Abstract: A system to provide personalized promotional content using a broadcast television signal is described. Broadcast television content contains an information band called as ticker band (38) that carries promotional information along with a video signal. This promotional content is captured and stored as several images that correspond to information sets (40). This captured content that is image based is played out in the television optionally with original promotional content, thus providing a personalized promotional information band. This system enables capturing and recalling promotional information reliably for both over the air and terrestrial television broadcasts and works with existing television receivers without needing upgrades to video distribution networks.

Abstract: A dual display device is described where a single display controller (32) is used to support both displays. This is done by using the smart panel display mode of the display controller and connecting to two displays that both support smart panel display mode along with chip select signals (40) that controls when each display should process the signals. This method enables display in simultaneous display mode and mutually exclusive display mode. Using a single display controller to support an additional display enables use of existing smartphone application processors (33) that already provide an embedded display controller supporting smart panel display mode. Hence an extra display can be easily added to existing smartphone implementation with ease, without extensive redesign to schematics, power budget and associated protocols for supporting a second display controller.

Abstract: A screen sharing system that enables selective access to application data and application logic is described. This screen sharing system is implemented by coupling a helper application (36) to an application that provides content referred to as content application (35). The helper application is an application that has the ability to programmatically access the content application (35) using window system graphical user interface application programming interface. Helper application (36) is used to get and set content application data and interact with the content application using window system input events that simulate user input. This method enables selective access to both application data and application logic that is necessary for use in a screen sharing system used by participants that may be trusted or may not be fully trusted.

Abstract: A system of data entry on a surface coated with touch sensitive material is provided. This surface is referred herein as touch panel (36). This system is comprised of methods that use touch movement recognition in one of two directions up (44) and down (43) or left (54) and right (53). The touch movements are mapped to a sequential list of basic elements of a language (31). Basic elements can be alphabets (32), numerals (33), ideograms (34) and words (35). Cancellation and selection commands are optionally mapped to left (54) and right movements (53). Selected basic elements are passed onto applications in context of data entry.

Abstract: An accessory device (33) to a mobile device (31) is described that enables enhanced internet content viewing experience, where internet content is enhanced using data from accessory device (41). This is achieved by combining an embedded web proxy server (37) into the accessory device (33) with enhancements that support merging data from the accessory device (41) into internet content. This enables accessory devices (33) to be used with both closed and open mobile devices (31).

Abstract: An authentication system combining human image recognition capability to recognize transformed images, image transform element (41), and image storage element (38), and image display element (40), is implemented to enable user (32) to access a secure resource (31). Said authentication system provides a mass market solution that does not require expensive capital to implement and cannot be compromised as other authentication methods in prior art.

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.

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).

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.

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).
