Patent CA-2233555-A1 (CA)
Inventor: KNIGHT BRIAN J
IPC: H04L47/6275
Filed: 1996-09-23
Abstract: A switching device for switching ATM cells from a plurality of network input links to a plurality of network output links comprises a plurality of ports containing line interfaces and input and output buffers, a hardware switch controller, a microprocessor, and memory for storing routing tables and system software. All these elements are interconnected via a processor bus, and additionally, the ports are interconnected by a separate switching bus. The switch controller employs hash-based routing table indexing to route cells from selected input ports to appropriate output ports according to the cells' header information. Switch requests generated by incoming cells are arbitrated using a token bus allocation scheme. The majority of cells are switched almost entirely in hardware, but the microprocessor can assume control of the switching architecture to resolve exception conditions and to perform special processing on selected virtual circuits. Two output buffers perport are provided; one for high-priority cells, another for lower priority cells. Additionally, a common overflow buffer is provided to temporarily store cells intended for output buffers momentarily full.

Title: Inflatable reversible life raft
Inventor: HIGGINBOTHAM PAUL
IPC: B63C9/06
Filed: 1997-10-22
Abstract: An inflatable life raft incorporates upper and lower canopies (28, 30) that are raised automatically above the upper or lower sides of the raft, respectively, d epending on which side of the raft is facing upwardly when the raft is floating. The cano pies each form a tent-like enclosure when raised to protect the raft occupants. The c anopies are selectively raised by a generally vertically-oriented pillar (20) slidably j oined to the raft body, each end of the pillar being joined to corresponding upper and lo wer canopies. Preferably, the pillar is capable of floating to permit it to elevate above the raft body. The pillar may comprise an inflatable elongate member that slides wit hin an aperture (21) within the floor. A skirt (24) joins the pillar to the floor an d provides a reversible waterproof seal between the pillar and the floor and limits the ran ge of vertical travel of the pillar. One or more drain holes (25) may be provided with in the base of the skirt to allow the occupants to drain water from within the raft. A waterproof cover (26) protects the drain holes, and may be drawn up around the p illar after the water has been drained to prevent water from entering the raft. The ra ft may alternatively incorporate but a single canopy on one side of the raft, for use i n calmer waters where accidental inversion of the raft is unlikely.

Title: Mount for a punching bag
Inventor: LAUDENSLAGER ANDREW R
IPC: A63B71/02
Filed: 1998-12-03
Abstract: A mount for securing a punching bag or other exercise equipment to a support structure has a helical spring nested around a rotatable, slidable rod. The resulting structure relieves torsional stresses and absorbs longitudinal forces experienced by the punching bag or other exercise equipment during its use, thus prolonging the life of such bag or equipment. The nested or non-serial connection of elements in the mount shortens the operative length of the mount, which is advantageous when the vertical mounting location for the bag or equipment is limited, such as by the presence of a standard ceiling.

Title: A system and method for sending multiple data signals over a serial link
Inventor: LEE DAVID D
IPC: H04N7/52
Filed: 1997-06-13
Abstract: A system and method for sending multiple data signals over a serial link comprises an embedding unit and a removing unit coupled by a serial line. The embedding unit preferably receives a plurality of data streams, encodes the data streams and then merges the encoded data into a serial stream that is output across a serial line to the removing unit. The removing unit receives a serial stream of data, decodes the serial stream, and then separates the decoded serial stream into separate streams thereby reconstructing the streams input to the embedding unit. The encoding and transmission by the embedding unit and the receipt and decoding by the removing unit are completely transparent, the signals output by the removing unit are identical in timing and data content to the signals input to the embedding unit. The present invention also includes a method for transmitting a plurality of data streams over a signal line, and a method for generating a plurality of data streams from a serial sequence.
