A dual power automatic transfer switch mechanism comprises a switch housing; a first spring; a second spring; a first pin which is disposed to correspond to a first power supply, the first spring acts between the first pin and the switch housing; and a second pin which is disposed to correspond to a second power supply, the second spring acts between the second pin and the switch housing. The dual power automatic transfer switch mechanism further comprises a first driving disk is configured to actuate the first pin moves between a first power-on position and a first power-off position; and a second driving disk is configured to actuate the second pin moves between a second power-on position and a second power-off position. The first and second driving disk are configured to rotate synchronously such that the first and the second pin cannot be in the power-on position at the same time.

A delay-locked loop (DLL) to produce a plurality of delayed clock signals comprising combinational logic for false lock detection is provided. The combinational logic uses only a subset of the plurality of delayed clock signals to provide a forward indicator indicating a delay period (&#x394;t) is longer than a desired delay period. The combinational logic further provides a back indicator indicating the delay period (&#x394;t) is shorter than a desired delay period.
