Abstract: The application provides a system comprising a water blocking device, a support structure, an injection machine, a resin impregnated lining hose and a light curing machine. The water blocking device blocks water and creates space for repairing. The support structure jacks up the deformation of pipelines. The injection machine injects polymer into the gap between the support structure and the HDPE pipes and the defective soil. A resin impregnated lining hose is inflated to attach to the support structure before being cured by UV lights. A CIPP (Cured-in-place pipe) liner is formed. The application carries out the trenchless rehabilitation of deformation of HDPE pipelines by integrating the method of the lining steel ring supporting, polymer injection and CIPP process. The defective soils are stabilized and further defects after repairing is avoided. The application is advantageous to the trenchless rehabilitation for double wall corrugated pipeline (diameter over 800 mm).

Abstract: Use of measurement system and detection module with a burr instrument for surgical procedures. The measurement system may include sensors (e.g., displacement, acceleration, and/or force sensors) that may be utilized to detect potentially hazardous operation of the burr instrument. For example, when penetrating through the cortex of the bone the measurement system may be operated in a unicortical mode such that when the burr passes through the cortex of the bone, the instrument operating may be arrested to avoid damage to surrounding tissue. Moreover, the system may be utilized to detect a slip or sudden loss of contact of the burr instrument such that the instrument may be arrested to avoid damage to surrounding tissue. Furthermore, the burr instrument may have a predetermined ramp-up speed.
