  • Patent number: 7156899
    Abstract: The present invention provides a power generation facility that is adapted to clean large air masses. Air from the environment, which normally contains the most pollutants, is directed into an air flow path through which large quantities of air are directed by a plurality of large diameter fans. The large air flow is directed through electrically insulated cooling fins which cool heated gas from power generators. The electrically insulated cooling fans have a voltage applied thereto and act as electrodes used to produce an electric field that attracts particles such as pollutants. In a preferred embodiment, a charging section is utilized within the air flow prior to the electrically insulated cooling fins to charge the particles with a charge opposite to the voltage applied to the cooling fins to thereby attract the particles to the cooling fins. A cooling fin washing system with pressurized jets is provided in one embodiment to wash the pollutants from the surface of the cooling fins.

  • Patent number: 6725621
    Abstract: The present invention is an improved power generation facility and method of construction. The improved power generation facility of the present invention provides a low impact implementation suitable for placement in or near a developed, populated area comprising ultimate consumers. The improved power generation facility comprises a foundation; a plurality of legs which form a support structure capable of supporting a plurality of condenser modules with cooling fans of predetermined size; and a housing for containing predetermined power generation equipment, the housing fitting inside the support structure and having a facade which can be made to blend into a surrounding environment's architecture. In a preferred mode, the legs are tricolumn legs that may be removably fastened to each other and to the foundation. Further, the housing may be suspended from the support structure and the plurality of cooling fans situated to minimize noise from the cooling fans.

  • Publication number: 20040002083
    Abstract: A method of predicting structural characteristics of a nucleic acid molecule. A method of predicting single-stranded regions in the secondary structure of a nucleic acid molecule in accordance with a probability distribution of structures based on recursively generated partition functions for the identification of accessible sites on target RNA for gene down-regulation and the rational design of antisense oligos, trans-cleaving ribozymes, siRNAss and antisense RNAs, for interaction with other RNA-targeting molecules, and for rational design of nucleic acid probes such as molecular beacons for RNA or DNA targets.

  • Patent number: 5555277
    Abstract: Improved gain control is obtained in each receiver of a LAN interface or hub in a LAN of the type using amplitude critical signals for conveying information. An evaluation circuit compares a signal representing a calibration value to a predetermined limits and adjusts the gain by one of a plurality of amplification levels to maintain a high level signals which are more accurately decoded into digital information. Improved noise cancellation is also obtained by creating a primary copy and an inverted copy of the received amplitude critical signal, amplifying the primary and inverted copy signals by the same predetermined amount and adding the amplified signals. The addition reinforces the value of the received amplitude critical signal while effectively subtracting the noise effects.

  • Patent number: 4276573
    Abstract: A pulse shaping network for the read circuitry of a floppy disc memory system in which encoded digital data is recorded in a double density format. The pulse shaping network processes an uncompensated input read signal in order to substantially eliminate cross talk between the bivalent pulses of the read signal, thereby correcting the peak phase shift and peak amplitude distortion that characterizes intersymbol cross talk. The resulting phase and amplitude corrected read signal can then be accurately decoded in order to retrieve the information contained in the peak phases of the read signal. The pulse shaping network includes a sine pulse-forming filter comprised of a capacitively terminated parallel cascade of series LC sections characterized by respective half-period harmonic transfer functions whose impulse responses are substantially finite time duration sine pulses of a successively odd multiple of half cycles.

  • Patent number: 4262257
    Abstract: A peak detecting network utilizes a passive integrating filter to translate the peaks of an input signal into zero crossings of a translation signal, while providing a high degree of noise rejection and preventing the build-up of a DC component in the translation signal. The peak detecting network includes a sine pulse-forming filter comprised of a parallel cascade of a DC shunt inductor, a plurality of series LC sections, and a terminating capacitor. The series LC sections are characterized by respective transfer functions whose impulse responses are substantially finite time duration sine pulses of a successive number of cycles. A rectifier network applies a rectified input signal to the sine pulse-forming filter. A buffer network taps the response of the LC section associated with a one-cycle sine pulse impulse response. The resulting translation signal has a positive-going zero crossing corresponding in time to the occurrence of a peak of the rectified input signal.
