Abstract: A method for determining a depth of a hidden structural element of an object, the method may include (i) obtaining contrast information regarding a contrast between (a) hidden structural element detection signals that are indicative of electrons emitted from the hidden structural element, and (b) surroundings detection signals that are indicative of electrons emitted from a surroundings of the hidden structural element; wherein the hidden structural element detection signals and the surroundings detection signals are detected as a result of a scanning of a region of the object, with an illuminating electron beam; wherein the region comprises the hidden structural element and the surroundings; and (ii) determining the depth of the hidden structural element based, at least in part, on the contrast information.

Abstract: A local sensing amplifier and a memory are provided. The local sensing amplifier is connected to a global signal line and is connected to a sense amplifier array by means of a local signal line and a complementary local signal line. The local sensing amplifier transmits a signal on the local signal line to the global signal line when a read control signal is received, and to transmit a signal on the global signal line to the local signal line when a write control signal is received. The local sensing amplifier includes a precharge circuit connected to a preset voltage source, the local signal line and the complementary local signal line. The preset voltage source provides a first voltage in a read-write interval and provide a second voltage in an idle period. The precharge circuit transmits first voltage to the local signal line and the complementary local signal line.

Abstract: Embodiments provide image display systems and methods for a camera calibration using a two-sided diffractive optical element (DOE). More specifically, embodiments are directed to determining intrinsic parameters of a camera using a single image obtained using a two-sided DOE. The two-sided DOE has a first pattern on a first surface and a second pattern on a second surface. Each of the first and second patterns may be formed by repeating sub-patterns that are lined when tiled on each surface. The patterns on the two-sided DOE are formed such that the brightness of the central intensity peak on the image of the image pattern formed by the DOE is reduced to a predetermined amount.

Abstract: Systems and methods for depth detection and virtual modeling using surgical robots during a surgical procedure are described. The robotic surgical systems include robotic arms with interchangeable surgical tools. An endoscope at the end of one of the robotic arms includes a depth sensor for detecting a distance from the camera to patient anatomy. The depth data and image data are used to generate a feature model of the patient anatomy for reference by a surgeon. The feature model is displayed to the surgeon in an augmented reality view with preoperative and intraoperative images mapped thereon for reference and guidance of a surgical procedure.

Abstract: An immersive content presentation system and techniques that can detect and correct lighting artifacts caused by movements of one or more taking camera in a performance area consisting of multiple displays (e.g., LED or LCD displays). The techniques include capturing, with a camera, a plurality of images of a performer performing in a performance area at least partially surrounded by one or more displays presenting images of a virtual environment. Where the images of the virtual environment within a frustum of the camera are updated on the one or more displays based on movement of the camera, and images of the virtual environment outside of the frustum of the camera are not updated based on movement of the camera. The techniques further include generating content based on the plurality of captured images.

Abstract: The present disclosure relates to chatbot systems, and more particularly, to batching techniques for handling unbalanced training data when training a model such that bias is removed from the trained machine learning model when performing inference. In an embodiment, a plurality of raw utterances is obtained. A bias eliminating distribution is determined and a subset of the plurality of raw utterances is batched according to the bias-reducing distribution. The resulting unbiased training data may be input into a prediction model for training the prediction model. The trained prediction model may be obtained and utilized to predict unbiased results from new inputs received by the trained prediction model.

Abstract: A relative risk can be determined using an originating Internet Protocol (IP) address as an identifying factor for purposes of authenticating a user. The originating IP address can be used as an identifying factor for a particular user account to determine potentially fraudulent activity and reduce the risk of fraud. This additional identifying factor can be used as a part of an overall authentication platform to help screen fraud attempts and to authenticate valid and non-fraudulent users. Using certain aspects can distinguish whether originating IP addresses are public or private. Some examples can track and match originating IP addresses to user accounts and also can keep track of recently active sessions for each IP address.

Abstract: This application is directed to a home monitoring and control system including a doorbell installed at a door of a home. The doorbell has a button configured to, upon being pressed, wirelessly initiate a first communication to indicate presence of a person at the door. The doorbell also has a camera configured to capture video data within a field of view, and a processor configured to cause a communication component to enable the first communication and wirelessly stream via a remote server the video data captured by the camera to a monitoring device associated with an occupant of the home.
