Patent number: 11802057Abstract: A sensor system for swimming pools and spas is detailed herein. The sensor system can include one or more sensors positioned in a sensor housing located within a cavity of a pipe and in-line with an inlet and an outlet of the pipe. The sensor housing can divert a portion of water flowing through the cavity to an interior of the sensor housing and to an area around the sensors and maintain at least some of the diverted water in the area around the sensors even if the water is not flowing through or is drained from the pipe.Type: GrantFiled: September 16, 2021Date of Patent: October 31, 2023Assignee: ZODIAC POOL SYSTEMS LLCInventors: Hwa Heng, Ricky Lo, Anthony Levacque

Patent number: 11800623Abstract: A light controller for pool lighting systems is detailed herein. The light controller can include a switch mechanism for controlling light settings of a lighting device. Switch positions of the switch mechanism can each correspond to a different light program. When a switch is positioned at one of the switch positions, the light controller can display one or more corresponding light settings of the light program corresponding to the switch position. A user may select a light setting for the pool lighting systems based on the displayed light settings. In response to the light setting being selected, the lighting device can cause the pool lighting systems to output the selected light setting of the light program.Type: GrantFiled: August 25, 2021Date of Patent: October 24, 2023Assignee: ZODIAC POOL SYSTEMS LLCInventors: Jared Leander, Hwa Heng
