Apparatus And Method For High Bandwidth Laser-Based Data Communication

View page
US Patent:
6421154, Jul 16, 2002
Filed:
Oct 30, 2000
Appl. No.:
09/699319
Inventors:
Jean-Claude Diels - Albuquerque NM
Ralph Bernstein - Los Altos CA
Karl Stahlkopf - San Francisco CA
Assignee:
Electric Power Research Institute, Inc. - Palo Alto CA
International Classification:
H04B 1004
US Classification:
359180, 359181, 359188, 359158, 359159
Abstract:
A laser communication system includes a first laser to generate a laser signal with femtosecond pulses. A first grating spectrally disperses the femtosecond pulses of the laser signal. A modulator converts the femtosecond pulses of the laser signal into coded words. A second grating spectrally recombines the coded words of the laser signal. A first telescope launches the laser signal. A second telescope receives the laser signal. A second laser generates a set of reference pulses. A non-linear crystal combines the set of reference pulses and the laser signal so as to create an output signal only when the laser signal and the reference pulses temporally coincide. A detector records the output.

US Patent:
6501578, Dec 31, 2002
Filed:
Dec 18, 1998
Appl. No.:
09/215420
Inventors:
Ralph Bernstein - Los Altos CA
Thomas M. Chaffee - Los Angeles CA
Jean-Claude Diels - Albuquerque NM
Karl Stahlkopf - San Francisco CA
Assignee:
Electric Power Research Institute, Inc. - Palo Alto CA
The University of New Mexico - Albuquerque NM
International Classification:
H04B 1000
US Classification:
359154, 359159, 359109
Abstract:
A line of sight laser communication system includes a laser to generate a laser signal with femtosecond pulses. A first grating spectrally disperses the femtosecond pulses of the laser signal. A programmable mask converts the femtosecond pulses of the laser signal into coded words. A second grating spectrally recombines the coded words of the laser signal. A telescope then launches the laser signal. The launched laser signal is received at a receiving telescope. A second laser generates a set of reference pulses. A non-linear crystal combines the set of reference pulses and the laser signal to create an output signal only when the laser signal and the reference pulses temporally coincide. A camera records the output signal.

Power Control Interface Between A Wind Farm And A Power Transmission System

View page
US Patent:
6858953, Feb 22, 2005
Filed:
Oct 17, 2003
Appl. No.:
10/687795
Inventors:
Karl E. Stahlkopf - Honolulu HI, US
Assignee:
Hawaiian Electric Company, Inc. - Honolulu HI
International Classification:
F03D009/00
H02J003/00
US Classification:
290 44, 290 55, 363 34
Abstract:
A power control interface between an unstable power source such as a wind farm and a power transmission line employs an electrical energy storage, control system, and electronic compensation module which act together like an “electronic shock absorber” for storing excess power during periods of increased power generation and releasing stored energy during periods of decreased power generation due to wind fluctuations. The control system is provided with a “look ahead” capability for predicting power output (wind speed conditions) and maintaining energy storage or release over a “narrow-band” range despite short duration fluctuations. The control system uses data derived from monitoring the wind farm power output and the power transmission line, and employs system-modeling algorithms to predict narrow-band wind speed conditions. The power control interface can also use its energy storage capacity to provide voltage support at the point of injection into the power transmission system, as well as fault clearance capability for “riding out” transient fault conditions occurring on the power transmission line.

US Patent:
8061132, Nov 22, 2011
Filed:
Aug 25, 2010
Appl. No.:
12/868701
Inventors:
Danielle A. Fong - Berkeley CA, US
Stephen E. Crane - Santa Rosa CA, US
AmirHossein Pourmousa Abkenar - Irvine CA, US
Kartikeya Mahalatkar - Oakland CA, US

Assignee:
Lightsail Energy, Inc. - Oakland CA
International Classification:
F01B 21/02
F03C 1/00
US Classification:
60417, 60407, 417438
Abstract:
A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the “pressure cell”) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.
