  • Publication number: 20230421924
    Abstract: There is provided a pixel circuit for performing analog operation including a photodiode, a first temporal circuit, a second temporal circuit and an operation circuit. Within a first interval, the photodiode detects first light energy to be stored in the first temporal circuit. Within a second interval, the photodiode detects second light energy to be stored in the second temporal circuit. Within an operation interval, the first temporal circuit outputs a first detection signal having a first pulse width according to the first light energy and outputs a second detection signal having a second pulse width according to the second light energy for being calculated by the operation circuit.

  • Patent number: 11804961
    Abstract: A computer network includes a camera node, a network access node, a verification node, and a display node. Video content recorded by a camera at the camera node is transmitted to the display node and to the verification node for verification. The video content is verified at the display node and at the verification node. Recording metadata of the video content is stored in a distributed ledger and retrieved by the display node to verify the video content. The verification node receives, from the network access node, verification data for verifying the video content.

  • Patent number: 11736498
    Abstract: A system for stateful detection of cyberattacks includes an endpoint computer and a backend computer system. The endpoint computer monitors for cyberattacks and sends out queries for detected security events. The backend computer system stores observation data that are included in the queries. The backend computer system combines current observation data from a current query, relevant observation data from previous queries, and relevant cybersecurity data. The combined data are evaluated for cyberattacks.
