Abstract: An example network security system includes one or more memories storing processor-readable instructions, and one or more processors configured to access the one or more memories and execute the processor-readable instructions to perform operations. The operations include receiving a network flow associated with communication between a plurality of hosts, obtaining a security label associated with the network flow, matching the security label or a flow attribute of the network flow against a plurality of security policies, and executing a security action on the network flow based on the matching to restrict unauthorized inter-host information flow among the plurality of hosts.

Abstract: Disclosed are various embodiments that facilitate efficient pairing of mixed-reality devices using gaze tracking. In one embodiment, a host device and at least one client device are identified from a plurality of computing devices. A key sequence cue is communicated to a first user via the host device. A graphical display is simultaneously presented via each of the computing devices with a plurality of indicia distributed across the graphical display. Eye gazes of the first user and at least one second user are tracked using a respective gaze tracking sensor of the computing devices. The eye gaze traces a sequence of a subset of the indicia corresponding to the key sequence cue. A cryptographic key is generated based at least in part on the eye gaze of the first user and the second user(s).

Abstract: Embodiments of the present disclosure introduce approaches for protecting bystander privacy in a wearable augmented reality (AR) device. In one embodiment, a video frame is captured via a camera of the wearable AR device, and faces are detected in the video frame. A first face is classified as a subject based at least in part on eye gaze tracking of a user of the wearable AR device by an eye gaze sensor of the wearable AR device. A second face is classified as a bystander based at least in part on the eye gaze tracking of the user. The second face is obscured in the video frame in response to the second face being classified as the bystander.

Abstract: A method may capture images of the vehicle lane using a camera attached to a moving vehicle. The method may determine, based on the captured one or more images, locations of a plurality of first lane markings defining a left extent of a lane and a plurality of second lane markings defining a right extent of the lane. The method may project the determined locations in the one or more images to locations in a coordinate system of the roadway. The method may determine a plurality of widths of the lane in the coordinate system of the roadway over a range of distances. The method may determine variations of the lane widths in the coordinate system of the roadway over the range of distances. The method may rescale the lane widths over the range of distances in the coordinate system to reduce determined variations of the lane widths.

Abstract: The application belongs to the technical field of reactor of dehydrogenation apparatus, in particular to reactor of UOP propane dehydrogenation apparatus and maintenance method thereof. The reactor includes a reduction cylinder and a catalytic cylinder connected end to end, and a feeding elbow located at a lower end of the catalytic cylinder. Inside the catalytic cylinder there is a conical distributor, an inner net and an outer net located on a same axis and arranged in sequence from inside to outside. Upper ends of the conical distributor, the inner net and the outer net are all connected with an upper cover plate through bolt gaskets. Through the integral design of the inner net, the outer net and the lower cover plate, it is convenient to lift out as a whole, and workers may be prevented from being dispatched to go down into the narrow reactor to dismantle the bolts.

Abstract: Techniques for monitoring and diagnosing states of wireless network elements having a known impact on uplink interference are presented. In an aspect, a method includes receiving, by a system including a processor, diagnostic data for a cellular network including strength data representative of strengths of radio frequency signals, prior to demodulation, respectively received at a plurality of antennas of a base station of the cellular network over a defined duration of time and at a defined sampling rate. The method further includes, based on analyzing the strength data by the system, determining by the system, a state of a network element of the cellular network.
