Definitions

  • the aim of the invention is to counteract this habituation effect. To this end, the invention is defined as described in claims 1 and 7.
  • Figure 1 shows the timing diagram of a preferred simple embodiment of the invention, in which only two different states of the signal generator are generated.
  • This can be, for example, the light and dark state of a yellow flashing light in road traffic, but equally well two different intensities of a light signal of any color, for example in rail traffic, the "ringing" and “silent” states of an alarm clock or two different tones of an alarm siren.
  • These states are simply labeled O and 1 in the diagram, although they do not have to refer to an on and an off state.
  • the states corresponding to the designations O and 1 can correspond to an intensive and a weak phase of a single signal lamp, but equally well to an alternating yellow and orange light or the lighting up of one of two same-colored, adjacent lights of the same color.
  • the abscissa t in the diagram represents time.
  • the duration of state 1 is limited downwards by the fixed value A each time it occurs. At this value comes a randomly selected time interval B 1, B 2, B 3 ... every time state 1 occurs. As a rule, the length of this time interval is set to an upper limit, designated B0 in FIG. 1a.
  • state O in FIG. A has an adjustable but fixed value R.
  • both states have an adjustable minimum duration A or R, to each of which a randomly selected duration B i or S i is added, which is limited by the adjustable values B0 or S0.
  • Figure 2 shows the timing diagram of a signal generator with four states: light green, dark green, light red, dark red. It always alternates a pair of light and dark states of one color with the same pair of states of the other color. For the sake of simplicity, it was assumed that all status pairs of the "green” variety have the same duration G and all those of the "red” variety have the same duration R, although this is of course not necessary. Within each pair, the duration of the first state H i or S i is chosen randomly between zero and the possible maximum value G or R. As a result - without changing the color of an optical signal - the viewer's attention is drawn more strongly to this signal, which in some cases can be limited to a single color, usually red.
  • the signal sequences described with reference to FIG. 1 or 2 can be generated, for example, by a circuit whose block diagram is shown schematically in FIG. 3.
  • a central data processing unit (CPU) 1 is powered by a power source (not shown).
  • the central unit has access to a memory unit 2, which contains both an active and a dead memory, and can be programmed by suitable selection of the data stored therein.
  • the signal sequences generated by the central unit 1 are fed to an interface 3, which generates suitable output signals for two driver circuits 4a, 4b, which in turn are set up to control a signal lamp 5 or a signal horn 6.
  • the central unit 1 is programmed to allow certain states of the lamp and / or the horn to last for a respectively pseudo-randomly determined time period.
  • FIG. 4 shows a simplified flow diagram of the program sequence for controlling a signal with the two alternating states ON and OFF.
  • the duration of the signal ON should each consist of a fixed time t BE plus a variable component t VE , while that of the signal AUS is composed of a fixed time t BA and a variable component t VA .
  • the flowchart in FIG. 4 shows an in principle endless loop for alternately generating the ON and OFF signals, each of which has a duration which is randomly determined between two limit values.
  • program branches (not shown in FIG. 4) are usually provided for the initialization and for the correct termination of the entire process as well as further auxiliary routines, but this is familiar to the person skilled in the art and need not be described further here.
