[0010] Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments. In addition, to clarify the description, the following description and the drawings are simplified as appropriate.

[0011] First Embodiment <Notification System> The notification system according to the first embodiment will be described with reference to FIGS. 1 to 4. FIG. 1 is a perspective view showing the notification system according to the first embodiment. FIG. 2 is an exploded perspective view showing the notification system according to the first embodiment. FIG. 3 is a perspective view showing the holder according to the first embodiment. FIG. 4 is a block diagram showing the control configuration of the notification system according to the first embodiment.

[0012] It should be naturally understood that the right-handed XYZ coordinates shown in Fig. 1 and other drawings are provided for convenience in describing the positional relationship of components. Normally, the positive direction of the Z axis is vertically upward, the XY plane is a horizontal plane, and this definition is common among all the drawings. Normally, the positive direction of the X axis is forward, and the positive direction of the Y axis is leftward.

[0013] (Hardware Configuration) As shown in Fig. 1 and Fig. 2, the notification system 100 includes a radio device 10 and a holder 30. The holder 30 is capable of holding the radio device 10.

[0014] The holder 30 is a casing with an open top, and includes a bottom portion 33 and wall portions 31, 32, 34, 35. The wall portions 31, 32, 34, 35 are arranged along the outer edge of the bottom portion 33 and rise upward from the bottom portion 33. A holding portion 30A is a space surrounded by the wall portions 31, 32, 34, 35 and the bottom portion 33. The holding portion 30A has a size and shape capable of holding the radio device 10. The holder 30 may preferably include a tough case. The holder 30 may preferably be made of, for example, polycarbonate, wood, aluminum alloy, or the like. When the holder 30 holds the radio device 10, the wall portion 31 faces a keypad 12.

[0015] As shown in Fig. 3, the wall portion 31 includes an upper end portion 31A and an inner wall surface 31B. The wall portion 31 may preferably further include, for example, protrusions 31C, 31D, 31E. The protrusions 31C, 31D, 31E protrude from the inner wall surface 31B toward the holding portion 30A side. The protrusions 31C, 31D, 31E are arranged on the inner wall surface 31B so as to be capable of pressing any one of second keys 12C to 12N described later. In the present embodiment, the protrusions 31C, 31D, 31E are respectively arranged on the inner wall surface 31B so as to be capable of pressing second keys 12C, 12G, and 12E described later. The positions of the protrusions 31C to 31E on the inner wall surface 31B may be changed as appropriate.

[0016] The radio 10 comprises a main unit 11, a keypad 12, a belt clip 13, and an emergency button 14. The radio 10 also includes a microphone (not shown) and a speaker.

[0017] The main body 11 has a front surface 11A, a rear surface 11B, and a top surface 11C. The shape of the main body 11 is not particularly limited, but for example, it is a roughly rectangular parallelepiped. The main body 11 is equipped with the control device 20 shown in Figure 4.

[0018] The keypad 12 is preferably located on the front surface 11A of the main body 11. The keypad 12 comprises first keys 12A and 12B, and second keys 12C, 12D, 12E, 12F, 12G, 12H, 12I, 12J, 12K, 12L, 12M, and 12N. When the holder 30 holds the radio 10, the first keys 12A and 12B face or contact the upper end 31A of the wall portion 31. In this embodiment, the second keys 12C to 12N are arranged in 4 rows and 3 columns on the front surface 11A. The second keys 12C to 12E, the second keys 12F to 12H, the second keys 12I to 12K, and the second keys 12L to 12N are each arranged in parallel in the left-right direction (here, in the X-axis direction). At least two of the second keys 12C to 12N are positioned below the first keys 12A and 12B at different locations in the vertical direction (in this case, the Z-axis direction) and the horizontal direction. For example, the second key 12G is positioned below the second keys 12C and 12E in the vertical direction. The second key 12G is positioned between the second key 12C and the second key 12E in the horizontal direction.

[0019] The belt clip 13 is preferably positioned on the back surface 11B of the main body 11. The belt clip 13 can hold the user's belongings, such as a belt. By the belt clip 13 holding the user's belongings, the radio 10 and holder 30 are attached to the user's body. One end of the belt clip 13 is preferably rotatably connected to the back surface 11B via a torsion spring. The other end of the belt clip 13 is preferably provided so as to be able to contact or separate from the back surface 11B.

[0020] The emergency button 14 is not particularly limited, but for example, it is located on the top surface 11C of the main unit 11. When the radio 10 detects that the emergency button 14 has been pressed, it transmits emergency information indicating that an emergency has occurred. In most cases, the emergency button 14 is smaller and more difficult to press than the first keys 12A and 12B and the second keys 12C to 12N of the keypad 12. The user can press the emergency button 14 with their fingertips.

[0021] (Control configuration) As shown in Figure 4, the control device 20 includes a key detection unit 21, a man-down detection unit 22, and an emergency notification unit 23.

[0022] The control device 20 may, as a hardware configuration, include, for example, an arithmetic circuit having a CPU (Central Processing Unit) and a storage device having program memory, data memory, and other RAM (Random Access Memory) or ROM (Read Only Memory). The control device 20 acquires data and performs calculations on various data using the arithmetic circuit according to the program stored in the storage device. The control device 20 further includes a transmitting and receiving circuit capable of sending and receiving various information. Furthermore, the control device 20 may have functions to control sound pickup by the microphone of the radio 10 and audio output from the speaker of the radio 10.

[0023] The key detection unit 21 detects whether or not each key included in the keypad 12 is pressed. Specifically, the key detection unit 21 can detect when the first keys 12A and 12B are pressed approximately simultaneously. The key detection unit 21 can also detect when none of the first keys 12A and 12B are pressed, and at least two of the second keys 12C to 12N are pressed. These at least two of the second keys 12C to 12N may be positioned below the first keys 12A and 12B at different positions in the vertical and horizontal directions. Here, the pressing of the first and second keys is detected separately, but this is not particularly limited. For example, it may be possible to detect when at least one of the first keys and at least one of the second keys are pressed approximately simultaneously.

[0024] The man-down detection unit 22 detects when a user falls. The user is wearing a holder 30 that holds the radio 10. For example, the man-down detection unit 22 uses a motion sensor to continuously detect the angle of the radio 10, particularly the main unit 11. The man-down detection unit 22 also detects that the user has fallen if, for example, the detected angle of the main unit 11 exceeds a predetermined value.

[0025] The emergency notification unit 23 transmits emergency information to the other party's radio based on the detection result of the key detection unit 21 and the detection result of the man-down detection unit 22.

[0026] Specifically, the emergency notification unit 23 transmits first emergency information when the key detection unit 21 detects that at least two of the first keys 12A, 12B and the second keys 12C to 12N are pressed approximately simultaneously. The emergency notification unit 23 may also transmit first emergency information when the key detection unit 21 detects that at least two of the second keys 12C to 12N, which are located below the first keys 12A, 12B at different positions in the vertical and horizontal directions, are pressed approximately simultaneously. The first emergency information may include information indicating that the user intentionally uttered the information while conscious.

[0027] Furthermore, the man-down detection unit 22 may detect that the user has fallen. Additionally, the key detection unit 21 may detect that neither the first key 12A nor the first key 12B is pressed, and that at least two of the second keys 12C to 12N are pressed at different times, i.e., at least two different times. In such cases, the emergency notification unit 23 transmits second emergency information. The second emergency information may include information indicating at least two of the multiple second keys 12C to 12N detected by the key detection unit 21. The second emergency information may also include information indicating the order in which at least two of the second keys 12C to 12N detected by the key detection unit 21 were pressed.

[0028] The radio equipment to which the first and second emergency information is transmitted is not particularly limited. The receiving radio equipment may be, for example, a radio equipment capable of receiving on a frequency and communication method designated for emergency calls, one or more pre-configured radio equipment, the radio equipment that last communicated with radio equipment 10, the radio equipment that communicates most frequently, a radio equipment in the same group as radio equipment 10, or a base station.

[0029] (Control method) Next, the control method of the notification system 100 will be described with reference to Figure 5. Figure 5 is a flowchart showing the control method of the notification system according to Embodiment 1.

[0030] The key detection unit 21 detects whether at least two of the first keys 12A, 12B and the second keys 12C to 12N are pressed approximately simultaneously (step ST1). These at least two of the second keys 12C to 12N are preferably positioned below the first keys 12A, 12B at different positions in the vertical direction (in this case, the Z-axis direction) and the horizontal direction (in this case, the X-axis direction).

[0031] If the key detection unit 21 detects that at least two of the first keys 12A, 12B and the second keys 12C to 12N are pressed approximately simultaneously (step ST1: YES), the emergency notification unit 23 transmits the first emergency information (step ST31).

[0032] On the other hand, if the key detection unit 21 does not detect that at least two of the first keys 12A, 12B and the second keys 12C to 12N were pressed approximately simultaneously (step ST1: NO), the man-down detection unit 22 detects whether or not the user has fallen (step ST21).

[0033] If the man-down detection unit 22 detects that the user has fallen (step ST21: YES), the key detection unit 21 detects whether or not at least two of the second keys 12C to 12N have been pressed (step ST22). These at least two of the second keys 12C to 12N are preferably positioned below the first keys 12A and 12B at different positions in the vertical direction (in this case, the Z-axis direction) and the horizontal direction (in this case, the X-axis direction).

[0034] Furthermore, if the key detection unit 21 detects that at least two of the second keys 12C to 12N have been pressed (step ST22: YES), the emergency notification unit 23 transmits the second emergency information (step ST32).

[0035] If the man-down detection unit 22 does not detect that the user has fallen (step ST21: NO), the process returns to step ST1. Similarly, if the key detection unit 21 does not detect that at least two of the second keys 12C to 12N have been pressed (step ST22: NO), the process returns to step ST1.

[0036] Based on the above, the first or second emergency information can be transmitted depending on the circumstances.

[0037] In one example of the control method for the notification system 100 described above, for example, the user does not need to press the emergency button 14 shown in Figure 1 with their finger, but instead presses the holder 30 against it. As a result, the key detection unit 21 detects that at least two of the first keys 12A, 12B and the second keys 12C to 12N have been pressed approximately simultaneously, and the emergency notification unit 23 transmits the first emergency information (step ST1: YES, ST31). Therefore, the user can transmit the first emergency information even if their hands or fingers are unusable. In other words, the risk of being unable to make an emergency call can be suppressed.

[0038] Furthermore, since the first emergency information includes information indicating that the user intentionally issued it while conscious, it can be inferred that the recipient of the first emergency information is a conscious user. In this way, it can be inferred that the recipient of the first emergency information is a conscious user, so for example, when rushing to the scene, it becomes possible to gauge the user's response through proactive calls and lead to a swift rescue. Also, for example, it becomes possible to attempt to communicate with the user by remotely operating the radio 10 of the notification system 100 that transmitted the first emergency information, and alternating between calling out and picking up ambient sounds with the microphone. More specifically, first, the radio 10 of the notification system 100 transmits the first emergency information via the emergency notification unit 23 of the control device 20. Subsequently, the radio 10 of the notification system 100 receives a signal from the device that became the recipient of the first emergency information, which remotely operates the radio 10 of the notification system 100 that transmitted the first emergency information, and alternates between calling out and picking up ambient sounds with the microphone. Upon receiving this signal, the control device 20 controls the microphone and speaker of the radio 10 to alternately output a call from the speaker and pick up ambient sounds with the microphone and transmit them to the destination, thereby attempting to communicate with the user.

[0039] Furthermore, in one example of the control method for the notification system 100 described above, for example, a user falls and pushes the wall portion 31 of the holder 30 with their hand or finger. As a result, the man-down detection unit 22 detects that the user has fallen, and the key detection unit 21 detects that at least two of the second keys 12C to 12N have been pressed. In addition, the emergency notification unit 23 transmits the second emergency information. The second emergency information can be transmitted even if the user has fallen (steps ST2: NO, ST21: NO, ST22: NO, ST32).

[0040] Furthermore, the second emergency information is transmitted after the man-down detection unit 22 detects that the user has fallen. The second emergency information also includes information indicating at least two of the multiple second keys 12C to 12N detected by the key detection unit 21. The second emergency information may also include information indicating the order in which the multiple second keys 12C to 12N detected by the key detection unit 21 were pressed. Based on this, it can be inferred that the recipient of the second emergency information is in a state where the user has fallen. In this way, it can also be inferred that the recipient of the second emergency information is the user who has encountered some kind of accident, disaster, or incident. For example, it becomes possible to attempt to pinpoint the location of the radio 10 of the notification system 100 that transmitted the second emergency information with higher accuracy, leading to a quicker rescue. Furthermore, the transmission of the second emergency information makes it possible to arrange for many people to be dispatched to the rescue. Furthermore, since it can be inferred that the user may have encountered some kind of accident, disaster, or incident, it becomes possible to attempt further situation confirmation by, for example, remotely operating the radio 10 of the notification system 100 that transmitted the second emergency information, and only picking up ambient sounds with the microphone without making a call. More specifically, first, the radio 10 of the notification system 100 transmits the second emergency information via the emergency notification unit 23 of the control device 20. Subsequently, the radio 10 of the notification system 100 receives a signal from the device that received the second emergency information, instructing it to remotely operate the radio 10 of the notification system 100 that transmitted the second emergency information, and to only pick up ambient sounds with the microphone without making a call. Upon receiving this signal, the control device 20 can attempt further situation confirmation by controlling the microphone of the radio 10 to pick up ambient sounds with the microphone and transmit them to the recipient. Furthermore, the information in the second emergency information, which indicates the sequence in which multiple second keys 12C to 12N were pressed, allows for inferences about how the user fell and what their condition is, which can be used as a basis for making decisions when providing rescue.

[0041] Furthermore, the protrusions 31C, 31D, and 31E of the holder 30 are positioned on the inner wall surface 31B so that they can press any of the second keys 12C to 12N, which will be described later. Therefore, the destination for the second emergency information can be identified by the holder 30 from one of the multiple second keys 12C to 12N detected by the key detection unit 21 and the protrusions 31C, 31D, and 31E. In addition, the destination for the second emergency information can be identified by the identified holder 30 and the radio 10 held by the identified holder 30. If multiple holders 30 with different positions of protrusions 31C to 31E are used, it is advisable to pre-record the positions of the protrusions 31C to 31E of each holder 30, or the combinations of the second keys 12C to 12N corresponding to each protrusion 31C to 31E and each radio 10. This allows for the identification of the pair of holder 30 and radio 10.

[0042] <Specific example of processing> Next, with reference to Figures 6 to 8, specific examples of the processing steps ST1 and other steps of the notification system 100 shown in Figure 1 will be described. Figures 6 and 7 are schematic diagrams showing the control method of the notification system according to Embodiment 1. Figure 8 is a cross-sectional perspective view of the notification system at the cutting line VIII-VIII. Note that the wall portion 32 shown in Figure 8 is different from the wall portion 32 shown in Figure 1 in that it is being pressed.

[0043] The user wears a holder 30 that holds the radio 10 on their body. The user can press the radio 10 and holder 30 against the ground GR without using their hands or fingers, for example, by pressing their body against the ground GR.

[0044] In the example shown in Figure 6, the front surface 11A of the radio 10 is placed opposite the ground GR, and then a force F1 is applied to the holder 30, pressing the holder 30 against the ground GR. As a result, the upper end 31A of the wall portion 31 approaches the front surface 11A of the main body 11 of the radio 10, pressing at least two of the first keys 12A, 12B and the second keys 12C to 12N. The key detection unit 21 detects that at least two of the first keys 12A, 12B and the second keys 12C to 12N have been pressed approximately simultaneously (step ST1: YES). In step ST31, the emergency notification unit 23 transmits the first emergency information.

[0045] In the example shown in Figure 7, the back of the radio 10 (11B) is placed opposite the ground (GR), and then a force F2 is applied to the holder (30), pressing the holder (30) against the ground (GR). This causes the upper end (31A) of the wall portion (31) to approach the front (11A) of the main body (11) of the radio 10, pressing at least two of the first keys (12A, 12B) and the second keys (12C-12N). The key detection unit (21) detects that at least two of the first keys (12A, 12B) and the second keys (12C-12N) have been pressed approximately simultaneously (Step ST1: YES). In Step ST31, the emergency notification unit (23) transmits the first emergency information.

[0046] In the example shown in Figures 6 and 7, the user does not need to press the emergency button 14 shown in Figure 1 with their finger; they can transmit the first emergency information simply by pressing the holder 30 against the ground GR. Therefore, the user can transmit the first emergency information even if their hands or fingers are unusable. In other words, the risk of being unable to make an emergency call can be reduced.

[0047] In the example shown in Figures 6 and 7, the holder 30 is pressed against the ground GR, but the holder 30 may also be pressed against a place or object other than the ground GR. Such a place or object other than the ground GR can be anything that can generate a reaction force against the pressing force.

[0048] Furthermore, another example of each specific example of the processing by the notification system 100, such as step ST1, will be described. The key detection unit 21 does not detect that the first keys 12A, 12B and at least two of the second keys 12C to 12N are pressed approximately simultaneously (step ST1: NO), and the man-down detection unit 22 detects that the user has fallen (step ST21: YES). The wall portion 32 of the radio 10 is pressed. Then, as shown in Figure 8, the protrusions 31C, 31D, and 31E of the wall portion 31 approach the front surface 11A of the main body 11 of the radio 10, respectively, and press the second keys 12C, 12G, and 12E. The key detection unit 21 detects that at least two of the second keys 12C to 12N have been pressed, since the second keys 12C, 12G, and 12E have been pressed (step ST22: YES). In step ST32, the emergency notification unit 23 transmits the second emergency information. The second emergency information includes information indicating the second keys 12C, 12G, and 12E detected by the key detection unit 21. The destination for transmitting the second emergency information can be identified from the second keys 12C, 12G, and 12E detected by the key detection unit 21, such as the holder 30 or the radio 10.

[0049] (A modified version of the holder) The first to third modified versions of the holder 30 shown in Figure 3 will now be described. Figures 9 to 11 are top views showing the main parts of the first to third modified versions of the holder, respectively.

[0050] The holder 40 shown in Figure 9 is a first modification of the holder 30 shown in Figure 3. The holder 40 differs from the holder 30 except that it is equipped with projections 41C to 41E. The projections 41C to 41E of the holder 40 protrude from the inner wall surface 31B of the wall portion 31 toward the holding portion 30A. The projections 41C, 41E, and 41D are in that order of increasing height. The height of projection 41C is the same as the distance from the inner wall surface 31B to the tip of projection 41C. The same applies to projections 41D and 41E. The tips of projection 41C and projection 41E have a tapered shape. The tapered shape of the tip of projection 41C is inclined toward projection 41D from the base side of projection 41C toward the tip. Similarly, the tapered shape of the tip of projection 41E is inclined toward projection 41D from the base side of projection 41C toward the tip.

[0051] With this configuration of the holder 40, when a user pushes from the center of the wall 31 towards the wall 34, the difference in the distance that the protrusions 41C to 41E push into the second keys 12C, 12G, and 12E is small. This makes it possible to equalize the force applied to the second keys 12C, 12G, and 12E. The holder 40 is suitable when the user frequently pushes from the center of the wall 31 towards the wall 34.

[0052] The holder 50 shown in Figure 10 is a second modification of the holder 30 shown in Figure 3. The holder 50 differs from the holder 30 except that it has protrusions 51C to 51E. The protrusions 51C to 51E of the holder 50 have the same configuration as the protrusions 41C to 41E shown in Figure 9, except for their height. The protrusions 51E, 51C, and 51D are taller in that order.

[0053] With this configuration of the holder 50, when a user pushes from the center of the wall 31 towards the wall 35, the difference in the distance that the protrusions 51C to 51E push into the second keys 12C, 12G, and 12E is small. This makes it possible to equalize the force applied to the second keys 12C, 12G, and 12E. The holder 40 is suitable when the user frequently pushes from the center of the wall 31 towards the wall 35.

[0054] The holder 60 shown in Figure 11 is a third modification of the holder 30 shown in Figure 3. The holder 60 differs from the holder 30 except that it has projections 61C to 61E. The projections 61C to 61E of the holder 60 have the same configuration as the projections 41C to 41E shown in Figure 9, except for their height. Projection 61D is taller than projections 61C and 61E. The heights of projection 61C and projection 61E are approximately the same.

[0055] With this configuration of the holder 60, when a user presses near wall 34 or wall 35 on wall 31, the difference in the distance that projections 61C to 61E press into the second keys 12C, 12G, and 12E is small. This makes it possible to equalize the force applied to the second keys 12C, 12G, and 12E. The holder 60 is suitable when the user frequently presses near wall 34 or wall 35 on wall 31.

[0056] Based on the above, by using the first to third modified versions of the holder 30 according to various users, the force applied to the second keys 12C, 12G, and 12E can be made uniform.

[0057] It should be noted that the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. Furthermore, the present invention may be implemented by combining the above embodiments or examples thereof as appropriate. [Explanation of Symbols]
