摘要： A trigger circuit for occupant protection systems in motor vehicles comprises a control unit which will effect the triggering of a means of restraint such as an airbag, depending on sensor signals generated by one or more external sensor units. To achieve a degree of triggering certainty, data interrogation must take place in very short time intervals. A safe transmission of data between the control unit and the sensor units will be ensured if, in accordance with this invention, the information units to be transmitted will each be encoded by means of a PWM signal with a certain period duration. The control unit will check the period duration of the PWM signal received, and, in the event of this actual period duration not matching the specified nominal value, it will not accept the relevant unit of information.

摘要： A data transmission method in a real-time data processing system, comprising a control unit and at least one function unit linked to this control unit through a data line, is described that permits noise-free and noise-insensitive transmission of data. In accordance with the invention, the data is stored in a buffer memory made up of a shift register and an intermediate storage, before being loaded into a main memory of the function unit. Transfer to the intermediate storage takes place only if certain conditions are satisfied that identify transmission faults. Before the data is stored in the main memory, the data is read-back into the control unit memory for the purposes of checking and there it is compared with the original data. If there is no correspondence, data transmission is performed again. The method in accordance with the invention can be applied advantageously in local networks, and in particular for motor vehicles, where a central control unit is applied for controlling operational sequences through various function units such as triggering circuits for passenger restraint systems or control circuits concerning motor management.

摘要： Increasingly, motor vehicles are being equipped with safety systems for vehicle occupants and where these safety systems are controlled by electrically actuated triggering means such as ignition pills for airbags that in turn are controlled from an output stage. The invention demonstrates a method that ensures safe and uninterrupted operation of these triggering means and which protects the output stage from being destroyed should a fault occur as a result of, for example, an ignition pill by-pass.

摘要： To trigger driver and passenger airbags as well as side airbags, the sensor signals generated by collision sensors will be fed into a central control unit for processing. According to this invention, side airbags will be activated by evaluating sensor signals generated by a collision sensor for detecting head-on and side collisions, centrally located within the motor vehicle, as well as by a left-hand and right-hand collision sensor each detecting side collisions, by the control unit generating a triggering signal whenever the centrally located collision sensor and at least one of the two side collision sensors generate a collision signal, with one of these two collision sensors having a greater value, or if the centrally located collision sensor as well as one of the two side collision sensors provide a signal of equal value, with the other side collision sensor simultaneously generating a collision signal with a value either equal or lower than the value of the collision signal generated by the central collision sensor. The process according to this invention will lead to a very high degree of triggering certainty for the entire occupant protection system, and advantageously does not require the use of a mechanical safety switch to trigger the side airbags.

摘要： An arrangement for supplying electrical power to at least one load arranged along a power supply line, preferably in motor vehicles, is characterized by having a power supply facility that has at least one input for a supply voltage and at least one output for the supply voltage and a testing device, by the testing device being designed to test an output for the supply voltage to establish whether a short-circuit, i.e. a resistance of too low a value, exists at this output, and by the power supply facility having a switching device and being designed in such a way that a supply voltage fed to it is switched through by the switching device to the output tested by the testing device only when the test has established the non-existence of a short-circuit. This allows the power supply to be maintained if a single fault occurs.

摘要： An ignition circuit output stage which is driven by one or several microprocessors. Up to now different modes of operation each required their own different ignition circuit output stage. The ignition circuit output stage according to the invention is programmable - that is, using one and the same output stage, different modes of operation can be selected such as, for example, the unregulated or output stage mode as well as the regulated and limited output current mode. The circuit essentially consists of a down converter which, when activated, will regulate and limit the discharge current. The down converter can be activated and deactivated by means of an appropriate signal. When the down converter is in its deactivated state, an unregulated discharge takes place; this is the output stage mode. With the programmable output stage it is possible to select the best mode of operation for the relevant application case--such as, for example, operation without inductance as well as energy supplied directly from the onboard battery--without different output stage ICs being required.

摘要： The invention concerns aircraft propellers of the variable pitch type. Each propeller blade is carried by a trunnion which is rotatably mounted to a common ring. Each trunnion contains a reduction gear set which is driven by a radial shaft. The reduction gear sets multiply the torque applied by the shafts, thus allowing shafts of reduced diameter to be used. The reduced diameter is important when the shafts must pass through a turbine flowpath, and thus be concealed within turbine blades. The reduced diameter shafts can be easily concealed within turbine blades without redesigning and compromising blade aerodynamics.

摘要： In the case of a data transmission system for the exchange of digital data between a central processor unit and several peripheral control modules which are connected to the former by a bus system such that communication is enabled and which are provided for the purpose of activating one each, respectively, out of several safety devices such as airbags or belt tensioning systems, or similar devices, in a motor vehicle, and wherein these peripheral control modules are each provided with one buffer capacitor whose energy content is sufficient for operating the respective module, and the device driven by this module, within specifications over a limited period of time, the bus system is designed as a single wire system for the purpose of achieving a simple setup and reducing installation and fitting costs. In this single wire system the control modules are supplied with electrical operating energy, and digital data are transmintted, by the same line sections. In the data communications mode of the central processor unit and the control modules, the energy supply of the modules is effected by their buffer capacitors. The transmission of the digital data from the central processor unit to the control modules as well as the passing on of such data is effected by modulating a direct voltage whose maximum level U.sub.S is significantly lower than the maximum voltage level U.sub.B up to which the buffer capacitors can be recharged. The recharging of the buffer capacitors is effected in charge mode periods nested in between transmission operation phases of the central processor unit and the peripheral control modules.
