Cervis received a call late on Tuesday the week before the World of Concrete trade show for Sidewalk Grading Systems.  Sidewalk Grading Systems manufactures an attachment to backhoes used to simplify the grading of earth along sidewalks during construction.  The problem was that the attachment is often detached from the machine and running wiring from the in CAB switches and joystick were commonly compromised by being in the open environment.  The problem was solved quickly by using Cervis’ SmaRT wireless base units.  One wireless device was mounted in the CAB of the machine and monitored switch inputs to be transmitted wirelessly to the other wireless base unit mounted on the attachment.  The attachment base unit received power from batteries and provided outputs pursuant to the switch inputs in the CAN to drive the attachment valves coils.  “We were able to listen to the customers requirements and problems and apply our flexible SmaRT wireless base units as wireless contact monitors to drive valves on the attachment.  The most impressive thing to the customer was our simple, quick response to get him a solution in only three days for delivery to the World of Concrete trade show so he could improve the exhibition of his machine. ” says Kevin Hadley of Cervis.  With such a successful initial installation the customer has already begun discussion of increasing the requirements to include transmission of sensor inputs to continue the wireless concept that has pushed this machine to the forfront of wireless machine technology.
