Abstract: A method and apparatus arc disclosed for transferring multi-source/multi-sink control signals using a differential signaling technique. An “active” state is transferred on a multi-source/multi-sink control signal network by inverting the previous voltage level, and an “inactive state” is transferred by maintaining the previous level. A change in the voltage level associated with a given control signal indicates that at least one node on an SoC device is asserting the corresponding control signal. In order to detect a change in the signal state from a previous cycle, each node includes a memory element, such as a latch, for maintaining the previous state. In this manner, a voltage level from the next interval can be compared to the recorded state to detect a change of state indicating an assertion of the control signal by another node.

Abstract: A three-dimensional flexible deep molded structure is provided having at least one planar flexible textile non-woven substrate that has been processed through thermo-forming or calendaring equipment to form a multiplicity of compressible projections extending from the planar surface which return to their shape after being substantially compressed. The non-woven substrate preferably is a staple fiber based non-woven fabric manufactured from fibers with a diameter of less than 100 microns and a fiber length of 5 to 50 millimeters. The non-woven fabric preferably has a constant anisotrophy ratio fp between ?1/2 to +1/2.
