Abstract: In an example embodiment, an apparatus comprising a physical layer processing device that comprises logic configured to process a packet received from a physical layer interface is disclosed. The physical layer processing device logic is further configured to determine a preamble portion of the packet and a data portion of the packet. The physical layer processing device logic is further configured to insert a timestamp into the preamble portion of the packet. The physical layer processing device logic forwards the packet with the timestamp inserted into the preamble.

Abstract: A circuit is presented for coupling a storage capacitor to a capacitor shorting switch whereby voltage across the shorting switch is maintained at a reduced potential relative to the storage capacitor so that the voltage and potential current at the switch contacts is maintained at levels wherein it is impossible for the release of sufficient energy into the surrounding atmosphere to cause ignition of a flammable mixture of gas and air. This is accomplished by coupling the storage capacitor to the switching device via a variable voltage divider network controlled by an SCR with a zener diode controlled gate circuit and a varistor.
