Abstract: An electric power take-off system for mounting to a truck body to complement an existing power-take-off system powered by an internal combustion engine. The system includes a motor, battery, fluid reservoir, pump and a digital sensing unit for sensing at least one of fluid pressure or a fluid flow rate within the fluid delivery conduit. The digital sensing unit also includes an output capability. The system also includes a motor controller in operable communication with the digital sensing unit as well as the motor for instantaneously controlling the rotational speed of the motor. The motor controller in turn limits operation of the motor only to occasions of truck function operation initiated by the system operator.

Abstract: One aspect of the invention provides a sheath including: a cylinder defining a central passage; a balloon located along an external surface of a distal end of the cylinder, the balloon lying substantially flush with or recessed from the external surface when deflated, but capable of projecting beyond the external surface when inflated; and an inflation port located at a proximal end of the cylinder, the inflation port in fluid communication with the balloon. Another aspect of the invention provides a kit including: a sheath as described herein and instructions for use.
