SYSTEM AND METHOD FOR IMPROVED INSTALLATION AND CONTROL OF CONCEALED PLUMBING FLUSH VALVES
First Claim
1. A plumbing fixture installation and valve control system comprising:
- a user interface module (UIM) for installation adjacent a plumbing fixture, the UIM module having a UIM high frequency transmitter and a UIM low frequency receiver for communication in an active mode and a learning mode;
a valve interface module (VIM) having a valve interface for operative connection to a valve, the VIM for controlling fluid flow through the valve, the VIM including a VIM high frequency receiver and a VIM low frequency transmitter for communication with the UIM;
wherein the UIM high frequency transmitter, the UIM low frequency receiver, the VIM high frequency receiver and the VIM low frequency transmitter enable linking digital identities between the UIM and the VIM in the learning mode and for providing operative control of the valve in the active mode.

Abstract
The invention provides a radio frequency (RF) valve control system that replaces mechanical systems that physically links a button or a handle to a flush valve or hard wired electronic control systems that physically links a sensor/electronic switch to a valve actuator within a plumbing installation. The new system is characterized by two modules, a user interface module (UIM) for locating at or adjacent a plumbing fixture (such as a water closet or urinal), and a valve interface module (VIM) operatively connected to a flush valve actuator or a valve in the water supply line of the plumbing fixture. The UIM generally has the function of providing an RF valve control signal to the VIM and the VIM has the functions of receiving, analysing, and responding to the RF valve control signal and sending a signal to the valve actuator to initiate a flush cycle or initiating a valve control process to control a valve within the water supply line to start or stop water flow to the fixture. The system may be deployed as a single UIM/VIM pair or as multiple UIM/VIM pairs within a multi-fixture installation. In each case, each UIM/VIM pair communicates with its respective UIM or VIM in both a learning and active mode.

16. A plumbing fixture installation and valve control system comprising:
-
a user interface module (UIM) for installation adjacent a plumbing fixture, the UIM module having;
a UIM high frequency transmitter and a UIM low frequency receiver for communication in an active mode and a learning mode;
a UIM processor operatively connected to the UIM high frequency transmitter for instructing the UIM high frequency transmitter to transmit a high frequency master signal in the learning mode and a high frequency valve control signal in the active mode;
an activation system operatively connected to the UIM processor, the activation system responsive to a user input to cause the UIM high frequency transmitter to transmit the high frequency valve control signal in the active mode;
a valve interface module (VIM) for operative connection to a valve for controlling fluid flow through the valve and, in the learning mode, for communication with the UIM to link digital identities between the UIM and VIM and, in the active mode, to provide operative control of the valve, the VIM having;
a valve interface for operative connection to the valve;
a VIM high frequency receiver and a VIM low frequency transmitter for communication with the UIM;
a VIM processor for, in the learning mode, interpreting a high frequency master signal from the UIM and for responding to the high frequency master signal by activating the VIM low frequency transmitter to transmit a VIM digital identity and, in the active mode, for interpreting a high frequency valve control signal from the UIM and responding to the high frequency valve control signal to control fluid flow through the valve. - View Dependent Claims (17, 18)
