to the housing bottom surface and are configured to support several energy conversion elements 300 fig1 clearly show the alignment of the actuator assembly the resilient section 110 and the actuator bar 111 it has to be understood any force applied on the resilient section 110 is transmitted to the actuator bar 111 the actuator bar 111 is coupled to a vertical arm 302 by means of a bar attachment part 301 as shown in fig1 further the actuator bar 111 comprises a resilient member 1000 connected to inner frame 202 the resilient member 1000 as shown in fig1 through fig1 comprises an extended member 1002 mechanically coupled to the actuator bar 111 the extended member 1002 pass through the inner frame 202 in such way that the inner frame only permits the vertical movement of the extended member 1002 a spring 1001 and a buffer 1003 are fixed to the housing by means of support 202 the resilient member 1000 provides a reciprocal motion of the bar 111 therefore after a vehicle or pedestrian interaction the actuator bar 111 returns to its original position a single unit for energy conversion as show in fig2 comprises first actuator or movable bar 303 said.
