    • Systems and methods are described for transmitting a waveform having a controllable attenuation and propagation velocity. An exemplary method comprises: generating an exponential waveform, the exponential waveform (a) being characterized by the equation Vin=De−ASD[x−vSDt], where D is a magnitude, Vin is a voltage, t is time, ASD is an attenuation coefficient, and vSD is a propagation velocity; and (b) being truncated at a maximum value. An exemplary apparatus comprises: an exponential waveform generator; an input recorder coupled to an output of the exponential waveform generator; a transmission line under test coupled to the output of the exponential waveform generator; an output recorder coupled to the transmission line under test; an additional transmission line coupled to the transmission line under test; and a termination impedance coupled to the additional transmission line and to a ground.

    • An optical information processing circuit assembly includes an optically transmissive substrate and a resiliently compressible circuit member affixed to the substrate and defining an opening therethrough with a number of leads disposed about the opening. An integrated imaging circuit defines a corresponding number of pads wherein the pads align with and electrically contact the leads. An optically transmissive medium may be disposed between and in contact with the substrate and the integrated imaging circuit to allow light transmission therethrough from the substrate to the imaging circuit. In one embodiment, resilient bumps are provided between the integrated imaging circuit and the resiliently compressible circuit member to form the electrical connection therebetween. Alternatively, solder bumps may replace the resilient bumps. Additional circuit components may be similarly mounted to the resiliently compressible circuit member to complete the assembly.
