Abstract: A global positioning system (GPS) controlled marking apparatus for staking and a method of using the apparatus to stake a surface. The apparatus uses a standard architectural or other surface site application program and a stakeout driver program in a standard computer and includes a GPS receiver, a stakeout tool, an autopilot, a vehicle, a geographical drawing converter, and a location comparator. The geographical drawing converter converts an image of a drawing pattern to geographical mark locations. The autopilot guides the vehicle to the geographical mark locations. The location comparator detects a location march between the geographical mark locations of the drawing pattern and a current geographical location determined by the GPS receiver. Information for the location match is used by the stakeout tool for driving a stake into the ground.

Abstract: Method and system for applying an adhesive agent to a covering material in the process of bonding the covering material to a foam cushion member to produce a bonded unit forming a seat. As a base material of the adhesive agent, only a primary component material and secondary curing agent are used, without any organic solvent added in the primary component material. Heat of a predetermined temperature is continuously applied to the primary component material by heating elements so as to retain its lowered viscosity through a whole fluid passage from a storage point to a spray gun, so that the heated primary component material in a fluid state may be injected from the spray gun, while being mixed with the curing agent in the air at the same time, thereby applying a properly atomized state of the mixture, as an adhesive agent, to the covering material.
