Abstract: A dual link transmitter constructed according to the present invention employs a single Phase Locked Loop (PLL) to service both a primary link and a secondary link during dual link mode operations. The structure of the dual link transmitter includes both a primary link PLL and a secondary link PLL. The primary link PLL produces a primary link clock and the secondary link PLL produces a secondary link clock. During dual single link operations, the primary link clock is used to service the primary link while the secondary link clock is used to service the secondary link. However, during dual link operations, the primary link clock is used to service both the primary link and the secondary link.

Abstract: The present invention is directed to a system and method for searching and retrieving location information associated with one or more points of interests, whereby the search criteria can be dependent upon the location of a point of interest with respect to the real-time position of the user, and any preferences or search restrictions selected by the user, such as rating information about the point of interest. Upon selecting a point of interest from the search result, the user is then given further information regarding the selected point of interest, including but not limited to directions for traveling to the point of interest. Additionally, the present invention can provide to the user a proximity notification once the user is within a certain distance from the point interest.

Abstract: The present invention is directed to a method and apparatus for storing, referencing, retrieving, and graphically displaying spatial and non-spatial related information of a mobile computing device, such as a laptop computer or a cellular telephone. The spatial-related information may be obtained by using positioning tracking systems such as a global positioning system, whereas the non-spatial related information may include communication activities associated with the mobile computing device, such as phone calls, e-mails, text messages, pages, etc. The present invention also provides methods and apparatus of summarizing the spatial and non-spatial related information for more effective and intuitive display of the information to the user, including the use of graphical map and calendar of events.

Abstract: The preferred embodiments of the present invention are directed to methods and systems for dynamic route estimation and prediction using discrete sampled location updates from various mobile devices for the purpose of providing a graphical representation of a mobile device's route along a known network path of map data. The embodiments also provide supplemental route metrics, such as traveled distance, elapsed time, etc., and the capability to assign destination points for the purpose of providing the ability to modify location update points in an application, such as a route planner, and/or to store the dynamically generated route based on various preferences for later retrieval.

Abstract: The present invention is directed to a method and apparatus for recording and generating additional information related to telecommunication events using a mobile communication device, such as a telephone call or a text messaging event using cellular phone or a personal digital assistant. Specifically, the preferred embodiments of the present invention records information such as GPS coordinates that indicate a position of the mobile communication device during the communication event, as well as a location of a sender or receiver of data to or from the mobile communication device, so as to facilitate a log entry of the position of the mobile communication device as well as other useful information that are associated with the communication events.

Abstract: The present invention is directed to a method and apparatus for sending and retrieving location relevant information to a user by selecting and designating a point of interest that is displayed on a graphical user interface and sending the location information associated with that point of interest to a receiver that is also selected using the graphical user interface. The location relevant information may also include mapped routes, waypoints, geo-fenced areas, moving vehicles etc. Updated location relevant information may also be continuously sent to the user while generating updated mapping information on the graphical user interface. The present invention may be practiced by using communication devices such as a personal computer, a personal digital assistance, in-vehicle navigation systems, or a mobile telephone.

Abstract: The present invention is directed to a system and method for collecting and maintaining an up-to-date database of points of interests, whereby agents of the points of interests, such as owners or operators of hotels or restaurants, can register their point of interest onto the database by uploading their contact information and physical address. Subsequently, on a periodic basis, the agents of the points of interests may log into the system and update their information, such as operating hours. The collected data is then made accessible to the general public and can be searched through using a variety of search criteria.

Abstract: The present invention is directed to a system and method for providing real-time position information of one party to another party by utilizing a conventional telecommunication network system such as the convention telephone network, a mobile telecommunications network, a computer network, or the Internet. More specifically, the preferred embodiments of the present invention allow a caller and a receiver of a telephone call to provide to and receive from each other position information related to the caller and/or receiver's physical location, including address information, GPS coordinates, nearby fixed locations such as a parking structure, etc. Additionally, the preferred embodiments of the present invention allow a caller and receiver to retrieve routing instructions or maps for traveling to or from each other.

Abstract: One embodiment of the present invention uses an abbreviated blanking period, in comparison to the standard VESA and CEA-EIA blanking periods, in order to send data, including low bandwidth, non-timing information, over one or more channels of the digital video link. By shortening the blanking period, the amount of time available for sending data in each scan line is increased, enabling the system to send more data over each channel. The inactive video portion of a scan line sent during vertical sync may also be used to send additional digital data. Shortening the blanking periods and/or using the inactive video sections of the horizontal scan lines adds to the overall data capacity of the link and may be used to send other digital data, such as multi-channel audio, video, control, timing, closed captioning or other digital data.

Abstract: The present invention relates to a system and method for increasing the digital data capacity of a digital video link without increasing the pixel clock rate. The invention uses a shorter blanking period than the standard blanking period, in order to send more data over each channel of the digital video link. By shortening the vertical and horizontal blanking periods, the amount of time in each scan line available for sending data is increased. The inactive video portion of a scan line sent during vertical sync is also used to send auxiliary digital data, which could be additional channels of digital audio or other digital data.
