Patent ID: 7239064

Claim:
A micro-electromechanical temperature sensor device, comprising: a thermal bimorph comprising a first mechanical latch and a first electrical contact; and a pawl comprising a second mechanical latch, the second mechanical latch disposed at a latching distance from the first mechanical latch, the latching distance corresponding to a latching threshold temperature; and a second electrical contact disposed at an electrical contact distance from the first electrical contact, the electrical contact distance corresponding to an electrical contact threshold temperature; wherein the first mechanical latch moves toward the second mechanical latch and the first electrical contact moves toward the second electrical contact when the thermal bimorph experiences a temperature change in the direction of the latching threshold temperature; and wherein the first mechanical latch engages with the second mechanical latch when the temperature reaches the latching threshold temperature; and wherein the first electrical contact contacts with the second electrical contact when the temperature reaches the electrical contact threshold temperature.
