The invention provides antibodies against Fibroblast Activation Protein and methods of using the same. The height requirement of stacked seed treatment systems can be lowered by elevated the discharge point of the treated seed without requiring additional expense transfer components. The customer can then use the transmitted CNC machining instructions to total profile machine their own part using their own CNC mill at the location where the part is likely needed. In addition, a program executing on the controller of the safety system performs a test to determine if each output module is operating normally. As a result, the degree of signal interference problem is greatly reduced.
