Abstract: A method in a movable device for locating or positioning of the movable device within an environment comprises: receiving, from an external unit, a central environment model; determining distance-dependent measurements for one or more positions of the movable device; determining a location of the movable device based on the received central environment model and the determined distance-dependent measurements, said determining comprising: forming a local environment model defining estimated locations of the wireless transmission sources and of the one or more positions of the movable device, wherein the estimated locations of the wireless transmission sources in the local environment model are updated in relation to the central environment model, wherein the updated estimated locations of the wireless transmission sources and the estimated locations of the one or more positions of the movable device are set based on a calculated error of the local environment model in relation to the determined distance-depend

Abstract: A wireless mobile terminal works with an identification server to automatically identify a broadcast program/movie and then identify and connect to a networked media server to receive the identified program/movie therefrom. The terminal generates data that characterizes content of a broadcast program/movie that is send by the terminal and is playing external thereto. The terminal transmits a message that includes the characterization data and a request for identification of a media server from which the broadcast program/movie can be received. The identification server identifies the broadcast program/movie, and identifies a user viewed location within the identified program/movie that corresponds to what was sensed by the terminal. The identification server identifies an Internet address of a media server from which the terminal can receive transmission of the identified program/movie.

Abstract: An audio playback device and method searches initiates a web search for images related to music or other audio files being played, downloads images from selected web pages returned by the search engine, and outputs one or more images from the selected web pages on a display to enhance the user's listening experience.

Abstract: A battery charger charges a battery in a portable chargeable electronic device, such as a cellular phone, with a long-term-constant current, even while the device is used. The charging current is controlled by circuitry in the portable device, avoiding the need for control circuitry in the battery charger or battery. A battery-charger connector that corresponds to the type of battery in the portable device is keyed to fit only a charger that matches the type of battery, thus assuring proper charging of the battery. Alternatively, a simple contact connects the battery charger to the battery. A belt clip covers the battery-charger connector when the battery charger is disconnected to prevent short-circuiting the battery.
