Abstract: A method of managing transient thermal stresses in a wall of a fluid-carrying or fluid-containing structure, the structure having a temperature ramp rate limit associated with its structure walls. The structure is provided with flow passages in the structure walls, and the temperature of the structure walls is monitored. If a rate of change of temperature of the structure walls becomes too high, fluid is circulated through the flow passages to heat or cool the structure wall during hot or cold transient thermal events, respectively.

Abstract: An accessory support apparatus for a hand held electronic device to provide hands free use and stability thereof includes a connector bar and a support member that are attachable by integrally formed coupling members. In a first preferred embodiment the support member is in the form of a support stand that is attachable to the connector bar and includes a leg and a bracket portion and a hinge portion located therebetween to provide for relative movement of the leg with respect to the bracket portion. In a second preferred embodiment, the support member is in the form of a bracket bar that is attachable to a desired surface so that when the connector bar is coupled thereto, the hand held electronic device is maintained in a fixed position on the wall.
