Abstract: Techniques and apparatuses are described that facilitate ambient computing using a radar system. Compared to other smart devices that rely on a physical user interface, a smart device with a radar system can support ambient computing by providing an eye-free interaction and less cognitively demanding gesture-based user interface. The radar system can be designed to address a variety of challenges associated with ambient computing, including power consumption, environmental variations, background noise, size, and user privacy. The radar system uses an ambient-computing machine-learned module to quickly recognize gestures performed by a user up to at least two meters away. The ambient-computing machine-learned module is trained to filter background noise and have a sufficiently low false positive rate to enhance the user experience.

Abstract: A downhole tool comprises a heater including a container enclosing a volume of compacted thermite. A volume of flowable alloy is provided above the heater. A fusible bulkhead may be provided between the heater and the alloy and provides for direct conduction of heat from the heater to the alloy. A housing containing the alloy may be separated from the heater by heating a fusible socket that anchors an end of a tensioned support member. The thermite may define an internal volume adapted to receive alloy. The heater may be activated to melt the alloy and the alloy may then solidify to form a bore-sealing plug.

Abstract: An indoor location is mapped into a grid comprising grid cells, each cell associated with items or objects detected as being present in the corresponding cell. The grid, grid cells, and linked items and/or objects are generated and updated using an Augmented Reality (AR) algorithm that maps a physical environment into cells and measures distances and directions within the environment relative to each cell. Walking paths (routes) to the items within the indoor location are generated using the grid information. As a user walks a path, the user's position within the indoor location is mapped and tracked to the cells and the path revised based on the user's actual position. A user device provides video via an AR application to track the user's position; a rendering of the position and path are superimposed within the video being viewed by the user on the user-operated device.

Abstract: Techniques for determining calibration data associated with a radio frequency (RF) testing environment are discussed herein. For example, an RF signal can be input to the RF enclosure and selectively applied to discrete attenuators. The attenuators can attenuate a strength of the signal and a signal strength can be measured by various user equipment (UEs) that are located within an RF enclosure. In some examples, a plurality of measured reference signal received power (RSRP) values can be determined by a plurality of UEs associated with a particular attenuation level. Different attenuation levels can be measured, and an average attenuation can be determined for attenuation steps. Measured attenuation steps can be extrapolated to other attenuation levels to expedite the calibration process. Then, a testing plan can be applied to the RF enclosure and the calibration data can be used to ensure accurate signals for testing UEs.

Abstract: In various examples, multimodal image data may be used to generate a set of top-down tile images, which are applied to a deep neural network generator architecture model to produce lane marking-specific heatmap images corresponding to the set of top-down tile images. The multimodal sensor data may include LIDAR-captured intensity channel data, LIDAR-captured feature height channel data, and optical color image channel data. The set of top-down tile images may be processed by the generator model to automatically detect lane boundaries and navigation boundaries to generate pixel-level heatmap images that may classify lane markings by marking characteristics such as line type and/or color. The generator model may comprise an encoder-decoder architecture, with multiscale feature extraction and/or context extraction functional layers intervening between the encoder model and the decoder model.
