Abstract: One particular implementation of the present invention may involve a control unit of an ionic foot bath or other health product. The control unit may be connected to a network or the Internet such that the control unit may be monitored or controlled by a third party, such that the third party may provide programming updates, adjust the programming of the control unit to conform to the user's preferences and provide flexibility to a practitioner with several foot bath systems. The control unit may also provide the functionality of a pay-per-use method for use of the ionic foot bath. The method may allow a user or an operator of the product to purchase operational time that is desired to use the product. Once the operating time is purchased, the product may be operated for the purchased amount of time, at which point, more usage time may be purchased.

Abstract: A method for replacing an ionizer unit of a therapeutic spa system may include removing a fastener that joins a first plate of a frame assembly to a second plate of the frame assembly. The first plate may be spaced apart from and substantially parallel to the second plate when joined to the second plate by the fastener. The method may further include detaching the first plate and the second plate of the frame assembly from a first ionizer unit supported by the first and second plates, joining a second ionizer unit to the first and second plates, and rejoining the first and second plates with the fastener.
