The described principles provide a method and system for identifying potentially closed roads and potentially open roads based on reroute requests, and of accommodating the potential road closure. If a reroute request is received from a user on a given route, the avoided roads of the route may be deemed potentially closed.

A valve has a body with two ports and a valve element for controlling fluid flow between those fluid ports. A solenoid actuator includes a moveable armature operatively coupled to the valve element and defining first and second chambers on opposite sides of the armature. A bore extends through the armature between those chambers. A damping piston, slideably located in the bore, has a damping orifice forming a continuously open path there through. A spring biases the damping piston into a normal position in a steady state of the valve and allows bidirectional armature motion therefrom. When the armature moves at low velocity, a pressure increase in one chamber is relieved by flow through the damping orifice. As the armature velocity increases, so too does pressure in the one chamber, causing the damping piston to move relative to the armature, thereby adding damping force from the spring to the armature.

A transmitter unit is described for an open path gas detector. The unit comprises: an enclosure (14) having a window (16); and a coherent radiation transmitter (10) , e.g. a tuneable laser diode transmitter, located within the enclosure and configured to direct a beam of radiation through the window. Th window is slanted with respect to the axis of the beam emitted by the transmitter such that no radiation from the transmitter that is directly incident on the window is reflected by the window directly onto the transmitter. Thereby interference fringes within the emitted radiation are reduced. Alternatively, the window may be replaced by a lens followed by an aperture such that the beam emitted by the transmitter is focused onto the aperture, thereby forming a beam of radiation passing out of the enclosure.
