20150109008 | METHOD FOR CONTROLLING THE SIZE OF SOLID-STATE NANOPORES - A method is provided for precisely enlarging a nanopore formed in a membrane. The method includes: applying an electric potential across the nanopore, where the electric potential has a pulsed waveform oscillating between a high value and a low value; measuring current flowing though the nanopore while the electric potential is being applied to the nanopore at a low value; determining size of the nanopore based in part on the measured current; and removing the electric potential applied to the membrane when the size of the nanopore corresponds to a desired size. | 04-23-2015 |

20140177609 | Generation of Digital Clock for System Having RF Circuitry - Circuitry for any of a transceiver, a transmitter, and a receiver, has radio frequency (RF) circuitry, digital circuitry, a carrier signal generator to provide a carrier signal to the RF circuitry and a clock generator for generating a digital clock for clocking at least some of the digital circuitry. The RF circuitry is susceptible to interference from harmonics of the clocking, and the clock generator derives a frequency of the digital clock based on a frequency divided down from a frequency of the carrier signal so that the interference to the RF circuitry occurs at frequencies which are harmonics of the carrier signal. | 06-26-2014 |

20120159867 | Elevated Platform Systems Including Fiber Reinforced Composite Panels - An elevated platform system includes a base support structure and a plurality of fiber reinforced polymer composite panels. The base support structure includes pilings secured to a ground surface and attachment cradles coupled to the pilings. The attachment cradles are in electrical continuity with the ground surface. The fiber reinforced polymer composite panels include a panel body portion, fibrous material surrounding the panel body portion, a non-conductive matrix forming at least a portion of an outer-most layer of the fiber reinforced polymer composite panel, and an electrically-conductive layer at least partially embedded in the non-conductive matrix. The fiber reinforced polymer composite panels are coupled to the attachment cradles, such that the electrically-conductive layer of the fiber reinforced polymer composite panel is in electrical continuity with the ground surface. | 06-28-2012 |
20150013119 | INTERLOCKING DEVICE FOR GROUND COVER MATS - The invention is directed to an interlocking device for releasably connecting ground a first and a second ground cover mats each having tubular members. The device includes two clamping arms and a securing means. The clamping arms each have a collar member to engage one of the tubular members. The collar members are adjustably connected to each other to move the device from an open installation position into a closed restraining position in which the concave surfaces restrain the tubular members and are opposed to each other. The securing means releasably locks the clamping arms in the closed restraining position. | 01-15-2015 |
