The present invention provides for improved parallel interference cancellation. An input signal composed of multiple user signals is processed over a select time duration. The input signal is separated into individual signals corresponding to each of the multiple users and demodulated to recover symbols for each of the individual signals. The recovered symbols are processed based on the consistency of previous estimates of the given symbol to provide weighted symbol estimates. The respective weighted symbol estimates for each of the users are modulated with the appropriate coding and processed using channel estimates to create individual, regenerated signals. For each user, the regenerated signals for the other users are subtracted from the original input signal to form new individual signals. The new individual signals are each demodulated and reprocessed for multiple iterations. The output of the last iteration is used to form the final symbol decisions for each user signal.

The invention provides a battery pack with an internal serial structure and a manufacture method thereof. The battery pack comprises N pole groups, N-1 baffles with conductivity, an electrolyte and sealing rings in a battery shell and top covers on the battery shell. The manufacture method comprises the following steps of: separating two adjacent pole groups with the baffles; connecting the anode of one pole group with a baffle; connecting the cathode of the other pole group with the other edge of the baffle; and serially connecting the adjacent pole groups. The battery pack is designed according to a needed voltage so that a plurality of unit battery cores are connected serially in the same battery shell for use as a whole to meet the voltage requirement. The battery pack provided by the invention has smaller battery size and lighter mass under the same voltage while meeting the voltage requirement on various electric appliances and has low requirement for a battery packing technology. Meanwhile, due to no connectors for conduction among cell batteries when the batteries are combined, the external short circuit of the batteries can be reduced.

A conformable paste comprising porous agglomerates of carbon black dispersed in a paste-forming vehicle is disclosed. The paste is useful as an interface material for improving the thermal contact between two proximate solid surfaces, such as the surfaces of a heat source and a heat sink. Upon compression between the two solid surfaces, the paste forms a material that enhances the thermal contact between said surfaces. This invention also discloses a conformable interface material which, upon compression between two proximate solid surfaces, forms a material that enhances the thermal contact between said surfaces. This interface material comprises (i) a sheet and (ii) a conformable, spreadable and thermally conductive paste on each of the two opposite sides of the sheet, said paste comprising porous agglomerates of carbon black dispersed in a paste-forming vehicle. In addition, a method of providing a thermal contact between two solid surfaces is disclosed. This method comprises disposing between and in contact with said surfaces a material comprising: a conformable, spreadable and thermally conductive paste comprising porous agglomerates of carbon black dispersed in a paste-forming vehicle, and applying a pressure to cause said material to conform to the topography of said surfaces.

Methods of bleaching mechanical pulp under alkaline conditions with hydrogen peroxide. The methods include introducing a source of magnesium ions and hydroxyl ions to a refiner. The wood particulates are refined into a pulp in the presence of the magnesium ions and hydroxyl ions, and optionally perhydroxyl ions to simultaneously refine and bleach the pulp in a refiner.
