Publication number: 20240134341Abstract: The present application relates to systems and methods for obtaining real-time abrasion data. An example computer-implemented method could include receiving, at a computing device, sensor data from one or more sensors. The one or more sensors are disposed in proximity to an abrasive product or a workpiece associated with the abrasive product. The one or more sensors are configured to collect abrasion operational data associated with an abrasive operation involving the abrasive product or the workpiece. The computer-implemented method could further include training, based on the sensor data, a machine learning system to determine product specific information of the abrasive product and/or workpiece specific information. The computer-implemented method could also include providing the trained machine learning system using the computing device.Type: ApplicationFiled: May 31, 2022Publication date: April 25, 2024Inventors: Sujatha K.

Patent number: 6863695Abstract: A prosthetic foot includes an adapter element securable to a residual limb, a foot plate having a heel portion and a toe portion along the length thereof, at least one toe spring connected between the adapter element and the toe portion of the foot plate, and a heel spring connected between the adapter element and the heel portion. The heel spring may be a leaf spring or a tube type shock absorber. The concave side of the leaf spring exhibits a plurality of transverse ribs. Alternatively, a tubular pylon may have a collar mounted thereon for movement along the length of the pylon. A toe spring and a heel spring extend from the collar to form toe and heel portions of the prosthetic foot. A further heel spring is connected between the heel portion and another end of the pylon, and a non-extensible band extends between the heel portion and the collar. As another alternative, a tubular pylon has one end securable to a residual limb, and a collar is mounted to the pylon for movement along the length of the pylon.Type: GrantFiled: January 29, 2003Date of Patent: March 8, 2005Assignee: Ohio Willow Wood CompanyInventors: Jeffrey L. Doddroe, Robert E. Arbogast, James M. Colvin, James W. Capper, Sujatha Srinivasan

Patent number: 6290730Abstract: An artificial foot and ankle is provided having a keel component, an ankle component, and a central bumper component interposed between the keel component and the ankle component. The ankle component has a lower surface with a radius of curvature greater than the radius of curvature of an upper surface of the keel component in both a sagittal plane and a frontal plane. The curvature of the central bumper component corresponds to the curvature of the keel component. A holding assembly holds the keel component, the ankle component, and the central bumper component together, with the ankle component capable of rolling motion relative to the keel component in both the sagittal plane and the frontal plane. A dorsiflexion stop assembly may also be provided to control the amount of dorsiflexion.Type: GrantFiled: March 16, 2000Date of Patent: September 18, 2001Assignee: Ohio Willow Wood CompanyInventors: Mark R.

Patent number: 5800567Abstract: A knee mechanism for a lower limb prosthesis which maintains knee stability over an initial range of flexion and includes an upper member for connection to or forming part of the thigh component of a prosthesis, a lower member for connection to or forming part of the shin component of a prosthesis, and a slider and a crank connecting the upper member to the lower member. The locus of the instantaneous center of rotation of the mechanism is a curve which commences above the knee and posterior to the load line and which, over an initial range of flexion of the mechanism, moves continuously downwards and to the posterior, the curve being convex towards the posterior. The lower member, the slider and the crank preferably constitute a slider crank mechanism with the crank pivotally connected to the upper and lower members and the slider pivotally connected to the lower member and slidably connected to the upper member.Type: GrantFiled: March 10, 1997Date of Patent: September 1, 1998Assignee: Ohio Willow Wood CompanyInventors: John Edwin Cooper, Robert E.

Patent number: 5800563Abstract: An impact reducing prosthetic pylon has a distal component which can be attached to a prosthetic foot and includes a housing within which the proximal component can slidably fit. A resilient bumper-like member formed of a foam is positioned within the housing and is compressed by the proximal component when the prosthesis is under a load. Relative rotation of the proximal and distal components is prevented, but a limited, resiliently damped rotation may be permitted.Type: GrantFiled: December 22, 1995Date of Patent: September 1, 1998Assignee: Ohio Willow Wood CompanyInventors: Robert E. Arbogast, Eric K. Bartkus, James M. Colvin, Sujatha Srinivasan
