International Classification:

H04L 29/08

Abstract:

A geolocation extraction and propagation system for assigning a geolocation to a new user of a website is disclosed herein. An implementation of the geolocation extraction and propagation system assigns a geolocation to a website based on content of various web pages of the website as well as geolocations assigned to various users associated with the website. The geolocation extraction and propagation system further propagates the geolocation of the website to the new user by assigning the geolocation of the website to the new user in response to the new user's click on a web page of the website.

G06N 3/04
H04L 12/58
H04W 4/029

Abstract:

Described herein are technologies related to generating a predicted routine of a user of a mobile computing device. Location entries generated by the mobile computing device are processed to generate visit entries, wherein the visit entries are representative of visits made by the user to places over several days. An input sequence of states is constructed based upon the visit entries, wherein each state has a place identifier assigned thereto, and further wherein each state corresponds to a time interval of predefined length. A predicted routine of the user is generated based upon the input sequence of states.

International Classification:

G06F 17/30

Abstract:

Architecture that enables the creation and utilization of a user location profile for a personalized search experience in recommendation systems. The user location profile does not necessitate login of the user to obtain user profile information such as a user ID. Rather, the identifying information associated with the user location can be a network address and/or a device identifier that identifies the particular device from which the user is performing a search or which auto-suggest is being initiated. The user location profile can then be used to identify items about which the user may want information. Once generated, a matching operation is performed between the user location profile and item profiles in a log. The matched item profiles related to the user's location information (the user physical location and/or or user interested location(s)) are identified and recommended to the user.

International Classification:

G01N 21/47
G06T 7/00

Abstract:

An active illumination range camera that acquires a range and a picture image of a scene and provides a reflectance for a feature in the scene responsive to a distance for the feature provided by the range image, a registered irradiance for the feature provided by the picture image and registered irradiance for a region of a calibration surface corresponding to the feature provided by an image of the calibration surface acquired by the range camera.

A61B 5/00
A61B 5/0255
A61B 5/026

Abstract:

Aspects described herein include a computer-implemented method for detecting heart rate signals. The method includes a step of capturing a first image and a second image of a region of interest. The second image is aligned with the first image in a first spectrum that is insensitive to a characteristic to obtain a correction. Then, a correction based upon the above-mentioned alignment is applied to the second image in a second spectrum that is sensitive to the characteristic. Additional aspects described an image capturing device and a computer-implemented method for updating a user-interactive activity.

International Classification:

G06T 5/50
G06T 5/00
G06T 11/00

Abstract:

Changes in image exposure setting may be compensated by creating a table of aggregate differences between corresponding pixels in two images and applying the table of aggregate differences to a portion of one of the two images. The images may be in any color space for visible light, or images not of visible light, such as infrared or depth images. In various configurations, the differences may be aggregated by averaging the differences for pixels of a certain value in one of the two images.
