  • Patent number: 8046261
    Abstract: A mobile terminal is enabled to conduct an EMV transaction. A wireless access node in the EMV card-reader terminal is provided for connecting a mobile terminal to the card-reader terminal. An EMV-proxy module executing in the card-reader terminal facilitates communication between the mobile terminal and the card-reader terminal. The EMV-proxy module lets the mobile terminal function in essentially the same way as a regular EMV chip card with respect to the card-reader terminal. The card-reader terminal may then conduct EMV transactions on behalf of the mobile terminal without requiring new software and/or hardware at the EMV issuer. EMV data is stored in the mobile terminal in the form of secure dynamic data objects. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

  • Publication number: 20110256849
    Abstract: Communications of a mobile station with a satellite mobile communications system and a terrestrial mobile communications system are coordinated. The mobile station is registered with the terrestrial mobile communications system and, responsive to the registration of the mobile station with the terrestrial mobile communications system, the mobile station is concurrently registered with the satellite mobile communications system. The concurrent registration may include implicitly registering the mobile station with the satellite mobile communications system, e.g., by storing information identifying the mobile station may be stored in a location register of the satellite mobile communications system responsive to the registration of the mobile station with the terrestrial mobile communications system, and maintaining synchronization between the two registrations. Authentication tokens may be pre-generated for quick re-registration with a satellite mobile communications system.

  • Publication number: 20110212694
    Abstract: A first and/or a second communications system may provide communications service over a geographic area. A method of operating the first and/or the second communications systems may include generating a measure of aggregate interference reaching a satellite of the second communications system substantially from devices of the first communications system. The measure of aggregate interference reaching the satellite of the second communications system may be transmitted to an element of the first communications system.

  • Publication number: 20110141240
    Abstract: A method includes reducing a red rivalry through adjusting a color temperature on a first image, converting the first image from the RGB domain to a YCbCr domain, shifting a hue of a red color in the first image towards a magenta color to reduce a red color vibrancy, and adjusting a blue color in the first image such that a dark blue visible through a second lens corresponding to a second image is at least partially visible through a first lens corresponding to the first image. The method also includes reducing the red rivalry through adjusting a tone of the red color in the first image towards a brown color, converting the first image from the YCbCr domain back to the RGB domain, adjusting a color saturation in the first image, and combining the first image with the second image in a processor to generate an anaglyph image.

  • Publication number: 20110141349
    Abstract: A method includes projecting motion vectors describing a transformation from a previous video frame to a future video frame onto a plane between the previous video frame and the future video frame, detecting potential artifacts at the plane based on an intersection of a cover region and an uncover region on the plane, and analyzing a dissimilarity between a trial video frame and both the previous video frame and the future video frame. The trial video frame is generated between the previous video frame and the future video frame based on a frame rate conversion ratio derived from a source frame rate and a desired frame rate. The method also includes estimating reliability of the projected motion vectors based on the potential artifact detection and the dissimilarity analysis.

  • Publication number: 20110103273
    Abstract: A Frequency Division Duplex (FDD) wireless terminal includes spaced-apart antennas that are configured to transmit over a return link and to receive over a forward link that is spaced apart from the return link in frequency. The FDD wireless terminal is configured to selectively refrain from transmitting over the return link from at least one of the spaced-apart antennas of the FDD wireless terminal in response to differentials in forward link power that is received at the spaced-apart antennas of the FDD wireless terminal, that are caused, for example, by blocking appendages of a user of the wireless terminal. Related methods are also described.

  • Publication number: 20100149216
    Abstract: A mechanism for enabling a user to vary the scale or zoom of image data for aspect ratio conversion using a graphical user interface is disclosed. A user may move a selector of the graphical user interface to one end for selecting a linear scaling, to the other end for selecting a parabolic scaling or in between for selecting a scaling associated with another function, thereby enabling a user to vary the magnitude of the scaling across the image data. A parametric function with a single parameter may be used to scale the image data, where the movement of the selector may change the parameter and consequently vary the scaling of the image data. In this manner, a user may efficiently vary or select the scaling of the image data using a graphical user interface to reduce objectionable distortion associated with changing the aspect ratio of the image data.

  • Publication number: 20100142844
    Abstract: In a deblocking operation, pixel values within a first block of pixels are compared, and pixel values in the first block are also compared to pixel values in a second block of pixels that is adjacent to the first block. Based on the results of the comparisons, a digital deblocking filter and a region of interest can be selected, where the region of interest identifies a number of pixels in the first block and a number of pixels in the second block to which the selected filter is to be applied.
