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.

Computer network with an IP subnetwork and a non-IP subnetwork and backend device, gateway, frontend device therefore and procedure for operation thereof

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.

A lighting fixture includes an optoelectronic light source, for example, designed to illuminate a room, and a modulatable supply circuit that is connected to the optoelectronic light source, wherein a current through or a voltage applied to the light source may be modulated by the modulatable supply circuit. A data stream generator is connected to a modulation input of the supply circuit. A trigger element that is connected to the data stream generator and configured to deliver a first signal to the data stream generator in response to a comparison of a counter value with a threshold value and an event signal. The data stream generator may be configured to deliver a modulation signal to the modulation input in response to an event signal and to the first signal, and the modulation signal encodes position information relative to a reference point.

Lighting fixture and arrangement having at least one lighting fixture

A method for controlling at least one wireless network access point in a building may include detecting whether a wireless communication device is connected to at least one wireless network access point and/or whether a person is present using a group of presence detectors. An illumination system may include at least one wireless network point and/or the group of presence detectors. An activated network access point may remain activated when the wireless network access point is connected to a wireless communication device and/or when a person is present. A network access point may be automatically deactivated when the wireless network access point is not connected to a wireless communication device and/or when a person is not present. A deactivated network access point may be automatically reactivated when the wireless network access point is connected to a wireless communication device and/or when a person is present. Combinations thereof are also possible.

A light guide arrangement for a mobile communications device for optical data transmission by an optoelectronic interface component of the communications device is provided. The light guide arrangement includes a light guide body with a greatest extent in the principal light guiding direction, a first optical coupling member for coupling the optoelectronic interface component to the light guide body, a second optical coupling member with a first lens element that has a first optical axis transverse to the principal light guiding direction and with a first optical deflection element arranged along the first optical axis, and a third optical coupling member with a second lens element that has a second optical axis transverse to the principal light guiding direction and with a second optical deflection element arranged along the second optical axis. The second optical axis differs from the first optical axis.
