Title: Motion apparatus
Inventor: MITCHELL ANDREW JOHN
IPC: A63B22/02
Filed: 1997-03-20
Abstract: An omni-directional treadmill providing a surface with no gaps on which a user can move. The treadmill is generated by arranging a set of looped belts (1, 2, 10), each providing at least one elongated surface, abutting one another along the elongate edges provided by the elongate surface. A group of these elongate surfaces defines the treadmill surface. This set of belts (1, 2, 10) is itself arranged in a loop. Movement of the whole set of belts around this loop moves the treadmill surface in one direction. Simultaneous rotation of all the belts (1, 2, 10) providing the surface provides movement perpendicular to the first direction. Using these two components of motion the treadmill can move in any direction indefinetly. Feedback from user can be used to move the treadmill in the opposite direction to keep user in the same place, in the same way a treadmill maintains user moving in one direction in the same place.

Patent CA-2255281-A1 (CA)
Inventor: PEDERSEN PETER
IPC: D04B1/10
Filed: 1998-12-03
Abstract: For the production of colour patterned knitwear products of the sweater type it is customary to use the same type of yarn, only coloured differently. With the invention, use is made of different yarns of natural materials with their associated characteristic natural colours, as it is a purpose to entirely avoid artificially coloured yarns. The different sub areas, consisting e.g. of cotton, silk and flax, will then exhibit different physical properties, e.g. with respect to rigidity and body friendliness, and in order to outbalance these differences the sub areas are provided with a platination at their inner sides consisting of a compensating mesh layer of a relevant natural yarn, e.g. a cotton or silk layer for making a flax area more body friendly or a cotton layer for mechanically stabilizing a slack silk area. In practice, a cotton layer is well suited as an overall platination layer.

Title: Electronic verification machine for documents
Inventor: DAIGLE STEVEN J
IPC: G07D7/00
Filed: 1999-09-30
Abstract: Determination of the authenticity and integrity of various types of documents such as lottery tickets is accomplished by using an electronic verification machine to compare data contained in electronic circuits printed on the document to document data printed on the document. The electronic circuits are printed on the document in conductive or semiconductive ink using, for example, the gravure printing process, and the presence and status of the circuits can be used to verify or authenticate the document. Data can be represented in the electronic circuits by the electrical signature of the circuit which is measured by the electronic verification machine. In the case of lottery tickets, a ticket can be validated by having the electronic verification machine determine which play spots have been removed from the ticket and comparing data on the ticket with the removed play spots to determine a play redemption value for the ticket. Document verification or lottery ticket validation can also be accomplished by transmitting signature data from the electronic circuits via the electronic verification machine to a central computer for comparison with document data.
