Abstract: Disclosed herein are devices, systems, and methods for treating a medical condition through a coordinated stimulation of two or more target nerves using a head worn apparatus. The apparatus may include an electrode assembly for neural stimulation of a plurality of target nerves, a substrate; a set of electrodes, having: a set of frontal electrodes including a superior frontal electrode and an inferior frontal electrode, the set of frontal electrodes positioned on the substrate such that the set of frontal electrodes are configured to overlie or straddle a supraorbital trigeminal nerve branch of the subject; or a set of lateral electrodes including a concha electrode and a tragus electrode, the set of lateral electrodes positioned on the substrate such that the set of lateral electrodes are configured to overlie or straddle an auricular branch of the vagus nerve of the subject.

Abstract: A set of symmetrically segmented square prism Permanent Magnet (PM) halves in a 45-45-90 triangular prism and a rectangular square prism with predefined 45° stepped magnetizations are designed as Fine Elements (FEs), bringing finely adaptive mosaicking advantages for array arrangement. Optimized Halbach effect FE PM pole modules in cuboidal and isosceles trapezoidal prism shapes are invented to provide an augmented one-side-operating field. Simulation data show that typical dual layer FE PM arrays generate high-fidelity sinusoidal waveforms within air-gaps with peak field strengths of up to 1.2 Tesla. Featuring a pole width-to-thickness ratio ranging from 1 to 6, FE PM motor tracks with a series of scale, format, and sectional features are constructed in lightweight ferrous and/or nonferrous structures, which energize OEM and/or FE current carrying winding coils to implement linear and curvilinear motors with high power/force/torque density and low force ripple.

Abstract: The present invention relates, in part, to heat transfer systems, methods and compositions which utilize a heat transfer fluid comprising: (a) HFO-1234ze; (b) HFC-227ea; and (c) optionally HFC-134a, wherein HFO-1234ze and HFC-227ea are provided in effective amounts to form an azeotrope or azeotrope-like composition.

Abstract: There is a working fluid for a heating and cooling. The fluid is a blend of from about 1% to about 98% by weight 1,1,1,2,3,3,3-heptafluoropropane, from about 1% to about 98% by weight 1,1,1,3,3,3-hexafluoropropane, and from about 1% to about 98% by weight 1,1,1,2-tetrafluoroethane. The 1,1,1,2,3,3,3-heptafluoropropane, 1,1,1,3,3,3-hexafluoropropane, and 1,1,1,2-tetrafluoroethane are from about 90% or more by weight of the blend. There are also an apparatus that uses the blend and methods for heating and cooling using the blend.

Abstract: A method and apparatus for improving dispersal performance of instruction threads is described. In one embodiment, the dispersal logic determines whether the instructions supplied to it include any NOP instructions. When a NOP instruction is detected, the dispersal logic places the NOP into a no-op port for execution. All other instructions are distributed to the proper execution pipes in a normal manner. Because the NOP instructions do not use the execution resources of other instructions, all instruction threads can be executed in one cycle.
