    Abstract: Systems, methods, and apparatus provide artificial knees. Artificial knees include a thigh link configured to move in unison with a thigh of the person, a shank link configured to be rotatably coupled to said thigh link, and a compression spring rotatably coupled to the thigh link and coupled to a second end of shank link with a second end of the compression spring. During a first range of motion, the compression spring is configured to provide an extension torque between the thigh link and the shank link causing said artificial knee to resist flexion. After said first range of motion, the compression spring is configured to provide a flexion torque between the thigh link and the shank link encouraging said artificial knee to flex resulting in toe clearance during the swing phase. During the swing phase, the compression spring provides no torque between the thigh link and the shank link.

  • Patent number: 10727579
    Abstract: Radio frequency antennas sharing a ground plane are largely decoupled using one or more lumped capacitive elements set into holes within the ground plane. The holes, which are precisely placed, can extend to a side of the ground plane. A stub extends from a fringe of the hole either straight or bending in an L shape, and a capacitor connects between an end of the stub and another side of the hole. Capacitive elements can also be supported on raised solder pads above a ground plane or off to one side of the ground plane. Methods for manufacturing the decoupling apparatus are described.

  • Patent number: 10688707
    Abstract: A system and method for forming fluted polymer boards and recycling scrap material. A feeder feeds polymer to an extruder, which extrudes fluted board stock from the polymer. A scrap portion of the board stock is separated from another portion that comes to form the boards. The recycling system returns the separated scrap portion along a return path to the feeder and forms holes in the scrap portion creating fluid communication between the flutes and atmosphere before the scrap portion is returned to the feeder. The scrap portion can, in some embodiments, be ground into granular form after being hole-punched without creating a pressure condition in the flutes that adversely affects extrusion of the board stock.

  • Publication number: 20200190471
    Abstract: The present invention relates to an in vitro immune synapse system and a method of in vitro evaluating immune response using the same. The in vitro immune synapse system includes antigen-presenting cells (APCs) and at least one cell type of several specific T cell subtypes isolated from peripheral blood mononuclear cells (PBMCs), all of which is from a same individual of pigs. When a test sample is co-cultured in the in vitro immune synapse system for a given period, it can be determined that the test sample is immunogenic, immunostimulatory or not according to the immunization-related changes of these cells, thereby potentially replacing some kinds of animal experimentation.
