| 20100208587 | METHOD AND APPARATUS FOR DISTRIBUTING CREDITS TO MULTIPLE SHAPERS TO ENABLE SHAPING TRAFFIC TARGETS IN PACKET COMMUNICATION NETWORKS - A computer based system and method for distributing a global shaper rate implemented across multiple traffic processing devices. A controller distributes credits according to the demand (amount of traffic, or offered load) of each device, in such a way to achieve global targets, including the shaper rate, strict prioritization of traffic, WFQ weights and fairness between cloned channels, iteratively updated as changes occur in the quantity and makeup of the traffic across the devices | 08-19-2010 |

| 20080277196 | Engine and technique for generating an acoustic signal - A device for generating an acoustic signal in a fluid includes an engine operable to repeat a thermodynamic process to vibrate a membrane of the engine to generate an acoustic signal having more than one period. The thermodynamic process includes heating mass inside a chamber of an engine to generate pressure inside the chamber; in response to generating the pressure, moving in a first direction a portion of a membrane of the engine; removing mass from inside the chamber to decrease the pressure inside the chamber; and in response to decreasing the pressure inside the chamber, moving the membrane portion in a second direction. Because the engine repeats the thermodynamic process, the engine can generate and sustain an acoustic signal for a significant amount of time. In addition, because the heat in the engine's chamber is generated by a chemical reaction, the engine may quickly generate a significant amount of pressure inside the chamber to quickly accelerate the membrane, and thus generate a powerful acoustic signal. Furthermore, various properties of the membrane and/or the thermodynamic process may be modified to tune the acoustic signal to a desired frequency and/or amplitude. Thus, the engine may be effectively used to generate acoustic signals for a number of different purposes, such detecting and ranging objects in a region, and in a number of different marine environments, such as a littoral environment that contains a large amount of noise, or a deep sea environment at high water pressure. | 11-13-2008 |

| 20090252356 | SPATIAL AUDIO ANALYSIS AND SYNTHESIS FOR BINAURAL REPRODUCTION AND FORMAT CONVERSION - A frequency-domain method for format conversion or reproduction of 2-channel or multi-channel audio signals such as recordings is described. The reproduction is based on spatial analysis of directional cues in the input audio signal and conversion of these cues into audio output signal cues for two or more channels in the frequency domain. | 10-08-2009 |

| 20080253144 | Semiconductor light engine using polymer light pipes and lighting systems constructed with the light engine - A light engine for use in systems such as automotive lighting systems employs two or more semiconductor light sources, such as LEDs. Light emitted from the light sources is captured by light pipes which are mounted such that the light capturing surface of the light pipes are properly positioned, with respect to the semiconductor light sources, substantially independent of changes in the dimensions of the light pipes which may result from thermal expansion or contraction of the light pipes. The light pipes transfer substantially all of the light captured from the semiconductor light sources to light emitting surfaces of the light pipes which can be appropriately located adjacent the output optics of the lighting system. The light engine can be easily assembled as the light pipes are retained in slots on a positioning member which is mounted at a known position with respect to the semiconductor light sources. | 10-16-2008 |
| 20090016074 | Semiconductor light engine using glass light pipes - A light engine for use in systems such as automotive lighting systems employs two or more semiconductor light sources, such as LEDs. Light emitted from the light sources is captured by light pipes which are mounted such that the light capturing surface of the light pipes are properly positioned, with respect to the semiconductor light sources. The light pipes transfer substantially all of the light captured from the semiconductor light sources to light emitting surfaces of the light pipes which can be appropriately located adjacent the output optics of the lighting system. The light engine can be easily assembled as the light pipes are in modules including a carrier member that can be mounted to a positioning member which also includes apertures to position the light capture surfaces of the light pipes at a known position with respect to the semiconductor light sources. | 01-15-2009 |
