  • Patent number: 8521422
    Abstract: A navigation system written in J2ME MIDP for a client device includes a plurality of media players each respectively comprising a buffer. A navigation program manages the state of the plurality of media players. The plurality of media players are in either one of an acquiring resources state, and a playing and de-allocating state. The use of a plurality of media players each respectively comprising a buffer overcomes the prior art in which navigation system can cut off a voice prompt because of the time-consuming tasks associated with playing a voice prompt.
    Type: Grant

  • Publication number: 20090144247
    Abstract: A persistent point-of-interest search is performed during map panning. A persistent search criteria module identifies a search criteria from a first mapping tile request and stores the search criteria in association with a particular wireless device. A mapping tile module identifies a neighboring mapping tile from a second mapping tile request and performs a point-of-interest search for the neighboring mapping tile with the stored search criteria. In this manner, a user need only enter a search criteria for a point-of-interest once, the point-of-interest being displayed automatically for subsequent map tiles displayed for the user.
