  • Method and amplification circuit with pre-emphasis
    Patent number: 6853220
    Abstract: A method for amplifying a digital signal representative of data to be transmitted by a line driver with pre-emphasis over an output line is provided. The gain of the line driver is varied between an upper value to coincide with switching of the digital signal and a lower value in absence of the digital signal switching. In particular, the varying includes amplifying the digital signal with a first gain for generating an amplified digital signal, delaying the digital signal with a predetermined delay for generating a delayed digital signal, and amplifying the delayed digital signal with a second gain for generating a delayed and amplified digital signal. An ouput signal corresponding to a difference between the amplified digital signal and the delayed and amplified digital signal is output over the output line.

  • Method of producing bars composed of milk and simple and complex sugars
    Patent number: 4759940
    Abstract: The method consists of intimately dry mixing a set amount of powdered milk with a set amount of ground microcrystalline sugar as binder alone or with one or more carbohydrates selected from a group including glucose, fructose, maltose, sucrose, matoldextrines, and maltitol, and of compressing the mixture into a bar. Fluorine and/or flavoring matter, such as cocoa, coffee, strawberry flavor, mint flavor, are added to the mixture prior to its compression. The resulting bars are in the form of square-based parallelepipeds with rounded corners.
