  • Publication number: 20100279629
    Abstract: A mobile device (31) capable of processing radio broadcast signals (36) is described. Broadcast radio signals (36) are received by said mobile device (31) and converted to desired digital audio content format (52) and then combined with output of software applications (54) running at said mobile device (31) to create a combined radio broadcast signal (55) that can be received by a automobile broadcast radio receiver (83). Said radio broadcast signal (55) is transmitted to a automobile broadcast radio receiver (83) to enable a user to interact with audio content using software applications (54) of said mobile device (31). Transmission of combined radio broadcast signal (56) is done on a different radio broadcast frequency with low power signal.

  • Publication number: 20100271288
    Abstract: A method and device that support automatic scaling of display output of a shared application are described. Display output of a shared application from a device with large display (33) is received at a device with small display (31) and scaled down to fit the boundaries of device with small display (31). This scaled down display output is then shown as overall content (44) in background layer (40) on device with small display (31). Information about work area view (46) is also received at the device with small display (31) and is mapped to contents of the background layer (40). Then mapped contents are automatically scaled up to user defined levels and displayed in foreground layer (41). The contents of foreground layer (41) may be fixed or may be synchronized with changes in work area view (46) at device with large display (33).

  • Publication number: 20100267406
    Abstract: A method to transmit local area radio broadcast signals (38) that is coupled to wide area radio broadcast signals (39) is described. Local area radio broadcasting is used to transmit audio content from personal audio players into the audio of an automobile. Local area radio broadcast signals (38) are coupled to wide area radio broadcast signals (39) using time based or algorithm based time slot allocation methods. A personal audio player such as a smartphone (32) or a music player is enabled with a local area broadcast radio signal transmitter (53) that transmits radio signals into a desired channel (35) which may be occupied by a wide area transmitter (68). The local area transmission may be mutually exclusive or overlapping with wide area transmission. When overlapping, signal cancellation techniques may be used such that a signature signal from wide area broadcast station may be cancelled by local area broadcast.

  • Publication number: 20100251292
    Abstract: A mobile device (34) capable of processing real time broadcast television signals (36) is described. Television signals (36) are received by mobile device (34) and converted to desired digital video content (47) format and then combined with output of software applications (43) running at mobile device (34) to create a combined television signal (51) that can be displayed by a television (37). Combined television signal is sent to television (37) to enable a user (48) to interact with television content using software applications (43) executing at mobile device (34).

  • Publication number: 20090247136
    Abstract: A system and corresponding methods to provide assistance to a mobile user (42) to operate applications in the mobile device (31) is described. A call center is enhanced to enable routing mobile device application screens (43) to call center agents in addition to routing voice calls. Such a call center is referred to as remote help center. When a mobile user (42) needs assistance in operating applications (44) at the mobile device (31), he makes a call to remote help center and sends display contents from the mobile device (31) into the remote help center which routes the display contents to corresponding remote help center agents who can provide remote assistance to operate applications (44) at the mobile device (31).

  • Patent number: 7577420
    Abstract: A security system (52) using cellular wireless half duplex communication call (62) is provided. The security system (52) comprises a set of monitored resources (10), group of owners (48) and group of helpers (50) connected using said cellular wireless half duplex call (52). The monitored resource (10) is configured to generate an alarm and is coupled with said cellular wireless half duplex call (62). Said owners (48) and helpers (50) are also coupled with said cellular wireless half duplex call (62). In an event of emergency said monitored resource (10) generates an alarm and initiates said cellular wireless half duplex call (62) to connect to said owners (48) and said helpers (50) in shortest possible time without significantly contributing to cellular network load. Said security system (52) provides most scalable, efficient and viable security solution using cellular wireless networks.
