Abstract: A headset has earmuffs connected by a connection element. The earmuffs have inner sides facing each other and outer sides facing away from each other in a first transverse direction. The earmuffs extend from a bottom side to a top side in a vertical direction. The earmuffs extend from a first to a second longitudinal side in a second transverse direction. At least one of the earmuffs has a positioning pocket at the outer side with a button arranged therein. The positioning pocket extends across a width in second transverse direction that corresponds to at least 50% of a width of the at least one of the earmuffs. The positioning pocket has a bottom end and a top end and extends in vertical direction from the bottom end to the top end. The top end of the positioning pocket forms a stop edge for fingertips of an operator's hand.

Abstract: A method for determining information (Info) about a state (Z) of a drive motor system (2) and/or of a drive battery pack (11) of a gardening, forestry and/or construction device (1), includes the steps of: acquiring at least one sensor temperature (TS) of at least one temperature component (3) of the drive motor system (2) and/or of the drive battery pack (11) by way of at least one component temperature sensor (4) at the same time as and/or at a time after operation of the drive motor system (2) and/or of the drive battery pack (11) and/or of a heater (300) and/or of a cooler (310) and/or of a fan (320) for heating and/or for cooling the drive battery pack (11), wherein the temperature component (3) heats up or cools down due to the operation; ascertaining operating data (BD) of the operation, wherein the operating data (BD) are of a different kind than the sensor temperature (TS); comparing the acquired sensor temperature (TS) or a variable based on the sensor temperature and the ascertained operating data

Abstract: A method operates a forest communication system having multiple mobile communication apparatus, the communication apparatus each including an output and input device. The output and input device is designed for the output and input of work process data relevant to one member in a working group about work steps on tree sections that are to be worked on and/or have been worked on. The method reconciles the work process data between the communication apparatus in a peer-to-peer network by way of wireless transmission on the basis of a medium-range transmission technology.
