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: A resonant DC-DC converter may include an input for inputting a DC supply voltage, an output for providing a DC voltage to a load, an output rectifier to convert the converter voltage into a DC voltage, a resonant half-bridge inverter comprising two switches in series with a first serial resonant circuit to adjust the output current of the converter, and a second serial resonant circuit to block DC current in the converter and provide current continuity within the converter. The resonance of the first serial resonant circuit is measured after every start of the converter and each measurement defines the switching frequency of the half-bridge inverter. The switches of the half-bridge inverter wherein the driving of the half-bridge inverter includes a key gap during operation thereof. The resonance frequency of the second serial resonant circuit is at least slightly above the switching frequency of the half-bridge inverter.

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: 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.
