Abstract: A method for a secure exchange of one or more messages between terminal devices in a network connecting said terminal devices. The method may include creating a message by a first terminal device, digitally signing the message with a private key of the first terminal device, and transmitting the signed message to at least a second terminal device. The creation of the message to be transmitted and the digital signing may occur before an event relating to an intended interworking of the terminal devices triggers the transmission of the signed message, wherein a content of the created message to be evaluated by the second terminal device is related to the event.

Abstract: 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.

Abstract: 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.

Abstract: 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.
