Abstract: The rear mirror has a foot for fitting to the vehicle, and a mirror glass. The microphone is built into it, pref. at its outer free end so as to prevent as far as possible the pick-up of disturbing sound reflexes from the vehicle bodywork. Sound is picked up by the microphone only from a limited area in a well defined direction, the area being where another vehicle on approaching from the rear is in an oblique position in relation to the microphone. Such sound is of a frequency significant and common to vehicles circulating in every day traffic. The mirror incorporates a lamp fitted behind a red, transparent plastic plate bearing the text WARNING, located on the side of the mirror facing the rear of the vehicle, i.e. between the mirror glass and the vehicle and a near as possible to the driver to facilitate observation. A battery with associated current circuit connects the microphone to the lamp, so that the circuit incorporating the lamp is connected when the microphone is activated by sound from a vehicle approaching from the rear, causing the lamp to illuminate.

With the aid of instructions, a main memory common to both sequences is activated for data information reading/writing. Increased data handling capacity is achieved in the following manner: both sequences are executed in parallel to start with. During execution of the first sequence, the main memory is prevented from being activated for writing due to the second sequence write instructions. A write address and data information included in a write instruction associated with the second sequence are intermediately stored. The intermediately stored write address is compared with the read addresses of the second sequence, and data information is prevented from being read from the main memory in response to an identity of the addresses, the intermediately stored data information being read instead. An address included in a read instruction associated with the second sequence is intermediately stored if this address has not been previously selected in conjuction with a write instruction associated with the second sequence. The intermediately stored read address is compared with the write address of the first sequence and execution of the second sequence is restarted in response to an identity of the addresses.
