摘要:
In conventional aircraft cargo compartments panels or similar flat floor elements are fastened to floor beams or similar supporting elements that are installed in the body of the aircraft. Subsequently functional units such as roller elements latches or PDUs are mounted and connected to one another by way of appropriate control conductors. In the present invention it is proposed to fasten the floor elements permanently to the supporting beams so as to form prefabricated floor modules and to install these floor modules in the aircraft.

A device for detecting at least one substance of a fluid, has a piezoacoustic thin film resonator with a piezoelectric layer on which electrode layers are arranged, and an adsorption surface for adsorbing the fluid substance, wherein the piezoelectric and electrode layers and the adsorption surface are designed and arranged on each other such that by electrically activating the electrode layers, an excitation alternating field can be coupled into the piezoelectric layer. The thin film resonator can be excited to a resonance oscillation frequency fR which depends on an amount of the substance adsorbed on the adsorption surface because of an excitation alternating field coupled into the piezoelectric layer. An electrical insulating layer is arranged directly on a side of one of the electrode layers facing away from the piezoelectric layer. Particularly advantageous is the combination of an aluminum electrode layer and a silicon dioxide insulating layer.

A method of modifying radar, thermal, acoustic, and visual signatures of an object includes the application of flocking to the object. The flocking may be applied by an electrostatic flocking process. The flocking material may be constructed to include a radar absorbent material to increase the efficacy of the flocking material relative to the reduction and alteration of radar signature screening.

Methods for rapidly obtaining a nanoscale apolipoprotein bound phospholipid bilayer (NABB) associated with at least one membrane protein are provided. Also disclosed are methods for rapidly obtaining a NABB not associated with membrane proteins. Immunogenic compositions comprising NABBs with native conformational epitopes are also provided along with their methods of use.

In a method for influencing the traction force during shifting operations of a manual transmission in vehicles having at least two drive axles, the drive system of the first axle is activated in such a way that the interruptions in traction force occurring at the second axle during shifting operations of the manual transmission are at least partially compensated for.

A floor module with roller conveyors which define an aircraft cargo hold floor with a loading level is provided. The floor modules have cross-members to which the roller conveyor is attached. A rail with two side pieces is provided, between which rollers are rotatably mounted in such a way that they protrude above upper edges of the rails. The side pieces are joined to one another by a floor section. To improve the strength of the floor module, the floor section has a bent region inclined in cross-section at an angle to the loading level, the bent region dividing the floor section into one partial section lying higher and one partial section lying lower relative to the upper edges.

A material composite has at least one region of copper or a copper alloy, at least one region of a predominantly graphitic material, and at least one boundary region between them. The boundary region has one or more carbides from the group of the IVb, Vb, VIb transition metals and one or more elements of the group consisting of Si, B, Al, Ge, Mn, Sn. In a preferred implementation of the invention, the composite is produced with a back-casting process.

In a method for controlling a generation of an alternating current in a vehicle equipped with a battery and an inverter, the inverter is electrically connectable to the battery in order to generate an alternating current from a direct current of the battery for electrical devices that are electrically connectable to the inverter, and the battery is recharged when a charging state of the battery is equal to or less than a threshold value that is sufficient to generate an alternating current required for the electrical devices.

A transmitting device, a receiving device, and a method for transmitting and a method for receiving data streams, in particular video streams, are described. The transmitting device for data streams, in particular video data, has at least one unit. This at least one unit is designed for subdividing the data streams into sections, the sections into packets, and for providing the sections in a sequence that is the reverse of an original sequence and the packets in an original sequence.
摘要:
A device for monitoring a processor is described. A watchdog simultaneously monitors the system clock, the software base functions and performs a check of the tests of the system components of the processor. If an error is detected, the watchdog communicates this to the processor, an error counter is incremented and at least one device that is connected to the processor is blocked. If the error counter attains a predetermined value, the block is continued until the device of the present invention is deactivated. If an additional error is detected during a blocking time, the blocking time is extended.
