Abstract: A computer network may include a Non-IP subnetwork with a frontend device, an IP subnetwork with a backend device, and a gateway connecting the Non-IP subnetwork with the IP subnetwork and translating communication therebetween. The communication for authentication and/or encryption between the backend device and the gateway is an IP communication based on an IP security protocol and a Non-IP communication between the gateway and the frontend device. A gateway is configured to provide a virtual IP communication endpoint dedicated to the frontend where a secure end-to-end communication may be established between the backend device and the frontend device. The Non-IP communication is applied to transmit a transcription of the request datagram to the frontend device. The frontend device is configured to generate a response datagram and to transmit a transcription of the response datagram to the gateway by applying the Non-IP communication.

Abstract: The present disclosure relates to various embodiments of an optical component for a LIDAR Sensor System. The optical component includes a first photo diode implementing a LIDAR sensor pixel in a first semiconductor structure and configured to absorb received light in a first wavelength region, a second photo diode implementing a camera sensor pixel in a second semiconductor structure over the first semiconductor structure and configured to absorb received light in a second wavelength region, and an interconnect layer (e.g. arranged between the first semiconductor structure and the second semiconductor structure) including an electrically conductive structure configured to electrically contact the second photo diode. The received light of the second wavelength region has a shorter wavelength than the received light of the first wavelength region.

Abstract: The present disclosure relates to various embodiments of an optical package for a LIDAR sensor system having a substrate including an array of a plurality of capacitors formed in the substrate, a plurality of switches formed in the substrate, where each switch is connected between at least one laser diode and at least one capacitor of the plurality of capacitors; and at least one laser diode being mounted in close proximity to the plurality of capacitors on the substrate in order to provide small parasitic inductances and capacitances. A processor is configured to control the plurality of switches to control a first current flow to charge the plurality of capacitors, wherein the processor is configured to control the plurality of switches to control a second current flow to drive the at least one laser diode with current discharged from at least one capacitor of the plurality of capacitors.

Abstract: A computer network may include a Non-IP subnetwork for communication between the gateway and the frontend device, an IP subnetwork for communication between the gateway and at least one backend device, and a gateway connecting the Non-IP subnetwork with the IP subnetwork and translating communication therebetween. The IP communication is based on an IP security protocol, providing means for authentication and/or encryption. The gateway mediates handshaking for establishing a secure tunnel for secure end-to-end communication between the backend device and the frontend device. The secure tunnel is set to apply a session key. The gateway and the backend device exchange datagrams with handshaking parameters. The Non-IP messages are exchanged with a subset of the handshaking parameters. The backend device and the frontend device generate the session keys and to authenticate the handshaking incorporating the handshaking parameters and subset of handshaking parameters, respectively.
