Abstract
A temperature actuated safety device for sensing increased temperatures in the vicinity of an electrical outlet and providing an alert of the condition is provided herein. Here, a safety device can be coupled to an outlet and can include an alarm support member; an alarm coupled to the alarm support member; a switch coupled to the alarm support member, the switch being electrically connected to a power source and to the alarm; and a shape memory alloy member that is immovably coupled to the alarm support member and is also coupled to the switch. The shape memory alloy is configured to actuate the switch to provide power to the alarm when the shape memory alloy reaches a transformation temperature that is indicative of a dangerous temperature condition in or around the electrical outlet.
Claims20
An apparatus comprising:
- an electrical outlet;
- an alarm support member coupled to the electrical outlet;
- an alarm coupled to the alarm support member;
- a switch coupled to the alarm support member, the switch being electrically connected to a power source and the switch being further electrically connected to the alarm;
- and
- a shape memory alloy member, the shape memory alloy member having two ends, where the first end is immovably coupled to the alarm support member and the second end is coupled to the switch;
- wherein the shape memory alloy is configured to actuate the switch to provide power to the alarm when the shape memory alloy reaches a transformation temperature.
A heat-actuated alarm for use with an electrical outlet comprising:
- an alarm support member;
- an alarm coupled to the alarm support member;
- a switch coupled to the alarm support member, the switch being electrically connected to a power source and the switch being further electrically connected to the alarm;
- and
- a shape memory alloy member, the shape memory alloy member having two ends, where the first end is immovably coupled to the alarm support member and the second end is coupled to the switch;
- wherein the shape memory alloy is configured to actuate the switch to provide power to the alarm when the shape memory alloy reaches a transformation temperature.
