Abstract: A method automatically monitors a working and/or storage environment of at least one mobile component of a gardening, forestry, construction, ground-processing and/or transport system that includes at least one motor-powered gardening, forestry, construction, ground-processing and/or mobile transport device. The component has a temperature sensor designed to detect a temperature of the working and/or storage environment. The method a) detects the temperature using the temperature sensor, and b) if a set of ambient fire criteria is met, wherein the set of ambient fire criteria is characteristic of a fire in the working and/or storage environment and includes at least one fire temperature criterion, wherein the fire temperature criterion is to be met by the detected temperature or a quantity based on the detected temperature, outputs and/or transmits an ambient fire alarm signal to a fire alarm system.

Abstract: A housing has a communication module arranged in a housing body. Electrical contacts are provided under a closure cover of the housing and are electrically connected to electrical components arranged in the housing body. The communication module is placed on the electrical contacts and is fixed in position in a receptacle fixed to the housing body. Contact elements of the communication module are in electrical contact with the electrical contacts in the housing body. The communication module is pressed onto the electrical contacts by at least one pressure element, with the pressure element being arranged between the closure cover and the communication module.

Abstract: A battery pack has a plurality of pack power contacts, the pack power contacts having touch points for the user-releasable touching of tool power contacts of an electrically powered tool for supplying the tool with electric drive power from the battery pack, and a pack housing. The pack housing has at least one flame-retardant housing component and at least one impact-protection housing component. The at least one flame-retardant housing component has at least one flame-retardant material acting as a flame retardant for the battery pack. The least one impact-protection housing component has at least one impact-protection material that differs from the flame-retardant material for providing impact protection for the battery pack. The touch points are located in the region of the at least one flame-retardant housing component and not in the region of the at least one impact-protection housing component.

Abstract: A cordless device includes a battery bay, a guiding web of a first type and a guiding web of a second type, different than the guiding web of the first type. The battery bay is designed for the exchangeable reception of a battery pack. The guiding web of the first type is designed for touching the battery pack in at least one guiding groove of the battery pack on at least one circumferential side of the battery pack for the guided positioning of the battery pack in a first direction in the battery bay. The guiding web of the second type is designed for touching the battery pack on at least one circumferential surface of the battery pack on at least the same circumferential side of the battery pack for the guided positioning of the battery pack in a second direction, different from the first direction, in the battery bay.
