This problem has been addressed before, but the way of doing so is flawed and incomplete. Only larger objects can be tracked, neglecting items such as glasses, TV remotes, and headphones. Some also solely use Bluetooth tracking, which can be quick and precise, but is unreliable. Items lost far away from people with Bluetooth active their phone cannot be found using this method. This is not an option for most small, easily misplaced items. Various embodiments of the device (in one case using the name SeekR) allow for tracking of all these difficult-to-keep-track-of items. The device's small size allows it to attach to all of these items that existing solutions cannot, e.g., on the frame of glasses, e.g., the bridge, temple and/or temple tips. The device also incorporates assisted global positioning system (AGPS), which is much more reliable than tracking devices that solely use Bluetooth technology, and, in many cases, using AGPS results in identifying the location of a lost item faster than using Bluetooth (or other short distance wireless communication systems). The AGPS system used in various embodiments combines trilateration and global positioning system (GPS) technology to determine a more accurate device location in less time than using GPS systems alone.

Systems and methods for determining a location of a mobile computing device requesting emergency services are provided. A mobile computing device may receive an indication of a request for emergency services from a user of the mobile computing device. The mobile computing device may receive a first wireless signal from a first device. The wireless signal may include an indication of a first geographic position associated with the first device. The mobile computing device may determine a location associated with the mobile computing device based on the indication of the first geographic position associated with the first device, and may send the determined location to a provider of emergency services.

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine its position by receiving locations from one or more other UEs capable of network-based positioning. For example, a second UE may determine its location using network-based positioning and may transmit its location information to the first UE. The first UE may determine its location based on the received location information (e.g., by calculating a weighted average of different locations, by setting its location to be the same as the received location). In some cases, the first UE may receive location information from other UEs during or after a discovery process with other UEs. In some other cases, the first UE may receive messages (e.g., periodic safety messages) from the other UEs, and the messages may each include location information of the respective other UEs.

A method and system for validating the calculated localization (15) of a vehicle are devised. The vehicle (1) is equipped with P independent localization data sources (2-8), with P higher than or equal to 2. The method and system involve the step of comparing data provided by each one of a subset of M, with M lower than or equal to P, of the independent localization data sources with the calculated localization, by correlating an independent localization data source among the subset M if it is above a predetermined Reliability Threshold, and the distance between the data it provides and the calculated localization is lower than a predetermined Compatibility Threshold, and disregarding an independent localization data source among the subset M if either it is below the predetermined Reliability Threshold, or the distance between the data it provides and the calculated localization is higher than the predetermined Compatibility Threshold, and the step of modifying the speed of the vehicle (1) depending on the number of correlated independent localization data sources among the subset M relative to a predetermined Voting Threshold.
