Abstract: A method includes detecting, with a passive infrared sensor (PIR), a level of infrared radiation in a field of view (FOV) of the PIR, generating a signal based on detected levels over a period of time, the signal having values that exhibit a change in the detected levels, extracting a local feature from a sample of the signal, wherein the local feature indicates a probability that a human in the FOV caused the change in the detected levels, extracting a global feature from the sample of the signal, wherein the global feature indicates a probability that an environmental radiation source caused the change in the detected levels, determining a score based on the local feature and the global feature, and determining that a human motion has been detected in the FOV based on the score.

Abstract: A method for optimizing the placement of smart-home devices may include receiving, by a mobile computing device, a location for a smart-home device, where the mobile computing device comprises a display and a camera; rendering a view of a virtual object that represents a field-of-view of the smart-home device, where the view of the virtual object is rendered based on a position corresponding to a position of the mobile computing device; and displaying, by the mobile computing device, the view of a virtual object that represents a field-of-view of the smart-home device on the display of the mobile computing device.

Abstract: A camera system includes non-volatile memory, a lens, an image sensor to capture images of a scene within view of the lens, an IR illuminator, and a processing system. The processing system transitions the camera system from day mode to night mode when the scene is dark, and in the night mode, two operations are performed. The first operation uses the IR illuminator, the image sensor, and the memory to capture a first IR image or video of the scene and store the first IR image or video in the non-volatile memory. The second operation uses the IR illuminator, the image sensor, and the memory to identify a specular surface in the scene. This includes capturing a second IR image or video, identifying a first region of low intensity pixels, and storing, in the non-volatile memory, position parameters of the first region and designating the first region as specular.

Abstract: A camera system includes memory, image sensors, illuminators, and a processor. The processor operates the illuminators and the image sensors in a first mode to capture a two-dimensional image of the scene using light transmitted by the illuminators and reflected from the scene. The processor operates in a second mode to capture a plurality of images of the scene, including capturing a first image of the scene while one or more of the illuminators are activated and capturing a second image of the scene is while none of the illuminators are activated. The images are transmitted to a remote cloud computing system. The remote system constructs a light intensity map for the scene using the first and second images, and identifies a first region in the light intensity map as a glass surface when the light intensity values for the first region are below a threshold value corresponding to glass.

Abstract: A method generates depth maps at a camera having illuminators, a lens assembly, an image sensing element, a processor, and memory. The illuminators operate in a first mode to provide illumination, the lens assembly focuses incident light on the image sensing element, the memory stores image data from the image sensing element, and the processor executes programs to control operation of the camera. The method reconfigures the illuminators to operate in a second mode, where each of a plurality of subsets of the illuminators provides illumination of a scene separately. For each subset, the process activates the illuminators in the subset without activating illuminators not in the subset and receives reflected illumination from the scene incident on the lens assembly and focused onto the image sensing element. The measured light intensity of the received reflected illumination at the image sensing element is stored in association with activation of the subset.

Abstract: An example method is provided. Unverified interaction data descriptive of interactions of a user with the computing device can be obtained. Feature values that embed characteristics of the unverified interaction data can be generated using a machine-learned embedding network of a machine-learned verification pipeline. A user account associated with the unverified interaction data can be determined using a verification model of the machine-learned verification pipeline.

Abstract: A head-mounted display device may initiate display of a user interface on a display of the head-mounted display device. A head-mounted display device may compute an angular distance between a previous head orientation and a current head orientation based on head movement data. A head-mounted display device may apply a gain value to the angular distance to move a position indicator to an updated position within a boundary of the user interface, the user interface configured to remain fixed to a location in the display regardless of head movements.
