Abstract:
An electronic device may include a pressure sensor for measuring barometric pressure. Pressure measurements may be calibrated using crowd-sourced pressure data to remove any weather bias or sensor bias associated with the pressure measurements. Altitude of the electronic device may be determined using the calibrated pressure measurement. When it is desired to estimate altitude, the electronic device may transmit a query to a server, which returns a local reference pressure value for the electronic device based on crowd-sourced pressure data from electronic devices in the vicinity of the electronic device making the query. To determine the local reference pressure value, the server may correlate the crowd-sourced pressure data with space, taking into account variations in terrain using digital elevation models to determine location-specific reference pressures. The local reference pressure value for a given electronic device is then determined using crowd-sourced reference pressures at nearby locations.
Abstract:
An automated environment can include an accessory device that operates according to an automation rule, to take a prescribed action when a triggering condition occurs. A controller device for the automated environment can determine a user's regular routine and can detect when the user is deviating from the regular routine. The controller device can communicate with accessory devices in the automated environment to modify their behavior relative to the automation rules.
Abstract:
Embodiments described herein provide for system and methods to crowdsource the location of wireless devices and accessories that lack a connection to a wide area network. One embodiment provides for a data processing system configured to perform operations comprising loading a user interface on an electronic device, the user interface to enable the determination of a location of a wireless accessory that is associated with the electronic device, generating a set of public keys included within a signal broadcast by the wireless accessory, the signal broadcast during a first period, sending the set of public keys to a server with a request to return data that corresponds with a public key in the set of public keys, decrypting the location data using a private key associated with the public key, and processing the location data to determine a probable location for the wireless accessory.
Abstract:
The presence of a wireless device and/or accessory that cannot maintain an independent network connection can be detected by network connected wireless devices and the location of the detected device and/or accessory can be reported to a device location service. As the wireless devices and/or accessories do not have independent network connections, periodic maintenance is performed on those devices by nearby owner devices to which the wireless devices and/or accessories are paired or associated. Described herein are systems, methods, and associated devices to maintain a locatable wireless device by a set of multiple owner devices for that wireless device.

Abstract:
Described herein are techniques to enable a mobile device to determine a Z-axis coordinate based on altitudes associated with Wi-Fi access points detected in a Wi-Fi scan by the mobile device. One embodiment provides for an electronic device configured to compute a weighted average of Z-axis coordinates associated with detected Wi-Fi access points and determine a Z-axis coordinate for the electronic device based on the weighted average.

Abstract:
A device implementing a system for estimating device location includes at least one processor configured to receive a first estimated position of the device at a first time. The at least one processor is further configured to capture, using an image sensor of the device, images during a time period defined by the first time and a second time, and determine, based on the images, a second estimated position of the device, the second estimated position being relative to the first estimated position. The at least one processor is further configured to receive a third estimated position of the device at the second time, and estimate a location of the device based on the second estimated position and the third estimated position.
