摘要:
A method for operating a four-roll calendar machine (R), according to which a plastic melt from an extrusion nozzle is homogenized first between a first and second roll (W1, W2), and then between a third and a fourth roll (W3, W4). The position of the third roll (W3) can be modified in relation to the rolls (W1) and/or (W2) even during operation, in order to regulate different operating states.

摘要:
A device for initiating and implementing a sudden vehicle deceleration, especially for emergency braking situations, the deceleration being initiated by the explosion of at least one propelling charge or explosive charge that acts on at least one component of the deceleration devices. Due to the explosion of the propelling charge or explosive charge, a piston is moved that applies pressure to the brake fluid, or an arrester is destroyed so that the stored energy of an energy-storing apparatus can be released. This device is triggered automatically with the aid of a surrounding-field sensor system when an unavoidable collision is detected based upon the objects in the surroundings of the vehicle and their movement.
摘要:
A device for generating electromagnetic oscillations in the HF range, in particular in the gigahertz range, using at least one Gunn element, in particular at least one Gunn diode. The device is designed to be attached to at least one printed-board-like electric or electronic circuit configuration, in particular an electric or electronic HF circuit configuration, having a generally planar expansion.
摘要:
The circuit device has a contact element, which electrically connects a wave guide (1) with a conductor strip (2). To avoid mechanical stresses due to thermal expansion the contact element is a pre-stressed prefabricated leaf spring having reproducible properties, which is bonded at one contacting area to the wave guide (1) or the conductor strip (2) by electrically conducting adhesive or glue, while a sliding contact is provided on the conductor strip (2) or the wave guide (1) at the other contacting area. The prefabricated leaf spring is preferably a MIGA leaf spring precisely made by UV depth lithography and multiplayer galvanic methods in a batch production process.

A device and a method for triggering at least one deceleration device and/or one output-determining actuator element of a vehicle propulsion system, in particular for automatic longitudinal vehicle regulation, a first surroundings sensing device being provided, which delivers longitudinal value-optimized measured values, a second surroundings sensing device being provided, which delivers object lateral dimension-optimized measuring values, and an analyzer device being provided, which receives the output signals of the first and second surroundings sensing devices and the measured values of the first and second surroundings sensing devices being used for object identification. The device and the method are furthermore suitable for initiating or performing vehicle deceleration for collision avoidance or for alleviating the severity of a collision.
摘要:
A method and a device for controlling automatic emergency braking of a motor vehicle to reduce the severity of a collision of a vehicle with an object, the position and/or speed of the object with respect to the host vehicle being determined via an object detection device, and this information being sent to a collision detection device which ascertains whether a collision with an object is imminent and, on detecting a collision, triggers emergency braking and ascertains a collision instant, emergency braking being terminated after the period of time until the determined collision instant has elapsed.
