Control utilizing non-contact switching for control and current sensing technology for operating a valve
First Claim
1. A control module comprising:
- one or more modules configured to provide a first control signal for controlling a first device in order to open or close a second device; and
also configured to respond to a change in a parameter sensed in relation to controlling the first device, and to provide a second control signal for controlling the first device based at least partly on the change in the parameter in relation to time.

Abstract
The present invention provides a control device featuring a control module featuring one or more modules configured to provide a first control signal for controlling a first device in order to open or close a second device; and also configured to respond to a change in a parameter sensed in relation to controlling the first device, and to provide a second control signal for controlling the first device based at least partly on the change in the parameter in relation to time. The first device may be a motor; the second device is a valve; and the parameter may be current. In operation, the first control signal is for turning on the motor in order to open or close the valve, and the second control signal is for turning off the motor in order to open or close the valve.

30. A method comprising:
-
providing a first control signal for controlling a first device in order to open or close a second device; responding to a change in a parameter sensed in relation to controlling the first device; and providing a second control signal for controlling the first device based at least partly on the change in the parameter in relation to time.

35. Apparatus comprising:
-
a valve configured with a motor and a conduit for allowing the passage of a substance based at least partly on whether the valve is either open or closed; and a control module having one or more modules configured to provide a first control signal for controlling the motor in order to open or close the valve; and
also configured to respond to a change in a parameter sensed in relation to controlling the motor, and to provide a second control signal for controlling the motor based at least partly on the change in the parameter in relation to time.
