Abstract: A device for skin treatment includes an LED (light-emitting diode) system that is configured to emit light at a first wavelength, a first radiofrequency (RF) system that is configured to generate a first electrical signal, and a second RF system that is configured to generate a second electrical signal. The first RF system, the second RF system, and the LED system are configurable to operate in a first treatment mode, causing the device to provide the first electrical signal, the second electrical signal, and light at the first wavelength.

Abstract: A probe card inspection system uses a fiduciary plate having a plurality of targets deposited thereon by photolithography and vapor deposition. A plurality of semiconductor probe card probe tips are contacted with the fiducial pattern on the plate. An electronic imaging system determines the position of geometric centroids of the probe tips with respect to an index mark in the fiducial pattern. A central processor determines the position of each imaged probe tip(s) with respect to the index mark, and calculates the relative positions of each probe tip from that data.
