Definitions

  • This invention relates to a security system for testing for exposure of the contents of a container to a predetermined physical stimulus.
  • a problem associated with storing or transporting goods in a container is that of determining whether or not the container has been opened or if the goods have been exposed to adverse conditions which might cause their damage or deterioration.
  • perishable goods or goods which are easily damaged, for example organ transplants or sensitive electronic equipment
  • a security system for testing for exposure of the contents of a container to a predetermined physical stimulus, the security system comprising sensor means sensitive to the predetermined physical stimulus, the sensor means being located within the container and having an output state which can be determined from outside the container.
  • a system according to the invention allows the contents of the container to be tested for exposure to the predetermined physical stimulus without the container having to be opened.
  • the security system comprises transmission means for transmitting data representative of the output state of the sensor means in response to an interrogation signal.
  • the output state of the sensor means may be a continuously updated value of the physical stimulus sensed by the sensor means.
  • the value of the physical stimulus can be determined at the moment of reading.
  • the output state of the sensor means is indicative of whether said predetermined physical stimulus has crossed or has not crossed a predetermined threshold value, and in this case the transmitted data would not be updated even if the threshold was crossed again.
  • the transmitted data would provide an indication that the physical stimulus has crossed the predetermined threshold value, indicating that the container has been opened or that the contents of the container have been exposed to potentially damaging conditions.
  • the transmission means may be resettable to permit it to be used again after the threshold had been crossed, or the transmission means may be a one-use device that cannot be reset.
  • the transmission means is, ⁇ referably, a passive device which is powered by energy received from an interrogating transceiver, and may be in the form of a transponder, such as an r.f. transponder.
  • the transmission means may include data storage means for storing identification data.
  • the transmission means may comprise a first data storage means storing first identification data, and a second data storage means storing second identification data; and said sensor means causes the transmission means to transmit either the first or the second identification data in dependence on the output state of the sensor.
  • the transmission means may have more than two said data storage means, each storing respective identification data, and said sensor means causes the transmission of identification data from a respective said data storage means in dependence on the output state of the sensor.
  • the physical stimulus to be sensed may be pressure, temperature, light, magnetic flux, humidity or any other parameter.
  • the container in which they are placed may be a sealed container having a pressure differential between its interior and exterior, and the physical stimulus sensed by the sensor means would then be pressure. If the container's seal is broken, the resulting pressure change will be sensed by the sensor means.
  • FIG. 1 is a schematic representation of a security system in accordance with the invention.
  • Figure 2 is a block circuit diagram showing one embodiment of a sensor and tag forming part of the security system of Figure 1, and
  • Figure 3 is a block circuit diagram showing another embodiment of a sensor and tags forming a part of the security system of Figure 1.
  • the security system includes a sensor 1 sensitive to a predetermined physical stimulus, e.g. pressure, temperature, humidity etc, and a tag 2 in the form of an r.f. transponder.
  • the sensor 1 and tag 2 form a unit which is placed within a container 2 together with goods 4 being transported or stored.
  • the r.f. transponder which may be of known kind (e.g. the TIRIS tag manufactured by Texas Instruments) is a passive device which transmits data in response to a r.f. interrogation signal from a transceiver 5.
  • Figure 2 shows one embodiment of the r.f. transponder and its associated sensor 1.
  • the r.f. transponder comprises an antenna 21 which is tuned to the frequency of the r.f. interrogation signal by means of a tuning capacitor 22.
  • the r.f. interrogation signal is transmitted by transceiver 5 as a pulse of r.f. energy which is received by antenna 21, rectified by a diode 23 and stored temporarily in a storage capacitor 24.
  • a power circuit 25 detects when the interrogation pulse has ended and, in response to such detection, causes capacitor 24 to discharge, whereby the stored energy is retransmitted as a r.f. signal via the tuned antenna 21.
  • a control circuit 26 modulates the frequency of the retransmitted signal in accordance with both the current output state of sensor 1 and a unique identification code which is permanently stored in a memory 27.
  • the resultant frequency- modulated signal is received by transceiver 5 where it is de-modulated in order to recover the output state of sensor 1 and the identification code of the tag 2.
  • the senor 1 and tag 2 are placed inside container 3 together with the goods 4.
  • the tag may then be initiated, in known manner, by means of a signal transmitted by a tag-programmer 6, and subsequently interrogated, in the afore-described manner, to determine the output state of the sensor and the identification code of the tag.
  • the container 3 may conveniently be a vacuum-sealed plastics material bag.
  • sensor 1 would be a pressure sensor having an output state which changes if the pressure in the bag increases due to the vacuum-seal being broken.
  • the identification code stored in memory 27 of the tag may represent the number 14328, whereas the transmitted data may represent either the number 114328 or 014328 depending on the output state of the sensor 1 - if the leading numeral is "1" this represents the existence of a vacuum indicating that the seal has not been broken, whereas a "0" represents a higher pressure indicating that the seal has been broken.
  • the tag 2 and sensor 1 may have a non-retriggerable action after initial activation by the tag-programmer 6. That is to say, if the seal is broken and the vacuum destroyed the leading numeral will remain at "0" even if the vacuum is subsequently restored during resealing.
  • the tag 2 and sensor 1 would then be a one-use device. However, where it is desired that the tag 2 and sensor 1 may be re-used, the tag can be reset one or more times by the tag-programmer 6.
  • the container 3 may be pressurized to cushion the equipment.
  • the pressure sensor 1 may then be used, as before, to sense if the seal is broken, in this case, the tag being responsive to a decrease of pressure, below a preset pressure threshold.
  • the data transmitted by tag 2 will be modified.
  • the data may, for example, be 014328 when the seal has been broken, 114328 when the pressure is normal or 214328 when the pressure is high indicating a severe bump during handling. This data may revert to its original state or may be changed permanently depending on the application. Where it is desired to detect when the equipment has experienced excessive shock at some stage during its journey or storage the change will be permanent.
  • a similar arrangement could be used for sensing and/or recording the crossing of a maximum or minimum temperature threshold using a temperature sensor instead of a pressure sensor. Such an arrangement could be used in the case of storing and/or transporting transplant organs.
  • FIG. 3 of the drawings illustrates a yet further embodiment of the invention in which tag 2 comprises two transponders 20,20' sharing a common antenna 21.
  • sensor 1 operates as a switch which connects antenna 21 to one or another of the transponders in dependence on the output state of the sensor.
  • the two transponders have respective memories 27,27* storing different identification codes. Accordingly, the retransmitted r.f. frequency will be modulated in accordance with one or the other of the identification codes thereby indicating the current output state of the sensor.
  • the tag may include a corresponding number of transponders.
  • each transponder could have its own antenna, the sensor 1 being used to switch between the antennas according to the sensor's output state.
  • a number of containers 3, each with a tag 2 and a sensor 1 are present in close proximity there may be a risk of interference due to all the tags responding to the transceiver 5 simultaneously. The possibility of this occuring can be reduced by using tags programmed not to respond to interrogation unless, for example, the predetermined physical stimulus had exceeded a certain threshold. If the sensor 1 is a pressure sensor this might occur if the pressure had changed during transit or storage because, for example, the container 3 has been opened, or has been subjected to excessive pressure.
  • the senor 1 may incorporate a capacitor which is short circuited and discharged when the sensor 1 is triggered by the crossing of a threshold of the physical stimulus which is being sensed. Once discharged the state of the sensor 1 will remain unchanged. A special signal would then be required to recharge the capacitor.
  • transceiver 5 and the tag-programmer 6 may be of known kind, and in the described embodiments they are shown as separate units. For some applications such as where the contents are held in storage, it will be convenient to combine the transceiver 5 and the tag-programmer 6 into one unit.
  • the concept of placing valuable items in a vacuum sealed container is especially advantageous in the case of banknotes being transported in a security box. In the event of a security alert the bank notes can be destroyed by exposing them to microwaves generated by a microwave source installed in the box. The notes will be destroyed without them catching fire because the container is evacuated.
  • the invention is applicable to security systems for monitoring the contents of packages or containers while they are being stored or transported.
