Abstract
Standoff devices and methods of their use are disclosed. In various embodiments, a standoff device includes a spring-loaded core rod whose longitudinal movement causes lateral extension members to extend outward to provide the desired standoff action. The core rod is initially restrained in its motion by a restraining part made of or including a fusible material. Melting of the fusible material causes release of the spring-loaded core rod and, as a result, outward extension of the lateral extension members. Further embodiments are described.
