A programmable multifunction electronic camera uses a commercial pixel digital energy sensor to generate detector element signal digital data normally generated by expensive, custom designed, detector element energy sensors. The method and system can enhance trading transparency and reduce monitoring and regulation costs by disclosing corresponding transaction types prices, submitted quantities, and matched and unmatched results to buyers and sellers in a spot, securities or futures market through a network computer. A processor is configured to process the first and second signals so as to generate and output a depth map of the object in registration with the color image. In another implementation, a discrete Fourier transform operation is performed using fast Fourier transform techniques to select the antenna weighting values. Abrasive machining one of the first or second portion includes communicating the first or second portion with the other of the first or second portion to form the opening through the substrate.
