Inventor: THOMAS GLENN C
IPC: G06T19/20
Filed: 1996-09-13
Abstract: A digital library of fabric models is created, preferably including digitized full-color images (74) and having associated a digital representation of positions that are located within and which characterize the models (75).

Title: Water-disintegratable fibrous sheet
Inventor: KONISHI TAKAYOSHI
IPC: D21H17/14
Filed: 1998-07-15
Abstract: A fibrous sheet coated with a water-soluble binder of polyvinyl alcohol is impregnated with an aqueous solution dissolved with water-soluble carboxylate, so as to produce a water-disintegratable fibrous sheet. Salting. out of the polyvinyl alcohol with the carboxylate maintains wet strength of the water-disintegratable fibrous sheet even in a wet state, which is easily disintegrated when immersed in a large amount of water after use. Furthermore, it does not suffer from deterioration in water-disintegratability and wet strength if it is left at high temperatures, and is good in water-disintegratability in cold water.

Title: Method and system for a unicast endpoint client to access a multicast internet protocol (ip) session
Inventor: ZELEZNIAK ALEKSANDR
IPC: H04M3/56
Filed: 1998-08-26
Abstract: Unicast endpoint clients (110, 111, 115) on an IP Unicast network (107, 108) are provided access to Multicast sessions on an IP Multicast network (101) through a Multicast-Unicast gateway server (120, 121). The server obtains information about sessions on the Multicast network and makes such information available to a Unicast client on the Unicast network upon request bythe client. Upon being presented with a list describing the subject matter of each session, the user at the Unicast client selects the session to which he or she wants to join, which causes the Multicast-Unicast server to join the appropriate session on behalf of the requesting client for each media type in which the joining client wants to be a participant. The server then sets a bi-directional Unicast User Datagram Protocol (UDP) stream between itself and the client. All packets then received by the server from the Unicast client are address-translated to the appropriate Multicast session address. In addition, all packets received by the server on the Multicast session address are address-translated and sent to the Unicast client. The Unicast client is then able to participate in the Multicast session as both a sender and a receiver of packets to and from other Unicast and Multicast clients which are active during the session. Further, the Unicast client is capable of creating a new session, recording a session in the network for later retrieval and playback, and creating and accessing low bandwidth versions of existing sessions.

Patent CA-2259485-A1 (CA)
Title: Easy toe adjustment
Inventor: GILL GEORGE MICHAEL
IPC: G01B11/275
Filed: 1998-04-20
Abstract: Current methods for adjusting toe on a steerable vehicle wheel require that the steering wheel be locked or that the total toe be adjusted. Additionally, if the wheels are locked, the mechanic cannot easily access the toe adjusting mechanism. The claimed invention provides a vehicle wheel alignment angle adjustment apparatus and method that permit toe angle adjustments without locking the steering wheel and provide that the toe adjustment can be made while the wheels are turned at angles that allow access to the toe adjustment mechanism. The apparatus and method use sensors that send infrared signals interpreted by a controller to indicate wheel alignment angles. Once the angles are obtained, stored, and compared with pre-adjustment toe values, an operator can then adjust the toe angle to within a desired specification without locking the wheel.
