Abstract: Determining an instantaneous vehicle characteristic (e.g., at least one yaw rate) of an additional vehicle that is in addition to a vehicle being autonomously controlled, and adapting autonomous control of the vehicle based on the determined instantaneous vehicle characteristic of the additional vehicle. For example, autonomous steering, acceleration, and/or deceleration of the vehicle can be adapted based on a determined instantaneous vehicle characteristic of the additional vehicle. In many implementations, the instantaneous vehicle characteristics of the additional vehicle are determined based on data from a phase coherent Light Detection and Ranging (LIDAR) component of the vehicle, such as a phase coherent LIDAR monopulse component and/or a frequency-modulated continuous wave (FMCW) LIDAR component.

Abstract: The present discussion relates to structures and devices to facilitate application of an ultrasound therapy beam to a target anatomic region in a replicable manner. In certain aspects, adjustable positioning structures are described that allow a general probe positioning structure to be configured for a specific patient in a manner that allows the device to be used repeatedly to target the anatomic region, even when in non-clinical settings. In other aspects, a probe positioning structure is fabricated that is specific to a respective patient anatomy, such that use of the probe positioning structure provides repeatable targeting of the target anatomic region, even when in non-clinical settings.

Abstract: Determining classification(s) for object(s) in an environment of autonomous vehicle, and controlling the vehicle based on the determined classification(s). For example, autonomous steering, acceleration, and/or deceleration of the vehicle can be controlled based on determined pose(s) and/or classification(s) for objects in the environment. The control can be based on the pose(s) and/or classification(s) directly, and/or based on movement parameter(s), for the object(s), determined based on the pose(s) and/or classification(s). In many implementations, pose(s) and/or classification(s) of environmental object(s) are determined based on data from a phase coherent Light Detection and Ranging (LIDAR) component of the vehicle, such as a phase coherent LIDAR monopulse component and/or a frequency-modulated continuous wave (FMCW) LIDAR component.

Abstract: A system for content upsampling comprises a console and a head-mounted display (HMD). The console can select content for presentation and provide the content at a first frame rate. The HMD outputs fast calibration data comprising one or more intermediate estimated positions of a reference point on the HMD. The HMD estimates future positions of the HMD using the fast calibration data, and generates synthetic frames using frames from the content and the future positions of the HMD. The HMD then upsamples the content from the first frame rate to a second frame using the synthetic frames to generate augmented content, wherein the second frame rate is faster than the first frame rate. The HMD presents the augmented content at the second frame rate via an electronic display.

Abstract: In one embodiment, a computing system may access a first image that is generated at a first frame rate. The system may determine whether a change of a user viewpoint with respect to one or more display contents satisfies a threshold criterion. The system may select an operation mode from a first operation mode and a second operation mode based on the determination whether the change of the user viewpoint satisfies the threshold criterion. The system may generate a number of second images at a second frame rate higher than the first frame rate. When the selected operation mode is the first operation mode, the second images may be generated using a resampling process. When the selected operation mode is the second operation mode, the second images may be generated by transforming one or more previously generated second images that are generated based on the first image.
