    摘要： Biocompatible materials are propelled at the skin with sufficient velocity to cause desired resurfacing of tissue to the desired penetration depth. The materials, such as dry ice or water ice, are harmonious with the human body and thus eliminate foreign body reactions. Various materials may be used in combination, including local anesthetics and vasoconstrictors in solid or liquid form. The biocompatible solid or liquid particles are suspended in a cold carrier fluid and propelled through an insulated delivery system to the surface of the skin. The treatment of diseased skin lesions may be accomplished using the present invention as a drug delivery system.

    摘要： A device is described that can be easily used by surgeons to measure and monitor changes before, during, and after a liposuction procedure and assist in producing symmetrical body contours. The device comprises a remote control and data processing unit, a handheld ultrasound transducer, a display monitor and means for marking anatomical points to be measured.

    摘要： Tissue resurfacing is accomplished by propelling biocompatible, non-toxic materials at the tissue with sufficient velocity to cause destruction or loosening of tissues to a desired depth. The biocompatible materials are generated by abrading a solid frozen unit and propelling the abraded material onto the surface of the skin or tissue to be treated. A vacuum line near the delivery tip may used to remove excess materials or reaction by-products that build up on the surface of the skin. The treatment system generally consists of a control unit, a handheld particle generator and a cable that connects the control unit to the particle generator. The control unit can include user controls to select particle temperature, particle flux, particle velocity and vacuum. The handheld particle generator contains a mechanism to push the frozen biocompatible material against a rotating grinding wheel that produces small particles, which are propelled against tissue being treated.

    摘要： Optical breakdown by predetermined laser pulses in transparent dielectrics produces an ionized region of dense plasma confined within the bulk of the material. Such an ionized region is responsible for broadband radiation that accompanies a desired breakdown process. Spectroscopic monitoring of the accompanying light in real-time is utilized to ascertain the morphology of the radiated interaction volume. Such a method and apparatus as presented herein, provides commercial realization of rapid prototyping of optoelectronic devices, optical three-dimensional data storage devices, and waveguide writing.

    摘要： A system for detecting pressure, acoustic or ultrasound waves within an entity having a surface including the steps of attaching a signal converting material to the surface. The waves are generated by direct ejection from the surface, generation via energy deposition on the surface, generated spontaneously or, generated by directing light energy to the light absorbing target. The absorbing target subsequently generates acoustic pressure waves. The acoustic waves propagate to the surface of the entity and the signal converting material, wherein the acoustic pressure waves create vibrations in the signal converting material; and detecting the waves in the signal converting material with an optical detection system. Information about the absorbing target is obtained by the absorbing target reflecting the waves. The signal converting material can be a gel-like material containing optical elements, a multi-layer patch, or other material.
