Abstract: A method for providing navigation information to a user, the method including: inputting identification associated with the user into one terminal of a plurality of terminals distributed throughout an area visited by the user, each terminal being located in a kiosk and operating in kiosk mode; inputting a destination; computing a route from the kiosk to the destination; and presenting the route as the navigation information to the user.

Abstract: A method and system of position determination using image deformation is provided. One implementation involves storing an actual tag in a reference data module, receiving an image of a visual tag, the image captured by an image capturing device, comparing properties of the visual tag with properties of the actual tag; and based the comparison, determining a position of the image capturing device relative to the visual tag.

Abstract: The present disclosure is directed towards a multimedia system comprising a multimedia reader. The multimedia reader may be configured to read multimedia content and to extract light surround content. The light surround content may represent a light surround control signal. The light surround content may be extracted from the multimedia content. The multimedia reader may also be configured to output the light surround control signal. Further, the multimedia system may also include one or more light emitting devices. Each light emitting device may be in communication with the multimedia reader. Each light emitting device may be configured to receive the light surround control signal and to control a light characteristic based upon, at least in part the light surround control signal. Numerous other embodiments are also within the scope of the present disclosure.

Abstract: A method and system of position determination using image deformation is provided. One implementation involves receiving an image of a visual tag, the image captured by an image capturing device, wherein the visual tag has a predefined position associated therewith; based on the image determining a distance of the image capturing device from the visual tag, and determining an angular position of the image capturing device relative to the visual tag; and determining position of the image capturing device based on said distance and said angular position.

Abstract: The present invention discloses a system and a method for transmitting DTMF signals over high speed digital networks using voice compression algorithms, and particularly to a system for ensuring the integrity of DTMF signals at the destination node of a network after compression and decompression of data on a voice connection. A DTMF Detector is placed in parallel with a voice compression unit performing the compression algorithm. When a candidate DTMF signal is detected, the signal component at the higher frequency in the candidate is filtered out to eliminate the possibility of double DTMF detection at end user equipment. When the candidate DTMF signal is finally validated by the source node as representing a true DTMF signal, only the data essential for reconstituting the DTMF signal are transferred to the destination node.

Abstract: Method and apparatus allows accurate detection of voice presence on a digitized communication line even in the presence of tone signals. The method includes analyzing digitized communication input signals by current blocks of 20ms, to define the stationary or non stationary state of any current block. Then an analysis on the states of the M last 20ms blocks allows the final decision on voice presence.
