Patent number: 11679008Abstract: A self-aligning prosthetic foot and ankle assembly has an ankle unit pivotally mounting a foot component. The ankle unit contains a hydraulic piston and cylinder assembly having a piston which is linearly movable within a cylinder. The axis of the cylinder is coincident with a shin axis defined by a shin connection interface on the ankle unit. Bypass passages containing damping resistance control valves provide continuous hydraulic damping of dorsi and plantar ankle flexion, the unit being such that, over the major part of the range of damped movement, there is no resilient biasing in either the dorsi or the plantar direction. This confers a number of advantages, including stabilisation of standing, balance control, and improved stair-walking and ramp-walking.Type: GrantFiled: June 18, 2018Date of Patent: June 20, 2023Assignee: Blatchford Products LimitedInventors: David Moser, Fadi Abimosleh, Mir Saeed Zahedi, Graham Harris, Stephen Terry Lang, Andrew John Sykes

Patent number: 11529246Abstract: A prosthetic ankle and foot combination has an ankle joint mechanism constructed to allow damped rotational movement of a foot component relative to a shin component. The mechanism provides a continuous hydraulically damped range of ankle motion during walking with dynamically variable damping resistances, and with independent variation of damping resistances in the plantar-flexion and dorsi-flexion directions. An electronic control system coupled to the ankle joint mechanism includes at least one sensor for generating signals indicative of a kinetic or kinematic parameter of locomotion, the mechanism and the control system being arranged such that the damping resistances effective over the range of motion of the ankle are adapted automatically in response to such signals. Single and dual piston hydraulic damping arrangements are disclosed, including arrangements allowing independent heel-height adjustment.Type: GrantFiled: November 9, 2018Date of Patent: December 20, 2022Assignee: Blatchford Products LimitedInventors: David Moser, Andrew John Sykes, Graham Harris, Stephen Terry Lang, Fadi Abimosleh, Mir Saeed Zahedi

Patent number: 9433513Abstract: A prosthetic foot and ankle assembly includes a foot component and an ankle joint mounted thereto and having a fixed range of dorsi-plantar flexion. The ankle joint includes a joint mechanism in the form of a hydraulic linear piston and cylinder assembly having a pair of chambers on opposite sides of the piston to provide hydraulic damping continuously over the range of dorsi-plantar flexion. The joint mechanism further includes a valve arrangement controlling the flow of hydraulic fluid between the chambers. The valve arrangement includes first and second adjustable valves for independently controlling dorsi-flexion damping resistance and plantar-flexion damping resistance respectively. The joint mechanism includes a first flexion limiter that limits dorsi-flexion of the joint mechanism to a dorsi-flexion limit and a second flexion limiter that limits plantar-flexion of the joint mechanism to a plantar-flexion limit, thereby defining the fixed range of dorsi-plantar flexion.Type: GrantFiled: October 11, 2013Date of Patent: September 6, 2016Assignee: Blatchford Products LimitedInventors: David Moser, Fadi Abimosleh, Mir Saeed Zahedi, Graham Harris, Stephen Terry Lang, Andrew John Sykes

Patent number: 9170189Abstract: A testing apparatus for testing the strength of a material connection to a substrate. A drive mechanism couples a test tool mount to a main body and allows for relative movement between the test tool mount and the main body in an axial direction. A biasing element is coupled between the main body and the test tool mount, that, in operation, biases the test tool mount relative to the main body in an axial direction. The biasing element is switchable between a first state in which the test tool mount is biased either toward or away from the substrate and another state in which the biasing element provides one of: no biasing force to the test tool mount toward or away from the substrate, or a biasing force in a direction opposite to the direction of bias applied in the first state.Type: GrantFiled: March 25, 2014Date of Patent: October 27, 2015Assignee: Nordson CorporationInventors: David Lilley, Martin Bugg, Robert John Sykes

Patent number: 9132023Abstract: A prosthetic ankle and foot combination has an ankle joint mechanism constructed to allow damped rotational movement of a foot component relative to a shin component. The mechanism provides a continuous hydraulically damped range of ankle motion during walking with dynamically variable damping resistances, and with independent variation of damping resistances in the plantar-flexion and dorsi-flexion directions. The mechanism also provides for adjustment of a second piston element with respect to a shin component when a first valve is closed and a locking valve is open to adjust a reference angular position independently of the damping function that occurs during walking.Type: GrantFiled: June 1, 2011Date of Patent: September 15, 2015Assignee: Blatchford Products LimitedInventors: David Moser, Fadi Abimosleh, Mir Saeed Zahedi, Graham Harris, Stephen Terry Lang, Andrew John Sykes
