A method for the preparation of cyclopropyl carbinols by cyclopropanation of unsaturated alcoholates, utilizing a reagent system selected from magnesium metal and dibromomethane, and dibromomethane and a tertiary Grignard reagent, the reaction being carried out in the presence of an ether solvent. The integrated unique geometric folding pattern means provides enhanced folding accuracy and correct placement of interactive panels during collapse or assembly of the structure, and also greatly increases the flexibility for multiple unit combinations and component materials selection. Each conductive element is connected to a conductive pad member that has sufficient surface area in order to facilitate connection to a signaling device. The sensor is in communication with the microserver and operably connected to the component for monitoring parameters of the component. The rangedistance between the upright part of forklift tines and the palletized load combined with knowledge of the length of floor parallel tines of the forks will provide information to prevent any excessive penetration of the pallet hollow which excessive penetration can cause damage to either truck trailer walls, warehouse structures, or other palletized loads.
