6 PCT/EP2016/055864 BRIEF DESCRIPTION OF THE FIGURES
The present invention will now be described with reference to the accompanying Figure 1 which shows a schematic of the present invention.
DETAILED DESCRIPTION
With reference to Figure 1, there is shown an assembly 10 comprising a valve 100 connectable to a cylinder body 102 for a pressurised fluid. The valve comprises a valve element movable between an open position in which fluid can escape the cylinder, and a closed position in which the fluid is contained within the cylinder.
Electrically connected to the valve 100 are a CPU 104 and a sensor 106 for monitoring a parameter of either the valve, fluid in fluid communication with the valve, a fluid in the cylinder, and/or the environment around the cylinder 102.
The parameter monitored by the sensor 106 may be, for instance, the duration that the valve element is open, the quantity of fluid flowing through the valve, leakage from the valve, ambient temperature and/or pressure around the cylinder, and/or the number of opening cycles the valve element makes. The sensor 106 may alternatively be a microphone. The CPU 104 and sensor 106 may be powered by any appropriate power source 108. Dependent on the value of the parameter measure by the sensor 106, signals from the sensor 106 may be transmitted via the CPU 104 to control the operation of the valve element.
The valve assembly 10 also comprises a wireless signal receiver 110 for receiving an electronic signal from a remote location as will be described. The wireless signal
The present invention will now be described with reference to the accompanying Figure 1 which shows a schematic of the present invention.
DETAILED DESCRIPTION
With reference to Figure 1, there is shown an assembly 10 comprising a valve 100 connectable to a cylinder body 102 for a pressurised fluid. The valve comprises a valve element movable between an open position in which fluid can escape the cylinder, and a closed position in which the fluid is contained within the cylinder.
Electrically connected to the valve 100 are a CPU 104 and a sensor 106 for monitoring a parameter of either the valve, fluid in fluid communication with the valve, a fluid in the cylinder, and/or the environment around the cylinder 102.
The parameter monitored by the sensor 106 may be, for instance, the duration that the valve element is open, the quantity of fluid flowing through the valve, leakage from the valve, ambient temperature and/or pressure around the cylinder, and/or the number of opening cycles the valve element makes. The sensor 106 may alternatively be a microphone. The CPU 104 and sensor 106 may be powered by any appropriate power source 108. Dependent on the value of the parameter measure by the sensor 106, signals from the sensor 106 may be transmitted via the CPU 104 to control the operation of the valve element.
The valve assembly 10 also comprises a wireless signal receiver 110 for receiving an electronic signal from a remote location as will be described. The wireless signal
-7-receiver can be configured to receive signals over any conventional wireless transmission method, for instance Bluetooth, UHF and GSM. The wireless receiver 508 could additionally allow for non-wireless communication signals to be received, for instance by being provided with a USB port.
Each receiver could alternatively be a transceiver to allow signals to be emitted, as well as received, from the valve assembly 10.
A control panel 300 is located in a location remote from the valve assembly 10. The control panel 300 is connected to a wireless signal emitter 302 (which alternatively may be a transceiver), and may be connected to an input device 304 and/or a computer network 306.
A relay station 400 may be provided to relay signals between the valve 100 and the control panel 300. The relay station comprises at least one wireless transceiver for communicating signals to and from the valve 100 and the control panel 300.
Signals between the control panel 300, the relay station 400, and the valve 100 may be communicated and/or stored in the cloud 200.
The purpose of the control panel 300 is to allow remote operation of the valve assembly 10 and any other valve assembly (for instance valve assembly 10' as shown in Figure 1) that the control panel 300 can send a wireless signal to.
In one embodiment, a wireless signal may be sent from the control panel 300 to some or all of the valve assemblies
Each receiver could alternatively be a transceiver to allow signals to be emitted, as well as received, from the valve assembly 10.
A control panel 300 is located in a location remote from the valve assembly 10. The control panel 300 is connected to a wireless signal emitter 302 (which alternatively may be a transceiver), and may be connected to an input device 304 and/or a computer network 306.
A relay station 400 may be provided to relay signals between the valve 100 and the control panel 300. The relay station comprises at least one wireless transceiver for communicating signals to and from the valve 100 and the control panel 300.
Signals between the control panel 300, the relay station 400, and the valve 100 may be communicated and/or stored in the cloud 200.
The purpose of the control panel 300 is to allow remote operation of the valve assembly 10 and any other valve assembly (for instance valve assembly 10' as shown in Figure 1) that the control panel 300 can send a wireless signal to.
In one embodiment, a wireless signal may be sent from the control panel 300 to some or all of the valve assemblies
-8-10;10' which instructs the valve 100;100' of these assemblies to close.
The wireless signal from the control panel 300 is transmitted via the emitter 302 to each of the valve assemblies 10;10' either directly, via the cloud 200, or via the relay station 400.
Sending of the wireless signal may be triggered by depression of the input device 304, which may be for instance an emergency stop button. Such an input device 304 may be provided in addition to a further, separate controller for controlling the normal operation of the valve 100 (i.e., non-emergency use).
For example, each valve 100 of a plurality of valves 100 may be provided with a first controller, whilst a single input device 304 may be provided for emergency shut off of all of the plurality of valves 100.
The signal may alternatively be triggered by a fire alarm going off, or a smoke detector triggering. The signal may also be triggered based on a command from the computer network 306 which is connected to the control panel 300.
Another situation in which the signal may be triggered might be when the facility containing the valve assemblies 10'10' is shut for the day. In this case, it may be desirable to send a signal via the control panel 300 to the valve assemblies located within the facility to ensure that none of them have accidently been left open. For this purpose, the control panel 300 may comprise a time switch that provides a signal indicating a predetermined time so that

For this purpose, the control panel 300 may comprise a time switch that provides a signal indicating a predetermined time so that
-9-the control panel can be triggered to transmit the signal at the predetermined time.
The signal may alternatively be triggered in response to a voice command from an operator next to the control panel, or in response to a measured parameter of the conditions surrounding one/all of the valves. This measured condition may be the temperature around the monitored valve(s); the pressure around the monitored valve(s); and/or the chemical composition of the environment around the monitored valve(s).
It will be appreciated that modifications could be made to the assembly 10 described above without departing from the scope of the invention.
In one embodiment the sensor 106 may communicate with the CPU 104 and the valve 100 and serve as a mechanism which keeps the valve closed to personnel who are not authorized to use the valve. Such embodiments have particular application in the medical field in which it is very important to restrict access to certain fluids such that only qualified/authorised individuals can use these.
A shut-off valve in accordance with such an embodiment may comprise a sensor 106 that is electronically arranged to provide the authorisation signal to the CPU 104 and to sense data that can be used to authenticate a user. The controller 104 may be arranged to allow the valve element to move from the closed position to the open position only if the authorisation signal indicates that the user is authenticated.
The signal may alternatively be triggered in response to a voice command from an operator next to the control panel, or in response to a measured parameter of the conditions surrounding one/all of the valves. This measured condition may be the temperature around the monitored valve(s); the pressure around the monitored valve(s); and/or the chemical composition of the environment around the monitored valve(s).
It will be appreciated that modifications could be made to the assembly 10 described above without departing from the scope of the invention.
In one embodiment the sensor 106 may communicate with the CPU 104 and the valve 100 and serve as a mechanism which keeps the valve closed to personnel who are not authorized to use the valve. Such embodiments have particular application in the medical field in which it is very important to restrict access to certain fluids such that only qualified/authorised individuals can use these.
A shut-off valve in accordance with such an embodiment may comprise a sensor 106 that is electronically arranged to provide the authorisation signal to the CPU 104 and to sense data that can be used to authenticate a user. The controller 104 may be arranged to allow the valve element to move from the closed position to the open position only if the authorisation signal indicates that the user is authenticated.
- 10 -The sensor 106 may be an RFID or NFC tag reader such that the valve 100 can only be operated if a particular RFID or NFC tag (supplied to an authorized person) is within the vicinity of the RFID or NFC tag reader. In this way, the sensor would only output a signal indicating that a user is authenticated when the correct RFID or NFC tag is nearby.
Optionally, the presence of the tag may trigger the controller 104 to allow the valve element to move from the closed position to the open position for a predetermined period of time, following which the controller will move the valve element from the open position to the closed position.
The tag may be presented to the device again when that time period has expired to again authenticate the user.
Alternatively, the presence of the tag may trigger the controller 104 to allow the valve element to move from the closed position to the open position until a predetermined quantity of fluid has been dispensed from the cylinder, following which the controller will move the valve element from the open position to the closed position. The tag may be presented to the device again when that quantity has been dispensed to again authenticate the user.
In a preferred version of this embodiment, the RFID or NFC
tag can be used as a payment device, such that the user makes a payment each time the device authenticates the user.
In this way, a user can pay for the provision of stored fluid.
The sensor 106 could alternatively be a biometric reader, for instance a fingerprint scanner, responsive to a biometric from an authorized person. In this way, the sensor

The sensor 106 could alternatively be a biometric reader, for instance a fingerprint scanner, responsive to a biometric from an authorized person. In this way, the sensor
-11-would only output a signal indicating that a user is authenticated when the correct fingerprint is presented.
The sensor 106 may comprise a socket and be arranged to sense the insertion of an electronic key therein. In this way, the sensor would only output a signal indicating that a user is authenticated when the correct electronic key is inserted.
An indication means, for instance in the form of a visual display or a speaker, may be electronically connected to the CPU 104 on the valve. The indication means would be operable to emit a first indication upon an authorized person being allowed access to the valve, and a different indication in response to an access attempt from an unathorized person.
The sensor could alternatively be used to sense the position of a component of a mechanical lock. In this way, the sensor would only output a signal indicating that a user is authenticated when the mechanical lock has been unlocked.
A data logger may be electronically connected to the CPU 104 for monitoring which authorized and/or unauthorized personnel operate the valve, and when. Data from the logger may be stored in a memory, or may be sent by a wireless transceiver 110 on the valve to a remote location, for instance the control panel 300 or the cloud 200.
