  • Patent number: 8590666
    Abstract: Disclosed herein is a rigging component and method for connecting an array element in an array. The rigging component includes an elongate housing connectable to an array element; a connection link disposed within, and slidably extendable from, one end of the housing; a conduit extending into the housing from its opposite end, the conduit dimensioned to receive another connection link extending from an adjacent rigging component; and at least one latching device associated with the conduit for releasably retaining the other connection link within the conduit. Further disclosed is a system for connecting an array element in an array. The system comprises at least one rigging component having a connection link extendable to be locked at a single fixed distance and at least one rigging component having a connection link extendable to be locked at one of a plurality of fixed distances.

  • Patent number: 8421535
    Abstract: Provided are apparatuses and methods for reducing nonlinear distortions in Class D amplifiers by dynamically changing first and second threshold voltages in a pulse width modulator. A Class D amplifier apparatus is disclosed, comprising a pulse width modulator whose operation relies on a first and second threshold value, and a threshold controller which varies the thresholds in response to internal signals in the amplifier. Further, a method of processing Class D amplifier internal signals is disclosed, comprising steps involving measuring internal signals in a Class D amplifier and varying threshold signals in response to those measurements within the amplifier.

  • Patent number: 8385580
    Abstract: An acoustic transducer including a sound producing cone that is activated by a voice coil cylinder having a pair of spaced electrical windings that are retained in spaced relationship from a surround ferromagnetic ring that is carried by a heat sink and wherein a magnetic subassembly is mounted within the voice coil cylinder. The voice coil cylinder is supported by a pair of spaced suspension members or spiders and by the sound producing cone.
