A modular transfer system for workpieces. While a programming voltage Vpgm is applied to a selected wordline WL<i>, a cutoff voltage Vss is applied to a nearby unselected wordline closer to the ground selection transistor GST to isolate a first local channel Ch1 from a second local channel Ch2. This causes the vehicle to send a wireless warning signal to a call center which already has emergency contact numbers on file. The camera is connected to a laptop or stationary computer via a USB cable. In certain embodiments, fail-safe circuitry is also provided that includes a relay receiving controller signals.
