A device includes a semiconductor chip including a frontside, a backside, and a side surface extending from the backside to the frontside. During operation, the computer system determines the performance metric for tasks performed by financial software during a time interval. Upon actuation of the actuator, the bolt deforms andor fails at the release zone and the attachment means moves farther out from the housing by a distance equal to the height of the release cavity. The tracker unit, in turn, is capable of updating the ground position, velocity and acceleration of the target to thereby track the target based upon the ground position, velocity and acceleration.
