Appl. No.:

09/823362

Inventors:

John Arthur Ohrt - Redmond WA
James A. Duncan - Renton WA

Assignee:

Nautilus, Inc. - Vancouver WA

International Classification:

A63B 6916

US Classification:

482 52, 482 57, 482 70

Abstract:

An exercise device providing a fore and aft horizontal component of striding motion that is dynamically user-defined, while providing a vertical component of the motion that is maintained on a predetermined vertically reciprocating path in some embodiments. The exercise device guides the users foot in a pseudo-elliptical stride path, while providing a dynamically variable stride length that allows the user to move with a natural stride length. The exercise device allows tall and short users to extend or curtail the stride length to match their natural stride lengths. The length of the reciprocating path is dynamically adjusted during the exercise operation without equipment adjustments by changes in the length of the stride input by the user at a pair of foot engagement pads disposed on laterally spaced apart foot support members.

International Classification:

B65G 53/58

US Classification:

406 84, 406191

Abstract:

A device for transporting articles is disclosed. In the illustrated and described embodiment of the invention, the articles are fruit such as apples, and the articles can be transported from a picking location on a fruit tree to a collection bin or other site. The device includes a tube member adapted to receive and transport the articles, and a plurality of deformable baffles at spaced-apart locations within the tube. Each baffle defines an aperture which permits the article to engage and deform the baffle and aperture so as to create at least a partial momentary seal to encourage article movement through the aperture and down the tube. The article is urged through the tube by a pressure differential created across the article. In the described and illustrated embodiment of the invention, this pressure differential is a pneumatic pressure differential. The tube and the baffle apertures can have non-circular cross-sectional shapes.

US Classification:

606247, 606257, 606265

Abstract:

The invention discloses methods, devices, systems and kits for repairing, replacing and/or augmenting natural facet joint surfaces and/or facet capsules. An implantable facet joint device of one embodiment comprises a cephalad facet joint element and a caudal facet joint element. The cephalad facet joint element includes a member adapted to engage a first vertebra, and an artificial cephalad bearing member. The caudal facet joint element includes a connector adapted for fixation to a second vertebra at a fixation point and an artificial caudal bearing member adapted to engage the cephalad bearing member. The artificial caudal bearing member is adapted for a location lateral to the fixation point.
