Abstract: Systems and methods for leak detection and remote, non-intrusive, automatic shutoff in residential regulators are provided. Such systems and methods can include a shutoff device that includes a mounting bracket for mounting on a supply container, a linking device for coupling to a knob of a valve of a regulator of the supply container, and an actuator for, responsive to a control signal, automatically rotating the linking device, which rotates the knob, which rotates the valve from an on position to an off position. In some embodiments, a leak sensor can detect a presence of a fuel leak and, responsive thereto, transmit the control signal to the actuator, and in some embodiments, a position sensor can determine that a current position of the valve is indicative of the on position and, responsive thereto, transmit the control signal to the actuator.

Abstract: In general, the disclosure is directed to sealed enclosures and devices that include enclosures for protecting enclosed heat sensitive components from the heat generated by enclosed heat producing components. Heat producing components within the enclosure may be placed to achieve uniform distribution of heat produced by the heat producing components, to optimize the dissipation of heat from the heat producing components to the enclosure, and to minimize the heat experienced by the heat sensitive components. The exterior of the enclosure may be designed to increase thermal dissipation and to protect against thermal radiation.
