Abstract: The present invention relates to a method in a sending device for sending information to a receiving device. The sending device is adapted to emit electromagnetic radiation with different wavelengths. The method comprises sending electromagnetic radiation of a norm wavelength to the receiving device and sending electromagnetic radiation of a second wavelength to the receiving device. The difference between the first wavelength and the second wavelength per time unit represents information to be sent to the receiving device. The present invention also relates to a computer program for performing a method of sending information, a sending device, a method for receiving information, a receiving device and a computer program for performing a method of receiving information.

Abstract: A device is provided that includes a battery, a positive node and a negative node and logic configured to send a first signal through the positive node into a charging surface; send a second signal through the negative node into the charging surface; receive current from the charging surface in response to the first and second signals; and charging the battery with the received current from the charging surface.

Abstract: Disclosed is are a system and a method for accepting user input in the form of movement of an object against a surface of a electronic device. The movement may take the form of natural writing-style stokes that generate corresponding vibrations. The vibrations may be sensed and analyzed to ascertain meaningful user input. In one approach, a method of processing user input with an electronic device includes sensing vibrations generated by movement of an object against a surface of the electronic device and analyzing signals representative of the sensed vibrations to determine a meaningful user input.

Abstract: A system and method for generating a thumbnail image for an audiovisual file. The thumbnail image may be used to convey information about the content of the audiovisual file to a user. With respect to audio files, the information may be the type of audio content, a musical genre, a tempo of the audio content, and one or more indications of the popularity of the audio content.

Abstract: A system receives information associated with locations of multiple people, where the information is derived based on each of the multiple people's use of an electronic device. The system cross-references the locations of the multiple people to locations of one or more places where people get together to determine a number of the multiple people who are located at the one or more places. The system further provides a visual representation of a popularity of each of the one or more places to a user device based on the determined number of the multiple people who are located at the one or more places.

Abstract: A mobile device may capture video of a media signal, parse frames of the captured video, and identify a tag within one or more of the frames of the captured video, where the tag includes a machine-readable representation of information. The mobile device may also analyze the tag to determine the information included in the tag, and present particular information based on the information included in the tag.
