Latency in a cloud security service provided via a network security device is reduced by receiving in the network security device a new network connection request for a connection between a local network device and a remote server. If a locally cached rule is applicable to the new network connection request, the applicable locally cached rule is applied to selectively allow the new network connection based on the rule. If no locally cached rule is applicable to the new network connection request, the new network connection request is forwarded to the remote server and to a cloud security service, and a response from the remote server is selectively forwarded to the local network device only upon receiving a determination by the cloud security device as to whether the new network connection is a security risk.

An endpoint in a network periodically generates a heartbeat encoding health state information and transmits this heartbeat to other network entities. Recipients of the heartbeat may use the health state information to independently make decisions about communications with the source endpoint, for example, by isolating the endpoint to prevent further communications with other devices sharing the network with the endpoint. Isolation may be coordinated by a firewall or gateway for the network, or independently by other endpoints that receive a notification of the compromised health state.

Subsequent to processing, the described method attaches the ultra-thin device layer to a roll of tape for removal from the temporary adhesive, followed by transfer to a demount roller, which then releases it onto a desired permanent surface. Utilizing the flexible nature of the ultra-thin device layer, the sequence of rollers is able to peel it from the temporary adhesive without any need for laser release processing or chemical adhesive removal while maintaining the thinned wafer in a planar form during processing. This transfer supports operations that include a change of orientation, such as from face up to face down.

A three-dimensional (3D) model of an object is recovered from two-dimensional (2D) images of the object. Each image in the set of 2D images includes the object captured from a different camera position and deformations of a base mesh that defines the 3D model may be computed corresponding to each image. The 3D model may also include a texture map that represents the lighting and material properties of the 3D model. Recovery of the 3D model relies on analytic antialiasing to provide a link between pixel colors in the 2D images and geometry of the 3D model. A modular differentiable renderer design yields high performance by leveraging existing, highly optimized hardware graphics pipelines to reconstruct the 3D model. The differential renderer renders images of the 3D model and differences between the rendered images and reference images are propagated backwards through the rendering pipeline to iteratively adjust the 3D model.

The present disclosure provides systems and methods that combine physics-based systems with machine learning to generate synthetic LiDAR data that accurately mimics a real-world LiDAR sensor system.

A system automatically identifies objects in an environment based on a walkthrough video and an annotated floorplan of the environment. The annotated floorplan indicates locations and types of objects that are expected to be in the environment. The system receives the walkthrough video and generates a 3D model of the environment. The system applies a machine learning model to the walkthrough video to identify regions within frames where objects are captured. After identifying the regions within frames of the walkthrough video that include objects, the system modifies corresponding regions of the 3D model to include the identified objects. For each of the identified objects, the system determines a likelihood of the identified object being present at a location in the environment based on a comparison of the modified 3D model and the annotated floorplan.
