Title: Universal mailbox and system for automatically delivering messages to a telecommunications device
Inventor: FORTMAN PETER A
IPC: H04M7/12
Filed: 1998-04-22
Abstract: A messaging center, connected to a communications network, processes messages intended for a subscriber. A caller sends a message to the message center in a first caller format. The message center stores the message in the first caller format, notifies the subscriber, and awaits a request for the stored message from the subscriber. In response to the message request, the message center sends the stored message to the subscriber in a first subscriber format independent of the first caller format. Alternatively, the messaging center automatically transfers the message in the first subscriber format to the subscriber equipment without requiring the subscriber to initiate the message transfer.

Abstract: Congestion at a network node can be aggravated by having too many TCP connections. A simple method of avoiding the bad effects of too many TCP connections is to limit the number of connections. Limiting the number of connections is achieved by an admission control which delays or even discards the connection set-up packets.      TCP traffic flows are monitored to generate packet loss characteristics and when a certain condition is met, a connection request queue is disabled.

Patent CA-2305822-A1 (CA)
Title: Expanded structures and method for forming
Inventor: MAKAR JOSEPH
IPC: B63B7/02
Filed: 2000-04-14
Abstract: Expanded structures are formed by cutting a series of concentric rings or sections from a single block or sheet of solid material. The "rings" need not be circular, but may be any regular or irregular geometric or other shape as desired, so long as they are substantially concentric with one another. The cuts are made so that they angle outwardly from the upper to the lower surface of the block or sheet, and pass completely through the sheet or block.      This provides a series of concentric sections, with each section having a lower, outer periphery which is at least slightly larger than the upper, inner periphery of the next larger adjacent section. This allows each section to be stacked atop a larger adjacent section, with the lower outer edge surface of each smaller section resting upon the upper inner edge surface of the larger section immediately therebelow. Alternatively, the tapered outer and inner walls or faces of adjacent sections may be wedged together, with an adjacent inner section protruding somewhat from the plane of its adjacent outer section. Such structures may be formed in virtually any practicable size, from utility sheds including door and window openings formed therein, to smaller household containers, works of art, etc. as desired. The structures may be made permanent by coating with a suitable material (e. g., glass fiber and resin, etc.) if so desired.      Different colors of materials may also be assembled together, to produce structures having alternating bands of colors therein.
