Title: Quick release in-line skate wheel axle
Inventor: POST PETER G
IPC: A63C17/22
Filed: 1997-12-24
Abstract: An axle for in-line roller wheels allowing quick release of the wheels and axle from the in-line skate blade frame. The axle is constructed and arranged to allow the distal ends of the axle to move longitudinally relative to each other. There is a spring or other such mechanism forcing the ends of the axle into the openings in the blade frame. The ends of the axle that protrude into the frame are designed not to protrude beyond the outer sides of the frame structure so that the ends of the axle are not subject to wear. The present invention provides for an in-line skate axle that is secure and never needs tightening. Since the wheels are retained by springs there are no bolts or threaded connections to become loose. Other types of construction retain the axle and wheel in the blade frame using spring forces in tension rather than compression. In such arrangements the spring is stretched through the axle and the end retainers are pulled into place thereby retaining the axle and wheel to the frame. Other such arrangements such as bayonet type retaining locks may be used to advantage in the present invention.

Patent CA-2236394-A1 (CA)
Title: Programmable transport and network architecture
Inventor: BESHAI MAGED E
IPC: H04L12/56
Filed: 1998-04-30
Abstract: This invention relates to the design of a scaleable high performance multiservice network based on programmable transport. A meshed network with dynamically-adjustable link capacities and nodes which provide data packing into "containers" for transport is proposed. A  ring-based network, exchanging data containers among its nodes, is the preferred implementation, due to its flexibility, maintainability, and high reliability. With lossless rings, the quality of service is controlled solely by the origin and destination nodes, without any interference from other data streams. Flexible programmable transport greatly improves the performance, simplifies the controls, and facilitates scaleability. The concept is a departure from classical network thinking. By reducing the complexity of the network core, an economical, reliable, and manageable network with feature-rich edge nodes can be realized. An architecture with recursive ring-based structures provides a high degree of flexibility in bandwidth allocation and is compatible with current transport networks and future all-optical networks.

Title: Gameboard
Inventor: MCTAGGART STEPHEN I
IPC: A63F3/02
Filed: 1996-11-05
Abstract: An electronic gameboard (1) includes a foldable sheet, each side of which is divided into first and second sections. On one side, a conductive ink printed circuit, including a plurality of switch contact pads (10, 11) is laid down such that upper contacts (10) register with lower contacts (11) to effect a switch pair when the sheet is folded. A spacer expedient of dielectric ink (19), thicker than the conductive ink, is employed to juxtapose the upper and lower contacts (10, 11) of each switch pair in a normally open condition such that finger pressure selectively effects a momentary closure. The printed circuit also includes traces coupling all the contacts to a decoder (55) which senses if a switch pair is closed. A gameboard layout is provided on the second side of the sheet and includes indicia identifying the position of each gameboard layout. Signal producing apparatus, such as a sound unit, responds to the closure of a given switch pair by issuing an appropriate, predetermined signal passage. In order to permit folded storage of the gameboard, one section is bifurcated by a slot which facilitates a temporary fold.

Patent CA-2240687-A1 (CA)
Title: Method for managing multicast addresses for transmitting and receiving multimedia conferencing information on an internet protocol (ip) network implemented over an atm network
Inventor: SHUR DAVID HILTON
IPC: H04L29/06
Filed: 1998-06-15
Abstract: In a multicast capable IP network implemented over an ATM network, each client terminal on a multimedia conference, for each media type it transmits, is assigned a multicast IP address and a port number (together known as a socket) on which to transmit packets, wherein each assigned multicast IP address is unique and different than the multicast IP address assigned to any other client for any media type. Each client terminal then selects, for each media type, which clients on the conference it wants to receive packets from. Only packets that are in fact requested by a client are routed over the multicast IP network to the requesting client. A single special purpose Multicast Address Resolution System (MARS) server is associated with the conference when the conference is established. Each client terminal uses that MARS server, whether on the same or different IP sub-networks, but on a common ATM network, for purposes of mapping the multicast IP addresses used in the conference into a set of unicast ATM endpoint addresses used by the ATM-connected client terminals. Similarly, when a specific conference uses a Multicast Server, a single special purpose Multicast Server is used for all clients on the conference, whether on the same or different IP sub-networks, for purposes of establishing point-to-multipoint ATM connections to the conference endpoints.
