Abstract: The present invention is a portable personalized air purifier intended to be attached to the belt or to the neck of a user. Purified air is generated by filtering, electrochemically, and UV LED treating of a polluted air. Polluted air is forced through a filter into ionized water, which absorbs particles and kills possible air born bacteria. The UV LED disinfects the polluted air. The device further balances the humidity of the air and delivers healthy air towards the face of the user through a mask.

Abstract: The present invention is a portable air purifier device intended to be attached to the belt or to the neck of the user and generate purified air enough to breath easily and adequate to make an air curtain to push a way ambient air. Principle of the operation of this device is to push inlet polluted air through layers of ionized water. Water will absorb particles and copper and silver ion kills possible air born bacteria and produce clean air. The purified air will be then delivered to the face of the user either by a flexible hose to a mask or through several flexible hoses to form an air curtain in front of a user's face.

Abstract: A disinfection device for a trapped-liquid comprising of a drain trap for a liquid flow having an inner surface to trap a volume of the trapped-liquid and a helical coil capable of generating metal ions to eliminate biological cells attached to said drain trap. An electric valve is connected to a tap water and the helical coil and a power supply provides a current and a voltage to the helical coil for a period of ionization and a sensor system installed in the drain trap to sense flow of a liquid through the drain trap. A timer system to determine the length of a stagnant-time that the trapped-liquid is stagnant in the drain trap; and to determine the length of an ionization-time for the period of ionization.

Abstract: The present invention is a portable air purifier device intended to be attached to the belt or to the neck of a user. Purified air is generated by electrochemically and magnetically treating a polluted air. Polluted air is forced through an ionized water, which absorbs particles and kills possible air born bacteria. A magnetic filter assures that small metal particles are also separated from the polluted air. The purified air is then delivered towards the face of the user either through an air curtain or through a mask.

Abstract: The present invention is a portable hand-held battery-operated therapeutic ultrasonic device that is specifically designed for clinical applications in muscle and joint pain management. The present invention generates stepwise high resolution, high frequency microprocessor-based signal to drive piezo-crystals for applying on the skin of the user. It makes use of a novel electronic driving technology that enables it to generate therapeutically combinations of acoustic intensities from 0 to 2 W/cm2 and with 80-85% efficiency. It is a lightweight device and can be programmed wirelessly by a physician/professional to be used at home by a patient.

Abstract: The present invention discloses an anti-cheating system in online examinations. The system includes a personalized eye recognition device comprising of a monitor and an eye recognition technology connected to a computer, on which a student may take a test. The eye recognition device has a verification module for verify the examinee according to a set of verification data. The eye-monitor would display the answers only if the glass is on the eye of the right person. The eye recognition device comprises of an optical imager that obtains the image of the user's iris, and then compares it with a previously obtained and stored image of the user's iris. The present anti-cheating examination system further comprises a video camera to collect and transmit images of the examinee to an identity recognition system, a computer device to provide questions and answer keys thereon and a microphone for voice recognition and check the background voices and control the examination environment voices.

Abstract: A siphon trap disinfection unit consisting of a copper/silver electrode coated on inside body of the siphon parallel to each other along the siphon in the area which water normally stands. A water level sensor to generate resistance between two electrodes and an electric controller circuit to generate ions by applying voltage between two electrodes and controlling the amount of current passing through this control circuit to generate enough concentration of copper and silver ion continuously in the water standing area of the siphon trap to remove and deactivate harmful bacteria's in this area.
