  • Patent number: 6307884
    Abstract: An apparatus and method for improving error rate performance in a communication channel utilizes a dual decision feedback equalizer (DDFE) through the application of selective attenuation. An improved DDFE comprises first and second decision feedback equalizers (DFEs) operably connected in parallel to receive a series of input signals zk. The DFEs independently generate two series of decisions â ;1k and â ;2k in relation to peak magnitudes of the series of transmitted signals zk by filtering the series of decisions â ;1k and â ;2k to generate filtered outputs (a*p)1k and (a*p)2k based on previous decisions, and summing the filtered outputs (a*p)1k and (a*p)2k with the transmitted input series zk to generate two series of decision variables ã1k and ã2k, to remove effects of intersymbol interference.

  • Patent number: 5855922
    Abstract: Compositions and processes for the prophylaxis and therapeutic treatment of wounds, chronic non-healing wounds, burns, disease and other dermal disorders are disclosed. The compositions of the present invention comprise aqueous solutions of a metal chlorite having a concentration of from about 0.002% to about 0.5% by weight of metal chlorite. The process of the present invention comprises treating the dermal disorder with an aqueous solution of from about 0.002% to about 0.5% by weight of a metal chlorite. Wounds, chronic non-healing wounds, burns and other dermal disorders treated in this manner heal more quickly and with reduced scar formation. The antiseptic compositions and processes of the present invention exhibit anticollagenous activity such that the characteristics of the healed skin, such as elasticity and tensile strength, are similar to undamaged skin.
