摘要： Disclosed are methods, techniques and/or systems for selecting and/or determining a strategy and/or approach for searching for signals at a mobile device. Characteristics of and/or information obtained from such searched signals may be used in estimating a location of the mobile device. In one particular example, a strategy and/or approach for searching for wireless signals may be based, at least in part, on an availability of resources at a mobile device.

摘要： Various methods, apparatuses and articles of manufacture are provided for use in or with a mobile device to identify one or more attributes for each of a plurality of positioning resources available at the mobile device. In an example, positioning resources may provide all or part of a position fix based, at least in part, on one or more wireless signals received by the mobile device, and/or one or more electrical signals received from one or more sensors onboard the mobile device. For example, in certain instances at least one of the positioning resources may have at least one attribute that is different than at least one other attribute of another positioning resource. In certain examples, at least one of the positioning resources may be selected for obtaining a position fix based, at least in part, on a request and one or more particular attributes.

摘要： Systems and methods for detecting a vehicle static condition are provided. In this regard, a representative system includes a sensor operative to detect at least one of acceleration and angular rate of a vehicle. The sensor is further operative to generate a vehicle vibration profile based on the at least one of the detected acceleration and angular rate of the vehicle. The system further includes a computing device operative to receive the vehicle vibration profile from the sensor, the computing device being further operative to determine whether the vehicle is stationary or moving based on the vehicle vibration profile. A representative method for detecting a vehicle static condition includes detecting at least one of acceleration and angular grade of a vehicle; generating a vehicle vibration profile based on at least one of the detected acceleration and angular grade of the vehicle; receiving the vehicle vibration profile; and determining whether the vehicle is stationary or moving based on the vehicle vibration profile.
