Abstract
A low-cost safety valve for gas lines and similar supply lines that can be remotely activated via a secure wireless link employing a low leakage sealing mechanism that is compatible with low energy actuators to for extended battery life. A miniaturized controller and wireless electronics assembly provides the control mechanism for actuating the valve, as well as reporting data regarding the valve status to wireless interrogators or external networks via an ad hoc wireless network. A variety of simple magnetic valve operating mechanisms can be implemented with the miniaturized electronic control circuits and the valve body. Such control actuation mechanisms enable automatic resetting or manual resetting valves. The gas line shut off valve can provide important safety benefits at an affordable price.
