Title: Method and system for communicating and exchanging data between browser frames
Inventor: SUBRAMANIAM TARUVAI N
IPC: G06F15/173
Filed: 2005-08-23
Granted: 2012-04-17
Abstract: Browser frames residing on different domain servers may exchange information indirectly without compromising security that ordinary restricts frame to frame communication. The first browser frame causes the browser to generate a notification of a change of state of the browser frame. The browser sends the notification, together with data values from the content of the first browser frame, to a domain server that hosts the second frame. The server software running on the domain server receives and interprets the notification and data values, and updates the content of the second frame according to the interpretation. The domain server then sends the updated content back to the browser that issued the notification. The browser displays the updated content in the area allocated to the second frame.

Abstract: At an audio encoder, cue codes are generated for one or more audio channels, wherein a combined cue code (e.g., a combined inter-channel correlation (ICC) code) is generated by combining two or more estimated cue codes, each estimated cue code estimated from a group of two or more channels. At an audio decoder, E transmitted audio channel(s) are decoded to generate C playback audio channels. Received cue codes include a combined cue code (e.g., a combined ICC code). One or more transmitted channel(s) are upmixed to generate one or more upmixed channels. One or more playback channels are synthesized by applying the cue codes to the one or more upmixed channels, wherein two or more derived cue codes are derived from the combined cue code, and each derived cue code is applied to generate two or more synthesized channels.

Abstract: A method and system of updating location information of a portable computing device is disclosed. Location data is received from a positioning device. A voice link is utilized for communication between the portable computing device and a call center. A dual-tone multi-frequency signal is mapped to a pre-determined range of movement. The dual-tone multi- frequency signal is transmitted to the call center when a longitude and/or latitude measurement in the location data indicates a change in longitude that is within the pre-determined rage of movement. The dual-tone multi-frequency signal is transmitted as an indicator of longitude and/or latitude change of location of the portable computing device. The origin of an emergency voice call can be determined based on a location area identifier that corresponds to a geographical area encompassing a geographical location being represented by the location data. In addition, the origin of an emergency voice call can be determined based on the cellular base station, or other station of communication of a portable computing device, and transmitted to a public safety answering point.
