    摘要: A method for dynamically configuring a video stream, including: identifying player control metadata attributes for an input video stream, wherein the input video stream is received from an origin server; storing the identified metadata attributes to a memory device; and dynamically inserting the metadata attributes into an output video stream in real-time.

    摘要: A drive system for a refrigeration compressor such as is used in a natural gas liquefaction plant, allowing the desired compressor speed and maximum turbine efficiency to be maintained throughout varying ambient temperature conditions. A gas turbine is used with an electric starter motor with drive-through capability located on a common drive shaft between the turbine and the compressor. A variable frequency drive (VFD) is connected between the electrical power grid and the electric motor for smooth startups, but also to allow excess turbine mechanical power to be converted to electrical power by the motor operating as a generator, and delivered to the grid at the grid frequency. Pulse width modulation technology may be used to reduce harmonic distortion in the VFD's output. The starter motor also functions as a helper motor when the turbine output is insufficient to drive the compressor at the rotational speed needed to meet throughput requirements.

    摘要: A light coupler and modulator for an optical waveguide is formed using a slab of optically transmissive material having a higher index of refraction than the waveguide. The slab has tapered ends for receiving and transmitting light from and to the waveguide. An electrode is disposed over the slab for the application of modulating signals to the slab. When used as a coupler, the ends of two waveguides to be coupled also have tapered ends that are overlapped by the slab with the tapered ends of the slab extending beyond the taper of the waveguides.
