Abstract: The invention relates to a cross-linked elastomer composition including: an ethylene/alpha-olefin multiblock copolymer comprising polymerized ethylene and alpha-olefin units, an elastomer including a block copolymer having at least two, identical or different, aromatic blocks which are separated by at least one elastomer block, and a cross-linkable polymer, for example, a diene elastomer. The invention also relates to a product including the composition, and to the use of such a product as a seal.

Abstract: Methods and apparatus are provided for testing digital circuits. In one implementation, a scan chain test structure is provided that includes a cell chain, a first scan chain, and a second scan chain. The first scan chain is operable to test digital circuitry within a first portion of the cell chain, and the second scan chain is operable to test digital circuitry within a second portion of the cell chain. The first scan chain is further operable to test digital circuitry within the second scan chain, and the second scan chain is further operable to test digital circuitry within the first scan chain.

Abstract: A circuit and method for expanding the pulse width of a signal based on the input signal's pulse width. A circuit generates a delay equal to the pulse width of the input signal for both a SHIFT and OUT signal, which are out of phase with each other. The delay is generated when a capacitor applies voltage to two control transistors in both the SHIFT and OUT blocks, reducing gate control in these transistors and generating a delay in the falling edge of these signals such that the pulse width of the SHIFT signal is reduced and the pulse width of the OUT signal is increased. The capacitor is charged by a transistor activated by the SHIFT signal. The pulse-doubling system is self-converging: when the SHIFT signal's pulse width is zero, the OUT signal's pulse width is doubled, and the capacitor's charging level is fixed since it is no longer charged by the transistor controlled by the SHIFT signal.
