A vehicle safety system is for preventing child abandonment in a vehicle. The vehicle safety system may include a controller coupled to a flow sensor, a temperature sensor, and a seat sensor. The controller may be configured to detect when the vehicle is in a fueling state based upon the flow sensor, detect occupancy of a child safety seat based upon the seat sensor, and detect when a driver side door is in an open state based upon a driver side door sensor in the vehicle. The controller may be configured to when the driver side door has entered the open state, when the child safety seat is occupied, and when the vehicle does not enter the fueling state within a time period, then cause the vehicle to enter an alert state.

A fuel tank for a vehicle includes a main tank comprising a first tank volume defined by an outside wall and an auxiliary tank extending from an aperture provided in the outside wall. The auxiliary tank is formed as a pocket-shaped continuation of the outside wall into the first tank volume bounded by the outside wall. The auxiliary tank forms a second tank volume which is separated from the first tank volume and opens into a filler neck which runs inside the first tank volume and emerges on the outside wall of the main tank.

A storage tank having a wire or wire winding embedded in the wall of the storage tank is disclosed. The wire may be positioned such that it is compromised if the storage tank is deformed to a certain degree. The wire, for example, may form a helical shape proximate to the outer surface of the wall of the storage tank.

An atmospheric box for use with a fuel vent pressure sensor is operatively connected to a fuel tank of a vehicle. The atmospheric box includes a base including a floor, a sidewall extending upward from the floor and having an outer perimeter, and a drain hole opening in the floor, and a cover including a top section, an outer wall extending downward from the top section and having an inner perimeter substantially similar to the outer perimeter of the sidewall, thereby creating an interference fit between the cover and the base. An inner labyrinth wall extends downward from the top section inward of the sidewall, and a tube joint in the cover defines an opening inward of the inner labyrinth wall. The atmospheric box provides access to the atmosphere for measuring pressure while blocking water and debris intrusion.

Methods and systems are presented for diagnosing operation of a fuel tank pressure sensor. The methods and systems may include releasing fuel vapors from a fuel tank to an engine when an engine is rotating in a fuel cut out mode while a catalyst temperature is greater than a threshold temperature to determine whether or not the fuel tank pressure sensor is degraded.

A pressure sensor receptacle for the fastening of a pressure sensor to a motor vehicle tank, and a tank device that includes a pressure sensor receptacle. The pressure sensor receptacle includes a receptacle body having a substantially cylindrical shape with a first axial end forming a fastening portion of the receptacle body, the fastening portion configured for being plugged through an opening of the motor vehicle tank until a first bearing surface of the receptacle body bears against an edge of the opening, wherein the first bearing surface is configured to bound the fastening portion; and a locking body having a second bearing surface, the locking body configured for mounting and locking onto the fastening portion such that the second bearing surface bears against an opposite side of the edge of the opening to thereby clamp the pressure sensor receptacle to the edge of the opening by the receptacle body at one side and by the locking body at another side.

Methods, systems, and apparatus for monitoring a cylinder. The system includes a plurality of sensors connected to the cylinder and configured to detect deformation data associated with the cylinder. The system includes a controller communicatively coupled to the plurality of sensors. The controller is configured to determine a damage value based on the detected deformation data when the cylinder endures impact damage. The controller is configured to communicate a notification when the damage value exceeds an impact damage threshold. The system includes a filling controller communicatively coupled to the plurality of sensors. The filling controller is configured to control a valve for filling the cylinder with a fluid. The filling controller is configured to detect damage to the cylinder above a specified threshold as the cylinder is filled with the fluid. The filling controller is configured to automatically perform a safety action when the damage to the cylinder is detected.

A vehicle comprising an interior; a heat source in thermal communication with the interior; a source of ultraviolet light disposed to emit the ultraviolet light into the interior; and a controller in communication with the heat source and the source of the ultraviolet light, the controller configured to cause (i) the heat source to increase a temperature of the interior, (ii) the source of the ultraviolet light to emit the ultraviolet light into the interior, or (iii) both (i) and (ii) upon receiving a command from a remote user interface. The vehicle can further include a combustion engine that combusts fuel to propel the vehicle. The vehicle can further include a battery in electrical communication with the source of the ultraviolet light and in communication with the controller, the battery having a voltage.
