content within the content. Using a clipboard application programming interface, the computer system presents the portion of tabular content to an application as paste data that is structured as a set of rows and a set of columns.

Abstract: This disclosure describes various attributes and implementations of systems and methods for efficiently generating high accuracy landmark annotations for depth-based image or video data sets. For example, a Transpositional Tagging approach can automatically or semi-automatically find, identify, and track landmarks (such as human or animal joints, other structural landmarks, or other points of interest) that are visible in one imaging modality (such as infrared, optical, etc.), and transfer those labels to a second image modality (such as, e.g., near-IR depth images/videos). As a result, systems and methods provided herein can quickly generate highly specific training datasets that are then used to develop neural network models for detecting poses, positions, and/or movements in imaging modalities such as 3D and depth images.

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.
