Abstract: Various aspects and examples are directed to methods and systems for interpolation in systems that execute non-linear quantization routines. Particular aspects of the methods described herein include a method of detecting a Radar Cross Section (RCS) and a method of detecting patient injuries. In one example, a method of detecting RCS includes receiving a sequence of samples at a re-visit rate of a radar antenna, the sequence of samples being based on electromagnetic energy reflected from a target, interpolating a model curve to the sequence of samples, where each sample of the sequence of samples geometrically increases in value relative to a previous sample of the sequence of samples, comparing the model curve to a calibrated curve and determining a shift between the model curve and the calibrated curve based on the comparison, and detecting a RCS based on the shift between the model curve and the calibrated curve.

Abstract: An embodiment of a semiconductor wafer includes a semiconductor substrate, a plurality of through substrate vias (TSVs), and a conductive layer. The TSVs extend between first and second substrate surfaces. The TSVs include a first subset of trench via(s) each having a primary axis aligned in a first direction, and a second subset of trench via(s) each having a primary axis aligned in a second and different direction. The TSVs form an alignment pattern in an alignment area of the substrate. The conductive layer is directly connected to the second substrate surface and to first ends of the TSVs. Using the TSVs for alignment, the conductive layer may be patterned so that a portion of the conductive layer is directly coupled to the TSVs, and so that the conductive layer includes at least one conductive material void (e.g., in alignment with a passive component at the first substrate surface).
