  • Patent number: 8348020
    Abstract: An elevator control device includes a vector controller that calculates a voltage command required for driving an elevator cage, a carrier frequency switch circuit that outputs a carrier frequency signal, and a power converter that performs PWM control based on the voltage command and the carrier frequency signal, generates an AC power and supplies the AC power to an AC motor. The carrier frequency switch circuit changes the carrier frequency signal when a torque command for driving the AC motor reaches a torque limit value. Thus, it is possible to continuously operate an elevator without causing damage to a switching element of the power converter.

  • Patent number: 8136142
    Abstract: A centralized Content Management System (“CCMS”) facilitates management of packages comprising assets comprising meta-data and associated content of video programs for distribution to various types of service providers and equipment locations therein. The CCMS can receive meta-data and associated content, normalize the meta-data according to various formats based on various rules depending on where the meta-data and contents are to be distributed, and the distribute the content. The CCMS has various capabilities for managing packages, including adapting the meta-data and content for different types of equipment or individual locations based on rules for that service provider, thus providing an automated system reducing error and time in distributing video assets to a number of locations.

  • Patent number: 8126318
    Abstract: A system, which minimizes a time delay caused by one device being unable to access a recording medium until access by another device ends, when transcoding is performed by distributed processing, includes a main device transcoding each coded piece allocated to itself from among a plurality of coded pieces of a digital stream, and writing a transcoding result onto the recording medium, in a pipeline. While the recording device is performing the transcoding and the writing, an auxiliary device transcodes each coded piece allocated to itself one by one. Having completed the transcoding of all coded pieces allocated to itself, the auxiliary device transmits its transcoding results to the recording device and has the recording device write the transcoding results onto the recording medium which is a copy destination.
