Abstract: A system and method for testing whether proper connections (30, 34) are made between wire harnesses and fuel injector assemblies (26) includes at least one gripper mechanism (44) for grasping a selected portion (32, 36) of a wire harness associated with the fuel injector assembly (26). The gripper mechanism (44) preferably moves relative to the fuel injector assembly after it has been positioned on an appropriate support (40). The gripper mechanism (44) preferably grasps a selected portion (32, 36) of the wire harness and pulls it in a direction away from the fuel injector assembly (26). If a proper connection is made, the wire harness does not become disconnected from the fuel injector assembly. If a proper connection is not made, however, that is revealed as the gripper mechanism (44) pulls the wire harness off of the fuel injector assembly.

Abstract: A method for tracking the MOS oxide thickness by the native threshold voltage of a “native” MOS transistor without channel implantation for the purpose of compensating MOS capacitance variations is achieved. The invention makes use of the fact that in MOS devices the threshold voltage is proportionally correlated to the oxide thickness of said MOS device. Said threshold voltage can therefore be used to build a reference voltage Vx+Vth which accurately tracks the MOS capacitance variations in integrated circuits. Circuits are achieved to create a frequency reference and a capacitance reference using said method. Additionally a method is introduced to create a capacitance reference in integrated circuits using said MOSFET capacitors.
