  • Publication number: 20190328612
    Abstract: 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.

  • Patent number: 8624550
    Abstract: An adapter for providing a source of power to a mobile device through an industry standard port is provided. In accordance with one aspect of the invention, the adapter comprises a plug unit, a power converter, a primary connector, and an identification subsystem. The plug unit is operative to couple the adapter to a power socket and operative to receive energy from the power socket. The power converter is electrically coupled to the plug unit and is operable to regulate the received energy from the power socket and to output a power requirement to the mobile device. The primary connector is electrically coupled to the power converter and is operative to couple to the mobile device and to deliver the outputted power requirement to the mobile device. The identification subsystem is electrically coupled to the primary connector and is operative to provide an identification signal.

  • Patent number: 8363370
    Abstract: An over-voltage protection circuit is disclosed herein for protection against over-voltage of an energy storage device while charging. The circuit operates within the operational limits of a battery-operated device, such as a mobile or handheld device. The over-voltage protection circuit comprises an over-voltage protection device, and an over-voltage protection controller. The controller allows current to flow to the over-voltage protection device only when an energy storage device is experiencing over-voltage. In allowing current to flow to the over-voltage protection device only when the voltage across the energy storage device is above a predetermined voltage, power conservation is achieved.
