Example 1
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
This embodiment exemplifies a case where the present invention is applied to a foldable (open / closed) mobile phone device as a mobile terminal device, and FIG. 1 is an external view of the mobile phone device.
In addition to a telephone call function, an e-mail function, and an Internet connection function (Web access function), the mobile phone device has a drop notification function that notifies the user when there is a high possibility that the device body has been dropped. This apparatus main body is comprised by two housing | casings, and has comprised the display part side housing | casing 1 and the operation part side housing | casing 2 via the hinge part 3 so that opening and closing was possible. In FIG. 1A, the display unit side body 1 is superimposed on the operation unit side body 2 so that the display surface 1A of the display unit side body 1 faces the operation surface 2A of the operation unit side body 2. FIG. 1B shows a state in which the display unit side body 1 is opened from the state of FIG. 1A in which the device main body is folded. .

FIG. 2 is a block diagram showing basic components of the cellular phone device.
The central control unit 11 operates by supplying power from a power supply unit 12 including a secondary battery, and controls the overall operation of the mobile phone device according to various programs in the storage unit 13. The storage unit 13 includes a ROM and a RAM. The program area stores a program for realizing the present embodiment in accordance with an operation procedure shown in FIG. 4 to be described later. Is provided with an address book AD, which will be described later. The wireless communication unit 14 takes in a signal from the reception side of a transmission / reception unit (baseband unit) connected to an antenna and demodulates the signal to a reception baseband signal, and then outputs a sound from the reception speaker 16 via the call unit 15. Then, the wireless communication unit 14 takes in the voice data input from the transmission microphone 17 from the call unit 15, encodes it into a transmission baseband signal, gives it to the transmission side of the transmission / reception unit, and causes the antenna to transmit it.

  On the other hand, display data received and acquired via the wireless communication unit 14 by the e-mail function or the Internet connection function is given to a display unit 18 such as an LCD (Liquid Crystal Display) capable of high-quality display and output. The operation unit 19 includes various operation keys, a pointing device, and the like, and performs dial input, character input, command input, and the like. The central control unit 11 performs processing according to an operation input signal from the operation unit 19. Execute. The notification unit 20 includes a speaker for notification of incoming calls, an LED (light emitting diode), and a vibration motor. The notification unit 20 is driven when a call / mail is received to notify the incoming call, and is also driven during alarm notification. The style detection sensor 21 is a magnetic sensor or a micro switch that detects an open / closed state between the display unit side body 1 and the operation unit side body 2, and the central control unit 11 determines the display unit side based on the detection signal. It is determined whether the casing 1 and the operation unit side casing 2 are in the open style or the closed style in which they are closed. A GPS (Global Positioning System) unit 22 receives and acquires a current position (longitude and latitude) using a satellite and a ground control station.

 The impact sensor 23 constitutes an acceleration sensor that detects vibration (impact) applied to the apparatus main body, and detects various states depending on the intensity of the impact. That is, when a large impact is applied, it is detected that the device body has been dropped from the strength of the impact and the regularity of the change, or the device body is left dropped with detection of no impact immediately thereafter It is detected that the main body of the apparatus is picked up by receiving a slight impact from the state of being left unattended. The body temperature sensor 24 constitutes a contact sensor (human body sensor) that detects a body temperature that is thermally conducted when a human body is in contact with the apparatus main body. It is determined whether or not the main body is held. The conductor sensor 25 constitutes a contact sensor (human body sensor) for detecting that the human body (conductor) is in contact with the apparatus main body, and the central control unit 11 is provided with the apparatus main body according to the presence or absence of contact. It is determined whether or not it is in a state.

 Based on the detection signal from the impact sensor 23, the central control unit 11 determines whether or not a predetermined impact has been received, and determines whether or not a predetermined time has elapsed since receiving the predetermined impact. It is determined whether or not there is a possibility that the main body has been left, and if there is a possibility that the main body has been left, an alarm notification process and an e-mail notification process to notify that are executed. Here, the central control unit 11 discriminates the possibility of leaving according to the detection result of the impact sensor 23. However, the central control unit 11 discriminates the detection result of the body temperature sensor 24 and the conductor sensor 25 as necessary. I am doing so.

 The optical sensor 26 includes, for example, a photoconductive cell, and detects a change in the brightness of the surrounding environment by detecting external light (natural light or artificial light). That is, it detects whether the brightness of the environment has changed from “bright” to “dark” or vice versa, and the central control unit 11 detects from the optical sensor 26. If it changes from “dark” to “light” based on the signal, there is a high possibility that the mobile phone has dropped or protruded from the user's pocket or bag, etc. Conversely, from “light” to “dark” If there is a change, it can be determined that there is a high possibility that the mobile phone is hidden under something.

FIG. 3 is a diagram for explaining the address book AD.
The address book AD stores and manages information related to each communication partner. The address book AD has items of “partner name”, “phone number”, “mail address”, and “notification destination flag”. Is information arbitrarily set by a user operation. The “notification destination flag” is used to specify a partner who is notified by e-mail when there is a high possibility that the device main body is left unattended. For example, a family mobile child device is notified by the family Specified as the destination. If a plurality of notification destinations are designated by the “notification destination flag”, the plurality of people are notified by e-mail all at once.

  Next, the operation concept of the cellular phone device in the first embodiment will be described with reference to the flowchart shown in FIG. Here, each function described in this flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This is the same in other embodiments described later. In addition to the recording medium, the program / data supplied from the outside via the transmission medium can be used to execute operations specific to this embodiment.

FIG. 4 is a flowchart showing the characteristic part of the first embodiment that is started by the impact detection by the impact sensor 23. When the flow of FIG. 4 is exited, the overall operation flow (not shown) is performed. Return.
First, the central control unit 11 periodically monitors a detection signal from the impact sensor 23 (for example, every second), and detects that an impact has been applied to the apparatus body according to the detection signal. Step 4 is started, and it is determined whether a predetermined impact has been received, that is, whether the impact strength is equal to or higher than the first level (step A1). Here, if the impact is small and less than the first level (NO in step A1), it is determined that the impact is not caused by dropping the main body of the apparatus, and the flow of FIG. If so (YES in step A1), it is further determined whether the impact is greater than or equal to the second level (step A2).

 If the impact is equal to or higher than the second level (YES in step A2), it is determined that the apparatus main body may have been dropped, and the process proceeds to step A3. The acceleration is “0” based on the detection signal from the impact sensor 23. In other words, it is checked whether or not the impact (vibration) due to the drop has disappeared, and it is in a standby state until it is stabilized (until the vibration is eliminated). In this case, the central control unit 11 determines whether or not a predetermined impact has been applied to the apparatus main body by monitoring the transition of the detection signal from the impact sensor 23 in time series. That is, after receiving the impact of the second level or higher, it is determined whether or not the impact is caused by dropping the apparatus main body based on whether or not the impact is gradually attenuated and the vibration due to the drop is eliminated.

 If the impact is greater than or equal to the first level and less than the second level (NO in step A2), the process proceeds to step A3, and whether or not the apparatus main body is gripped based on detection signals from the body temperature sensor 24 and the conductor sensor 25. Check out. That is, the central control unit 11 determines whether or not the apparatus main body is held according to the amount of change in the temperature detected by the body temperature sensor 24, and whether the apparatus main body is held according to whether or not the conductor sensor 25 is in contact. If at least one of them is determined to be held in the hand (YES in step A3), it is determined that there is no impact caused by dropping the apparatus main body, and the flow of FIG. Exit. If it is not held in the hand when it receives an impact (NO in step A3), it is determined that the main body of the apparatus may have been dropped, and the process proceeds to step A4, where it waits until there is no impact due to the drop. .

 Here, when vibration due to dropping is eliminated (YES in step A4), the speaker constituting the notification unit 20 is driven to generate a single sound with a low volume (alarm sound) (step A5), and then an addition timer ( A time measuring operation (not shown) is started (step A6). This addition timer measures the elapsed time since receiving an impact caused by dropping. After starting the addition timer, the impact sensor 23 is accessed again to check for the presence of acceleration (vibration) (step A7). . Here, when the user notices that the user himself / herself has dropped due to the alarm notification and picks it up, vibration is applied by the action, so the above-described step A7 determines whether or not the pick-up has been performed. If there is no vibration (if left unattended), it is checked whether or not a predetermined time (for example, 5 seconds) has elapsed since the impact of the drop by referring to the time measured by the addition timer (step A8). ), If the predetermined time has not elapsed, the process returns to step A7. Here, when vibration is received before 5 seconds have passed (YES in step A7), it is determined that it has been picked up, and the flow of FIG. 4 is exited.

 If no vibration is received even after 5 seconds have elapsed (YES in step A8), it is highly possible that the speaker has been dropped, so the speaker constituting the notification unit 20 is driven, and a continuous loud sound ( After generating an alarm sound (alarm sound), an alarm notification process is performed to notify that it is left unattended (step A9), and then the impact sensor 23 is accessed to check for the presence of acceleration (vibration) (step A10). When the user notices that the user has dropped by this alarm notification and picks it up, vibration is applied by the action, but if there is no vibration and it is left unattended (NO in step A10), refer to the time measured by the addition timer. Then, it is checked whether or not a predetermined time (for example, 10 seconds) has elapsed since receiving the impact due to dropping (step A11).

 If it is picked up before 10 seconds have passed since it was dropped (YES in step A10), the flow of FIG. 4 is exited. If it is not changed (YES in step A11), the address book AD is referred to, the partner to whom the “notification destination flag” is set is identified, the “mail address” is read, and the mobile phone is addressed to this mail address. A mail notification process is performed to notify that it has been dropped and left (step A12). For example, a notification is sent to the mail address of the parent that the child has left the mobile phone dropped.

 As described above, in the first embodiment, the central control unit 11 may be left depending on whether or not a predetermined time has elapsed since the impact sensor 23 detected that the predetermined impact was received. If there is a possibility of being left unattended, alarm notification processing and email notification processing to notify that are executed, so notification is performed just by hitting something as before. It is possible to avoid useless notifications and notifications and improve reliability.

  The central control unit 11 determines whether or not a predetermined impact has been applied to the main body of the apparatus by monitoring the transition of the detection signal from the impact sensor 23 in time series. It is possible to accurately distinguish between an impact and an impact caused by dropping.

  If the impact detected by the impact sensor 23 is greater than or equal to the first level and less than the second level, it is checked whether the device main body is gripped based on the detection signals of the body temperature sensor 24 and the conductor sensor 25, and the impact is detected. If it is not held in the hand when it is received, it can be determined that the apparatus main body may have been dropped.

  If there is a possibility of being left unattended, the central control unit 11 performs the alarm notification process and the mail notification process to notify that, so that the loss prevention effect is high. In this case, after executing the alarm process, the e-mail notification process is executed when a predetermined time elapses, so the e-mail notification process can be performed when the user himself / herself has not noticed that the alarm has been dropped due to the alarm notification, It will be in line with the actual situation.

In the first embodiment described above, when the impact detected by the impact sensor 23 is greater than or equal to the first level and less than the second level, the apparatus main body is based on the detection signals of the body temperature sensor 24 and the conductor sensor 25. Although it is checked whether or not it is gripped, the presence or absence of an impact may be checked by accessing the impact sensor 23 on the condition that the apparatus main body is not gripped.
(Example 2)

The second embodiment of the present invention will be described below with reference to FIG.
In the first embodiment described above, an alarm notification and e-mail notification of the possibility of neglecting are made on the condition that a predetermined time has passed since receiving a predetermined impact, but in this second embodiment, On the condition that the apparatus main body is not in use when a predetermined impact is received, an alarm notification and e-mail notification of the possibility of being left unattended are made.
Here, the same or the same names in both embodiments are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIG. 5 is a flowchart showing the characteristic part of the second embodiment that is started by the impact detection by the impact sensor 23. When the flow of FIG. 5 is exited, the overall operation flow (not shown) is performed. Return.
First, the central control unit 11 periodically monitors a detection signal from the impact sensor 23 (for example, every second), and detects that an impact has been applied to the apparatus body according to the detection signal. 5 is started, and it is determined whether the impact strength is equal to or higher than a predetermined level (step B1). Here, if the impact is small and less than a predetermined level (NO in step B1), it is determined that the impact is not caused by dropping the main body of the apparatus, and the flow of FIG. 5 is exited. If it is determined that there is a possibility that the apparatus main body has been dropped (YES in step B1), the process proceeds to step B2, and based on the detection signal of the style detection sensor 21, it is determined whether the apparatus is in the open style state. Check if is in use.

  If an impact of a predetermined level or more is received in the closed style state (NO in step B2), the possibility of an impact due to a drop is high. (Step B4), an addition timer (not shown) for measuring the elapsed time since receiving the impact due to dropping is started (Step B5). Further, when an impact of a predetermined level or more is received in the open style state (YES in step B2), for example, by determining whether a predetermined application such as a telephone call process or a mail creation process is in operation, the apparatus body It is checked whether it is in use (step B3). If the application is operating (in use), it is determined that it is not a shock due to dropping, and the flow of FIG. 5 is exited. However, even in the open style, if it is not in use (NO in step B3), Since there is a high possibility of an impact due to dropping, the above-described addition timer is started (step B5) together with an alarm notification (step B4).

  Then, it is checked whether an operation for turning off the alarm notification is performed during a predetermined time (for example, 5 seconds) after receiving the impact due to the drop (steps B6 and B7). If the operation is performed before 5 seconds elapses (YES in step B6), the flow of FIG. 5 is exited, but the alarm notification operation is not performed even after 5 seconds ( In step B7, NO), the address book AD is referred to, the partner to whom the “notification destination flag” is set is identified, the “mail address” is read, and the mobile phone is dropped to this mail address and left unattended. A mail notification process for informing this is executed (step B8).

  As described above, in the second embodiment, the central control unit 11 is left depending on whether or not the apparatus main body is in use when it is detected that the impact sensor 23 has received a predetermined impact. If there is a possibility of being left unattended, alarm notification processing and e-mail notification processing to notify that are executed. Notification is not performed just by hitting the crab, useless notification and notification can be avoided, and reliability can be improved.

  In addition to determining the use state, the central control unit 11 can determine that there is a high possibility that the apparatus main body is dropped and left when a predetermined time has elapsed since it was determined that the device is not in the use state. .

 Based on the detection signal of the style detection sensor 21, it is determined whether or not the apparatus main body is in use by determining whether or not it is in an open style state. It can be judged that there is a high possibility of impact.

  Since it is checked whether the device itself is in use by determining whether a predetermined application such as telephone call processing or mail creation processing is in operation, if an impact is received while the application is not operating It is possible to determine that there is a high possibility of impact due to falling.

In the second embodiment described above, the folding (opening and closing) type mobile phone device is exemplified. However, the slide-type mobile phone capable of sliding the display unit side case 1 and the operation unit side case 2 can be used. It may be a telephone device or a two-axis type mobile phone device capable of rotating the display unit side body 1 by 180 °.
Example 3

A third embodiment of the present invention will be described below with reference to FIG.
In the first embodiment described above, it is determined whether or not the apparatus main body has been left by the impact detection by the impact sensor 23 depending on whether or not a predetermined time has passed. In the embodiment, it is determined whether or not it is left unattended according to whether a predetermined time has elapsed after the environment has changed (the ambient brightness has changed).
Here, in the first and third embodiments, the same or the same names are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the third embodiment. It shall be.

FIG. 6 is a flow chart showing the characteristic part of the third embodiment which is started by detecting the change of the external light by the optical sensor 26. When the flow of FIG. Return to (omitted).
First, the central control unit 11 periodically monitors the detection signal from the optical sensor 26 (for example, every second), and the brightness of the environment changes from “bright” to “dark” according to the detection signal. If the phone changes or changes from “dark” to “bright”, the mobile phone is likely to fall out of the user ’s pocket or bag, protrude, or hide under something. 6 is started, and the speaker constituting the notification unit 20 is driven to generate a single sound with a low volume (alarm sound) (step C1). Then, the external light changes (the environment changes). ) Is started (step C2).

  Thus, when it is detected by a change in external light that the apparatus main body has been dropped, protruded, hidden under something, or separated from the user, the central control unit 11 detects the body temperature sensor 24 and the conductor sensor 25. Is turned on (driven) (step C3), and it is determined whether or not the apparatus main body has been picked up before a predetermined time (for example, 5 seconds) elapses after leaving the user (steps C4 and C5). That is, based on detection signals from the body temperature sensor 24 and the conductor sensor 25, it is checked whether the apparatus main body has been grasped (pick up) (step C4), and noticed that the user has dropped it by alarm notification before 5 seconds have passed. If it is picked up (YES in step C4), the flow of FIG. 6 is exited, but if it is not picked up after 5 seconds (NO in step C5), it is determined that it has been left as it is and step C6 is entered. After obtaining the current location from the GPS unit 22 as a lost place, refer to the address book AD, identify the partner for whom the “notification destination flag” is set, and read the “mail address”. Create a notification email that includes your current location (lost location) in the email that informs you that your cell phone has been dropped. It executes the mail notification process (step C7).

  As described above, in this third embodiment, the central control unit 11 determines whether or not the optical sensor 26 has been left for a predetermined time after it has been detected that the ambient brightness has changed. However, if there is a possibility of being left unattended, since alarm notification processing and email notification processing to notify that are executed, notification will not be performed just by hitting something like conventional, Unnecessary notification and notification can be avoided, and reliability can be improved.

  When a change in ambient light is detected by the optical sensor 26, it is checked whether or not the apparatus main body is gripped based on detection signals from the body temperature sensor 24 and the conductor sensor 25, and is held by the hand when a change in ambient light is detected. If not, it can be determined that there is a high possibility that the user has fallen from the pocket or bag of the user, protruded, or hidden under something.

If there is a possibility of being left unattended, the central control unit 11 performs the alarm notification process and the mail notification process to notify that, so that the loss prevention effect is high. In this case, after executing the alarm process, the e-mail notification process is executed when a predetermined time elapses, so the e-mail notification process can be performed when the user himself / herself has not noticed that the alarm has been dropped due to the alarm notification, It will be in line with the actual situation. In this case, since the mail including the current position (lost place) is created and notified, it is possible to confirm where the mail is lost.
