Patent number: 11484979Abstract: A precision tripod motion system is provided. The tripod motion system in one example includes a bottom plate including three spaced-apart bottom single-degree-of-freedom hinges, a top plate including three spaced-apart top three-degrees-of-freedom (TDOF) joints, wherein the top plate is configured to receive a workpiece. Each linear actuator of three linear actuators is coupled to an associated SDOF hinge of the bottom plate and coupled to an associated TDOF joint of the top plate. Each linear actuator is configured to change length over a linear actuation span and configured to return the top plate to a predetermined set position after the top plate is displaced by an external force Each linear actuator includes a ball coupled to the associated three TDOF joint and a positioning actuator configured to move the ball to the predetermined set position prior to the return of the top plate to the predetermined set position.Type: GrantFiled: June 26, 2017Date of Patent: November 1, 2022Assignee: ALIO INDUSTRIES, INC.Inventors: Nathan Lyons Brown, Clement William Hennessey, Daniel Fording Crews

Patent number: 10695702Abstract: Blood separation media include a fibrous web formed by 50 to 99 parts by weight of glass microfibers, and 1 to 50 parts by weight of fibrillated fibers; a polymeric, hydrophilic binder; a wetting agent; and a salt. The binder covers at least a part of the glass microfibers, and the web is further impregnated with a wetting agent and it contains a salt which is capable of crenating red blood cells. The pore size of the media is smaller than the average pore size of red blood cells. Compared to conventional separation media, the invention will improve efficiency of the separation of the red blood cells from the plasma and increase the speed and volume of the separated material. The present invention also provides for a decrease in lysing of the red blood cells during the filtration process which gives improved purity of the material.Type: GrantFiled: July 25, 2016Date of Patent: June 30, 2020Assignee: AHLSTROM-MUNKSJÖ OYJInventor: William Hennessey
