Abstract

Transmitter-receiver assembly with matched characteristics allowing the receiver element, with the desired colours and shape, buried in a synthetic resin, to reveal its recognition of the signal transmitted by the transmitter element, the latter displaying the recognition of its own signal by the receiver element.

Description

The present invention relates to a method for identifying and authenticating a product by including a circuit with specific characteristics in a synthetic material representing
the manufacturer's mark in shapes and colors.

 We have already tried in the past to guarantee the origin and authenticity of a product by registering a brand, a logo, a shape or an assembly of colors. However, counter-factors mimic the objects, their shape and / or their packaging and thus make unfair competition difficult to detect.

The present invention proposes the creation of labels or badges in the forms of the manufacturer which include a receptor element, visible or invisible, capable of identifying a signal with the characteristics known only to the manufacturer and of making known that this signal has been recognized as the agreed signal, the signal-emitting element being able between an emitter of ultrasound, magnetic fields, infrared signals
red, computer or electronic signals, etc.

 The receiving element is included in a piece of synthetic material placed, preferably on an adhesive synthetic material on which it will have been produced, in the technique in accordance with the rules. of art, one or more blocking oscillating circuits and decorated by a serigraphy or any other process reproducing the acronym, the name or any other inscription; instead of a blocking circuit, we could have laid a track or an electronic chip, the whole being covered by a synthetic material or a transparent resin or gold neck. The main characteristic of this receiving element is to receive and analyze the composition of the signal of the transmitting element and to make known whether it conforms or not to the characteristics for which it has been preset and to make it known by any suitable means.

We can imagine the interest represented by the use of these elements by any industrialist, trader, customer, as well as by any administration responsible for knowing the origin or destination of a product, the receiver element being in conformity with the brands and product creator's logos. It is understood that the characteristics of the signal can change at the request of the creator who may wish to identify a type of product or a year of manufacture in his product range and that the change of signal from the emitting element will have been preceded by change
characteristics of the receiver element.

n by way of example, without limitation, a preferred embodiment of a transmitter element and of a receiver element according to the present invention has been described below and it is illustrated schematically in the accompanying drawings.
Figure I is an overview of this embodiment
Figure II is a sectional view along the line RA 'of Figure I where we see in BR' the section of an electronic chip
Figure III is a plan view of Figure I along CC 'which shows in D the blocking circuit produced, in this case 5 in screen printing
Figure IV is a view of the front face of the transmitter which includes at E a colored diode, green for example. In F, another diode of another color, red, for example. The lighting of these dipods alternately can be for green the confirmation of the authenticity of the origin of the product and red as the advertisement dontre .

 + açon. We can see in G a transistor emitting a sound when the receiving circuit has identified a signal.

The box drawn in Figure IV estwici, a radio frequency transmitter, transmitting a frequency calculated to close the blocking circuit placed on the object to be authenticated according to the previous description. It could be ultra-sonic in nature or transmit computer signals. In this case, the receiver element would have been made to recognize this type of signal.
