Description

Liquid Dispensing
This invention relates generally to liquid dispensing, more specifically this invention relates to apparatus and method steps to dispense a liquid from a liquid source in a controlled manner. The invention also encompasses a method for distribution of electronic credits associated with liquid dispensing.
It is a basic human need to have access to water, other consumable liquids as well as other liquids such as liquid fuel. This liquid is accessed from a liquid source such as a mains service or from a large container such as a tank.
By way of a non-limiting example, water is the principal liquid of interest to be dispensed, but the skilled person will understand that the liquid could also be other consumable liquids as well as other useful but non-consumable liquids such as liquid fuel.
In some areas of the world, water is provided by main line water pipes, known as “mains water” and access to mains water is given by an authority usually in exchange for a payment, either by volume used or by length of time with access.
In areas of the world where there is no such mains water supply, a water source such as a large tank is provided. Payment is made to a central authority by volume of water dispensed from the source and this payment allows the water to be replenished once the source is depleted.
In developing countries, it is necessary that a community has good access to clean water, and in many communities it is necessary for the provision of a water source such as a large tank. This tank is accessed by a tap which can fill smaller containers which can then be provided to individual households. In order to control the use of the tap there is known generally to be a tap attendant. Problems faced by the communities in the developing world include the supply, logistics and maintenance of water services. These issues are highlighted by a report in 2014 from the World Bank after the 2012 “right to water” publication by the United Nations;
The human right to water entitles everyone to sufficient, safe, acceptable, physically accessible and affordable water for personal and domestic uses, UN CESC - General Comment 15, para.2
It is common in these community situations that payment for water is made by a household to a central authority which will then issue non-monetary credits or tokens to be used for water. The credit or token is worth a specific pre-defined volume of water and is given to the tap attendant for that pre-defined volume to be dispensed.
Apparatus in this community situation generally consists of a liquid source, a liquid flow control, and a volume indicator. In some situations, these parts are simply mechanical and in others the flow control and the volume indicator are electronic and partially or fully autonomous. There has not been previously provided an electronic or partially or fully autonomous replacement for the tap attendant or for the credit/token payment system.
Figure 1 demonstrates a known prior art approach to controlled dispensing of water, namely a card 10 issued to households upon pre-payment for water. The card 101 includes; a number of credits in the form of scratch-off panels 102 which when handed to a tap attendant will be removed to indicate usage, and instructions for use 104. When a card is presented to the tap attendant, one panel is scratched off to reveal an image representing one unit 103 and so one unit volume of water is provided. After every panel has been removed, the card is retained by the tap attendant who uses it to claim his wage from the central authority. This is a ‘low tech’ solution to resource control. Problems with this system reside in distribution of credits, retention of the cards and the wage and position of the tap attendant.
There has been a need professed by the World Bank in November 2014;
The most critical game changers are the increasing use of information and communication technologies (ICT) to eliminate cumbersome token usage and link prepaid meters to mobile phones and vendors.
Prepaid water needs to be taken far more seriously in water sector policies and regulatory frameworks and in scaled-up technical support to optimize the opportunities they offer and the risks they pose.
(http://www. worldbank, org/en/news/feature/2014/09/01/assessment-of-eight-african-citiesexplores-limitations-and-possibilities-of-prepaid-meter-systems accessed in April 2015)
It is an aim of the present invention to provide a solution to the logistics of payment, credit management and dispensing problems identified above and to provide a solution to the needs professed by the World Bank.

Presented herein is a pre-paid liquid such as water dispensing apparatus to help manage principally water provision for communities in developing areas. It is understood that this invention may also have other applications in other areas.
The largest problem in the developing world at the moment, as illustrated by the World Bank, is that even though water systems are being installed, they often aren’t sustainable. The water usage needs to be managed and paid for. The apparatus in one embodiment could simply attach to a pre-existing stand pipe and be powered by a solar collector but it is understood that it also could be newly installed and powered by other means such as a battery. The device operation is conducted via Near Field Communication (NFC). NFC is a protocol for the transfer of data and NFC devices can be powered or unpowered. In preferred embodiments the NFC device is an unpowered key fob but it could also be an unpowered card or a powered mobile device such as a mobile phone. These devices are capable of holding small amounts of editable and readable data. Such key fobs can be loaded up with a set amount of water credit to deliver a predefined volume of water. When the key fob is held near the water dispensing apparatus it will dispense water until the key fob is taken away or until credit runs out. In such embodiments, further credit can be provided for the key fob via NFC transfer from a powered mobile device. The powered mobile device receives credit after payment through SMS or by NFC contact with other powered or unpowered devices. Personal management of credits is conducted via a mobile phone application on a powered NFC device such as a mobile phone. The mobile application allows NFC transfer of credits and also manages a personal wallet.
Embodiments of the invention will now be described purely by way of non-limiting example only with reference to the accompanying drawings in which:
Figure 1 is a schematic view of a Prior Art payment scratch card;
Figure 2a is a near field communication key fob;
Figure 2b is a near field communication card;
Figure 2c is a powered mobile device that includes an NFC circuit
Figure 3 is a liquid dispenser
Figure 4 is a detail view of a portion of a liquid dispenser
Figure 5 is a detail view of a control board of the liquid dispenser
Figure 6 is a flow diagram describing a method for dispensing
Figure 7 is a flow diagram describing a method for credit distribution
Figures 2a, 2b and 2c show three specific embodiments of the NFC enabled devices that store and transfer credits used for dispensing a liquid. Figure 2a shows an unpowered NFC key fob 21 that includes an NFC circuit represented by the NFC logo 210. Figure 2b shows an unpowered NFC card 22 that includes an NFC circuit represented by the NFC logo 220. Figure 2c shows a powered mobile device 23 that includes an NFC circuit as a part of its standard features.
The unpowered NFC devices 21 and 22 store credits and are used to dispense a liquid from a liquid dispenser equipped with an NFC reader. The unpowered NFC devices 21 and 22 are placed against the NFC reader on a dispenser which debits credits from the device and dispenses a pre-defined volume of liquid.
The powered mobile device 23 can connect to the internet or to a local computer network and monitors the credits associated with a user’s account. The powered mobile device 23 can be positioned against the NFC key fob 21 or the NFC card 22 in order to transfer credits, an application installed on the mobile device facilitates the process allowing authentication via a computer network and controls the number of credits transferred. The powered mobile device also has the function of a device to dispense liquid, the powered mobile device is placed against the NFC reader on a dispenser which debits credits from the mobile device and dispenses a pre-defined volume of liquid.
NFC devices 21, 22 and 23 replace the owned portion of the apparatus previously the card 101 in figure 1.
Figure 3 demonstrates apparatus for dispensing a liquid 30. The apparatus comprises a control unit 302, a drain 304, a solar collector 306 and an NFC communication point 308. The control unit allows for the distribution of a liquid in exchange for a pre-purchased credit stored on an NFC storage device. A user will position an NFC storage device on the NFC communication point in order to dispense a pre-defined volume of liquid. The apparatus is powered by a solar collector 306, although other or supplementary power supplies are envisaged.
Figure 4 demonstrates a detail view of a control unit for a liquid dispenser 40 and comprises an NFC communication point 402, a liquid inlet 404 to be in communication with a liquid source (not shown), a liquid outlet 406 for discharge of metered prepaid volumes of water, a unit on the liquid line to control flow comprising a latch solenoid 408 and a Hall Effect meter 41 Oto monitor usage. The figure also depicts a control board 412 and a power source 414. In this figure the casing appears transparent merely for purposes of better illustration and explanation.
Figure 5 depicts a control board 50 (e.g. the control board present in the figure 4 arrangement) for a liquid dispenser and comprises an NFC circuit 502, LEDs 504, power in 506, hardware and software for managing data, connection points 508 for a latch solenoid and connection points 510 for a Hall Effect meter. Optionally, this control board also comprises means (not shown) to connect to a network.
Figure 6 demonstrates a process 60 by which a liquid dispensing apparatus according to a first aspect of the invention can control the distribution of a liquid. The default status 602 of the apparatus is OFF and every two seconds 604, the apparatus checks the presence of an NFC card 606, if no, the process begins again, if yes, the data on the card is read 608. If there is an error, the user is notified and the process begins again. The apparatus has encryption/decryption capabilities and in order to dispense liquid, the dispensing apparatus needs to decrypt 610 the data from the card. Decryption will demonstrate the credit available on the card 612 and if the credits total one or more 614, the tap is turned on, if the credits are zero the process begins again. The Dispensing apparatus has flow rate control means allowing the dispensing of a predefined volume of liquid 618. If there is an error on the tap, if the liquid source is empty or if there is a blockage in the pipe, an error is recorded and the process begins again after notification is made to the user and to a central authority. If there is no error and liquid is dispensed, the account of the user is debited a predefined number of credits and the process begins again. If more liquid is required, the user can leave the NFC card in contact with the NFC reader to dispense another volume of liquid.
Figure 7 demonstrates a process 70 of transferring pre-paid water volume credits. A central controlling authority with a data centre 702 generates and distributes credits. This central authority may be in a large town or city and local distributors make contact with them, either in person or remotely via mobile communication. Credit transfer is effected either over a network or via NFC transfer between the data centre and a primary mobile device with NFC capabilities upon payment. A large volume 704 of credits are transferred to the local distributor and are stored on a primary powered mobile device 706. The local distributor then becomes available to a smaller local community 710 where apparatus 718 for distributing a liquid through NFC means is provided. The local distributor can then transfer a small portion of their credits (retained on the powered mobile device 706) to local individuals and families within that community and is paid for doing so in order to reimburse the initial purchase. There is an option for the cost per credit to be the same as the initial purchase or different therefrom if there are subsidies or if the local distributor is earning a wage. The credits are stored on secondary storage devices 714 including other powered mobile devices, NFC key fobs and NFC cards. Each credit represents a pre-paid predefined volume of liquid 716 and when the secondary storage device 714 actuates the apparatus 718 for distributing a liquid via NFC contact that said volume is dispensed into a suitable container as indicated schematically.
It will be appreciated by those skilled in the art that any number of combinations of the aforementioned features and/or those shown in the appended drawings provide clear advantages over the prior art and are therefore within the scope of the invention described herein.
