Abstract: A superconductor device includes a high superconductivity transition temperature enhanced from the raw material transition temperature. The superconductor device includes a matrix material and a core material. The enhancing matrix material and the core material together create a system of strongly coupled carriers. A plurality of low-dimensional conductive features can be embedded in the matrix. The low-dimensional conductive features (e.g., nanowires or nanoparticles) can be conductors or superconductors. An interaction between electrons of the low-dimensional conductive features and the enhancing matrix material can promote excitations that increase a superconductivity transition temperature of the superconductor device.

Abstract: A singulator of the friction belt type capable of synchronous or asynchronous modes of operation is described. The singulator includes a buffer assembly for accepting a shingled stream of documents, a feeder pinch belt for extracting the first document from the buffer and a scanner for scanning the document as it passes through the feeder into an accelerator which is also a pinch belt. The accelerator accelerates the document to a constant speed leaving the singulator. A control means is provided which operates coupled to the feeder drive and the scanner so that the next upstream document is extracted a predetermine time after the first document leaves the accelerator.
