    摘要： In a level sensitive scan design (LSSD) circuit embodiment for testing the behavior of logic circuits, a mechanism is provided for generating a skewed load of data into a set of shift register scan string latches. The nature of the input scan string assures that a certain number of 0 to 1 or 1 to 0 transitions occurs as an input to the block of logic being tested. Furthermore, a mechanism for delaying by one system clock cycle time the capture of information from the logic block in a second shift register scan string provides a mechanism for testing for the occurrence of short paths and long paths while preserving testability for stuck-at faults. Furthermore, all of these advantages are achieved without impacting the traditional stuck-fault test capabilities of the level sensitive scan design methodology.

    摘要： This invention pertains to methods for extracting and purifying zein, zein bodies, glutelins or destarched corn gluten from corn gluten meal by efficiently removing and recovering food grade pigments and starch hydrolysates, while discarding unwanted fractions. Corn gluten is subjected to the combination of enzymatic starch hydrolysis, alkaline treatment, alcohol washing and alcohol extraction to produce a substantially starch-free, deflavored and decolored zein which is suitable for use in foods and pharmaceuticals. An advantage of the process described herein is its use of food grade alcohol(s) to deflavor, decolorize and extract the zein from corn gluten meal. Purified zein and zein bodies have improved utility and functionality in a variety of existing and emerging food applications. Alternate products such as deflavored, decolored and destarched corn gluten, zein bodies or glutelins are also obtained by the methods of this invention and are useful as vegetable protein supplements. By-products of the invention such as yellow food pigments and starch hydrolysates can be further purified and/or used directly in various foods.

    摘要： A dynamically switchable clock system having a symmetrical output signal includes a frequency doubler which couples the input frequency to provide greater resolution and synchronization of an output signal to an input signal in the frequency divider and the facility to handle odd divides as even divides at double frequency, a counter controlled by a divisor select signal, first and second compare circuits which compare against the preprogrammed count for division, the compare circuits receiving an input from the divisor select circuits, and having outputs to a counter reset line and to an output clock S/R latch which provides the frequency divided symmetrical output signal.
