Abstract
The invention relates to bimetallic leaf spring devices (100) that are responsive to changes in temperature, and methods of constructing and utilizing such devices. In one embodiment, the invention includes a clamping apparatus including a first strip (110) of a first material and a second strip (120) of a second material. The second strip (120) may be attached to the first strip (110) at least two attachment locations. The second strip (120) may be spaced apart from the first strip (110) at least one section between the at least two attachment locations, and at least one of the first material and the second material may include a thermally expansive material.
