Benefits of technology

This patented technology allows for efficient utilization of power during operation by connecting an accumulation device (such as a spring or rubber tube) with different components such as a steering wheel control valves, a gearbox controllers, a work-pilot's handgrip, various parts like springs, bearings, etc., and other related equipment together into one unit called a machine tool. These connections allow fluid communication between these devices while also allowing them to absorb excessive force without losing too much power. Overall this design improving efficiency saves money compared to traditional methods used at home.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving efficiency during use of power from an electric or hybrid vehicle's battery-power supply. Specifically, current systems have low performance due to their slow response times caused by changing direction frequently between different modes (brakes). Additionally, these systems require frequent maintenance because they constantly adjust the position of shift lever based upon how hard it needs to move forward/backward.
