Embodiments of the invention provide a method of creating, based on an operating-system-scheduled thread running on an operating-system-visible sequencer and using an instruction set extension, a persistent user-level thread to run on an operating-system-sequestered sequencer independently of context switch activities on the operating-system-scheduled thread. The semiconductor device, among other elements, may include a gate structure located over a substrate, the gate structure including a gate dielectric layer and gate electrode layer. Importantly, the system allows the electrical equipment to be reconfigured without redrilling of a concrete sub-floor which is used as an anchor point for the restraint system attached to the electrical equipment. A biasing member couples the cleaning member to the rake handle, permitting movement between retracted and extended positions.
