  • Patent number: 12034292
    Abstract: A power conversion circuit having a solid-state circuit breaker integrated therein is disclosed. With a disconnect switch between a utility source and the power conversion apparatus described for meeting UL489, the power conversion circuit includes an input connectable to an AC source, a rectifier circuit connected to the input to convert an AC power input to a DC power, and a DC link coupled to the rectifier circuit to receive the DC power therefrom. The rectifier circuit comprises a plurality of phase legs each including thereon an upper switching unit and a lower switching unit, wherein at least one of the upper and lower switching units on each phase leg comprises a bi-directional switching unit that selectively controls current and withstands voltage in both directions, so as to provide a circuit breaking capability that selectively interrupts current flow through the rectifier circuit, while maintaining original power conversion functionalities.

  • Publication number: 20210401592
    Abstract: In some examples, a prosthesis system comprises a socket housing comprising a socket configured to receive a residual limb of a wearer. The socket housing further comprising a pylon extending distally of the socket. The socket housing further comprising a first interlock structure at a distal end of the pylon where the first interlock structure comprises a first one or more programmed magnets. The prosthesis system further comprising an extremity unit configured to be attached to and removed from the pylon where the extremity unit comprises a second interlock structure comprising a second one or more programmed magnets. The pylon and the extremity unit are configured such that, when the extremity unit is attached to the pylon, the first and second one or more programmed magnets are positioned and oriented to magnetically attract each other and secure the extremity unit to the pylon.

  • Publication number: 20210378844
    Abstract: In one example of the present disclosure, a system may be configured with a prosthetic liner configured to be worn over a residual limb of a user where the prosthetic liner comprises a first one or more programmed magnets. The system may be further configured with a prosthesis comprising a prosthetic socket configured to receive the residual limb and the prosthetic liner where the prosthetic socket comprises a second one or more programmed magnets. The first one or more programmed magnets are magnetically attracted to and repelled by corresponding ones of the second one or more programmed magnets when the prosthetic liner is received within the prosthetic socket.
