A dermatology handpiece delivers a treatment beam of optical energy to a lesion. The handpiece has the ability to selectively determine whether or not the treatment beam is delivering optical energy to a lesion or to healthy tissue. This is achieved without visual inspection of the skin surface by the physician. Slight variations in tissue, not readily discernable by the human eye, can be detected...

The invention concerns the cementaion of an oil bore hole or of similar bore holes. According to the invention, the theoretical acoustic impedance of cement is evaluated as a function of some theoretical cementaion parameters, this impedance is corrected as a function of the actual meeasured density of the cement slag during pumping, a correlation is established between with the depth as a functio...
