摘要:
An electronically commutated electric motor includes a stator and a rotor formed as a permanent magnet. A control unit is connected to the stator and configured to energize the stator to produce a rotating magnetic field. The electric motor further includes at least one Hall sensor configured to detect at least a magnitude of a sensor magnetic field produced by a sensor magnet connected to the rotor. The electric motor also includes at least one magneto resistive sensor configured to detect an alignment of a total magnetic field during a rotor revolution of the rotor and to generate a rotor position signal representing this alignment. The total magnetic field includes the sensor magnetic field and an interference magnetic field superimposed thereon. The control unit is further configured to determine the rotor position of the rotor at least depending on the alignment of the total magnetic field.

摘要:
A device for the electrical and mechanical connection of a first, preferably elastically flexible printed circuit board to a second printed circuit board wherein an electrically conductive contact pin, protruding from the second printed circuit board and projecting through an opening in the first printed circuit board, is electrically conductively connected to a conductor track of the first printed circuit board. The device further includes an electrically conductive clamping part with elastically flexible protrusions embodied on it that embrace the contact pin by nonpositive engagement, and a bearing region of the clamping part that is electrically connected to the protrusions is pressed in prestressed fashion against a conductor track disposed on the first printed circuit board.

Passenger service units in an aircraft are equipped with a passenger interface and supply adapter (10). Each adapter includes an individual processor (14) which is programmable independently of the aircraft central control through a programming input. The programmable interface (10) permits controlling passenger service components in the passenger cabin such as lamps in a cabin lighting system, a public address system, and so forth, directly by the interface (10) independently of the aircraft central control. The interface (10) with its own individual processor (14) and memory (15) is connected through a databus (11) to the aircraft central control (12), for example, for remote programming of the interface and for reporting the module's activities to the aircraft central control. The interface (10) reduces the memory capacity requirements for the aircraft central control and permits the individual programming of each passenger service unit also independently of any other passenger service unit thereby avoiding retesting of the entire cabin system when for example only one passenger service unit is reprogrammed.

A discharge lamp assembly has a discharge lamp, and an ignition device for the discharge lamp, the ignition device including at least one inductive component and at least one capacitive component, at least a part of one of the components being surrounded by at least a part of the other of the components, the ignition device further having a housing in which the components are arranged and which is connectable with the discharge lamp.
摘要:
A display module for displaying passenger-specific display information in an aircraft, comprising: a display, a control unit, a storage device, and a first interface, wherein the first interface is connected to the control unit, and wherein the control unit is designed, on the basis of a signal that is present at the first interface, to read out a storage device content stored in the storage device and associated with the signal in relation to display information, and on the basis of the read-out storage device content and of the signal present at the interface to control the display.
摘要:
Integration of supply functions is provided in a storage compartment. In particular, an integrated module is provided, which can be mounted in the overhead area of a passenger cabin, and exhibits different system components, which are automatically hooked up to the supply system of the transport (e.g., an aircraft) during the mechanical installation of the module on the load-bearing structure of the cabin.
摘要:
A user interface for monitoring and controlling a plurality of aircraft cabin systems includes a liquid crystal display screen (LCD) having a touch sensitive input surface including a plurality of touch sensitive input keys. Each key is labeled with a symbol identifying a respective one of the plurality of aircraft cabin systems. First and second system menus corresponding to first and second systems of the plurality of aircraft cabin systems are displayable on the LCD as first and second system graphical menus when a key identifying the appropriate system is activated by the user. The graphical menus include status information and operating functions as well as an input area that provides selection and control of the operating functions of the respective system when touched by the user.
摘要:
A monitoring and control device includes a touch sensitive LCD screen, with a basic layout including a display area and touch sensitive keys depicted with associated system and function symbols. A main menu or any one of plural system menus can be selectively displayed in the display area. The system menus relate to cabin systems such as audio, lighting, and water systems. The selected system menu displays status information and touch input keys for the user to monitor the status and to select and control the operation of the system. The main menu is a top level window providing essential information regarding all of the cabin systems and allows a user to select any one of the system menus. The device is compact, user-friendly, and adaptable to various system requirements by mere software reprogramming. The displays and input keys are all virtual elements generated by software.
