摘要:
Laser-induced color printing with means with which the printing color of a micro-capsule to be impinged by the laser beam (12) is identified. These means are a fluorescence transformer material as a constituent of the content of the micro-capsules (3) or an additional white light ray with which the printing color of an individual micro-capsule (3) can likewise be identified.The printing ensues given coincidence of a printing instruction provided for a defined location with color specification and of the momentary incidence of the scanning laser beam (12) on a micro-capsule (3) for which this printing color has been identified as being present.
摘要:
A pyrodetector, which is both movement selective and directional selective, has preferably a foil supporting detector elements relative to a concave mirror which may have a spherical curve surface, a spherical-parabolic curve surface or a curve surface between a spherical surface and a spherical-parabolic surface. The sensor is preferably a plurality of individual sensor elements which are arranged on an arc, preferably on a planar member or a foil, and may include additional or second sensor elements having electrodes which are for determining temperature compensation for the detector.

With the present tank ventilation system formed of a fuel tank, an active carbon filter, a control unit, a lambda probe, a tank ventilation valve and a flow sensor it is possible to recognize defects at the connecting lines and the ventilation valve immediately. For the recognition of the defect, a control unit is provided which examines the signals arriving from the lambda probe and from the flow sensor along with the outgoing tank ventilation control signals for unreasonable events. When a defect is recognized, the error signal is stored. A ceramic PTC resistor is preferably employed as the flow sensor.

Optical sensor line of amorphous or polycrystalline photo-electric material having a plurality of sensor elements. An optical sensor line of amorphous or polycrystalline photo-electric material having a plurality of sensor elements, whereby it is provided that a non-linear element is allocated to each sensor element as a converter that converts the photo-current (i.sub.ph) of the associated sensor and which is proportional to the quantity of light incident on the sensor into a signal voltage (u.sub.s) that is at least approximately proportional to the logarithm of the photo-current (i.sub.ph).

A device for detecting a collision with a vehicle includes a pressure sensor for detecting compression of a substantially closed measuring volume upon collision. The measuring volume is arranged along a part of the vehicle body that is impacted during the collision. The cross-sectional area of the measuring volume, along its longitudinal direction, has a comparatively larger area in the vicinity of those parts of the vehicle body that are comparatively rigid and therefore comparatively difficult to deform during collision.
摘要:
A configuration for controlling an occupant restraint device of a motor vehicle. The occupant restraint device is activated only whenever it is ascertained, by an evaluator, that simultaneously a signal of a first acceleration sensor and a signal of a second acceleration sensor indicate a collision. The sensitivity axes of the acceleration sensors are oriented differently.

A control assembly for a passenger protection system of a vehicle which is tripped upon the occurrence of a side impact traffic accident. The control assembly has at least one detector adapted to detect a pressure rise in a hollow body. The at least one detector is mounted in a largely enclosed side portion on the side of the vehicle body defining a hollow body such as a door. A control unit is connected to and receives signals from the at least one detector. The control unit evaluates a sudden and largely adiabatic air pressure rise detected by the detector upon a side impact collision and determines whether to actuate a passenger protection system such as an air bag.

The invention relates to the idea of not initially multiplying the output signal (a) of an acceleration sensor (19) with regard to a weighted sum (Σg) with a correction factor (kw) but to alter a test signal (t) by using a weighting means (16) in such a manner that an already weighted output signal (ag) can be generated so that during a test operation, the safing algorithm of an evaluating device can be directly fallen back upon, whereby this can be advantageously tested with regard to its ability to operate. The invention is particularly suited for occupant protection systems of a modern motor vehicle.
摘要:
In a control configuration for an occupant protection system for side collision protection in a vehicle, an enable signal of a protection configuration generated as a function of transverse acceleration, is delivered to a timer. The timer furnishes an enable signal of a fixed minimum duration for triggering the occupant protection system.
摘要:
A micromechanical sensor unit for detecting acceleration has pendulums each with a spiral spring and a seismic mass. Supports each being connected to a respective one of the pendulums, and position sensors, each two of the position sensors is associated with a respective one of the pendulums. Each position sensor and an associated pendulum form a switch with a defined triggering threshold and at least two switches respond to the same direction of acceleration. At least one switch is a safing sensor with a separate tap of a sensor signal.
