Abstract: There is provided a method of providing assistive listening to a user of an audio receiver device, comprising: detecting, by a Broadcast Assistant device, proximity of the Broadcast Assistant device to a synchronizer device, and receiving, by the Broadcast Assistant device via a wireless protocol different from a Bluetooth protocol, information required for identifying an audio source device from a synchronizer device upon detection of proximity to the synchronizer device, retrieving, by the Broadcast Assistant device, via a wireless protocol different from the Bluetooth protocol, synchronization information required for synchronizing the audio receiver device to the audio source device to receive an Auracast stream; synchronizing, by the Broadcast Assistant device, to an Auracast periodic advertising of the audio source device; providing, by the Broadcast Assistant device, the synchronization information to the audio receiver device; and synchronizing the audio receiver device to the audio source device.

Abstract: A sample changer for a balance (1) with a weighing pan (18) has at least two sample carriers (3) that are spaced apart from each other. Each sample carrier is configured to receive at least one weighing-object unit and transport the weighing-object unit to the weighing pan (18). An individual draft-shield element (4) consisting at least in part of a transparent material is arranged above each of the sample carriers (3), closing off a sample space laterally and from above.
