Abstract
A system for detecting labels arranged on a support and spaced apart from one another by a spacing, the system including a transmitter part including a transmitter arranged to transmit a beam of ultrasonic waves towards the support which carries the labels, a receiver part, separated from the transmitter part, such that the support carrying the labels can pass along a plane located between the transmitter part and the receiver part, the transmitter part or the receiver part being arranged so that the beam of ultrasonic waves transmitted by the transmitter covers, on the support carrying the labels, a total surface area in which the surface area occupied by the spacing between two labels is greater than the surface area occupied by the labels.

A system for detecting labels arranged on a support and spaced apart from one another by a spacing, said system comprising:
- a transmitter part comprising a transmitter arranged to transmit a beam of ultrasonic waves towards the support which carries said labels,
- a receiver part, separated from the transmitter part, such that the support carrying the labels can pass along a plane located between the transmitter part and the receiver part, in a passage direction, and in a passage plane, the receiver part comprising a receiver arranged to generate an output signal on the basis of a beam of ultrasonic waves attenuated by the support and/or the labels,
- wherein the transmitter part or the receiver part is arranged so that the beam of ultrasonic waves transmitted by the transmitter covers, on the support carrying the labels, a total surface area in which the surface area occupied by the spacing between two successive labels is greater than the surface area occupied by the labels.
