Abstract: The present disclosure relates to systems and methods to generate user or user group behavior similarities based on computing distances between individual users or user groups and without using demographic data, e.g., based on anonymized data. The methods include creating a multidimensional vector representation for each user in a group by summarizing user's behaviors across various categories. Based on the created vectors, distance calculation and nearest neighbor search are performed to locate users that are most similar to target users. The resulting distance metrics may be used to rank similarities. Additionally, dimensionality reduction may be performed to further distill the behavior information to make the disclosed methods suitable for a variety of analytics and modeling tasks.

Abstract: Household appliances may include partially reflective (e.g., one-way mirror) glass as part of an oven door. The partially reflective glass may transmit light from an interior of the household appliance and may reflect light from outside the household appliance. Accordingly, one can see into the lighted interior but a camera inside the interior cannot see out through the door. In some examples, the household appliance includes a lamp and a camera disposed within the cavity of the appliance. The lamp and the camera are interlocked to protect user privacy by activating the one-way feature of the door glass as needed.

Abstract: A method and apparatus for monitoring a human or animal subject in a room using video imaging of the subject and analysis of the video image to derive an estimate of vital signs such as heart rate or breathing rate. The method includes determination of whether the subject in the images is still or moving, and whether any of the regions from which vital signs are being detected are not on the subject. The subject's movement may be manually or automatically detected, and the determination of whether regions from which vital signs are being detected are not on the subject can be input manually, by displaying the regions to the user in a visually distinguishable manner, or automatically. Vital signs measurements are only displayed if the subject is determined as being still and if there are no regions in the image which are returning vital signs signals but are not determined as being on the subject.
