Abstract: Techniques for aligning images generated by an integrated camera physically mounted to an HMD with images generated by a detached camera physically unmounted from the HMD are disclosed. A 3D feature map is generated and shared with the detached camera. Both the integrated camera and the detached camera use the 3D feature map to relocalize themselves and to determine their respective 6 DOF poses. The HMD receives the detached camera's image of the environment and the 6 DOF pose of the detached camera. A depth map of the environment is accessed. An overlaid image is generated by reprojecting a perspective of the detached camera's image to align with a perspective of the integrated camera and by overlaying the reprojected detached camera's image onto the integrated camera's image.

A second plate is positioned at the second end of the housing and rotatable about the axis of rotation such that the second plate selectively allows the working fluid to flow out of the outlet of the chamber. The first plate and the second plate are rotatable about the axis of rotation so as to hold a volume of the working fluid at constant density as a heat source imparts thermal energy thereto.

Abstract: A suction and irrigation implement includes a handpiece, a pair of aligned adjacent valve assemblies, a rocker and a hub. The body may be transparent to allow visualization of aspirated substances. The valve assemblies include a plunger with a conical core that increases the area of the valve opening with increased depression. The rocker, a pivoting actuator, opens one valve assembly at a time, thereby preventing simultaneous irrigation and suction. A suction and irrigation tube connects to the hub, which may be rotated to adjust the orientation of the tube, while the implement is in use. Detents define specific orientations.

Abstract: Techniques for evaluating multiple images, which originate from multiple different sources, and for selecting specific images to generate an overlaid image are disclosed. A first set of system camera images (e.g., based on a first FPS rate) and a second set of external camera images (e.g., based on a second FPS rate) are obtained. A set of rules are accessed in order to govern a selection process for selecting a specific system camera image and a specific external camera image. The selected images are designated for use in generating an overlaid image. The selection process is performed using the accessed set of rules. The overlaid image is generated by overlaying and aligning content obtained from the selected images.

Abstract: Techniques for generating a high resolution full color output image from lower resolution sparse color input images are disclosed. A camera generates images. The camera's sensor has a sparse Bayer pattern. While the camera is generating the images, IMU data for each image is acquired. The IMU data indicates a corresponding pose the camera was in while the camera generated each image. The images and IMU data are fed into a motion model, which performs temporal filtering on the images and uses the IMU data to generate a red-only image, a green-only image, a blue-only image, and a monochrome image. The color images are up-sampled to match the resolution of the monochrome image. A high resolution output color image is generated by combining the up-sampled images and the monochrome image.

Abstract: Disclosed herein are techniques for providing an illumination system that emits illumination into an environment while also enabling that system to be undetectable to certain types of external light detection systems. The system includes a single photon avalanche diode (SPAD) low light (LL) detection device and a light emitting device. The light emitting device provides illumination having a wavelength of at least 950 nanometers (nm). An intensity of the illumination is set to a level that causes the illumination to be undetectable from a determined distance away based on the roll off rate of the light. While the light emitting device is providing the illumination, the SPAD LL detection device generates an image of an environment in which the illumination is being provided.

Abstract: A detection system detects malfunctions in an autonomous farming vehicle during an autonomous routine using one or more models and data from sensors coupled to the autonomous farming vehicle. The models may include machine-learned models trained on the sensor data and configured to identify objects indicative of an operational or malfunctioning component within a tilling assembly such as a tilling shank or sweep. Additionally, a machine-learned model may be trained on sensor data to detect whether debris has plugged the tilling assembly of the autonomous farming vehicle. In response to detecting a malfunction or a plug, the detection system may modify the autonomous routine (e.g., pausing operation) or provide information for the malfunction to be addressed (e.g., the likely location of a malfunctioning sweep that has detached from the tilling assembly).

Abstract: Computing resources are managed in a computing network comprising a computing service provider and an edge computing network. The edge computing network receives an indication of a disconnection of communications between the computing service provider and the edge computing network. In response to the indication, the edge computing network initiates an autonomous mode at the edge computing network. The edge computing network is configured to continue providing computing and network services at the edge computing network while the edge computing network is operating in the autonomous mode.

Abstract: A processing system receives a user-generated media recording, and metadata associated with the user-generated feedback, from a first device. The user-generated media recording is a recording of the public end-user captured during a live media broadcast using a public-user interface on the first device. The metadata includes information linking the user-generated media recording to the live media broadcast. The system stores the user-generated media recording and the first metadata in one or more storage devices, and transmits a version of the user-generated media recording and at least a portion of the first metadata to a private-user interface on a second device. The private-user interface is configured to receive input from a private end-user selecting the version of the user-generated media recording for broadcast during the same live media broadcast during which the user-generated media recording was created.

Abstract: A system for dark current compensation in SPAD imagery is configurable to capture an image frame with the SPAD array and generate a temporally filtered image by performing a temporal filtering operation using the image frame and at least one preceding image frame. The at least one preceding image frame is captured by the SPAD array at a timepoint that temporally precedes a timepoint associated with the image frame. The system is also configurable to obtain a dark current image frame. The dark current image frame includes data indicating one or more SPAD pixels of the plurality of SPAD pixels that detect an avalanche event without detecting a corresponding photon. The system is also configurable to generate a dark current compensated image by performing a subtraction operation on the temporally filtered image or the image frame based on the dark current image frame.

Abstract: Techniques for correcting an overlay misalignment between an external camera image and a system camera image are disclosed. A first system camera image and a first external camera image are acquired. A first visual alignment is performed between those two images to produce an overlaid image. Some of the content in the overlaid image is surrounded by a bounding element. A position of the bounding element is modified based on movements of the system camera and/or the external camera. In response to performing a second visual alignment using new images, an update vector is computed. Relative movement between the two cameras is determined. Based on the movement and based on the update vector, the bounding element is progressively transitioned to a corrected position in the overlaid image. A speed by which the bounding element is progressively transitioned is proportional to the amount of movement.
