  • Publication number: 20230226773
    Abstract: A method of constructing an inflatable fluidic actuator. The method includes coupling a first interface to a tube configuration of membrane material at a first tube end by coupling the first interface to the tube configuration at the first tube end by generating at least one of: a first bond between the membrane material and one or more first sidewalls of the first interface and a first external face bond between membrane material at the first tube end onto a first external face of the first interface.
    Type: Application

  • Patent number: 11642857
    Abstract: A method of constructing an inflatable fluidic actuator that includes generating a tube configuration with one or more shapes of fluid-impermeable membrane material, the tube configuration having a first tube end and a second tube end and an internal tube face and an external tube face. The method also includes coupling a first and second interface to the tube configuration at the first and second tube ends by respectively coupling each interface to the tube configuration at a respective tube end by generating at least one of: a first circumferential bond between the fluid-impermeable membrane material and one or more sidewalls of the interface; and an external face bond between fluid-impermeable membrane material at the tube end onto an external face of the interface.

  • Publication number: 20210259904
    Abstract: An exoskeleton system comprising an inflatable actuator configured to be worn by a user. The inflatable actuator includes a fluid-impermeable member that defines a fluid chamber at least in part by a membrane material and a first and second interface that each define sidewalls, the membrane material is coupled to the sidewalls of the first and second interfaces.

  • Publication number: 20200282253
    Abstract: A lightweight trampoline enclosure system has a bed subsystem and an enclosure subsystem. The enclosure subsystem comprises netting suspended from a plurality of flexible poles. Upon a jumper's impact into the surrounding enclosure subsystem, the energy of the jumper's impact is absorbed and distributed outward and away from the location of impact and into the trampoline bed subsystem.
