Prior art

There are several devices on the market security but that, for the most part, are autonomous systems that incorporate a GPS to know the position of the individual, as well as a GSM or GPRS communication system, thus incorporating a mobile phone. The problem with these systems is the size, necessary to house such equipment, the short duration of the battery and response speed, necessarily long due to the time required to activate the GSM-GPRS device and register it on the network and activate the GPS and get position. Yes the device is always registered in the network and with GPS position in anticipation of a possible alert, the battery requirements are much older. Another problem, if it is equipped with GPS, is that it must be in a place not too hidden to allow the antenna GPS receiver get position.

There are also teams that send a signal from alarm to equipment specially designed to communicate with they. These are normally used in the homes of users If you intend to use these systems in an area extensive geographical it would be necessary to install millions of these repeater equipment, with a cost that makes this feasible possibility, in addition to the inherent compatibility issues between systems

It is therefore desirable, a system that uses the mobile phone network, rather, mobile phones themselves of users or WIFI®, which normally covers most of the inhabited areas of any geographical area. Your design is very simple and only requires to incorporate a software in the devices referred to herein as "bridge."

Spanish patent ES 2222086 describes a location system for personal security, characterized because it mainly uses GPS and Bluetooth® technology, composed of a personal locator with alarm, and a center for control, which manages the information received from the locators personal, being able to track in real time, and / or deferred, and a remote control of alarms.

US7502619 describes a system for the location of a wireless device over a wide area that includes transmitting devices, but not receivers, configured to emit a series of signals that are likely to be received by a central reception which is what determines the location. However, the phone's GPS slows down a lot location and complicates it. In addition, you cannot distinguish between the person or object carrying the device to decide if the alarm It is presented on the phone or sent to the control center.

US20020175819 describes a method of rescue using Bluetooth®. The plurality of devices involved generate a packet of emergency messages that are transmitted to other devices attached to a network. The Bluetooth® device which receives the emergency signal, will automatically execute a default program in the event of such emergency.

Explanation of the invention.

The object of the present invention is a device and system that allows to transmit alerts in a way efficient, with reduced energy consumption, using it WIFI networks or mobile communication networks and mobile phones connected to her. The connection between the security device and the mobile phone or WIFI access point ("bridge" element) is carried out through a wireless link, preferably Bluetooth® or WIFI, and from the mobile phone or access point to the control center, through the free connection to 112 or via a GPRS or IP connection. The position of the device security that creates the alert can be ascertained by triangulation of the bridge device that sends the alert if it is also a telephone mobile (it is also possible to use your GPS if you have it incorporated), by the known geographical position if the bridge device is a point WIFI access or through the security device, if optionally incorporates a GPS. In addition, the security device can incorporate other sensors that are capable of generating the automatically alert, in addition to the button. For example, a meter of pulsations, blood pressure, temperature, etc. Function The type of alert or the individual carrying the device is possible to choose the way in which the alert is processed. In some cases it may be convenient to show the alert in the surrounding mobile phones, for example when it is a problem of health of the person wearing the safety device (in these cases the device called "bridge" is not used as such since it is the recipient of the alert), while in others, what convenient is to use the surrounding mobile phones to Send the alert in a hidden way.

To solve the technical problem derived from sending an alarm from a single device with very low consumption (since in its basic configuration it remains "asleep" until that is used) and size the security device is presented low-power and small-sized notebook, object of the present invention patent, which comprises at least:

(a) first means of capturing alarm situations In its basic version, a switch configured for the device to send the alarm when activated (for example in a dangerous situation), or for not being activated after a certain time (if taken by a baby or a person with any disease that prevents you from doing so). Optionally, any device that identifies any possible alarm situation, a heart rate monitor, blood pressure monitor, thermometer, etc.

(b) a few second means signal processors configured to process the data collected by the first, of such that this data treated, together with a unique identifier of each device, can be sent by some

(c) third party media, a bluetooth device or Wifi communication to connect to an external receiver element, what has been called the "bridge" device, a point of Wifi access, a mobile phone with Bluetooth or Wifi. Necessary also modify the software that currently contain the devices that have been called as a bridge to accept connections of this type of safety devices without needing user intervention and to send the alert to the center of control and / or display it on the screen and / or emit some kind of sound of alert automatically.

Throughout the description and the claims the word "comprises" and its variants not they intend to exclude other technical characteristics, additives, components or steps. For those skilled in the art, other objects, advantages and features of the invention will be partly detached of the description and in part of the practice of the invention. The following examples and drawings are provided by way of illustration, and are not intended to be limiting of the present invention. In addition, the present invention covers all possible combinations of particular and preferred embodiments indicated herein.

Preferred Embodiment of the Invention

As can be seen in Figure 1, the portable safety device with low power consumption and small size understands

some means 1 of possible situations emergency where these means include, in turn, one of the following:

a push button, activated when pressed or not in a while determined,

or a device Biometric of any kind, such as a heart rate monitor, a blood pressure monitor, thermometer, etc;

signal processing means 2, where the information obtained by the capture media is processed and where, through transmission systems by radio frequency 3 (preferably of the type Bluetooth ® or WIFI), communicate with the "bridge" device 4, usually a mobile phone or a WIFI access point wireless, configured as a signal transmitter medium.

Thanks to the use of the "bridge" device 4, and from it the alert is sent to the control center 5, sending the relevant data that include at least the type of alarm, and the identifier of the device that generated it.

In figure 2, the different ones are shown steps for the operation of the mentioned device, and that They comprise at least:

(i) a first stage (fig. 2a) where security device 10 is in a normal environment surrounded by mobile phones 11 connected in turn to antennas of mobile telephony 12;

(ii) a second stage (fig. 2b) where the Device alert is activated, either by pressing or not a button or by the measurement obtained from any of its sensors biometric;

(iii) a third stage (fig. 2c) where the device 10 emits the alert signal to the devices "bridge" 4 that has in its radius of action. On the last versions of the Bluetooth® 100 meter specification, as in the case of WIFI access points. At this time of the sequence, the alert is already being sent through the "bridge" devices 4, in this case mobile phones. The alarm center already knows that the alert and position has been activated approximate of the device that generated it. This calculation is performed thanks to the geographical position of the antennas is known. It is calculated by obtaining the antennas that are within reach of the bridge device and the signal strength that is obtained from each one of them. Once the "bridge" device is located, it is possible to know the radius in which the device is located security and position with more precision if you have at your fingertips Several bridge devices, again by triangulation. The position it is quite accurate since the information of several "bridge" devices 4 simultaneously which in turn have information on the antennas that are within your reach. At the same time, Normally, there are several "bridge" devices within reach of a safety device with what the position estimate is even older This is easy to verify, when in our mobile phone we activate the option "search for devices bluetooth "or from our computer" connect to the point of Wi-Fi access "the most common is to have several available. Sometimes even tens.

(iv) a fourth stage where despite the fact that the device 10 move, or do so-called "bridge" 4, the device 10 always uses the closest ones. It connects to new "bridge" devices 4 which in turn are connected to new 12 antennas that give the new position.

Figure 3 shows a diagram of operation, where when one of the capturing means of Alarm situations are activated (100), the computer starts the search of Bluetooth devices within reach (101). As soon as he finds One (102) tries to connect. The search only stops (103) when the alarm ends if caused by a sensor or when time passes default or because it is simply canceled. You have to have in account that mobile phones can be configured so that are not visible by other Bluetooth devices and also in depending on the security level configured, may require User authorization before accepting a connection. Obviously, since this is an alarm device, it is necessary configure the "bridge" devices to accept these connections regardless of the bluetooth settings that the "bridge" device have. This is possible to do several shapes. One of the simplest is to book certain MAC addresses for devices of this type. IEEE standard 802 allows more than 281,474,976,710,656 possible network addresses, therefore, it is very easy to book, for example, all those that start with aa- (in hexadecimal notation there are six groups of two numbers, in the example the first two are used) for this purpose. From this way, any "bridge" device that receives an attempt of connection of one of those MAC addresses would accept that connection (104). Once the connection (105) is established, two can be given different situations:

to)

If the "bridge" device is the recipient of the alarm (106) it would display the message (together with a beep and / visual signal) that comes from the safety device. This message could include information related to the type of alarm generated, the device code, the name of the user, telephone (to notify family members if they are an elderly person, or a small child), etc. The user would know at that moment that a person has the need to be treated within a radius of 10/100 meters (depending on the scope of the device). If the "bridge" device is a WiFi access point, you can send the same message but with a message broadcast chain type (broadcast) to all networked computers.

b)

If he recipient of the alarm is the control center (107), the Alert notification could be done through 112, sending an SMS to a toll-free number, 112 style in voice calls or through a GPRS connection to a toll-free number and that only allow connections to the server that collects requests from emergency, to avoid fraudulent use of it. The content of the message is similar to case a) and is also expandable, type of alarm generated (push of a button, biometric sensor, etc.), the device code, user name, phone, GPS position if is known and / or antenna / antennas that are within reach, to obtain the approximate position of the safety device.

The security device would only stop the search for "bridge" devices if the alarm ends, passed a certain time or because it is canceled.
