An electrical plug assembly may include a body having a plurality of electrical contact blades and an actuator. In particular embodiments, the plug assembly includes a shield member having a back and a front. The back has an opening arranged to receive the body therein and the front has a plurality of openings, wherein each opening is shaped, sized, and aligned with a respective one of the plurality of contact blades of the body. In a particular embodiment, the plug assembly further includes a biasing member positioned between the body of the plug and the back side of the shield member to operatively interact with the shield member to prevent electrical current flow and during operation the shield member may slide over the body and operatively engage the actuator to allow electrical current flow.

The present invention is a system and method for precise absolute time event generation and capture. One embodiment of the present invention is a programmable hardware module for TTL pulse generation and capture in absolute time. The nominal accuracy of the programmable hardware module is 25 ns. The time reference is an on-board GPS (Global Positioning System) receiver. The hardware embodiment of the present invention can generate eight independently programmable outputs and capture the times on eight independently programmable inputs. An exemplary application for the present invention is triggering external light sources, and flash-lamp pumped lasers in particular, at specific times for calibration of cosmic-ray observatories. A software embodiment of the present invention is implemented in a Linux software device driver interface featuring an extensive set of user commands.
