The various implementations described herein include methods, devices, and systems for determining locations of an electronic device. In one aspect, a method is performed at a computing system having one or more processors and memory. The method includes obtaining device identification information for the electronic device; broadcasting a request based on the device identification information that the electronic device be enabled to transmit or reflect location information using a radar technique; receiving a signal from the electronic device, the signal indicating a location of the electronic device using a radar technique; and determining the location of the electronic device based on the received signal.

Systems, methods, and devices for utilizing radar with smart devices

A server system obtains a first video sub-stream comprising a first plurality of images of a scene and obtains a second video sub-stream comprising a second plurality of images of at least a portion of the scene. Images of the second video sub-stream have a higher image resolution or are received at a higher frame rate than images of the first video sub-stream. The first video sub-stream is transmitted to a client device for display. A selection of a region of interest in the scene is received. The server systems locates image data of the selected region of interest from the second plurality of images, and provides the located image data of the selected region of interest to the client device for display.

Systems and methods for locating image data for selected regions of interest

Techniques for adjusting operation of an electronic device are described. In an example, while the electronic device is operating in a first operating mode according to a first parameter, a set of signals indicating an object in a room, and based on received reflected radar signals, are transmitted by a radar transceiver of the electronic device to one or more processors of the electronic device. By analyzing the set of signals to identify the object as a person, the one or more processors determine that the room is occupied. In accordance with determining that the room is occupied by the person, the electronic device is adjusted to operate in a second operating mode according to a second parameter suitable for sensing objects at a closer distance than the first parameter.

Techniques for adjusting operation of an electronic device

An electronic device is located in a room. The device has a casing, a first processor coupled to a radar transceiver, a second processor coupled to a motion sensor, and memory. Using the second processor, the device determines using signals from the motion sensor whether an object is in proximity. In accordance with a determination that the object is in proximity, the device wakes up the first processor. Using the first processor, the device enables operation of the radar transceiver. It determines using signals from the radar transceiver whether the object is in contact with the casing. In accordance with a determination that the object is in contact with the casing, the device identifies an input command based on at least one of: a location of the object, and a movement of the object, and adjusts operation based on the input command.

Systems, methods, and devices for utilizing radar-based touch interfaces

This application discloses a method of provisioning an electronic device. The electronic device establishes a communication link with a client device that can obtain network credentials for accessing a secure wireless network. The network credentials is configured to enable the electronic device to independently access the secure wireless network. The client device encrypts at least a portion of the network credentials using a password key provided by a remote server. The password key is based on a secret not known to the client device, and the secret is associated with the electronic device at the remote server. The client device sends the encrypted network credentials to the electronic device over the established communication link, thereby allowing the electronic device to recover the network credentials based on the secret and access the secure wireless network using the network credentials.
