Abstract: This document describes a thermal-control system that may be integrated into a mesh network device and associated mesh network devices. The thermal-control system, which may include a heat sink, multiple heat spreaders, and a heat shield, is such that heat originating from IC devices populating a printed circuit board of the mesh network device may be transferred to a housing component of the mesh network device for external dissipation to maintain a desired thermal profile of the mesh network device.

Abstract: The present disclosure provides systems and methods that perform structure-based access control. In particular, rather than relying upon a user-specific credential scheme, which can require manual sharing of user-specific credentials and/or switching between the multiple accounts to access the particular devices, applications, or services associated with such accounts, the systems and methods of the present disclosure facilitate user credentials to be inherited by or otherwise assigned to a structure identifier associated with a structure (e.g., a home in which the user resides), thereby generating a set of structure credentials. This enables other users in the structure, who may be part of a collaborative user group, to access devices, applications, and/or services using the structure credentials.

Abstract: A head-mounted device, such as augmented reality glasses, can be configured to track screen time. The head-mounted device can advantageously track screen time across a variety of devices whether or not they are configured to such measurements. Various modes for tracking the screen time may be used based on accuracy, power consumption, and privacy. The head-mounted device may track in a mode based on a battery level, a device setting or a user input. The head-mounted device may accumulate screen times in a database and in some implementations, can link screen times with devices in the database based on device information gathered by the head-mounted device during the tracking process. The head-mounted device may be configured to generate and display an alert based on one or more rules about screen time.

Abstract: Training and/or utilizing a hierarchical reinforcement learning (HRL) model for robotic control. The HRL model can include at least a higher-level policy model and a lower-level policy model. Some implementations relate to technique(s) that enable more efficient off-policy training to be utilized in training of the higher-level policy model and/or the lower-level policy model. Some of those implementations utilize off-policy correction, which re-labels higher-level actions of experience data, generated in the past utilizing a previously trained version of the HRL model, with modified higher-level actions. The modified higher-level actions are then utilized to off-policy train the higher-level policy model. This can enable effective off-policy training despite the lower-level policy model being a different version at training time (relative to the version when the experience data was collected).

Abstract: A first request for content from a client device is received. The first request includes a resource locator provided by an authorizing data service to authorize the client device to obtain the requested content. The resource locator includes a first digital signature associated with authorization of the client device to access the requested content, and a second digital signature associated with authorization of delivery of the requested content for access by the client device. An occurrence of an event is identified that indicates a change in the delivery of the requested content to the client device. A third digital signature associated with a changed delivery of the requested content is generated. A new resource locator is provided to the client device that includes the first digital signature and the third digital signature.

Abstract: Techniques are disclosed that enable training a plurality of policy networks, each policy network corresponding to a disparate robotic training task, using a mobile robot in a real world workspace. Various implementations include selecting a training task based on comparing a pose of the mobile robot to at least one parameter of a real world training workspace. For example, the training task can be selected based on the position of a landmark, within the workspace, relative to the pose. For instance, the training task can be selected such that the selected training task moves the mobile robot towards the landmark.

Abstract: An augmented reality (AR) subsystem including one or more machine learning models, automatically overlays an augmented reality image, e.g., a border or outline, that identifies cells of potential interest, in the field of view of the specimen as seen through the eyepiece of an LCM microscope. The operator does not have to manually identify the cells of interest for subsequent LCM, e.g, on a workstation monitor, as in the prior art. The operator is provided with a switch, operator interface tool or other mechanism to select the identification of the cells, that is, indicate approval of the identification of the cells, while they view the specimen through the eyepiece. Activation of the switch or other mechanism invokes laser excising and capture of the cells of interest via a known and conventional LCM subsystem.

A sparse matrix may be constructed from the aggregated browsing history, and dimensionally reduced, reducing entropy and providing anonymity for individual devices. Relevant content may be selected via quasi-personalized clusters representing similar browsing histories, without exposing individual device details to content providers.

Abstract: Techniques of generating a wavefront modulating element (WME) for imaging an object over a large image field include (i) designing a WME by breaking a large image into smaller sub-images and then applying an inverse imaging operation to find a segment of a plurality of segments (324-1 to-334-n) of a WME (in the from of DOE) producing a sub-image, and (ii) specifying an optical system to illuminate the WME resulting from each of the plurality of segments in such a way that the large image is reproduced as closely as possible. Along these lines, given a large target image in the far-field, a WME generation system decomposes the target image into sub-images. From this decomposition, the WME generation system then produces WME segments corresponding to the sub-images.

Abstract: A method for presenting a media item of a set of media items in a graphical user interface (GUI) of a client device is disclosed. The GUI is provided to present a media item in a set of media items. An input is received to select a first position on the GUI. A continuous movement of the input along a first axis of the GUI is detected to select a second position on the GUI from the first position. Responsive to detecting the continuous movement, a scrub rate corresponding to the second position in association with the first axis of the GUI is determined. A change in a direction of the continuous movement of the input towards a second axis of the GUI is detected. The second axis and the first axis are perpendicular to each other. Responsive to detecting the change in the direction of the continuous movement, one or more media items of the set of media items are advanced according to the scrub rate.
