Title: Cellular communication system with mobile stations acting as relay stations
Inventor: LARSEN MARK SIEVERT
IPC: H04L12/56
Filed: 1998-03-03
Abstract: A cellular network comprises a plurality of mobile stations and a plurality of base stations. The base stations are located so that each base station has a zone of effective coverage which does not overlap with the zones of effective coverage of adjacent base stations. Thus, there are zones of reduced coverage between the base stations. When a sender station which is outside the zone of effective coverage of a particular base station wishes to send a message to that base station, the message is relayed by another mobile station to the destination base station. The relaying station may be located within the zone of effective coverage, or in the zone of reduced coverage of the destination base station. The sender station, the destination station and the relaying station(s) can all be mobile stations located in zones of reduced coverage. In the zones of reduced coverage, resources such as transmission power, transmission time-slots and frequency channels are utilised on a reduced basis, effectively sharing the resources between the stations.

Title: Para trike mountain bike
Inventor: DUGGAN DONALD RODNEY
IPC: A61G5/02
Filed: 1999-10-21
Abstract: In a personal transportation unit designed for paraplegics, this invention i s a three wheeled mountain bike for people who still retain upper body strength and dexterity and wish to have greater mobility and independence than conventional units (wheelchairs) allow.  In this invention, power is derived by hand cranks that are secured to t he outside of crankshafts (left and right) and then connected from front sprockets to rear sprockets by chain. By hand cranking with either the left or right hand, or both simultaneously (electric motors which are not shown may be added to greatly enhance the range and speed on this invention) and a lower first gear ratio due to oversized sprockets of the rear sprockets, paraplegic riders can afford easi er starts and climbs on the bike.  Safety wheels on the rear of the bike, located behind the rear wheels a nd connected by wheel stays to the frame prevent the bike from flipping over backwards when applying the brakes. Front brake levers are on opposite ends of the handlebars (left hand for left brake and right hand for right brake). Rear brake levers on the rear hand grips are to stabilize the bike for easi er entries and exits. A front-end support spring system which helps to keep the front wheel straight, with adjustable tension and shock absorbers (not shown) provides smoother riding. The seat is a full-bottom or sling (not shown) to accommodate everyone' s needs. The seat belt is a wider support belt (nylon and Velcro) with a quick release and Velcro strap for double security. Foot straps on pedals are to secure the feet while operating the bike. Derailer levers are on opposite sides of the handlebars. There are two per side: one for the front derailer and another for the rear derailer. The righ t hand controls the left-hand side derailers and the left hand controls the right-hand side derailers. The frame is constructed from medium grade metals that weld together easily. Metals like aluminum and titanium alloys will make for lighter and strong er frames.

Title: Method and apparatus for toughening metal strap buckles
Inventor: BARKLEY RICHARD AARON
IPC: B65D63/16
Filed: 2000-03-28
Abstract: The invention relates to a metal tie buckle made from a single piece of rounded wire that has been bent into a predetermined configuration, wherein two pairs of strap engaging arms that are essentially parallel to one another are provided for securing the buckle to the strap. The buckle has been treated with a hardening process, such as carburizing, carbonitriding, nitriding and induction hardening, that strengthens and toughens the buckle. This helps to keep the arms parallel and prevents the propensity of the buckle to achieve plastic deformation, which in turn helps to prevent the strap from being pinched, or otherwise causing uneven stress on the strap, which could result in premature failure of the strap.

Abstract: A method comprises A: dividing an original curved surface (S) into at most six curved-surface units by combinations of signs (+, 0, -) of the principal curvature (k1, k2) at points on the original curved surface (S), B: dividing a changed curved surface (S') into curved-surface units having the same boundaries in such a way as to correspond to the original curved surface (S), C: finding average normal vectors of the curved-surface units of the original and changed curved surfaces, D: finding the "warp" components and "twist" components of all the combinations of pairs of different curved-surface units of the original and changed curved surfaces, and E: finding the differences between the "warp" and "twist" components of the combinations of the original curved surface and those of the combinations of the changed curved surface. Thus the overall shapes and errors of the original and changed curved surfaces after forming such as CAD data are readily and objectively compared, and the overall shape of a free curved surface is evaluated without being influenced by local "wrinkles" and "cavities". The numerical calculation of this method is easy, and the method is hardly influenced by numerical error and measurement error and applicable even to parametric curved surface and point group.
