Abstract: An inkjet recording element comprising an absorbent support, a porous base layer nearest the support, a porous ink-receiving intermediate layer above the base layer, and a porous ink-receiving upper layer above the intermediate layer. The base layer and intermediate layers are each present in an amount of at least 25 g/m2 and the total dry weight coverage of the base layer, the intermediate layer, and the upper layer is 60 to 130 g/m2 in order to handle high fluxes of ink compositions during printing and to provide high gloss upon calendering. Also disclosed is an advantageous method of making such inkjet recording materials.

Abstract: System and method for a multi-standard sigma-delta modulator. A preferred embodiment comprises an integrator coupled to a signal input, wherein the integrator is configured to sum a difference between an input signal and an output of the sigma-delta modulator. A dithering circuit, also coupled to the signal input, is used to produce a dithering sequence. A summing point combines an output of the integrator and the dithering circuit while a quantizer converts the combined outputs into one of several discrete levels. The sigma-delta modulator further comprises a reset circuit to reset the sigma-delta modulator if the integrator becomes saturated. The sigma-delta modulator, as described, is compatible with G.Lite, ADSL, and ADSL+ variants of the digital subscriber line technical standards.

Abstract: A receiver architecture featuring a decimation filter and a bypass around said decimation filter is disclosed along with a method for optimizing said receiver's sampling phase and programmable gain amplifier. Said method utilizes said receiver architecture to modify said receiver's receive path to simplify optimizations.

Abstract: System and method for improving trellis decoding in communications systems with finite constellation boundaries. A preferred embodiment for a received point of a tone when the tone represents a number of bits greater than three comprises determining if a received point lies outside of a specified region, wherein the specified region is dependent upon the number of bits, and transforming the received point if the received point lies outside of the specified region. The transformation moves the received point onto a boundary of the specified region, which can help in the correct decoding of the received point.
