A wafer transfer system having a temperature control apparatus. The retention member is provided with a slope surface that transforms into a force acts in a direction from a site relatively near to a base end of the retention member to the distal end of the retention member. At least one connector is provided for removably connecting each shelf to a portion of the frame. The steering device is configured to controllably redirect the flow of water so as to control an amount of lateral force generated by the paravane. The pressure sensors provide pressure data to a processor that analyzes the data to determine if the tissue-contacting area of the distal segment is contacting the tissue. The present invention also describes the method of manufacture and method of use for such laminated composite radius filler.
