A Micro Electrical Mechanical System oscillator supplies a MEMS clock signal to a digital locked loop that generates an output clock signal having a frequency that corresponds to a desired frequency ratio between the MEMS oscillator output signal and the digital locked loop output signal. The IND sesame holds its seed in capsules for four or more weeks after ideal harvesting time, during extended adverse weather conditions, thus offering the grower flexibility as to when to harvest. The connector slide block is preferably lockable in the connector on the displacement from the in-use position to the safety position. A system for surface treating the cable trays renders the trays electrically non-conductive at desired portions of each cable tray, while leaving exposed certain portions of each tray.
