Abstract: A magnetic excavation marker is described below that includes a magnet and a stiff, resilient and brightly colored visual indicator. The marker is used by placing the marker onto an object to be protected, such as a manhole cover or valve. The magnet attaches the marker to the protected object with magnetic force. The marker will then protect the object by providing a highly visible indication of the presence of the object, even if the object is buried. The stiff and resilient qualities of the visual indicator ensure that it will remain upright and visible, even after it has been stepped on or run over. A handle is attached to the magnet or to a housing holding the magnet. The handle gives a user added leverage to aid in overcoming the force of the magnet when the user desires to remove the maker from the protected object.

Abstract: A method of protecting a networked industrial controller from network storms is disclosed in the specification. The networked industrial controller has a real-time operating system and communication components performing communication exchanges with connected networks. The method comprises steps of: (a) Initializing a watchdog thread monitor thread to have a high priority within the real-time operating system's kernel level; (b) configuring a watchdog thread to periodically (every TAlive time) send an alive event signal to the watchdog thread monitor thread if all other threads of application programs are operating normally; (c) starting the watchdog thread monitor thread waiting for receiving the alive event signal within a timeout period TAliveTout (TAliveTout is longer than TAlive); (d) identifying a network storm in response to the alive event signal; and (e) controlling the communication exchanges in response to the alive event signal and current phase of the watchdog thread monitor thread.
