State of the art processor systems, esp. The work area is configured to receive a joined structure including a substrate and a die. The internal combustion engine is operated, at least some of the time, at an equivalence ratio less than 1 and a boost pressure ratio greater than 1. The latch circuit further includes an activation circuit connected to the set and reset terminals of the flip-flop and to the common source terminal in order to dynamically short-circuit the set and reset resistances during the falling edges of the signal applied to the switch. The enclosure has a bottom wall and at least one sidewall disposed around a perimeter of the bottom wall, the at least one sidewall configured to urge the tangs of the metal shield inward when the metal shield is disposed in the enclosure.
