Abstract: A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Abstract: Various embodiments of layout tool devices and systems are provided. In various embodiments, the layout tool devices and systems improve layout work flow using layout tools, such as via using lasers and/or customized flexible elongate structures to facilitate marking points along a line, including systems with multiple devices, such as mobile devices, that emit lasers in combination with the other devices in the system.

Abstract: A resilient mat system where a mat has overall mat thickness T, and the mat has an upper layer with an upper layer thickness t, and a plurality of supporting resilient substructure columns, each column having a relatively uniform height h, such that T=t+h, wherein the ratio of h:t>3.5 for values of T>about 0.9 inch (about 2.3 cm). Each column has a frusto-conical column wall, a central void, and a column bottom. The frusto-conical column has its smaller diameter end at the column bottom, a plurality of the columns optionally further have a vertical stiffening rib along a portion of the upper zone of the column wall.

Each column has a column wall that surrounds a central void in the column with the void opening at a bottom of the column. The column has lower zone that is a more compressible, relatively collapsible zone, and an upper zone that is a less compressible, relatively uncollapsible zone. There is a fenestrated mat connector with connector fenestrations sized and numbered to receive the bases of a plurality of columns from two mats therein.

Abstract: A resilient mat system has at least one mat with a mat thickness T, an upper layer with an upper layer thickness t, and a plurality of supporting resilient substructure columns, each column having a relatively uniform height h, such that T=t+h, wherein the ratio of h:t>3.5 for values of T> about 0.9 inch. Each column wall surrounds a central void in the column, the void opening at a bottom of the column. The column has in a bottom region of the column wall a lower zone that is a more compressible, relatively collapsible zone, and in an upper region of the column wall above the lower zone an upper zone that is a less compressible, relatively uncollapsible zone. The resilient mat system optionally has a relatively rigid ramp structure bordering at least one mat on at least two sides, and the ramp structure is preferably attached to a floor base to retain the mat, whereby the mat is removable from the border of the ramp. Alternatively, the ramp structure is attached to at least a portion of the mat.

Abstract: Apparatus for catalytic cracking of a selected portion of a hydrocarbon feedstock comprising a riser reactor and a catalyst regenerator, a regenerated catalyst cooler, and an absorber. Regenerated catalyst from the catalyst regenerator is conducted through the catalyst cooler into the absorber where it adsorbs hydrocarbon cracking feedstock and then returned to the riser reactor. A duct carries part of the hot regenerated catalyst from the catalyst regenerator directly to the riser reactor to supply heat for cracking the hydrocarbon feedstock.

Abstract: An improved method for fluidized catalytic cracking of a selected portion of a paraffinic hydrocarbon feedstock in which a paraffinic chargestock for a fluid catalytic cracking unit is processed for the separation of at least a part of its paraffinic components from non-paraffins by means of a zeolite composition which acts both as a molecular sieve and a cracking catalyst. The paraffins-containing fraction adsorbed on the molecular sieve is subjected to catalytic cracking in a riser-type fluid catalytic cracking reaction zone at a temperature in the range of 650.degree. to 700.degree. C. under subatmospheric pressure conditions for the production of light olefins.

Abstract: A two-stage cascade flow fluid catalytic cracking process capable of converting high molecular weight hydrocarbons containing catalyst poisons into products of lower molecular weight with high activity cracking catalyst susceptible to catalyst poisons, the cascade flow process resulting in higher yields of desired motor fuel fractions than those obtainable with conventional riser flow fluid catalytic cracking processes. Catalyst poisons, e.g.

Abstract: A process for conversion of paraffinic base petroleum cracking stocks to high octane motor fuels and petrochemical feedstocks in which paraffinic components are separated from the cracking stock to yield a deparaffined fraction which is hydrotreated and catalytically cracked and a paraffin fraction which is separately catalytically cracked whereby improved yields of normally gaseous olefins and normally liquid products including high octane motor fuel components are obtained.

Abstract: This invention relates to an adaptive demodulator for use in a phase shift keyed microwave communication system. The adaptive demodulator improves the system error rate at a particular carrier to noise ratio by monitoring the output of the demodulator and optimizing the phase offset of the carrier signal recovered in the demodulator to provide a high output. A particular example continuously varies the phase offset of the recovered carrier signal about the highest output value to track variations in the optimum phase offset.
