Abstract: Interpreting data obtained by analysis of nucleic acids (DNA) by obtaining nucleic acid data in a spatial domain, transforming the nucleic acid data from the spatial domain into a frequency domain, and obtaining sequence data of the nucleic acid data by executing a data mining process on the transformed nucleic acid data. The transformation may be performed by a Hadamard transform, a Fourier transform or a Wavelet transform to obtain frequency coefficients, with less than all of the frequency coefficients being utilized in the data mining process. In addition, the frequency domain data may be normalized prior to the data mining process. The data mining process may be subjecting the frequency coefficients to a connectionist (neural network) algorithm or to a classification tree/rule induction (CART) algorithm.

Abstract: An improved ringing generator is disclosed, for producing and transmitting an AC ringing voltage waveform to a subscriber line from a negative and positive DC voltage source. The ringing generator is characterized by a transformer having a primary winding and a secondary winding. The primary winding includes a plurality of taps dividing the primary winding into a plurality of winding segments. The secondary winding is connected to subscriber line via a filter network. Each winding segment is connected to a buffer-driver which has a first lead connected to the DC voltage source and a second lead connected to a source of control signals. Responsive to the control signals a selected pair of buffer-drivers are alternatively enabled connecting for a predetermined time period the associated coupling segments to the DC voltage source thereby, producing a switched ringing voltage waveform which is coupled to the secondary winding.

Abstract: A two amplifier subscriber line interface circuit that uses a novel voltage divider technique for providing power to the two lower voltage amplifiers from a 50 volt central office battery. This is achieved by using one lower power amplifier with a Zener regulator diode in shunt thereof to regulate its current.
