Patent number: 8095336Abstract: The invention is related to methods and apparatus that use a visual sensor and dead reckoning sensors to process Simultaneous Localization and Mapping (SLAM). These techniques can be used in robot navigation. Such visual techniques can be used to autonomously generate and update a map. Unlike with laser rangefinders, the visual techniques are practical in a wide range of applications and can be used in relatively dynamic environments, such as environments in which people move. One embodiment further uses multiple particles to maintain multiple hypotheses with respect to localization and mapping. One embodiment maintains the particles, thereby permitting the SLAM processes to be performed in software using microprocessor-based computer systems.Type: GrantFiled: July 20, 2010Date of Patent: January 10, 2012Assignee: Evolution Robotics, Inc.Inventors: Luis Filipe Domingues Goncalves, Enrico Di Bernardo, Paolo Pirjanian, L.

Publication number: 20110112893Abstract: In accordance with the invention, a system, method, and apparatus for analyzing advertisement-related data are presented, which may include receiving data related to an aspect of an advertisement and modeling the aspect of the advertisement with a mathematical model. The mathematical model may include a control-signal-related component, a control-signal-independent component, and an error component. Each component may be updated based on at least one of a control signal, the received data, and a previous state of at least one of the components. An updated model may be created based on the updated components. The system, method, and apparatus may also include predicting the aspect of the advertisement using the updated model. Exemplary aspects of and data related to the advertisement may include one or more of the following: a number of impressions, “clicks,” or “conversions” and/or the impression-to-conversion, impression-to-click, or click-to-conversion ratios.Type: ApplicationFiled: October 5, 2010Publication date: May 12, 2011Inventors: Niklas Karlsson, Jianlong Zhang, Jaime Batiz-Mendoza

Patent number: 7835938Abstract: A system, apparatus, and method are presented for shaping a reference signal from an advertising campaign that allocates advertisements in digital or online advertising. The method includes receiving a reference signal; providing parameters representing a volume of revenue generating events resulting from the advertising campaign; shaping the received reference signal to adjust for variations in the volume of revenue generating events; and using the shaped reference signal to determine a control signal to control the allocation of advertisements.Type: GrantFiled: October 31, 2007Date of Patent: November 16, 2010Assignee: AOL Advertising Inc.Inventor: Niklas Karlsson

Patent number: 7835937Abstract: Methods and systems consistent with the present invention enable the control of aspects of an advertising campaign, such as revenue expenditure, by comparing actual and desired behavior and incorporating feedback and feed-forward error correction to continuously adjust the campaign's behavior. In certain embodiments, this control is achieved without considering individual advertisement requests or ad placements, thus bypassing the lowest-level details and instead adjusting behavior on a campaign-wide level using an adaptive control system.Type: GrantFiled: October 15, 2007Date of Patent: November 16, 2010Assignee: AOL Advertising Inc.Inventors: Niklas Karlsson, Jianlong Zhang, Yonggang Xu

Patent number: 7835939Abstract: Methods and system are provided to predict data related to advertising. Predicted data may include impressions, clicks, actions, or other data related to the advertisement, such as the ratio of impressions to clicks or the ratio of clicks to actions. Methods for predicting revenue of an advertising campaign use a revenue predictor in a campaign control computer while the campaign is ongoing. Based on a starting point in time during the advertising campaign when a starting revenue and volume data through the starting point in time were known and a target point in time, a cumulative predicted revenue can be determined. Based on an estimated revenue generated by the advertising campaign from a time just after the starting point in time until a selected point in time and a predicted revenue from a time just after the selected point in time until the target point in time is computed, the cumulative predicted revenue for the advertising campaign through the target point in time is determined.Type: GrantFiled: October 31, 2007Date of Patent: November 16, 2010Assignee: AOL Advertising Inc.Inventor: Niklas Karlsson
