A sensor is configured to sense a parameter of an aqueous liquid. The sensor has an analog output port configured to provide an analog signal indicative of a sensed parameter, and a calibration memory device storing individual digital information indicative of a calibration of the sensor. A digital output port provides a digital signal indicative of the digital information. A treatment system and method is matched to the sensor.

Sensor with memory storing calibration information

A mobile device reads a test strip to determine a chemical condition of a liquid or a user inputs a treatment plan into the mobile device. The mobile device transmits the determined chemical condition or the input treatment plan to a liquid treatment system which treats the fluid in response to the determined chemical condition or the input treatment plan.

Spa/pool water treatment system and method

A mobile device reads a test strip to determine a chemical condition of a fluid. The mobile device transmits the determined chemical condition to a fluid treatment system which treats the fluid in response to the determined chemical condition.

Test strip mobile app system and method

Test strip

A motorized exercise apparatus for use with a power source comprising an exercise apparatus having a power supply configured to be connected to the power source. An electronically commutated motor is configured to drive the exercise apparatus. A controller is configured to connect a power supply to the motor to selectively energize the motor to drive the exercise apparatus and including an emergency stop feature. The controller selectively actuates the motor and disables activation of the motor when the emergency stop feature is actuated. An additional motor driven by the apparatus is configured to cause a dynamic braking action to slow the apparatus when the power source is disabled or when the emergency feature is actuated.
