A frame transmitting apparatus transmits a frame to a frame receiving apparatus. The first conductive layer includes at least one powerground plane. The arm has an opposite, distal end having a support element for supporting work tools associated therewith. A selected amount of repair material is cold sprayed into the notched opening, including into the at least one notch. The resinous part includes at least two different multifunctional epoxy resins with different functionality selected from difunctional, trifunctional, and tetrafunctional epoxy resins, certain toughening components, and inorganic filler particles as a rheologythixotrophy modifying component. The initiation of laser-induced damage is reduced by conditioning the optic at low fluences below levels that normally lead to catastrophic growth of damage.
