A non-destructive approach for the 3D localization of buried hot spots in electronic device architectures by use of Lock-in Thermography (LIT). The 3D analysis is based on the principles of thermal wave propagation through different material layers and the resulting phase shift/thermal time delay. With more complex multi level stacked die architectures it is necessary to acquire multiple LIT results at different excitation frequencies for precise hot spot depth localization. Additionally, the use of multiple time-resolved thermal waveforms, measured in a minimized field of view on top of the hot spot location, can be used to speed up the data acquisition. The shape of the resulting waveforms can be analyzed to further increase the detection accuracy and confidence level.

Embodiments of the invention are directed to a system arrangement and method for the optical control of the work result of a tool and/or guiding the tool with all-around view, wherein tool and workpiece are moved relative to each other, along a straight path or, particularly, on curved path. According to an aspect, the tool is positioned centrically in the image field and a tool support is located centrically in the beam path or in a pupil of the optics, or in an optical vicinity of the pupil. An arrangement for 3D analysis is also indicated. Advantageously, only one camera need be used, providing a lean design of viewing and illumination, and usable under cramped space conditions. Guiding, processing and control are possible in a single operation using a single camera. Methods for, e.g., applying viscous masses, welding, deburring, and related applications are also disclosed.

A method and system for allowing owners of a physical work, such as a book, to purchase an electronic version of the work by validating their ownership of the work using a personal electronic device, such as a smartphone, and marking the work. The owner is instructed to mark the work and to capture camera images of the work. The images are analyzed to identify the work, determine whether the work has been previously marked, and to verify that the work has been marked by the owner. Analysis may be performed remotely by a server in communication with the personal electronic device. Various means for authenticating ownership of the work are also disclosed, including 3D analysis, page curvature analysis, concurrent still image and video capture, detection of use of a video display to spoof the work, and geofencing.

The invention relates to a measurement technology for establishing a reference coordinate system of a sheet metal part. The method includes the following steps: under the condition that there is no digital model of the part, the existing sheet metal part is used to measure the key hole position or the surface point data of the part by three coordinates as the nominal value, and by setting a set of reference points , respectively measure the part features of the body-in-white and the complete vehicle; use the measured data to fit the measured value and the nominal value of the three coordinates, verify, and analyze the deviation of the reference point on the complete vehicle relative to the body-in-white in all directions; At the same time, analyze other characteristic positions, and determine whether the reference system is reasonable or not by setting corresponding thresholds. If it is satisfied, keep the reference feature combination. If it is not satisfied, then analyze the 3D distance of each feature position, and select a set of features with a small 3D distance deformation as the reference coordinate system for measurement; by comparing the deviation of the reference feature combination Size, select a group of features to establish a datum coordinate system.
