A goal to ground indicator device indicates a ready and / or upset condition of a ground supported goal such as a soccer goal that has at least one bar that lies in contact with the ground. An indicator arm is movable relative to the contact arm between a ready position and an upset position. A contact arm cooperates with the indicator arm. A biasing element biases the indicator arm to the upset position. When the bar of the goal is no longer in contact with the ground the indicator arm moves from the ready position to the upset position.

An indicator device for alerting the driver of a pickup truck to the orientation of the tailgate includes a housing assembly and an indicator assembly carried by and extending from the housing assembly. The housing assembly is attached to the tailgate of the pickup truck in a position that causes at least a portion of the indicator assembly to extend from the side of the truck so that the driver can see the extending portion in the side view mirror of the truck. Viewing the position of the indicator assembly allows the driver of the truck to ascertain the position of the tailgate.

Apparatus for allowing ventilation as usual for underground tunnels through a ventilation shaft opening to atmosphere yet preventing underground flooding from surface waters pouring through the grate, comprises an assembly that fits within the ventilation shaft and includes one or more panels held in an upright home position that allows ventilation as usual but is releasable to rotationally gravitate to a lower sealing position closing a passage between the ventilation shaft and atmosphere to prevent water from entering the underground tunnels. A panel position indicator moves from a hidden position to a visible position with lowering of the panels to visually signify that the panels are lowered and that flooding protection is activated.

An indicator arm is movable relative to the contact arm between a ready position and an upset position. A contact arm cooperates with. A biasing element biases the indicator arm to the upset position. When the bar of the goal is no longer in contact with the ground the indicator arm moves from the ready position to the upset position.

Described herein is a system for a mobile platform includes a storage compartment that defines an interior space. The storage compartment forms part of the mobile platform. Further, the storage compartment is operable to physically separate the interior space from an exterior space. The system also includes a visual indicator that provides to the exterior space a visual indication of a storage capacity status of the interior space of the storage compartment.

The present invention is a traffic control apparatus to further control a flow of traffic. The traffic control apparatus comprises a base structure which supports a figurine, wherein the figurine is operational to help solicit attention from the flow of traffic. The traffic control apparatus further comprises a method for creating a perceptible safety warning using a combination of the base structure and the figurine.

A goal to ground indicator device indicates a ready and / or upset condition of a ground supported goal such as a soccer goal that has at least one bar that lies in contact with the ground. The indicator device includes a base plate, a contact arm mounted to the base plate and movable relative to the base plate and an indicator arm mounted to the base plate for cooperation with the contact arm. The contact arm and a portion of the base plate are configured for contact with the bar. The indicator arm is movable relative to the contact arm between a ready position and an upset position. The indicator arm is positioned such that a portion of the contact arm cooperates with a portion of the indicator arm to temporarily maintain the indicator arm in the ready position. A biasing element biases the indicator arm to the upset position. The contact arm resting in the base plate cooperates with the indicator arm against the biasing element to maintain the indicator arm in the ready position when the bar overlies the contact arm. When the bar is moved from the contact arm, the biasing element exerts a force to move the indicator arm from the ready position to move the contact arm from the base plate to disengage the indicator arm and to continue moving the indicator arm to the upset position. The contact arm can be mounted directly to the bar.

A marker for the wingtip or other extremity of an aircraft. The marker includes a fabric pouch having a flap containing hook and loop fasteners, to hold the pouch on the aircraft extremity. A fabric tube extends outwardly and substantially horizontally from the pouch and supports a marker flag at its tip. The fabric tube contains a breakable support rod, so that if the aircraft wingtip collides with an object, the support rod will break and the flag will droop, providing a visible indication that a collision has occurred. The broken rod can then be replaced.
