摘要:
A method for assisting the driver of a vehicle (10) during a driving maneuver such as, for example, a parking or positioning maneuver. In such a case, a reference trajectory (16) along which the vehicle (10) is to be moved is determined. A steering wheel position which is to be set and which steers the vehicle along the reference trajectory (16) is indicated to the driver during the driving maneuver. A steering angle deviation between the actual steering angle which is actually set by the driver and the setpoint steering angle which corresponds to the requested steering wheel position is corrected independently of the driver.

1. Method and device for assisting the driver of a vehicle during a parking maneuver. 2.1. Known devices for assisting the driver of a vehicle during the execution of a parking maneuver usually comprise surroundings-sensing means for sensing and measuring potential parking gaps, means for determining a parking strategy and information means for outputting instructions to the driver, which instructions guide him into the parking gap. The new method and the new device are intended to provide the driver with better assistance during the execution of the parking maneuver. 2.2. For this purpose, a parking situation image on which the parking gap, an optimum setpoint position and a first and second vehicle are represented in a plan view is displayed to the driver on an image display device. In this context, the optimum setpoint position corresponds to a position which the vehicle is intended to assume within the parking gap, the first vehicle corresponds to the vehicle in its instantaneous position and the second vehicle corresponds to the vehicle in an expected target position which can be varied by means of the steering angle.

In a method and a measuring device for metal detection with the use of a coil arrangement the spatially offset transmitting coils are controlled with pulse sequences of different pulse patterns. The receiving coils associated with the transmitting coils are scanned with respect to the received measuring signals with a scan pattern corresponding to the respective associated pulse pattern. It is therefore possible to control simultaneously all transmitting coils and to provide a spatial determination of a metal object located in a throughgoing region of a gate frame.

The composition for oxidative dyeing of hair contains 0.01 to 5.0 percent by weight of at least one 5-aminophenol compound of the formula ##STR1## wherein R is an alkyl group having 1 to 4 carbon atoms, X is fluorine or OR.sup.1 and R.sup.1 is an alkyl group having 2 to 4 carbon atoms, a monohydroxyalkyl group with 2 to 4 carbon atoms or a dihydroxyalkyl group with 3 and 4 carbon atoms, and physiologically tolerated water-soluble salts thereof as coupler substance; and 0.1 to 6.1 percent by weight of a total amount of the coupler substance and at least one developer substance. The developer substance can be 1,4-diaminobenzene, 2,5-diaminotoluene, 2,5-diaminobenzyl alcohol, 2-(2'-hydroxyethyl)-1,4-diaminobenzene, 4-aminophenol, 4-amino-3-methylphenol, 4-amino-2-methoxymethylphenol, 4-amino-2-ethoxy-methylphenol and tetraaminophyrimidine and physiologically tolerated water-soluble salts thereof. The invention also concerns certain new substituted 2-alkyl-5-aminophenols including 5-amino-4-ethoxy-2-methylphenol, 5-amino-4-(2'-hydroxyethyl)oxy-2-methylphenol and 5-amino-2-ethyl-4-fluorophenol.

A plurality of luminescent elements, such as light-emitting diodes, incandescent lamps or the like, are located adjacent each other, each connected to the output of a difference amplifier. The respective inputs of the difference amplifier are connected, on the one hand, to a voltage divider to have different reference voltages applied thereto and, on the other, in common to the input voltage to be sampled so that, as the voltage changes between the amplification ranges of the difference amplifiers, the output therefrom will change in accordance with input voltage so that the brightness of the respectively connected luminescent elements will also change, thus providing gradual increase in brightness of any individual element as the voltage changes. The difference amplifiers may be differentially connected operational amplifiers.

The oxidation hair dye composition is based on a combination of coupler substance and developer substance, and includes, as developer substance, at least one 2,5-diaminobenzonitrile compound of the formula (I), ##STR1## in which R.sup.1 and R.sup.2, independently of each other, are selected from the group consisting of H, alkyl groups having 1 to 6 carbon atoms, hydroxyalkyl groups having 2 to 4 carbon atoms and dihydroxyalkyl groups having 3 to 4 carbon atoms, with the proviso that both of the R.sup.1 and R.sup.2 groups are not both hydrogen at the same time, or a physiologically compatible water-soluble salt thereof. The invention also includes new 2,5-diaminobenzonitrile compounds of formula I.
摘要:
Supplementary metallized connection parts short-circuiting or connecting incremental sub-components of one or more circuit elements of an integrated circuit are laid down on the semiconductor slice at the same time as the usual metallized connection pattern is made. The components associated with the incremental sub-components are measured to determine the program of adjustment and selective burnout of the supplementary connections. The selective burnout is carried out by applying a sequence of pulses to the segments to be burned out under monitoring by a measuring circuit, which blocks the delivery of further pulses, either immediately or after one or a few more pulses, when the measuring circuit detects the opening of the connection. The process is preferably carried out on integrated circuits before the semiconductor slice on which they are made is separated into individual circuit units. The pulses are applied in sequences in which individual pulses or series of pulses have increasing amplitude and/or pulse duration and/or pulse frequency.
