Patent number: 10912657Abstract: A system for a unicompartmental knee replacement is described. The system can include a femoral prosthesis component, a tibial prosthesis component and a meniscal bearing. The meniscal bearing can be insertable between the femoral prosthesis component and the tibial prosthesis component. The meniscal bearing can include a first bearing surface configured to bear against the femoral prosthesis component, a second bearing surface opposed to the first bearing surface and configured to bear against the tibial prosthesis component, and a sidewall separating the first bearing surface from the second bearing surface, wherein the sidewall has a retention groove formed in a portion thereof, and wherein the meniscal bearing and the tibial prosthesis component are configured such that the retaining flange enters the retention groove on movement of the meniscal bearing relative to the tibial prosthesis component towards the medial wall.Type: GrantFiled: October 23, 2018Date of Patent: February 9, 2021Assignee: Biomet UK LimitedInventors: John Goodfellow, John Joseph O'Connor, Christopher Dodd, David Wycliffe Murray

Patent number: 10590937Abstract: An improved compressed air system utilizes one or more base compressors, such as fixed speed drive compressors, to meet the compressed air demands and one or more trim compressors, such as variable speed drive compressors, to meet the variations in the demand. The operation of both the base and trim compressors may be controlled to provide improved overall efficiency while meeting the transient load demands. The control may spread the demands over the various base compressors to improve the overall loading on each base compressor. Efficiency metrics may be utilized to control the switching between base and trim compressors. Unloading of a base compressor may be controlled to avoid undesirable changes in system performance.Type: GrantFiled: April 12, 2016Date of Patent: March 17, 2020Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: John A. Goodfellow, Jodie S. Mels, Robert J. Coveney

Patent number: 9314742Abstract: The present invention can include a reverse osmosis unit, a control system, a display, and/or a memory. The reverse osmosis unit can include a filtration unit, a liquid utilization system, and/or an instrumentation system. The filtration unit includes a plurality of filter banks which each have a plurality of filter unit. The filtration unit receives a feed liquid and generates permeate and concentrate. The permeate is sent to the liquid utilization system, while the concentrate is removed. The instrumentation system can include a plurality of sensors to detect operational data of the feed liquid, permeate, and/or concentrate. Using the operational data and equations, the control unit can calculate the normalized permeate flow rate indicating whether the filters should be cleaned and/or replaced. The operational data and the equations can be used to determine whether the pressure and/or flow can be manipulated without damaging the filters.Type: GrantFiled: March 31, 2010Date of Patent: April 19, 2016Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventor: John A.
