Abstract: A system and method for Displacement Current Phase Tomography. The present system invention obtains a linear relationship between mutual displacement current from a sensor (output current of the measuring electrode terminals) and the area (or volume) of an object to be imaged in the imaging domain. The system uses capacitance sensors and utilizes the phase of the measured current, in addition to the amplitude, to reconstruct an image.

Abstract: The present invention uses a plurality of magnetic field sources and magnetic field sensors mounted against a surface. Based on the mass of ferromagnetic material, such as steel, the magnetic field sensors detect variable magnetic field strength and this variance is proportional to the mass of ferromagnetic material being detected. An electronic device reads the magnetic field values and uses the information to quantify the ferromagnetic material in the surface or inside the volume of the construction component.

Abstract: A measurement and control system for controlling system functions as a function of rotational parameters of a rotating device includes a plurality of interval markers distributed around the periphery of the rotating device and fixed relative to the device support. The measurement and control system also includes a plurality of sensors attached to the periphery of the rotating device, fixed relative to the rotating device so as to be in close proximity to the interval markers. Measurements from sensors attached to different locations on the rotating device are combined so as to mitigate variations in angular speed of the device. Measured rotational parameters are used to predict, via linear interpolation, angular positions of the device between those positions measured by the sensors.
