Abstract: A system, apparatus and method are provided for testing a secondary servo control circuit in a redundant control configuration. A first circuit is configured to receive a control signal and to control an attribute of an actuator based on the control signal using a first control input of the actuator. A second circuit is configured to test operation of an actuator circuit using a test signal. The actuator circuit includes at least part of the second circuit and a second control input of the actuator. The test signal is selected to avoid causing independent motion of the actuator. The actuator could be a dual coil servo valve, and the test signal could be a current (such as a DC current, an AC current, or a pulsed current) having a magnitude less than a bias current of the actuator.

Abstract: Stacking of electronics modules, boards or cards, hereinafter referred to as cards is described. Each card in a stack is connected logically to a host via a single physical bus slot, and can detect its relative position in the stack on initial power on and make use of that information to grab an appropriate resource pool. In one embodiment, a top most card is used as a reference and the rest of the cards in the stack derive a relative address with respect to the top most card. A few lines are dedicated between neighboring cards through which the cards can share their relative address information with succeeding cards and automate resource allocation based on the address information.
