A thief hatch state monitoring system includes a thief hatch sensor that detects a change in angular position of a thief hatch and generates sensor data at an output in response to the detected change. A processor having an electrical input is electrically connected to the output of the thief hatch state sensor. The processor determines when the angular position of the thief hatch changes by more than a predetermined amount from the sensor data and then generates a transmit signal indicating a state of the thief hatch. A network interface is electrically connected to an output of the processor. The network interface generates a signal that indicates the state of the thief hatch. A communication gateway includes a receiver that receives the signal indicating the state of the thief hatch. The communication gateway is electrically connected to a network that provides an end-user remote access to the state of the thief hatch.

The present invention relates to an anti-theft device for fuel tanks, wherein the anti-theft device comprises a pipe to be secured to a fuel inlet, wherein the pipe comprises attachment means at its upper portion, furthermore the pipe comprises at least one opening disposed in the side wall of the pipe, wherein the pipe is closed at a lower portion and that said pipe accommodates a substance, wherein said substance is adapted, in the event of a fuel theft attempt, to be carried with the fuel into the pump used during the theft attempt and thereby prevent continued pumping with it, and that the substance is further adapted to be incapable of leaking into the actual fuel tank.

The present disclosure provides a system for detection of one or more fuel pilferage events in one or more vehicles. The fuel pilferage detection system includes a first step of receiving a first set of data. In addition, the fuel pilferage detection system includes another step of collecting a second set of data. Further, the fuel pilferage detection system includes yet another step of analyzing the first set of data and the second set of data. The fuel pilferage detection system includes yet another step of categorizing the one or more vehicles in the plurality of categories based on the analyzing of first set of data and the second set of data. The fuel pilferage detection system includes yet another step of identifying the one or more fuel pilferage events in the one or more vehicles based on the analyzing of first and second set of data.

The fuel tank of a vehicle has a wail (26) and filling pipe (10) for adding fuel. The filling pipe has a mouth, through which there opens a connection into the fuel tank, The fuel tank comprises a protective cover (16) installed movably to the wall, the protective cover being movable to a first position in front of the mouth of the filling pipe and to a second position away from the front of the mouth of the filling pipe. The mouth of the filling pipe is usually covered by a releasable cap (14). When the protective cover is in front of the mouth, the cap in the mouth cannot be accessed and it cannot be removed from the end of the filling pipe. Respectively, when the protective cover is in the second position, it does not prevent or hinder the handling of the cap at the end of the filling pipe. The fuel tank can further comprise a locking element for locking the protective cover in place to the said first position. Preferably the locking element can be opened from the cabin of the vehicle.

A device for filling a fuel tank with fuel, comprising a tube formed member comprising an opening at a top end thereof for receiving fuel from a fuel nozzle, the tube formed member extending in a longitudinal direction of the device; and a fuel distribution member arranged to be provided inside the fuel tank and being connected to the tube formed member at a bottom end thereof, wherein the fuel distribution member comprises first and second plate elements which are spaced apart in the longitudinal direction and extend from the tube formed member in a radial direction thereof so that a space for fuel is formed between the first and second plate elements, wherein at least one of the first and second plate elements comprises perforations located in an area radially outside of the tube formed member for allowing fuel to enter the fuel tank.

Fuel anti-theft systems, apparatus, and methods. Embodiments provide fuel anti-theft systems including a circuit and sensors which define nominal (secure) and tampered-with states. The tampered-with states are indicative of the sensor(s) being absent. Controllers of the current embodiment, moreover, senses a combined state of (all of a pre-selected number of) the sensors and determines therefrom whether all of the sensors are present and secure. In some embodiments, the controller senses the sensors (which can be wired in parallel) via a vehicle chassis ground. If desired, a resistor (which is about electrically equivalent to one of the sensors) and/or a geo-positioning system can be connected to the controller. The sensors can include normally open switches and clamps, cable ties, adhesives, etc. which close the switches. Some sensors include grounding straps while others include ground return leads. In some embodiments, sensors are positioned at vehicle fuel caps and/or fuel filters.

An improved, secure, anti-siphoning method and apparatus that can be fitted into any size fuel tank. The present invention includes a re-configured fuel cap that includes an electronic display, a touchpad for numerically inputting a security code for allowing a user to unscrew the fuel cap. In addition, a biometric reader is implemented to read a user's thumb print, and subsequently allowing the user to access the fuel tank.

A fuel theft prevention system for a vehicle including: at least one processor; and a memory, operatively connected to the at least one processor and storing instructions that, when executed by the at least one processor, cause the system to: receive, from a first sensing system, first activity data; determine, based on the first activity data, a first confidence value indicative of whether the activity is suspicious; receive fuel data indicative of a fuel level in the fuel tank; and cause, based on the first activity data and the fuel data, at least one mitigation action to be taken when the fuel level decreases by a threshold amount, wherein the threshold amount includes a first amount when the first confidence value is a first value and a second amount when the first confidence value is below the first value, and wherein the second amount is greater than the first amount.
