Abstract: An administered authentication system can authenticate an artificial reality device using an authorization record between a user account and an artificial reality device. In some implementations, the authorization record is created in response to activation of a user account-specific key sent to a user-supplied contact, where an artificial reality device identifier was provided with the user-supplied contact. In other implementations, the authorization record is created in response to activation of a user account-specific key provided to the artificial reality device as a code, where activation of the key includes adding an artificial reality device identifier to a key activation message. In yet other implementations, the authorization record is created in response to an application associated with a user account activating an artificial reality device-specific key, with an artificial reality device identifier, that is provided via the artificial reality device.

Abstract: Systems and methods are provided for filtering atmospheric conditions from LiDAR point clouds. The method includes generating, using a LiDAR system, at least one point cloud, wherein the LiDAR system includes a processor. The method further includes, using the processor, identifying and isolating one or more ground points within a point cloud of the at least one point cloud, wherein the one or more ground points indicate a ground portion within an environment of the point cloud, filtering out the ground portion from the point cloud, generating an initial processed point cloud, identifying and isolating one or more atmospheric condition points within the initial processed point cloud, wherein the one or more atmospheric condition points indicate one or more atmospheric conditions within an environment of the processed point cloud, and filtering out the atmospheric condition points from the initial processed point cloud, generating a final processed point cloud.

Abstract: An apparatus for modifying an electrical circuit includes a first electrical contact, a second electrical contact, an electrical coupler formed of an electrically conductive material, a first assembly including a cavity, a driving portion, an inhibiting portion, and a second assembly electrically coupled to the second electrical contact. The electrical coupler is moveable within the cavity along a movement axis, a wall of the cavity is electrically coupled to the first electrical contact and to the electrical coupler, and when the electrical coupler is disposed at an initial position within the cavity, the electrical coupler is not electrically coupled to the second electrical contact. The driving portion applies a first force on the electrical coupler in a movement direction along the movement axis. The inhibiting portion inhibits the movement of the electrical coupler along the movement axis.

Abstract: Systems, apparatus, and methods of monitoring and reducing snore are discussed herein. Some embodiments may provide for a system including a snore detection module, a movement detection module, a control module, and an actuation module. The snore detection module may be configured to detect snore, such as by detecting vibrations caused by snoring. When snoring is detected, the control module may be configured to instruct the actuation module to apply stimulation to the user that is calibrated to cause the user to shift sleeping position without disturbing sleep. The movement detection module may be configured to monitor user movement. If the user fails to move in response to the actuation, the actuation module may increase the intensity of the actuation. If the user responds to the actuation, the process may be repeated after a predetermined delay to provide continuous snore monitoring and correction throughout user sleep.

Abstract: A linear voltage regulator includes a Miller frequency compensation having a movable zero, which tracks the frequency of the load pole as the load condition changes. The compensated voltage regulator maintains stability under variable load conditions. Because of the Miller effect, DC open-loop gain and bandwidth are not sacrificed for stability. The compensated voltage regulator can therefore maintain high power supply rejection ratio (PSRR).
