  • Surface and air sterilization using ultraviolet light and ultrasonic waves
    Patent number: 6576188
    Abstract: A method and apparatus for sterilizing organic or inorganic matter through simultaneous exposure to ultraviolet light energy and ultrasonic wave energy in a non-aqueous environment such as air. The method is suitable for use in a chamber or in a mass production assembly line setting. Purification of air is similarly accomplished using simultaneous exposure to ultraviolet light and ultrasonic energy waves.

  • Sterilization using ultraviolet light and ultrasonic waves
    Patent number: 6090346
    Abstract: A sterilization method for organic or inorganic matter which combines exposure to ultraviolet light and ultrasonic waves. The ultrasound waves are applied "dry" in that the object is not immersed into a liquid solution during the exposure cycle. This makes the sterilization method suitable for use in a mass production assembly line setting. Exposure of the object to the ultraviolet light and ultrasound waves can occur simultaneously, sequentially, or in alternating fashion.
