## Background
This application is based on and claims the benefit of Taiwan Application No. 100140067 filed Nov. 3, 2011 and Taiwan Application No. 101123556 filed Jun. 29, 2012, the entire disclosure of which is incorporated by reference herein.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention involves a method of procurement, especially regarding the method which enables an electronic apparatus to automatically establish Bluetooth connectivity and wirelessly obtaining external data.
2. Description of the Related Art
There are many different electronic apparatus on the market that can assist users to measure and record data. In FIG. 1A and FIG. 1B are examples of the blood pressure machine and electric meter of related art.
Generally, blood pressure machine 1 is used to assist users to measure the systolic blood pressure, diastolic blood pressure, and pulse, etc., and the measured values would be shown on a display screen 11 of the blood pressure machine 1. The user can see the measured values from the display screen 11 and to write it down for record. Electric meter 2 is to measure the total electricity usage of the user's home, and the measured value will be shown on a meter readout 21. Using the meter readout 21 the user can know the current electric usage amount, and electric utility employee can calculate the electric fee based on the value.
Take the blood pressure machine 1 for example, after the medical staff uses the blood press machine 1 to take blood pressure for the patient in the hospital, staff would record manually the measured value onto the patient chart. As your can see, there could be hand written mistake, human error introduced. Furthermore, if more than one blood pressure machine 1 is used simultaneously to concurrently measure multiple patients at same time, this increases the chance of higher likelihood of hand written mistakes.
In recent years there are many new types of measuring tools on the market, for example the blood pressure machine 1 would have embedded Bluetooth connectivity capability. Hence, after the medical staff uses the blood pressure machine 1 to take blood pressure reading from the patient, a mobile apparatus such as Personal Digital Assistant (PDA) can be used to establish Bluetooth connection to the blood pressure machine 1 and obtain the blood pressure data wirelessly with the blood pressure machine 1. In this way human errors can be avoided.
However, it's not an easy task to establish Bluetooth connection between two apparatus, as it incorporates the following steps: 1. User needs to manually activate Bluetooth transfer capability on the PDA; 2. User needs to broadcast the PDA's Bluetooth signal to search the surrounding area for Bluetooth capable apparatus; 3. PDA will show a list of connectable Bluetooth apparatus in the area for user to choose from; 4. User must identify the target blood pressure machine 1's apparatus name or serial number and select it to make connection; 5. PDA will make Bluetooth connection with the selected blood pressure machine 1; 6. Once Bluetooth connection is established successfully, PDA will retrieve the blood pressure data from the blood pressure machine 1; 7. User will fill in the retrieved data into a corresponding field on the PDA.
From the above description, there are many troublesome and manual steps the users must take to make a Bluetooth connection. Furthermore, if the medical staff has multiple units of the same brand and model of the blood pressure machine and simultaneously in use to take blood pressure readings from different patients, when the PDA is searching for nearby Bluetooth apparatus, there will be multiple identical model name or serial number shown in the list. This would cause selection error and recording error as medical staff would have difficult time identifying correctly which target on the PDA's list correspond to the actual blood pressure machine. As such, using the above method to obtain the Bluetooth data will result in user annoyance.
There should be a new method and an apparatus using the new method that will enable the user to retrieve external data via Bluetooth easily, minimize complicated manual steps, and also to avoid human and apparatus selection errors.

DETAIL DESCRIPTION OF THE INVENTION
Referring now to the drawings illustrating a preferred embodiment of the invention, detailed description as follows:
Please refer to FIG. 2 which illustrates a preferred embodiment of the invention. The invention mainly comprises of an electronic apparatus 3 that utilizes its application program A1 to wirelessly obtain data from external device; the electronic apparatus 3 itself comprises of a display screen 31, a non-contact data obtaining component 32, a microprocessor component 33, a Bluetooth transmitting component 34, and a memory component 35. The microprocessor component 33 is electronically connected to the display screen 31, the non-contact data obtaining component 32, the Bluetooth transmitting component 34, and the memory component 35, and the application program A1 resides in the memory component 35.
The non-contact data obtaining component 32 primarily employ non-contact method to obtain external data (e.g. External message 51 ̃56 as illustrated in FIG. 5 to FIG. 9 will be explained below using the external message 51 as example). Its worth mentioning that the electronic apparatus 3 can have at least one control button 36 electronically connected to the microprocessor component 33 allowing the user to press on the control button 36 to activate the non-contact data obtaining component 32 to obtain the external message 51. Or the non-contact data obtaining component 32 can be configured to start automatically when the application program A1 is running, and the non-contact data obtaining component 32 set to run as a background process. As such, the user will not need to manually press the control button 36 to start the non-contact data obtaining component 32. In addition, in this embodiment, the display screen 31 can be of touch screen type so the control button 36 function can be combined onto the display screen 31, but not limited thereto.
After the external message 51 is obtained, it will be sent to the microprocessor component 33, the microprocessor component 33 will determine if the external message 51 contains an external device (example of external device 4 as shown in FIG. 5) Media Access Control Address (MAC Address) (example of MAC address 61 as shown in FIG. 5).
The Bluetooth transmitting component 34 will provide the electronic apparatus 3 with a type of wireless transfer capability. Once the microprocessor component 33 successfully received the MAC Address 61 (more specifically the MAC Address of a Bluetooth transmitting component of the external device 4) of the external device 4 via the external message 51, the microprocessor component 33 will activate the Bluetooth transmitting component 34 and automatically establish Bluetooth connection with the external device 4 in accordance with the obtained MAC Address 61. The benefit of this method is to only establish pairing with the known MAC Address 61. The electronic apparatus 3 will only establish Bluetooth pairing connection with the owner of said MAC Address 61 and not search nearby area for connectable Bluetooth devices that user must manually choose from. In other words, the electronic apparatus 3 will know the external device 4 is the target to make Bluetooth connection with, thus user does not need to manually perform selection and settings procedure, and this will greatly minimize the time required for establishing Bluetooth connection.
Primarily this invention is using Bluetooth connectivity as an embodiment, however as long as the transmission and connectivity method can be quickly performed between two devices using this invention's method, would be inclusive and not limited thereof. For example, as long as the external message 51 contains the MAC Address 61 of the said external device 4 and the electronic apparatus 3 obtains the MAC Address 61 of the external device 4, then a direct connection can be made with the external device 4 via ZigBee or WiFi direct or any other transmission protocol without the need to survey all of the surrounding devices and to find the matching target device.
The memory component 35 can store at least one data record sheet P1 and shown on the display screen 31 and the data record sheet P1 mainly comprise of data fields relevant to the data obtained from the external device 4 (explained in the following sections). After the electronic apparatus 3 establish Bluetooth connection with the external device 4, electronic apparatus 3 will automatically obtain necessary data from the external device 4, and the microprocessor component 33 will determine base on the type of device of the external device 4 to open the corresponding data record sheet P1 and fill in the data into a corresponding data field of the data record sheet P1. This will minimize the amount of manual entry of data by the user and thus avoid human errors.
Please now refer to FIG. 3A illustrating a preferred embodiment of the connection process. Firstly, the electronic apparatus 3 uses the non-contact data obtaining component 32 to obtain the external message 51 non-contact wirelessly (step S30), then the microprocessor component 33 will determine if the external message 51 contains the MAC Address 61 of the external device 4 (step S32).
Please also refer to FIG. 5 illustrating a preferred embodiment of the external message obtaining process. In this embodiment the non-contact data obtaining component 32 can be a barcode component 321, and the external message 51 contains barcode data of the MAC Address 61 of the external device 4. More specifically, in this embodiment, the external message 51 is barcode data comprised of the MAC Address 61 of the external device 4 and a Model Code 62, wherein, the model code 62 is used to determine the type of the external device 4 by the electronic apparatus 3 (explained in following section). The above mentioned steps S30 and S32 refer to the barcode component 321 obtaining the barcode data and determine if the content of the barcode data contains the MAC Address 61 of the external device 4. The barcode data can be attached to the surface of outer shell of the external device 4, or shown on the display screen of the external device 4 (not in the figure), but not limited thereof.
The electronic apparatus 3 can also have a light emitting component (not in the figure), for example a flash light, when the electronic apparatus 3 determines that data obtainment failed is due to insufficient environment lighting, the electronic apparatus 3 can automatically activate the light emitting component for light compensation to improve data obtaining success rate. For example, if the nursing staff needs to obtain the data from the patient's blood pressure machine while the patient is sound asleep in the dark room, this will render the electronic apparatus 3 not able to successfully obtain the external message 51 on the blood pressure machine due to lack of ambient light, thus the electronic apparatus 3 can automatically activate the light emitting component as light compensation via the method as described earlier.
Please also refer to FIG. 6, illustrating a second embodiment of the external message obtaining process. In this embodiment, the non-contact data obtaining component 32 can be of a Radio Frequency (RF) component 323, the external message 53 can be stored within a RFID tag, and this external message 53 is comprised of the MAC Address 61 of the external device 4 and the Model Code 62. The RFID tag can be placed anywhere within the external device 4, or attached to the outer surface of the external device 4, and not limited thereof.
The RF component 323 can be activated once the internal application program A1 stored in the electronic apparatus 3 is running, and can continually emit RF signals to search for any RFID tag nearby the electronic apparatus 3. When the user places the electronic apparatus 3 nearby the outer surface of external device 4, the RF component 323 can detect the RFID tag, and establish connection to obtain the external message 53 that is stored within the RFID tag. It's worth mentioning that if data obtainment is processed via the RF component method, this embodiment will not encounter the problem of insufficient ambient lighting issue causing data obtainment failure which requires activation of light emitting component for light compensation, as this RF method is more convenient.
Comparing with Bluetooth technology, RF is a short range transmission technology, the transmitting range is much shorter, thus even when the RF component 323 is continuously operating, while there are many external devices 4 that is nearby the electronic apparatus 3, as long as the distance is not close enough the RF component 323 will not be able to obtain the RFID tag, hence there is no need to worry if the wrong device data is being obtained or repeated data obtained. Moreover, any short range non-contact wireless transmission technology can be used as a method described by this invention, for example Near Field Communication (NFC) or ZigBee, etc. This invention merely uses the RF technology as an embodiment, thus the scope of this patent is not limited thereof.
Please refer to FIG. 7, illustrating a third embodiment of the external message obtaining process. In this embodiment, the non-contact data obtaining component 32 as a camera component 322, the external message 54 primarily as text or graphic image, not limited thereof. From step S30, the electronic apparatus 3 utilizes the camera component 322 to obtain the external message 54 (obtaining the text or graphic message image) and transfer the data to the microprocessor component 33. Then in step S32, the microprocessor component 33 will decode the text and or the graphic image of the external message 54, obtaining the message within the external message 54, and determines if the external message 54 contains the MAC Address 61 of the external device 4.
From the embodiment shown as FIG. 7, the external message 54 comprises of the MAC Address 61 of the external device 4 and the Model Code 62, hence when the microprocessor component 33 decodes the text and or the graphic image, it will obtain the MAC Address 61 of the external device 4 and the Model Code 62.
Please refer to FIG. 8, illustrating a forth embodiment of the external message obtaining process. In this embodiment, the non-contact data obtaining component 32 is a camera component 322. The external message 56 primarily comprised of the MAC Address 61 of the external device 4 and the Model Code 62, which will be referred to as the QR code. In the step S30, the electronic apparatus 3 utilizes the camera component 322 to obtain the QR code, and transmit the data of the QR code to the microprocessor component 33. In step S32, the microprocessor component 33 will determine from the QR code whether the QR code contains the MAC Address 61 of the external device 4.
It's worth mentioning that as long as the external device 4 is within the Bluetooth connectable range of the electronic apparatus 3, it can establish connection with electronic apparatus 3, thus the external message 51 ̃56 may not need to be attached to the outer surface of the external device 4. FIG. 9 illustrates the fifth embodiment of the external message obtaining process. For example, nursing staff in the hospital can carry an information board 560, and the information board 560 can attach many external messages (FIG. 9 shows the external message 56 as example), and each external message 56 contains different MAC Address of individual external device 4. Hence when nursing staff needs to obtain the data from a first external device, staff only needs to use the electronic apparatus 3 to obtain the external message 56 on the information board 560 which corresponds to the first external device and no need to look for the physical external device itself (the external device could be on the desk, on the bed, in the drawer or on the nursing cart, etc.). This will increase the convenience for the nursing staff and reduce work time and the work load.
In the embodiment illustrated by FIG. 7, FIG. 8, and FIG. 9, the electronic apparatus 3 can be equipped with above mentioned light emitting component (fig not shown), the electronic apparatus 3 can automatically activate the light emitting component for ambient light compensation to improve the success rate of message recognition by the camera component 322 when the electronic apparatus 3 determines that ambient light is not sufficient for the camera component 322 to focus properly.
Back to FIG. 3A, after step S32, if the microprocessor component 33 determines the external message 51 contains the MAC Address 61 of the external device 4 then the microprocessor component 33 will determine if the Bluetooth transmitting component 34 is activated (Step S34) on the electronic apparatus 3. If the Bluetooth transmitting component 34 is not activated, the Bluetooth transmitting component 34 will be activated (step S36). However the Bluetooth transmitting component 34 can be set to be activated by default on the electronic apparatus 3, hence steps S34 and S36 may be skipped and not limited thereof.
After confirming Bluetooth transmitting component 34 is activated, the microprocessor component 33 can control the Bluetooth transmitting component 34 to establish direct Bluetooth connection via the MAC Address 61 from the external message 51 to the external device 4. More specifically, the Bluetooth transmitting component 34 establishes Bluetooth pairing protocol with the external device 4 (step S38) via the MAC Address 61 and automatically enter a PIN code C1 of the external device 4 (step S40) once Bluetooth pairing protocol is initiated. The PIN code C1 can be stored beforehand in the memory component 35 allowing electronic apparatus 3 to enter the PIN code C1 during the pairing process without manual user intervention. Once the PIN code C1 passes authentication, the electronic apparatus 3 will establish successful Bluetooth connection with the external device 4 (step S42).
After electronic apparatus 3 establishes Bluetooth connection with the external device 4, electronic apparatus 3 will request the necessary data from external device 4 (step S44). Once the electronic apparatus 3 receives the necessary data from external device 4, the electronic apparatus 3 will disconnect the Bluetooth connection with the external device 4 (step S46) and automatically deactivate the Bluetooth transmitting component 34 function (step S48) on the electronic apparatus 3. The benefit here is once the electronic apparatus 3 has completed the task it can be used again to connect to another device's MAC address to quickly establish Bluetooth connection, and steps S46 and S48 may not need to be executed, but not limited thereof.
Please refer to FIG. 3B illustrating the embodiment of the data transmission process. As described above, when the electronic apparatus 3 establishes Bluetooth connection with the external device 4 in step S42, the electronic apparatus 3 must first obtain the model code 62 of the external device 4 from the external message 51 before the electronic apparatus 3 can obtain the data from the external device 4 (step S440). The microprocessor component 33 can then determine the type of the external device 4 by the model code 62 (step S442). More specifically, the model code 62 is used to differentiate the type of the external device 4, i.e. blood pressure machine, blood glucose machine, weigh scale, or thermometer, etc. Once the electronic apparatus 3 determines the type of the external device 4, the electronic apparatus 3 will activate a corresponding communication protocol to establish connection with the external device 4 (step S444). As such, the electronic apparatus 3 uses the corresponding communication protocol that the external device 4 can understand then the necessary data can be obtained from the external device 4 (step S446).
According to the type of the external device 4, the microprocessor component 33 opens the data record sheet P1 (step S448) and fills in the obtained data into the corresponding data field (step S450). The electronic apparatus 3 will have completed the temporary storage procedure after completing step S450 and will display the data on the display screen 31 (step S452). The electronic apparatus 3 may obtain more than one data record at one time and not limited thereof.
Please refer to FIG. 4A, FIG. 4B, FIG. 4C, and FIG. 4D which illustrates the embodiment of the first to fourth embodiment of the data record sheet respectively. FIG. 4A illustrates that the electronic apparatus 3 can hold multiple data record sheets P1, e.g. body temperature, blood pressure, breath, blood sugar, blood oxygen, and body weight and height data record sheets, and these sheets can be shown on the display screen 31. FIG. 4B illustrates as the electronic apparatus 3 determines the external device 4 as a thermometer from the model code 62, the electronic apparatus 3 will open the thermometer data record sheet P1, obtains the data from the external device 4, and automatically fill in the corresponding data field of the thermometer data record sheet P1. FIG. 4C illustrates as the electronic apparatus 3 determines the external device 4 as a blood pressure machine from the model code 62, the electronic apparatus 3 will open the blood pressure data record sheet P1, obtains the data from the external device 4, and automatically fill in the corresponding data field of the blood pressure data record sheet P1. FIG. 4D illustrates as the electronic apparatus 3 determines the external device 4 as a body weight and height machine from the model code 62, the electronic apparatus 3 will open the body weight and height data record sheet P1, obtains the data from the external device 4, and automatically fill in the corresponding data field of the body weight and height data record sheet P1.
The benefit is the ability to categorize the data from different machines to avoid user confusion. For example, thermometer usually has only one value, whereas blood pressure machine has systolic, diastolic, and pulse pressure values. If all of the mentioned values are recorded on the same page, and while different data may have different units (ex. ° C. or kg), the user may enter the data in the wrong data field.
FIG. 5 illustrates an example when the external device 4 is a blood pressure machine and is used to measure the user's systolic, diastolic, and pulse pressure values. The electronic apparatus 3 will open the data record sheet P1 which is for blood pressure data and includes systolic, diastolic, and pulse pressure data fields. Once the electronic apparatus 3 obtains the mentioned data from external device 4, the microprocessor component 33 will automatically populate the corresponding data field in the data record sheet P1. This process will eliminate human intervention of data entry.
Other than the above mentioned example using the external device 4 as the blood pressure machine, FIG. 10 illustrates the sixth embodiment of external message obtainment process. This embodiment uses an electric meter as the an external device 41, the external device 41 has embedded Bluetooth transmitting component, ZigBee transmitting component, or WiFi transmitting component, etc. A RFID tag is attached to either the outer surface or placed internally of the external device 41 and the RFID tag contains the external message 53, which the external message 53 contains the MAC Address 61 of the external device 41. When an electrician needs to obtain data from the external device 41 (the electric meter), the electrician can use the electric apparatus 3 to easily retrieve the external message 53 from the external device 41 and record the data on the apparatus. The external device 41 can use barcode, text, graphic, QR code, or any other medium to record the external message 53. This embodiment uses the RFID tag as example and not limited thereof.
Please refer to FIG. 11 which illustrates the seventh embodiment of the external message obtainment. In this embodiment, a sports watch is used as an external device 42 and it has embedded Bluetooth transmitting component, ZigBee transmitting component or WiFi transmitting component, etc. A RFID tag is attached to either the outer surface or placed internally of the external device 42 and the RFID tag contains the external message 53. While the user is wearing the external device 42 and engaged in sporting activity, the external device 42 will record the activity, i.e. running distance, total calories exhausted, etc. Once the activity is completed and user wish to record the data from the external device 42, user can use the electronic apparatus 3 to read the RFID tag which contains the external message 53 by establishing a connection with the external device 42 and obtain the data record.
Lastly please refer to FIG. 12 which illustrates the eighth embodiment of the external message obtainment. In this example a treadmill is used as an external device 43 and it has embedded Bluetooth transmitting component, ZigBee transmitting component or WiFi transmitting component, etc. A RFID tag is attached to either the outer surface or placed internally of the external device 43 and the RFID tag contains the external message 53. While the user is using the external device 43, the external device 43 will record the activity, i.e. running distance, total calories exhausted, etc. Once the activity is completed and user wish to record the data from the external device 43, user can use the electronic apparatus 3 to read the RFID tag which contains the external message 53 by establishing a connection with the external device 43 and obtain the data record.
As shown by FIG. 5, the external message 51 ̃56 mainly contains the specific device MAC Address 61, specific device model code 62, and a separation symbol 63. In this embodiment, the separation symbol 63 (example from the Figure shown as **, or a space, or next line, etc.) can be used to separate the MAC Address 61 and the model code 62. More specifically, the first 12 codes (6 Bytes) of the default external message 51 ̃56 on the electronic apparatus 3 can be the MAC Address 61, or separated by separation symbol 63 so the 12 codes before or 12 codes after the separation symbol 63 determined to be the MAC Address 61, but not limited thereof. By using the separation symbol 63, the electronic apparatus 3 can determine with high efficiency whether the external message 51 ̃56 contains the MAC Address 61 of the external device 4.
Please refer to FIG. 3C, illustrating the embodiment of the data relation process. If at step S32, as shown in FIG. 3A, the electronic apparatus 3 determines that the external message 51 does not contain the MAC Address 61 of the external device 4 (e.g. the external message 51 is less than 12 codes or does not include the separation symbol 63), the electronic apparatus 3 needs to determine whether the external message 51 contains a unique ID 64 (step S50). If the external message 51 does not contain the MAC Address 61 of the external device 4 nor does it contain any unique ID 64, then the electronic apparatus 3 will not continue to process the external message 51; if the external message 51 contains the unique ID 64, then the stored data in the electronic apparatus 3 should be related to the unique ID 64 (step S52), hence the stored data should belong to the user of the unique ID 64.
For example, the unique ID 64 can represent a government issued tax ID, but not limited thereof. The electronic apparatus 3 can store one or more data simultaneously related to the unique ID 64, and these data belongs to the owner of the government issued tax ID (the unique ID 64).
Please refer to FIG. 13 illustrating the preferred embodiment of the unique ID obtainment. The electronic apparatus 3 obtains the data from the external device 4 (e.g. blood pressure machine) but it only knows the data is from the specific external device 4 but does not know which patient profile the data belongs to. Therefore the electronic apparatus 3 can proceed to obtain another external message (i.e. the external message 53 as shown in FIG. 10) to obtain the unique ID 64 from within this external message 53. The external message 53 can be stored in a RFID tag, a patient 7 can wear this tag and the unique ID 64 identifies the patient 7. When the electronic apparatus 3 obtains the unique ID 64 from the external message 53, the prior data from the external device 4 can be associated with the unique ID 64 (i.e. Systolic, diastolic, pulse pressure data) and makes association the data belongs to said patient 7.
Further, as shown in FIG. 2, the unique ID 64 can be pre-stored in the memory component 35 of the electronic apparatus 3, thus after the electronic apparatus 3 obtains the necessary data from the external device 4, the electronic apparatus 3 can provide at least one unique ID 64 for the user to choose from. When the user selects one of the unique ID 64, the electronic apparatus 3 will make an association between the obtained data and the selected unique ID 64. For example, if a nurse is caring for ten patients, the nurse can pre-record or download the unique ID 64 of the ten patients first onto the assigned electronic apparatus 3, then as the nurse uses the electronic apparatus 3 to obtain each patient's data, the data can be matched with the proper unique ID 64.
In another embodiment, the unique ID 64 can be used to identify a particular room or building, e.g. Ward room number or address, and not limited only to identify a person. For example, after the electronic apparatus 3 obtains the temperature reading from the thermometer of a ward room, the unique ID 64 of the room is obtained to make association between the ward room and the temperature reading, which will indicate the temperature reading of that particular ward room. Another example, after the electronic apparatus 3 obtains the electric meter reading of a building, the unique ID 64 of the building is obtained to make association between the building and the electric meter reading, which will indicate the electric meter usage of that particular building. The above mentioned examples only illustrates the embodiment of this invention, and not limited thereof.
Lastly refer to FIG. 3D illustrating the embodiment of the data uploading process. After the electronic apparatus 3 obtains the data, it will temporarily store the data within the memory component 35 in electronic apparatus 3 then upload the data to a backend server on a periodic basis via internet or intranet (step S60). The electronic apparatus 3 will determine if the uploading is successful (step S62), if uploading was not successful, the data will still reside in the electronic apparatus 3 and will await for the next upload process; if the upload was successful, the electronic apparatus 3 will remove the temporarily stored data (step S64) to free up the memory component 35 within the electronic apparatus 3.
In the embodiment of this invention, the electronic apparatus 3 has the application program A1 installed within, the application program A1 has the executing program code for the electronic apparatus 3, thus once the electronic apparatus 3 loads the application program A1 and executes it, the electronic apparatus 3 can proceed with the above mentioned wireless obtainment of external data, automatically establish Bluetooth connectivity with the external device 4, and request for the necessary data from the external device 4. The following describes the steps involved for the electronic apparatus 3 in wireless obtainment of external data:
a) reading the external message 51 in non-physical contact manner; b) retrieving the MAC Address 61 of the external device 4 from the external message 51; c) proceeding automatically with Bluetooth pairing with the external device 4 and establishing Bluetooth connection via the MAC Address 61; d) retrieving the model code 62 of the external device 4 from the external message 51; e) determining the type of the external device 4 according to the model code 62; f) activating the corresponding communication protocol according to the type of the external device 4; g) requesting for the necessary data from the external device 4; h) opening the data record sheet P1 in accordance to the model code 62; and i) filling in the necessary data obtained from the external device 4 into the corresponding data fields in the opened data record sheet P1.
Hence the user is only required to press the control button 36 or the touch screen on the electronic apparatus 3 to initiate the non-contact data obtaining component 32 to obtain the external message 51, the electronic apparatus 3 can automatically complete the following actions: search for the external device 4, establish Bluetooth connection with the external device 4, obtain the necessary data from the external device 4 and fill in the data into the appropriate data record sheet P1 in the electronic apparatus 3.
