  • Patent number: 8522569
    Abstract: A method and system of utilizing waste heat from a plurality of data center equipment comprising the steps of collecting waste heat from a plurality of data center equipment and utilizing said waste heat as the driving heat input for a heat driven engine. Heat recovery means collects waste heat from heat-producing equipment and transfers it in the form of hot water to drive a heat driven engine such as a chiller or heat pump. The output of the heat driven engine may be put to many productive uses, thereby reducing the over all energy load on the data center.

  • Publication number: 20080054728
    Abstract: In general, the present disclosure pertains to systems and methods for providing electrical power from an alternating current (AC) power source to direct current (DC) components. A power supply system in accordance with one exemplary embodiment of the present disclosure has a power supply element and a load controller, and the power supply element receives an AC signal from an AC power source. In this regard, the power supply element is directly connected to the hot wire carrying an AC signal from the AC power source. For each half cycle of the AC signal, the power supply element uses the AC signal to charge a capacitor during a small portion of the half cycle. During another portion of the same half cycle, the load controller may use the AC signal to power an AC load. During the cycle, the capacitor is discharged thereby providing DC power to various components in the system.

  • Patent number: 7132123
    Abstract: The present invention provides a gas discharge laser having at least one long-life elongated electrode for producing at least 12 billion high voltage electric discharges in a fluorine containing laser gas. In a preferred embodiment at least one of the electrodes is comprised of a first material having a relatively low anode erosion rate and a second anode material having a relatively higher anode erosion rate. The first anode material is positioned at a desired anode discharge region of the electrode. The second anode material is located adjacent to the first anode material along at least two long sides of the first material. During operation of the laser erosion occurs on both materials but the higher erosion rate of the second material assures that any tendency of the discharge to spread onto the second material will quickly erode away the second material enough to stop the spread of the discharge.

  • Patent number: 6914927
    Abstract: Methods and apparatus are provided for cleaning and passivating laser discharge chambers with plasmas. In one embodiment, an oxygen based plasma is formed in a plasma source external to the laser discharge chamber by applying a radiofrequency signal to oxygen containing gases. The oxygen based plasma is drawn into the laser discharge chamber, where it reacts with contaminants and cleans internal surfaces. After cleaning, a fluorine based plasma is formed in the plasma source and drawn into the laser discharge chamber to passivate internal surfaces. In another embodiment, cleaning with the oxygen based plasma is not used since some level of cleaning is accomplished with the fluorine based plasma. In another embodiment, oxygen based plasmas and fluorine based plasmas are formed in the laser discharge chamber by applying a radiofrequency signal to a laser discharge chamber electrode.

  • Patent number: 6914919
    Abstract: The present invention provides gas discharge laser systems capable of reliable long-term operation in a production line capacity at repetition rates in the range of 6,000 to 10,0000 pulses power second. Preferred embodiments are configured as KrF, ArF and F2 lasers used for light sources for integrated circuit lithography. Improvements include a modified high voltage power supply capable for charging an initial capacitor of a magnetic compression pulse power system to precise target voltages 6,000 to 10,0000 times per second and a feedback control for monitoring pulse energy and determining the target voltages on a pulse-by-pulse basis. Several techniques are disclosed for removing discharge created debris from the discharge region between the laser electrodes during the intervals between discharges. In one embodiment the width of the discharge region is reduced from about 3 mm to about 1 mm so that a gas circulation system designed for 4,000 Hz operation could be utilized for 10,000 Hz operation.
