Among other things, one or more techniques or systems for evaluating a tiered semiconductor structure, such as a stacked CMOS structure, for misalignment are provided. In an embodiment, a connectivity test is performed on vias between a first layer and a second layer to determine a via diameter and a via offset that are used to evaluate misalignment. In an embodiment, a connectivity test for vias within a first layer is performed to determine an alignment rotation based upon which vias are connected through a conductive arc within a second layer or which vias are connected to a conductive pattern out of a set of conductive patterns. In this way, the via diameter, the via offset, or the alignment rotation are used to evaluate the tiered semiconductor structure, such as during a stacked CMOS process, for misalignment.

An operator controlled wire rope maintenance apparatus for remotely discerning and locating wire rope wear problems.

In order to characterize electrically conducting and/or ferromagnetic objects, such as rebars, in concrete, a device is rolled along a surface of the sample. The device comprises e.g. two rows (10.1, 10.2) of partially overlapping sending coils (6) and receiving coils (7). Each pair of attributed sending and receiving coils (6, 7) is designed to have reduced mutual impedance in the absence of any electrically conducting and/or ferromagnetic object. The complex value, e.g. the phase and absolute value, of the mutual impedances are measured in order to determine a number of parameters (size, position and coverage of the object with concrete) of the objects.

In a method of determining a radius or diameter of a train wheel, a camera mounted on a train acquires first and second images (pictures) of first and second objects spaced along a path being traveled by the train. Matches are then determined between the first and second objects appearing in the first and second acquired images and representations (pictures) of the first and second objects appearing in prerecorded images included in a track database that include corresponding first and second geographical locations. A distance L traveled by the train between the first and second geographical locations is determined and a sum C of electrical pulses generated by an encoder coupled to the train wheel during travel of the train the distance L is determined. Based on the distance L and the sum C, a diameter or radius of the wheel is determined.
