20150083178 | SEEBECK/PELTIER THERMOELECTRIC CONVERSION DEVICE HAVING PHONON CONFINEMENT LAYERS OF CRYSTALLINE SEMICONDUCTOR CONTAINING ANGSTROM-SIZED ORGANIC GROUPS AS SEMICONDUCTOR ATOMS SUBSTITUENTS WITHIN THE CRYSTAL LATTICE AND FABRICATION PROCESS - Significant phonon migration restraint is achieved within a relatively homogeneous polycrystalline doped semiconductor bulk by purposely creating in the crystal lattice of the semiconductor hydrocarbon bonds with the semiconductor, typically Si or Ge, constituting effective organic group substituents of semiconductor atoms in the crystalline domains. An important enhancement of the factor of merit Z of such a modified electrically conductive doped semiconductor is obtained without resorting to nanometric cross sectional dimensions in order to rely on surface scattering eventually enhanced by making the surface highly irregular and/or creating nanocavities within the bulk of the conductive material. A determinant scattering of phonons migrating under the influence and in the direction of a temperature gradient in the homogeneous semiconductor takes place at the organic groups substituents in the crystalline doped semiconductor bulk. Fabrication processes and Seebeck-Peltier energy conversion devices are exemplarily described. | 03-26-2015 |

20110066154 | Surgical File Instrument Construction with Mechanism to Convert Rotary Motion to Reciprocal Motion - A surgical file instrument comprising a file, file guide, an outer split casing, a motion converter converting rotary motion to reciprocal motion and file assembly. The file assembly consists of an angular shaped elongated tube fairing into a generally flat portion defining the guide for the blade of the file, a complementary shaped file and a plastic rod insert having a lumen for the file and a lumen defining a passage for flowing a fluid to the surgical site. The motion converter consists of a planetary gear system connected to the battery powered motor that rotates a platen which in turn drives a cam and cam follower fitted into the cam slot for driving a drum for producing rectilinear motion. The file assembly is attached to the drum for reciprocating the file blade for use in a medical procedure for removing bone or a portion thereof. | 03-17-2011 |
20110066155 | Surgical file - A surgical file instrument including a surgical file assembly having an elongated tubular member with a guide/shield supporting the blade of the surgical file and being formed on the distal end thereof, the guide/shield portion being generally planar shaped and having an elongated longitudinally extending dimple defining a rail for guiding said blade and keeping it central and preventing wobbling. The side edges of said guide/shield extend upwardly and bear against the underside of the blade for supporting the same. | 03-17-2011 |
20130338670 | SURGICAL FILE - A surgical file instrument including a surgical file assembly having an elongated tubular member with a guide/shield supporting the blade of the surgical file and being formed on the distal end thereof, the guide/shield portion being generally planar shaped and having an elongated longitudinally extending dimple defining a rail for guiding said blade and keeping it central and preventing wobbling.

20110101972 | Gradient Magnetometer Atom Interferometer - Measuring a magnetic gradient according to the present invention includes generating a beam of like atoms with magnetic sublevels, applying a first pulse of electro-magnetic radiation to the beam of atoms to create a coherent superposition of the magnetic sublevels in the atoms in which the superposition results in a plurality of beams following separate paths and in which at least two of the paths are arms of an interferometer, applying a second pulse of electromagnetic radiation to both beams of atoms a time T later with characteristics substantially similar to the first pulse and in which the product of the Rabi frequency and T now must equal π (versus π/2 in the first pulse), whereby the states of the atoms in the two arms of the interferometer are coherently interchanged and are redirected towards each other. The beams of atoms are then recombined by apply a third pulse of electromagnetic radiation a time T±Δt after the second pulse with characteristics substantially similar to the first pulse such that the paths form a closed loop. Then, a detecting pulse of light is used to detect the number of atoms in one magnetic sublevel versus another magnetic sublevel. | 05-05-2011 |

20100012770 | System and Method for Improved Rotor Tip Performance - Embodiments of systems and methods for enhancing the performance of rotary wing aircraft through reduced torque, noise and vibration are disclosed. In one embodiment, a method includes configuring the rotorcraft in a selected flight condition, communicating input signals to a control system operable to position sails coupled to tips of blades of a rotor assembly, processing the input signals according to a constraint condition to generate sail positional information, and transferring the sail positional information to the sail. Alternately, input signals may be communicated to a control system operable to position a plurality of sails, each sail having an aerodynamic shape and positioned proximate to a tip portion of the rotor blade. The input signals may be configured to rotate each sail about a longitudinal axis into a corresponding pitch angle independently of the other sails. | 01-21-2010 |
