    • A number of devices co-located at a geographic location can broadcast and receive tokens. Tokens can be exchanged using a communication link having limited communication range. Tokens that are received by a device can be stored locally on the device and/or transmitted to a trusted service operating remotely on a network. In some implementations, the tokens can be stored with corresponding timestamps to assist a trusted service in matching or otherwise correlating the tokens with other tokens provided by other devices. The trusted service can perform an analysis on the tokens and timestamps to identify devices that were co-located at the geographic location at or around a contact time which can be defined by the timestamps. A group can be created based on results of the analysis. Users can be identified as members of the group and invited to join the group.
    • 位于地理位置的多个设备可以广播和接收令牌。 可以使用具有有限通信范围的通信链路来交换令牌。 由设备接收的令牌可以本地存储在设备上和/或被发送到在网络上远程操作的受信任的服务。 在一些实现中,令牌可以以对应的时间戳存储,以协助可信服务以匹配或以其他方式将令牌与由其他设备提供的其他令牌相关联。 信任的服务可以对令牌和时间戳进行分析,以识别在时间戳可以定义的联系时间周围或周围地理位置处共处的设备。 可以根据分析结果创建一个组。 用户可以被识别为该组的成员,并被邀请加入该组。

    • A parameter related to the Earth's magnetic field can be used to determine accuracy of a magnetometer of a mobile device. In one aspect, a first instance of a parameter related to Earth's magnetic field is determined using data generated by the magnetometer. The magnetometer data can be based in part on a position of the mobile device with respect to the Earth. A second instance of the parameter can be determined using data generated by a model of Earth's magnetic field. The model data can also be based in part on the position of the mobile device with respect to the Earth. The first instance of the parameter can be compared with the second instance of the parameter. An accuracy metric for the magnetometer can be determined based on a result of the comparison. An indication of the accuracy metric can be presented by the mobile device.

    • A mobile device establishes communication with a number of wireless cellular networks at particular locations and records the locations and network information associated with the wireless cellular networks. The network information can be used to narrow a search for an available wireless cellular network from a plurality of potentially available wireless cellular networks when the mobile device is operating at a stored location. In one aspect, a Radio Frequency (RF) receiver on a mobile device can receive a broadcast radio signal from a transmitter and use the signal to determine an approximate location of the device based on a known location of the transmitter. A match between the approximate device location and wireless cellular network transmitters in communication range of the mobile device can be used to narrow a search for wireless cellular networks.
    • 移动设备与特定位置处的多个无线蜂窝网络建立通信,并且记录与无线蜂窝网络相关联的位置和网络信息。 当移动设备在存储的位置操作时,网络信息可以用于缩小从多个潜在可用的无线蜂窝网络中搜索可用的无线蜂窝网络。 在一个方面,移动设备上的射频(RF)接收机可以从发射机接收广播无线电信号,并使用该信号基于发射机的已知位置来确定设备的大致位置。 可以使用移动设备的通信范围内的近似设备位置与无线蜂窝网络发射机之间的匹配来缩小对无线蜂窝网络的搜索。

    • An interactive game environment includes two or more co-located, networked, direction and location aware interactive game devices. The game devices share a common reference coordinate frame (e.g., a three-dimensional Cartesian coordinate frame). Each game device maintains its own device state (e.g., position, orientation, time) in the reference coordinate frame. Each interactive game device shares its device state with the other interactive game devices using communication technology (e.g., Bluetooth, Wi-Fi, cellular). Each interactive game device can use the device states of the other interactive game devices to project the relative positions and orientations of the other interactive game devices into a local, fixed coordinate frame of the interactive game device. These projections allow each interactive gaming device to know the position and orientation of the other interactive game devices in an interactive game environment defined by the reference coordinate frame.
    • 交互式游戏环境包括两个或多个共同位置,联网,方向和位置感知交互式游戏设备。 游戏装置共享公共参考坐标系(例如,三维笛卡尔坐标系)。 每个游戏装置在参考坐标系中保持其自己的装置状态(例如,位置,方位,时间)。 每个交互式游戏设备与使用通信技术(例如,蓝牙,Wi-Fi,蜂窝)的其他交互式游戏设备共享其设备状态。 每个交互式游戏设备可以使用其他交互式游戏设备的设备状态来将其他交互式游戏设备的相对位置和方向投影到交互式游戏设备的本地固定坐标系中。 这些投影允许每个交互式游戏设备在由参考坐标系定义的交互式游戏环境中知道其他交互式游戏设备的位置和方位。

    • A location aware mobile device can include a baseband processor for communicating with one or more communication networks, such as a cellular network or WiFi network. In some implementations, the baseband processor can collect network information (e.g., transmitter IDs) over time. Upon request by a user or application, the network information can be translated to estimated position coordinates (e.g., latitude, longitude, altitude) of the location aware device for display on a map view or for other purposes. A user or application can query the location history database with a timestamp or other query to retrieve all or part of the location history for display in a map view.
    • 位置感知移动设备可以包括用于与诸如蜂窝网络或WiFi网络的一个或多个通信网络进行通信的基带处理器。 在一些实现中,基带处理器可以随着时间收集网络信息(例如,发射机ID)。 根据用户或应用的请求,网络信息可以被转换为位置感知设备的估计位置坐标(例如,纬度,经度,高度),以便在地图视图上显示或用于其他目的。 用户或应用程序可以使用时间戳或其他查询查询位置历史记录数据库,以检索全部或部分位置历史记录,以便在地图视图中显示。
