Publication number: 20060174795Abstract: A mass transit system utilizing buoyant craft intermittently propelled by water jets that are activated when craft are in dose proximity, within interconnected sections of āUā shaped canals/channels that can be pre-manufactured and delivered via heavy truck. Individual craft can be directed by rider via interactive signage along route or if empty by computer via sensors in canal walls. Bar code readers track craft location at all times. Water in canals is recirculated with pumps that pull water from the area just in front of direction of craft movement, thus creating a temporary fast moving forward water motion. Merge points similar to a freeway entrance ramp are made possible by hydraulic wheel guides that are activated when the rider chooses course. Embarking and disembarking stations at various points can be entered or exited without traffic stops. Adjustable safety bar at each seat.Type: ApplicationFiled: February 7, 2005Publication date: August 10, 2006Inventor: John Osborn

Publication number: 20050243074Abstract: A pointing device includes a single control element to provide a user with absolute coordinate information and to enable user control of a computer cursor and emulation of mouse clicks. User movement of the single control element in an (x-y) plane preferably moves an optically reflective surface relative to an optical sensor system stationary within the device housing, such movement precluding rotation relative to the (x-y) plane. Mouse clicking may be emulated by moving the single control element up or down and/or by tilting relative to the (x-y) plane. Alternatively mouse clicking may be emulated by user activation of left and right sensor type switches or sensors. The device may be used by handicapped persons who can control cursor movement and mouse clicking using the single control element.Type: ApplicationFiled: June 30, 2005Publication date: November 3, 2005Inventor: John Osborn

Patent number: 6705582Abstract: An assembly of concrete forms for use in the placement of concrete, the assembly having a pair of longitudinal form members and a ground engaging member that is in contact with at least one of the longitudinal form members. A first longitudinal form member slidably overlaps a second longitudinal form member such that the length of the combination of longitudinal form members is adjustable. Inverted U-shaped channels are provided at the top of each of the longitudinal form members which allow a male/female overlapping relationship and provide a location to receive the ground engaging member. A radius form member includes a longitudinal form member with a horizontal component or inverted U-shaped channel having successively spaced apart slots thereon, so that the radius form member is flexible. To create an angle, a corner forming bar is also provided for the assembly, extending between two of the longitudinal form members.Type: GrantFiled: August 29, 2001Date of Patent: March 16, 2004Inventor: John Osborn
