A sling is held in a folded state under a cheek piece attached to the butt of a rifle or gun stock, and deployed by drawing from the cheek piece and attaching to a forward end of the rifle or gun. A rear sling end may remain attached to the rear of the rifle or gun at all times. The folded sling is stowed in a channel formed beneath the cheek piece by a releaseable flap, with a forward sling end exposed at the rear of the channel. The sling is deployed by drawing from the rear of the channel and then reaching forward to attach to the forward end of the rifle or gun. The sling may be returned to the folded state by folding the sling, releasing one side of the flap, placing the folded sling under the cheek piece, and reattaching the flap.

In one embodiment, a spark plug comprises: an electrically nonconductive body disposed in an electrically conductive shell; a side electrode extending from said shell; a sheath disposed within and protruding from a body first end of the electrically nonconductive body; a core disposed in the cavity; and a center electrode tip extending from the cavity through the opening. The sheath comprises a cavity extending from a sheath second end toward a sheath first end. The cavity connects to an opening disposed through the first end. The core is in electrical communication with the center electrode tip. The center electrode tip is in alignment with the side electrode.

To avoid searching for objects that are not effectively configured and therefore to mitigate connectivity and system failure, an intermediate routing object index (100, 103) is created to each and every object in a system (36). In a telecommunications system, for example, an object is only operational at a node (10, 30-34), such as a switch, upon receipt of all necessary configuration messages (102) from an overall system controller (12) responsible for overseeing operation of the node (10, 30-34) and the set-up of a connection. The routing object index stores (103, 108) an indication of the receipt of the necessary configuration messages and so provides a direct indication of whether the object exists and whether it is effectively configured. Consequently, during a connection establishment process in which control information, such as dialled digits (42, 150), indicates a called party (50) and more especially its serving node (34), the system of the present invention initially creates (100) and then subsequently accesses (156) the routing object index before attempting to locate the associated object (164). Should the routing object index fail to provide verification (106, 172) of a fully configured object or if the routing object does not exist (170), the routing object index causes the system to indicate (174) that a connection is not presently possible. The routing object index can also provide a mechanism for tracking (114-118) system configuration at a node level.

An auto darkening eye protection device comprising a shutter assembly adjustable between a clear state and a dark state and a control circuit. The control circuit is provided with a microcontroller, a delivery circuit, a sensing circuit and a weld detect circuit. The microcontroller is switchable between a sleep mode and a wake-up mode. The delivery circuit outputs a dark state drive signal to the shutter assembly to switch the shutter assembly from the clear state to the dark state upon enablement of the delivery circuit. The sensing circuit senses the occurrence of a welding arc and provides an output indicative of the occurrence of the welding arc. The weld detect circuit receives the output of the sensing circuit. The weld detect circuit enables a dark state drive signal to be delivered to the shutter assembly by the delivery circuit, and a signal to be delivered to the microcontroller to switch the microcontroller from the sleep mode to the wake-up mode whereby the shutter assembly is switched to the dark state without the aid of the microcontroller. The microcontroller can compensate for a startup of the microcontroller which was not caused by user power-up by bypassing at least one of a plurality of initialization and calibration routines for the auto darkening eye protection device. The microcontroller also includes a protective casing disposed generally thereabout to substantially prevent electromagnetic fields from interfering with the operation of the microcontroller.

A portable gun rack for transporting and supporting at least one firearm such as a shotgun or rifle. The portable gun rack has a butt support shelf with recesses to support the butt of the gun or guns being transported and a barrel support arm to support the barrels of guns being carried. A handle is located along the frame of the gun rack. A pair of legs are automatically pivoted outwardly as the gun rack is rested on the ground. In this way, guns not being used can be safely and cleanly supported on the portable gun rack.

A sling is held in a folded state under a cheek piece attached to the butt of a rifle or gun stock, and deployed by drawing from the cheek piece and attaching to a forward end of the rifle or gun. A rear sling end may remain attached to the rear of the rifle or gun at all times. The folded sling is stowed in a channel formed beneath the cheek piece by a releaseable flap, with a forward sling end exposed at the rear of the channel. The sling is deployed by drawing from the rear of the channel and then reaching forward to attach to the forward end of the rifle or gun. The sling may be returned to the folded state by folding the sling, releasing one side of the flap, placing the folded sling under the cheek piece, and reattaching the flap.
