Systems And Methods For Spreading Online Advertising Campaigns

View page
US Patent:
20100262455, Oct 14, 2010
Filed:
Apr 10, 2009
Appl. No.:
12/385553
Inventors:
Niklas Karlsson - Mountain View CA, US
Yonggang Xu - Mountain View CA, US
International Classification:
G06Q 30/00
US Classification:
705 10, 705 26, 705 1453
Abstract:
A system is provided for managing the delivery of online advertisements across inventory units of an online advertising campaign. The system includes a sensor configured to detect current ad volume for an inventory unit of the online advertising campaign. The system also includes a campaign controller configured to generate a reference ad volume for the inventory unit, based on instructions and the detected ad volume; and a unit actuator configured to generate updated ad delivery control settings for the inventory unit, based on the reference ad volume and the detected ad volume. The system also includes a serving unit configured to serve an ad impression on the inventory unit based on the updated ad delivery control settings, wherein the reference ad volume is generated based on a proportion of ad volume served on the inventory unit compared to other inventory units of the online advertising campaign.

Methods For Controlling An Advertising Campaign

View page
US Patent:
7835937, Nov 16, 2010
Filed:
Oct 15, 2007
Appl. No.:
11/907587
Inventors:
Niklas Karlsson - Mountain View CA, US
Jianlong Zhang - Mountain View CA, US
Yonggang Xu - Mountain View CA, US
Assignee:
AOL Advertising Inc. - Baltimore MD
International Classification:
G06F 17/00
US Classification:
705 10
Abstract:
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.

Method And Device For Generating Driving Suggestion, And Computer-Readable Storage Medium

View page
US Patent:
20220392339, Dec 8, 2022
Filed:
Jun 2, 2021
Appl. No.:
17/336646
Inventors:
- Guangzhou, CN
WENQI YANG - GUANGZHOU, CN
RONGBIN LIN - GUANGZHOU, CN
YONGGANG XU - LOS GATOS CA, US
International Classification:
G08G 1/0962
Abstract:
The disclosure provides a method and device for generating driving suggestion, and computer-readable storage medium. The method comprises: acquiring N driving records, wherein the N driving records are derived from at least two vehicles, each driving record comprises a mapping relationship between a driving period and an acceleration value, and the N is an integer greater than 1; determining a plurality of acceleration metric values based on the acceleration values in the N driving records, wherein each vehicle corresponds to at least one acceleration metric value, and the acceleration metric value is positively correlated with the acceleration value; determining a metric threshold according to the plurality of acceleration metric values; and generating a driving suggestion based on the metric threshold and the driving record corresponding to any one of the at least two vehicles.

Method And System For Detecting Vehicle Battery Cell Imbalance

View page
US Patent:
20220381848, Dec 1, 2022
Filed:
Jun 1, 2021
Appl. No.:
17/335604
Inventors:
- GUANGZHOU, CN
YIZHEN ZHANG - SAN JOSE CA, US
YONGGANG XU - LOS GATOS CA, US
International Classification:
G01R 31/396
G01R 31/367
G01R 31/3835
G06N 20/20
H01M 10/42
H01M 10/48
Abstract:
A method and a system for detecting vehicle battery cell imbalance are provided. The method includes: acquiring a plurality of raw vehicle data of a target vehicle type in a preset time period; grouping the plurality of raw vehicle data into a predefined number of bins based on the data type and the value range of raw vehicle data; determining an observed bin-level cell voltage imbalance of the bin based on the raw vehicle data in each bin; building machine learning model to predict bin-level cell voltage imbalance of each bin, based on bin parameters defined; determining a difference between observed bin-level cell voltage imbalance and predicted bin-level cell voltage imbalance of each bin, to obtain an unaccounted bin-level cell voltage imbalance; and determining whether there is a high risk of cell imbalance in a target vehicle based on a weighted average of unaccounted bin-level cell voltage imbalances.

Electronic Device And Method For Scoring Driving Behavior Using Vehicle Inputs And Outputs

View page
US Patent:
20220374745, Nov 24, 2022
Filed:
May 18, 2021
Appl. No.:
17/323327
Inventors:
- Guangzhou, CN
Yiwen GUO - Sunnyvale CA, US
Wenqi YANG - Guangzhou, CN
Yonggang XU - Los Gatos CA, US
International Classification:
G06N 7/00
Abstract:
A method for scoring driving behavior using vehicle inputs and outputs is implemented in an electronic device. The method includes obtaining historical input data and output data of a vehicle; establishing an output regression model according to the historical output data; determining a boundary of the output regression model; establishing an input regression model according to the historical input data; determining a boundary of the input regression model by calculating boundary limits of the input regression model; obtaining real-time input data and output data of the vehicle; calculating a first ratio of data points outside the boundary of the input regression model to total data points in the real-time input data, and a second ratio of data points outside the boundary of the output regression model to total data points in the real-time output data; scoring driving behavior of a driver according to the first ratio and the second ratio.
