The number of the discrete samples for the dimensional measurement of machined surfaces and their coordinates is investigated. Counter to intuition, there need not be quadratically more samples than in the case for sampling lines or curves. To justify this novel scheme, accuracy is defined as the discrepancy of a finite point set. Then, from number theory,(More)
This thesis describes tracking objects with low-level electric fields. A physical model is presented that describes the important interactions and the required mathematical inversions. Sophisticated hardware used to perform the measurements is described in detail. Finally, a discussion of the myriad applications for electric field sensing is described. The(More)
