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: 11432947Abstract: A prosthetic ankle has an ankle joint body (10A) constituting a shin component and a foot component (12). The ankle joint body (10A) is pivotally connected to the foot component (12) by a first pivotal connection (14) defining a medial-lateral ankle joint flexion axis. The ankle joint body (10A) also forms the cylinder of an ankle joint piston and cylinder assembly with a superior-inferior central axis, the cylinder housing a piston (16) with upper and lower piston rods (16A, 16B). The lower piston rod (16B) is pivotally connected to the foot component (12) at a second pivotal connection (18). As the ankle joint body (10A) pivots about the ankle joint flexion axis, the piston (16) moves substantially linearly in the cylinder formed by the ankle joint body. The cylinder is divided into upper and lower chambers (20A, 20B).Type: GrantFiled: July 3, 2018Date of Patent: September 6, 2022Assignee: Blatchford Products LimitedInventors: Mir Saeed Zahedi, Graham Harris, Stephen Terry Lang, Robert Michael Andrew Painter, David Moser

Patent number: 9942878Abstract: A method and apparatus for selecting a TFC in a wireless transmit/receive unit (WTRU) is disclosed. The WTRU estimates a transmit power for each of a plurality of available transport format combinations (TFCs). A TFC is selected for an uplink dedicated channel and a TFC is selected for an enhanced uplink (EU) channel. The TFC for the dedicated channel is selected first and independently of the TFC selection of the EU channel. The TFC for the EU channel is selected within a remaining WTRU transmit power after the TFC selection for the dedicated channel.Type: GrantFiled: October 9, 2014Date of Patent: April 10, 2018Assignee: INTEL CORPORATIONInventors: Guodong Zhang, Stephen Terry, Stephen Dick

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
