Abstract: A Reconfigurable, Flexible Multi-User (RFMU) electronically steered antenna (ESA) includes a top panel and a number of side panels that enable many contacts simultaneously with varying gain requirements from a single, in situ, installation. The top panel includes multiple subarrays and can communicate with flyover satellites, and the side panels can communicate with satellites flying past a side of the ESA. The top panel and the side panels can achieve a beam steering that covers a full or partial, variable gain, hemispheric field-of-view (FoV). The RFMU ESA terminal top and side panels are scalable using flexible modular building blocks. This enables increased contacts, increased gain or a combination thereof sized to meet desired performance.

Abstract: An example non-transitory machine-readable storage medium includes instructions to, when executed by the processor, capture an image of a face of a user viewing a display device, identify a light source in the image, and identify light from the display device reflecting off the face of the user. The example instructions are also executable to determine a signature of the light in the image by 1) positively weighting a light measurement from the light source in the image and 2) negatively weighting a light measurement emanating from the display device and reflecting off the face of the user. The example instructions are also executable to modify a display device setting based on the signature of the light in the image.

Abstract: Methods, systems, and devices for postamble for multi-level signal modulation are described. One or more channels of a bus may be driven with a multi-level signal having at least two (2) distinct signal levels. After driving the bus with the multi-level signal, at least one (1) of the channels may be terminated. In some examples, the channel may be terminated to a relatively high signal level. Before termination, the channel may be driven with a postamble having an intermediate signal level. Driving the channel to an intermediate signal level before terminating the channel (e.g., to a high signal level) may avoid maximum transitions of the signal. For example, transitions between a lowest potential signal level and the high signal level (e.g., the termination level) may be avoided.

The method includes: receiving a document that includes a signature; detecting a first region within the document in which the signature is present; applying a region-based convolutional neural network to the detected first region in order to demarcate a boundary that surrounds the detected first region; detecting a second region within the document in which a name that relates to the signature is present, by scanning the document to obtain a set of text words and then applying a named entity recognition (NER) machine learning algorithm to determine which text words are names; and assigning a signatory name attribution to the name that is present in the second region, based on a calculated distance between the name and the demarcated boundary.

Abstract: In an image processing apparatus, an image acquisition section acquires captured images from a stereo camera of a head-mounted display. An image correction section performs correction on a partial image-wise basis, a partial image being smaller than one frame, while referring to a displacement vector map representing displacement vectors of pixels required for the correction.

The feature point comparison section associates feature points in a plurality of images with one another. A space information acquisition section acquires information as to a real space on the basis of correspondence information as to the feature points.

Abstract: An autonomous mobile device (AMD) that interacts with a user operates more effectively with reliable information about that user's pose. Occlusion due to obstacles or sensor field-of-view limits may prevent a sensor from “seeing” a user's torso or lower body while the face may remain visible. Face orientation alone produces unreliable results because a user frequently moves their head. Sensor data is acquired over time and used to determine face and body poses, with each pose representing a location and orientation in physical space of that portion of the user. A transform is determined that represents the relative arrangement of a face pose and a body pose at a particular time. If available, the body pose may be used as the user's pose. If the body pose is unavailable or unreliable at a given time, it may be inferred by applying the previously determined transform to the current face pose.

Abstract: Systems and methods for processing surveillance video streams using image classification and object detection are described. Video data from a video image sensor may be processed using an image classifier to determine whether an object type is present in a video frame. If the object type is present, the video frame and/or subsequent video frames may be processed using an object detector to provide additional object data, such as position information, for use in other video surveillance processes. In some examples, an event message may be generated and sent to a video surveillance application in response to selective object detection.
