A radiofrequency identification (RFID) device includes an active RFID tag that includes a power source and a passive RFID tag reader, the passive RFID tag reader electrically coupled to the power source of the active RFID tag.

Passive RFID assisted active RFID tag

The system contains a plurality of laser projectors. An image of a marking is projected in a synchronized form by the plurality of laser projectors. A computer network provides communication with the laser projectors. A central workstation communicates with the laser projectors through the computer network. The central workstation coordinates the image projected by the laser projectors.

The present invention provides a method and apparatus for use in measuring a thickness of a layer and/or variations in layer thickness for layers that are flat, curved or have curves. The apparatus comprises a light source to generate a light beam, a light beam detector to detect at least a portion of the light beam reflected, an eddy current field generator that induces an eddy current, an eddy current detector to detect the induced eddy current and a processor coupled with the light source, light detector, eddy current field generator and eddy current detector, wherein the processor controls the light detector, eddy current field generator and eddy current detector. A radial characteristic of a region of the surface can be determined, a scaling factor can be determined based on the radial characteristic and a measured distance can be scaled based on the scaling factor in determining a thickness.
