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.

A control input for operating an actual vehicle actuator and a control input for operating a vehicle model are determined by an FB distribution law based on a difference between a reference state amount determined by a vehicle model and an actual state amount of an actual vehicle such that the state amount error is approximated to zero, and then an actuator device of the actual vehicle and the model vehicle are operated based on the control inputs. The FB distribution law determines a control input for operating the model such that a state amount error is approximated to zero while restraining a predetermined restriction object amount from deviating from a permissible range. A vehicle control device capable of enhancing robustness against disturbance factors or their changes while performing operation control of actuators that is as suited to behaviors of an actual vehicle as possible is provided.

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.

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 vehicle direction indicator system is designed to alert surrounding drivers of the intentions of the vehicle operator to continue in a forward direction. The indicator system has a plurality of indicator light end points and each end point is powered by the vehicle's electrical system and includes a housing, a light source holder and a lens attached to the front portion of the housing, and a vibration feedback element to indicate to the driver when the signal is activated. The end points may be positioned in various locations such as the grill, spoiler, side markers and the like and may simultaneously emit a color when the vehicle driver actuates the indicator system within the vehicle. The system is preferably mounted onto the front portion of the vehicle and is capable of signaling to other drivers at a four way intersection an intention to continue in a straight direction.

Malfunction or failure of mechanical, electrical and electro-mechanical equipment, for example equipment used in manufacturing operations, is often preceded by an increase in the operating temperature of at least some portion of the equipment. A temperature-sensitive, active material-containing actuator is pre-selected to operate at a pre-determined temperature indicative of impending equipment failure and placed in thermal contact with the equipment. If the equipment achieves the pre-selected temperature the actuator signals this by displaying a flag or providing some other passive visual indication. Alternatively, or additionally, the actuator may issue an electrically-powered alert including visual or audible alerts or a wireless communication. Selected actuators are based on smart materials including shape memory alloys (SMA), shape memory polymers (SMP) and paraffin wax, all of which may be adapted to operate over a temperature range sufficient to encompass the expected range of pre-determined temperatures.

The invention relates to an adjustable safety distance spacer for bicycles, comprising two guide tubes (1, 2), a spacer rod (5) which moves inside the aforementioned guide tubes and which passes through perforated plugs (9), a refracting rotor comprising four curved blades (7) and a circumferential protector (6) which is disposed at one of the ends of the spacer rod and which is solidly connected to said rod by means of a safety clevis (8), and two supports (3, 4) which are used to fix the guide tubes (1, 2) to the bicycle frame (10). In this way, the cyclist can adjust the size of a safety signal strip quickly, comfortably and safely using just one hand when he / she is being overtaken by another vehicle, thereby preventing the cyclist from being hit owing to the incompetency or carelessness of the driver of the overtaking vehicle.

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.
