Title: Method and circuit arrangement for operating a sodium high-pressure lamp
Inventor: BONIGK MICHAEL
IPC: H05B41/288
Filed: 2001-07-09
Abstract: Sodium high-pressure lamps can be operated using a circuit, which rectifies the a.c. supply voltage and which, while eliminating smoothing, feeds the supply voltage directly to a power inverter for generating a frequency great er than 1 kHz. The voltage that is modulated to double the power-line frequency  is supplied via an HF inductive resistor and via an ignition transmitter to the lamp, which is preferably filled with xenon to a pressure exceeding 1 ba r. The savings in electric energy for the system lamp ballast is equal to 30 % compared to a choke-operated Hg-free standard lamp having the same luminous flux. The use of a microprocessor for controlling the half bridge enables an  externally controlled or automatic power reduction with an additional potential of savings in electric energy equal to an annual mean of 35 % and enables an end of life shutdown of the system in order to prevent cycling.</ SDOAB>

Title: Domestic solar reflector water heater system
Inventor: CARROLL NEIL
IPC: F24S23/71
Filed: 2002-05-14
Abstract: An assembly or system which is capable of heating water by the sun's energy in an arrangement that circulates the water from a holding tank through the focal point of a solar reflector dish.      The Problem The largest single cost for domestic energy is often the energy used in heating water in a hot water tank. Solar energy has been used to provide space and water heating but often meets limitations and inefficiencies in energy transfer in that the temperature of the water in the solar energy collector is not much above ambient temperature. (The laws Thermodynamics state that heat flows from a hot substance to a cooler one in a rate governed by the difference in temperature, hence the higher the temperature difference, the greater the rate of heat transfer attainable.) The invention described herein is a system in which the collector of solar thermal energy is a smooth-surfaced reflector dish, similar in shape to a TV satellite dish, which concentrates the solar energy at a focal point thus giving rise to a temperature that is significantly higher than that with plate or trough or other conventional types of solar energy collectors, and which can thus transfer the solar energy to the circulating medium - water, air or other fluid - with a significant increase in heat transfer capability.

Title: Multi-cavity resonator interferometer
Inventor: TAI KUOCHOU
IPC: G02B6/34
Filed: 2002-05-24
Abstract: Interleavers, based on a Michelson interferometer with a Gires-Tournois (GT) etalon in each arm, are becoming popular in the filtering of light in the fiber optics telecommunications industry. As the channel spacing becomes closer together, e.g. 50GHz or 25GHz, dispersion compensation becomes an important factor in the choice and design of a system. The present invention solves the problem of increased chromatic dispersion by utilizing multi-cavity Gires-Tournois (MCGT) etalons, wherein the dispersion from one MCGT is used to compensate or cancel the dispersion from the other MCGT. In an optimum design for a dual cavity GT etalon, the dispersion profile of the first MCGT will have a similar amplitude and frequency as the dispersion profile of the second MCGT, only shifted by half the period so that the positive slopes of one profile are aligned with the negative slopes of the other profile.
