Abstract: This disclosure describes at least embodiments of an aircraft monitoring system for an electric or hybrid airplane. The aircraft monitoring system can be constructed to enable the electric or hybrid aircraft to pass certification requirements relating to a safety risk analysis. The aircraft monitoring system can have different subsystems for monitoring and alerting of failures of a component, such as a battery pack, a motor controller, and/or a motors. The failures that pose a greater safety risk may be monitored and indicated by one or more subsystems without use of programmable components.

Abstract: A blower spray device is provided having a housing which comprises an electrically driven blower and a spray nozzle, and having a liquid supply line opening into the spray nozzle. The housing has a funnel-shaped intake channel and a tubular blow-out channel, and an electrical valve is provided in the liquid supply line to activate and deactivate the liquid supply to the spray nozzle. An electronic controller having a regulating unit for the electric blower is further provided to adjust the air flow velocity.

Abstract: A battery module can include multiple cell tubes, a first conductive plate, and multiple first spacers. The multiple cell tubes can accommodate multiple battery cells within the multiple cell tubes so that individual of the multiple battery cells are positioned within individual of the multiple cell tubes. The first conductive plate can include multiple first holes and electrically connect first terminals of the multiple cells. The multiple first spacers can be mounted in the multiple first holes and support the multiple tubes and the multiple cells with respect to the first conductive plate, the multiple first spacers being configured to provide thermal and electrical isolation between the multiple battery cells and the first conductive plate.

Abstract: A system for preparing milk and milk foam in drink machines, such as coffee machines and similar pieces of equipment, which are provided with a heater unit for heating the milk and/or the milk foam with steam, contains a feed for the milk and/or the milk foam and a separate feed for the steam, which is fed directly, as a heat-transfer medium, into the milk and/or the milk foam in the heater unit, which operates as an injector.

Abstract: The invention relates to a cleaning system for coffee machines, comprising a cleaning device for periodically cleaning the coffee- and/or milk-carrying components using a cleaning liquid, which contains cleaning agent in the form of balls or tablets dissolved therein, wherein the cleaning device is provided with a time- and/or product-cycle-dependent controller and a metering apparatus (1) for the cleaning agent (10) that interacts with the controller. Thus, it is possible to program the cleaning process in a customized manner according to the mode of operation and to carry out the cleaning process fully automatically according to the program. The metering of the cleaning agent (10) according to the program ensures an always optimal cleaning effect together with sparing use of cleaning agents. Simple and safe handling is achieved by using ball- or tablet-shaped cleaning agents.

Abstract: The invention relates to a system for preparing milk and milk foam in drinks machines, such as coffee machines and similar pieces of equipment, which are provided with a heater unit for heating the milk and/or the milk foam with steam. The system contains, according to the invention, a feed for the milk and/or the milk foam and a separate feed for the steam, which is fed directly, as a heat-transfer medium, into the milk and/or the milk foam in the heater unit, which operates as an injector. The system allows a high heating capacity along with simultaneously good regulating capability and minimized thermal inertia. Since the foaming operation and the heating operation are separated from one another, the quality of the milk foam remains unimpaired by the heating operation.
