  • Publication number: 20100008005
    Abstract: An apparatus, system, and method are disclosed for preventing reverse current in a switching power supply. An electrical connector receives an input current from an electric source. An input current limiting module substantially prevents the input current from reaching a switching power supply when the input current is flowing in a reverse direction. A voltage reduction module reduces an input voltage of the switching power supply to a switching voltage when the input current is flowing in a forward direction. A switching module closes a switch in response to the voltage reduction module providing the switching voltage. The switch provides the input current a lower impedance path to the switching power supply than does the input current limiting module.

  • Publication number: 20100011234
    Abstract: An apparatus, system, and method is provided for reducing idle power in a power supply. The apparatus includes a connection module to determine whether a load is connected to the output terminal of the power supply. Also included is an idle module that turns off the power supply for an idle interval when the connection module determines that a load is not connected to the output. A monitor module turns on the power supply for a monitor interval when the idle interval ends. During the monitor interval, the connection module determines whether the load has been connected to the output terminal of the power supply. An activation module turns on the power supply if the connection module determines, during the monitor interval, that the load has been connected to the power supply. If the load has not been connected, another idle interval is initiated.

  • Publication number: 20090327268
    Abstract: Systems and methods for providing immediate access to comprehensive information and answers on a set of related search engine results pages for common searches executed in the entertainment domain relating to, for instance, music, musicians, movies and celebrities. Upon receipt of a keyword-based search query, a decision is made regarding what the user actually wanted to see as a search result. This information is then automatically presented in a dedicated region of the keyword search results page, typically with links to more refined information. Upon selection of a link, the refined information is also displayed in a dedicated region of the keyword search results page. In this way, the user does not have to navigate multiple, different user interfaces on a variety of different web sites in order to view the information desired.

  • Publication number: 20090318311
    Abstract: A method of determining common three-dimensional structural features of protein surfaces is provided, as is use of representations of these common structures in molecular database searching and in designing focused molecular libraries. The method is particularly concerned with the analysis and representation of protein surfaces such as b-turns, loops and contact surfaces. In one form, the method identifies common locations and orientations of amino acid side-chains, simplified as C?-C? vectors. In another form, the method identifies common regions of surface charge represented by grid points in three-dimensional space. Further provided are common three dimensional structural features of proteins that can be used to search molecular databases for the purposes of identifying molecules that match these common three dimensional structural features.

  • Publication number: 20090311843
    Abstract: Disclosed is a container capacitor structure and method of constructing it. An etch mask and etch are used to expose portions of an exterior surface of electrode (“bottom electrodes”) of the container capacitor structure. The etch provides a recess between proximal pairs of container capacitor structures, which recess is available for forming additional capacitance. Accordingly, a capacitor dielectric and a top electrode are formed on and adjacent to, respectively, both an interior surface and portions of the exterior surface of the first electrode. Advantageously, surface area common to both the first electrode and second electrodes is increased over using only the interior surface, which provides additional capacitance without a decrease in spacing for clearing portions of the capacitor dielectric and the second electrode away from a contact hole location.

    Abstract: A system and method for providing product research help to a consumer doing internet shopping. A consumer helper application for internet commerce has been designed to integrate the techniques that are currently used by many internet consumers into a single application program. For example, the consumer helper application allows a user to take notes, store web site links, store web site annotations, obtain collaborative input, and perform other tasks commonly used by web site consumers. The consumer helper application stores all of the information gathered in a single place. Information provided by other consumers may be shared using the consumer helper application. The consumer helper application will suggest specific items for a consumer to purchase based up on the information gathered by the consumer into the consumer helper application.

  • Patent number: 7625694
    Abstract: Disclosed herein are techniques for using diblock copolymer (DBCP) films as etch masks to form small dots or holes in integrated circuit layers. In an embodiment, the DBCP film is deposited on the circuit layer to be etched. Then the DCBP film is confined to define an area of interest in the DCBP film in which hexagonal domains will eventually be formed. Such confinement can constitute masking and exposing the DCBP film using photolithographic techniques. Such masking preferably incorporates knowledge of the domain spacing and/or grain size of the to-be-formed domains in the area of interest to ensure that a predictable number and/or orientation of the domains will result in the area of interest, although this is not strictly necessary in all useful embodiments. Domains are then formed in the area of interest in the DBCP film which comprises a hexagonal array of cylindrical domains in a matrix. The film is then treated (e.g.
