WIRELESS EXPANSION UNIT FOR A PORTABLE COMMUNICATION DEVICE

The invention relates to a wireless signaling device according to the preamble of claim 1.

Recently the number of different mobile communication devices increased in an explosion-like manner, which in addition to the traditional task of speech communication provide other contact establishing and contact keeping possibilities for the users. The majority of this type of communication devices are represented by so-called "smartphones", a feature of which is that they are able to keep and run different installed programs. The communication devices are usually such end user devices, which are in indirect or direct connection with the appropriate technical device of a service provider - this may be a base station - and thanks to this the communication is always done with the aid of the infrastructure that is provided by the service provider, that is, through this infrastructure.

One of the groups of applications that may be run on portable communication devices is represented by the applications, which - in general - serve remote supervision, alarming and help requesting purposes. It is a common feature of these applications that due to the nature of their function they consist of two main parts. One part of theirs is installed on the mobile communication device, while their other part is installed on the device that takes care of the receiver tasks as a general rule. This second device may be another mobile device, however, in the case of widely used solutions it is a dedicated network device of the service provider, more exactly a software that is run on a network device of this type. Usually these application operate as follows. They are either activated on the mobile communication device when their operation is desirable, or they may be applications that are always running on the device in the background. After being activated they send some message of a defined type, format and content to the other receiving part or device, and this latter one executes a reaction that depends on the existing application, which may be a completely automated machine response, but it may be a human intervention triggering alarm as well.

The running and operation of the application on the mobile communication device has to be and it is possible to initiate and execute in line with the system and character of the device. This means that in most of the cases active user intervention is required for starting sending of signals from the mobile communication device to the receiving party.

It is evident that in life there are a number of situations, events, where it cannot be expected from a user to implement an operation of this type, or simply the user is not in a situation where he can carry out the necessary steps, and in this case it is in vain that such a signaling application is installed on the mobile communication device, the signal will not get to the

selected addressee/addressees or receiving party.

It is easy to realize that a deficiency of this kind in an extreme case may be even fatal. Therefore it is indispensable to have a technical solution, which - exploiting the advantages of the current mobile communication devices - allows secure forwarding of alarming or emergency signals to a target, whenever it is needed.

US 8,249,547 Bl shows a possible solution to eliminate the above mentioned problem, describing an independent portable personal emergency alarming device. The device has a wrist-watch like design and it is practically equipped with all the functions of an independent mobile communication device and it is complemented with an operating element, which is suitable for triggering an immediate alarm. It is a disadvantage of this solution that this is an additional new separate device, which the user has to carry with himself and he has to operate it, and this makes the everyday life of the user more complicated, though not significantly.

US 2005/0287981 proposes another type of solution, which refers to a mobile phone personal alarming device. This device is designed as an accessory separable from the mobile phone, which has its own energy supply. The user may carry this accessory independently as well. There are small performance transceiver units communicating with each other, designed into the device and the mobile phone. If the two parts, that is, the mobile phone and the device get beyond a pre-defined distance from each other, an alarming signal appears in both parts, which may be acoustic and/or visual, and if the user does not acknowledge the alarm within a pre-defined time after the appearance of the alarming signal, the mobile phone with the aid of the application installed on it may send a alarming signal to pre-defined addressees. It is a main deficiency of this solution that when they designed it they wanted to primarily prevent the danger of losing the mobile phone or having it stolen or to make this perceivable, and they did not consider it to be a main task that the alarm initiated by the user should get to the appropriate place.

Our invention is based on the recognition that today's mobile communication devices nearly without any exception are suitable for being supplemented with an external unit, which does not basically change the character and the properties of the communication device, and which does not require any additional attention from the user, and which is suitable for initiating sending of a signal automatically in definable cases towards the mobile communication device, without any user intervention or control.

Said task set has been solved by a wireless signaling device according to the features of claim 1. Several preferred embodiments of the device according to the invention have been listed in the dependent claims.

It is to be mentioned among the important advantages of the wireless signaling device according to the invention that by the aid of the communication solutions that are applied within the signaling device it is possible to pair it with an arbitrary portable or mobile communication device in such a manner that it will modify the dimension and use of the latter device only up to a negligible extent. Therefore the user will not feel the existence and using the signaling device with his own portable communication device, e.g. smartphone, uncomfortable or disadvantageous. It is another additional advantage that in a pre-definable and recordable manner and in the case of the occurrence of certain circumstances it may be ensured with the aid of the signaling device that the prevailing signal is forwarded to the appropriate destination, and it is an important advantage that in this case the destination may already be not exclusively a dedicated equipment or network device of a service provider, but with bypassing these latter devices, those other communication devices that are located within the vicinity of the signaling device issuing the signal are also able to receive the signal, and to introduce the measures required based on the signal received.

The invention will become apparent in more detail in the following description with the aid of the attached drawing showing an exemplary embodiment of the wireless signaling device according to the invention. In the drawings:

Fig. 1 is a block diagram of a possible and advantageous embodiment of the wireless signaling device according to the invention;

Fig. 2 is a more detailed schematic diagram of the signaling device of Fig. 1;

Fig. 3 is a possible embodiment of the signaling device shown in the previous

Figures; and

Fig. 4 is a schematic view of the operation and use of the signaling device according to the invention.

Fig. 1 shows a possible and advantageous embodiment of the wireless device according to the invention that is built up from the parts indicated in Figure. A signaling device 1 comprises in the simplest case a communication unit 2 that ensure wireless communication, a power supply unit 3 and an actuator 4. The communication unit 2 in this exemplary embodiment is a unit capable of Bluetooth connection and communication, and it also operates as a control unit,

and it may be also implemented using an integrated circuit of type BLE112-A shown in Fig. 2. However, for a person skilled in the art it is obvious that as communication unit 2 any such single integrated circuit or even a more complex partially integrated unit may be also applied, which is suitable for carrying out the task of conducting the communication required with the portable communication device, not shown in the Figures. This communication unit 2 may be -beyond a Bluetooth device - a module that operates according to the Wi-Fi or Zigbie standards, but circuits that correspond to newer recommendations or standards may be also used.

The power supply unit 3 may be also implemented in the simplest case with a battery or a rechargeable battery: as regards its technical parameters - in a manner that is obvious for a person skilled in the art - it has to be able to supply the communication unit 2 with energy for an expectable duration. The power supply unit 3 may be implemented in the form of an electromagnetic charger module, without any galvanic connection. As an actuator 4 in the simplest case a press button or a switch can be used, the task of which is exclusively to start the operation of communication unit 2; however in the case of more complex signaling devices the actuator may be also used to eliminate the operation of the wireless signaling device, if required, whenever it is necessary due to the circumstances, e.g. on an airplane, etc.

According to another advantageous implementation actuator 4 or the immediate vicinity of actuator 4 is of a design that provides protection against incidental operation. This may be implemented for example by dividing the actuator 4 into two parts, in which case only the simultaneous operation of both parts will result in the operation of actuator 4. However, actuator 4 may be supplied with a cover, which in the course of normal operation prevents the incidental activation of actuator 4. In this case the force applied by the user deactivates the protective cover.

In the case of a more complex embodiment than the basic level wireless signaling device shown in the block diagram of Fig. 1, which may be used, when the portable communication device does not have an own GPS receiver, the signaling device 1 contains a GPS module 5 as well. This GPS module 5 is in connection with the communication unit 2, and it automatically supplies the communication unit 2 with the actual GPS co-ordinates and data of the signaling device and in the basic case with the co-ordinates and data of the portable communication device that is attached to it.

The GPS module 5 may be also complemented with an energy utilization controlling module as well - known to a person skilled in the art - which cannot be seen in the Figures and which for example will deactivate the GPS module 5, while the user does not operate actuator 4, thus reducing the stand-by status performance provided by power supply unit 3 this way as well.

Fig. 3 presents a possible implementation of the signaling device outlined in Figures 1 and 2, which is implemented as a case 6 of a portable communication device, e.g. a mobile smartphone. The communication unit 2, power supply unit 3, actuator 4 and GPS module 5 are installed into this case 6 in a way that protects them from environmental impacts. Naturally, the power supply unit 3 is arranged in the case 6 in a way that allows carrying out its replacement in a known manner. The method of arrangement also has to protect the battery or rechargeable battery of power supply unit 3 from being exposed to water, contamination, etc. Similarly, actuator 4 is a press button incorporated into the case 6, which press button is not shown in the drawing, however, it has a wired connection with communication unit 2 implemented in a known manner, depending on communication unit 2 applied. The press button used as an actuator 4 is also integrated into the case 6 in a way that protects it from outer impacts in such a manner that the user is able to operate actuator 4 without any problem and delay, and at the same time the actuator 4 is separated from the environment that is outside the material of the case 6, that is, it has a design that provides protection against dust, contamination and water.

According to another possible embodiment of the signaling device according to the invention, the signaling device connected to the mobile communication device has a galvanic connection with this latter one, and in this case the power supply unit 3 is the power supply of the mobile communication device, moreover, the communication unit 2 may be made capable of having instead of a wireless connection - or in addition to it - a wired connection as well with the mobile communication device, e.g. through its charging/interface connector. It is also possible to set the equipment in such a manner that communication unit 2 of the signaling device according to the invention should issue a signal not only when it is operated by actuator 4, but for example also when the signaling device according to the invention is moved away supposedly unintentionally from the mobile communication device. This way the risk of its becoming lost is reduced.

In Fig. 4 the operation of the signaling device according to the invention may be observed. On the diagram of the Figure an user 7 is shown who possesses and uses the wireless signaling device according to the invention, and also the arbitrary portable mobile communication

device, e.g. a smartphone is shown. The smartphone of the user 7 is connected to either a mobile phone network 8 and/or e.g. through a Wi-Fi connection to the Internet 9, and a dedicated server 10 of the service provider of the application running on the smartphone is also connected to the Internet 9. Both the mobile phone network 8 and the Internet 9 is in contact with such persons 11, or the mobile communication device of such persons 11, to which a wireless signaling device according to the invention is attached in a similar manner, and which provides notification through an application that does not belong to the subject matter of the invention, whenever user 7 issues a signal with his own wireless signaling device.

According to an additional option the application running on the portable communication devices is designed in a way that it ensures a possibility for the case when there is a lack of coverage or internet connection that the portable communication devices supplemented with a wireless signaling device according to the invention or with an operation ensuring application going through the server 10 of the service provider through the Internet should be able to establish direct connection with each other. This variant has that significant and so far unknown advantage that in the case of an emergency situation, when the wireless signaling device according to the invention is operated, those persons 12 located in the vicinity or immediate vicinity of the user 7, who may even not have such a wireless signaling device, should receive immediate and direct notice, depending on the application in such a manner that in addition to the emergency signal they will be also informed about the exact location of the signaling device sending the emergency signal, thanks to the GPS module 5 mentioned earlier, and this way help may be provided without any delay.

Therefore an additional advantage of the device proposed can be seen in that in territories, where mobile phone coverage is weak or deficient, forwarding an alarm signaling to others does not become impossible, since the portable communication device may be connected directly with the aid of wireless communication technologies to other portable communication devices located within the territory, and the alarm signal issued may be forwarded to these devices e.g. through Wi-Fi, Bluetooth, etc. connection.
