Definitions

  • the invention relates to a display system configured for fixing to a fuel dispensing nozzle, the display system comprising an electronic display screen, a display controller connected to the electronic display screen, and a power source for providing electric power to the electronic display screen and to the display controller.
  • hand held fuel dispensing nozzles are used to dispense fuel, most likely, in a tank of a motorized vehicle.
  • the dispensing nozzle containing a spout which can be inserted into the opening of the tank in the vehicle, is connected through a hose with the fuel pumping system and the storage tank of the gasoline dispensing facility.
  • the nozzle itself is used to control the fluid flow after the spout is positioned into the opening of the tank in the vehicle.
  • the nozzle has an integrated valve which can be mechanically opened and closed on the costumers demand by using a trigger of the nozzle.
  • a known nozzle for a fuel dispensing system is disclosed in international patent application WO 99/44936 with title "Nozzle for a fuel dispensing system.”
  • the known nozzle comprises a display coupled to a control system to display information to a customer.
  • the display may display anything from transactional information to advertising and other information.
  • the nozzle also comprises a keypad to allow a customer to input information to the control system.
  • the known nozzle has a communication system capable of wireless, remote communication with an associated fuel dispensing system. Information may be transmitted from the dispenser to the nozzle to facilitate nozzle control or display to a customer, and information received at the nozzle may be transmitted to the dispenser for further processing or display.
  • the embedding material is a synthetic material.
  • the electronic components needed for driving an electronic display screen i.e., a controller and a power source are embedded in the embedding material.
  • the controller and particularly the power source are shielded from the outside of the sleeve and the controller and particularly the power source are at the same time shielded from the inside the sleeve, e.g. from the channel.
  • nozzles are no longer allowed to be fitted with a pin for keeping the trigger engaged while the spout of the nozzle is inserted in a car's tank inlet.
  • nozzles are now manually operated, typically by a costumer.
  • the costumer's visual attention is necessarily focused directly on the fuel nozzle itself, making the top of the fuel nozzle a desirable site for advertising.
  • the sleeve has an internal channel for receiving the fuel dispensing nozzle. Accordingly there is no need to modify the fuel dispensing nozzle in any way. This is very advantageous since fuel dispensing nozzles are certified. A modified nozzle would have to be certified again were it to be retrofitted with a sleeve. In fact, since at least a portion of the sleeve comprises an elastic material exercising a contracting force around the channel for pressing the sleeve against the nozzle so as to fixate the display with respect to the nozzle when the nozzle is fitted into the channel, there is no need to use any other type of fixing means. Fixing means such as screws, clamps and the like would impose a safety risk. Fixing means such as glue would impair servicing and repair of the display system.
  • the display system is very suitable for retrofitting an existing nozzle with a display screen.
  • Potential sources of ignition include electric sparks, electrostatic discharges, high-power electronics and hot surfaces. Since at least the display controller and the power source are embedded a potential spark emanating from them is retained inside the sleeve. Even if the potential for sparks is not reduced by the choice of sleeve-material in which the controller and power source are embedded, the risk of a spark is significantly reduced by retaining it in the sleeve.
  • the embedding material may be thermally conductive to improve heat conductance away from the electronics.
  • the display controller and the power source are embedded, that is fixed firmly in the surrounding mass of embedding material which is a close and snug fit. As a result of the embedding the display controller and the power source are an integral part of the sleeve.
  • the screen is integrated with the sleeve so as to form a one-part display system in which the screen is integrated.
  • the screen is at least partially embedded in the embedding material.
  • the sides of the electronic display screen may be embedded in the embedding material.
  • a back side of the screen may also be embedded in the embedding material.
  • the front-side may or may not be embedded in the embedding material.
  • Embedding the front-side in the embedding material has the advantage that the protection of the sleeve extends to the front-side of the screen.
  • Not embedding the front-side in the embedding material has the advantage that the display quality of the display system is improved.
  • the front side of a LED display, especially of an organic LED display screen is not considered a high safety risk.
  • the display controller and the power source are completely embedded; however, they may be enveloped by the embedding material from all sides except from one which is shielded by the electronic display screen.
  • the power source e.g., a rechargeable battery is completely embedded, i.e., embedded from all sides.
  • a spark emanating from the power source or controller is either stopped by the surrounding embedding material or by the display screen.
  • the power source may comprise a rechargeable battery having recharging means for charging the battery from a wireless energy source.
  • the recharging means would, e.g. be converting energy from a wireless source to energy stored in the battery.
  • the power source may comprise a rechargeable battery which is charged from an inductive source.
  • the inductive source may be close to a cradle of the fuel dispensing station to which the nozzle is attached through a hose.
  • a power supply comprising a non-rechargeable battery integrated in the sleeve is not feasible since electronic displays require relatively much power. Batteries with a high capacity, needed for a long standing operation impose a safety risk in a volatile environment. Furthermore the space for batteries in the sleeve is limited. Exchangeable batteries with smaller size and lower capacity are less suitable because they have to be protected which makes it complex en expensive to exchange.
  • the elastic material circumferentially surrounds a part of the channel. In this way the sleeve may be attached to the nozzle by an elastic force.
  • the embedding material is a flexible or/and stretchable material.
  • a flexible material the electronic components that are embedded in the flexible material are protected while the sleeve is fixed around the fuel nozzle.
  • An advantage of a flexible sleeve is that it may be pulled over the nozzle together with its integrated electronics.
  • the sleeve retains its flexibility when it is pulled over the nozzle.
  • PolyUrethane An example of a suitable flexible material is PolyUrethane.
  • the PolyUrethane may be colored into a desired color.
  • Other choices for the flexible material are possible.
  • the sleeve is a scuff guard.
  • the scuff guard protects the connection between the nozzle and the hose to which the nozzle is attached.
  • the connection is for example, a screwed connection.
  • the embedding material and the elastic material are the same material.
  • the portion of the sleeve which exerts a contracting force with an elastic material and the portion which embeds in a embedding material are formed as one-piece.
  • the sleeve entirely consists of the same material.
  • the material produces three advantageous effects with a single production step, first the non-conductive property of the material isolates the electronic parts from the surroundings by embedding them, second the elastic property acts as a means to fixate the sleeve to the nozzle, third the sleeve acts as a scuff guard, for protecting the connection between nozzle and hose.
  • the elastic material may also circumferentially surrounds a part of the channel
  • the sleeve is sufficiently flexible so that different shaped nozzles fit into the channel. This has the advantage that one sleeve design may be used for multiple nozzles of different designs.
  • the electronic screen is an organic LED display screen.
  • organic LED display screen require less power compared to LCD screens. Furthermore organic LED display screen have a broader operating temperature so that no additional heating or cooling features are required. For example, an OLED display screen may be used that can operate when external temperature ranges form -40°C to +70°C, without the need for heaters or coolers.
  • the low power light emitting diode display such as but not limited to an active matrix organic light emitting diode (AMOLED) display, comprises a substrate whereon a pixels of light emitting materials are sandwiched between thin electrodes. Since the light emitting material itself illuminates when power is applied to the corresponding electrodes, these kinds of displays do not require a backlight. Furthermore, an area on the display that should be black need not be illuminated and does not require energy. In comparison a regular LCD with backlight wastes power because the liquid crystal acts as a polarizer which filters half of the light emitted by the backlight. Therefore an organic LED requires less power in comparison with regular liquid crystal displays with backlight. In addition thereto organic LED display screen have a broader operating temperature so that no additional heating or cooling features are required. Therefore the low power light emitting diode display forms an integral part of the sleeve that can be completely encapsulated by a synthetic material.
  • the synthetic material could be PolyUrethanel.
  • the display such as the light emitting diode display, may be connected with a printed circuit board (PCB) to address the display.

  • the display controller may be mounted on a flexible PCB. The sleeve may be pulled over the nozzle together with its flexible integrated electronics, e.g., its flexible electronic display screen and/or flexible PCB.
  • a flexible display for example a display wherein the functional layers for the display are deposited on a transparent and flexible plastic foil such as polyethylenenaphthalate or polyethyleneterephthalate this problem is avoided.
  • the functional layers can be applied on a non transparent substrate as well and covered with a transparent layer.
  • the functional layers for the display are deposited on a flexible substrate such as a copper or steel foil.
  • the flexible display also offers more design freedom compared to a display containing a glass substrate.
  • the sleeve may be partially formed into three dimensional figures, e.g., for advertising purposes.
  • a flexible display is fitted more easily than a flat and rigid display.
  • the area where the display is placed may be half-cylindrical.
  • a flexible display further increases the vandalism resistance of the display system.
  • the sleeve is harder to pull back from the nozzle, since the rigid surface of the display is no longer available as a suitable target on which a force can be applied.
  • Having a flexible display, preferably together with a sleeve made out of a flexible material is particularly resistant to vandalism.
  • the display screen comprises a flexible display screen bended, such that a first portion of the display screen makes an angle with a second portion of the display screen.
  • the nozzle will be inserted along a bended path into a tank inlet.
  • the angle under which the screen is best visible may vary between different car brands.
  • the substrate on which the functional layers for the display are deposited is also used as an electronic circuit board comprising the display controller. In doing so all the electronic functions are build on one substrate by which a connection between the display and electronic assembly is eliminated. Reducing connections increases safety.
  • the embedding of the display controller and the power source is obtained by molding over.
  • the sleeve is used to form the scuff guard for the hand held fuel dispensing nozzle.

  • the display screen, power source and display controller form one part. This eases inserting of the electronics into a mold.
  • the display system further comprises a wireless receiver for receiving digital data for display on the electronic screen, the embedding material of the sleeve also completely embedding the receiver.
  • the wireless receiver may be used for receiving any one of firmware updates, digital data for processing and/or display on the display screen, in particular digital video data, and/or image data.
  • the wireless receiver is a wireless transceiver, i.e., a wireless transmitter and a wireless receiver combined together in a single unit.

  • a further aspect of the invention concerns fuel dispensing nozzle comprising a display system according to the invention.
  • the fuel dispensing nozzle is attached to a hose.
  • the hose comprises a wire for transferring power to a power transmitter for wirelessly transmitting power.
  • the power transmitter is arranged with respect to the power receiver so that power may be transmitted during operational use of the display system.
  • Power transmitter may be part of the hose or of the nozzle.
