摘要： A vehicular lamp includes a lamp outer case formed by a cover and a lamp housing; a light source disposed inside the lamp outer case; and a light guide that guides light emitted from the light source, wherein the light guide is shaped as a column. The light guide includes a first extension portion that extends on a horizontal plane side, and a second extension portion that extends on a vertical plane side with respect to a reference line that extends in a direction inclined 45 degrees with respect to the horizontal plane. An outer surface of the light guide includes an incident surface to which light emitted from the light source is incident, an internal reflection surface that internally reflects light incident from the incident surface, and a radiation surface that is formed as an outward-convexly curved surface and radiates at least light reflected by the internal reflection surface. ρ1 is a curvature of the radiation surface in a cross section perpendicular to a direction in which the first extension portion extends, ρ2 is a curvature of the radiation surface in a cross section perpendicular to a direction in which the second extension portion extends, and ρ1 is smaller than ρ2.

摘要： A security gateway connects an external portion of a virtual private network to an internal secured portion of the network. The gateway is arranged to identify automatically when a communication session exists between two mobile workstations both of which are connected in the external portion of the network. The mobile workstations are then enabled to communicate with each other without using the gateway as an intermediary. This communication can be secured. The route by which packets are transferred between the workstations may then be optimised.
