A terminal product usable time management system includes a remote server and a local apparatus. The local apparatus includes a data memory storing an identifier and an encrypted usable time of the terminal product, a microprocessor used to send a start notification of a usable time management process, a product controller used to control a product load, and a wireless networking device used to communicate with the remote server to receive a new expiry date to update the usable time. The usable time management process includes: reading the encrypted usable time stored in the data memory, decrypting the encrypted usable time, decreasing the usable time per time unit, encrypting the decreased usable time, storing the encrypted and decreased usable time into the data memory, and instructing the product controller to disable some or all functions of the terminal product, if the usable time is inaccessible or decreased to zero.

An induction heating system for a basin of a pedicure chair and a pedicure chair with one or more pumps and one or more heating sources are disclosed. A conducting object is located on an interior side of a first wall of the basin, with an induction heater located on the exterior side of the first wall. The conducting object is separated from the induction heater by a solid portion of the first wall. The induction heater is configured to generate a high frequency field that passes through the solid portion of the first wall and causes the conducting object to generate heat. A controller is configured to turn on/off the induction heater to maintain a desired temperature in the basin.

An agent analysis system includes a terminal product system, a remote diagnosis system (RDS), and an agent analyzer. The terminal product system is supplied with a power source and provided with a current sensor to sense the power source. The RDS is used to transmit at least one control instruction via internet for the terminal product system. They agent analyzer is used to communicate with the terminal product system and the RDS, and configured to measure and analyze the electricity use characteristics of the terminal product system to be transmitted to the RDS; and receive and convert the control instruction from the RDS via internet for the terminal product system.

A spa is provided including a frame, a shell mounted to the frame defining a basin for holding water, at least one sensor for monitoring a spa component or water condition, a communications interface including a cellular transceiver, and a battery for providing power to the at least one sensor and to the communications interface when the spa is not connected to a power source. The spa also includes a controller in electrical communication with the at least one sensor and the communications interface. The controller is configured to, while the spa is not connected to the power source, receive information from the at least one sensor, process the received information, and cause the communications interface to wirelessly transmit the processed information to a remote source or central server.

A pedicure chair with a basin for receiving a quantity of water therein. An autofill system can be incorporated with the basin to automatically manage spillover. The auto fill system can have a controller, a water supply valve, and a water level sensor. The water level sensor can be a proximity sensor attached externally of the basin. The water level sensor can send a signal to a controller when the water level sensor detects a predetermined water level in the basin. The controller is configured to shut off the water supply to the basin by sending a signal to actuate the water supply valve. A steamer can be used with the pedicure chair to provide heat and a therapeutic steam bath.

A pedicure chair with a basin having an auto-fill system for depositing water into the basin while eliminating spillover is disclosed. The auto-fill system has a controller, a water supply valve, and a water level sensor. The water level sensor can be a proximity sensor attached to an external surface of the basin. The water level sensor can send a signal to a controller when the water level sensor detects a predetermined water level in the basin. The controller can be configured to shut on and off the water supply to the basin by sending a signal to actuate the water supply valve.

A bath system comprises a tub and a fluid injection system. The tub has a jet orifice, and the fluid injection system is fluidly coupled to the jet orifice. The fluid injection system comprises a conduit, a heat source, an air supply source, and a fluid injector. The conduit has an opening. The heat source is coupled to an outer portion of the conduit external to the opening. The air supply source is fluidly coupled to the conduit, and is configured to provide a flow of air to the central opening. The fluid injector is configured to provide water to the flow of air to produce a combined flow of air and water. The heat source and the conduit are cooperatively configured to heat the combined flow of air and water in the opening before the combined flow enters the tub through the jet orifice.

An irrigation system for use with a spa includes a water heating circuit, an automatic water fill valve connected to a water source, and an irrigation pump in fluid communication with the spa through a first irrigation line and electrically connected to a power source through a switch arrangement. The irrigation pump is adapted to pump water to at least one irrigation head. The automatic water fill valve then refills the spa from the water source. The system may include a fertilizer injector, a skin-product injector, a water softener, and various sensors running through an irrigation application on a smart phone to control the irrigation system and operation of the spa. The system may be installed
