Abstract: A system allowing the wireless transfer of data between a first device having a microcontroller and a second device when the first and second devices are positioned adjacent each other is described. The system includes a reader circuit and tag circuit. The reader circuit is operatively connected to the first device and provides oscillation energy to the tag circuit when the tag circuit is coupled to the reader circuit. The reader circuit receives coded information from the tag circuit and delivers the coded information to the microcontroller. The tag circuit includes a coil and logic enabling patterned oscillation at least two discrete frequencies such that the patterned oscillation is representative of coded information within the tag circuit. The system may be configured to a variety of product pairs, including consumer product pairs, to control the operation of the product pair or collect information about the operation of the product pair.

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.
