Abstract: Autonomous machine navigation techniques may generate a three-dimensional point cloud that represents at least a work region based on feature data and matching data. Pose data associated with points of the three-dimensional point cloud may be generated that represents poses of an autonomous machine. A boundary may be determined using the pose data for subsequent navigation of the autonomous machine in the work region. Non-vision-based sensor data may be used to determine a pose. The pose may be updated based on the vision-based pose data. The autonomous machine may be navigated within the boundary of the work region based on the updated pose. The three-dimensional point cloud may be generated based on data captured during a touring phase. Boundaries may be generated based on data captured during a mapping phase.

Abstract: A depth camera assembly (DCA) determines depth information for a scene in a field of view of the DCA. The DCA includes a structured light (SL) illuminator, a camera, and a controller. The SL illuminator includes a source assembly, a SL element, a liquid crystal (LC) array, and a polarizer. The source assembly generates light, and the SL element generates a SL pattern using the generated light source. The LC array includes a plurality of addressable cells configured to polarize the SL pattern in accordance with adjustment instructions. The polarizer attenuates portions of the SL pattern based on the polarization of the portions of the SL pattern. The camera captures an image of the SL pattern, and the controller identifies portions of the image that are saturated and generates adjustment instructions based in part on the identified portions of the image, and provides the adjustment instructions to the LC array.

Abstract: Methods, systems, and devices for robotic navigation are described. A robotic device such as a robotic vacuum or a robotic assistant may navigate a first surface. In some cases, navigating the first surface may include removing debris from the first surface. The robotic device may identify a location of a track that connects the first surface to a second surface that is vertically displaced from the first surface. The robotic device may engage the track based at least in part on the identified location. The robotic device may ascend to the second surface by activating an actuator and navigate the second surface (e.g., may remove debris from the second surface, may map the second surface, etc.).

Abstract: A head-mounted display (HMD) divides an image into a high resolution (HR) inset portion at a first resolution, a peripheral portion, and a transitional portion. The peripheral portion is downsampled to a second resolution that is less than the first resolution. The transitional portion is blended such that there is a smooth change in resolution that corresponds to a change in resolution between a fovea region and a non-fovea region of a retina. An inset region is generated using the HR inset portion and the blended transitional portion, and a background region is generated using the downsampled peripheral portion. The inset region is provided to a HR inset display, and the background region is provided to a peripheral display. An optics block combines the displayed inset region with the displayed background region to generate composite content.

Abstract: This invention includes a framework and method to enable the transformation of video content into a format that allows for mapping and, hence, identification of individual sections (scene segments or otherwise) of the media content. It includes a means of ingesting images and video frames into a database. Consumer products can be matched with the images and/or objects in the images. A consumer can access the content by submitting a digital image taken on a mobile device. One or more objects in the user submitted image can be matched with products and/or commercial/promotional materials.

Abstract: Aspects may augment a robotic vehicle with one or more virtual features. In some implementations, streaming video including a first-person view (FPV) of a robotic vehicle is presented on a display of a controller as the robotic vehicle traverses a course. A virtual object may be presented on the display of the vehicle controller, and a virtual contact between the robotic vehicle and the virtual object may be detected. If the virtual object is a virtual obstacle, the robotic vehicle may be penalized for making virtual contact with the virtual obstacle. If the virtual object is a virtual reward, the robotic vehicle may be rewarded for making virtual contact with the virtual reward.

Abstract: Aspects may provide navigation assistance to guide a robotic vehicle through a course defined by a plurality of gates each including a fiducial marker that encodes a location, an ordering, and a pose of the corresponding gate. In some implementations, an optimal trajectory may be generated through the course and used to determine whether to provide navigation assistance to the robotic vehicle. The optimal trajectory may include a reference path that extends through openings formed in center portions of the gates, and may be used to create a virtual tunnel indicating a maximum distance that the robotic vehicle may deviate from various points along the reference path. If the robotic vehicle deviates from the optimal trajectory by more than the distance while traversing the course, navigation assistance may be provided to the robotic vehicle.

Abstract: Aspects may define a race course using a plurality of gates each including a fiducial marker that encodes a location, an ordering, and a pose of the corresponding gate. Each of the gates may include an opening through which robotic vehicles participating in a race may traverse, and a flight path may be defined through the opening of the gates. Each fiducial marker may be displayed around a perimeter of the opening of a corresponding gate, and may include a unique pattern that conveys the location, ordering, and pose of the corresponding gate to video cameras provided on the robotic vehicles. A pilot may use the fiducial markers presented on the gates to navigate the robotic vehicle through the race course, for example, so that the pilot may not need to rely solely upon the first-person view provided by the streaming video transmitted from the robotic vehicle.

Abstract: The present invention relates to a method for the real-time identification of seizures in an Electroencephalogram (EEG) signal. The method provides for patient-independent seizure identification by use of a multi-patient trained generic Support Vector Machine (SVM) classifier. The SVM classifier is operates on a large feature vector combining features from a wide variety of signal processing and analysis techniques. The method operates sufficiently accurately to be suitable for use in a clinical environment. The method may also be combined with additional classifiers, such a Gaussian Mixture Model (GMM) classifier, for improved robustness, and one or more dynamic classifiers such as an SVM using sequential kernels for improved temporal analysis of the EEG signal.
