The "Sentinel PureDrive" is an intelligent, adaptive in-car atmospheric defense system. Its primary goal is to establish and maintain a healthy and clean air environment within a vehicle cabin by actively monitoring, analyzing, and neutralizing airborne contaminants in real-time.
The invention addresses the limitations of standard passive cabin air filters in vehicles, which are often ineffective against ultrafine particles, viruses, and do not adapt to changing environmental conditions or occupant needs. The need for a more advanced, active, and adaptive solution for in-car air quality is highlighted.
The objective of this report is to analyze the provided unstructured text documents to identify existing technologies and concepts that constitute prior art relevant to the Sentinel PureDrive invention and to determine the extent to which this prior art supports or refutes the novelty of the invention as defined in the task.
This section analyzes the provided documents, breaking down the relevant prior art based on the key features and functionality of the Sentinel PureDrive invention.
Several documents describe systems utilizing multi-sensor arrays for monitoring environmental conditions. For instance, a patent on air quality monitoring systems [1, 5, 10] details an air monitoring unit with sensors to measure air quality data. These systems can be portable or installed and can include distributed sensor units. The sensors mentioned include those for carbon dioxide, particles, humidity, and TVOCs [1, 5, 10]. Another document related to controlling environmental conditions in enclosed spaces, including vehicle cabins, also describes a multi-sensor array with vision, acoustic, thermal, weight, pressure, capacitive, radio frequency, laser, humidity, and gas sensors to detect occupancy and internal/external conditions [6, 10].
The concept of monitoring both internal and external environmental conditions is present in the prior art. The air quality monitoring systems described in multiple documents explicitly mention a "source of environmental data from outside the building" [1, 5, 10] in addition to internal sensors. The system for controlling environmental conditions in enclosed spaces also notes the use of sensors to detect "external conditions (weather, sunlight intensity)" [6, 10] alongside internal conditions. A vehicle PM2.5 particle detection and purification device assembly includes both an air intake terminal inside the vehicle and an air intake terminal outside the vehicle, connected to a detector to detect air inside and outside [9].
While not directly related to air quality monitoring, the concept of using biometric data for system adaptation is present in the provided text. A biometric, personal authentication system uses unique biometric parameters (like fingerprints) and non-specific physiological characteristics (like pulse, EKG, blood oxygenation, or skin temperature) to verify if an individual is alive and in a suitable physical condition [13]. This system can optionally include measuring blood alcohol or controlled chemical substance levels to determine if a user is in a suitable physical condition to operate a motor vehicle [13]. This demonstrates the prior art's consideration of integrating physiological data for system control in a vehicle context, albeit for authentication rather than direct air quality adaptation based on health indicators like sneezing or coughing.
Multi-stage filtration is a well-established concept in air purification, as evidenced by several documents. An air purifier described in multiple sources [2, 5, 10] utilizes a series of different filters within a casing, including a prefilter for coarse dust, an electrostatic dust collector for fine dust, bacteria, and viruses, a chemical substance-capturing filter, and an activated carbon filter. This system aims to remove a wide range of pollutants through this combination. Another document describing a ventilation system for a combat vehicle crew cabin mentions an air suction and cleaning apparatus that includes a filter, potentially a chemical filter [11, 10]. A filter element document describes a multi-layered structure of non-woven filter media designed for removing both solid and liquid particles from a fluid stream, with layers arranged to create a pore size gradient [16].
While the term "Hyper-HEPA" is specific to the invention, the concept of high-efficiency particulate filtration is present. The air purifier with an electrostatic dust collector is claimed to remove fine particles "over 0.01 micron," bacteria, viruses, and tobacco smoke [2, 5, 10]. Standard HEPA filters are known to capture a high percentage of particles of a certain size. The invention's claim of capturing "up to 99.95% of particles down to 0.003 microns" with Hyper-HEPA filtration represents an advancement in the efficiency of particulate removal compared to standard HEPA or the electrostatic collector mentioned in the prior art.
Activated carbon filtration for adsorbing VOCs, odors, and harmful gases is a common technology described in the provided text. The multi-stage air purifier includes an activated carbon filter as the final stage [2, 5, 10]. A composite coconut shell activated carbon device for indoor air purification also utilizes activated carbon for adsorption [18]. Another document details activated carbon specifically for fuel purification, highlighting its capacity for adsorption [12, 10]. A patent on activated carbon filter paper and its preparation method describes its use in filtering applications, including for chlorine and organic impurities from water [17].
Photocatalytic Oxidation (PCO) is described as an active oxidation and purifying system. One patent details a system that enhances PCO by directing UV light onto active cell panels coated with a photocatalytic material (e.g., Titanium Dioxide) to break down toxic compounds into benign constituents [3, 5, 10]. This process can produce oxidizers like Hydroxyl Radicals, Vaporized Hydrogen Peroxide, Super Oxides, or Low Level Ozone [3, 5, 10]. Another document describes an advanced oxidation process using photohydroionization (PHI), which utilizes UV light and a hydrated catalytic surface (including titanium dioxide, silver, copper, rhodium, and a hydrating agent) to create advanced oxidation products that destroy microbes, odors, and chemicals [15]. A composite coconut shell activated carbon device also includes a photocatalytic oxidant layer on the outside of the carbon bag to enhance the elimination of bacteria, viruses, and organic gases [18].
Air ionization for removing airborne particles is also present in the prior art. An air purifier and ionizer combines mechanical filtration, electrostatic precipitation, and negative ion generation [4, 5, 10]. This device produces negative ions which interact with positively charged particles, causing them to agglomerate and be attracted to surfaces [4, 5, 10]. Another patent specifically describes an air ionizer apparatus and method for generating and controlling positive and negative air ions to neutralize electrostatic charges and remove particles [14].
The use of UV light for sterilization is mentioned in several contexts. The multi-stage air purifier can optionally include a germicidal lamp to irradiate the dust collection board of the electrostatic collector with ultraviolet rays to destroy microbes [2, 5, 10]. A UV-C LED air sterilization apparatus for vehicles is described, which can be retrofitted into existing ventilation systems to sterilize air using UV-C light [8]. This system uses UV-C LEDs at a frequency and intensity sufficient to kill germs and bacteria [8]. The PCO systems also utilize UV light, which can have germicidal properties [3, 5, 10, 15].
The concept of using expert systems or AI for analyzing environmental data and controlling systems is present. Air quality monitoring systems describe a computer with an expert system controlling the unit based on acquired data and providing analysis [1, 5, 10]. This expert system can use rule-based, case-based, or pattern recognition methods, including fuzzy logic and neural networks, and can learn from feedback [1, 5, 10]. The system for controlling environmental conditions in enclosed spaces also mentions an AI-Powered Adaptive Control Unit (processor) that analyzes sensor data and generates a routine to adjust the environment [6, 10].
Real-time analysis and response based on acquired data is a feature of the prior art. The air quality monitoring systems can adapt their operation in real-time based on acquired data [1, 5, 10]. The expert system can operate proactively to monitor for problems or reactively to diagnose issues [1, 5, 10]. The system for controlling environmental conditions in enclosed spaces also notes that the system can adapt in real-time [6, 10].
Predictive capabilities based on data analysis are discussed in the context of vehicle systems, although not specifically for air quality. Analysis of vehicle data can be used to predict potential component failures or diagnostic trouble codes using predictive models generated by machine learning [19]. Autonomous vehicle navigation systems use navigation processors to determine optimal routes by solving constrained minimization problems, considering external data and predicting vehicle behavior [7, 10, 20]. While these examples demonstrate predictive capabilities in vehicles, they do not specifically describe predictive air management based on navigation and external environmental data feeds for proactive cabin conditioning.
The concept of personalized settings or customization based on user input is present in the prior art, though not explicitly as "personalized profiles" for air quality sensitivity. Air quality monitoring systems can be customized based on building, occupant, and environmental information, driven by an expert system, and user input via a website can provide information for creating a customized monitoring program [1, 5, 10]. The system for controlling environmental conditions in enclosed spaces allows for different levels of sanitized conditions to be defined and potentially requested by users [6, 10].
While not explicitly detailed as a key feature in the provided prior art, the concept of monitoring system components is present in related fields. Analysis of vehicle data can be used to predict potential component failures [19]. This suggests that monitoring the health or performance of components like filters could be a logical extension within a comprehensive system.
Ventilation and filtration systems for vehicle cabins are described. A ventilation system for a combat vehicle crew cabin includes an air suction and cleaning apparatus with a filter [11, 10]. A vehicle PM2.5 particle detection and purification device assembly includes a purifier for purifying air inside and inhaled from outside the vehicle [9].
Specific air purification and sterilization technologies are applied to vehicle environments in the prior art. The UV-C LED air sterilization apparatus is specifically designed for vehicles and can be retrofitted into existing ventilation systems [8]. The document on active photocatalytic oxidation is cited by subsequent patents related to air purification devices, including those for vehicle ventilation systems [3, 5, 10]. The document on controlling environmental conditions in enclosed spaces explicitly discusses sanitizing enclosed spaces, such as vehicle cabins, using sensors and adjusting environmental conditions like light, heat, or humidity [6, 10].
Adaptive control systems are present in vehicles, particularly in the context of autonomous driving and HVAC control. Autonomous vehicle navigation systems adapt to real-time sensor data and external information to adjust routes and maneuvers [7, 10, 20]. HVAC control systems for buildings can adapt in real-time based on acquired data and energy characteristics [21, 10]. While these demonstrate adaptive control in vehicles and for environmental systems, the specific application of AI-powered adaptive control for real-time air quality analysis, predictive management based on navigation, and personalization within a vehicle cabin's atmospheric defense system is not fully disclosed.
The concept of a user interface for displaying information and receiving input is present in various systems. Air quality monitoring systems can have a local display, possibly a touchscreen, to provide real-time information and allow user input [1, 5, 10]. A website can host remote servers and allow users to access their data and reports via a web browser [1, 5, 10]. The system for controlling environmental conditions in enclosed spaces can be integrated with a user interface to collect input and provide information [6, 10]. While these examples demonstrate user interfaces and data access, the specific combination of a real-time in-car display for air quality, mobile app integration for remote control and scheduling, and voice control for an atmospheric defense system is not explicitly detailed in the provided prior art.
The provided prior art demonstrates that many individual components and concepts of the Sentinel PureDrive invention exist. Multi-sensor air quality monitoring, multi-stage filtration (including activated carbon and electrostatic precipitation), PCO, ionization, UV sterilization, expert systems/AI for environmental control, real-time adaptation, and in-car environmental systems are all described in various documents.
However, the novelty of Sentinel PureDrive appears to lie in the specific combination and integration of these elements within a dedicated, adaptive in-car atmospheric defense system, particularly with the inclusion of certain advanced features.
Specifically:
Based on the analysis of the provided unstructured text, the following elements of the Sentinel PureDrive invention appear to contribute to its novelty:
While elements of each of these concepts exist in isolation or in different applications within the prior art, their specific combination and application within a dedicated, adaptive in-car atmospheric defense system as described in the Sentinel PureDrive invention appear to present novel aspects.
The prior art documents reveal existing technologies related to air quality monitoring, various filtration and sterilization methods, adaptive control systems, and in-car environmental management. Concepts such as multi-sensor arrays, internal and external monitoring, multi-stage filtration, activated carbon, PCO, ionization, UV sterilization, expert systems/AI for environmental control, real-time adaptation, and user interfaces are all present in the provided text.
However, the Sentinel PureDrive invention distinguishes itself through the specific and integrated combination of these elements, particularly in the context of an adaptive in-car atmospheric defense system. The integration of external air quality data and navigation for predictive air management, the potential use of biometric feedback for personalized adaptation, and the specific combination of Hyper-HEPA filtration with Photocatalytic Oxidation (UV-C and catalyst) and Ionization in a single system appear to be novel aspects not fully disclosed in the provided prior art.
Therefore, while the invention builds upon existing technologies, the unique combination of features, particularly the predictive and personalized adaptive control based on a comprehensive sensor array (including external and optional biometric data) and the specific advanced multi-stage filtration and neutralization technologies, suggests that the Sentinel PureDrive invention possesses elements of novelty based on the provided unstructured text. Further prior art searches beyond the scope of the provided documents would be necessary for a definitive determination of patentability.
