摘要： A skin proximity sensor and method are disclosed in a dermatologic treatment device that includes a bezel or similar surface, and a treatment source capable of being activated to supply a dermatologic treatment through the bezel or surface, such as a window or similar port. A plurality of contacts leading to remotely located capacitors, in some embodiments, or a plurality of capacitive sensors in other embodiments, is positioned in or under the bezel and around the window, and control circuitry coupled to the plurality of capacitors senses the change in capacitance due to skin and inhibits activation of the dermatologic treatment device unless the proximity of skin is sensed. The presence of skin is detected, for example, by measuring changes in charge and discharge times, indicating a variation in capacitance.

摘要： An acne treatment system, device and method includes optical visualization means for identifying areas of skin colonized by the P. acnes bacteria, and further comprises methods, techniques and apparatus for the reduction or elimination of such colonies through the use of light of a power density and wavelength configured to be absorbed by porphyrins produced by the bacteria, resulting in a quenching. Various alternative embodiments are disclosed, including eye safe embodiments, embodiments in which a treatment regimen is provided on a disposable cartridge, embodiments in which the authenticity of the cartridge is verified to ensure proper operation, as well as others.
