Abstract: A microelectromechanical system (MEMS) mirror device includes a frame that defines a frame cavity; a suspension assembly; and a mirror body coupled to the frame by the suspension assembly such that the mirror body is suspended over the frame cavity. The mirror body comprises a sandwich structure that includes a front plate, a back plate, and a hollow core assembly arranged between the front plate and the back plate. The front plate and the back plate define a thickness dimension of the mirror body. The hollow core assembly includes a plurality of support structures that extend between the front plate and the back plate and define a plurality of cavities between the front plate and the back plate.

Abstract: A guardrail mounting arrangement comprises a support post having a face surface including a plurality of receiving slots formed therein. The receiving slots are aligned in a pair of spaced columns. At least one mounting bracket has a pair of side walls, each including a series of depending ears. Each of the ears are sized to be received in one of the receiving slots formed on the support post. The pair of side walls define an open interior. A guardrail section extends between a first end and a second end. The first end of the guardrail section is sized to receive within the mounting bracket such that the mounting bracket supports the first end of the guardrail section along the support post.
