## Background
FIELD OF THE INVENTION 
The present invention relates generally to a safety system, and particularly to a safety system for use in vehicles.
DESCRIPTION OF THE RELATED ART 
In modern society, automobiles are more and more popular as important transportation tools. However, traffic accidents are increasing along with the booming development of automobiles. In addition to human factors such as drink driving or high speed driving, main reasons for traffic accidents are generally associated with objective factors including, poor visibility, and blind zones in normal field of vision.
A typical safety device for an automobile includes a number of signal transmitters and receivers mounted in the automobile. When the automobiles equipped with the safety devices meet each other, they can transmit and receive signals to and from each other so as to inform drivers to avoid a traffic accident.
Another typical safety device for an automobile includes a laser transmitting and receiving system, a speed sensor, and a central processing unit (CPU). The safety device can inform the driver of information such as distance between other ambient automobiles or barriersby audio or video means.
Another conventional safety device includes a miniature camera configured for monitoring a blind zone of the driver and showing the images to the driver via a display screen.
However, when a fatal traffic accident happens, the driver might be injured seriously such that the driver cannot ask for help by himself/herself. For this reason, many drivers lost their lives in traffic accidents because of not being saved in time.
Therefore, a vehicle safety system can automatically send signals for help and a vehicle having such safety system are desired.

DETAILED DESCRIPTION 
Referring to FIG. 1, a vehicle and a vehicle safety system according to a preferred embodiment are illustrated. The vehicle 100 having a main body 101 and a vehicle safety system 102 mounted thereon. The vehicle can be a typical passenger automobile with a driver's seat 180 and five passenger seats 190. The vehicle safety system 102 includes: a number of inner image pick-up systems 10 mounted outside the vehicle 100, a number of outer image pick-up systems 20 mounted inside the vehicle 100, a monitor display 30, an air bag restraint system 40, and a computer system 50. The computer system 50 is connected to the inner and outer image pick-up systems 10 and 20, the monitor display 30, and the air bag restraint system 40. The computer system 50 comprises a storage device 51 and a signal transmitting device 52.
Referring to FIG. 2, the inner and outer image pick-up systems 10 and 20 each include an autofocus zoom lens systems 200. The autofocus zoom lens system 200 includes an optical module 210, a sensor 220, and a driving module 230. The optical module 210 includes a plurality of aspheric lens 211 and an infrared filter 212. More preferably, the aspheric lens 211 has anti-reflect coatings on both surfaces thereof. The sensor 220 can be a CMOS (complementary metal-oxide semiconductor) sensor, or a CCD (charged coupled device) sensor. The driving module 230 includes an actuator 231 and an extendable barrel 232. The actuator 231 may be selected from the group consisting of a step motor, a voice coil motor, and a microelectromechanical motor. In this exemplary embodiment, the optical module 210 includes three aspheric lenses 211. The sensor 220 is a CCD sensor. The actuator 231 is a microelectromechanical motor. It is noted that, more lenses can be used in order to get better resolution and zoom ability.
The outer image pick-up systems 10 can be arranged at front side, back side, and two lateral sides of the vehicle 100 for monitoring the environmental traffic status around the vehicle 100 via the autofocus zoom lens systems 200. The inner image pick-up systems 20 can be arranged spatially corresponding to the seats of the vehicle 100 for monitoring the status of passengers in the vehicle. Video image captured by the image pick-up systems 10 and 20 can be transferred to the computer system 50. The driver can selectively choose to view a desired video image displayed on the monitor display 30. Alternatively, more monitoring video images can be displayed on the monitor display 30 at the same time.
The computer system 50 can save the video images into the storage device 51, and send the video images to intended receivers in a form of RF (radio frequency) signals via the signal transmitting device 52. For example, the computer system 50 may be preset to send the video images to the owner of the vehicle 100, even though the vehicle 100 has been stolen. The video images can be provided to the police for aiding them in solving the case. For example, when a traffic accident happens, the CPU of the air bag restraint system 40 may send an instruction and controll a gas generator (not shown) to instantly inflate an air bag (not shown). At the same time, the computer system 50 receives the instruction and then controls the signal transmitting device 52 to send RF signals for help and video images to the intended receivers such as a hospital, a police station, a fire station etc. Even though the driver or the passengers are too seriously injured to ask for help themselves, the receivers can still get detailed information about the accident, such as the states of the injured driver or the passengers and the status of the vehicle 100 and the accident scene. Thereby, succors can take timely measures without unduly delay. Thus the property damage and physical injury can be minimized.
Furthermore, the vehicle safety system 102 includes a number of detectors 70 connected to the computer system 50. The computer system 50 further comprises an annunciator 53. The detectors 70 can be arranged at front side, back side, and two lateral sides of the vehicle 100. The detectors are configured for detecting distances between the vehicle 100 and ambient vehicles or objects, and sending the distance data to the computer system 50. When distance detected by the detectors 70 is less than a safety distance, the computer system 50 will send out sound alerts to prompt the driver via the annunciator 53. The annunciator 53 can provide prompts in various forms for example human voice prompts. So, even though the driver overlooks the video images displayed on the monitor display 30, the annunciator 53 can still prompt the driver with sound alerts. As a result, potential risks of a traffic accident can be further minimized.
The vehicle safety system has real time image pick-up systems and a signal transmitting device. This configuration helps the driver to instantly monitor the status around the vehicle anytime. Even though a mishap accident, for example, the driver unfortunately get a serious heart attack, and can't ask for help himself/herself, or otherwise for example, a traffic accident happens, and the driver or the passengers are too seriously injured to ask for help themselves, the signal transmitting device can still send signals and real time video images to intended receivers for help. In addition, the image pick-up system using optical systems with aspheric lenses have advantages such as compact and lightweight.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
