| 20090276812 | SYSTEM AND METHOD FOR LOCAL BROADCASTING - A video controller broadcasts input video through a premises media, such as a coaxial cable to one or more premises televisions or television channels. When a PC provides the input video, a mode change may occur to direct the video to the PC monitor or to the broadcast output. The video resolution of the PC is set to provide a desired digital television resolution with broadcast video. An audio driver may be used to provide USB audio output from the PC. When the PC monitor or broadcast output is selected for video output, the non-selected output is disabled or provided with a video indication that another video output is active. An EDID can be captured from the PC or PC monitor to assist with mode changes and setting PC video resolution. The input video may be provided directly from a digital video source and broadcast to selected televisions or channels. | 11-05-2009 |
| 20090276813 | SYSTEM AND METHOD FOR CHANNEL SELECTION FOR LOCAL BROADCASTING - A video controller selects a channel for premises broadcasting to a premises television based on a fast scan of signal strength in channels available over a premises media. The signal strength of certain filtered channel frequencies can be evaluated to determine if a channel is occupied. Unoccupied channels can be ranked in relation to nearby occupied or unoccupied channels. The nearby channels may be ranked in terms of the signal strength content in relation to the channel being evaluated. The video controller can select an unoccupied channel with an optimal ranking to permit premises broadcasting with reduced interference or conflict with other channels. | 11-05-2009 |

| 20120131545 | GENERATION OF CODE FROM A GRAPHICAL MODEL - A method and system are provided for generating code from a graphical model in a graphical modeling environment. The graphical model includes at least one signal having a data size, a data dimensionality, or both that can vary from a first time instance to a second time instance as the model executes. The size and dimensionality of the signal can vary without the use of a graphically rendered connection to convey the size and dimension information to a block associated with the signal. | 05-24-2012 |

| 20090132993 | MODE-SWITCHED VARIABLE SIGNAL ATTRIBUTES IN BLOCK DIAGRAMS - A programming element is provided that defines model attributes in response to mode change events in a graphical modeling environment. Such definition may involve any signal attribute such as dimensions, data types, complexity and sample times. Events that trigger definition of model attributes may be explicit signaling events generated by other elements, elements within the block diagram programming environment, and elements external from the environment. Implicit events may also trigger definition of model attributes, such as a change of attribute in an input signal. | 05-21-2009 |

| 20090007064 | Size vector sharing in code generated for variable-sized signals - A method and apparatus to generate code to represent a graphical model formed of multiple graphical modeling components and at least one variable-sized signal is presented. Each variable-sized signal is represented using a size-vector in the generated code. The generated code is optimized by representing multiple variable-sized signals with the same size-vector such that at least two variable-sized signals share a size-vector in the generated code. The size of the variable-sized signal is capable of changing during the execution of the graphical model. The method and apparatus also identifies the owners of the variable-sized signals. | 01-01-2009 |

| 20110121867 | HIGH-SPEED COMPRESSION ARCHITECTURE FOR MEMORY - Memory design techniques are disclosed that provide a high compression ratio at no loss in speed. The techniques can be embodied, for instance, in heterojunction bipolar transistor (HBT) based ROMs. By embedding compression logic (e.g., XOR) functionality directly into the address decoders and sense amplifiers of the memory device, a high compression ratio is achieved at no loss in speed. For example, the logic-based compression functionality can be directly implemented into the buffers that form the address decoder as well as the sense amplifiers. | 05-26-2011 |
| 20110121881 | MULTIPLE INPUT / GAIN STAGE GILBERT CELL MIXERS - Multiple input and/or gain stage Gilbert cell mixer designs are disclosed. The designs allow one input to be turned on at a time, and are suitable, for example, for use in receiver and transmitter applications. In addition, the designs allow for the inputs of the multi-input Gilbert cell mixer to be connected together, thereby allowing for switching of gain states within the Gilbert cell mixer. The mixer design may include, for example, a Gilbert cell mixer stage, and a plurality of input/gain stages. Each input/gain stage has its output connected to the input of the mixer stage, and is configured for receiving an input signal and applying a gain factor to that input signal to provide a signal for mixing with the LO. Each input/gain stage is configured with stage select circuitry for enabling or disabling that stage, so that only one input/gain stage is active at a time. | 05-26-2011 |

| 20110285807 | Voice Tracking Camera with Speaker Identification - A videoconferencing apparatus automatically tracks speakers in a room and dynamically switches between a controlled, people-view camera and a fixed, room-view camera. When no one is speaking, the apparatus shows the room view to the far-end. When there is a dominant speaker in the room, the apparatus directs the people-view camera at the dominant speaker and switches from the room-view camera to the people-view camera. When there is a new speaker in the room, the apparatus switches to the room-view camera first, directs the people-view camera at the new speaker, and then switches to the people-view camera directed at the new speaker. When there are two near-end speakers engaged in a conversation, the apparatus tracks and zooms-in the people-view camera so that both speakers are in view. | 11-24-2011 |

| 20120004918 | Full-Band Scalable Audio Codec - A scalable audio codec for a processing device determines first and second bit allocations for each frame of input audio. First bits are allocated for a first frequency band, and second bits are allocated for a second frequency band. The allocations are made on a frame-by-frame basis based on the energy ratio between the two bands. For each frame, the codec transform codes both frequency bands into two sets of transform coefficients, which are then packetized based on the bit allocations. The packets are then transmitted with the processing device. Additionally, the frequency regions of the transform coefficients can be arranged in order of importance determined by power levels and perceptual modeling. Should bit stripping occur, the decoder at a receiving device can produce audio of suitable quality given that bits have been allocated between the bands and the regions of transform coefficients have been ordered by importance. | 01-05-2012 |

The region of interaction has a deterministic, aperiodic patterning with an array of individual patterning elements of distinct refractive indices such that a variation of refractive index of the device occurs over distances comparable with a wavelength of the incident electromagnetic energy, the array being a multi-dimensional extension of a corresponding one-dimensional sequence such that a spectral response of the array is a multi-dimensional equivalent of a spectral response of the one-dimensional sequence. Specific examples employing so-called Rudin-Shapiro, Thue-Morse and Fibonacci sequences are shown. | 08-06-2009 |
