Device signalling the arrival of rescue teams

Abstract

 Electronic device signalling the arrival of rescue teams including:

• A transmitter installed on rescue vehicles which emits a coded signal during the time in which audio-visual devices have been activated;
• A receiver which, since it receives the coded signal transmitted by the transmitter installed on rescue vehicles, signals to the driver of the vehicle on which the receiver has been installed, by using an audio and/or visual device, the imminent arrival of a rescue team.

Description

Utility Model Field

[0001] The device can essentially be used in the street-safety sector and in the rescue teams rapidity while carrying out their duties.

[0002] It enables in fact, through a device including a transmitter and a receiver, to know when rescue teams will arrive much before being able to hear and/or see the classic emergency signals used nowadays by rescue teams.

[0003] If one knows in time that a rescue team vehicle is approaching to the vehicle we are driving, it is possible to decide in advance to stop our vehicle and/or pull alongside the kerb; in this way it is possible to act with a good safety level enabling rescue teams to drive on in a safer and faster way especially in city-traffic.

Front Engineering

[0004] The increasing spread of vehicles with air-conditioning facilities and the better soundproofing of the interior compartment of the last ten years have decisively influenced the habit of keeping drop-windows closed while driving.

[0005] Air pollution has certainly made the habit of keeping drop-windows closed much more common and necessary since its level is always very high in cities, especially in traffic-jams; the too high engine-noise and the noise made by vehicles passing by have also helped.

[0006] Excellent driving comfort can be obtained by keeping drop-windows closed and by music or whatever broadcast by radio stations since car stereos are almost always available on cars, they have the function of distracting and softening very much our perception of sounds coming from outside the car.

[0007] The result of silence and audio-comfort obtained by keeping our drop-windows closed, appreciated and researched by everyone, can potentially create the problem of not being able of hearing rescue vehicles with the normal distress signals switched on, unless these vehicles are at few meters from us; by doing so a rescue team is seriously slowed down whereas it should arrive quite quickly to the spot where the accident took place, to hospitals and/or where a very quick intervention is absolutely necessary.

[0008] Apart from the problem of slowing down rescue teams too much, because it is impossible to see and/or hear them from far away, accident risks with rescue teams or with other vehicles increase enormously.

[0009] The crossing of intersection always appears to be very dangerous especially if traffic lights should regulate them; it happens quite often that if one sees a green light, he/she is not very careful while crossing the intersection causing jamming of the brakes of our vehicles and of the vehicles behind us everytime one realizes that a rescue team is arriving in a few seconds.

[0010] By what explained above, it can be inferred that it is very important to know if a rescue team is arriving even if it is more than three hundred meters far from us.

[0011] To make concrete form to this idea, a device has been made resulting by two operative units strictly connected one to each other: a coded-signals two-way radio and a coded-signals receiver.

[0012] These two elements, which constitute the device, are installed: the two-way radio is installed on rescue vehicles; the receiver on vehicles.

[0013] The coded-signals two-way radio, installed on rescue vehicles, is switched on whenever an emergency intervention of the vehicle on which it has been installed is requested.

[0014] Once it has been switched on, the coded-signal is transmitted, preferably by the antenna of the rescue vehicle, to more than three hundred metres distance ( this distance is just an example and it is not restrictive in any way; this device in fact, can be used on any kind of distance without changing in any way the purpose for which it has been conceived ).

[0015] The receiving device switches on automatically whenever it is in the radius of action of the two-way radio and it gives information through audio and/or visual signalling abuot the arrival of the rescue teams.

[0016] In order to guarantee maximum safety, the two-way radio which has been installed on the rescue team vehicle, after having sent the distress signal, commutates into reception.

[0017] Whenever a signal which is similar to the one which has been sent is received, it tells the driver of the rescue vehicle by the same signals above; the driver can pay enough attention not to make dangerous conditions possible, through knowledge that another rescue team is operating in the same area.

[0018] As far as it has been said it can be inferred that the two-way radio which has been installed on rescue vehicles can have an intermittent working i.e. it takes a certain time to send the distress signal and recognize all the signals coming from other rescue teams.

[0019] After the time necessary for reception has passed, it commutates again into the transmission mode and it transmits a new distress signal; this process is repeated until it is switched off.

[0020] If the rescue vehicle hasn't got its own siren switched on, the device will work as a simple receiver with a similar behaviour to the one installed on private vehicles; it will only signal therefore the presence of other rescue teams in the same area.

[0021] The receiver installed on private vehicles also has another function: the signal reception can be temporarily switched off.

[0022] When the driver has been informed by the device that a rescue vehicle is approaching, the signalling is no more necessary and the reception of the signal can be switched off by simply pushing on a button. The device functionality will start again after a certain time has elasped.

[0023] It can be therefore inferred that when there is an emergency situation for the rescue vehicles (coded-signals transmitter on) the driver who is on his/her own car at more than three hundred meters distance from the rescue vehicle is told by the receiver installed on the car by audio and/or visual signalling about the presence of a rescue vehicle much before being able to hear and/or see the usual emergency signals which are present nowadays, sirens and flashing lights, on the rescue vehicle.
