Abstract: The invention relates to a collision-warning device for motor vehicles, in particular for avoiding collisions with standing obstacles in the proximity of a motor vehicle having a distance measuring device for contactless distance and position detection of an object in the proximity of a motor vehicle, which distance measuring device emits corresponding distance signals (line 27) and position signals (line 29). According to the invention, at least one sensor (30, 31) is provided for detecting a travel course corresponding to a specific operating state present at the time, said sensor emitting corresponding movement signals (lines 32, 33). The distance and position signals as well as the movement signals are fed to an evaluation unit (24) which, on the basis of these signals and taking into account the vehicle-specific conditions, calculates whether there is a collision course with a detected object. If this is the case, this is reported to the driver by means of a connected indicator unit (loudspeaker 25). <IMAGE>

Abstract: An image pickup device is capable of picking up images while electrically enlarging the same. In enlarging image pickup, horizontal transfer pulses H₁, H₂, a reset pulse R, a clock signal CLK, sampling pulses SP₁, SP₂ and so on having the periods two time as long as those in the normal image pickup are generated from a horizontal transferring circuit (200) in a timing pulse generating circuit (2), whereby charges stored in a CCD image sensor (6) are horizontally transferred by these signals. A vertical transfer circuit (250) sets vertical transfer pulses V₁ to V₄ at arbitrary timings during 1H of a video period to output the same once in every 2H and outputs high speed vertical transfer pulses in two periods in a vertical blanking period, outputs a reading pulse TG between the first high speed vertical transfer period and the next high speed vertical transfer period, and the charges stored in the CCD image sensor are transferred in the vertical direction in response to these signals. Consequently, an arbitrary area of the screen of the normal image pickup can be enlarged to be picked up.

Abstract: A real time soil chemical sensor and precision agricultural chemical delivery system includes a plurality of ground-engaging tools in association with individual soil sensors which measure soil chemical levels. The system includes the addition of a solvent which rapidly saturates the soil/tool interface to form a conductive solution of chemicals leached from the soil. A multivalent electrode, positioned within a multivalent frame of the ground-engaging tool, applies a voltage or impresses a current between the electrode and the tool frame. A real-time soil chemical sensor and controller senses the electrochemical reaction resulting from the application of the voltage or current to the leachate, measures it by resistivity methods, and compares it against pre-set resistivity levels for substances leached by the solvent. Still greater precision is obtained by calibrating for the second current impressed through solventless soil. The appropriate concentration is then found and the servo-controlled delivery system applies the appropriate amount of fertilizer or agricultural chemicals substantially in the location from which the soil measurement was taken.

Abstract: In the method for reducing the nitrogen oxide formation in the combustion of fossil fuels in a combustion chamber, flue gases are, after preceding removal of heat, recycled to the burner side of the combustion chamber and, due to the injector action of the flame, introduced around the burner into the combustion space in a part quantity reducing the combustion temperature to a temperature level which is at most equal to the limiting temperature for the formation of nitrogen oxides. As a result, the flame is surrounded by  - cool - flue gases and cooled. In a firing installation, a combustion chamber arranged within a housing carrying a flow of a heat carrier medium has a "hot" combustion space which is surrounded by a shell accommodated at a distance from the combustion chamber walls. Flue gas flow paths extend between the shell and the combustion chamber, and at least one inflow path branches off from these for recycling a part stream of the - cooled - flue gas into the combustion space, this path leading into the latter in the vicinity of a burner or flame tube and cooling the combustion flame. <IMAGE>

Abstract: An odor-absorbing, non-dusting porous material and a method of making the same. The web material includes a porous base web (for example, a fibrous base web, such as a non-woven or paper web) having distributed throughout odor-absorbing particulate (such as zeolite). Alkaline salt or alkaline earth oxide particulate, to better effect removal of acidic malodor, desirably also is distributed throughout the base web, in the final product. The odor-absorbing particulate is bound to the base web (e.g., fibers of a fibrous base web) by a binding system, containing a binding agent. The binding system, in the odor-absorbing web materials, is transparent to the odors so as not to substantially effect the ability of the particulate to absorb odor-causing material. The odor-absorbing web material is formed by dipping a porous base web in a saturant slurry containing the odor-absorbing particulate (the slurry including an alkaline salt or alakaline earth oxide) and the binding agent, together with a surfactant; squeezing out excess saturant slurry from the web; and drying. Also disclosed are the saturant slurry and two specific uses of the odor-absorbing web material: (1) in personal care products such as catamenial devices and (2) in packages containing medical materials such as hospital gowns, which materials have been sterilized in the sealed package by gamma sterilization.

Abstract: The depth of modulation of an analog electrical signal generated by a photodetector during scanning of a bar code symbol in the field of bar code scanning is enhanced under circumstances where the modulation of the analog signal has been degraded, for example, by an oversized sampling aperture in relation to the widths of the symbol elements. The anaiog signal has high frequency components whose low amplitudes are increased in magnitude prior to being conducted to a digitizer. The effect of noise introduced during reading of the bar code is cancelled by comparing in the comparator, the modulation-enhanced analog signal with the second derivative signal derived from the modulation-degraded unenhanced analog signai. The output of the comparator is a digital output signai having a logical levei dependent on the amplitude of the enhanced analog signai at each zero crossing of the second derivative signal. The digital output signal is a closer representation of the code read by the scanner.
