Description

Continuous recording management system

The present invention relates to the field of electronic media recording devices, more particularly that of electronic devices for audio-visual recording by a user.

A user wishing to be able to keep a memory of an event, of a lived moment, of a visited place, or of any important moment of his life has at his disposal several solutions to capture and record these moments of his life. Thus, the user can use an electronic device such as a video camera, a camera or a tape recorder type audio recorder to capture sounds or images corresponding to an event. The user, through these different electronic devices, can capture, record and store memories of these events in the form of data, typically audio and / or video data. The user, by viewing or listening thereafter this data corresponding to an event can remember this event.

These electronic devices, however, have disadvantages. Thus, it is necessary to trigger in advance the capture and recording by these electronic devices moments for which we wish to keep a memory. Once a moment lived or passed, it is too late to trigger a recording of that moment by the electronic device. It is therefore necessary to anticipate, which is not always possible. It is thus often difficult to know a priori if a future event is worth recording. Another disadvantage is that a user of such an electronic capture device must often handle the same electronic device to properly capture the event. A user of a camera or a camera must thus take a step back from the scene he wants to capture, the user of an audio recorder must potentially handle and guide the electronic capture device or microphones, so that these users do not fully participate in the event the time of the capture, they do not live it fully. Often, it is also worth noting that the presence of electronic capture devices disrupts the event, the people participating in the event may react differently to a camera or they realize that what they say is in the process of to be registered.

It is desirable to overcome these disadvantages of the state of the art. The invention relates to a data recording system for a user, the system comprising an electronic recording device comprising at least one sensor, an input device, a communication interface and a storage unit, the electronic device of recording being adapted to continuously record time stamped data from each sensor and at least one timestamp of an input made by the user on the input device, an electronic transfer device comprising a first communication interface allowing a connection with the electronic recording device and a second communication interface for connection to a server, the electronic transfer device being adapted for, when the electronic recording device is connected to the electronic transfer device, transferring the recorded data and at least one timestamp of the seizure on the electronic recording device to the server, the server comprising a storage unit and a communication interface, the server being adapted to process data received in association with the time stamp of the entries to determine a period to keep corresponding to the timestamp received, the corresponding data of the continuous recording being recorded, an application executed by an electronic device, adapted to connect to the server and allowing the user to view the data transferred to the server and processed by the server.

Advantageously, the electronic recording device continuously records sensor data such as microphones, as well as the timestamp of user input times, these entries being indicative of the period of continuous recording to be kept. In order to minimize the complexity, and therefore the cost and the energy consumption of the electronic recording device, the processing phase, which makes it possible to record the periods to be conserved, is carried out a posteriori by the server from the continuously recorded data, transferred to the server, and the timestamp of the entries.

According to a complementary embodiment of the invention, the input made being of a first type, the period to be preserved corresponds to a first duration prior to the time of entry.

Advantageously, the input can be performed after the period that the user wishes to keep. According to a complementary embodiment of the invention, the input being made being of a second type, the period to be preserved corresponds to the first duration prior to the time of entry and to a second period subsequent to the time of entry.

Advantageously, a second recorded duration allows the user to pronounce keywords to facilitate the replay or archiving of the periods retained.

According to a complementary embodiment of the invention, the first duration is proportional to the time of a pressure on the input device.

According to a complementary embodiment of the invention, the second duration is proportional to the time of a pressure on the input device.

According to a complementary embodiment of the invention, when the electronic recording device detects at least a second input, indicative of a second period to be conserved, performed in a time less than a predefined time following the first input, indicative of the first period to remain, then a third period, beginning when the first period begins and ending when the second period ends, is kept in place of the first and second periods.

The invention also relates to an electronic recording device comprising at least one sensor, an input device, a communication interface and a storage unit, the electronic recording device being adapted to continuously record time stamped data from each sensor and at least one timestamp of an input made by the user on the input device.

The invention also relates to a computer program, which can be stored on a medium and / or downloaded from a communication network, in order to be read by a processor. This computer program includes instructions for implementing the steps mentioned below, when said program is executed by the processor. The invention also relates to an information storage medium comprising such a computer program.

According to a first embodiment of the invention, the electronic recording device 100A comprises a single box 105 A. Additionally, the electronic recording device 100A further comprises a cord 110A. Said cord 110A is particularly useful for allowing the wearing of the electronic recording device 100A around the neck, such as a pendant. The cord 110A may also allow the connection of the housing 105A to a secondary housing 115A, said secondary housing 115A may include an additional battery.

According to an alternative embodiment of the invention, the electronic recording device 100B comprises two casings 105B1 and 105B2. Both boxes 105B1 and 105B2 can be connected by a 110B cord or by wireless technology. The electronic recording device 100B may take the form of a pair of earrings, each case 105B1 and 105B2 being an earring.

In order to improve the aesthetics of the electronic recording device 100, each housing 105A, 105B1 or 105B2 may comprise fixing means, which fastening means allow the attachment of an aesthetic shell to said housing. The shell has aesthetic properties (choice of material, eg wooden shell, choice of color, choice of shape, etc.) and a complementary fastening means to that of the housing 105 A, 105B1 or 105B2. The fixing means are for example of the "clip" type. It is thus possible to "clipper" a shell on the housing 105 A, 105B1 or 105B2 to give it aesthetic properties.

A secondary housing 115A, respectively 115B, can be connected to the housing 105A, respectively to the two housings 105B1 and 1B2, via the cord 110A, respectively 110B.

The connection of cords 110A or 110B to a box 105A, 105B1 or 105B2 and to the secondary box 115A or 115B can in this case be achieved via "jack" type connectors or "mini / micro USB" (Universal Serial Bus in English). In particular, the user can choose to wear the electronic recording device 100A as a pendant by connecting the cord 110A to the casing 105A. Alternatively, the casing 105A may comprise a fixing device in order to be fixed for example on a clothing, like a brooch.

The electronic transport device 205, for example, takes the form of a housing for accommodating the electronic recording device 200 and to carry it thus without damaging, while reloading it.

The electronic transfer device 210 is intended to allow to electrically recharge the electronic recording device 200 as well as to allow the electronic recording device 200 to be connected to the server SRV 230. The electronic transfer device 210 thus serves as an intermediary between the electronic recording device 200 and the SRV server 230 for transferring the content recorded by the electronic recording device 200 to the SRV server 230 and for transferring the configuration parameters of the electronic recording device 200 from the SRV server 230 to the electronic recording device 200.

The server SRV 230 comprises at least one processor, a communication interface allowing the establishment of a connection to the network of NET communication 220 and a storage unit or access to a database for storing data.

The electronic device SMART 240 is for example a computer, a tablet or a mobile phone type "smartphone". The SMART electronic device 240 executes an application allowing in particular access to the online service hosted by the server SRV 230. Said application can be pre-installed on the SMART electronic device 240. Said application can be downloaded from an application store of "iTunes" type "Apple" or "Play" from "Google". The application executed by the electronic device SMART 240 makes it possible to manage the recordings made by the electronic recording device 200 and transferred, via the electronic transfer device 210, to the online service hosted by the server SRV 230. This application enables thus to consult the recorded contents, but also to manage and parameterize the system described in the present invention. This application includes a GUI type interface (Graphical User Interface in English) to facilitate the consultation and management of the recordings made and transferred to the server SRV 230. A user of this system must therefore install said application and configure an access to the online service hosted by the server SRV 230 to then be able to consult and manage its recordings made by the electronic recording device 200, once they have been transferred from the electronic recording device 200 to the server SRV 230 via the electronic transfer device 210. Likewise, certain configuration parameters of the present system can be set via a graphical interface of the application by the user and then transferred from the SRV server 230 to the electronic device. 200, via the electronic device tronic transfer 210.

This digital data is recorded on the STCK storage unit 305 in a time-stamped manner. This allows in particular a subsequent synchronization of the data from the different sensors during a restitution.

The electronic recording device 300 may comprise one or more magnets or ferromagnetic parts. The purpose of these magnets or ferromagnetic parts is to enable positioning, or even fixing, of the electronic recording device 200 on or in the electronic transfer device 210 or the electronic transport device 205.

Fig. 6 schematically illustrates a timing chart for processing a continuous record of a media, according to an embodiment of the present invention. The electronic recording device 100, identical to the electronic recording devices 200 and 300, continuously and time-stamped the digital data corresponding to the signals from the MIC microphones 320, 321, as well as possibly signals from other CAPT sensors. 330, such signals from a GPS sensor or heart rate monitor. This data is stored in the STCK storage unit 305, possibly without any processing in order to reduce the power consumption of the electronic recording device 100. Thus, if the electronic recording device 100 has two MIC microphones 320 and 321, two Data files corresponding to each signal picked up by each microphone 320 and 321 will be created, the corresponding data being continuously recorded on the storage unit STCK 305 and time stamped. According to one embodiment of the invention, when the storage space of the STCK storage unit 305 is filled, then the continuous recording terminates. The electronic recording device 100 may indicate the end of the recording by a predetermined signal transmitted via the output device OUT 312. According to another embodiment of the invention, when the storage space of the recording unit STCK 305 storage is full, the oldest data is overwritten by the most recent data. Possibly, some old data is preserved from overwriting if it is indicated to be kept, as explained below.

The axis 600 represents the axis of time, corresponding to a continuous recording of one or more signals coming for example from the MIC microphones 320, 321. These signals are recorded continuously and time stamped by the electronic recording device 100. A and B correspond to entries by a user of the electronic recording device 100 on the input device IN 311. A corresponds, for example, to a pressure on the input device IN 311 of the press-button type. B corresponds for example to two successive presses on the input device IN 311. In the case where the electronic recording device 100 detects an entry A by the user, then the electronic recording device 100 records the time stamp corresponds to the time of the entry A. This time stamp is recorded in the storage unit STCK 305. The entry A by the user means that the signals recorded previously at the time of the entry A must be preserved, and this by going up of a duration D in the past. In other words, after detection by the electronic recording device 100 of an input A by the user, the electronic recording device 100 retains a period 601 of the recordings of the signals, the period 601 corresponding to a predetermined duration D, possibly depending on a context as explained below, the period 601 being just prior to the time of the seizure A. Said still otherwise, the period 601 conserved is defined as having a duration D and ending at the moment of the detection of the From the user's point of view, the period 601 corresponds retroactively to the duration D prior to the input A. Note that according to one embodiment, the duration D is proportional to the time of the pressure on the device. input IN 311 when the input A is done by the user. According to the embodiment of the invention, the step of preserving the period 601 can be carried out in different ways. The period 601 can be copied from the continuous record and stored on the storage unit STCK 305. Alternatively, the electronic recording device 100 can keep the time stamp of the input A and the duration D, so that to be able to determine later the period 601 from the continuous recording. In the case where the electronic recording device 100 detects an input B on the input device IN 311, that is to say for example a double pressure, then a period 602 is retained. This period 602 corresponds to a duration D, prior to the moment of the entry B, followed by a duration M, subsequent to the moment of the entry B. The user can say aloud during this period M key words. A record of the keywords is thus done. This duration M may be proportional to the duration of pressure on the input device IN 311 during the second support by the user. This duration M can be of a predetermined minimum duration. As for the retention of the period 601, the data corresponding to the period 602 can be copied and stored on the storage unit STCK 305 or only the time stamp of the time of the entry B and the durations D and M are preserved in order to be able to determine subsequently, from the continuous recording, period 602. Fig. 7 schematically illustrates a chronogram for processing a continuous recording of a medium, according to a complementary embodiment of the method previously illustrated in FIG. 6. In the case illustrated in FIG. 7, the electronic recording device 100A or 100B detects two inputs B1 and B2, the inputs B1 and B2 corresponding to the input B described above. If the time between the entry B2 and the entry B1 is greater than a predefined time G, then each entry B1 and B2 gives rise to the retention of a corresponding period 701 and 702, each period 701 and 702 being similar to the period 602. illustrated in FIG. 6. In the opposite case, that is to say if the entry B2 is made in a time less than the predefined time G after the entry B1, then the electronic recording device 100A or 100B retains a period 703 instead of the periods 701 and 702. The period 703 is defined as a period beginning when the period 701 begins and ends when the period 702 ends. Thus, when the user of the electronic recording device 100 makes successive entries in a time G, the system determines that the periods to be kept correspond to the same event, and the periods 701 and 702 to be preserved are somehow merged into one. a single period 703. That is, period 703 covers periods 701 and 702.

Fig. 8 schematically illustrates a method of processing a continuous recording of a medium, according to a complementary embodiment of the method previously illustrated in FIG. 7. In the case of FIG. 8, the electronic recording device 100 A or 100B detects three inputs B3, B4 and B5, the inputs B4 and B5 being performed in a time G after the first input B3. In these cases, the three periods 801, 802 and 803 corresponding to the three periods to be retained after the entries B3, B4 and B5 are kept in a single period 804. The period 804 is defined as a period beginning at the beginning of the period. first period 801 and ending at the end of the last period 803. Note that, as in the case illustrated in FIG. 7, the timestamp of the moments of the entries, here B3, B4 and B5, are preserved, as well as the durations M associated with each entry B3, B4 and B5.

The cases illustrated in FIG. 7 and 8 can be transposed with entries A, or a mixture of entries A or B. The difference is that an entry A does not trigger the retention of a duration M after the time of entry A. Fig. 9 schematically illustrates an algorithm of a process for processing a continuous recording of a medium, according to a particular embodiment of the present invention.

Step 901 corresponds to the commissioning of the electronic recording device 100A or 100B. The commissioning can be caused by a predetermined input on the input device IN 31 1, for example a long press. The setting of the electronic recording device 100A or 100B is then retrieved from the memory MEM 302 or the storage unit STCK 305.

In a step 905, the electronic recording device 100 A or 100B starts the continuous and time-stamped recording of the signals coming from the MIC microphones 320, 321 and potentially of any signal coming from a CAPT sensor 330. The user, via the application executed by the SMART electronic device 240, can configure the setting to decide which signals are recorded. The signals are recorded continuously and time-stamped in the STCK storage unit 305. Each signal can have a dedicated storage space within the storage unit STCK 305, where the different signals can share the space. total of the storage unit STCK 305. According to one embodiment of the invention, the electronic recording device 100 A or 100B interrupts the recording when the storage unit STCK 305 is filled. According to another embodiment of the invention, when the STCK storage unit 305 is filled, the electronic recording device 100A or 100B records the new data on the oldest data, while preserving the data being indicated as to keep, that is to say the data corresponding to periods to keep. When there is no longer any data not indicated as being to be kept, either the electronic recording device 100A or 100B terminates the recording, or the data indicated to keep the oldest are deleted first. to continue recording. The electronic recording device 100A or 100B may in the latter case indicate that it is overwriting data corresponding to periods to be preserved by a particular return on the output device OUT 312.

In a step 910, the electronic recording device 100A or 100B detects that the user makes an entry on the input device IN 311. If the input device IN 311 is a push button, the input made on this device can be of different type, for example a simple support (input A for Fig. 6) or two successive presses (entry B for Fig. 6, entries Bl and B2 for Fig. 7 and entries B3, B4 and B5 for Fig. 8).

In a step 915, the time of the entry is recorded in the storage unit STCK 305. In other words, a time stamp of the detected entry is stored in the STCK storage unit 305. The electronic recording device 100 A or 100B can record with Γ timestamp the type of input (for example input A or B), as well as the duration D and the duration M corresponding to the period to be kept. This information makes it possible in particular for the electronic recording device 100A or 100B to recognize the data recorded on the storage unit STCK 305 to be preserved. This is particularly useful in the case where the continuous recording is done by overwriting the old data, since the electronic recording device 100A or 100B, from the timestamps and durations D and M, can determine the data not to be recorded. overwrite as corresponding to periods to keep.

According to one embodiment of the alternative invention, the electronic recording device 100 A or 100B copies directly from the continuous recording the data corresponding to a period to be kept. Thus, a new file corresponding to the period to be kept is created. This alternative consumes more storage space on the STCK 305 storage unit but facilitates the management of the continuous recording of data from the MIC 320, 321 or CAPT 330 microphones, which can then operate continuously on a fixed memory space of the STCK storage unit 305 according to a FIFO principle ("First In, First Out" in English), without risk of overwriting data corresponding to a period to be kept. Indeed, according to this alternative, the data to be kept are directly copied into one or more separate files.

The optional step 920 corresponds to a detection by the electronic recording device 100A or 100B of an input B, as illustrated in FIGS. 6, 7 and 8. In this case, a recording of a duration M is performed after the moment of the input.

In a step 925, the electronic recording device 100 A or 100B determines whether, for a duration G after the detection of the input made during step 910, other inputs are made on the input device IN 311 by the user. .

If this is the case, in a step 930, the electronic recording device 100 A or 100B records in the storage unit STCK 305 information indicating that, for example, a period 703 is to be kept in place of periods 701 and 702, or that a period 804 is to be kept in place of the periods 801, 802 and 803. In other words, a period beginning at the same time as the period to be retained indicated by the first entry (detected during the step 910) and ending at the same time as the last period to keep indicated by a detection of an entry during the duration G is retained instead of the different periods corresponding to the different entries.

According to an alternative embodiment of the invention, the duration G is calculated as beginner at the time of the last input detected by the electronic recording device 100 A or 100B. Thus, each detected entry resets the duration G during which the periods to be preserved are merged into a single period.

The electronic recording device 100A or 100B repeats these different steps as long as the continuous recording is functioning.

The process terminates in a step 935, possibly because the storage space of the STCK storage unit 305 is full, because the BATT battery 306 is exhausted or because the user turns off the electronic recording device 100A or 100B.

Thus, by the method previously described, the electronic recording device 100A or 100B has a continuous record as well as timestamps of the periods to keep.

In order for these recordings to be exploited by the user through the application executed by the SMART electronic device 240, the electronic recording device 100A or 100B must be connected via the electronic transfer device 210 to the online service hosted by the SRV 230 server.

The electronic transfer device 210 allows the positioning of the electronic recording device 100A or 100B within it to allow the electric recharging of the battery BATT 306. The respective positioning of the two devices can be facilitated by the presence of magnets or parts When the two devices are correctly positioned, the INDU 512 induction charging device is correctly positioned to power the RECE 318 receiver in order to recharge the BATT 306 battery. Similarly, a wireless connection can be established between the receiver and the receiver. NET 310 communication interface and the NET1 communication interface 510. For example, a connection of "Bluetooth" or "Bluetooth Low Energy" type can be established. Note that according to one embodiment of the invention, the electronic device 100 A (or 100B) and the electronic transfer device 210 do not establish a wireless connection but have connectors, which when positioned face-to-face, allow the establishment of a wire connection, such as a USB connection. The electronic transfer device 210 establishes a connection with the server SRV 230 through the communication interface NET2 511. Once the electronic transfer device 210 is connected to the electronic recording device 100A or 100B, the electronic transfer device 210 can access the contents of the STCK storage unit 305, i.e. the data recorded by the electronic recording device 100A or 100B, and retrieve them for storage on its own STCK storage unit 505. If a connection is also established with the SRV server 230, the electronic transfer device 210 can directly transmit the recorded data to the server SRV 230. The STCK storage unit 505 of the electronic transfer device 210 thus serves as a temporary storage unit. before transmission to the server SRV 230 of the data recorded by the electronic recording device 100. A united identifier that associated with the electronic recording device 100, such as a network address associated with the NET communication interface 310, can be associated with the data recorded by the electronic recording device 100. Thus, an electronic transfer device 210 can be shared or used by several electronic recording devices 100A or 100B. The unique identifier associated with each electronic recording device 100 makes it possible to identify the origin of the data, that is to say what electronic recording device 100A or 100B is at the origin of the data recording. .

Once the SRV server 230 has received the data recorded by the electronic recording device 100A or 100B, the SRV server 230 processes the received data. In the event that the server receives data corresponding to a continuous record and the markers or timestamps of the entries made by the user, the SRV server 230 extracts from the file corresponding to the continuous record, according to the markers or timestamps received, the different periods to keep. Thus, from the time stamp of a moment, for example that of the entry B, and durations D and M, possibly deduced from the context, the server SRV 230 extracts the file of duration equal to the sum of the durations D and M corresponding to the period 602 to be retained. The durations D and M associated with each time stamp can be recorded in association with each time stamp, especially if these durations are determined according to the duration of a pressure on the input device IN 311. The data processing may comprise steps of noise filtering, voice recognition, compression of the data, or the application of any improvement algorithm of a signal.

The server SRV 230 can process the recordings of the stored periods so that the durations M retained are placed before the associated durations D, so that the key words uttered by the user during the durations M are restored before the corresponding duration D when a replay of a conserved period.

According to an alternative embodiment of the invention, the previous steps performed by the server SRV 230 are performed by the electronic transfer device 210. In a complementary manner, the electronic transfer device 210 and the server SRV 230 are one and the same. electronic device.

According to a complementary embodiment of the invention, the duration D and / or M, in the absence of maintaining the input device IN 311 to indicate a particular duration, is defined according to a context. A context corresponds to predetermined criteria. Different predetermined criteria may be predefined or defined by the user, in particular via the parameterization option of the application executed by the electronic device SMART 240. Thus, the criteria may be temporal, with for example a first context corresponding to the days of work (Monday to Friday for example) and a second context corresponding to weekends (Saturday and Sunday for example). For each context, a different duration D and / or M can be defined. A context can also be defined dynamically by creating an association between the application executed by the SMART electronic device 240 and a user's calendar management application executed by the same SMART electronic device 240. Thus, a context "in meeting "can be defined, corresponding to times when the user's calendar indicates that the user is in a meeting.

According to a complementary embodiment of the invention, step 915 is performed autonomously by the electronic recording device 100A or 100B, according to a criterion for triggering the recording of a time stamp. That is, the electronic recording device 100A or 100B can record a time stamp indicating a time to be maintained in the absence of detection of an input on the input device IN 311. case if the electronic recording device 100A or 100B is configured to record a timestamp when a parameter of a CAPT 330 sensor reaches a predetermined value. Thus, the electronic recording device 100A or 100B can record a timestamp automatically when a heart rate monitor CAPT 330 sensor determines that the measured heart rate of the user exceeds a predefined threshold.

The various configuration parameters of the electronic recording device 100A or 100B can be set by the user via the application executed by the electronic device SMART 230. These parameters are recorded by the server SRV 230, and are sent to the electronic device. recording 100 when it connects to the server SRV 230, including to send the data to keep.

According to one embodiment of the invention, the electronic recording device 100A or 100B takes the form of glasses comprising one or more camera-type CAPT sensors 330, making it possible to film what the user wearing the glasses, potentially three dimensions or a wide field of view according to the positioning of the cameras, and comprises two MIC microphones 320 and 321, each being positioned in an opposite branch of the glasses.

According to a complementary embodiment of the invention, the microphones 320 and 321 comprise a molding of the user's ears in order to achieve binaural sound capture.

The application executed by the electronic device 240 allows the user to consult the stored records and thus relive the corresponding events. The server SRV 230 can determine via voice recognition technology the key words uttered during the durations M in order to automatically index the durations conserved, and thus allow textual searches by keywords via the application. According to a complementary embodiment of the invention, the server SRV 230 can analyze the data corresponding to the periods conserved, the durations D or all the received data. In particular, the SRV server 230 may use a speech recognition technique to automatically determine a keyword indexing of the received recordings. Automatic indexing of the periods to be preserved is thus performed by the server SRV 230. The indexing may also relate to data of the continuous recording which is not indicated as being to be kept. According to a complementary embodiment of the invention, during the automatic indexing by a technique of voice recognition, when the server SRV 230 recognizes a key word, the server SRV 230 can automatically create a period to keep corresponding to the moment of detection of the key word.

According to a complementary embodiment of the invention, the server SRV 230 uses a speech recognition technique to determine a context. The server can also use a speech recognition technique to adjust the duration D or the duration M. This is the case for example if the server SRV 230 determines that the duration D or duration M must be adjusted not to cut a speech , or a song, recognized by the voice recognition technique.

According to one embodiment of the invention, the functions of the electronic recording device 100A, 100B, 200, 300 and the electronic transfer device 210, 500 are integrated in the same electronic device. This electronic device can operate differently depending on whether it is connected to a source of external electrical power or not. Thus, the functionalities corresponding to those of the electronic transfer device 210 can only be activated when the electronic device is connected to an external source of electrical power and its battery is charging. This makes it possible to retain the advantages of an electronic recording device that consumes little electrical energy during operation that is not connected to an external energy source, and thus to preserve its autonomy.

Similarly, according to an alternative embodiment of the invention, all or part of the functions of the server SRV 230 can be integrated into the electronic recording device 100A, 100B, 200, 300. The electronic recording device 100A, 100B , 200, 300 can then activate these features only when connected to an external power source to preserve its autonomy. In other words, according to this alternative embodiment of the invention, all the steps of the method illustrated in FIG. 9 can be performed by the electronic recording device 100A, 100B, 200, 300, the steps indicated as being performed by the server SRV 230 then being performed by the electronic recording device 100A, 100B, 200, 300 that when said electronic recording device 100A, 100B, 200, 300 is connected to an external power source. The activation can also be done on demand, for example via a predetermined input from the user on the input device IN 311. Activation can also be done when connecting the SMART electronic device 240 to the electronic recording device 100A, 100B, 200, 300 integrating the functionality of the server SRV 230.
