Abstract: The present disclosure provides an acoustic hollow core door comprising a door slab including an inner door frame, a first facing secured to a first side of the inner door frame, and a second facing secured to a second, opposite side of the inner door frame. The inner door frame and the first and second facings define an at least partially hollow air cavity, and at least one of the first or second facings has a thickness between about 0.150 and 0.320 inches and a nominal density of between about 0.80 and 1.1 grams per cubic centimeter. The hollow core door may include internal sticks or core inserts positioned within the hollow air cavity between the first and second facings. Acoustically absorptive material may be positioned within the hollow air cavity to reduce resonance effects around 250-315 Hz frequency range. The acoustic hollow core door achieves STC ratings of between about 25 and 31, while maintaining weight reduction compared to solid core doors with comparable acoustic performance.

Abstract: Aspects of the present disclosure describe a lite unit frame and a system and method for power unit integration into a lite unit frame.

Abstract: Methods and systems for monitoring multiple services provided via multiple systems. Status information for each of the multiple services is received. Status information comprises information about delivery of information technology, voice, data, or Internet service to multiple locations. The status information is assembled into a portal that when displayed provides a concurrent view of the status information for at least some of the multiple services. The portal is updated with status information based on receiving periodic status updates to the status information for each of the multiple systems. The status information from each of the multiple services is monitored to provide diagnostics through the portal pertaining to each of the multiple systems. Additionally, based on receiving notice of an error, tests may be run to identify the nature and extent of an anomaly or error.
