20110103337 | GPS-BASED MULTI-MODE SYNCHRONIZATION AND CLOCKING FEMTO-CELLS, PICO-CELLS AND MACRO BASE STATIONS - A method is disclosed for providing syntonisation, synchronization, position or some combination to a wireless base station, micro-cell, pico-cell, femto-cell or access point, by providing holdover backup in a GPS clock module via at least one interface between the GPS clock module and an external time or frequency reference. Switching between synchronization modes is designed to occur on the control side of the oscillator portion of the module rather than at the output of two oscillators. A corresponding GPS clock module apparatus is disclosed for providing holdover backup via at least one interface between the GPS clock module and external time or frequency references. | 05-05-2011 |

20090109088 | SATELLITE-BASED POSITIONING SYSTEM IMPROVEMENT - A method, device and system for determining a receiver location using weak signal satellite transmissions. The invention involves a sequence of exchanges between an aiding source and a receiver that serve to provide aiding information to the receiver so that the receiver's location may be determined in the presence of weak satellite transmissions. With the aiding information, the novel receiver detects, acquires and tracks weak satellite signals and computes position solutions from calculated pseudo ranges despite the inability to extract time synchronization date f, 'n the weak satellite signals. The invention includes as features, methods and apparatus for the calibration of a local oscillator, the cancellation of cross correlations, a Doppler location scheme, an ensemble averaging scheme, the calculation of almanac aiding from a table of orbit coefficients, absolute time determination, and a modified search engine. | 04-30-2009 |

20110226990 | PROCESS FOR PREPARING SILICA MICROPARTICLES - Silica core-shell microparticles are prepared by growing a porous silica shell from a silica precursor onto the surface of non-porous silica particle dispersed in a mixed surfactant solution under basic pH conditions. The particles are hydrothermally treating in an oil-in-water emulsion system and the particles are calcined to remove residual surfactants. Optionally, the particles of may be base etched to expand the size of the pores in the silica shell. Core-shell silica particles with an ordered mesoporous layer are produced. | 09-22-2011 |
