A method of adding a first publisher to a security group includes receiving a key request for keys for the first publisher, wherein the key request has at least one credential associated with the first publisher and a key parameter index indicative of a bandwidth of the first publisher, includes modifying a lifetime value of the at least one key of the security group based on the key parameter index of the received key request, wherein an expiry of the at least one key is based on the lifetime value of the one or more keys; and includes transmitting the at least one key and the modified lifetime value of the at least one key to the first publisher, where the first publisher is configured to publish at least one message encrypted using the at least one key, prior to expiry of the at least one key.

A method for establishing a stream in a Time-Sensitive Networking (TSN) network, wherein a request message is sent by a stream subscriber to a Domain Name System (DNS) server, upon which entries are stored that each comprise a stream identifier of a first type assigned to a stream, and a stream identifier of a second type that is different from the first type and is assigned to the respective stream, and the specification of a predefined type exclusively used for, or forms these types of entries, where the request message comprises a stream identifier of the first type and the predefined type known to the at least one stream subscriber, where the stream subscriber receives a response message from the DNS server, which contains a stream identifier of the second type belonging to the stream, and where the stream subscriber logs on to the stream using the stream identifier obtained.

A control method, device, computer program and a computer-readable medium and method for data communication in an industrial network, wherein a stream is created between at least two stream subscribers, where resources are reserved on at least one node point, particularly bridges and/or switches between the at least two stream subscribers, and subsequently data is transmitted between the at least two stream subscribers, via the stream, and at least one subscriber of the stream interrupts the emittance and/or reception of data via the stream and resources that are reserved on at least one node point for the at least one subscriber of the stream are released for use for a data transmission that is lower priority than the data transmission via the stream, and where the reservation of the resources being maintained for the at least one subscriber.

A hearing aid includes a hearing aid housing and an antenna device constructed to receive and/or transmit electromagnetic waves having a predetermined wavelength lambda. The antenna device has a frame incorporated in the hearing aid housing for holding assemblies of the hearing aid and the frame has an electrically conductive structure being an integral part of the frame. A method for producing a hearing aid includes patterning a surface of the frame, applying an electrically conductive layer to the surface of the frame and incorporating the frame into the hearing aid housing.

Hearing aid and method for producing a hearing aid

A hearing aid device has an antenna device. The antenna device is configured to receive and/or transmit electromagnetic waves of a predetermined wavelength lambda. The antenna device has an energy coupling device which is configured to supply or to draw electrical energy to or from the antenna device. The antenna device has a first conductor and a second conductor, which are in energy exchange with the energy coupling device, extend away from the energy coupling device in different directions and are arranged a short distance from a third conductor. A first ohmic connection between the first conductor and the third conductor and a second ohmic connection between the second conductor and the third conductor are arranged at a predefined distance from the energy coupling device.

A device and a method trigger a vehicle occupant protection device of a motor vehicle. The device has a plurality of sensors that are disposed at a first location within the motor vehicle, and an evaluation device that is disposed at a second location within the passenger car. The plurality of signals that are assigned to the plurality of sensors are transmitted from the first location to the evaluation device via a first and a second transmission link of the device.

The electric multiple conductor system () is used for the transmission of signals in differential mode, and has two signal lines () and a shared reference line (). Each signal line () includes an attenuation or filter element () with a connection branch (), which runs between a branch node () in the respective signal line () and the reference line (). The attenuation or filter elements () of the respective signal lines () are nominally of the same size. Each connection branch () respectively includes a serial connection of a first partial branch () having a first reactive impedance () and a second partial branch () having a second reactive impedance (). The second partial branch () is a shared component of all attenuation or filter elements (). The multiple conductor system () achieves a very high level of common mode suppression.

The operation of appliances in a home network is to be made more user-friendly, for which purpose provision is made for the hearing device remote control unit to be integrated as a component in a network. This would, for example, enable warning signals triggered by the network to be provided in the hearing devices.

An antenna comprises a first antenna element, which has a first helix, and a second antenna element, which has a second helix. The first and the second antenna elements each have a feed point at an outer end of the corresponding helix and an open end at an inner end of the corresponding helix. A symmetrical helix antenna according to the invention can be integrated in a comparatively simple manner in an existing system, for example in a hearing aid. By integrating the antenna in a plastic housing, the antenna cannot be seen at all from the outside. The antenna is comparatively small in relation to conventional antennas.

In a hearing aid and method for automatically switching to a telephone mode, for automatically detecting a telephone situation for the wearer given a binaural supply, the difference between the levels of the input signals of the two hearing devices is measured and compared with at least one threshold value. If the difference in levels drops below or exceeds the threshold value, the respective hearing device is switched to the telephone mode.
