## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an alert system with a sensor to detect article made of metal or magnetic and then sends the detected result to the micro-processor or the control panel to make comparison between the detected result and database. When any dangerous article made of metal or magnetic touching against the sensor, the micro-processor sends out a signal to the control panel, prompting the warning system to warn the user with signals or sounds. Meanwhile, the control panel also starts up the protection device to protect the user from being hurt by dangerous article made of metal or magnetic.
2. Description of the Prior Art
Today's medical operation still uses traditional operating tools; however, the operating knife is too sharp and the gloves too thin that make doctors fail to find any fracture or damage in the tools. Therefore, the doctors might touch the patients' blood directly because of a single hole pierced by the metal, leading to bacterial infection or disease infection and thus threatening the doctors' and the nursing staff's life.
Furthermore, cleaners cleaning up the garbage may not know the existence of dangerous article that might hurt people, such as needle head, sharp article made of metal or magnetic.
In view of such disadvantages, the inventor of the present invention was devoted to finding a solution and accomplished structural improvement for alert system.
SUMMARY OF THE INVENTION
The main objective for the present invention is to provide an alert system with a sensor called CCD able to detect article made of metal or magnetic and sends the detected result to the micro-processor, where the detected result is compared with the data in the database. If the detected result indicates the existence of article made of metal or magnetic, the micro-processor then sends out a signal to the control panel, where the warning device warns the user with sounds or signals and the protection device protects the user from being hurt.
Another objective for the present invention is to provide an alert system whose sensor can be a magnetic wave sensor that uses magnetic wave to detect article made of metal or magnetic and then sends out signals to the control panel. The control panel that detects the existence of article made of metal or magnetic sends out a signal to the warning device which warns the user with sounds or signals and protects the user from being hurt by dangerous article made of metal or magnetic.
Still another objective for the present invention is to provide an alert system whose sensor can be a thermal sensor or CCD that utilizes a thermal sensing device to detect the temperature and sends the detected results to the micro-processor. This micro-processor that receives the information from the thermal sensor and the CCD image device compares the result with the database to judge the existence of article made of metal or magnetic. If any article made of metal or magnetic is detected, the micro-processor sends out a signal the control panel, where the warning device warns the user with sounds or signals and the protection device protects the user from being hurt.
One another objective for the present invention is to provide an alert system whose sensor can be made of conductive material. When any article made of metal or magnetic touches against the conductive material, the sensor sends out a signal to the control panel where the warning device warns the user with sounds or signals. The protection device can be an airtight chamber or contains identifiable or medicinal liquid.
Still one another objective for the present invention is to provide an alert system whose sensor can be a thermal sensor or CCD that utilizes a thermal sensing device to detect the temperature of the article made of metal or magnetic. The detected results and the image information obtained by the CCD image device are converted into signals which are then delivered to the micro-processor. The micro-processor compares the image information with the database to judge the existence of article made of metal or magnetic by data of the pre-determined shape of the article made of metal or magnetic. The micro-processor that detects any article made of metal or magnetic sends out a signal to the warning device and the motor, where the warning device warns the user with sounds or signals and the motor enables the protection device to protect the user.
One more objective for the present invention is to provide an alert system whose sensor can be a diode or beeper. When the micro-processor sends out a signal to the warning device, the diode or beeper of the warning device warns the user against the article made of metal or magnetic nearby by glittering or beeping.

a control panel 3 that consists of an electronic circuit 31, a warning device 32 and a protection device 33. The control panel receives the signal from the sensor 1 to warn the user;
when article made of metal or magnetic 8 touches against the conductive material 11 of the sensor 1, putting through the electronic circuit 31 of the control panel 3, the warning device 32 is prompted to warns the user with sounds or signals. Meanwhile, the protection device 33 of the control panel 3 protects the user from being hurt by the article made of metal or magnetic. The protection device 33 could be an airtight chamber 331 (such as gas with certain smell or color) or combined with a motor 332 for pressurization. With the protection device 33 is filled with certain liquid 333 (such as colored liquid, colloid liquid) or medicinal liquid 334 the electronic circuit 31 of control panel 3 being put through starts the motor 332, pushing the liquid 333 or the medicinal liquid 334 out of the protection device 33, enabling the user to identify the liquid, and thus protect the user from being hurt. The medicinal liquid 334 could provide disinfection function when the user is wounded. The warning device 32 of the control panel 3 could be a diode 321 or a beeper 322.
In the case where the sensor 1 is a pressure sensor 13, any article made of metal or magnetic 8 that touches against the pressure sensor 13 would cause unusual pressure. Therefore, the sensor 1 sends out a signal to the electronic circuit 31 of the control panel 3 and prompts the warning device 32 to warn the user with sounds or signals. The protection device 33 of the control panel 3 consists of an airtight chamber 331 and a motor 332.
