A configurable circuit of the present invention includes a plurality of logic blocks, and a programmable bus which can program connections of plurality of logic blocks. A subsidiary feedback path is provided directly from the output of the circuit’s VCO. Likewise, when the cord is retracted back into the case of the retractable modem cord device, the design spins. The second state is configured to interrupt the bubble field to collapse the bubble field based on the trend of the at least one detected tissue property. The method also involves displaying parameter information associated with the one of the plurality of wavelet coefficient quantities to represent the probabilistic data.
