FR3113436A1 - Communicating and autonomous device to help the safety of isolated people. - Google Patents

Abstract

The present invention is a communicating and autonomous device for assisting the safety of isolated persons. It is innovative in that it is the only one in its field capable of sounding the alarm when no one is able to do so. Its autonomy lies in the fact that it is not made to alert in the event of an abnormal situation, but in the absence of a normal situation. This device has a camera which monitors without ever recording or transmitting the slightest image. . It does not contain any personal information, and fully respects the privacy of its users. The combination of the two sensors and their adjustment according to the installation data allow the reliability of the information. The communications being transmitted by a central device under permanent surveillance, since the proper functioning of the boxes is checked several times a day by this same central server, the risk of missing alerts linked to a failure of the hardware box or the user's means of connection to the Internet is practically non-existent. Autonomous, discreet and reliable, the present invention perfectly fills the gaps of existing devices in terms of the safety of isolated persons.

Description

Communicating and autonomous device to help the safety of isolated people.

Technical area
The present invention relates to the safety of the elderly, disabled, isolated, or simply living alone in their place of residence.

• Les caméras de surveillance. Elles présentent l’inconvénient de devoir être disposées en grand nombre de manière à couvrir l’ensemble du domicile de la personne surveillée. Elles présentent aussi l’inconvénient de devoir être consultées volontairement et régulièrement par quelqu’un. Elles présentent aussi l’inconvénient de réduire à néant l’intimité de la personne surveillée.
• Les dispositifs d’alerte par badge, bracelets ou colliers. Ils présentent l’inconvénient de devoir être portés par la personne vulnérable. Cette dernière doit donc le vouloir, le pouvoir et y penser. Ils présentent l’inconvénient de devoir être activés par la personne protégée, ce qui implique que cette dernière doit être consciente pour l’activer. Ils présentent aussi l’inconvénient d’être régulièrement activés involontairement, ce qui créé de la gêne, mais aussi de la lassitude, incitant les personnes alertées à moins de vigilance à l’égard de ces alertes.
• Les dispositifs de détection de chute. Ils présentent l’inconvénient de devoir être portés par la personne vulnérable. Cette dernière doit donc le vouloir, le pouvoir et y penser. Ils présentent aussi l’inconvénient d’être régulièrement activés involontairement, ce qui créé de la gêne, mais aussi de la lassitude, incitant les personnes alertées à moins de vigilance à l’égard de ces alertes. Ils présentent aussi l’inconvénient de ne rien détecter d’autre que les chutes.

State of the art
Different devices exist. All of them have different advantages and disadvantages but have one major disadvantage in common: they must be intentionally manipulated to be effective. Actions, punctual or recurring, and in any case frequent, must be carried out to activate or verify them, and forgetting them has the effect of rendering them ineffective.
Here are the existing devices:

• Surveillance cameras. They have the disadvantage of having to be arranged in large numbers so as to cover the entire home of the person being monitored. They also have the disadvantage of having to be consulted voluntarily and regularly by someone. They also have the disadvantage of destroying the privacy of the person being monitored.
• Warning devices by badge, bracelets or necklaces. They have the disadvantage of having to be worn by the vulnerable person. The latter must therefore want it, be able to and think about it. They have the disadvantage of having to be activated by the protected person, which implies that the latter must be conscious to activate them. They also have the disadvantage of being regularly activated involuntarily, which creates discomfort, but also weariness, encouraging alerted persons to be less vigilant with regard to these alerts.
• Fall detection devices. They have the disadvantage of having to be worn by the vulnerable person. The latter must therefore want it, be able to and think about it. They also have the disadvantage of being regularly activated involuntarily, which creates discomfort, but also weariness, encouraging alerted persons to be less vigilant with regard to these alerts. They also have the disadvantage of not detecting anything other than falls.

• La partie de la présente invention située au domicile de la personne protégée, appelée par la suite « Boitier Leyfe » est fixée dans un lieu de passage choisi du domicile, sur un support vertical parfaitement fixe, il est fortement recommandé qu’il soit placé à une hauteur supérieure à 80 centimètres du sol et ne faisant face ni à une fenêtre, ni une porte, ni un meuble, ni quoi que ce soit qui puisse être mobile, animé ou supporter un animal vivant. Un couloir est idéal et il est fortement recommandé que la distance du mur lui faisant face soit inférieure à 450 centimètres.
• Ce « Boitier Leyfe » contient une caméra qui scrute et détecte les mouvements dans son champ de vision. Le champ de vision latéral de la caméra est fixe et unique, tel que représenté dans la figure [Fig 7] annexée. Le champ de vision vertical est réglé selon les éléments de hauteur d’installation et de distance du mur faisant face dont il est question au paragraphe précédent. Cette division en 3 parties de la détection verticale permet de ne pas tenir compte d’éventuels animaux de compagnie ou personnes allongées au sol. Les zones de détections sont présentées par la figure [Fig 8] annexée.
  La zone de détection basse est désactivée dans tous les cas. La zone de détection haute est activée dans tous les cas. La zone de détection centrale est activée si le « Boitier Leyfe » est installé, soit à une hauteur supérieure à 120 centimètres, soit à une hauteur comprise entre 80 et 120 centimètres et une distance du mur lui faisant face inférieure à 300 centimètres.
  Les figures [Fig 9], [Fig 10], [Fig 11], [Fig 12] annexées détaillent les 4 possibilités.
• Un capteur de présence à infra-rouge scrute et détecte des mouvements dans son champ d’action, orienté identiquement à la caméra.
• La combinaison des détections simultanées par ces deux périphériques indique que le mouvement repéré est bien celui d’un être humain vivant en position verticale ou semi-verticale au sein du lieu d’installation et à proximité de l’invention.
• La scrutation de périodes précises (dites « phases ») déterminées en fonction des habitudes de vie de la personne protégée permet à l’invention de confirmer la bonne présence et activité au sein du domicile.
• La consignation de cette détection permet au système d’affirmer une présence de vie au sein du domicile à au moins un instant de la phase.
• En cas de phase réalisée sans aucune détection validée par la caméra et le détecteur infra-rouge simultanément, la présente invention alertera la personne de confiance désignée. (par exemple par email, ou par SMS, ou autre) sans aucune intervention humaine d’aucune sorte.

Description of the invention:
The present invention aims to remedy these drawbacks and mainly the drawback common to all these devices, namely the obligation of voluntary, daily and essential actions to make them effective. For this, the present invention combines detection, monitoring and alert in the following way:

• The part of the present invention located in the home of the protected person, subsequently called "Leyfe box" is fixed in a chosen place of passage of the home, on a perfectly fixed vertical support, it is strongly recommended that it be placed at a height greater than 80 centimeters from the ground and facing neither a window, nor a door, nor a piece of furniture, nor anything that may be mobile, animated or support a living animal. A corridor is ideal and it is strongly recommended that the distance from the wall facing it be less than 450 centimeters.
• This “Leyfe Box” contains a camera that scans and detects movements in its field of vision. The lateral field of vision of the camera is fixed and unique, as represented in the figure [Fig 7] appended. The vertical field of view is adjusted according to the elements of installation height and distance from the facing wall discussed in the previous paragraph. This division into 3 parts of the vertical detection makes it possible to ignore any pets or people lying on the ground. The detection zones are shown in the appended figure [Fig 8].
  The low detection zone is deactivated in all cases. The high detection zone is activated in all cases. The central detection zone is activated if the "Leyfe Box" is installed either at a height greater than 120 centimeters, or at a height between 80 and 120 centimeters and a distance from the wall facing it less than 300 centimeters.
  The appended figures [Fig 9], [Fig 10], [Fig 11], [Fig 12] detail the 4 possibilities.
• An infrared presence sensor scans and detects movements in its field of action, oriented identically to the camera.
• The combination of simultaneous detections by these two peripherals indicates that the movement detected is indeed that of a human being living in a vertical or semi-vertical position within the place of installation and close to the invention.
• Scanning specific periods (called “phases”) determined according to the lifestyle of the protected person allows the invention to confirm the correct presence and activity within the home.
• The recording of this detection allows the system to affirm the presence of life within the home at least one instant of the phase.
• In the event of a phase carried out without any detection validated by the camera and the infrared detector simultaneously, the present invention will alert the designated trusted person. (for example by email, or by SMS, or otherwise) without any human intervention of any kind.

  7. A micro-USB to RJ45 adapter allowing the first connection to the internet and the first configuration of the "Leyfe Box".
  8. An RJ45 cable allowing the first connection to the internet and the first configuration of the "Leyfe box".
• The central server called "MiddleMan" is a computer equipped with an operating system and selected software enabling it to liaise between the user interface on the website and the users'"LeyfeBoxes", to check the proper functioning of the "Leyfe Boxes" and to operate control programs for the "Leyfe Boxes" aimed at:
  1. Check the programming made by users on the user interface of the website and send them to the "Leyfe boxes".
  2. Confirm to users that their settings have been taken into account by the "Leyfe boxes". These confirmations are made for example by email, SMS or other.
  3. Check if the "Leyfe Boxes" have transmitted alerts during the phases that have been programmed. These alerts are made for example by email, SMS or other.
  4. Check the good network activity of the active "Leyfe Boxes" to ensure that they are able to transmit an alert at the desired time. These checks will take place at the beginning and end of the time slots configured by the users and the inherent alerts are made, for example, by email, SMS or other.
  5. Check, following a loss of network activity of the "Leyfe Boxes", a possible return to normal and alert users. These alerts are made for example by email, SMS or other.
  6. Check, for the purposes of the detection ranges configured by the user on the user interface of the website, whether the "Leyfe Boxes" report an alert and notify the user concerned, if necessary. These alerts are made for example by email, SMS or other. Once the first alert has been given, two additional alerts are, if necessary, scheduled 4 and 6 hours after the first. This operating mode is called “Danger”.
  7. Scrutinize the return to normal when the "Danger" mode is active on the "Leyfe boxes". When the return to normal is signaled by the "Leyfe Boxes", notify the designated users. These alerts are made for example by email, SMS or other.
  8. Check if users have paused their "Leyfe Box" by setting it from the user interface of the website, either by manually deactivating it, or by programming an interruption period called "Holiday Mode", with programmed deactivation and activation in advance. In the case of "Holiday mode", users are alerted on the days of deactivation and activation. These alerts are made for example by email, SMS or other.
  9. Check the validity date of the "Leyfe Boxes" subscription and deactivate them when their validity date has passed. Affected users will be notified before this date is exceeded so that they can renew their subscription. These alerts are made for example by email, SMS or other.
  10. Check the number of SMS remaining in the "Leyfe Boxes" package and notify the users concerned when their package is nearing its end. These alerts are made for example by email, SMS or other.
• The configuration interface allows users to view and program the coordination of all their "Leyfe" devices in order to obtain the detections and alerts as they wish. It allows you to view and adjust for each “Leyfe box”:
  1. The nickname that the user wishes to give to his "Leyfe Box" for more user-friendly and intuitive communications.
  2. The country in which the "Leyfe Box" is installed. This data is useful for the correct configuration of the Wifi connection of the "Leyfe Box".

  9. The dates of deactivation and activation of the "Leyfe Box" in the case of programming a "Holiday Mode". If a "Holiday Mode" is programmed, the "Leyfe Box" will be deactivated from the first phase of the selected deactivation day and activated again during the first phase of the selected activation day.
  10. A delete button to remove the "Leyfe Box" from the user's account.
  11. The number of text messages remaining available for alerts from his "Leyfe box". The user can add SMS in the form of a code corresponding to a package. This code will be entered by the user in the filling field provided for this purpose.
  12. The end date of the “Leyfe Box” subscription to alerts. This subscription can be extended in the form of a code corresponding to a duration. This code will be entered by the user in the filling field provided for this purpose.

Example :
Mr. Jean Dupond lives alone in his house located away from any other dwelling. Jean is 170cm tall and usually gets up in the morning around 8:00:00 a.m. and goes to bed at night around 10:00:00 p.m. Jean is equipped with an alert bracelet allowing him to warn his son in the event of a problem by pressing the button located on the dial of the bracelet.
His son Yann lives 10 kilometers from his father and brings a box of the “Leyfe” device which he will install in the hallway leading to his father Jean's bedroom. The “Leyfe Box” will be installed at a height of 120cm from the ground and the corridor will be 200cm wide, the wall opposite will therefore be 200cm away from the “Leyfe Box”
Yann goes to his configuration interface and adds the "Leyfe box" using the username and password provided. Once this has been saved, he can then configure it by entering the installation height from the ground, the distance from the wall opposite, the country of installation, the wifi parameters, his own contact details for the alerts, and time slots.
To match his father's lifestyle, Yann will set detection time slot No. 1 from 7:30:00 a.m. to 8:30:00 a.m. and detection time slot No. 2 from 9:30:00 p.m. to 10:00 p.m. :30:00.
Once this first setting has been made, he can go and install it on the wall using the self-adhesive pads provided.
Some time later, Jean gets up at 8:05:00 a.m. and goes straight to the shower room adjoining his bedroom. Leaving the shower cubicle, at 08:20:00, he slips, falls and hits his head on the edge of the shower cubicle. Jean fainted almost instantly, long before he could think of pressing the button on his alert bracelet which, in any case, had been on the edge of the sink in his shower room since the night before.
At 08:30:00, the “Leyfe” device analyzes the time slot that has just ended. No presence detection confirmed by the two sensors was recorded by the “Leyfe box”. The “Leyfe Box” then reactivates its communication systems. It is 08:30:12. Then it signals its correct operation and signals the “Danger” type alert, it is 08:30:17.
A few seconds earlier, at 08:30:00, the “MiddleMan” started its poll of all active “Leyfe” and ended a phase at 08:30:00. He checks the proper functioning report markers then, when one of them is confirmed by the "Leyfe box" concerned, checks the "Danger" alert marker It is 08:30:21 when the "MiddleMan" note the “Danger” marker on Jean’s “Leyfe Box”.
The "MiddleMan" immediately sends the alerts to the email and SMS coordinates that have been programmed on the user interface of the website.
It is 8:30:23 a.m., Yann is about to leave for work but he receives an alert from his “Leyfe” device via an SMS informing him of a “Danger” type alert.
It is 8:31:06 a.m., Yann takes his car towards his father Jean's, while calling the emergency services with his hands-free kit to tell them that he thinks an accident has taken place at Jean's home. his father.
It is 08:38:27, Yann arrives at his father's house and the firefighters are already there. Yann opens them, Jean is taken care of immediately and will be treated.
In this example, John was the victim of a domestic accident, rendering him inert and alone in his home. The “Leyfe” device alerted Yann and his father Jean was taken care of by the emergency services less than 20 minutes after the accident.
This example is a scenario and is not taken from real events. The figures and deadlines announced for the elements of the "Leyfe" device have been tested and verified in practice. Those concerning human actions and interactions are simple and plausible.

The present invention is in no way limited to the embodiments described and represented. It is intended to help protect isolated people. Its description, written above, was done so by indicating the current state of development of this device and its possibilities. This state is naturally evolutionary, the objective being mass production in an industrial way for distribution to the general public.
