Title: Covered pad for wall panel and manufacturing process
Inventor: WILSON HAROLD R
IPC: E04B2/74
Filed: 2004-12-15
Abstract: A cover pad for an upright wall having an improved support for simplifying attachment of a flexible covering such as fabric. The support includes a flat substrate sized to closely conform to the assembled cover pad. A ringlike frame defined by frame elements extend along edges of the substrate. Each frame element has a first elongate part engaged with the respective edge of the substrate, and a second elongate part joined to the first part by a lengthwise hinge. The second part functions as a hinging flange which is initially in an open position generally aligned with a front face of the substrate so that a flexible covering can be secured, as by adhesive, to an exposed surface of the flange while maintaining the fabric positioned across the face of the substrate. The hinging flanges of the frame elements are folded inwardly to overlie respective edges of the substrate, thereby securing the fabric across the face of the substrate and wrapped around the edges thereof.

Title: A scalable approach to large scale queuing through dynamic resource allocation
Inventor: FULLI ALESSANDRO
IPC: H04L12/56
Filed: 2004-08-03
Abstract: Methods and devices are provided for the efficient allocation and deletion of virtual output queues. According to some implementations, incoming packets are classified accordint to a queue in which the packet (or classification information for the packet) will be stored, e.g., according to a "Q" value. For example, a Q value may be a Q number defined as {Egress port number I  I Priority number II Ingress port number}. Only a single physical queue is allocated for each classification. When a physical queue is empty, the physical queue is preferably de-allocated and added to a "free list" of available physical queues. Accordingly, the total number of allocated physical queues preferably does not exceed the total number of classified packets. Because the input buffering requirements of Fibre Channel ("FC") and other protocols place limitations on the number of incoming packets, the dynamic allocation methods of the present invention result in a sparse allocation of physical queues.
