Definitions

  • the present invention relates to a surveillance system of a person, in particular a system for enabling another person, for example a security manager, to understand whether a surveyed person has sustained an injury, also and especially when the two persons are distant from one another.
  • Distance surveillance of a person is an activity which can be usefully applied in a vast range of sectors of technology and civil society.
  • a surveillance of this type might be very useful for the care of elderly people, enabling them to receive swift help in a case where they have sustained a domestic injury.
  • a surveillance of this type might be equally useful in protecting the safety of workers sent to work in potentially dangerous locations, as can happen in the sectors of construction plant, logistics or telecommunications.
  • An aim of the present invention is therefore to provide a system which enables surveying a person in a way that is simple, rational and relatively inexpensive.
  • An embodiment of the invention therefore discloses a surveillance system for a person, comprising:
  • an accelerometer solidly associated to the shoe
  • an electronic processing unit configured for:
  • the system can note that the person wearing the shoe is in a potentially dangerous condition, for example whether he or she has been subject to an impact or invested by a heavy object.
  • the electronic processing unit can be configured to evaluate the variations of acceleration detected by the accelerometer.
  • the electronic processing unit can recognise whether the shoe has been subject to an impact.
  • the electronic processing unit can be further configured for:
  • the electronic processing unit can be further configured for:
  • the system is able to detect a "man down on the ground” position, i.e. the person wearing the shoe is likely to be lying on the ground unconscious.
  • the position of the shoe is to be considered in reference to the ground or in any case to the rest surface: the shoe can in fact be defined as being in a horizontal position when the sole thereof is resting on the ground on a horizontal surface, as in the typical case in which the person wearing it is in an erect position, while it can be defined as being in a vertical position or nearly vertical when the sole is perpendicular or nearly- perpendicular to the horizontal surface of the ground, as in a case in which the person is stretched out on the ground.
  • the shoe can be vertical or nearly-vertical both in a case where the heel of the shoe is resting on the ground with the toe part facing upwards, and in an opposite case where the toe part is rested on the ground and the heel facing upwards, and where the sole rests on the ground along a flank of the shoe.
  • vertical or nearly-vertical is taken to mean any inclination of the rest plane of the sole comprised between 0° and 20° with respect to the vertical, i.e. the direction of the force of gravity.
  • the electronic processing unit can be configured to evaluate the entity of acceleration detected by the accelerometer.
  • the electronic processing unit can establish if the shoe is stationary.
  • the electronic processing unit can be configured so as to determine the direction of the acceleration detected by the accelerometer with respect to a fixed system of coordinates connected to the shoe.
  • the electronic processing unit is therefore able to determine the inclination of the shoe.
  • the electronic processing unit can be further configured for: ,
  • the electronic processing unit can therefore be configured to acquire the acceleration detected by the accelerometer associated to the shoe and to identify the condition of free fall if, for a predetermined time lapse, the acceleration detected is close to zero.
  • the acceleration detected must be exactly zero (which is a condition that is practically impossible in reality), but it is sufficient for it to be less than a predetermined threshold value (for example close to zero), below which any residual accelerations detected are compatible only with a free fall.
  • the electronic processing unit can also be solidly associated to the shoe.
  • the shoe is in fact equipped with an integrated device able to carry out both the detecting function and the processing function of the acceleration signal.
  • the electronic processing unit can be configured so as to transmit the signal/s generated to a remote device.
  • the signals are transmitted and immediately recognised by the person in possession of the remote device, for example a security manager located even at a considerable distance, who can swiftly alert the aid services.
  • the electronic processing unit can be in direct communication with the remote device via wireless communication means. In this way an effective remote communication is guaranteed between the electronic processing unit and the remote device.
  • the wireless communication means can be radio means, for example Bluetooth Low Energy or low-frequency (e.g. 169 MHz). These radio systems have the advantage of requiring low-energy and easily- miniaturisable transmission and/or receiving infrastructures.
  • the electronic processing unit can be in communication with the remote device via a portable device, distinct and separate from the shoe, which comprises a further electronic processing unit configured for receiving the signal/s generated by the first electronic processing unit and retransmitting the signal/s to the remote device.
  • a portable device distinct and separate from the shoe, which comprises a further electronic processing unit configured for receiving the signal/s generated by the first electronic processing unit and retransmitting the signal/s to the remote device.
  • the portable device can comprise first wireless communication means with the device integrated in the shoe, such as for example Bluetooth, wi-fi, radio sub-GHz, NFC (Near Field Communication) and infrared, and second wireless communication means with the remote device, such as for example telephonic communication means, including GSM, GPRS, UMTS or others.
  • first wireless communication means with the device integrated in the shoe, such as for example Bluetooth, wi-fi, radio sub-GHz, NFC (Near Field Communication) and infrared
  • second wireless communication means with the remote device such as for example telephonic communication means, including GSM, GPRS, UMTS or others.
  • the signal sent to the remote device might be codified in a text message (for example an SMS text message or another) or in a vocal and/or acoustic message.
  • the signal/s generated by the electronic processing unit might be complex signals or more simply by alarm signals simply indicating the event or the condition detected.
  • a further embodiment of the invention discloses a functioning method of a control system for security of persons, wherein the system comprises:
  • the accelerometer generating a signal indicating the accelerations to which the shoe is subjected
  • the electronic processing unit receives the signal generated by the accelerometer, recognises if the signal received indicates that the shoe has been subject to an impact; and generates a signal indicating the result of this recognition.
  • This embodiment of the invention obtains the same effects described in the foregoing, in particular the effect of identifying and signalling a condition of danger for the person.
  • Figure 1 is a schematic representation of a surveillance system of a person according to an embodiment of the present invention.
  • Figure 2 is a schematic representation of a surveillance system of a person according to a different embodiment of the present invention.
  • reference numeral 100 denotes in its entirety a system for surveillance of a person, which comprises a shoe (105) wearable by the person to be surveyed.
  • the shoe 105 can be a shoe of any type, for example a sports shoe, a dress shoe, a gym shoe, a work shoe or a hard shoe, but might also be a boot, such as a mountain boot, a ski boot or in general any article of clothing able to be worn on the foot of the person under surveillance.
  • the shoe 105 will comprise a rest surface 1 10, which is normally defined by the sole and represents the surface which will go into contact with the terrain or floor when the person wearing the shoe 105 is stationary in an erect position.
  • the surveillance system 100 further comprises an accelerometer 1 5, which is solidly associated to the shoe 105 so as to be able to rigidly follow all displacements.
  • the accelerometer 1 15 is directly incorporated in the shoe 105 but, in other embodiments, it might be integrated in other objects which are solidly fixed to the shoe 105 itself.
  • the accelerometer 1 15 might be integrated in a ski or a snowboard engageable to the ski boot.
  • the accelerometer 1 15 can be a three-axis accelerometer, which is configured to detect the accelerations on three perpendicular axes X, Y and Z of a system of Cartesian coordinates solidly associated to the shoe 105.
  • the axes X and Y can lie in a parallel plane to the rest surface 1 10 of the shoe 105, while axis Z can be perpendicular to the preceding axes, i.e. vertical when the shoe is normally rested on the ground.
  • the accelerometer 1 15 is connected with an electronic processing unit 120, for example based on a microprocessor and possible equipped with a memory unit 125, which can be solidly associated to the shoe 105, so as to form, with the accelerometer 1 15, a single integrated device 130.
  • the accelerometer 1 15, the electronic processing unit 120 and the memory unit 125 have preferably small dimensions, so that the integrated device 130 can be housed and constrained in the shoe 105, for example in a special compartment fashioned in the shoe 105, for example the sole of the shoe 105, or integrated in an insert sole located internally of the shoe 105.
  • the surveillance system 100 further comprises a remote device 135 that is distinct, separate and independent of the shoe 105, which can be used by a second person acting as controller, for example a security manager.
  • the remote device 135 is in direct communication with the electronic processing unit 120 of the integrated device 130 via a wireless connection system.
  • the electronic processing unit 120 can be provided with wireless communication means, schematically denoted by reference numeral 140, which are able to place it in wireless communication with corresponding communication means, denoted in their entirety by 145, which are directly associated to the remote device 135.
  • This direct communication system can be a radio system, which uses a preexisting radio infrastructure, for example Bluetooth Beacon or Sub-GHz radio network.
  • Beacon Bluetooth systems create a radio proximity infrastructure (with a range of a few metres) while a Radio Sub-Ghz network, such as a Semtech Lo-Ra is a low-potential radio infrastructure (and therefore energetically compatible with a device incorporable in a shoe) which enables transmission of signals even at distances of kilometres.
  • These types of radio infrastructures also have the advantage of enabling, in some configurations, geographical localization of the radio emitter device 140, with no need to use an additional GPS system.
  • the person to be monitored wears the shoe 105, possibly after having activated the integrated device 130.
  • the electronic processing unit 120 constantly receives from the accelerometer 1 15 a signal (electrical) representing the accelerations to which the shoe 105 is subjected in the three Cartesian axes X, Y and Z, during all the activities of the person, including naturally the acceleration of gravity.
  • the electronic processing unit 120 can be configured such as to recognise whether the shoe 105 has been subjected to an impact, so as to generate a corresponding signal indicating this recognition (for example an alarm signal) and to transmit the signal generated to the remote device 135.
  • the person in possession of the remote device 135 is able to recognise whether the person wearing the shoe 105 is in a potentially dangerous condition, for example whether the person has been invested by a heavy object.
  • the electronic processing unit 120 can be configured to evaluate the variations of acceleration detected by the accelerometer 1 15 in a determined time lapse. If the variation in acceleration has at least a sharp peak of an entity greater than a predetermined threshold value, the electronic processing unit can recognise that the shoe has been subject to an impact.
  • the electronic processing unit 120 can also be configured to ascertain the direction of the impact from the signal received so as to generate a signal indicating the direction, and to transmit this signal too to the remote device 135.
  • the person in possession of the remote device 135 is advantageously able to know the direction of the impact or impacts to which the shoe 105 has been subjected, enabling reconstruction of the dynamics of the movement.
  • the electronic processing unit 120 can also be configured to recognise whether the signal received indicates that the shoe 105 is stationary in a vertical position or nearly-vertical position, so as to generate a corresponding signal indicating this recognition (for example an alarm signal) and to transmit the signal generated to the remote device 135.
  • a corresponding signal indicating this recognition for example an alarm signal
  • the fact that the shoe 105 is stationary in a vertical or nearly-vertical position can be taken as likely to mean that the person wearing it is lying on the ground unconscious.
  • the electronic processing unit 120 is therefore capable of distinguishing a "man down" condition, potentially dangerous, and inform the person in possession of the remote device 35 of this in good time, who can then swiftly alert the aid or assistance services.
  • vertical or nearly-vertical is taken herein to mean any inclination of the rest plane 1 10 of the shoe 105 comprised between 0° and 20° with respect to the vertical, i.e. the direction of the force of gravity.
  • the electronic processing unit 120 can be configured to evaluate the entity of the acceleration detected by the accelerometer 15.
  • the electronic processing unit 120 can establish if the shoe 105 is stationary.
  • the electronic processing unit 120 can be configured so as to determine the direction of the acceleration detected by the accelerometer 105 with respect to a fixed system of coordinates X, Y and Z solidly connected to the shoe 105.
  • the electronic processing unit 120 can also be configured to recognise whether the signal received indicates that the shoe 105 is in free fall, in order to generate a signal indicating this recognition (for example an alarm signal) and to transmit the signal generated to the remote device 135.
  • a signal indicating this recognition for example an alarm signal
  • the person in possession of the remote device 135 is placed in the condition of having greater information on the possible causes of the impact the person has been subject to.
  • the electronic processing unit can be configured to acquire the acceleration detected by the accelerometer
  • the acceleration detected must be exactly zero (which is a condition that is practically impossible in reality), but it is sufficient for it to be less than a predetermined threshold value
  • the electronic processing unit 120 is associated to the shoe 105, in other embodiments the electronic processing unit 120 might belong to the remote device 135. In this case the remote device 135 would receive from the wireless connection system only the "raw" signal generated by the accelerometer 1 15, which would be analysed by the remote device 135 itself.
  • Figure 2 illustrates a further variant of the surveillance system 100, which differs from the preceding one in that it further comprises a portable device 150.
