| 20110274156 | SYSTEM AND METHOD FOR TRANSMITTING MULTIMEDIA STREAM - Systems and methods for transmitting a multimedia stream are disclosed. A transmitter encodes audio data, video data, and control information received from a source and transmits over a network the different types of data to a receiver coupled to a display. The systems and methods utilize different network queues for the different types of traffic in order to account for differences in quality of service (QoS) parameters. The systems and methods adaptively adjust encoding and transmission parameters based on monitoring changing conditions of the network. | 11-10-2011 |
| 20110276710 | SYSTEM AND METHOD FOR LOW-LATENCY MULTIMEDIA STREAMING - Systems and methods for transmitting a multimedia stream over a communication link on a network are disclosed. The systems and methods adaptively adjust encoding parameters based on monitoring changing conditions of the network. A transmitter includes an adaptive-rate encoder that adaptively adjusts a video encoding bit rate in response to changing conditions of the communication link. The encoder maintains tight rate control by utilizing slice processing and sub-frame rate adaptation, as well as maintaining a headroom between the channel bit rate and the video encoding bit rate. The adaptive-rate encoder also embeds intra-frame constraints in predictive frames traffic in order to reduce latency. | 11-10-2011 |

| 20090310672 | Method and System for Rate Control in a Video Encoder - A method and system for a rate control block that adjusts the Quantization Parameter (QP) for a frame or macroblock based on the number of bits already used in encoding the frame or macroblock is disclosed. In an embodiment of the invention, the QP for a macroblock is adjusted dynamically against the QP for a frame as a function of the buffer occupancy. In another embodiment of the invention, a range of allowable QPs are defined based on the buffer occupancy. Embodiments of the invention are applicable to H.264 high-definition video conferencing. | 12-17-2009 |

| 20090270809 | DEVICE AND METHOD FOR CONNECTING A BLOOD PUMP WITHOUT TRAPPING AIR BUBBLES - An apparatus and a method for connecting medical tubing or any other type of fluidic circuit conduits (e.g., cannulae) to a ventricular assist device (“VAD”) or any other pumping device used for blood pumping during cardiac circulatory support for vascular surgery. The apparatus and the method prevent air bubbles from entering a cardiac circulatory support system when connecting cannulae to a VAD that may later enter the blood stream of a patient during cardiac surgery, and also provide for purging any air bubbles that may have entered the cardiac circulatory support system during a cannulae-VAD connection. | 10-29-2009 |

| 20120031192 | Semiconductor strain gauge array - A strain monitoring system including an array of semiconductor strain gauges. Each strain gauge in the array of strain gauges includes a lithographically fabricated 4-resistor bridge for providing a voltage potential corresponding to the strain in the bridge and thin film transistors to provide addressability to each 4-resistor bridge in the array. After completion of the array of strain gauges, in preferred embodiments the array of strain gauges are transferred to polyimide film which is in turn bonded to a surface region of the component to be tested for strains. Each bridge provides voltage signals corresponding to the strain to which the material under the bridge is being subjected. In preferred embodiments control and data acquisition function are separated from the semiconductor strain gage array. Preferred embodiments the system are utilized to monitor strains on components of aircraft, especially light weight robotic aircraft. | 02-09-2012 |
