Abstract: A Multiform Suspension Microgranular Bioreactor (MSMB) is used to detect nucleic acids or peptides/proteins in molecular and biological samples. Polymer-based microgranules, coupled with biomass molecule probes, are constructed with different features. The biomass molecule probes include cDNA probes, oligonucleic acid probes, peptide or protein probes. These microgranules are differentiated according to their features including shape, size, color, fluorescence intensity, magnetic property, gravity, chemical luminal intensity, radioactivity, and other labels. The above microgranules are suspended in a sample solution and are used collectively as a microarray-like bioreactor device. Such MSMB-based microarrays are particularly useful in complicated biological detection assays with flow cytometry.

Abstract: A two-step training method for the estimation filter in the echo cancellation (EC) path of the analog front-end (AFE) circuit for a modem, such as an asymmetric digital subscriber line (ADSL) modem. During the first step, the transmit (TX) path is turned off and a digital TX signal (e.g., a pseudo white gaussian noise signal) is applied to the EC path essentially bypassing the EC estimation filter. During the second step, the EC path is turned off and a digital TX signal (e.g., the same pseudo white gaussian noise signal) is applied to the TX path. Coefficients for the EC estimation filter are then generated based on the digital RX signals recorded during the two training steps. In particular, the recorded digital RX signals are transformed to the frequency domain, where one is divided into the other. The resulting digital signal is then transformed back to the time domain, where it is used to generate the coefficients for the EC estimation filter.

Abstract: A method of designing an equalizer having a target response suited to a particular subclass of communication channels to shorten the duration of the impulse response of the overall transmission system, a class of channels being divided into a number of subclasses, each subclass having a fixed set of parameters selected to achieve the target response of the equalizer for that particular subclass of channel, the method comprising the steps of recognizing the subclass of the channel; and identifying the fixed set of parameters for the equaliser to achieve the target response by reference to a look-up table based on the subclass of the channel.
