## Title
System and method for sending a safety monitor report using a mobile device

## Abstract

A safety monitoring system and method sets a preset acceleration and a preset gravity gradient of a mobile device, and a preset contact. If an obtained acceleration and a gravity gradient of the mobile device are greater than preset values, the system and method obtains positional data of the mobile device using a global positioning system (GPS) unit of the mobile device. The system and method further packs the positional data into short message service/multimedia message service (SMS/MMS) message, searches for the preset contact in the mobile device, and sends a safety monitor report to the preset contact by the SMS/MMS message.

Embodiments of the present disclosure relate to safety monitor management, and particularly to a system and method for sending a safety monitor report using a mobile device.
2. Description of Related Art
In our modern information-oriented society where communication systems are highly developed, compact-sized mobile phones are broadly utilized for communications between people in daily life. Mobile phones can be used to exchange information and communicate with each other almost anytime and anywhere. Currently, a mobile phone can determine a position of a user (e.g., an old person) using a global positioning system (GPS) unit. However, the current mobile phone cannot determine a safety status of the user.

DETAILED DESCRIPTION
All of the processes described below may be embodied in, and fully automated via, functional code modules executed by one or more general purpose mobile devices or processors. The code modules may be stored in any type of readable medium or other storage device. Some or all of the methods may alternatively be embodied in specialized hardware. Depending on the embodiment, the readable medium may be a hard disk drive, a compact disc, a digital video disc, or a tape drive.
FIG. 1 is a schematic diagram of one embodiment of a mobile device 5 comprising a safety monitoring system 20. The safety monitoring system 20 may be used to send a safety monitoring report to a preset contact of the mobile phone 5 if an obtained acceleration and a gravity gradient of the mobile device 5 are greater than preset values. Thus, the mobile device 5 may be used to send the safety monitor report to the preset contact with positional data of the mobile device 5, so as to inform the preset contact of a safety status of the user of the mobile device 5.
In one embodiment, the safety monitoring system 20 obtains an acceleration and a gravity gradient of the mobile device 5 using a gravity sensor (G-sensor) 40. If the acceleration and the gravity gradient are greater than preset values, the safety monitoring system 20 obtains positional data of the mobile device 5 using a global positioning system (GPS) unit 42. Then, the safety monitoring system 20 searches a preset contact from a contact list 21 stored in a storage system 2, and sends a safety monitor report including the positional data to the preset contact. In one exemplary embodiment, the G-sensor 40 and the GPS unit 42 may be included on a printed circuit board (PCB) 4 of the mobile device 5. In one embodiment, the storage system 2 includes the safety monitoring system 20 and the contact list 21.
The CPU 1 controls execution of computerized codes of the safety monitoring system 20. In one embodiment, the mobile device 5 includes a central processing unit (CPU) 1, the storage system 2, an input/output device 3, and the PCB 4. The CPU 1 is electronically connected to the storage system 2, the input/output device 3, and the PCB 4. The PCB 4 is connected to the storage system 2. The storage system 2 may be a flash memory, and the input/output device 3 may include a liquid crystal display (LCD) and a keyboard, but the disclosure is not limited thereto. In one embodiment, the mobile device 5 may be a cell phone, a digital camera, or a personal digital assistant (PDA), for example.
FIG. 2 is a block diagram of one embodiment of the safety monitoring system 20 in FIG. 1. In one embodiment, the safety monitoring system 20 includes a parameter setting module 201, a safety determining module 202, a data obtaining module 203, and a report sending module 204.
The parameter setting module 201 sets monitor parameters of the mobile device 5. In one embodiment, the monitor parameters include a preset acceleration of the mobile device 5, a preset gravity gradient of the mobile device 5, and a preset contact in the contact list 21. It is understood that, a gravity gradient is an angle between a sensitive axis of the G-sensor 40 and an acceleration of a Y-axis of the G-sensor 40 (refer to FIG. 4A and FIG. 4B). For example, in one embodiment, the preset acceleration is 6.5 meters/second^2, and the preset gravity gradient is 30 degrees.
The safety determining module 202 obtains an acceleration and a gravity gradient of the mobile device 5 using the G-sensor 40, and determines if the obtained acceleration is greater than the preset acceleration and if the obtained gravity gradient is greater than the preset gravity gradient.
If the obtained acceleration is greater than the preset acceleration and the obtained gravity gradient is greater than the preset gravity gradient, the data obtaining module 203 obtains positional data of the mobile device 5 using the GPS unit 42, and packs the positional data into short message service/multimedia message service (SMS/MMS) message.
The report sending module 204 searches for the preset contact from the contact list 21 in the mobile device 5, and sends a safety monitor report to the preset contact by the SMS/MMS message. In one embodiment, the SMS/MMS message includes the positional data of the mobile device 5.
If the obtained acceleration is less than or equal to the preset acceleration, or the obtained gravity gradient is less than or equal to the preset gravity gradient, the safety determining module 202 further obtains an acceleration and a gravity gradient of the mobile device 5 after a preset time interval.
FIG. 3 is a flowchart of one embodiment of a method for sending a safety monitor report using the mobile device 5.
In block S41, the parameter setting module 201 sets monitor parameters of the mobile device 5. In one embodiment, as mentioned above, the monitor parameters include a preset acceleration of the mobile device 5, a preset gravity gradient of the mobile device 5, and a preset contact in the contact list 21 stored in the storage system 2.
In block S42, the safety determining module 202 obtains an acceleration and a gravity gradient of the mobile device 5 using the G-sensor 40.
In block S43, the safety determining module 202 determines if the obtained acceleration is greater than the preset acceleration and if the obtained gravity gradient is greater than the preset gravity gradient. If the obtained acceleration is greater than the preset acceleration and the obtained gravity gradient is greater than the preset gravity gradient, the procedure goes to block S44. Otherwise, if the obtained acceleration is less than or equal to the preset acceleration, or the obtained gravity gradient is less than or equal to the preset gravity gradient, the procedure returns to block S42.
In block S44, the data obtaining module 203 obtains positional data of the mobile device 5 using the GPS unit 42.
In block S45, the data obtaining module 203 packs the positional data into short message service/multimedia message service (SMS/MMS) message.
In block S46, the report sending module 204 searches for the preset contact from the contact list 21 in the mobile device 5, and sends a safety monitor report to the preset contact by the SMS/MMS message. In one embodiment, the SMS/MMS message includes the positional data of the mobile device 5.
