Abstract: A feeding apparatus for poultry is disclosed, and comprises a feed source, a feed line formed at the feed source, a feed valve mechanism arranged in the feed line and which in a closed valve position blocks feed from passing through the feed line and in an open valve position allows feed to pass through the feed line. The feeding apparatus has a pecking block which is moveably mounted and mechanically coupled to the feed valve mechanism in such a way that the feed valve mechanism is closed when the pecking block is in a neutral position and the feed valve mechanism is open when the pecking block is in a deflected position due to pecking at the pecking block.

Abstract: The invention relates to an activity device for use in poultry management and/or rearing, an activity system, an animal house, in particular for rearing and/or managing poultry, and a method of rearing and/or managing poultry. The present invention relates in particular to an activity device for use in poultry management and/or rearing comprising a material container with at least one material inlet, and at least one pecking opening, a pecking pan for receiving pecking material comprising at least one abrasion section having an abrasion enhancing surface, wherein the material container is arranged and designed to guide pecking material from the material inlet to the pecking opening, and wherein the pecking opening is arranged and designed in such a way that pecking material in the material container is prevented from falling out of the pecking opening due to gravity.

Abstract: Method for detecting a defective node which is connected to a bus, the node incrementing an internal error counter in a normal operating state when an error is detected, and the node switching to an isolated operating state, in which the node does not exchange any messages via the bus if the internal error counter of the node exceeds a predetermined error threshold value, and the node switching from the isolated operating state to the normal operating state when a condition is fulfilled and that change in state being detected, and the node being detected as being defective if a rate of the detected state changes exceeds an adjustable change rate or a number of detected state changes exceeds an adjustable state change threshold value.

Abstract: A system for air-conditioning an aircraft cabin includes an air conditioning unit connected to a central mixer, a first recirculation system designed to remove exhaust air from a first aircraft cabin region and connected to the central mixer, and a second recirculation system designed to remove exhaust air from a second aircraft cabin region and connected to a local mixer. A control device is designed to control the second recirculation system to reduce an air volume flow being removed from the second aircraft cabin region when shifting from a first operating state (e.g., normal operation) to a second operating state (e.g., defined operating situations such as when quick cooling is desired). The air volume being removed from the first aircraft cabin region may be increased accordingly in the second operating state.

Abstract: A system (10) for air-conditioning an aircraft cabin (12) comprises an air conditioning unit (14) connected to a central mixer (16) in order to supply the central mixer (16) with air at a desired low temperature. A first recirculation system (18) is designed to remove exhaust air from a first aircraft cabin region (12a) and is connected to the central mixer (16) in order to lead the exhaust air from the first aircraft cabin region (12a) into the central mixer (16). A second recirculation system (24) is designed to remove exhaust air from a second aircraft cabin region (12b) and is connected to a local mixer (20, 22) in order to lead the exhaust air from the second aircraft cabin (12b) into the local mixer (20, 22). The local mixer (20, 22) is connected to the central mixer (16) in order to supply mixed air from the central mixer (16) into the local mixer (20, 22).

Abstract: A system (10) for conveying recirculation air from an aircraft cabin comprises a plurality of conveying devices (12a-12j) which are arranged in a manner distributed along an aircraft cabin region (14). A control device (16) is configured to control the conveying devices (12a-12j) in the normal operation of the system (10) in such a manner that each conveying device (12a-12j) removes a predetermined air volume flow from the aircraft cabin region (14). The control device (16) is furthermore configured to control, in the event of a failure of a conveying device (12c), at least some of the remaining still functional conveying devices (12a, 12b, 12d-12j) in such a manner that the entire air volume flow removed from the aircraft cabin region (14) by the remaining still functional conveying devices (12a, 12b, 12d-12j) is increased by an amount corresponding to an air volume flow amount removed from the aircraft cabin region (14) by the failed conveying device (12c) in the normal operation of the system (10).
