The pneumatic motor comprises an output shaft, the transmission assembly comprises a driving bevel gear arranged on the output shaft, a transmission bevel gear engaged with the driving bevel gear, a driven rod being arranged on the transmission bevel gear, a pushing block being eccentrically arranged on the driven rod, a transmission rod assembled with the saw, and a thermal insulator sleeved on the transmission rod without being shifting along with the transmission rod. The transmission rod comprises a groove for placing the pushing block to slide therein, when the transmission rod is driven to reciprocate in a linear track, a tail end of the transmission rod not connected with the saw being limited by the thermal insulator to only move in the linear track.

Abstract: The invention relates to lithium ion battery, more particularly to a lithium nickel cobalt manganese oxide (Li(Ni0.8Co0.1Mn0.1)O2) composite material, including lithium nickel cobalt manganese oxide and a hydrophobic material coated on the surface of lithium nickel cobalt manganese oxide. The hydrophobic material coated on the surface of lithium nickel cobalt manganese oxide is insoluble in water, so that the lithium nickel cobalt manganese oxide composite material solves the problem that the batteries using conventional lithium nickel cobalt manganese oxide materials easily absorb water. A method for preparing the lithium nickel cobalt manganese oxide composite material is also disclosed.

Abstract: Described herein are a system and method of training a motor vehicle operator in crash-avoidance skills. Critical crash-avoidance skills comprise actively scanning a driving environment to identify, recognize, and remember what is seen; adjusting vehicle speed and position to accommodate road conditions, visibility, and traffic; proactively identifying and responding to potential hazards before the potential hazards become immediate hazards; recognizing, assessing, and responding to driving risks; creating a space cushion in order to identify and maintain possible escape routes; and identifying and minimizing visual, manual, and cognitive distractions. Training comprises at least one interactive driving simulation in which use of technology by a motor vehicle operator impacts performance of the motor vehicle operator.
