Publication number: 20120259695Abstract: In response to a query for information in a geographic region or at a location, ranked ads may be plotted on, or in association with, a map (e.g., as a list beside the map), satellite photo, or any other form of visual representation of geographic information (referred to generally as “maps”). Sponsored ads might be shown in a dedicated place and/or might be elevated above other non-sponsored search results (e.g., Yellow Page listings). The number of ads shown in the list and/or plotted on the map could vary as a function of the resolution of the map or geographic image. The ads could be ranked or scored, and attributes or features of various ads may be a function of such a score or ranking. The plots on the map might be selectable to provide a pop-up with further information and possibly sponsored information (such as images, further ads, etc).Type: ApplicationFiled: June 20, 2012Publication date: October 11, 2012Applicant: GOOGLE INC.Inventors: Steve Glassman, Joshy Joseph, Bill Kilday, Giao Nguyen, Dominic Preuss, Sridhar Ramaswamy

Publication number: 20120116884Abstract: The usefulness, and consequently the performance, of advertisements are improved by allowing businesses to better target their ads to a responsive audience. For example, location information may be used in ad relevancy determination, and in attribute (e.g., position) arbitration. Such location information may be associated with price information, such as a maximum price bid, and/or with ad performance information. Ad performance information may be tracked on the basis of location information. The content of an ad creative, and/or of a landing page may be selected and/or modified using location information. Tools may be provided to enter and/or modify location information, such as location-dependent targeting information and price information. The location information used to target and/or score ads may be, include, or define an area. The area may be defined by at least one geographic reference point (e.g., defined by latitude and longitude coordinates) and perhaps additional information.Type: ApplicationFiled: October 31, 2011Publication date: May 10, 2012Inventors: Leslie Yeh, Sridhar Ramaswamy, Zhe Qian, Mark Rose

Patent number: 7983949Abstract: A system and method for selecting targeted information (e.g., advertisements) for serving with map views. The information is associated with target geographical areas (e.g., cities, metropolises, regions, countries) identified by the information providers. A given message or other set of information may be served with map views that significantly intersect the message's target area. A target area significantly intersects a map view if it overlaps the map view by at least a threshold percentage of the map view (e.g., 25%). Messages' target areas may first be compared with a map view to identify those that significantly intersect. Then, the messages whose target areas significantly intersect the map view may be filtered or screened based on any search terms or key words received with a request for the map view.Type: GrantFiled: April 7, 2006Date of Patent: July 19, 2011Assignee: Google Inc.Inventors: Joshy Joseph, Sridhar Ramaswamy, Mark Rose

Patent number: 7746182Abstract: Various systems, methods and apparatus for calibrating a clock generating circuit are discussed herein. As one example, a method for calibrating a voltage controlled oscillator is disclosed. The method includes fixing the control voltage of a fine tune capacitor in the voltage controlled oscillator at a predetermined level. A binary search is performed in a digital circuit for a value of a calibration word that is used to enable switched capacitors in a coarse tune capacitor bank in the voltage controlled oscillator. The calibration word is fixed at the value determined by the binary search, and the control voltage of the fine tune capacitor is released to enable adjustment of the control voltage by a feedback signal to the voltage controlled oscillator.Type: GrantFiled: May 9, 2008Date of Patent: June 29, 2010Assignee: Texas Instruments IncorporatedInventors: Sridhar Ramaswamy, Mustafa Ulvi Erdogan

Patent number: 7595725Abstract: A system and method for identifying, from a set of geographical areas, a set of target areas that overlap a map view or view port of a map. Target areas are defined as circles having centers and radii, as sets of geographic cells overlaying the areas, or as other polygons of geographic data. Within a view port served or to be served to a user, multiple points are defined and substantially equally spaced within the view port, such that any target area that may significantly overlap the view port (e.g., at least a threshold percentage of the view port) is likely to overlap a minimum number of the points (e.g., one). Some or all target areas are then tested for intersection with some or all of the points, and calculations may be made to determine how much the intersecting areas actually overlap the view port.Type: GrantFiled: April 7, 2006Date of Patent: September 29, 2009Assignee: Google Inc.Inventors: Joshy Joseph, Sridhar Ramaswamy, Mark Rose

Patent number: 7576754Abstract: A system and method for determining bounds of a geographical area, such as a city, metropolis, region (e.g., state) or country. From a set of coordinates within the area (e.g., latitude/longitude coordinates), a grid of relatively small cells of geographic data is overlaid upon those coordinates and associated with the area. Each initial cell is iteratively replaced with a larger cell that encompasses the initial cell until the replacement cell intersects a cell associated with some other geographical area or some other boundary condition is met (e.g., a threshold number of replacements).Type: GrantFiled: April 7, 2006Date of Patent: August 18, 2009Assignee: Google Inc.Inventors: Joshy Joseph, Sridhar Ramaswamy, Mark Rose

Patent number: 7443913Abstract: An equalizer comprises a sampler, a filter, and a summer. The sampler samples a signal indicative of an input communication signal to determine digital decision output signals having a communication device data rate. The filter receives digital decision output signals from the sampler and generates equalization signals therefrom. The summer couples to the sampler and the filter and combines together the input communication signal with the equalization signals. Further, a plurality of clocks control timing associated with the sampler. These clocks have frequencies that are less than the predetermined data rate of the digital decision output signals.Type: GrantFiled: February 12, 2004Date of Patent: October 28, 2008Assignee: Texas Instruments IncorporatedInventors: Bhavesh G.
