A power tool having a drive component and a housing. The device can also be configured such that the width of the active region is smaller than the width of the cladding layers of the stacked body; and a Ru-doped semi-insulating layer is provided in a space between the burying layer and the active region in both sides of the active region. The method also includes building at least one command request that includes the at least one network topology information request, and sending the at least one command request from the channel subsystem to at least one network entity. The bottom clamp preferably includes rear and forward members which may move along an arc-shaped interface to allow adjustment of the clamping contact position. An STI region is formed defining STI corners where a top surface of the silicon substrate and the STI region converge.
