Definitions
- ROM read only memory
- More advanced systems allow reading and writing, which makes it possible to modify the information stored according to the evolution of the product over time and thus ensure its traceability.
- the simplest systems use static memory
- RAM powered by a long-life battery, for example a lithium battery.
- EEPROM electrically programmed
- Information can be accessed, for example, by one or more contacts, as in smart cards.
- magnetic coupling implies the use of at least one coil. This way of doing things has different drawbacks. For example, such a label cannot be attached to a metallic object, which represents a magnetic short circuit which derives the energy intended for the label. Nor can several labels be placed close to each other because there is a risk of interference. Finally, the coil is a relatively large and delicate component.
- the present invention relates to an electronic tag without remote read or read / write contacts which does not have these drawbacks.
- This label which comprises at least one electronic memory capable of retaining its state in the absence of a power source and a circuit for controlling this memory is characterized in that it comprises at least one combination of cells of the electro- optics arranged so as to supply said memory and its control circuit when a light ray is sent on the surface of said cells, and at least means connected to said control circuit arranged so as to transmit outward light signals related to the content of said memory.
- FIG. 1 shows by way of example the basic diagram of a label according to the invention.
- FIG. 2 shows by way of example a more detailed diagram of the memory with its control circuit.
- FIG. 3 shows by way of example the construction of a label according to the invention.
- FIG. 4 shows by way of example a label according to the invention combined with a bar code.
- FIG. 5 shows by way of example a label according to the invention combined with an optical centering target.
- FIG. 1 there are 4 electro-optical cells 1, for example photo-voltaic cells on amorphous silicon or AsGa cells on crystalline silicon.
- the control circuit 2 will include a circuit making it possible to limit this supply voltage in the event of too violent lighting of the cells.
- the control circuit 2 is connected to the base of a transistor 5 which supplies, for example, 2 light-emitting diodes 6 via a resistor 7. It is thus possible, by means of these light-emitting diodes, to send outwards light signals related to the content of the memory.
- These signals can be detected by known means.
- the diodes are of the IR type, an IR detector such as those used for the detection of persons can be used. It is also possible to send light signals by varying the incident light, that is to say by variation of the part * ⁇ ray light which is reflected by the label.
- control circuit 2 switches on automatically when the supply voltage reaches a sufficient value, permanently scans the entire memory and sends the corresponding signals via the transistor 5 on the diodes 6. It would thus be possible to permanently read the content of the memory as long as the cells 1 are sufficiently lit.
- a more efficient solution consists in using an EEPROM type read / write memory which retains its information in the absence of a power source. It is then necessary to be able to send the information to be stored in the memory and to control the various read and write sequences from the outside.
- an optical detector for example a photo-diode 8 connected by an input 9 of the control circuit 2 to an amplification and shaping circuit of the latter.
- the internal configuration of the control circuit 2 is given in more detail in FIG. 2.
- Another simpler solution consists in directly using all or part of the electro-optical cells 1 to detect these modulations.
- these cells can have a sufficiently short reaction time to introduce control signals by short interruptions of the light ray (all or nothing modulation) at a frequency of the order of several kHz. These short interruptions are filtered by the diode 3 and the capacitor 4 so that their influence on the supply voltage is negligible.
- the control signals generated by the cells 1 are then applied to the input 9 of the memory control circuit 2.
- Another even more interesting possibility consists in using the light-emitting diodes 6 as photodetectors. We know that these elements can be reversible and can therefore be used as transmitters and receivers.
- This configuration makes it possible to completely separate the energy supply part represented by the cells 1, and the information transmitter-receiver part represented by the diodes 6. This separation can also be done at the wavelength of the light beams. .
- the energy supply part we will use for example a white light similar to sunlight.
- the transmitter-receiver part we will preferably work in infrared, which gives a much more selective light and therefore less sensitive to external disturbances.
- the diodes 6 are reversible and also used as photo-detectors, it is these which are connected to the input 9 of the control circuit 2.
- the 3 connection possibilities of the input 9 are shown in dotted in Figure 1.
- the energy supply will therefore be made permanently by concentrating on the label a ray of white light 10, and the communication of information by a bidirectional infrared ray 11.
- the prism 12 of the figure allows to combine these two rays so as to schematically represent the functioning of the system.
- FIG. 2 shows by way of example the internal configuration of this control circuit with the associated memory.
- the control signals 20 are applied to the input of a shaping circuit 21 which generates the different operating sequences of the label and delivers rectangular signals to the input of a serial / parallel converter 22.
- This converter is arranged so as to decode the information transmitted from the outside in serial form via the light ray so as to control the memory 23 with its address inputs 24, its data input-output 25, reading 26 and writing 27.
- this kind of EEPROM memory generally includes a voltage booster 28 which engages during writing and makes it possible to fix the new data to be recorded.
- Figure 3 shows by way of example the construction of a label according to the invention.
- the various electronic elements are removed on a support 31 fixed in a tubular housing 32.
- the capacitor 33 (4 of fig.l).
- the support 31 can be a double-sided printed circuit comprising the interconnections between the different components.
- the capacitor 33 of the SMD type, is soldered directly to the printed circuit.
- the integrated circuit 36 may include bumps and be fixed by thermocompression, while the electro-optical elements are connected by bonding 37.
- the light-emitting diodes To send information to the outside, it is typically necessary to supply the light-emitting diodes with at least imA so that they deliver easily detectable light signals, which represents 5 mW at 5 volts.
- the IR diodes can be modulated at high speed so that one can send a byte in a few microseconds, so that the average power can easily be reduced to 10% of the peak value, ie 0.5 mW.
- the integrated circuit comprising the memory with its control circuit and the diode typically has a surface of 4 mm 2 (techno Faselec SAC MOS 2 microns, capacity of 256/8 bits). Light emitting diodes for their part do not exceed 0.5mm / 0.5mm.
- the capacitor When writing, the capacitor must be able to deliver a current of 0.5 mA for 2.5 ms with an acceptable voltage drop. A value of the order of microFarad is therefore required. This is why a minimum size 1812 SMD capacitor must be provided.
- FIG. 4 shows by way of example a label according to the invention combined with a bar code.
- FIG. 5 shows by way of example a label according to the invention combined with an optical target.
