Abstract: Support structures are used in certain additive fabrication processes to permit fabrication of a greater range of object geometries. For additive fabrication processes with materials that are subsequently sintered into a final part, an interface layer is formed between the object and support in order to inhibit bonding between adjacent surfaces of the support structure and the object during sintering.

Abstract: A patient interface is configured to deliver a flow of pressurized breathable gas to a patient's airways. The patient interface includes a central portion with an opening configured to deliver the pressurized breathable gas to the patient's nares. A first stabilizing portion extends from the central portion and is structured to engage an outer side of a respective one of the patient's nostrils. A second stabilizing portion is opposite the first stabilizing portion and extends from the central portion. In addition, the second stabilizing surface is structured to engage an outer side of a respective one of the patient's nostrils. The central portion, the first stabilizing portion and the second stabilizing portion cooperate to form a U-shape configured to cradle the patient's nose so that the tip of the patient's nose remains exposed when the patient interface is mounted on the patient's face.

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: A depth estimation module may receive a reference image and a set of source images of an environment. The depth module may receive image features of the reference image and the set of source images. The depth module may generate a 4D feature volume that includes the image features and metadata associated with the reference image and set of source images.

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.
