[0001] Cross - Reference to Related Applications
[0001] This application claims priority to U.S. Provisional Patent Application No. 63 / 339,832, filed May 9, 2022.
[0002]
[0002] This application generally relates to multi - component systems for removing contaminants from articles, enclosed spaces, and unenclosed spaces, and more particularly to removing microbiological contaminants from such locations.
Background Art
[0003]
[0003] Microbial species are widely distributed in our environment. Most microbial species cause few problems as they do not harm other organisms. However, other microbial species can infect humans or animals and cause harm to them. The removal of microorganisms, as well as the decontamination of articles and spaces from them, has been of interest for a long time. Drugs and medical devices are sterilized and packaged in sterile containers. Medical environments, such as operating rooms, hospital wards, and examination rooms, are decontaminated by various cleaning procedures so that the microorganisms of concern cannot spread between patients.
[0004]
[0004] Many available techniques for controlling microorganisms are valuable in the context of biological warfare and bioterrorism. Further, existing decontamination techniques have limited effectiveness in enclosed environments.
Summary of the Invention
Problems to be Solved by the Invention
[0005] Addressing the timing, duration, and control of the contamination removal process is technically difficult. Control systems often rely on many people on-site to monitor and implement the contamination removal process. Furthermore, systems for controlling the contamination removal process are neither scalable nor modular. As a result, the contamination removal process typically requires a redesign of system control depending on the nature of the contamination removal process. Considering the above, there is an urgent need for a scalable and modular system that can provide high awareness of the time of the contamination removal process and high awareness of the environment even when there is no person on-site.

The present application relates to a method.
[0032] System Architecture
[0038] One aspect of the present application is a multi-configuration spray misting contamination removal control system. The control system is a multi-component application that controls hardware. The control system utilizes a plurality of application subsystems to perform its functions. The control system is designed for local and remote operation and uses a small application runtime that is controlled by a front-end web experience.
[0033]
[0039] The control system is designed to run independently or be connected to a network. An IP connection via wireless (WiFi / Bluetooth) or wired connection is used to facilitate the connection of the control system. IP address assignment can be configured at the operating system level via a browser interface. The control system operation is managed by an application runtime, a system controller, and a web service layer. The components of the system may include a mobile and web application framework, an Internet of Things (IoT) board for input / output (I / O) devices, user authentication and identity management, a high-speed web server, a high-speed Java script web runtime, a node package manager, and a general-purpose operating system (e.g., Linux, etc.).
[0034]
[0040] In an exemplary embodiment, a computer system includes a memory, a processor, and optionally, a secondary storage device. In some embodiments, the computer system includes multiple processors and is configured as multiple, for example, blade servers or other known server configurations. In certain embodiments, the computer system also includes an input device, a display device, and an output device. In some embodiments, the memory includes RAM or a similar type of memory.

These applications preferably include executable instructions for implementing the functions and methods described herein. The application preferably provides a GUI through which a user can view and interact with the application. In other embodiments, the system provides remote access for controlling and / or viewing the system.
[0035]
[0041] The control system is a computer-implemented control system that can send a contamination removal process to rooms and other areas using various applicators. FIG. 1 shows an embodiment of the architecture of the system components and their relationships. In this embodiment, the control system utilizes a general-purpose computer. The control system is operated by a general-purpose computer. A general-purpose computer does not require dedicated hardware and provides the greatest flexibility in programming languages, development environments, and software and accessory support. Further, a general-purpose computer provides reliable I / O, an easily installable operating environment, and the lowest cost.
[0036]
[0042] The general-purpose computer interfaces with sensors, event signals, and contamination removal solution applicators via a plurality of control boards. Those skilled in the art will understand that the number of applicators does not limit the system. In one embodiment, the system uses up to 20 applicators. However, other embodiments may use up to 5 applicators, up to 10 applicators, up to 15 applicators, up to 30 applicators, up to 40 applicators, up to 50 applicators, up to 100 applicators, etc. The number of applicators used is ultimately determined by the scale of the contamination removal project required. For example, a contamination removal system suitable for a large multi-story office building may have multiple applicators on all floors. The control system described herein supports all configurations and supports individual manual operations, event-driven control, and remote control operations. In a preferred embodiment, the applicator uses a binary ionization technique for contamination removal that ionizes hydrogen peroxide using high voltage current to remove contamination from the area. The applicator is available as a portable unit for removing contamination from surfaces using a handheld applicator, an environmental unit that is a transportable device in a case, and a fixed unit that is centrally installed and controlled in a substantially enclosed space (e.g., within an office building or a research facility).
[0037]
[0043] The general-purpose computer is network-connected to the operator device and the local administrator workstation. The operation of the control system can be controlled using any operator device equipped with an appropriate web browser. In certain embodiments, the operator device may be physically integrated with the general-purpose computer (2). In other embodiments, the operator device may be remotely linked to the general-purpose computer via a wireless network connection. In certain embodiments, the control system is designed to be remotely operated via its web application. The application software is designed to be extensible by exposing a software development kit (SDK) that can be used to build extended applications without the need for software redeployment. The SDK provides the ability to access the control system using Representational State Transfer (RESTful) web services to support remote and custom applications.
[0038]
[0044] In some embodiments, the local administrator workstation is network-connected directly to the general-purpose computer via an appropriate cable. In other embodiments, the local administrator workstation may be remotely linked to the general-purpose computer. In certain embodiments, the local administrator workstation may not be included, or in alternative embodiments, the operator device may be used as the local administrator workstation. The general-purpose computer is also connected to a third-party administrator workstation via an Internet connection, which may be used by a third party responsible for the maintenance of the control system and the supervision of decontamination operations. In certain embodiments, the third-party administrator workstation is not included, or in alternative embodiments, the third-party administrator workstation is the operator device. The general-purpose computer is also connected to an inventory server, an analysis server, and an application server via an Internet connection.
[0039]
[0045] In one embodiment, the control system runs on a general-purpose computer on a single board (substrate) in which RAM, I / O, and a chipset are embedded. In certain embodiments, the general-purpose computer consists of a single substrate that can be easily attached to a container.
[0040]
[0046] The control system interfaces with several sensors, switches, and event-driven mechanisms. In one embodiment, the computer hardware design incorporates a control board for the sensor package. The applicator is connected to a general-purpose computer by the sensor package. The sensor package is controlled using an off-the-shelf control board having multiple general-purpose I / O ports (GPIO) that can be used to interface with multiple devices. The board is designed to support the Internet of Things (IoT) and can be easily flashed with custom software or controlled externally. The control board interfaces with the control system via USB and is controlled using a dedicated serial driver loaded by the operating system. The control board is programmable so that it can be easily configured to support data from most conceivable sensors that provide flow meters, temperature, humidity, light level, and voltage, pulse, frequency, digital, or current outputs. It can also provide digital and analog outputs, as well as PWM (pulse width modulation) outputs for controlling many types of actuators (e.g., a contamination removal device that applies a spray mist to a space or article for contamination removal) and devices. To support the connection to the general-purpose computer, a small application is executed on the control board to manage the low-level interface and any necessary data normalization. The application makes available a series of commands executed from the main system controller via the USB connection. These commands provide maintenance testing of sensors and actuators, reading of sensor data, and control of output actuators. Optionally, an interface printed circuit board (PCB) is added to simplify the connection between the control board, the control system flow meter, the applicator hardware, and any additional temperature or humidity sensors.
[0041]
[0047] In an exemplary embodiment, the control system is executed on an Ubuntu Linux operating system (e.g., open source software). Ubuntu is used on desktops, server hardware, and embedded systems. Although Ubuntu is not a real-time operating system, it can measure short time slices and is highly responsive. Ubuntu is hardened by enabling the installed firewall, ufw, and closing all unnecessary ports.
[0042]
[0048] In certain embodiments, Secure Shell (SSH) access is the primary means of direct access to the computer and is mainly used for installation and deployment, as well as upgrading various software components such as the operating system. Certain configuration settings may be set at the operating system level. These settings typically include date and time and management authentication (LDAP). In certain embodiments, automatic time synchronization and sendmail configuration are the only two settings that are recommended to be set at the operating system level.
[0043]
[0049] Normalization and filtering of data are also performed in this module, providing clean sensor data to the main controller of the system. The platform can interface with a computer system or a circuit board via a standard USB interface. This interface appears as a virtual serial port (COM port) to the main controller. The virtual serial port simplifies issuing commands between the computer and the underlying hardware at the software level. Commands and responses are transmitted between the computer driver and the hardware as ASCII text. Almost all modem languages and runtimes support the transmission of ASCII text via the COM port.
[0044] End-user implementation process
[0050] The control system software follows a layered architecture approach. Applications, interfaces, and their services are built on top of support components and frameworks that provide abstractions from lower-level functionality. This approach provides maximum flexibility for deploying updated software and installing new components. This is possible because the layers of abstraction allow changes to the implementation of support services and subsystems without requiring updates between layers, unless absolutely necessary.
[0045]
[0051] Figure 2 shows an embodiment of a layered architecture. The architecture consists of six layers. The first layer that the user interfaces with includes six subsystems including warnings, configuration, devices, events, reports, and a software developer kit. The second layer is a system controller that is a general-purpose computer. The third layer is an application programming interface (API) gateway that network connects the general-purpose computer to other components of the system. The fourth layer is a web application where network communication within the system occurs. The fifth layer is an application runtime that executes instructions communicated within the system. The sixth layer is a programming language.
[0046]
[0052] The system controller provides an abstraction layer between the characteristics and functions of the control system and the application. The system controller controls the system. Designed as an intermediate-level component that is memory-loaded and accepts commands from internal and external systems, the system controller maintains state and manages the system configuration. It operates in its own process space and runs as a fault-tolerant self-service. It is configured to be automatically enabled and starts automatically when the computer boots. The system controller manages the start-up and stop operations of the control system. The system controller interfaces with multiple subsystems to manage control system operations. The interface with the subsystems is restricted in that the system controller does not directly access the underlying low-level hardware, reporting, configuration, or other subsystem implementations. These abstraction layers provide a flexible architecture that gives the user the ability to switch hardware or change the implementation of any subsystem without requiring major (or any) changes to the operation of the system controller or the control system. As described above, the system controller itself abstracts the API gateway and web server components, allowing them to be upgraded or changed without requiring significant rework or changes to other components.
[0047]
[0053] The web server component supplies commands for the control system and the web application used as the control system. The operator provides a username and password, logs in to the control system to make configuration settings, starts the execution of the application, and downloads reports and logs.
[0048]
[0054] In general, all application-specific configuration parameters and access to functions are made available via a web application. This includes event dispatching, time and timer-based operations, report generation configuration, as well as the ability to specify room / application profiles and user access. Configuration parameters and layouts are determined in the web application user interface design and style guide documentation.
[0049]
[0055] Figure 3 shows an exemplary embodiment of an end-user interface and an administrator interface. The interface supports both polling and interrupt or exception-based reporting to the main system controller. The login screen is first presented to request the user's authentication information to reach the system's home page. Options are provided to start a decontamination cycle. Control and setting options enable recipe configuration, calibration, priming, control, and setting parameters to be adjusted. Recipe configuration enables recipe selection, room dimension adjustment, spray cycle setting, RABS and LAF setting, time countdown, and H2O2 sensor reading set points. Room descriptions enable manual descriptions of each room to be decontaminated. Calibration enables dose verification and fluid velocity calibration for each applicator. Applicator priming enables the selection of applicators to be primed at high or normal speeds. Safety questions can be enabled or disabled and text can be modified. Manual control of pumps and valves is performed for each applicator. Control of the flow meter enables the selection of a gear pump or flow meter for each applicator. System settings enable functions to be enabled or disabled and date and time adjustment. Parameters for aborting set points may be set to achieve tolerance for abnormal occurrences. User management enables new users, user level setting, and passwords.
[0050]
[0056] When the cycle start button is pressed, a recipe must be selected for execution. Explanation and allowable questions require selection if the function is enabled in the settings. When all permissions are satisfied, the "Cycle Start" button is displayed. The execution screen displays all cycle information when started. The report screen shows report information regarding the progress of each cycle after the cycle has ended (regardless of whether it was successful or not).
[0051]
[0057] The system monitors the supply of the contamination removal solution via a contamination removal solution indicator. When the contamination removal solution storage tank requires a large amount of fluid, a "Low Tank Level" message is displayed in yellow on the login and home screens. If the shortage of the contamination removal solution is not addressed, a message of "Reservoir Tank is not filled" is displayed in red. To clear the message, the user must select "Pump Control" in the control and settings menu and activate the fluid pump until the "High Level Status" indicator turns green. (To prevent recurrence, it is necessary to address the shortage of the contamination removal solution amount).
[0052]
[0058] In certain embodiments, the hardware interface commands may include instructing self-tests of all connected sensors with pass or fail responses, calibration processes for all sensors, reading and displaying current sensor values for each sensor, setting sampling rates for each sensor, setting scaling parameters for each sensor, self-tests of all connected actuators, controlling calibration processes of actuators, setting output change rates of actuators, energizing actuators, de-engaging actuators, setting all parameters for suggested defaults, and clearing all settings.
[0053] Computer-implemented process
[0059] One aspect of the application is a control system that is a software application for controlling hardware. Thus, the software needs to be fast, responsive, and react to external signals and events. The control system software is constructed to occupy a very small footprint and uses a simplified design consisting of an application runtime and multiple systems that support control system functions.
[0054]
[0060] Figure 4 shows an embodiment of a high-level computer system architecture. The application runtime consists of three primary services: an API gateway used for standardized access to the control and configuration of the control system, a low-level system controller, and a web server that provides user remote access. Both the API gateway service and the web server service utilize the system controller to make configuration changes, calibrate sensors, and control the system. The application runtime uses many services to carry out its work. Each service is designed to be fault-tolerant in that it automatically restarts after a failure and is configured to start automatically at boot time.
[0055]
[0061] The API gateway constitutes and controls a pollution removal control system and functions as an application endpoint for all internal and external systems. The API gateway is an executable service installed on a computer and accessible via an IP address and port number. Internal applications and systems refer to the API gateway in the same way as external services, except that all internal communications are connected via the local host. The API gateway can be started and stopped independently and provides the ability to update its software. The API gateway is stateless, which means that it accepts incoming requests and processes them without saving local data. It exposes several RESTful services that are mapped to configuration and control functions, as outlined by the feature set. The API gateway provides a cost-effective platform that enables the system to be extended without significant re-engineering. The main means of communicating with a general-purpose computer is via its API gateway. The API gateway exposes many endpoints used in configuration, as well as in monitoring and data capture. Two-way communication is facilitated via webhooks for any application that requires asynchronous delivery of data from the control system.
[0056]
[0062] Figure 5 shows an embodiment of an application runtime organizational block diagram. A user is linked to a system controller and subsystems via an API gateway by a web server. The API gateway also provides network links to web applications and other servers, etc.
[0057]
[0063] Furthermore, in the embodiment shown in FIG. 4, there are also subsystems, which are warnings, configurations, devices, events, reports, and the software developer kit is also part of an application database on a general-purpose computer. Furthermore, the subsystems are connected to a sensor pipeline linked to an applicator and a set of sensors via a driver interface.
[0058]
[0064] The subsystems of this specification are a set of lowest-level execution components that directly access the features and functions of the hardware. Each subsystem is designed for a major grouping of features within the environment.
[0059]
[0065] In one embodiment, the general subsystem design comprises each subsystem having two interfaces. One interface provides a high-level abstraction optimized for applications and higher-order programs, and this interface links the system controller to the subsystem. This interface is essentially bidirectional, meaning that the subsystem accepts and executes functions. The second interface is a low-level unidirectional interface that communicates with the underlying hardware or is specifically used to deliver low-level functions.
[0060]
[0066] The subsystems are intentionally designed to be autonomous components. This provides the ability to make software changes to a particular subsystem and apply patches to the solution for a single subsystem without having to make monolithic changes to the solution.
[0061] Warning subsystem
[0067] The warning subsystem is used to process all outgoing messages from the control system.
[0062]
[0068] Warnings are implemented as messages having a body consisting of a recipient address, a sender address, and UTF-8 text. Warnings may include simple text, an email message to a designated recipient or list, and notifications within application services and other subsystems.
[0063]
[0069] Email notifications require a specified mailbox and SMTP configuration. The operator uses a configuration application accessible by a web browser to set the SMTP parameters including mailbox, username, and password credentials. Emails can be delivered programmatically using the built-in send email application or using Javax or NodeJS libraries.
[0064]
[0070] The subsystem and internal services utilize the warning subsystem by registering themselves as publishers and stating the type of message and delivery mechanism. The internal services can register warnings by registering themselves as observers for specific messages of the subsystem. A common producer / consumer design pattern is used to automatically dispatch messages to interested parties.
[0065]
[0071] External systems that require warnings also utilize the warning subsystem. The same mechanism is used to register themselves as message recipients, except that external services use the RESTful service interface of the API gateway. The external service must supply a webhook that can be called by the warning subsystem. This means that the external service is technically a consumer and a producer.
[0066]
[0072] In certain embodiments, external warning systems including SMS are not supported but can be implemented using RESTful web services or other means.
[0067]
[0073] The producer / consumer model used in the warning subsystem is designed in a general way so that it can be reused in other control system components that require a registration and publishing framework.
[0068] Configuration Subsystem
[0074] The configuration subsystem is a command processor for storing and changing configuration values within the system.
[0069]
[0075] The configuration subsystem stores its values using an embedded database. A runtime database that runs in its own thread and process space is avoided. A separate runtime database increases the complexity of installation and deployment. Most file-based embedded databases can handle gigabytes of data and millions of records, which is more than sufficient for a control system. Additionally, the embedded database provides simple backup and restore methods.
[0070]
[0076] In most cases, configuration parameters are stored as key-value pairings. In certain cases, configuration parameters may be stored as objects. In some cases, the configuration is stored as JSON or XML, and these values are stored as BLOB and TEXT values in the same database.
[0071]
[0077] The configuration database maintains application and schema version strings to verify that the application version of the control system matches the database version. At the start of the application, the version strings are checked and equality is compared. Version mismatches can lead to unpredictable behavior and software crashes due to components attempting to read data values of unrecognized types and formats.
[0072]
[0078] The configuration subsystem is functionally designed. Each system component, service, and subsystem knows its configuration. The configuration subsystem provides a set of simple methods with some overrides that accept a configuration parameter name and its value. Method overrides accept additional parameters that may include type information and other metadata parameters necessary to store the parameter appropriately.
[0073]
[0079] Configuration changes made in the system are written to the audit log using the reporting subsystem. The audit log must include the configuration settings, the operator who made the configuration change, and the date / time stamp when the configuration setting was changed.
[0074]
[0080] The control system has the ability to save configuration profiles. The configuration profile represents a group of configuration settings including the placement of the applicators, the volume of ionized hydrogen peroxide (iHP) to disperse, the number of applicators to activate, and the name of the location where the applicators are to be executed.
[0075]
[0081] The configuration profile is stored using the browser interface, can be saved and loaded on demand by the system operator. The configuration subsystem provides remote configuration and calibration access via browser access by exposing functions via the API gateway when the unit is connected to the Internet (6).
[0076] Device Driver Subsystem
[0082] The device subsystem manages a plurality of devices and sensors used by the control system. The device driver subsystem provides operation control and access to the set of sensors of the control system and the connected applicators.
[0077]
[0083] The application services and subsystems cannot directly access the hardware underlying the control system. The device driver subsystem is designed for single-threaded access and uses a functional command operation mode. The device driver subsystem abstracts the object representing the hardware device and the driver necessary to control the device.
[0078]
[0084] Similar to other subsystems, the driver interface exposes function calls to higher-level software components. These functions are named for the operations to be performed on the lower-level hardware. This abstraction is implemented using a low-level command set that sends serial commands to the control board hardware via the USB interface. The command set is the actual driver used to control the operation of the applicator, make measurements, monitor sensors, and call read values on the RFID reader.
[0079]
[0085] The command set provides pin / in-out operations that can read the voltage value on a specific PIN on the control board and return it to the higher-level call function. The control system is connected to multiple control boards that provide general-purpose VOs. The control board provides the ability to read input voltages from multiple pins. The device subsystem provides the ability to assign one or more I / O pins for specific transmission directions and application requirements. For example, PinO can be used for the control and measurement of a flow meter, where Pin16 is used to receive input signals from a SCADA device. The device subsystem exposes multiple functions that assign VO operations to specific pin numbers on the control board. This provides a high-level application abstraction with the ability to perform device-specific operations without the need to know how to communicate with the underlying hardware. The input read voltage is used to determine the volume of the flow meter. In one embodiment, the input voltage is read between 0 and 5 volts. The input read voltage is used to read events from proximity sensors. These values are determined when a proximity sensor is selected in a set of sensors.
[0080]
[0086] The device subsystem manages the communication between the control system software and its underlying hardware resources (applicator, driver, sensors, etc.). This constitutes a device data pipeline since the device subsystem processes the instruction sets of multiple discrete sensor devices.
[0081]
[0087] Figure 6 shows the event state change design of the device driver subsystem. The subsystem management component (device manager) provides means to add, enable, disable, and remove devices. A device may include any communicable hardware including an applicator. The device manager supports monitoring of multiple devices in the pipeline through exposed functions.
[0082]
[0088] The subsystem provides the ability for high-level components and services to be notified when a sensor or other hardware device (e.g., an applicator) encounters a state change, using the capabilities provided by the warning and event subsystem. The observer pattern implementation of the warning and event subsystem provides this notification ability.
[0083] Event Subsystem
[0089] The event subsystem supports the reception of software and hardware events from multiple sources.
[0084]
[0090] In certain embodiments, the event subsystem reuses the registration and issuance design of the warning subsystem and adapts the object model and execution components to the event subsystem. The internal components and external software interfaces reuse mechanisms similar to those designed by the warning subsystem. The event subsystem processes events that may arise from hardware and software and dispatches the events to interested subsystems and components to take countermeasures.
[0085]
[0091] Most hardware events are sourced from the control board hardware originating from the application code or from one or more sensors attached to the control board hardware. Additionally, Supervisory Control And Data Acquisition (SCADA) systems and other external devices may be connected to the control system using one of the available digital or analog pins available on the control board hardware. The system configuration provides the ability to identify which PIN the hardware device is connected to and the voltage requirements that need to be read from the PIN.
[0086]
[0092] Hardware event detection is performed using a configurable polling method that checks the values of multiple VO pins. When a state change occurs, the producer / consumer mechanism is used to notify any services or components registered for a particular hardware event change. External services and applications must register a RESTful webhook that the control system can call to receive hardware event notifications.
[0087]
[0093] The event subsystem also plays a role in responding to any shutdown events. Shutdown events can occur internally due to an irrecoverable anomaly or error, the operator initiating a shutdown via a browser or API, or a hardware event such as pressing an emergency button or relay cutoff. Like all other events, the event subsystem processes the shutdown event. After the event is processed, the event subsystem dispatches the event to the system controller, which is used to gracefully or forcefully terminate the control system.
[0088]
[0094] The event subsystem provides the ability to optionally send warnings for specific events. In some use cases, it may be necessary to send warnings when the application starts and ends. When an event is triggered via a browser-based configuration panel, the operator can configure the control system to send the warning to specific recipients via email.
[0089] Reporting subsystem
[0095] The reporting subsystem is the primary controller for serializing the data generated by the control system. Further, the reporting subsystem is used to generate multiple logs including system and audit logs.
[0090]
[0096] The reporting subsystem uses an embedded database to store analysis and execution data. The database used to store the analysis may be the same database used to store the configuration parameters. As a change to the system requirements, additional analysis items may be added. All analysis values are stored using appropriate key-value pairs and use object storage as needed. After the application execution is completed, the analysis data is not changed and is marked as read-only.
[0091]
[0097] The application execution analysis is available at any time and can be used to generate reports. The reporting subsystem provides the ability to export the application execution analysis in PDF. The PDF report is rendered to be tamper-resistant to meet pharmaceutical guidelines. The reporting subsystem exposes access to the analysis data via an API gateway. This provides the system with the ability to distribute analysis information via the cloud by retrieving data from a control system unit connected to the Internet.
[0092]
[0098] The reporting subsystem exposes functions for generating multiple logs via a logger. Standardized logging packages are used to generate logs throughout the system (such as log4j, Winstone, etc.). In certain embodiments, the control system writes three types of logs: a system log that tracks system events and notifications throughout the system, an audit log used to track user-driven events and configuration changes, and an execution log that tracks the execution and execution analysis of the applicator. The logs can be retrieved via a browser interface and downloaded as text files for later inspection.
[0093]
[0099] The logger must write the following items to the configured logs. · Date / time of the log message · Log text · Subsystem · Log level (debug, error, info, warning) Software Development Kit (SDK)
[0094]
[0100] The SDK (Software Development Kit) provides the ability for technically advanced users to build applications on the control system. The SDK is designed to build applications on publicly available services exposed by the control system. The user determines which services are publicly available and which other services are reserved. Reserved application services are important for the reliable operation of the control system and may cause unpredictable behavior if changed by the end user. Possible reserved services may be calibration functions for specific hardware. The user may decide that the end user should not have the ability to calibrate the hardware and that the function should be reserved for the user technician. Reusing the API gateway platform facilitates access to the SDK.
[0095] Security
[0101] Operator security is managed by access to the browser application with a username and password. The web application uses role-based access control (RBAC) to restrict access to protected configuration settings and control specific behaviors within the system. The roles and configuration settings and behaviors are determined by the user.
[0096]
[0102] Connection security is possible by using an SSL certificate that encrypts the communication between the web server and the browser. NGINX facilitates the installation of an SSL certificate that provides the ability to secure browser communication. The SSL certificate must be installed on the computer by SSH processing and securely copied to the certificate store of NGINX.
[0097]
[0103] API keys manage external access to the API gateway. An API key is a unique value generated for a software program to communicate with web resources. Secure access to the control system is implemented using an API key, and a new API key must be generated for each application that requires programmatic access to the control system.
[0098]
[0104] The control system web application utilizes the same API gateway interface for communication and control. Since the web application server is a special application with access permitted, local security is performed by API key and local IP address binding. The SSL certificate may also be used to secure the communication channel between the web browser and the external application. SSL security is implemented by using the native capabilities provided by the web server installed on the control system.

[0159] Example 2 Customized engineering system
[0191] Effective disinfection by activated hydroxyl ions used in this application depends on the surface area of the droplets applied to the surface, i.e., the smaller the droplets, the larger the surface area of the activated hydroxyl ions over the entire cloud of droplets, and thus the more effective the disinfection method. In fact, when the surface is immersed, the activated ions do not come into contact with bacteria for disinfection, so when the surface for disinfection is immersed, the effectiveness of the activated hydroxyl ions is impaired.
[0160]
[0192] Activation of the cleaning fluid to generate activated hydroxyl ions can occur through the passage of the fluid, for example, via an arc current, an electromagnetic field, or photonic energy. The fluid may be generated in a spray form, for example, via atomization, ultrasonic waves, pneumatic spraying, or mechanical pressure. However, since the blower generates a strong flow of large droplets that immerse the surface in the fluid, all of which weaken the effect of the activated hydroxyl ions, the blower is not used in the method of the present application for generating in a spray form.
[0161]
[0193] The method of the present application requires that a very fine mist (extremely small diameter aerosol particles described herein) that transports activated hydroxyl ions through the space to the surface be generated for pollution removal. The activated hydroxyl ions come into contact with pathogens before recombining to form harmless molecular oxygen and water (the advantage of the method herein is that no chemical residues remain on the disinfected surface). A preferred embodiment of the present application uses a cleaning fluid containing 0.3% to 9% hydrogen peroxide as a source of active species for pollution removal of articles or substantially enclosed spaces. The preferred aerosol droplets for transporting the activated hydroxyl ions have a diameter of 0.3 to 1.0 microns, and most preferably have an average diameter of 0.7 microns. Therefore, any automated system applying this method requires precise parameters for performance.
[0162]
[0194] Preferred methods and techniques for use in a contaminant removal process are described in U.S. Patent No. 10,391,188, which is incorporated herein by reference. A contaminant removal fluid mist is activated to produce an activated contaminant removal fluid mist. The activation produces activated species of the contaminant removal fluid material in the mist, such as in an ionized state, a plasma state, or a free radical state. At least some of the activatable species are activated, and optionally, if any, some of the promoting species are activated. To improve the efficiency of the contaminant removal process, a high yield of activated species is desired, but it is not necessary for all or most of the activatable species to achieve an activated state. Any operable activator may be used. The activator field or beam may be electrical or photonic. For example, it includes an alternating current electric field, an alternating current arc, a direct current electric field, a direct current arc, an electron beam, an ion beam, a microwave beam, a radio frequency beam, a high frequency beam, and an ultraviolet light beam generated by a laser or other source. By the activator, at least some of the activatable species of the contaminant removal fluid in the contaminant removal fluid mist are excited to an ion, plasma, or free radical state, thereby achieving "activation". These activated species enter into a redox reaction with the cell wall of the microorganism, thereby destroying the cells or at least preventing their growth and proliferation. In the case of preferred hydrogen peroxide, at least some of the H2O2 molecules dissociate to produce activated species of hydroxyl (OH-) and monoatomic oxygen (O-) ions. These activated species remain dissociated for a period of usually several seconds or more while attacking and destroying biological microorganisms. The activator is preferably adjustable with respect to the frequency, waveform, amplitude, or other characteristics of the activation field or beam, whereby the activator may be optimized to achieve a maximum recombination time for the action on biological microorganisms. In the case of hydrogen peroxide, the dissociated activated species recombine to form diatomic oxygen and water, becoming harmless molecules.
[0163]
[0195] An applicator having a cryogenic plasma arc that seeks pathogens, kills them, inactivates them, and divides a hydrogen peroxide-based solution into reactive oxygen species including hydroxyl radicals is included in an exemplary contamination removal device / system of the present disclosure. The activated particles generated by the applicator kill or inactivate a wide range of pathogens and are safe for sensitive equipment. Generally, the contamination removal device / system of the present disclosure enables effective treatment of an exemplary space of about 104 m2 in about 75 minutes, including application time, contact time, and exposure time. The contamination removal device / system of the present disclosure is scalable and configurable to be effective in spaces / rooms / chambers / containers of any size or volume. Scalability may be achieved by device size, manual control of the contamination removal fluid, or programming the air pressure of the device and the resulting fluid flow rate as a function of input space / room / chamber / container parameters.
[0164]
[0196] Conventional methods of contamination removal are not very effective for decontaminating enclosed spaces. This application discloses that decontamination using a Vaporized Hydrogen Peroxide Mist containing ionized hydrogen peroxide results in unexpectedly high levels of kill rates of pathogens (including bacteria, fungi, protozoa, or viruses), such as Candida auris, in small enclosures, semi-enclosed spaces, and closed areas (a small enclosure is an area of 12 inches × 12 inches × 12 inches or less, a semi-enclosed space is an area where a portion of the small enclosure is open to another area, and a closed area is an area where no portion of the small enclosure is open to another area).
[0165]
[0197] Berry dry mist is a mist of particles with a particle size in the range of about 0.1 to 0.2 microns, 0.1 to 0.3 microns, 0.1 to 0.4 microns, 0.1 to 0.5 microns, 0.1 to 0.6 microns, 0.1 to 0.7 microns, 0.1 to 0.8 microns, 0.1 to 0.9 microns, 0.1 to 1 micron, 1 to 1.1 microns, 1 to 1.2 microns, 1 to 1.3 microns, 1 to 1.4 microns, 1 to 1.5 microns, 1 to 1.6 microns, 1 to 1.7 microns, 1 to 1.8 microns, 1 to 1.9 microns, 1 to 2 microns, 0.5 to 0.6 microns, 0.5 to 0.7 microns, 0.5 to 0.8 microns, 0.5 to 0.9 microns, 0.5 to 1 micron, 0.5 to 1.1 microns, 0.5 to 1.2 microns, 0.5 to 1.3 microns, 0.5 to 1.4 microns, 0.5 to 1.6 microns, 0.5 to 1.7 microns, 0.5 to 1.8 microns, 0.5 to 1.9 microns, 0.5 to 2 microns, 0.5 to 2.1 microns, 0.5 to 2.2 microns, 0.5 to 2.3 microns, 0.5 to 2.4 microns, 0.5 to 2.5 microns, 0.5 to 2.6 microns, 0.5 to 2.7 microns, 0.5 to 2.8 microns, 0.5 to 2.9 microns, 0.5 to 3 microns, 0.5 to 3.1 microns, 0.5 to 3.2 microns, 0.5 to 3.3 microns, 0.5 to 3.4 microns, or 0.5 to 3.5 microns. In certain embodiments, the berry dry mist has particles with a particle size in the range of about 0.5 to 3 microns, preferably an average of 0.7 microns.
[0166]
[0198] In certain embodiments, the customized engineering system described herein monitors the size of the aerosol droplets produced, such that the aerosol droplets that transport activated hydroxyl ions form a bell-shaped distribution as described herein. In preferred embodiments, at least 80%, 90%, 95%, 100% of the collection of aerosol droplets are within a size range of 0.3 to 1.0 microns in diameter. In certain embodiments, the size of the aerosol droplets is monitored by use of a laser scan of the aerosol droplet size. Optical measurements may be performed using a sensor or particle detector placed in a detection zone after the activation point of the hydroxyl ions on the aerosol droplet, and the sensor may be an optical particle counter (OPC), a laser particle counter (LPC), or a condensation particle counter (CPC). The OPC or LPC can detect particle sizes greater than 0.1 micron. The customized engineering system comprises a computer processor as described herein that receives data regarding the size range of the aerosol droplets that transport activated hydroxyl ions. The customized engineering system is programmed to adjust control parameters that manage the size of the particles in the bell-shaped distribution to maintain the collection of aerosol droplet sizes within a desired range.
[0167]
[0199] The customized engineering system includes a programming clock and uses one or more potentiometers to provide pneumatic control and fluid flow control. The programming clock provides the ability to automate the cycle of contamination removal within a small enclosure. The cycle of contamination removal controlled by the programming clock includes, for example, a cycle of spraying the bell-shaped distribution for 30 seconds, a cycle of stopping the spraying for 10 seconds, and then a cycle of resuming the spraying for another 30 seconds, and such cycles may be repeated for a certain period. The programming clock can be set manually by the user or can be controlled remotely wirelessly by the user or a computer processor using a pre-programmed contamination removal cycle transmitted to the device for deployment.
[0168]
[0200] In certain embodiments, the time during spraying may be 10 to 1800 seconds, 10 to 1200 seconds, 10 to 900 seconds, 10 to 600 seconds, 10 to 300 seconds, 10 to 180 seconds, 10 to 150 seconds, 10 to 120 seconds, 10 to 90 seconds, 10 to 60 seconds, 10 to 45 seconds, 10 to 30 seconds, 30 to 1800 seconds, 30 to 1200 seconds, 30 to 900 seconds, 30 to 600 seconds, 30 to 300 seconds, 30 to 180 seconds, 30 to 150 seconds, 30 to 120 seconds, 30 to 90 seconds, 30 to 60 seconds, 30 to 45 seconds, 60 to 1800 seconds, 60 to 1200 seconds, 60 to 900 seconds, 60 to 600 seconds, 60 to 300 seconds, 60 to 180 seconds, 60 to 150 seconds, 60 to 120 seconds, 60 to 90 seconds, 90 to 1800 seconds, 90 to 1200 seconds, 90 to 900 seconds, 90 to 600 seconds, 90 to 300 seconds, 90 to 180 seconds, 90 to 150 seconds, 90 to 120 seconds, 120 to 1800 seconds, 120 to 1200 seconds, 120 to 900 seconds, 120 to 600 seconds, 120 to 300 seconds, 120 to 180 seconds, 120 to 150 seconds, 150 to 1800 seconds, 150 to 1200 seconds, 150 to 900 seconds, 150 to 600 seconds, 150 to 300 seconds, 150 to 180 seconds, 180 to 1800 seconds, 180 to 1200 seconds, 180 to 900 seconds, 180 to 600 seconds, 180 to 300 seconds, 300 to 1800 seconds, 300 to 1200 seconds, 300 to 900 seconds, 300 to 600 seconds, 600 to 1800 seconds, 600 to 1200 seconds, 600 to 900 seconds, 900 to 1800 seconds, 900 to 1200 seconds, or 1200 to 1800 seconds.
[0169]
[0201] In certain embodiments, the time between two resultant sprays may be 1 - 600 seconds, 1 - 300 seconds, 1 - 180 seconds, 1 - 150 seconds, 1 - 120 seconds, 1 - 90 seconds, 1 - 60 seconds, 1 - 45 seconds, 1 - 30 seconds, 1 - 15 seconds, 10 - 600 seconds, 10 - 300 seconds, 10 - 180 seconds, 10 - 150 seconds, 10 - 120 seconds, 10 - 90 seconds, 10 - 60 seconds, 10 - 45 seconds, 10 - 30 seconds, 30 - 600 seconds, 30 - 300 seconds, 30 - 180 seconds, 30 - 150 seconds, 30 - 120 seconds, 30 - 90 seconds, 30 - 60 seconds, 30 - 45 seconds, 60 - 600 seconds, 60 - 300 seconds, 60 - 180 seconds, 60 - 150, 60 - 120 seconds, 60 - 90 seconds, 90 - 600 seconds, 90 - 300 seconds, 90 - 180 seconds, 90 - 150 seconds, 90 - 120 seconds, 120 - 600 seconds, 120 - 300 seconds, 120 - 180 seconds, 120 - 150 seconds, 150 - 600 seconds, 150 - 300 seconds, 150 - 180 seconds, 180 - 600 seconds, 180 - 300 seconds, or 300 - 600 seconds. In one example, the time between two resultant sprays is 60 seconds.
[0170]
[0202] In some cases, the time during spraying is 90 seconds and the interval between sprays is 60 seconds. In some embodiments, the spray cycle includes a spraying time and a pause time, and the complete decontamination process includes 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 spray cycles (spray cycle = spray + interval - total number of cycles).
[0171]
[0203] In certain embodiments, a customized engineering system comprises a computer processor capable of calculating appropriate settings (e.g., flow rate, air pressure, number and length of decontamination cycles) to generate a Belide mist containing ionized hydrogen peroxide for effectively decontaminating an enclosed space. In such embodiments, the user may manually enter the parameters of the enclosure into the device or remotely via a wireless connection. The operation of the system can be fully automated, fully remotely controlled, or semi - automated (e.g., using decontamination cycles that are automatically performed according to manually entered parameters).
[0172]
[0204] Reducing excessive air pressure generates mist particles that are too large to achieve the desired mist / fog profile, which is a common problem in the prior art. At the same time, especially in enclosed spaces, significant air pressure reduction is often required. These opposing constraints of the pollution removal system are addressed by certain embodiments of the present disclosure. That is, by programming a processor to control a potentiometer based on the input parameters of a small housing, a user can adjust the fluid flow rate in synchronization with the air pressure. As a result, by reducing the fluid flow rate while simultaneously reducing the air pressure, the size of the mist / fog particles is maintained small while limiting the distance the spray can reach. In this way, the mist sprayed by the customized engineering system stays within the boundaries of the enclosed space without generating an overly wet and dense fog. Thus, the programmable balance between air pressure and fluid flow rate prevents saturation of the surface opposite the mist applicator, increased moisture accumulation due to condensation, false negative verification results, or increased aeration time of the housing.
[0173]
[0205] In some embodiments, the customized engineering system may include or be configured to access a database that lists the characteristics of the room in which the customized engineering system is deployed. Additionally, or alternatively, the customized engineering system may include a system for collecting and / or generating data regarding the characteristics of the room in which the customized engineering system is deployed. In such cases, any system known in the art for collecting, generating, and / or analyzing the characteristics of the room may be used depending on the data generated. Examples include spatial sensors, optical recognition systems, and / or dosimeters. The system may be operably coupled to a CPU in some embodiments. Alternatively, the CPU may be configured to access the room characteristic data from the database. In either case, the CPU may be configured to search for, access, and determine the operating parameters of an applicator for applying ionized hydrogen peroxide, such as the position of the applicator, based on the data regarding the characteristics of the room in which the customized engineering system is deployed. In some embodiments, the determined operating parameters may be relayed via a user interface such that a user of the customized engineering system can be notified to invoke the operating parameters of the customized engineering system. In other cases, the CPU may be configured to send commands to means within the customized engineering system for automatically invoking the operating parameters, such as automatically moving the direction of the spray of the applicator according to the determined operating parameters.
[0174]
[0206] In some embodiments, the system may be used to measure the dosage of ionized hydrogen peroxide received at an object or spot in a room where a customized engineering system is deployed. In particular, measuring the dosage of ionized hydrogen peroxide at an object or spot in a room can help determine the operating parameters of the applicator, such as optimizing the placement of the applicator. As described above, one of the main factors affecting the effectiveness of ionized hydrogen peroxide on an object is the distance to the object. Through the operation coupling of the system to the CPU, the CPU obtains measurement values from the system, determines the operating parameters of the applicator based on the measurement values such as the position of the applicator, relays the determined operating parameters to the user interface, and / or transmits commands to the means within the customized engineering system to automatically invoke the operating parameters of the applicator, such as the applicator, according to the determined operating parameters. Generally, any system known in the art for measuring spray dosage may be used in the system.
[0175]
[0207] The customized engineering system may include or be configured to access a database listing the characteristics of one or more rooms, and / or the device may further include a system for collecting and / or generating data regarding the characteristics of the room. Any system known in the art for generating, collecting, and / or analyzing the characteristics of a room may be used. Examples include dosimeters, space sensors, and / or optical recognition systems. In some cases, the device may further include a CPU for obtaining data, determining the position of the applicator based on the data, relaying the determined position to the user interface, and / or transmitting commands to the means within the customized engineering system to automatically move the applicator according to the determined position.
[0176]
[0208] In certain embodiments, the customized engineering system comprises laser diffraction technology for quantifying the particle size distribution within the spray. The applicator is externally mounted in the ambient air and the spray moves through an enclosed nozzle. The spray is formed by ultrasonic or similar means generated within a chamber in the customized engineering system and the spray flows out to the outside air through the applicator. On its way through the nozzle, the spray moves through a zone where the laser is projected and thus the laser beam diffracts after colliding with the particles. A collection of sensors on the opposite side of the laser source measures these diffraction patterns and interprets them using Mie theory (analytical solution of equations for the scattering of electromagnetic radiation by spherical particles) to quantify the particle size distribution of the ionized particles within the spray. Since the method herein depends on the application of bellidolymist, the customized engineering system can be programmed to adjust the air valve or other operating parameters to appropriately maintain the average diameter of the ionized particles determined by the laser diffraction technique low.
[0177]
[0209] In certain embodiments, when a customized engineering system is ready, the customized engineering system automatically launches and executes a mission, such as a cleaning mission. In certain embodiments, the customized engineering system includes a motion sensor capable of detecting the presence of humans in the area. The customized engineering system includes an alarm mechanism such as an audible warning and / or a flashing light when a human is detected in the operating area. The customized engineering system automatically moves away from the human, quiets itself, or turns off its power to quiet the customized engineering system when a human is present. Thus, the customized engineering system operates smartly by interrupting its mission so that humans are not affected by the spray. The contamination removal customized engineering system monitors the movement of humans in its operating area and, in embodiments, monitors the departure of humans from the area including a time delay before reactivation. When a human leaves the area, the customized engineering system autonomously returns to the location where it interrupted its mission and completes the coverage of the room. Thus, the customized engineering system completes its mission across the space while adapting to the presence of humans in the space.
[0178]
[0210] An embodiment of a customized engineering system is shown in FIG. 7. The user starts the start of the cycle - the system delays the start of the system (either manually or by a signal sent from the system) so that the HVAC is shut down. As can be seen in FIG. 7, the ionized hydrogen peroxide (iHP) spray cycle starts when the start button is pressed (this can be done through the network system described herein via the user interface). Following the pressing of the start button, the spray cycle delay start timer starts its countdown. This allows any individuals in the area to clear out before contamination removal begins. It also gives individuals time to leave before the door is locked so that the area for contamination removal is sealed. The system may trigger an alarm warning that emits a warning sound to warn individuals in the area targeted for contamination removal and / or an audible warning in a language, for example, including a countdown in the language, within the area for contamination removal. Notification devices such as lighting or a buzzer may be present on an applicator placed within the area for contamination removal, and these notification devices start flashing or buzzing to warn individuals in the area who should exit. An output signal is sent from the customized engineering system to the building HVAC system to warn the HVAC system that the spray is active, but the ionized hydrogen peroxide spray does not start at this point. Instead, the system waits for a signal from the HVAC system that the air flow has stopped in the target area for contamination removal. The delay start countdown does not end until the customized engineering system receives an input signal from the HVAC system that the air flow has been shut down. The output signal is also sent from the customized engineering system to the building door lock system, and the system waits for a door lock input signal to confirm that all doors are locked before ending the delay start countdown.
[0179]
[0211] The spray cycle starts when the system receives notice that all doors are sealed and the air flow is interrupted. The customized design system monitors the amount of solution required both in terms of the flow rate during injection and the total amount delivered. (If the system detects a loss of flow from any applicator, the system is abnormal - if two or more applicators are installed in the processing area, the system can be programmed to close the cycle or continue with the remaining applicators until the correct required amount of solution is delivered.)
[0180]
[0212] The spray cycle ends based on programmed parameters, after which the dwell cycle starts. The dwell starts after the injection cycle. (This pause period is time-adjustable and can be adjusted by the customer.) During the dwell cycle, the customized design system is in a standby state and the processing area remains under the control of the customized design system.
[0181]
[0213] When the dwell cycle ends, an output signal is sent from the customized engineering system to the HVAC system release. After dwell, aeration starts. The customized design system signals to turn on the HVAC / exhaust system (if equipped).
[0182]
[0214] After the HVAC system is released, the HVAC system turns on again, and an aeration cycle begins in which air flow / ventilation is restored. The aeration cycle proceeds to remove residues of ionized hydrogen peroxide decontamination (diatomic oxygen and water as described herein) from the room based on time, based on measurement of an air sample in parts per million (PPM), or both. When the aeration cycle is complete, an output signal is sent from the customized engineering system to the door lock system and released. The system can monitor the exhaust of the treatment area for residual concentration of the solution (all doors remain locked until a pre-set safety level is achieved), or the system can be set to release the doors at a pre-set time.
[0183]
[0215] The system may comprise a camera and the ability to view the area to be decontaminated through the camera, and the camera view may be evaluated by the user or by an algorithm designed to recognize movement of humans or animals within the area for decontamination if the algorithm recognizes movement such that the spray cycle is abnormal until the problem is solved.
[0184]
[0216] Air CDA is also monitored during the injection cycle for deficiencies at each applicator and at the inlet of the air supply source. Arcs are also monitored at each applicator. Air monitors are placed in appropriate locations to view PPM level monitoring. If each area to be decontaminated has a separate exhaust and can be operated individually, individual low-level monitors can be used for each treatment area. The monitor monitors peak PPM at the start of the aeration cycle to provide a data set point (providing a range from the maximum PPM level to the minimum PPM level).
[0185]
[0217] When the cycle is completed, the system can send information to the user server for distribution if the user deems it necessary. When there is an abnormality in the cycle, the system can send information to the user server for distribution if the user determines it is necessary.
[0186]
[0218] In certain embodiments, the customized engineering system is used to cover a sealed room in medical, industrial, commercial, and facility environments with a mist. The amount used to achieve the minimum atomization concentration of ionized hydrogen peroxide is 0.5 ml per cubic foot of enclosure (room) volume. The software calculates the dosage based on the input volume and measures that the correct dosage is dispensed via the applicator. The application time required to achieve the required concentration varies depending on the size of the room and the number of applicators. Once the minimum mist concentration is achieved, a dwell time of at least 15 minutes must be maintained before starting the aeration of the room. In certain embodiments, the system starts from these pre-set parameters (dosage rate / contact time). In certain embodiments where the system can evaluate a changing environment (e.g., the presence of large-scale equipment), the system may have the ability to adjust. The room is aerated until a standard air monitor indicates that the hydrogen peroxide is less than 1 part per million (PPM). Once the room is properly aerated, one can enter the room without personal protective equipment and return to service. Aeration occurs naturally without mechanical assistance if time is not a factor. Venting to the outside of the building, all air scrubbers and fans can be used after contact to speed up the aeration process. A HEPA filter with a dehumidifier, fan, or carbon filter is also effective in removing suspended hydrogen peroxide. Since ionized hydrogen peroxide decomposes into humidity and oxygen, there is no need to wipe it off and no residue remains after treatment.
[0187] Example 3 Immune Building
[0219] The customized engineering system is fully automated. This system is integrated with the facility's HVAC system. Once installed, the system can depend on either preset parameters or specifications determined by the system user or a technical consultant. In certain embodiments, the system includes a programmable logic control housed in a central location. In certain embodiments, the system is controlled by an algorithm that uses machine learning and preset parameters to determine the control and performance of the decontamination system. The machine learning neural network is trained to identify differences between spray cycles, aeration cycles, and environmental responses and input parameter steps described herein. The neural network then acts as artificial intelligence to control the decontamination system described herein based on environmental inputs resulting from different sensor signals regarding the presence of pathogens within the building. The user may assume control of the customized engineering system from the artificial intelligence, operate via manual commands delivered through the user interface, or reprogram the preferred preset parameters. The use of artificial intelligence to control the installed and fully automated customized engineering system to perform the decontamination cycles described herein creates an immune building. The customized engineering system functions as an immune system that automatically responds to detected threats by initiating decontamination in specific contaminated areas of the building as described herein. Based on the identification of specific biological hazards, different spray cycles and dwell cycles can be appropriately initiated to eliminate the identified biological hazards. The program allows for multiple cycles to be held by the system and accessed for deployment. The programming also allows for cycle continuation when multiple pods fail or malfunction, redirecting remaining doses to remaining applicators rather than stopping them. The system can be used for various specifications in multiple rooms and is remotely controlled via the user interface described herein.
[0188]
[0220] In certain embodiments, the immune building system is used for decontamination and sterilization of a designated area. The immune building must be able to sterilize up to the total volume of the designated area. The immune building system comprises at least one decontamination agent container, a decontamination agent distribution pipe, a decontamination agent pump, a decontamination head (applicator), and a central control system. The number and position of the decontamination heads vary according to the location requirements. The immune building system starts when an operator (which may be artificial intelligence or, optionally, a manual user performing the control) initiates the decontamination process. The system checks the system state including, but not limited to, the available amount (optionally) of hydrogen peroxide, the expiration date of hydrogen peroxide, and the readiness of the system for operation. The system receives signal exchange with a network-connected HVAC system, and the HVAC system is instructed to stop and the immune building system receives confirmation that the stop has occurred. The injection of the decontamination solution as a spray mist described herein is started, and the ionization hydrogen peroxide injection is carried out up to a specified amount based on the volume. The spraying is concentrated on the worst-case locations for decontamination, and the consumption of the decontamination solution (per head) is monitored and evaluated by the system. The system gives time for contact to occur between the biological hazard and the sprayed ionization hydrogen peroxide mist. Thereafter, signal exchange is carried out to restart the system that was stopped to carry out the decontamination cycle. The system gives time for fresh air to flow until the ionization hydrogen peroxide concentration reaches less than 1 PPM. In particular, the confirmation of the safe concentration is monitored at the worst-case location for biological hazards.
[0189]
[0221] The immune building system is integrated with the HVAC system so as to be able to exchange signals with the HVAC control system. The system can transmit a stop HVAC signal and a restart HVAC signal. The system can receive confirmation of HVAC system stop or HVAC system restart from the HVAC control system in response to a given signal from the immune building system. The control system enables integration with optional equipment, and the system can transmit start, monitoring, and restart signals. The system can receive confirmation of system stop or system restart from an optional equipment filling line control system in response to stop and restart signals. The immune building system is ready to be fully automatically executed from the moment the process starts until the moment the process ends, including the generation of process reports. The immune building system is designed to ensure that sterilized rooms and substances are measured at the end of the cycle and that the residue of ionized hydrogen peroxide is less than 1 ppm.
[0190]
[0222] The immune building system enables adjustment of parameters such as at least the ionized hydrogen peroxide injection rate (per head), ionized hydrogen peroxide injection time, ionized hydrogen peroxide set point volume (concentration), ionized hydrogen peroxide contact time, aeration time, and aeration set point value (concentration) (optional). If the supply of ionized hydrogen peroxide during the sterilization cycle is temporarily interrupted, the cycle is interrupted and a warning is triggered. The sterilization cycle can be stopped at any time by manual override if necessary. A lockable emergency stop button is provided for manual override to stop ongoing decontamination. Visual displays such as an operating system (yellow), a warning system (red), and a system ready (green) may be installed or adjusted according to the user's needs. All ionized hydrogen peroxide equipment has one working time counter and one cycle counter each. The system can control the correct flow of individual heads. The system may purge all lines before the start of a new cycle towards the waste container.
[0191]
[0223] Changes to the set parameters can be made from the central operator interface. These changes may be made by an authorized access profile. The recipe configuration shall be possible by an authorized access profile. The operator can be aware of, check, and confirm the relevant warnings on the operation panel. In case of malfunction between the programming logic control and the controller, a machine error message is released. The system has an interface to an on-site IT network using an Ethernet connection. The system comprises an industrial PC that enables an operator interface, data input, data storage, and connection between the programming logic control and the controller. The recorder may record, store, archive, and retrieve important data of the process cycle. The system registers, generates, and issues data including different states of the process and equipment, measured values, warnings, and any other relevant information.
