20090230273	SUSPENSION SYSTEM - A system is provided for suspending a plurality of line array loudspeakers. The suspension system includes a rigging bar having an engaging member, such as a pivotal member, positioned near one end of the rigging bar. The engaging member includes a free end capable of extending outward past the end of the rigging bar in which the engaging member is positioned. The end of the rigging bar opposite the pivotal member is designed to releasably receive an engaging member of an adjacent rigging bar. The free end of the engaging member of the rigging bar may include a hole that aligns with holes positioned in the receiving end of the rigging bar. The engaging member of one rigging bar may then be secured to an adjacent rigging bar by aligning holes of the engaging member of a first rigging bar with the holes in the receiving end of a second rigging bar and inserting a release pin through the aligned holes.	09-17-2009

20110029676	PER PRIORITY TCP QUALITY OF SERVICE - An IP gateway device establishes distinct TCP sessions within a single FCIP tunnel, each TCP session being designated for a different priority of service (e.g., high, medium, low), plus a control stream. Each TCP session has its own TCP stack and its own settings for VLAN Tagging (IEEE 802.1Q), quality of service (IEEE 802.1P) and Differentiated Services Code Point (DSCP). By distributing data streams assigned to different priorities of service into different TCP sessions within the FCIP tunnel, an IP gateway device can preserve the distinctions between the data stream priorities while the data traffic is within the IP network.	02-03-2011
