    Abstract: A scheme for reconstructing multiband signals that occupy a small part of a given broad frequency range under the constraint of a small number of sampling channels. The multirate sampling scheme (MRS) entails gathering samples at several different rates whose sum is significantly lower than the Nyquist sampling rate. The number of channels does not depend on any characteristics of a signal. The reconstruction method may or may not rely on the synchronization between different sampling channels. The scheme can be implemented easily with optical sampling systems. The optical pulses required for the under-sampling are generated by a combination of an electrical comb generator and an electro-absorption optical modulator

    Abstract: The present invention relates to a method, and system for implementing the method, for performing incremental validation of an XML document with respect to XML Schema key and keyref constraints, and handling the semantics dictated by the XML Schema specification. Several operations are defined that change the content of a document, i.e., add or remove nodes, or change the value of existing nodes. The present invention verifies whether performing such an operation would violate key or keyref constraints, and allows changing the document only if the operation maintains the validity of the document with respect to the constraints. The verification traverses only the parts of the document that may be affected by the change operation, and not the whole document. The invention maintains, in an efficient manner, data structures that hold information relevant to the validation of key and keyref constraints.

    Abstract: In recent years piezoelectric actuation has been identified as a promising means of driving miniature Stirling devices. It supports miniaturization, has a high power to volume ratio, can operate at almost any frequency, good electrical to mechanical efficiencies, and potentially has a very long operating life. This invention uses a valve-less hydraulic amplification, creating an oscillating pressure wave sufficiently large to drive a high frequency miniature pulse tube cryocooler. The actuator may be separated from the main body of the cryocooler. The system lack of rubbing parts in the power conversion processes.

    Abstract: The present invention introduces a new architecture for all-optical logic architecture. In this architecture the gate is partitioned into a linear front-end followed by a nonlinear back-end. The logic calculation is practically performed within the linear stage, easing the requirements placed on the non-linear part and thus reducing the gate complexity. The new structures provide flexibility and improved performance for the all-optical logic. The proposed scheme may be integrated optics/electronics. An important additional attribute of our all-optical logic family is reconfigurability, i.e. the ability of the hardware architecture or devices to rapidly alter the functionalities of its components and the interconnection between them as needed.
