Methods and systems for running multiple operating systems in a single embedded or mobile device are disclosed. The first section on the first surface of the prism has a length that is at least four times as long as its width. Switching circuitry also within the short-circuited IC selectively isolates the short-circuited IC from the other ICs on the wafer in response to the control circuitry sensing the short circuit. In other aspects, the electrical component is a battery charger and the electrical circuit is a charging circuit.
