  • Publication number: 20110156937
    Abstract: A multi-speed burst mode serializer/de-serializer (SerDes) is configurable and can operate in one of a plurality of operating modes. The plurality of operating modes correspond to the reception of signals from optical network units that operate at different nominal speeds. These various modes of operation can enable a single SerDes design to apply to a variety of speeds and network configurations (e.g., point-to-point or point-to-multipoint). In one example, the design can be initially configured for operation with a single ONT or a network of ONTs at a single speed, or can be dynamically configured during operation for use with a network of ONTs operating at different speeds.

  • Publication number: 20110157170
    Abstract: Applications are provided that contain code of a programming language enabling simultaneous display on a screen of both two-dimensional and three-dimensional content. Furthermore, development systems and program libraries supporting the same are provided. A first command is generated by first program code of an application. The first command directs a first configuration of a first region of the screen to support the three-dimensional content. A second command is generated by second program code of the application. The second command directs a second configuration of a second region of the screen to support the two-dimensional content. The display of the three-dimensional content is caused within the first region of the screen, and the display of the two-dimensional content is caused within the second region of the screen.

  • Publication number: 20110157327
    Abstract: Techniques are described herein for supporting 3D audio delivery accompanying 3D display supported by viewer/listener position and orientation tracking. For example, audio content is configured to have a spatial orientation that accords with an orientation of a viewer. A spatial orientation of audio content is a configuration of the audio content in which characteristics of respective portions of the audio content, which correspond to respective speakers, indicate an orientation of ears of a viewer/listener with respect to sound source(s) that correspond to (e.g., are depicted in) a three-dimensional view. Such a characteristic may include an amplitude of sound that corresponds to a sound source and/or a delay associated with the sound that corresponds to the sound source.

  • Publication number: 20110157336
    Abstract: A display system is provided that enables three-dimensional images to be displayed. The display system includes an elastic light manipulator positioned proximate an image generator. The image generator includes a pixel array. The elastic light manipulator includes an elastic material and is mounted in a manner that allows for automated stretching thereof. For instance, the elastic light manipulator may be an elastic lenticular lens, an elastic parallax barrier, etc. Because the elastic light manipulator can be stretched, optical properties of the elastic light manipulator can be dynamically modified, thereby changing the manner in which light emanating from the pixel array is delivered to the eyes of viewer(s). This allows for adaptive accommodation of, for example, a changing viewer sweet spot. The elastic light manipulator may be automatically rolled up or otherwise automatically removed from in front of the image generator in order to facilitate switching between 2D and 3D views.

  • Publication number: 20110158137
    Abstract: Systems and methods are used to adjust, e.g., reduce, current driving a transmitter, i.e., to reduce transmitter power consumption, based on an actual value of a received signal from received along a cable. For example, this is very beneficial to an Ethernet system where the received signal is attenuated by the lossy cable. In this case, the transmitter power consumption can be lowered during a normal application where data is transmitted and received through the cable.
