| 20090100590 | Basin for a foot spa - A spa device including a basin with at least one agitation device and at least one foot massaging device. The agitation device is a pipeless fluid jet. The massaging device may be a three piece massaging foot roller which is placed in a cavity in the bottom surface of the basin. The spa device may include electronic controls for controlling the fluid and agitation devices. The spa device electronic control system may include a fluid level sensor. When the fluid level in the basin reaches a predetermined high level the control system turns off the fluid. When the fluid level in the basin reaches a predetermined low level the control system turns off the jets. | 04-23-2009 |
| 20100017954 | VARIABLE MOTOR DRIVE SYSTEM FOR A RESERVOIR WITH CIRCULATING FLUID - A motor drive for an electric motor of a variable fluid circulating system includes a processing module and a power module. The processing module receives a signal profile and generates a control signal based on the signal profile. A power module generates a carrier signal based on the control signal and a direct current (DC) voltage. The power module pulse width modulates the carrier signal to generate a drive signal in the electric motor that matches the signal profile. The power module powers the electric motor based on the drive signal to adjust injection of a fluid into a reservoir. | 01-28-2010 |
| 20110225721 | Freeze Prevention for a Spa Having a Spa Pack Powered Through a Ground Fault Circuit Interrupter - Systems and methods for preventing water from freezing in a spa or hot tub featuring a spa pack having a pump, heater and controller connected to a spa power supply through a ground fault circuit interrupter. A sensor is used to monitor an operating condition of the spa pack that is initially electrically connected to the spa power supply in order to activate at least one freeze prevention device if the operating condition of the spa pack changes due to electrical disconnection from the spa power supply by the ground fault circuit interrupter. The freeze prevention device features a heater, a circulating pump or both, and keeps water in the tub and the piping associated therewith from freezing. A switching arrangement is provided for deactivating the system outside the winter season when freeze protection is not required. | 09-22-2011 |
| 20130160200 | Constant Temperature Tub (CTT) - This is a device and method to keep the temperature of the water in a bathtub at constant temperature throughout the duration of its use. The invention runs off of the electricity supplied to a home. It provides a system that conserves water and energy. The invention only replaces the energy lost to the environment and recycles the water. | 06-27-2013 |
| 20130340158 | WATER INGRESS DETECTION SYSTEM - A detection system for a tub having a water recirculation system includes an electronic sensor and an indicator. The electronic sensor is configured to detect a condition indicative of water being present in a water recirculation system of a tub. The indicator is configured to provide a visual indication according to the detected condition. | 12-26-2013 |
| 20150033466 | RESISTIVE ACTUATION UNIT FOR TUB SYSTEMS - A tub comprising a body for holding a volume of water. A tub system is coupled to the body to perform a function on the volume of water. At least a first circuit has a first circuit portion comprising at least one resistive switch mounted to a visible surface of the body and comprising at least a first resistive element adapted to be contacted by a bather, second circuit portion comprising a water detection sensor mounted to the body for containing liquid in the body above a given level, the first circuit being open between the first resistive element and the water detection sensor, an actuating closed circuit condition by which a bather in liquid above the given level closes the first circuit between the first circuit portion and the second circuit portion when touching the first resistive element. A controller is operationally coupled to first circuit portion and the second circuit portion of the first circuit, and to the tub system, the controller adapted to detect the actuating closed circuit condition to trigger an action of the tub system. | 02-05-2015 |
