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: Instructions and logic provide advanced paging capabilities for secure enclave page caches. Embodiments include multiple hardware threads or processing cores, a cache to store secure data for a shared page address allocated to a secure enclave accessible by the hardware threads. A decode stage decodes a first instruction specifying said shared page address as an operand, and execution units mark an entry corresponding to an enclave page cache mapping for the shared page address to block creation of a new translation for either of said first or second hardware threads to access the shared page. A second instruction is decoded for execution, the second instruction specifying said secure enclave as an operand, and execution units record hardware threads currently accessing secure data in the enclave page cache corresponding to the secure enclave, and decrement the recorded number of hardware threads when any of the hardware threads exits the secure enclave.

Abstract: A method of and system for rapidly locating all passive underground electronic marker types in an area under survey may locate various marker types simultaneously. In accordance with one aspect of the present invention, a marker locator may sequentially transmit and receive multiple frequencies very quickly; alternatively, the transmitter may transmit a broadband signal on multiple frequencies.

Abstract: A method of and system for locating a single passive underground marker type may distinguish false indications caused by other marker types. In accordance with aspects of the present invention, minimization or elimination of false marker indications may be accomplished by processing the response from a marker to determine which frequency has the largest response.

Abstract: A method and an apparatus for detecting signals in an electromagnetically noisy environment by detecting electromagnetic signals comprising a noise signal and a known signal, and compressing the electromagnetic signal to thereby generate a compressed signal. The compressed signal is filtered to generate a filtered signal comprising substantially the known signal, and the filtered signal is expanded.

Abstract: The marker has a housing, an inner member and a tuned circuit. The housing has a spherical cavity therein. The inner member is located inside of the housing cavity and is rotatable therein. The tuned circuit has an inductance in the form of a coil as well as a capacitance. The tuned circuit is tuned to a particular frequency. A weight is coupled with the inner member and is eccentrically located within the spherical cavity. The eccentrically located weight seeks the lowest portion of the housing cavity. Thus, when the marker is manipulated so as to disorient the tuned circuit, the weight will rotate the inner member back to its stable position so as to properly orient the tuned circuit coil.

Abstract: A passive electrical marker has tuned circuits, each of which includes a coil and a capacitance. The tuned circuits are oriented with respect to each other in a predetermined arrangement so as to provide a broader spatial response. A foamed core inside of the tuned circuits maintains the tuned circuits in their respective orientations and protects the tuned circuits from mechanical shock. A shell or housing around the foamed tuned circuits provides environmental protection to the tuned circuits. The tuned circuits can be foamed together in a mold and then placed into the housing. Alternatively, the tuned circuits can be foamed together inside of a housing, which housing maintains the orientations between the tuned circuits during foaming. As still another alternative, the housing can be applied to the outside of the foamed tuned circuits as a coating.

Abstract: A modular fixturing system is provided, whose typical use is holding each of a series of similar workpieces, such as rough castings, during machining. It is conventional to support such workpieces during machining on permanent fixtures, specially designed for each type and size of workpiece, each such fixture utilizing two or more locating pins through parallel bores in the workpiece. In the present invention, locating pins are not part of any permanent fixture; instead, using a fixturing plate drilled with bores at modular intervals, the present adaptors are secured at any required spacing, and locating pins of desired diameter are mounted in them. One of the adaptors, referred to as "fixed", is mounted directly to one of the modular bores of the fixturing plate. The other adaptor to be used will be one whose position is slidably adjustable along linearly aligned slots in its base.

Abstract: An adjustable adapter, expecially useful for modular fixturing has provisions for mounting a variety of types and sizes of spring stop buttons and spring locating pins. These are secured in linear alignment with a slot in the adaptor base. When used to press a workpiece against stops, the reaction of their applied spring force is directed precisely along the line of this base slot. A single bolt in the slot thus suffices to secure the adaptor to a base plate, because this reaction causes no twisting moment about the point of bolting. Since only one bolt is required in the slot, the adaptor is compact and well suited for use with a modular fixturing plate; the slot length need be no longer than half the modular spacing of the plate bores.

Abstract: In a method of operating a photochemotherapy chamber for the irradiation of a patient with long wave ultraviolet light, a prescribed dosage is first selected. The prescribed dosage is then automatically converted into the time duration that an ultraviolet source should be energized to deliver said dosage by monitoring the line voltage and the total hours of operation of the ultraviolet source and adjusting said time duration accordingly.
