Abstract: Among other things, one or more techniques and/or systems are provided for locating a position within an enclosure. In one example, known global coordinates (e.g., GPS coordinates of latitude/longitude) associated with the position within the enclosure may be transformed into local coordinates (e.g., x/y coordinates) for the position. The local coordinates may be used for tracking a location of the position within the enclosure. In another example, known local coordinates of the position within the enclosure may be transformed into global coordinates for the position, which may be used for tracking a location of the position within the enclosure. In another example, a blueprint image of the enclosure may be used to track a location of the position within the enclosure. In this way, location tracking may be provided for objects within indoor spaces (e.g., a mapping application may track a current position of a mobile device within a building).

Abstract: A mesh network is initiated by using multiple frequency bands for establishing communication between mesh nodes. In one aspect, a higher or lower frequency communication link may be established depending on the range between two mesh nodes. As the mesh network increases and decreases in density, and range and communication aspects change, a communication link may be change between the higher and lower frequency bands as necessary.

Abstract: Infrastructure services such as addressing, directory services, performance monitoring, and diagnostic capabilities are shared among nodes of an ad-hoc mesh network without a designated network manager. A first mesh node creates parameters corresponding to the services to be provided. As each new mesh node joins the network, parameters are update, synchronized among the mesh nodes, and stored in a virtual database shared by the mesh nodes. For some of the services such as performance monitoring, a designated representative may be elected by a group of mesh nodes once a predetermined number of connected mesh nodes is exceeded. The representative nodes may share performance monitoring information among themselves and act as redundant back-up servers.

Abstract: Methods, systems, and computer program products for using a mobile device to compose an electronic message by adding audio content to the message. Mobile devices include any type of portable or hand-held computing device, such as wireless telephones, personal digital assistants, and the like. After selecting the option to add audio content, the user speaks into the mobile device's audio input. The mobile device diverts the resulting audio stream into a temporary storage as the user speaks. To provide visual feedback, a progress indicator shows the user the amount of audio content stored compared to the amount that may be stored. An indicator shows that a message includes audio content as well as the size of the included audio content. No particular format or type is required for the audio content or electronic message.
