International Classification:

G06F017/60

US Classification:

705 8, 705 28

Abstract:

A demand fulfillment system and method to provide current supply and demand to generate a work schedule and a material delivery schedule for manufacturing items, particularly commodities, built to customer order. The demand fulfillment system and method uses outstanding customer orders for items as an accurate measure of current demand, and a current state of an available inventory of material for producing the items as an accurate measure of current supply. Customer orders are considered a source of demand from the time the customer order is received until the customer order is fulfilled. Material available to the factory is considered to be part of supply regardless of location of the material. A work schedule and a material delivery schedule are generated periodically using the current state of the available inventory and outstanding customer orders to keep up with consumption of materials and fulfillment of customer orders.

International Classification:

A61F 2/42

US Classification:

623 2118

Abstract:

Implant devices, and method of using the same, are provided. The implant devices have a head and a stem. The head has an upper surface, an anterior surface, a posterior surface, a lateral surface and a lower surface. The anterior surface, the lateral surface, and the lower surface are approximately perpendicular to and intersect each other. The anterior surface and the posterior surface are approximately parallel to each other. Preferably, the upper surface has a general shape of at least a portion of a superior articular surface of a talus and at least a portion of a medial articular surfaces of a talus. The stem has a truncated conical portion and a cylindrical portion. The cylindrical portion is affixed to the lower surface of the head, and the truncated conical portion is affixed to the cylindrical portion.

A61F 2/28

US Classification:

623 1412, 623 1611, 623 1811

Abstract:

Cartilage implant devices having oval articular ends are provided. The articular ends have a convex upper face and a concave lower face. The convex upper face has a first circular pitch radius and a first circular roll radius. The concave lower face has a first surface comprising a second circular pitch radius and a second circular roll radius, and at least two second surfaces each second surface having a third circular pitch radius and a third circular roll radius. The convex upper face blends into a rim, wherein at least a first and second portion of the rim extends at least a first distance along the vertical axis and a third and fourth portion of the rim tapers inward along the vertical axis, the rim blends into the concave lower face. The implant devices further have a stem extending from the concave lower face away from the convex upper face.

US Classification:

623 1412, 623 1611, 623908, 623 2351

Abstract:

Methods of using cartilage implant devices are provided. The methods include locating articular cartilage having a lesion, and utilizing an implant having dimensions compatible with the lesion. The method further includes forming a cavity in the articular cartilage, subchondral bone, and cancellous bond, and engaging the implant with the cavity so that the lower face of the articular end of the implant abuts against the subchondral bone, and the stem of the implant abuts against the cancellous bone.

US Classification:

623 1412, 623 1811, 623 2344

Abstract:

Implant devices, and method of using the same, are provided. The implant devices have circular, or oblong, articular ends. The articular ends have a convex upper face and a concave lower face, the convex upper face blending to the concave lower face, and the concave lower face having a curvature less than the curvature of the convex upper face. The implant devices further have a stem extending from the concave lower face away from the upper face, the stem having a maximum radius at the convex lower face and tapering to lesser radius along the length of the stem.
