  • Publication number: 20190192379
    Abstract: A massage chair includes a frame having a base frame and a backrest frame. The backrest frame pivotally couples to the base frame and operates between at least two positions. The backrest frame has a mechanical rotating joint and guide rail. The guide rail splits at the rotating joint when transitioning positions. An extendable footrest frame is included and pivots relative to the backrest frame. A foot massage airbag system includes a plurality of airbags coupled to the extendable footrest frame. An electronic circuit board has an embedded software program for regulating the position of the backrest frame and the footrest frame. Additionally, the electronic circuit board communicates with a compressor and valve to regulate operation of the airbags. Operation of the airbags induces a stretching effect upon a user as the airbags inflate to compress against the user and the extendable footrest frame extends.

  • Patent number: 10302088
    Abstract: A pump having a contactless, fluid sensor for dispensing a fluid to a setting and for use with a liner is disclosed. The pump includes a jet assembly, a motor assembly, and a contactless, fluid sensor. The pump may further include a mounting housing member, a gasket or seal, and a liner when a liner is not already present. The jet assembly is secured to or about the motor assembly. The jet assembly includes a jet assembly housing, and preferably also includes a printed circuit board (PCB), a PCB cover, a shaft assembly, and an impeller. The jet assembly housing includes a base, a top cover, an impeller-receiving chamber, at least one inlet aperture, and at least one outlet aperture. The present invention is also directed to a pump apparatus that includes a pump as described, a power source, and/or a control apparatus.

  • Patent number: 10288071
    Abstract: An improved bearing and shaft assembly includes a bearing assembly having an outer bearing member and an inner bearing member, and a shaft assembly having a shaft member, a shaft protection member, and a locking mechanism. The outer bearing member has a cavity for receiving the inner bearing member, and fits within a cavity of an impeller. The shaft assembly is secured within a housing of a jet assembly. The shaft protection member has a cavity for receiving the shaft member. The shaft protection member fits within the cavity of the inner bearing member. Also, a jet assembly, which includes the improved bearing and shaft assembly, may be coupled to a motor assembly. The jet assembly further includes the housing that includes at least one inlet aperture and at least one outlet aperture, and an impeller positioned within a cavity of the housing.

  • Patent number: 10278894
    Abstract: The present invention is directed to a jet assembly comprising a jet assembly housing, a magnetic impeller, and at least one friction-reducing member. The present invention is also directed to a fluid pump that comprises a motor assembly and a jet assembly comprising a jet assembly housing, a magnetic impeller, and at least one friction-reducing member. The present invention is further directed to a method for dispensing a fluid using the jet assembly comprising a jet assembly housing, a magnetic impeller, and at least one friction-reducing member. The at least one friction-reducing member allows a motor assembly to cause a magnetic impeller to rotate within a jet assembly housing and preferably not make contact with an inner surface of a back cover of the jet assembly housing during operation of the jet assembly such that a shaft member(s) and/or a bearing(s) is/are not required for rotation of the magnetic impeller.
