A control module can include in at least one implementation an electronically actuated water control valve configured to shut off water flow through a water pipe, an electronic flow sensor configured to measure the flow of water through the water pipe, a temperature sensor configured to report water temperature, a water quality sensor, and a processing unit in communication with the electronically actuated water valve and the electronic flow sensor. The processing unit can be further configured to identify irregularities in the flow of the water through the water pipe, and in response to the identified irregularities, shut off the water flow through the water pipe.

Intelligent electronic water flow regulation system

To provide a tail lamp structure wherein a height in an upward and downward direction can be reduced to achieve miniaturization thereof. A tail lamp structure is equipped at a rear portion of a motorcycle. A board on which a stop lamp LED and a tail lamp LED are mounted in a spaced relationship from each other forwardly and backwardly is disposed in the forward and backward direction of the vehicle. The stop lamp LED and said tail lamp LED are isolated from each other by a reflector.

Tail lamp structure

PURPOSE:To improve the safety and reliability of the device by changing a stop deciding method corresponding to the condition of actually using an individual equipment. CONSTITUTION:The flow rate of the individual equipment to be used is previously stored in an individual flow rate storage equipment to be means 4. An individual equipment estimating means 2 estimates the individual equipment from the increase/decrease of the flow rate outputs an estimated individual arithmetic flow rate. When this estimated individual arithmetic flow rate is not contained in the individual flow rate stored in the individual flow rate storage means 4, an abnormal flow rate decision part 5 outputs an individual abnormal signal to an alarming means or stopping means 6. Corresponding to the time of the estimated individual arithmetic flow rate or the reset of an alarm, a normal individual flow rate registering means 7 stores this estimated individual flow rate in the individual flow rate storage means 4.
